Description

Temperature monitoring method for underground cable, temperature measuring host and medium

Technical Field

The application relates to the field of temperature monitoring, in particular to a temperature monitoring method, a temperature measuring host and a medium for an underground cable.

Background

Underground cables are cables that are often buried under the ground as compared to ordinary overhead lines, and are also called underground cables. The cable is made of one or more mutually insulated conductors encased in an insulating layer and a protective layer for the transfer of electricity or information from one place to another. After entering a modern society, due to reasons of shortage of urban land, high traffic pressure, urban construction and the like, underground cable transmission modes are generally adopted in large cities, and compared with overhead lines, the underground cable has the advantages of small occupied area, reliable transmission, high anti-interference capability and the like. When the underground power cable is carried for a long time, a heating phenomenon can be generated, if the cable is overheated, the current-carrying capacity and the service life of the cable can be reduced, and safety accidents such as fire of the cable can be caused when the cable is serious, so that a method for monitoring the temperature of the cable is needed to ensure the safe operation of the cable.

In the related art, the temperature of the underground cable is generally monitored by a wired or wireless temperature sensor. The wired mode is to connect the temperature sensor with the server control end through an electric connection mode, but the mode is not suitable for remote temperature data transmission, the wired temperature sensor is complex in wiring and unfavorable for quick deployment, and if one temperature sensor needs to be added or replaced, corresponding wired connection equipment is newly added, so that the wired temperature sensor is inconvenient and is troublesome in underground construction deployment. The wireless mode is that corresponding wireless communication equipment is arranged on the temperature sensor, so that the data of the temperature sensor can be directly transmitted to the server control end.

However, if the underground cable is covered with soil, cement, rock, etc., the signal transmission using the wireless temperature sensor is attenuated, the data reception is delayed, and the long-distance transmission further causes poor signal reception, so that in the case that the underground cable is covered with soil, etc., the related personnel cannot monitor the temperature change of the underground cable in real time.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

For ease of understanding, one related application of embodiments of the present application is described below.

In the related art, the temperature of the underground cable is generally monitored by a wired or wireless temperature sensor. The wired mode is to connect the temperature sensor with the server control end through an electric connection mode, but the mode is not suitable for remote temperature data transmission, the wired temperature sensor is complex in wiring and unfavorable for quick deployment, and if one temperature sensor needs to be added or replaced, corresponding wired connection equipment is newly added, so that the wired temperature sensor is inconvenient and is troublesome in underground construction deployment. The wireless mode is that corresponding wireless communication equipment is arranged on the temperature sensor, so that data of the temperature sensor can be directly transmitted to a server control end, but underground cables are covered by soil, cement land, rock and the like, signal transmission is attenuated, data reception is delayed, and signal reception is poor due to long-distance transmission, so that temperature change is difficult to monitor in real time.

By adopting the technical scheme of the embodiment of the application that the underground radio wave receiver of the temperature measuring host scans and identifies and processes the radio wave signals of the underground area, the technical scheme utilizes the penetrability of radio waves, scans the underground area through the underground radio wave receiver, acquires the data signals of the temperature sensor, identifies and processes the signals and filters out the temperature information, thereby realizing wireless remote monitoring of the temperature of the underground area, solving the problem of complex wiring of the wired sensor, overcoming the difficulty of easy attenuation of the radio signals and enabling the temperature monitoring of the underground cable to be more convenient and efficient.

The following describes a specific application scenario of the embodiment of the present application: the method comprises the steps of arranging a plurality of temperature monitoring sensors with wireless communication functions in an urban underground pipe network area, arranging a plurality of temperature measuring hosts at key ground positions, scanning the underground area and carrying out radio wave signal characteristic identification on the underground area to obtain radio wave signals of the temperature sensors, filtering, decoding, denoising and the like, extracting temperature data of the temperature sensors, and sending the temperature data to a server through a ground wireless network to realize real-time monitoring of temperature change of any underground cable.

According to the scheme for recognizing the underground temperature data through radio wave scanning, the remote wireless monitoring of the underground cable temperature information is realized, and the monitoring range and efficiency are greatly improved.

For ease of understanding, the method provided in this embodiment is described in the following in conjunction with the above scenario. Referring to fig. 1, fig. 1 is a schematic flow chart of a temperature monitoring method for an underground cable according to an embodiment of the application.

S101, scanning radio wave signals in an underground set range through an underground radio wave receiver;

a thermometry host may be provided with a plurality of subsurface radio wave receivers disposed in an area such as a subsurface pipe for scanning radio wave signals within the subsurface area.

The underground cable and the temperature sensor on the cable are blocked by soil, rock and the like, so that common wireless signals are difficult to spread, but the wireless electric wave signals have the characteristic of strong penetrating power. The present application takes advantage of this feature by scanning the subsurface range set by means of the subsurface radio wave receiver on the thermometric host. The continuous radio wave scans signals, which can penetrate soil, pipe structures, rock structures, etc., covering the subsurface region. Temperature sensors within the subsurface region will emit corresponding radio wave signals. For example, a plurality of temperature monitoring sensors are arranged in an urban underground pipe network, and the temperature sensors are integrated with a radio transmitting device. The temperature measuring host computer is provided with a plurality of radio wave receivers at key nodes such as pipe network inlets and the like, and has the capability of scanning underground areas. The radio wave receiver emits a scanning signal at a time interval, for example, once every 10 minutes, covering the entire set area. When the scanning signal activates a temperature sensor within the set area, the temperature sensor responds by transmitting a radio wave signal containing temperature data.

It should be noted that the radio wave signals in this step may also include other types of radio wave signals near the set area, such as radio frequency signals from other electronic devices, and the like.

S102, intensity screening is carried out on the radio wave signals to obtain radio wave signals to be identified;

Through the scanning of the previous step, the radio wave receiver acquires various radio wave signals of the underground area. These signals include both the effective data signal from the temperature sensor and possibly various noise interference signals. The received signal needs to be screened in order to filter out the valid signal for subsequent processing.

The step performs radio wave signal intensity screening, retains radio wave signals with intensities exceeding a set threshold as radio wave signals to be identified, and filters out signals with too weak intensities. Signal propagation is affected by distance attenuation and interference signals from too far from the receiver are very weak and can be excluded. And the effective data signal sent by the temperature sensor and close to the receiver has larger intensity and can be reserved.

For example, a radio wave signal strength threshold value of-80 dBm is set, and when the signal strength received by the receiver is higher than the value, the signal strength is closer to the distance and better in quality, and the signal strength is recorded as a radio wave signal to be identified; conversely, if the signal strength is below-80 dBm, the signals are considered to be too weak, possibly ambient noise, and the signals are filtered directly. Thus, effective data signals with enough intensity can be successfully obtained, and data support is provided for subsequent identification processing.

S103, carrying out electric wave characteristic recognition on the radio wave signal to be recognized to obtain a temperature characteristic electric wave signal, wherein the temperature characteristic electric wave signal is an electric wave signal sent by a temperature sensor;

And obtaining a batch of radio wave signals to be identified through signal intensity screening. These signals may be widely available and require further feature recognition to determine which signals are from the temperature sensor.

The electric wave signal emitted by the temperature sensor has the characteristics of specific frequency, coding, format and the like. The temperature measuring host machine extracts and matches the characteristics of the filtered radio wave signals to be identified one by one, such as frequency analysis, demodulation, format discrimination and the like, compares the characteristics of the radio wave signals to be identified with the electric wave signal template of the temperature sensor, and judges whether the signals come from the target sensor. The radio wave signal conforming to the characteristics of the temperature sensor is recorded as an effective temperature characteristic radio wave signal.

For example, an identification model of the temperature sensor electrical wave signal may be established for the characteristics of the frequency composition, modulation mode, packet format, etc. of the signal. After receiving the radio wave signal to be identified, inputting the characteristic parameters into a model, and judging whether the signal is matched with the temperature sensor. And if the model outputs a signal to be identified with the matching degree of more than 85%, judging that the signal is a temperature characteristic electric wave signal from the temperature sensor, wherein the temperature characteristic electric wave signal is an electric wave signal sent by the temperature sensor, and carrying out subsequent analysis processing.

Therefore, a large number of effective temperature characteristic electric wave signals can be effectively isolated through electric wave characteristic identification, and guarantee is provided for obtaining accurate underground region temperature data. The whole processing flow is automatically completed without manual participation, so that the rapid and intelligent identification of mass signals is realized.

S104, processing the temperature characteristic electric wave signals to obtain temperature data;

By the foregoing electric wave feature recognition, a large number of temperature feature electric wave signals from the temperature sensor are obtained. These radio wave signals contain encoded temperature data information, and analysis processing is required to obtain temperature data.

The temperature measurement host decodes the temperature characteristic electric wave signals and extracts temperature information in the temperature characteristic electric wave signals. The decoding mode needs to correspond to the encoding mode of the temperature sensor end, if the amplitude-shift modulated temperature signal is used, data can be obtained through amplitude demodulation, the obtained possible analog temperature is obtained, analog-to-digital conversion is needed, digital temperature reading is output, and the temperature reading data can be sent to the user end later.

The temperature measuring host machine obtains the processed accurate temperature data through decoding and processing the received temperature characteristic electric wave signals, and provides a data basis for subsequent analysis decisions.

S105, the temperature data is sent to the user side through an overground wireless communication transmitter.

After the processed temperature data are obtained, the processed temperature data are assembled into a data packet, and the data packet is sent to a monitoring center or other user terminals through an overground wireless communication transmitter of a temperature measuring host, so that real-time temperature monitoring of an underground cable is realized.

This requires the selection of an appropriate wireless or wired means to ensure that surface and subsurface temperature data can be communicated. When a wireless or wired communication scheme is selected, factors such as cost, communication distance, network rate, power consumption and the like need to be considered. In practical application, a proper wireless communication solution can be selected according to a monitoring scene, so that the temperature data can be reliably sent to the user terminal.

In the above embodiment, the acquisition of the temperature information of the underground area is realized through the scanning, the identification and the filtration of the radio wave signals, the scanning penetration of the radio wave signals is realized, the signal attenuation problem is solved through the identification and the filtration, namely, the double problems that the application range of the wired sensor is poor and the wireless signal is easy to attenuate and interfere are overcome, the acquisition of the temperature information of the underground area is realized, the remote wireless monitoring which cannot be realized by the wired sensor is realized, and the monitoring range and the monitoring efficiency are greatly improved.

In some embodiments, after the step of obtaining the temperature data after processing the temperature characteristic electric wave signal, the cable switch corresponding to the set range may be controlled to be turned off after detecting that the temperature data is greater than the maximum temperature value. Specifically, after the temperature measuring host processes the temperature characteristic electric wave signal to obtain temperature data, a maximum value of the temperature, for example, 80 degrees celsius, may be set, and the maximum value may also be set in advance by the temperature measuring host. The thermometric host then detects whether the temperature data collected by each temperature sensor is greater than the 80 degrees celsius maximum temperature value.

If data from either sensor is found to exceed the maximum temperature, this indicates that the cable temperature near that location is too high, with a potential risk of overheating. At this time, the temperature measuring host sends a control signal to a cable switch disconnection control unit.

After receiving the signal, the cable switch disconnection control unit judges a cable corresponding to the power supply of the underground area according to the position of the temperature sensor, sends a disconnection instruction, cuts off the power supply of the cable and prevents the cable from continuing to overheat.

Meanwhile, the temperature measuring host machine can prompt relevant maintenance personnel to go to the cable for checking and processing, and find out reasons of overheating of the cable, such as hot spots caused by poor contact, so as to avoid repeated occurrence of problems.

Therefore, when the temperature measuring host monitors that the temperature of the cable is too high, the power supply is cut off in time, so that accidents caused by further overheating of the cable can be effectively avoided, and the safe operation of the underground cable is ensured. This maximum temperature limiting mechanism can be an important means of cable overheat prevention and control in the power sector.

The following supplements the scenario of the present embodiment. Referring to fig. 2, fig. 2 is a schematic diagram of a scenario of a temperature monitoring method for an underground cable according to an embodiment of the application.

In fig. 2, a plurality of temperature sensors are installed in an underground area within a set range centering on a temperature measuring host, each temperature sensor is provided with a radio wave device, data of the temperature sensor can be emitted outwards in the form of radio wave signals, and other radio wave signal sources are arranged near the set range, such as a market provided with a device capable of emitting strong radio wave signals. In fig. 2, a solid line circle indicates a set range, a broken line circle indicates a propagation identification of an analog radio wave signal, and the temperature measuring host computer receives the radio wave signal of the set range including a temperature sensor and a radio wave signal transmitted from a mall through the underground radio wave receiver.

The temperature measuring host firstly carries out intensity screening on various radio wave signals, and filters out noise signals with weak intensity to obtain effective signals to be identified with sufficient intensity. Signal interference from remote markets may be filtered out, but some radio wave signals of too strong a radio wave strength may not be excluded. And then the temperature measuring host performs electric wave feature recognition on the filtered signal to be recognized, for example, a recognition model is built aiming at the features of the frequency, the modulation mode and the like of the signal, the signal is matched with a feature template of the temperature sensor, and the temperature feature signal is recognized. This may further remove interference from the market signal. After the temperature characteristic signal is obtained, the temperature measuring host decodes the temperature characteristic signal and the like to obtain temperature data. And finally, transmitting the temperature data of the underground area to a server or a monitoring center through an above-ground wireless communication transmitter.

Therefore, partial noise is filtered through signal intensity screening, and then the temperature signal is further isolated through electric wave characteristic identification. The method can filter the interference of other strong signals, identify weak signals, ensure that the collected signals are all effective temperature data, cannot be influenced by other radio wave signal sources such as a market and the like, and realize accurate monitoring of underground temperature. This can be stably and reliably operated even in a complex signal environment. Through the layer-by-layer identification and filtration, the problem of interference of other radio wave signals on underground temperature monitoring is solved, the range is wide, the acquired data is accurate and reliable, and the device can adapt to complex underground wireless environments, thereby realizing high-quality underground temperature monitoring.

In some embodiments, the temperature measurement host acquires feature data of various cables, service durations of the various cables and historical temperature data of the cables, trains a cable health assessment model according to the feature data, the service durations and the historical temperature data, acquires temperature data of a target cable through a temperature sensor after receiving a target cable service life checking instruction sent by a user terminal, inputs the temperature data and the feature data of the target cable into the cable health assessment model, acquires service life information of the target cable, and sends the service life information to the user terminal. Specifically, the temperature measuring host can extract characteristic data of different types of cables, such as material parameters, wire diameter parameters, rated current and the like, from a cable database of an electric power department; actual laying use time length data of different cables; and the temperature monitoring historical data collected by the cable in the using process. After the three types of data are obtained, a cable health assessment model training unit in the temperature measuring host machine uses the data and adopts a proper learning algorithm to train a cable health assessment model. The model can obtain the influence of the health state and the residual life of the cable through the characteristics of the cable, the using time and the historical temperature.

When a user needs to check the service life of a certain item of the cable, a target cable service life checking instruction can be sent to the temperature measuring host through the client, and the target cable service life checking instruction can comprise characteristic data of the target cable. The temperature measuring host can firstly acquire real-time temperature data of the cable through the temperature sensor of the area where the cable is located. The temperature data is then input into a pre-trained cable health assessment model along with the characteristic data of the target cable, which can assess the health of the cable and output its remaining useful life.

And finally, the temperature measurement host sends the service life information of the cable output by the model to the user side, so that the user can check the health state and the service life prediction result of the cable.

Therefore, the health state of the cable can be accurately monitored in an intelligent model evaluation mode, the service life of the cable can be predicted, and important support is provided for maintenance and planning of an electric power department.

In some embodiments, the signal line of the temperature sensor on the underground cable in the related art is complex, and once a certain temperature sensor fails, the signal line is difficult to quickly locate, and manual step-by-step investigation is required, which is time-consuming and labor-consuming. Even if a fault sensor is found, the fault sensor needs to be manually operated and repaired on site, and the fault sensor cannot be remotely commanded to be repaired. Manual monitoring is prone to inadvertent data, possibly missing the fault alarms of individual sensors. If the number of fault sensors in the area is large, the fault sensors are difficult to process manually at the same time, so that the maintenance is not timely. In this way, if a critical temperature sensor of a certain line fails but is not found and processed in time, a monitoring blind area can appear in temperature data of the area, and a cable can overheat or even fire in a certain narrow space, and then evolve into a power failure or fire accident, so that a great potential safety hazard is caused. By setting the serial number of the sensor and automatically judging the fault, the application can realize the automatic identification and positioning of the fault sensor, greatly shorten the fault response time and avoid serious consequences caused by missed detection. Meanwhile, maintenance instructions can be issued remotely, manual on-site operation is not needed, and maintenance efficiency and system reliability are improved fundamentally.

In connection with the above embodiments, a further more specific flow of the method provided in this embodiment will be described below. Referring to fig. 3, fig. 3 is another flow chart of a temperature monitoring method for an underground cable according to an embodiment of the application.

S301, determining a serial number set by each temperature sensor in the set range, wherein the serial number is a label bound with data information of the temperature sensor, and the data information comprises temperature data detected by the temperature sensor and position information of the temperature sensor;

In order to monitor the working state of each temperature sensor, a unique serial number can be set for each sensor in a set range in advance and is bound with the data information of each sensor.

The temperature measuring host can inquire the database and acquire the relevant information of all deployed temperature sensors within a set range. Each temperature sensor is allocated with a unique identification sequence number when deployed, and the sequence number is stored in a binding way with the temperature data collected by the temperature sensor, deployment position and other information. The temperature measuring host extracts all the sensor serial number information from the database, establishes the mapping relation between the temperature sensor and the corresponding serial number in the set range, and provides a basis for the subsequent state judgment.

For example, the monitoring range is set as a zone A, and the database stores information of 8 sensors in the zone, including the temperature sensor numbers (1-8) and position data. The temperature measuring host can extract the number information of the 8 sensors from the database, and confirm that 8 temperature sensors exist in the A area, and the number is 1 to 8 respectively. Thus, the determination of the serial number of the temperature sensor in the set range is completed.

S302, determining a sequence number set in the set range;

The serial number information of all the temperature sensors within the set range has been determined by the previous step. The step needs to summarize the sequence numbers to form a complete sequence number set within a set range.

The temperature measuring host machine collects all the sequence numbers of the temperature sensors obtained in the last step and gathers the sequence numbers to form a sequence number set {1,2,..8 } in the set range A. The sequence number set contains all the sequence number information of the temperature sensor in the zone A.

The purpose of forming the sequence number set is to provide a reference for the subsequent determination of the integrity of the data set. Only if the data of all serial numbers in the serial number set are collected, the fact that all sensor data in the area are normally collected can be explained.

S303, determining a collected sequence number set corresponding to the temperature data;

The temperature measuring host obtains a batch of temperature data through the identification processing of the wireless signals. These temperature data correspond to the serial number information of the temperature sensor.

The temperature measuring host analyzes the sequence number information corresponding to the temperature data, and gathers the sequence numbers of the successfully collected data to form a collected sequence number set, for example {1,3,5}.

By comparing with the set range sequence number set in the last step, the data of which sensors are successfully collected and the data of which sensors are not received can be judged. The more complete the collected sequence number set, the more adequate the sensor data acquisition within the area.

By determining and comparing different sequence number sets, a basis is provided for the integrity of the data set and the sensor state to be judged subsequently, and extraction and management of the sequence number sets are realized.

S304, determining an uncollected sequence number set according to the sequence number set and the collected sequence number set;

through the first two steps, a total sequence number set of the temperature sensor and a sequence number set of the successfully collected data in a set range are respectively obtained. The step needs to judge which data corresponding to the sequence numbers are not collected based on the two sets, namely determining that the sequence number sets are not collected.

The temperature measuring host compares the total sequence number set and the collected sequence number set one by one, eliminates the collected sequence number set from the total sequence number set according to the difference operation principle of the sets, and the rest is the uncollected sequence number set.

For example, the total sequence number set is {1,2,..8 }, the collected sequence number set is {1,3,5}, then the uncollected sequence number set is {2,4,6,7,8}.

By determining the difference set, the data of which sensors are not normally received can be clearly known, and a basis is provided for subsequent determination of the failure sensor and maintenance.

S305, determining the temperature sensor corresponding to the uncollected sequence number set as a failure temperature sensor;

after the collection of uncollected serial numbers is obtained, the temperature sensor corresponding to the serial numbers can be judged to be a failure temperature sensor. Because of the normal functioning sensor, its data should be able to be received.

And the temperature measuring host directly judges that the sensors identified by the serial numbers are the temperature sensors which are invalid at present according to the collection of the serial numbers.

In the above example, it can be determined that the temperature sensors with serial numbers 2, 4, 6, 7, 8 are currently out of order, cannot work normally, and need maintenance or replacement.

Through the serial number of quick location inefficacy temperature sensor, can improve temperature monitoring system's reliability, carry out the maintenance of pertinence.

S306, sending a maintenance instruction to the user side, wherein the maintenance instruction is used for prompting maintenance personnel to maintain the failure temperature sensor.

After obtaining the information of the failure sensor, a maintenance person needs to be notified to carry out maintenance. The temperature measuring host generates a corresponding maintenance instruction which comprises the serial number, the position and other information of the failure sensor, and the corresponding maintenance instruction is displayed through the user side to prompt maintenance operations of maintenance personnel.

For example, the maintenance instruction may be displayed as "temperature sensor 2 is out of order, position XX, please check replacement". After receiving the instruction, the maintenance personnel can take the standby temperature sensor to directly go to the designated position, replace the failure temperature sensor and restore the temperature monitoring function.

Therefore, through the automatically generated maintenance instruction, the maintenance efficiency can be greatly improved, so that the failure sensor can be repaired in the shortest time, and the normal operation of the system is ensured.

Therefore, the automatic identification and processing of the failure temperature sensor are realized, the problem sensor is directly found out through sequence number set judgment, then specific maintenance operation is guided, the manual one-by-one inspection inefficiency mode is avoided, and the intellectualization and automation level of the underground temperature monitoring system is greatly improved.

In some embodiments, the temperature measuring host may detect whether the temperature data is within a normal temperature interval, if the temperature data is outside the normal temperature interval, determine the temperature data outside the normal temperature interval as abnormal temperature data, and after determining an abnormal sequence number corresponding to the abnormal temperature data, determine alarm information according to the abnormal sequence number, where the alarm information includes location information corresponding to the abnormal sequence number and the abnormal temperature data. Specifically, after obtaining the temperature data, the temperature measuring host can detect whether the temperature data is within a normal temperature interval. The normal temperature interval can be set to a reasonable range according to the rated temperature of the cable and the ambient temperature, for example, 20-50 ℃, and can also be a range set by a manager. The temperature measuring host computer can check whether all the temperature data are in the normal temperature range of 20-50 ℃ one by one. If the temperature data acquired by the individual temperature sensors is found to be outside the normal temperature interval, the part of the temperature data is determined to be abnormal temperature data.

Furthermore, the temperature measuring host can lock the position of the abnormal temperature according to the serial number of the temperature sensor corresponding to the abnormal temperature data. Then, the organization forms alarm information, the alarm information comprises the value of abnormal temperature, the corresponding sensor serial number, position information and the like, and the alarm information is sent to monitoring personnel to prompt that the temperature abnormal condition exists at the position and needs to be processed.

Therefore, when the temperature of the cable is abnormal, the temperature measuring host can accurately position the problem position and give an alarm in time, so that managers can quickly respond and process faults, serious accidents are avoided, and the safety monitoring capability of the underground cable is improved.

In some embodiments, in the related art, a related person wants to view the distribution situation of the sensors in the area, and there is a trouble that the related person can only manually view the historical deployment record of the temperature sensor to determine whether the distribution is reasonable. The records are stored in a text, picture or data mode, and related personnel need to spend a great deal of time to check the consistency of the records with the on-site situation one by one. When a building is newly built in an area, related personnel cannot quickly judge whether the existing temperature sensor distribution meets the monitoring requirement or not, and complicated manual investigation and measurement are needed to be carried out again. The manual judgment is easy to be overlooked, so that the sensor distribution of certain areas is too sparse or too dense. Related personnel cannot intuitively grasp the distribution quality of the sensors in different areas, and a great amount of blindness exists in redeployment of the temperature sensors.

The distribution condition of the sensor is determined by automatically analyzing the serial numbers of the sensors, and areas with different densities are displayed, so that relevant personnel can see the distribution condition of the sensors at a glance. Meanwhile, the problem area can be identified rapidly through color labeling, so that the efficiency and quality of checking the distribution of the sensor are improved greatly, the difficulty of manual judgment is avoided, guidance is provided for redeployment of the sensor, and the method is very practical.

In connection with the above embodiments, a further more specific flow of the method provided in this embodiment will be described below. Referring to fig. 4, fig. 4 is another flow chart of a temperature monitoring method for an underground cable according to an embodiment of the application.

S401, after receiving a temperature sensor position checking instruction of a set range sent by a user side, determining all serial numbers and position information corresponding to the set range;

And a user can send a temperature sensor position checking instruction with a set range to a user side of the temperature measuring host according to the requirement, and the position information of the temperature sensor in the range is required to be acquired.

The temperature measuring host receives the instruction, and then queries a database according to the set area range to acquire the serial numbers and the corresponding position information of all the temperature sensors in the range.

For example, the user sets the viewing area to zone A, and 8 sensors of zone A are stored in the database, including sequence numbers 1-8 and location coordinates (x 1, y 1) through (x 8, y 8). The receiving unit extracts all serial numbers and position information of the 8 sensors from the database to form a complete corresponding relation between the serial numbers and the positions in a set range.

After all serial numbers and position information in the set range are obtained, a temperature sensor distribution overview of the area can be provided for a user, and basic data is provided for subsequent determination of sensor distribution conditions.

S402, determining position distribution information of a temperature sensor according to all the sequence numbers and the position information, wherein the position distribution information of the temperature sensor comprises a sequence number distribution dense region and a sequence number distribution sparse region, and the sequence number distribution dense region and the sequence number distribution sparse region are regions obtained by analyzing the position information of all the sequence numbers;

according to the serial numbers and the position information of all the temperature sensors in the set range obtained in the last step, the position distribution condition of the temperature sensors in the area can be analyzed and determined, and the area with dense serial number distribution and sparse serial number distribution can be judged.

The temperature measuring host can adopt a certain distribution analysis algorithm, such as cluster analysis and the like, to carry out statistical analysis on the position information of all serial numbers, determine the areas where the temperature sensors are more concentrated and sparser, and form the judgment results of the areas where the serial numbers are densely distributed and the areas where the serial numbers are sparsely distributed.

For example, after 8 sensors in the a area are analyzed, 3 sensors are gathered in the A1 area, and 5 sensors are distributed in the A2 area, it can be determined that the A1 area is a sequence number distribution dense area, and the A2 area is a sequence number distribution sparse area. This can intuitively reflect the sensor distribution of different areas.

In this way, it is assumed that a region A of the underground region is originally a region with sparse temperature sensor distribution, and only a small number of temperature monitoring points are arranged. Later, the area is constructed by newly building a market, and a large number of cables and equipment facilities are increased. However, when the manager checks the position distribution information of the temperature sensor, the distribution state of the area A is found to be sparse, which is not consistent with the actual situation.

At this point, the manager can appreciate that the original sensor distribution scheme needs to be optimally updated to accommodate the new monitoring needs due to changes in the environment and facilities within the area. Therefore, a manager can plan and increase a batch of sensors according to the actual layout of a newly built market in the area A, and densely arrange cable areas with higher loads in the market, electric rooms and other key areas so as to ensure that the cable loads and temperature changes of the new place can be monitored.

Meanwhile, the manager can pay attention to the update condition of the temperature sensor distribution monitoring, and after the sensor is deployed in the newly added mode, the temperature sensor position distribution information of the area A is checked again. If the sensor distribution state of the feedback area A of the monitoring system becomes dense, the newly added sensors are successfully deployed, so that the cable temperature in a newly built place can be fully monitored, a temperature monitoring blind area is prevented from being generated, and the service quality and the safety level are ensured.

Therefore, by combining with a newly-built place, the temperature monitoring system can continuously optimize the distribution scheme of the temperature sensor, adapt to the change of the regional environment and the monitoring requirement at any time, and keep the distribution rationality of the sensor, thereby improving the monitoring quality and the management level of the cable temperature.

S403, sending the position distribution information of the temperature sensor to the user side;

After the position distribution information of the temperature sensor in the set range is obtained, the temperature measurement host computer needs to send the position distribution information to the user terminal for reference of the user.

The temperature sensor position distribution information sending unit gathers the position distribution information of the sequence number distribution dense area and the sequence number distribution sparse area determined in the previous step and actively pushes the position distribution information to a user through a user terminal interface.

After receiving the information, the user can clearly know the position distribution condition of the sensor in the set range, and is convenient for the user to judge whether the sensors need to be added or reduced in different areas to optimize the monitoring quality.

This completes the determination and provision of the distribution of the temperature sensor positions within the specified range. The method adopts an active pushing mode to enable the user to obtain the position distribution information, avoids the trouble of manual inquiry statistics of the user, and improves the intelligent level of the positioning service.

In some embodiments, the color mark may be further added to the temperature data and sent to the user side in a visual form, specifically, after all the temperature data corresponding to the serial number are obtained, it is determined whether the temperature data is in a plurality of temperature intervals with set colors, where the temperature intervals with set colors are temperature data intervals corresponding to set colors: after the temperature data corresponding to all the temperature sensor serial numbers in the set range are obtained, the temperature values can be subjected to section judgment to see whether the temperature values are in the preset temperature intervals represented by different colors. The color temperature interval setting judging unit sets a plurality of color intervals according to different temperature numerical ranges, for example, the temperature is in a blue interval of 30-40 degrees, the temperature is in a yellow interval of 40-50 degrees, and the temperature is in a red interval of more than 50 degrees. After receiving all the temperature data, the judging unit judges which color interval each temperature value belongs to one by one, and provides basis for subsequent color marks. For example, if the acquired temperature data has 32 degrees, 41 degrees, and 55 degrees, the judging unit may determine that 32 degrees are in the blue interval, 41 degrees are in the yellow interval, and 55 degrees are in the red interval according to the set color interval. Thus, the mapping relation between the temperature data and the color interval is completed.

After the temperature data is determined to be in the set target color temperature interval, marking the position information corresponding to the temperature data with a target color: and judging the temperature interval in the last step to obtain the color corresponding to each temperature data. This step requires labeling the temperature data locations in the target color interval. The thermometric host may select a red interval based on the target color interval, for example. And then, marking the position information corresponding to the temperature data belonging to the red interval in the judging result with red. In the above example, if 55 degrees is within the red interval, the target color is red, and the position (x 5, y 5) corresponding to the 55 degrees temperature data is marked with red. Thus, color labeling of key temperature positions is realized.

Determining final temperature sensor position distribution information in combination with the target color mark: the temperature conditions of different positions are fully reflected through the color marks. The final position distribution information of the temperature sensor is determined by combining the color marking result. The temperature measuring host blends the color mark result based on the first position distribution information to generate final position distribution information of the temperature sensor. Such as determining the location of the red mark as a distribution hot spot area. Therefore, when a user views the position distribution information, the user can intuitively see the distribution of the area with higher temperature through the color, so that the overheat prevention condition of the area can be conveniently judged, and the information can be intuitively displayed.

The embodiment realizes the separation of the temperature in the position distribution through the multiple color marks, so that a user can clearly see the layout of different temperature areas at a glance, the area monitoring quality and the overheat analysis prevention are assisted, and the visual effect and the comprehensiveness of the temperature monitoring are improved.

In some embodiments, the areas with dense sequence numbers and sparse sequence numbers can be combined with color marks, specifically, the areas with dense sequence numbers and sparse sequence numbers are judged through a certain distribution analysis algorithm according to the sequence numbers and the position data of the temperature sensor. And labeling the concentrated areas and the sparse areas which are obtained by analysis on the position distribution map, wherein the concentrated areas can be marked green, and the sparse areas can be marked white. And then acquiring real-time temperature data corresponding to each serial number. Temperature grading is performed using different colors according to temperature values, for example:

30-40 degree mark as blue

The mark with the color of yellow at 40-50 DEG

More than 50 degrees marked as red

And covering the positions of the temperature sensors by using different colors on the position distribution map, determining the colors according to the real-time temperature data of each sensor, and finally determining the position distribution map of the temperature sensors, wherein the serial number distribution areas are marked by different colors, and the temperature values are marked by dots with different colors.

Therefore, through combining sequence number distribution and temperature color labeling, a user can intuitively see the distribution and real-time temperature condition of each region, so that dense sparse distribution is clear, high-temperature distribution regions are also clear, and effective fusion of position and temperature information is realized.
