Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of automatic control, in particular, to a platform monitoring system and method. BACKGROUND

[0002] Generally, in order to ensure the safety of passengers waiting, a fully enclosed or semi-enclosed waiting platform is set up at the waiting site of rail transit (such as subway, monorail train, train, etc.) to improve the comfort of passengers waiting. Generally, a fully enclosed waiting platform can completely isolate the train running area from the passenger waiting area, and the probability of unsafe accidents is small. A semi-enclosed waiting platform is usually a semi-high platform of about 1.5 meters set between the train running area and the waiting platform, which separates the train running area from the waiting platform through the semi-high platform. Since the part of the semi-high platform above 1.5 meters does not have isolation facilities, there are often uncivilized behaviors of climbing over the semi-high platform, which poses a serious safety hazard.

[0003] In the current semi-high platform operation mode, in order to eliminate the safety hazards existing in the semi-high platform, a dedicated person is usually sent to conduct on-site patrol, or a dedicated person is sent to check whether there are any life bodies such as people or pets that pose safety hazards by watching monitoring videos, and reminds passengers not to approach the semi-high platform and not to climb over the platform in case of finding safety hazards. That is, the current platform monitoring method relies heavily on manpower, cannot effectively save labor costs, and due to the instability of manual monitoring, it is also difficult to guarantee the recognition rate of behaviors with safety hazards.

[0063] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0064] Before the specific embodiments of the present disclosure are described in detail, the application scenarios of the present disclosure are first described as follows. The present disclosure can be applied to a life monitoring process, for example, can be applied to a scenario of monitoring whether a passenger climbs over a platform door or is in a dangerous area in a semi-closed platform in rail transit, or a scenario of monitoring whether a tourist enters a prohibited area in a scenic area. Here, the scenario of monitoring whether a passenger climbs over a platform door or is in a dangerous area is taken as an example for description. A semi-closed waiting platform usually has a semi-high platform of about 1.5 meters arranged between a train running area and a waiting platform to separate the train running area and the waiting platform. Since the part of the semi-high platform that is higher than 1.5 meters does not have isolation facilities, the behavior of climbing over the platform often occurs, which poses a serious safety hazard. In the current semi-high platform operation mode, in order to eliminate the safety hazard of the semi-high platform, a dedicated person is usually arranged to conduct on-site patrol, or a dedicated person is arranged to check whether a life body such as a person or a pet exists in a safety hazard by watching monitoring videos, and reminds passengers not to approach the semi-high platform and not to climb over the platform when a safety hazard is found. That is, the current platform monitoring method has a strong dependence on manpower, cannot effectively save labor costs, and due to the instability of manual monitoring, it is easy to miss individual dangerous life bodies with safety hazards, so there are problems of low monitoring recognition rate and poor reliability.

[0065] In order to solve the above technical problems, the present disclosure provides a platform monitoring system and method. The method acquires a life detection signal in a preset platform monitoring space. When the life detection signal is acquired, it is determined whether a dangerous life body exists in the platform monitoring space according to the life detection signal. When it is determined that the dangerous life body exists in the platform monitoring space, a target area where the dangerous life body is located is determined. According to the target area, a target danger level corresponding to the dangerous life body is determined. According to the target danger level, an alarm strategy matched with the target danger level is executed. The degree of automation of platform monitoring can be improved, the recognition rate of dangerous life bodies can be improved, and different alarm strategies can be executed for dangerous life bodies with different danger levels, so that the probability of safety accidents can be effectively reduced.

[0066] Figure 1 is a schematic diagram of a platform monitoring system according to an example embodiment of the present disclosure; see Figure 1 The system comprises a controller 101, and a monitoring assembly 102 and an alarm device 103 connected to the controller 101.

[0067] The monitoring assembly 102 is configured to acquire a life detection signal in a preset platform monitoring space.

[0068] The controller 101 is configured to determine whether there is a dangerous life body in the platform monitoring space according to the life detection signal when the monitoring assembly acquires the life detection signal, determine a target area where the dangerous life body is located according to the life detection signal, determine a target danger level corresponding to the dangerous life body according to the target area, and send a control instruction to the alarm device according to the target danger level, the control instruction being used to control the alarm device to execute an alarm strategy matched with the target danger level.

[0069] The alarm device 103 is configured to execute an alarm strategy corresponding to the target danger level according to the control instruction.

[0070] The monitoring assembly 102 can comprise a plurality of infrared sensors 1021, and different infrared sensors 1021 are configured to acquire life detection signals in different areas of the platform monitoring space.

[0071] It should be noted that the plurality of infrared sensors 1021 can be distributed on the platform ground according to a preset distribution rule. The distribution rule can be that the platform ground corresponding to the platform monitoring space is divided into a grid, and the plurality of infrared sensors 1021 are distributed at the intersection points of the grid (as shown in Figure 2a , and Figure 2a is a distribution diagram of an infrared sensor according to another example embodiment of the present disclosure); or, the plurality of infrared sensors are distributed on target straight lines parallel to the plane where the platform door is located. The target straight lines can comprise a plurality of target straight lines, and one infrared sensor 1021 is distributed on each target straight line at a preset distribution distance. The preset distribution distances of adjacent two infrared sensors 1021 on different target straight lines can be different, and the interval distances between every two adjacent target straight lines in the plurality of target straight lines can be different (as shown in Figure 2b , and Figure 2b is a distribution diagram of an infrared sensor according to another example embodiment of the present disclosure); or, the plurality of infrared sensors are distributed in a preset warning mark pattern (for example, the shape of an exclamation mark). The infrared sensors distributed in the preset warning mark pattern can not only acquire life detection signals in their own monitoring areas, but also improve the aesthetics of the platform.

[0072] In addition, the angle a at which each infrared sensor 1021 radiates infrared light can range from 30° to 45°, and the monitoring area corresponding to each infrared sensor 1021 is the area range within which the infrared sensor can radiate infrared light, as shown in FIG. 2. Figure 2c Figure 2c As shown in FIG. 2, which is a schematic diagram of the working principle of the monitoring assembly according to an example embodiment of the present disclosure, when the interval between two adjacent infrared sensors 1021 is close, the monitoring areas of the two adjacent infrared sensors 1021 can overlap, and when the interval between two adjacent infrared sensors 1021 is far, the monitoring areas of the two adjacent infrared sensors 1021 do not overlap. The interval distance between adjacent infrared sensors can be adjusted according to monitoring requirements, and the present disclosure does not limit this.

[0073] The above technical solution can determine whether a dangerous living body exists in the platform monitoring space according to the life detection signal, and in the case where it is determined that the dangerous living body exists in the platform monitoring space, determine the target danger level corresponding to the dangerous living body, execute an alarm strategy that matches the target danger level according to the target danger level, which can improve the degree of automation of platform monitoring, improve the recognition rate of dangerous living bodies, and can execute different alarm strategies for dangerous living bodies of different danger levels, thereby more effectively reducing the probability of occurrence of safety accidents.

[0074] Optionally, the controller 101 is further configured to:

[0075] acquire the length of time during which the life detection signal is continuously detected; and determine that the dangerous living body exists when the length of time is greater than or equal to a preset time threshold, and determine that the dangerous living body does not exist when the length of time is less than the preset time threshold.

[0076] ​In one embodiment, the time length can be the time length that the current living body stays in the platform monitoring space. When the time length that the current living body stays in the platform monitoring space is greater than or equal to a preset time threshold, the current living body is determined as a dangerous living body, i.e., the dangerous living body exists in the platform monitoring space. When the time length that the current living body stays in the platform monitoring space is less than the preset time threshold, the current living body is determined as a non-dangerous living body, i.e., the dangerous living body does not exist in the platform monitoring space. For example, the first infrared sensor obtains the time length of the life detection signal corresponding to passenger A as 10 seconds, and then the second infrared sensor obtains the time length of the life detection signal corresponding to the passenger A as 5 seconds, i.e., the passenger A stays in the first monitoring area in the platform monitoring space for 10 seconds and then moves to the second monitoring area in the platform monitoring space and stays in the second monitoring area for 5 seconds. Thus, the time length that the passenger A stays in the platform monitoring space is 15 seconds. In this way, the time length that each passenger staying in the platform monitoring space is calculated separately, so as to determine whether each passenger staying in the platform monitoring space is a dangerous living body, thereby effectively improving the identification rate of the dangerous living body.

[0077] In another embodiment, the time length can be the time that a living body exists in the platform monitoring space. For example, the passenger A stays in the platform monitoring space for 15 seconds, and during the 15 seconds, the passenger B enters the platform monitoring space and stays in the platform monitoring space for 10 seconds after the passenger A leaves the platform monitoring space. Thus, the time length is 25 seconds. In this way, whether a dangerous living body exists is determined according to the total time that multiple living bodies stay in the platform monitoring space, so as to avoid the phenomenon that too many passengers enter the platform monitoring space in a short time without a dangerous warning, thereby effectively improving the reliability of the platform monitoring system.

[0078] Optionally, the monitoring assembly 102 includes a plurality of infrared sensors 1021, and different infrared sensors 1021 are configured to obtain life detection signals of different areas in the platform monitoring space and send the life detection signals to the controller 101.

[0079] 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 a 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 target danger level of the dangerous living body according to the target distance.

[0080] The implementation of determining the target distance between the target area and the plane where the platform door is located can include the following two implementations.

[0081] In one implementation, a target position in the target area closest to the plane where the platform door is located is obtained, and a distance between the target position and the plane where the platform door is located is determined as the target distance between the target area and the plane where the platform door is located.

[0082] In another implementation, since the target detection area corresponding to each infrared sensor is fixed after the infrared sensor is installed, that is, the target distance between the target area and the plane where the platform door is located is a fixed value, the target distance between each target area and the plane where the platform door is located can be pre-stored in the system. After the target area is determined, the target distance corresponding to the target area can be directly called to reduce the time for obtaining the target distance, improve the speed of determining the target danger level corresponding to the dangerous living body, and thus improve the detection efficiency of the platform monitoring system and reduce the probability of safety accidents.

[0083] For example, after the passenger C enters the platform monitoring space, the infrared sensor numbered (x, y) obtains 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 receiving the life detection signal corresponding to the passenger C, the controller 101 determines the number (x, y) of the infrared sensor from which the life detection signal corresponding to the passenger C is collected, determines the target detection area (area A) corresponding to the infrared sensor numbered (x, y) according to the number (x, y), and indicates that the passenger C is currently in area A. The target distance between area A and the plane where the platform door is located can be obtained. In the platform monitoring system, the correspondence between the number (x, y) and the target detection area (area A) is pre-stored. When the number is (x, y), the target detection area (area A) corresponding to the number (x, y) can be obtained.

[0084] It should be noted that when multiple infrared sensors detect life detection signals, the number of the infrared sensor corresponding to each life detection signal is obtained, the detection area corresponding to each numbered infrared sensor is obtained, the target detection area closest to the plane where the platform door is located is determined from the multiple 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, the target detection area corresponding to each numbered infrared sensor is pre-stored.

[0085] Optionally, the controller 101 is further configured to:

[0086] In a case where the target distance is less than or equal to the first distance threshold, the target danger level of the dangerous living body at present is determined as a high danger level.

[0087] In a case where the target distance is greater than the first distance threshold and less than a second distance threshold, it is determined that the target danger level of the dangerous living body at present is a middle danger level;

[0088] In a case where the target distance is greater than or equal to the second distance threshold, it is determined that the target danger level of the dangerous living body at present is a primary danger level.

[0089] Wherein, the first distance threshold is less than the second distance threshold, the smaller the target distance is, the smaller the distance between the dangerous living body and the platform door plane is, and the higher the danger level corresponding to the dangerous living body at present is.

[0090] It should be noted that, when the target danger level is determined to be the high 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 middle danger level, the alarm device can be controlled to play audio information in a broadcast manner, and the audio information can be a pre-recorded warning voice; when the danger level is determined to be the primary danger level, the alarm device can be controlled to perform light alarm, and preset text prompt information and / or image prompt information can be output at the same time of light alarm.

[0091] Optionally, the system further comprises a temperature sensor 104, and the monitoring assembly further comprises an electromagnetic wave detector 1022,

[0092] The temperature sensor 104 is configured to detect a current environment temperature;

[0093] The electromagnetic wave detector 1022 is configured to acquire the life detection signal and a target area where a living body corresponding to the life detection signal is located by means of electromagnetic wave;

[0094] The controller 101 is further configured to acquire the life detection signal and the target area where the corresponding living body is located in the platform monitoring space by means of the electromagnetic wave detector 1022 when the environment temperature is greater than or equal to a preset temperature threshold, and acquire the life detection signal in the platform monitoring space by means of the infrared sensor 1021 when the environment temperature is less than the preset temperature threshold.

[0095] It should be noted that the infrared sensor 1021 acquires the life detection signal, which is affected by the surface temperature of the object, and the temperature of the human body is usually between 34 DEG C and 40 DEG C, and in a high temperature environment, the ambient temperature is also easy to belong to 34 DEG C to 40 DEG C, in order to improve the reliability of the corresponding monitoring result of the platform monitoring system, when the ambient temperature is greater than or equal to the preset temperature threshold (for example, it can be 34 DEG C), the life detection signal in the platform monitoring space and the target area where the life corresponding to the life detection signal is located can be acquired by the electromagnetic wave detector (such as radar). In this way, 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.

[0096] The above technical scheme can determine whether there is a dangerous life in the platform monitoring space according to the life detection signal, and in the case that it is determined that the dangerous life exists in the platform monitoring space, the target danger level corresponding to the dangerous life is determined, the alarm strategy matched with the target danger level is executed according to the target danger level, the automation degree of platform monitoring can be improved, the recognition rate of dangerous life can be improved, and different alarm strategies can be executed for dangerous life of different danger levels, so that the probability of safety accident can be effectively reduced.

[0097] Figure 3 It is a flow chart of a platform monitoring method according to an example embodiment of the present disclosure; see Figure 3 The method can comprise the following steps:

[0098] Step 301, acquiring a preset life detection signal in the platform monitoring space.

[0099] The platform monitoring space can be a preset space area near the platform door in the platform, and the 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 can include a plurality of infrared sensors or at least one electromagnetic wave detector.

[0100] It should be noted that the platform monitoring system can also include a temperature sensor, which is used to detect the current ambient temperature; the electromagnetic wave detector is used to acquire the life detection signal and the target area where the life corresponding to the life detection signal is located by electromagnetic wave. When the ambient temperature is greater than or equal to the preset temperature threshold, the life detection signal in the platform monitoring space and the target area where the life corresponding to the life detection signal is located are acquired by the electromagnetic wave detector; when the ambient temperature is less than the preset temperature threshold, the life detection signal in the platform monitoring space is acquired by the infrared sensor.

[0101] Step 302, in the case of obtaining the life detection signal, determining whether there is a dangerous life body in the platform monitoring space according to the life detection signal.

[0102] In this step, the length of time during which the life detection signal is continuously detected can be obtained; when the length of time is greater than or equal to a preset time threshold, it is determined that the dangerous life body exists; when the length of time is less than the preset time threshold, it is determined that the dangerous life body does not exist.

[0103] It should be noted that in one embodiment, the length of time can be the time during which the life detection signal corresponding to the current life body is continuously detected in the platform monitoring space; when the length of time during which the current life body appears in the platform monitoring space is greater than or equal to a preset time threshold, it is determined that the current life body is a dangerous life body, i.e., the dangerous life body exists in the platform prediction space; when the length of time during which the current life body appears in the platform monitoring space is less than the preset time threshold, it is determined that the current life body is a non-dangerous life body, i.e., the dangerous life body does not exist in the platform monitoring space; in another embodiment, the length of time can be the time during which a life body always exists in the platform monitoring space.

[0104] Step 303, in the case of determining that the dangerous life body exists in the platform monitoring space, determining a target area where the dangerous life body is located.

[0105] The platform monitoring system includes a plurality of infrared sensors, and different infrared sensors are used to obtain life detection signals in different areas of the platform monitoring space. The plurality of infrared sensors are distributed according to any one of the following distribution rules:

[0106] Distribution rule one, the plurality of infrared sensors are distributed at intersection points of a preset grid, and the preset grid is arranged on a platform ground corresponding to the platform monitoring space;

[0107] Distribution rule two, the plurality of infrared sensors are distributed on a plurality of target straight lines parallel to the plane where the platform door is located;

[0108] Distribution rule three, the plurality of infrared sensors are distributed in a preset warning mark pattern.

[0109] In one possible embodiment of the step, in the case of receiving the life detection signal, a target identification of a target infrared sensor sending the life detection signal is obtained; a target detection area corresponding to the target infrared sensor is determined according to the target identification; and the target detection area is determined as the target area where the dangerous life body is located.

[0110] Step 304, determining a target danger level corresponding to the dangerous life body according to the target area.

[0111] In one possible implementation, the target distance between the target area and the plane where the platform door is located is determined, and a current target danger level of the dangerous life body is determined according to the target distance.

[0112] In another possible implementation, the target distance between each target area and the plane where the platform door is located is pre-stored in the system, and after the target area is determined, the target distance corresponding to the target area can be directly called to determine the current target danger level of the dangerous life body according to the target distance.

[0113] It should be noted that the determination of the current target danger level of the dangerous life body according to the target distance can include: in the case where the target distance is less than or equal to a first distance threshold, determining that the current target danger level of the dangerous life body is a high danger level; in the case where the target distance is greater than the first distance threshold and less than a second distance threshold, determining that the current target danger level of the dangerous life body is a middle danger level; and in the case where the target distance is greater than or equal to the second distance threshold, determining that the current target danger level of the dangerous life body is a primary danger level.

[0114] In step 305, an alarm strategy matched with the target danger level is executed according to the target danger level.

[0115] It should be noted that when the target danger level is determined to be the high danger level, the photoelectric generator in the alarm device is controlled to generate a photoelectric warning signal, and the dangerous life body is prompted to leave the platform monitoring space through the photoelectric warning signal. When the target danger level is determined to be the middle danger level, the alarm device can be controlled to broadcast audio information, which can be a pre-recorded warning voice. When the target danger level is determined to be the primary danger level, the alarm device can be controlled to perform light alarm, and preset text prompt information and / or image prompt information can be output at the same time.

[0116] The above technical solution can determine whether there is a dangerous life body in the platform monitoring space according to the life detection signal, determine the target danger level corresponding to the dangerous life body when it is determined that there is a dangerous life body in the platform monitoring space, execute an alarm strategy matched with the target danger level according to the target danger level, improve the automation degree of platform monitoring, improve the recognition rate of dangerous life bodies, and execute different alarm strategies for dangerous life bodies with different danger levels, thereby effectively reducing the probability of safety accidents.
