Technical Field

The present application relates to the field of elevator management technologies, and in particular, to an elevator control method, an elevator control device, and a storage medium.

Background

An elevator refers to a permanent transport device serving a number of specific floors within a building with its car running in at least two columns of rigid rails running perpendicular to the horizontal or inclined at an angle of less than 15 ° to the plumb line. Elevators are an indispensable equipment for a high-rise building and a highly utilized public transportation means.

Along with the popularization of elevators in life of people, people can conveniently come and go on high floors, and safety hazards are brought to the other hand, for example, electric bicycles are favored by people because of the advantages of moderate cost, high running speed, labor saving, economy, good use and the like, but news of fire caused by unsafe use of the electric bicycles are frequently reported, the reasons for the reasons are partly due to unqualified product quality and partly due to improper use of users, potential risks that electric bicycles are brought back to home by owners through the elevators are huge, and huge personnel and property losses can be caused by fire caused by charging in residential buildings, especially the consequences caused by high-rise building fire are serious.

Referring to fig. 2, fig. 2 is a schematic flow chart of an elevator control method according to an embodiment of the present application, wherein the elevator control method may be implemented based on a control module in the schematic system architecture shown in fig. 1, but may also be implemented based on other architectures, and the method includes, but is not limited to, the following steps:

Step S201: and the camera module is used for determining that an electric vehicle is placed in the elevator cabin.

Specifically, firstly, receiving image information captured by the camera module; matching current item information from a preset item database according to the current image information;

The current article information includes names, weights, body shapes, functions and the like of articles, when the names of the articles are "electric vehicles", the articles are electric vehicles, namely, the possibility of the electric vehicles exists, and the preset article database is as follows: a plurality of articles which are actually existing and are easy to use by a user and carry, particularly electric vehicles, are photographed and stored in advance, and the articles which are not recorded into the article database are added and updated in later use; alternatively, the identified program may identify through hundred degree identification or google identification, and the picture data of the identification may be photographed by a worker.

In an alternative embodiment, the sensor module and the camera module determine that the electric vehicle is placed in the elevator cabin, which is specifically as follows:

Acquiring weight information in the elevator cabin through the sensor module, wherein the weight information comprises weight distribution information, and the weight distribution information is used for representing the distribution of articles and personnel in the elevator cabin and the corresponding weight;

Evaluating the possibility of placing an electric vehicle in the elevator cabin according to the weight information; the possibility can be determined according to a weight distribution interval and a distribution area of the electric vehicle, wherein the weight distribution of the electric vehicle is generally a contact surface of a wheel and the ground and a contact point of a bracket and the ground, and the mass of the electric vehicle is relatively fixed, so that when partial information exists in the weight distribution information, the closer the weight distribution information is to the weight distribution information and the weight size of the electric vehicle, the higher the possibility is;

and under the condition that the possibility exceeds a preset fourth threshold value, capturing the picture information in the elevator through the camera module, and further determining whether the electric vehicle exists in the picture information.

In the embodiment of the application, compared with the information acquired by the camera module, the information acquired by the sensor module occupies smaller storage space, so that the information is preferentially acquired by the sensor module, long-time screening is performed, and when a result with a certain possibility is obtained, the camera module performs picture analysis, so that whether the result is an electric vehicle or not is determined, and the storage space is saved.

In an alternative embodiment, a plurality of cameras arranged in each floor layer and facing the elevator door position are used for acquiring images of the current elevator area corresponding to the elevator stopping floor so as to prompt passengers who want to bear the electric vehicle by the elevator not to push the electric vehicle into the elevator, and the method is specifically as follows:

and acquiring current image detection information of a current elevator area corresponding to the elevator stop floor.

The current elevator area is within a reasonable range from the inside of the elevator and the elevator door to the front of the elevator door, the reasonable range in front of the elevator door is generally based on the distance between the wall opposite to the elevator door and the elevator door, the range in the width direction is the width of each electric car on the left and right sides of the center of the elevator door, if no wall is used as an obstacle in front of the elevator door, the length of one electric car on the front of the elevator door is used as an example, namely, only the area needing the elevator door can accommodate the next electric car and a plurality of people and is not larger than the load range where the elevator can take, and a proper distance range is selected, so that the electric car is common knowledge of people in the field and is not repeated herein.

The current image detection information is photographed by a camera in the current elevator area, and the camera covers the periphery of an elevator opening and the up-down direction, so that an image with wider coverage is obtained, and the image content is more real and comprehensive.

Step S202: and if the fact that the power supply loop of the commercial power network for the elevator is disconnected is detected, the gravity power generation module is used for supplying power to the elevator.

Optionally, under the condition that the utility power network is not disconnected and aims at the power supply of the elevator, the gravity power generation module and the utility power network jointly supply power to the elevator control system, when a power supply passage of the utility power is disconnected, the gravity power generation module can also keep the power supply to the control module, so that the control module is in a working state, an emergency braking function when the elevator is triggered to be powered off is avoided, personnel in the elevator collide with the electric vehicle, and further, the possibility of occurrence of an spontaneous combustion event of the electric vehicle caused by the collision is reduced.

Step S203: and determining the fire risk level of the electric vehicle in the elevator cabin through the camera module and the sensor module.

It should be noted that, there are many reasons for spontaneous combustion or ignition of the electric vehicle, such as circuit modification, overcharge, high temperature and oxygen, and uneven temperature distribution of the battery, and these factors may cause the electric vehicle to ignite when not charged, so the ignition risk level is related to the reason for ignition of the electric vehicle when not charged, please refer to fig. 3, fig. 3 is a flow chart of a method for determining ignition risk level according to an embodiment of the present application, which specifically includes:

step S301: and determining the related information of the electric vehicle through the camera module and the sensor module.

The related information comprises an electric vehicle model, a battery type corresponding to the electric vehicle model and external characteristics corresponding to the electric vehicle model, wherein the external characteristics comprise a vehicle lamp model, an electric vehicle battery external characteristic and a charger type,

The control module can determine the related information through one or more connected databases, and the databases store information related to electric vehicles such as brands, types, appearance characteristics, battery models, charger models and the like of the electric vehicles on the current market.

The type of the electric vehicle can be determined according to the external characteristics of the electric vehicle in the picture information captured by the camera module, further, the type of the battery of the electric vehicle can be determined according to the type of the electric vehicle, and the part of the battery type of the electric vehicle is determined because the electric vehicle of a part of the types belongs to a naked state and is generally placed under a saddle, and the naked state of the battery is easier to cause the battery to have the events of water inflow, collision and the like in the daily use process, so that the risk of fire is increased; still another part of the reason is that some people will modify the battery of the electric vehicle after purchasing the electric vehicle in order to pursue a larger battery capacity, which modification is often accompanied by a risk, and thus, whether the type of the battery is consistent with the original factory can be determined by the infrared sensor in the sensor module.

The external characteristics are mainly used for distinguishing whether the circuit of the electric vehicle is consistent with the state of the electric vehicle when the electric vehicle leaves a factory, a plurality of people in the market can reform the electric vehicle after buying the electric vehicle, for example, a plurality of takeaway riders reform the lamps of the electric vehicle to pursue higher brightness, but the reform is likely to cause the problem of the circuit or the battery of the electric vehicle, and one important reason of spontaneous combustion of the electric vehicle is that the circuit/battery is short-circuited, so that whether the electric vehicle has a reform trace is determined by acquiring the lamp patterns in the external characteristics of the electric vehicle and the external characteristics of the battery of the electric vehicle, the reform trace comprises lamp reform and battery line reform, and the battery line reform corresponds to the external characteristics of the battery;

The charger type of the electric vehicle is mainly determined to judge whether the charger of the electric vehicle is an original charger, and one reason for causing spontaneous combustion of the electric vehicle is that the electric vehicle is charged by using a non-original charger, and the battery is possibly overcharged, the temperature is increased and spontaneous combustion is caused due to different rated voltage and current.

Step S302: and determining a first abnormal state of the electric vehicle according to the related information.

The first abnormal state includes a lamp retrofit, a visible portion circuit retrofit or a charger non-original.

Specifically, according to the lamp patterns in the external features corresponding to the type of the electric vehicle in the related information, the lamp patterns are compared with the prestored lamp patterns of the electric vehicle with the same type, and whether the electric vehicle is transformed or not can be determined;

The specific mode of determining whether the electric vehicle has visible partial circuit modification according to the battery type corresponding to the electric vehicle type number and the external characteristics of the electric vehicle battery in the related information can be the same as the method for determining the modification of the vehicle lamp, and the mode of determining whether the charger of the electric vehicle is an original charger is similar to the above process.

When an abnormal state is not found in any electric vehicle, the first abnormal state of the electric vehicle is empty.

Step S303: and determining the fire risk level of the electric vehicle according to the first abnormal state.

In the embodiment of the application, the fire risk level comprises a first-level fire risk, a second-level fire risk and a third-level fire risk;

The fire risk level is related to the first abnormal state of the electric vehicle, if the first abnormal state of the electric vehicle is empty, the fire risk level of the electric vehicle is also empty, and the specific determination mode can be shown in the following table:

the tables with primary fire risk are: the first abnormal state comprises a first electric vehicle transformed by the vehicle lamp, and the first abnormal state comprises a third electric vehicle with a non-original charger;

The risk of secondary fires is: the first abnormal state comprises a second electric vehicle with a visible part of the circuit modified, the first abnormal state comprises a fourth electric vehicle with a lamp modified and a visible part of the circuit modified, the first abnormal state comprises a fifth electric vehicle with a lamp modified and a charger not original, and the first abnormal state comprises a sixth electric vehicle with a visible part of the circuit modified and a charger not original;

The risk of having a three-stage fire is: the first abnormal state includes a seventh electric vehicle with lamp retrofit, visible portion circuit retrofit, and a charger not original.

Briefly, the more abnormal states included in the first abnormal state, the higher the corresponding fire risk level.

Referring to fig. 4, fig. 4 is a flowchart of another method for determining a fire risk level according to an embodiment of the present application, which is specifically as follows:

step S401: and detecting the temperature in the elevator through the sensor module.

Step S402: and detecting the battery temperature distribution condition of the electric vehicle through the camera module and the sensor module.

The camera module is mainly used for capturing characteristics of the battery, such as smoke, thermal melting characteristics and the like, which are related to the temperature.

The sensor module is used for determining the temperature distribution condition of the battery of the electric vehicle mainly through sensors such as a temperature sensor and a pressure sensor.

Optionally, the external temperature-related characteristic of the battery captured by the camera module is mainly used for proving the battery temperature distribution.

Step S403: and determining a second abnormal state of the electric vehicle according to the temperature in the elevator and the battery temperature distribution condition of the electric vehicle.

The second abnormal state includes uneven temperature distribution in the battery, which may cause uneven lithium precipitation in the battery and its mechanism, particularly in the lithium battery, which also represents a high possibility of spontaneous combustion.

The second abnormal state is mainly used for representing the abnormality of the battery inside of the electric vehicle.

If the temperature distribution in the battery is different from the temperature distribution of the battery in the normal state, the battery is represented to have a second abnormal state with uneven temperature distribution.

Step S404: and under the condition that the temperature in the elevator is higher than a preset third threshold value, determining the fire risk level of the electric vehicle according to the second abnormal state.

Since one of factors causing spontaneous combustion of the electric vehicle is also higher in external temperature, when the temperature in the elevator is higher than a preset third threshold (preferably 35 ℃), determining the fire risk level of the electric vehicle according to the second abnormal state, wherein if the temperature in the elevator is higher than the preset third threshold and the second abnormal state is empty, the fire risk level of the electric vehicle is first-grade, and if the temperature in the elevator is higher than the preset third threshold and the second abnormal state is uneven in temperature distribution, the fire risk level of the electric vehicle is second-grade.

In another alternative embodiment, the method for determining the fire risk level illustrated in fig. 3 and 4 may be used in combination, to further improve accuracy, for example, first determining the fire risk level of the electric vehicle through a first abnormal state; and secondly, correcting the fire risk level through the second abnormal state, for example, determining that the fire risk level of the electric vehicle is first level according to the first abnormal state, and adjusting the fire risk level of the electric vehicle from first level to second level if the second abnormal state is not empty.

Step S204: and generating a target algorithm corresponding to the fire risk level.

Step S205: and executing the target algorithm.

It should be noted that during execution of the target algorithm, it is possible that the elevator stays between floors due to emergency braking and the elevator door cannot be opened, so that the elevator position may be obtained first before the target algorithm is executed or when the "normally open elevator door" in the target algorithm is executed;

Step S206: if the fact that the power supply loop of the commercial power network is not disconnected with respect to the elevator is detected, whether the electric vehicle in the elevator fires or not is determined through the camera module and the sensor module.

Specifically, the temperature rising speed and the concentration of harmful gas in the elevator are detected through the sensor module; the temperature rising speed is the temperature rising speed of the internal space of the elevator or the temperature rising speed of the battery of the electric vehicle;

Acquiring a monitoring picture in the elevator through the camera module when the temperature rising speed is greater than a preset fourth threshold value and/or the concentration of the harmful gas is greater than a preset fifth threshold value; it should be noted that, if the temperature rising speed is the temperature rising speed of the battery of the electric vehicle, the preset fourth threshold may be set according to the test data of spontaneous combustion of the battery, for example, after the electric vehicle is tested, after 30 seconds from the initiation of the spontaneous combustion process, the flame temperature may rise to 310 ℃, after 2 minutes, the flame temperature reaches 680 ℃, after 3 minutes and 30 seconds, the whole electric bicycle will be wrapped by flame, and the temperature may reach 1200 ℃, where the temperature refers to the temperature inside the battery of the electric vehicle; if the temperature rise rate is the temperature rise rate of the elevator interior space, it can also be determined from the outside temperature in the above-mentioned test data.

Analyzing picture characteristics of the monitoring picture; the monitoring picture is captured by the camera module;

Step S207: and executing a fire extinguishing protection algorithm under the condition that the electric vehicle is determined to be on fire.

The fire-extinguishing protection algorithm comprises the steps of controlling a fire-extinguishing device at the top of a car of the elevator to extinguish fire towards a fire place of the electric car, and controlling a fire-extinguishing material storage device stored at the top of the car to be opened so as to throw fire-extinguishing materials to passengers in the elevator cabin.

Optionally, the fire protection algorithm comprises a fan that turns on the top of the elevator at maximum power.

In an alternative embodiment, while executing the fire protection algorithm, it may be determined whether to open the elevator door based on the current position of the elevator, as follows:

acquiring the elevator position;

Further, because the space in the elevator is narrow, smoke burned after the electric vehicle fires can be filled in the elevator, so that passengers cannot find an escape route in time, after the door is opened, the relative position of the electric vehicle and the passengers can be determined along with the image of the camera module, when the passengers are informed of escaping, the escape route is broadcasted to the passengers with the escape route blocked by the electric vehicle, for example, the electric vehicle is transversely placed at an elevator doorway, other passengers are behind the elevator, at the moment, the passengers at the rear can be informed of the direction from which the passengers can leave, damage can be reduced, and please refer to fig. 5, which is a flow diagram of a method for generating the escape route, provided by the embodiment of the application, specifically, the method comprises the following steps:

Step S501: and determining the position of the passenger in the elevator and the position of the electric vehicle according to the camera module and the sensor module.

Step S502: a smoke concentration and a local temperature within the elevator car are determined.

The local temperature is used to characterize the temperature in the elevator above the temperature of the area of the human body bearing range.

Step S503: and generating an escape route according to the smoke concentration, the local temperature, the position of the passenger and the position of the electric vehicle so that the passenger avoids a space with the smoke concentration higher than a preset first threshold value and the local temperature higher than a preset second threshold value and leaves the elevator.
