Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before describing the embodiments of the present disclosure in detail, the following description is first made on the application scenario of the present disclosure, and the present disclosure may be applied to a life body monitoring process, for example, a scenario in which whether a passenger climbs a platform door or is in a dangerous area is monitored in a semi-closed platform in rail transit, or a scenario in which whether a visitor enters a prohibited area is monitored in a scenic spot. Here, it is described by taking an example of monitoring whether a passenger climbs over a platform door or is in a dangerous area, a semi-closed waiting platform is generally a semi-high platform of about 1.5 meters arranged between a train travelling area and the waiting platform, the train travelling area is separated from the waiting platform by the semi-high platform, and since there is no isolation facility in a part of 1.5 meters above the semi-high platform, an illegal behavior of climbing over the platform often occurs, and the illegal behavior has a serious safety hazard. In the current half-height platform operation mode, in order to eliminate potential safety hazards existing in the half-height platform, a specially-assigned person is generally dispatched to carry out on-site inspection, or the specially-assigned person is dispatched to check whether a person or a pet and other life bodies have the potential safety hazards in a mode of watching monitoring videos, and under the condition that the potential safety hazards exist, a passenger is reminded not to approach the half-height platform and not to climb over the platform. That is to say, the existing platform monitoring mode has strong dependence on manual work, and can not effectively save labor cost, and because the instability of manual monitoring easily results in that individual dangerous life bodies with potential safety hazards are not found, the problems of low monitoring and identifying rate and poor reliability also exist.
In order to solve the above technical problems, the present disclosure provides a platform monitoring system and method, which obtains a life detection signal in a preset platform monitoring space; under the condition of acquiring the life detection signal, determining whether a dangerous life body exists in the platform monitoring space according to the life detection signal; determining a target area where the dangerous living body is located under the condition that the dangerous living body exists in the platform monitoring space; determining a target danger level corresponding to the dangerous life object according to the target area; and executing an alarm strategy matched with the target danger level according to the target danger level. The automation degree of platform monitoring can be improved, the recognition rate of dangerous life bodies is improved, different alarm strategies can be executed aiming at the dangerous life bodies with different danger levels, and therefore the occurrence probability of safety accidents can be effectively reduced.
Fig. 1 is a schematic diagram of a station monitoring system according to an exemplary embodiment of the present disclosure; referring to fig. 1, the system includes: a controller 101, and a monitoring component 102 and an alarm device 103 connected with the controller 101;
the monitoring component 102 is configured to obtain a life detection signal in a preset platform monitoring space;
the controller 101 is configured to determine whether a dangerous life exists in the platform monitoring space according to the life detection signal when the monitoring component acquires the life detection signal, determine a target area where the dangerous life exists when it is determined that the dangerous life exists in the platform monitoring space, determine a target danger level corresponding to the dangerous life according to the target area, and send a control instruction to the alarm device according to the target danger level, where the control instruction is used to control the alarm device to execute an alarm policy matched with the target danger level;
the alarm device 103 is configured to execute an alarm policy corresponding to the target risk level according to the control instruction.
The monitoring assembly 102 may include a plurality of infrared sensors 1021, different ones of the infrared sensors 1021 being configured to obtain life detection signals for different areas of the platform monitoring space.
It should be noted that a plurality of the infrared sensors 1021 may be distributed on the platform ground according to a predetermined distribution rule, where the distribution rule may be: dividing the platform ground corresponding to the platform monitoring space into a grid, and distributing a plurality of infrared sensors 1021 at the intersections of the grid (as shown in fig. 2a, fig. 2a is a schematic distribution diagram of the infrared sensors according to an exemplary embodiment of the present disclosure); or, the infrared sensors may be distributed on a plurality of target straight lines parallel to the plane of the platform door, where each target straight line has one infrared sensor 1021 at every preset distribution distance, the preset distribution distances corresponding to two adjacent infrared sensors 1021 on different target straight lines may be different, and the separation distance between every two adjacent target straight lines in the plurality of target straight lines may be different (as shown in fig. 2b, fig. 2b is a schematic distribution diagram of infrared sensors according to another exemplary embodiment of the present disclosure); or, the plurality of infrared sensors are distributed into a preset warning identification pattern (for example, in the shape of an exclamation mark), and the infrared sensors distributed in the preset warning identification pattern can acquire life detection signals in respective monitoring areas and improve the attractiveness of the platform.
In addition, an angle a of infrared radiation of each infrared sensor 1021 may be in a range of 30 ° to 45 °, and a monitoring area corresponding to each infrared sensor 1021 is an area range that can be irradiated by infrared rays in the infrared sensor, as shown in fig. 2c (fig. 2c is a schematic diagram of an operating principle of a monitoring assembly shown in an exemplary embodiment of the present disclosure), when an interval between two adjacent infrared sensors 1021 is relatively close, a monitoring area of the adjacent infrared sensor 1021 may have a coincidence area, when an interval between two infrared sensors 1021 is relatively far, a monitoring area of the adjacent infrared sensor 1021 does not have a coincidence area, and a spacing distance between the adjacent infrared sensors may be adjusted according to a monitoring requirement, which is not limited by the present disclosure.
According to the technical scheme, whether the dangerous life bodies exist in the platform monitoring space can be determined according to the life detection signals, the target danger levels corresponding to the dangerous life bodies are determined under the condition that the dangerous life bodies exist in the platform monitoring space, the alarm strategies matched with the target danger levels are executed according to the target danger levels, the automation degree of platform monitoring can be improved, the identification rate of the dangerous life bodies is improved, different alarm strategies can be executed according to the dangerous life bodies with different danger levels, and therefore the occurrence probability of safety accidents can be effectively reduced.
Optionally, the controller 101 is further configured to:
acquiring the time length of the life detection signal which is continuously detected; when the time length is greater than or equal to a preset time threshold, determining that the dangerous life body exists; and when the time length is smaller than the preset time threshold, determining that the dangerous life body does not exist.
In one embodiment, the time duration may be a duration of a life detection signal corresponding to a current living entity in the platform monitoring space, and when the time duration that the current living entity appears in the platform monitoring space is greater than or equal to a preset time threshold, it is determined that the current living entity is a dangerous living entity, that is, the dangerous living entity exists in the platform monitoring space; when the time length of the current life body appearing in the platform monitoring space is smaller than a preset time threshold, determining that the current life body is a non-dangerous life body, namely, the platform prediction space does not have the dangerous life body; for example, the duration of time for which the first infrared sensor acquires the life detection signal corresponding to the passenger a is 10 seconds, and then the duration of time for which the second infrared sensor acquires the life detection signal corresponding to the passenger a is 5 seconds, that is, after the passenger a waits for 10 seconds in the first monitoring area in the platform monitoring space, the passenger a moves to the second monitoring area in the platform monitoring space, and the time for which the passenger a stays in the second monitoring area is 5 seconds, so that the time length of the passenger a in the platform monitoring space is 15 seconds. Therefore, the time length of staying in the platform monitoring space is calculated independently for each passenger entering the platform monitoring space, so that whether each passenger entering the platform monitoring space is a dangerous life body or not is determined, and the recognition rate of the dangerous life body can be effectively improved.
In another embodiment, the time length may be a time during which the living body is always present in the platform monitoring space, for example, the time length is 25 seconds when passenger a waits for 15 seconds in the platform monitoring space, passenger B enters the platform monitoring space within 15 seconds of passenger a waiting, and passenger B still stays in the platform monitoring space for 10 seconds after passenger a leaves the platform monitoring space. Therefore, whether dangerous life bodies exist or not is determined according to the total time of the plurality of life bodies staying in the platform monitoring space, the phenomenon that too many passengers enter the platform monitoring space in a short time but danger reminding cannot be carried out can be avoided, and the reliability of the platform monitoring system can be effectively improved.
Optionally, the monitoring component 102 includes a plurality of infrared sensors 1021, different ones of the infrared sensors 1021 being configured to obtain life detection signals of different areas within the platform monitoring space and send the life detection signals to the controller 101;
the controller 101 is configured to, when receiving the life detection signal, obtain a target identifier of a target infrared sensor that sends the life detection signal, determine a target detection area corresponding to the target infrared sensor according to the target identifier, determine the target detection area as the target area where the dangerous living body is located, determine a target distance between the target area and a plane where the platform door is located, and determine a current target risk level of the dangerous living body according to the target distance.
Embodiments of determining the target distance between the target area and the plane of the platform door may include the following two types:
one, obtain the target location nearest to the plane of the platform door in the target area; determining the distance between the target position and the plane of the platform door as the target distance between the target area and the plane of the platform door.
Another is that after the infrared sensors are installed, the target detection area corresponding to each infrared sensor is fixed, that is, the target distance between the target area and the plane where the platform door is located is a fixed value, so that the target distance between each target area and the plane where the platform door is located can be stored in the system in advance, and after the target area is determined in the use process, the target distance corresponding to the target area can be directly called, so as to reduce the use of obtaining the target distance, improve the speed of determining the target danger level corresponding to the dangerous body, thereby improving the detection efficiency of the platform monitoring system and reducing the occurrence probability of safety accidents.
For example, after the passenger C enters the platform monitoring space, the infrared sensor with the number (x, y) acquires the life detection signal corresponding to the passenger C, and sends the life detection signal corresponding to the passenger C to the controller 101, after the controller 101 receives the life detection signal corresponding to the passenger C, the number (x, y) of the infrared sensor that acquires the life detection signal corresponding to the passenger C is determined, the target detection area (area a) corresponding to the infrared sensor with the number (x, y) is determined according to the number (x, y), which indicates that the passenger C is currently located in the area a, and the target distance between the area a and the plane where the platform door is located can be obtained. In the station monitoring system, the correspondence between the number (x, y) and the target detection area (area a) is stored in advance, and when the number (x, y) is determined, the target detection area (area a) corresponding to the number (x, y) can be acquired.
When a plurality of infrared sensors simultaneously detect life detection signals, the number of the infrared sensor corresponding to each life detection signal is acquired, the detection area corresponding to the infrared sensor of each number is acquired, a target detection area closest to the plane where the platform door is located is determined from the plurality of detection areas, and the distance between the target detection area and the plane where the platform door is located is determined as the target distance. In the platform monitoring system, a target detection area corresponding to each numbered infrared sensor is stored in advance.
Optionally, the controller 101 is further configured to:
determining that the current target risk level of the dangerous life object is a high-level risk level under the condition that the target distance is smaller than or equal to a first distance threshold;
determining that the current target risk level of the dangerous life object is a medium risk level under the condition that the target distance is greater than the first distance threshold and smaller than a second distance threshold;
and determining the current target risk level of the dangerous life object as a primary risk level under the condition that the target distance is greater than or equal to the second distance threshold.
Wherein, the first distance threshold is smaller than the second distance threshold, and the smaller the target distance is, the smaller the distance between the dangerous life body and the plane where the platform door is located is, the higher the danger level corresponding to the dangerous life body is currently.
It should be noted that, when the target danger level is determined to be the high-level danger level, the photoelectric generator in the alarm device is controlled to generate a photoelectric warning signal, and the dangerous living body is prompted to leave the platform monitoring space through the photoelectric warning signal. When the target danger level is determined to be the intermediate danger level, the alarm device can be controlled to play audio information in a broadcast mode, and the audio information can be pre-recorded warning voice; when the danger level is determined to be the primary danger level, the alarm device can be controlled to give a light alarm, and preset text prompt information and/or image prompt information are output while the light alarm is given.
Optionally, the system further comprises a temperature sensor 104, the monitoring assembly further comprises an electromagnetic wave detector 1022,
the temperature sensor 104 is used for detecting the current ambient temperature;
the electromagnetic wave detector 1022 is configured to obtain the life detection signal and a target area where a living body corresponding to the life detection signal is located in an electromagnetic wave manner;
the controller 101 is further configured to obtain the life detection signal and a target area where a corresponding living object is located in the platform monitoring space through the electromagnetic wave detector 1022 when the ambient temperature is greater than or equal to a preset temperature threshold; when the ambient temperature is less than the preset temperature threshold, the life detection signal in the platform monitoring space is acquired through the infrared sensor 1021.
It should be noted that, since the infrared sensor 1021 may obtain the life detection signal affected by the surface temperature of the object, the temperature of the human body is usually between 34 ℃ and 40 ℃, and in a high-temperature environment, the ambient temperature easily falls between 34 ℃ and 40 ℃, in order to improve the reliability of the monitoring result corresponding to the platform monitoring system, when the ambient temperature is greater than or equal to a preset temperature threshold (for example, may be 34 ℃), the life detection signal in the platform monitoring space and the target area where the life body corresponding to the life detection signal is located may be obtained through an electromagnetic wave detector (for example, a radar). Therefore, the accuracy of the monitoring result of the platform monitoring system in a high-temperature environment can be effectively improved, and the reliability of the platform monitoring system can be improved.
According to the technical scheme, whether the dangerous life bodies exist in the platform monitoring space can be determined according to the life detection signals, the target danger levels corresponding to the dangerous life bodies are determined under the condition that the dangerous life bodies exist in the platform monitoring space, the alarm strategies matched with the target danger levels are executed according to the target danger levels, the automation degree of platform monitoring can be improved, the identification rate of the dangerous life bodies is improved, different alarm strategies can be executed according to the dangerous life bodies with different danger levels, and therefore the occurrence probability of safety accidents can be effectively reduced.
Fig. 3 is a flowchart illustrating a method for station monitoring according to an exemplary embodiment of the present disclosure; referring to fig. 3, the method applied to the station monitoring system may include the following steps:
The platform monitoring space can be a preset space area close to a platform door in a platform, a monitoring assembly is arranged on the platform ground corresponding to the platform monitoring space, and the platform monitoring space is formed by the monitoring area corresponding to the monitoring assembly. The monitoring assembly may comprise a plurality of infrared sensors or at least one electromagnetic wave detector.
It should be noted that the platform monitoring system may further include a temperature sensor, which is configured to detect a current ambient temperature; the electromagnetic wave detector is used for acquiring the life detection signal and a target area where a life body corresponding to the life detection signal is located in an electromagnetic wave mode.

In step 302, under the condition that the life detection signal is obtained, whether a dangerous life object exists in the platform monitoring space is determined according to the life detection signal.
In this step, the time length for which the life detection signal is continuously detected may be acquired; when the time length is greater than or equal to a preset time threshold, determining that the dangerous life body exists; and when the time length is smaller than the preset time threshold, determining that the dangerous life body does not exist.
It should be noted that, in one embodiment, the time duration may be a time duration of the life detection signal corresponding to the current living entity in the platform monitoring space, and when the time duration of the current living entity appearing in the platform monitoring space is greater than or equal to a preset time threshold, it is determined that the current living entity is a dangerous living entity, that is, the platform prediction space has the dangerous living entity; when the time length of the current life body appearing in the platform monitoring space is smaller than a preset time threshold, determining that the current life body is a non-dangerous life body, namely the platform monitoring space does not have the dangerous life body; in another embodiment, the time length may be a time when the living body is always present in the station monitoring space.

and according to a third distribution rule, a plurality of infrared sensors are distributed into a preset warning identification pattern.
One possible implementation of the steps is: under the condition of receiving the life detection signal, acquiring a target identifier of a target infrared sensor which sends the life detection signal; determining a target detection area corresponding to the target infrared sensor according to the target identification; and determining the target detection area as the target area where the dangerous life body is located.
And step 304, determining a target danger level corresponding to the dangerous life object according to the target area.
One possible implementation is as follows: determining the target distance between the target area and the plane of the platform door; and determining the current target danger level of the dangerous life body according to the target distance.
Another possible implementation is: the target distance between each target area and the plane where the platform door is located is stored in the system in advance, and after the target area is determined in the using process, the target distance corresponding to the target area can be directly called, and the current target danger level of the dangerous life body is determined according to the target distance.
It should be noted that the determining the current target risk level of the dangerous living being according to the target distance may include: determining that the current target risk level of the dangerous life object is a high-level risk level under the condition that the target distance is smaller than or equal to a first distance threshold; determining that the current target risk level of the dangerous life object is a medium risk level under the condition that the target distance is greater than the first distance threshold and smaller than a second distance threshold; and determining the current target risk level of the dangerous life object as a primary risk level under the condition that the target distance is greater than or equal to the second distance threshold.
And 305, executing an alarm strategy matched with the target danger level according to the target danger level.
It should be noted that, when the target danger level is determined to be the high-level danger level, the photoelectric generator in the alarm device is controlled to generate a photoelectric warning signal, and the dangerous living body is prompted to leave the platform monitoring space through the photoelectric warning signal. When the target danger level is determined to be the intermediate danger level, the alarm device can be controlled to play audio information in a broadcast mode, and the audio information can be pre-recorded warning voice; when the danger level is determined to be the primary danger level, the alarm device can be controlled to give a light alarm, and preset text prompt information and/or image prompt information are output while the light alarm is given.
