Description

[Technical field]

[0001] The present invention relates to a home detection device and a home detection system. [Background technology]

[0002] A vehicle type discrimination device has been disclosed that discriminates the vehicle type based on feature points on the roof of a train car detected by multiple feature point sensors installed on the roof of a platform (Patent Document 1).Also disclosed is a platform door opening / closing control device that turns on only the optical sensor among multiple optical sensors that is estimated to be located closest to the crew according to the train's stopping position detected by a stopping position detection unit, and controls the opening and closing of the platform door device based on the detection results of the optical sensors (Patent Document 2).

[0003] A plurality of sensors are installed in the devices of Patent Documents 1 and 2. Since each sensor in the devices of Patent Documents 1 and 2 is a dedicated sensor for detecting one detection target, a processing device and an installation location, etc. are required for each sensor, which increases costs and poses problems such as securing installation space.

[0004] [Patent Document 1] Patent Publication No. 2022-26191 [Patent Document 2] Patent Publication No. 2021-66410 Summary of the Invention

[0005] The present invention has been made in consideration of the above-mentioned points, and has an object to provide a platform detection device and a platform detection system that can accommodate multiple detection purposes and reduce installation space and costs.

[0006] In order to achieve the above-mentioned objective, the home detection device of the present invention comprises a detection unit that detects detection targets having different detection purposes in individual detection areas within a monitoring range, and a determination unit that aggregates multiple processing procedures corresponding to the detection purposes and determines the condition within the individual detection area using a processing procedure among the multiple processing procedures that is appropriate for the detection target.

[0007] According to the above platform detection device, the determination unit consolidates multiple processing procedures corresponding to the detection purposes, so that one platform detection device can handle multiple detection purposes. This allows one platform detection device to be used for detection of different detection purposes. Therefore, it is no longer necessary to provide dedicated detection devices for each detection purpose, which reduces costs and saves installation space.

[0011] [Embodiment] Hereinafter, a home detection device and a home detection system according to an embodiment will be described with reference to the drawings.

[0012] Fig. 1 is a conceptual plan view illustrating a station platform PF and a platform detection system 100. Fig. 1 shows a state in which a train TR enters a track RL corresponding to the platform PF in the direction of arrow A and stops at a fixed position.

[0013] The platform detection system 100 is a platform monitoring system that monitors the status of passengers and the status of trains TR. The platform detection system 100 monitors the entire monitoring area AR using a plurality of platform detection devices 20, which will be described later. Specifically, the platform detection system 100 detects the position of passengers using the platform detection devices 20, and can alert passengers who are close to the platform end PF1, i.e., the platform terminal position on the track RL side. The platform detection system 100 also supports safety at the platform PF by detecting the position and fixed position of the train TR and detecting the opening and closing of the doors DR of the train TR.

[0014] FIG. 2 is a block diagram illustrating the configuration of the home detection system 100. As shown in FIG.

[0015] The home detection system 100 includes a general control panel 10, a plurality of home detection devices 20, a plurality of relay devices 30, and a management device 90. In the illustrated example, n home detection devices 20 (home detection devices 20-1 to 20-n) are installed in one home PF. For example, three home detection devices 20 are connected to each relay device 30. The number of home detection devices 20 connected to the relay device 30 can be changed as appropriate.

[0016] The general control panel 10 controls and monitors the platform detection devices 20. Based on information from various devices, the general control panel 10 switches and notifies the operation status and operation mode of the platform detection system 100. Specifically, the general control panel 10 controls audio output, display output, and status notification based on input from the relay device 30, an operation panel (not shown), etc. One general control panel 10 is installed for one platform PF. Note that one general control panel 10 may be installed for multiple platform PFs.

[0017] The general control panel 10 includes a control device 11, a distribution board 12, a communication device 13, and a hub 14. The control device 11 controls the operation of the distribution board 12, the communication device 13, and the like. The control device 11 also manages the operation of the home detection device 20, the relay device 30, and the like. The distribution board 12 supplies power to the home detection device 20, and the like. The power supply system to the home detection device 20, and the like is branched for each relay device 30. The communication device 13 enables communication with the management device 90 via a communication network NT. The communication network NT is, for example, a local area network (LAN), but is not limited to this and may be a wide area network (WAN), the Internet, or a combination of these. The communication network NT may also include a public switched telephone network (PSTN), an integrated services digital network (ISDN), and the like. The hub 14 is connected to the relay device 30 by a communication line CC. From the relay device 30 to the hub 14, for example, a string of Ethernet communication networks is formed. Between the general control panel 10 and the relay device 30, a serial communication network for controlling the home detection device 20 is formed in a loop shape.

[0018] The platform detection device 20 monitors the state of the platform PF and the vehicle state of the train TR, and notifies the platform PF, the management device 90, etc. The platform detection device 20 detects the presence or absence of passengers on the platform PF and the vehicle state of the train TR, and outputs the information to the general control panel 10, etc. Each platform detection device 20 is set with a unique identification number that identifies that platform detection device 20. By linking the sensor information, determination results, etc. of each platform detection device 20 to the unique identification number, the platform detection device 20 can transmit and receive information to other platform detection devices 20, the general control panel 10, the management device 90, etc.

[0019] 3 and 4 are conceptual diagrams for explaining the platform detection device 20 installed at the platform PF. FIG. 3 is a view of the track RL (see FIG. 1) side from the platform PF side, and FIG. 4 is a view of the platform PF from the side. The platform detection device 20 is suspended from the ceiling at the platform end PF1. The platform end PF1 is within an inner range of, for example, about 450 mm from the platform end face PF3 at the platform PF. In the example of FIG. 3 and FIG. 4, the platform detection device 20 is attached near the platform roof RF and monitors passengers and the like present on the platform PF from above. As shown in FIG. 1 etc., a plurality of platform detection devices 20 are arranged along the running direction of the train TR. The number of platform detection devices 20 to be installed corresponds to the length of the platform PF.

[0020] As shown in FIG. 1, the platform detection device 20 has a monitoring range AR including the platform edge PF1 and the vehicle side surface VX of the train TR. As shown in FIG. 1 to FIG. 3, each platform detection device 20 has an individual detection area IA, which is its own detection range. In the case of a ceiling-mounted platform detection device 20, the individual detection area IA has a shape obtained by cutting out a part of a cone and spreads out like a fan from above. The combined area of ​​the individual detection areas IA of all the platform detection devices 20 covers the monitoring range AR. In adjacent individual detection areas IA, an overlapping area IB occurs near the platform floor surface PF2 where the detection areas overlap, but the sensor data, etc. of the overlapping area IB are processed by extracting the difference or common part. In the illustrated example, when multiple individual detection areas IA are combined, the entire monitoring range AR becomes the detection range on the platform floor surface PF2, but there may be some gap between adjacent individual detection areas IA.

[0021] As shown in FIG. 2, the platform detection device 20 has a control unit 21, a detection unit 22, an indicator light 23, and a speaker 24. The platform detection device 20 aggregates a plurality of processing procedures (logic) corresponding to the detection purpose. As a result, in the platform detection system 100, the specifications of each platform detection device 20 are unified. In other words, the platform detection devices 20 are equipped with the same software, and the operation of each device can be unified. The platform detection device 20 can determine the presence or absence of a passenger by a passenger detection function. In addition, the platform detection device 20 can determine the vehicle state by a vehicle position detection function, a fixed position stop detection function, and a door opening / closing detection function. In other words, in this embodiment, the detection purposes of the platform detection device 20 are passenger detection, vehicle position detection, fixed position stop detection, and door opening / closing detection. The detection targets of passenger detection are people (passengers) and objects. The detection targets of vehicle position detection, fixed position stop detection, and door opening / closing detection are the vehicles 2 of the train TR.

[0022] The control unit 21 controls the operation of the detection unit 22, the indicator lamp 23, the speaker 24, etc. The control unit 21 includes a processing unit 21a and a determination unit 21b. The processing unit 21a performs an analysis process on the sensor data (specifically, image data or point cloud data) acquired by the detection unit 22, and creates sensor information. The determination unit 21b performs various determinations on the sensor information (analysis information) analyzed by the processing unit 21a. The determination unit 21b aggregates multiple processing procedures corresponding to the detection purpose, and determines the state within the individual detection area IA using a processing procedure corresponding to the detection target among the multiple processing procedures. The determination unit 21b obtains a difference based on a predetermined criterion for the detection result (sensor data) of the detection unit 22 by the processing procedure, and determines the state of the detection target from the difference. The state within the individual detection area IA corresponds to the presence or absence of a person (passenger) and an object on the platform PF, the position of the train TR, the fixed stop state of the train TR, and the open / close state of the doors of the train TR.

[0023] The detection unit 22 acquires sensor data (image data or point cloud data) regarding the platform PF and the train TR stopped at the platform PF. The image data includes distance measurement data. The detection unit 22 can measure whether or not a person (passenger) or the like is present in a predetermined area within the individual detection area IA, whether or not a train TR or a vehicle 2 is on the track RL, and whether or not the door DR of the train TR is open. The detection unit 22 can also determine whether the train TR is stopped at a fixed position. The detection unit 22 is, for example, a three-dimensional sensor or a two-dimensional sensor. The three-dimensional sensor is, for example, an optical sensor such as LiDAR (light detection and ranging). The two-dimensional sensor is, for example, a camera. It is preferable that the camera is one that performs distance measurement using a TOF (Time Of Flight) method or the like.

[0024] The detection unit 22 detects detection targets with different detection purposes in an individual detection area IA within the monitoring range AR. The individual detection area IA includes a range in which the platform PF and the train TR can be detected simultaneously. The detection unit 22 is installed so as to be able to detect the vehicle state of the train TR. Specifically, the detection unit 22 is installed on the upper side (+Z side) of the platform PF with the detection surface facing downward (-Z side). As the individual detection area IA includes the area above the track RL, it is possible to measure the distance to a running or stopped train TR. The detection unit 22 sets a vehicle detection area for detecting the vehicle side surface VX and the coupling portion RR in the sensor angle of view so as to be able to determine the vehicle state.

[0025] The indicator lamp 23 indicates an abnormal state and the like, and notifies station staff of the state. The indicator lamp 23 is attached in a position where it can be seen by station staff.

[0026] When the speaker 24 detects an abnormal state or the like, it alerts passengers by sounding a voice or sounding a buzzer, etc. The speaker 24 is attached in a position where it can alert passengers in the vicinity of the platform end PF1.

[0027] An example of the detection area of ​​the home detection device 20 will now be described.

[0028] As shown in FIG. 4, the detection unit 22 divides the individual detection area IA into a danger detection area IA1, a caution detection area IA2, a vehicle detection area IA3, and a fall detection area IA4 in order to call attention to passengers and detect vehicles according to their standing positions. The detection areas IA1 to IA4 are reference areas for judgment by the judgment unit 21b. In other words, the judgment unit 21b performs various judgments on detection targets present in the detection areas IA1 to IA4. The detection areas IA1 to IA4 are sequentially divided and set from the vicinity of the platform roof RF through the platform floor surface PF2 toward the track RL. In the case of a suspended type, the detection unit 22 is arranged at a position that covers a range of about 2 m above the platform floor surface PF2, for example, and at a position where the fall detection area IA4 on the track RL side can be set.

[0029] The danger detection area IA1 is, for example, a range on the platform PF side of the monitoring range AR that is 50 mm or more and less than 250 mm from the platform end face PF3. The caution detection area IA2 is, for example, a range on the platform PF side of the monitoring range AR that is 250 mm or more and 450 mm or less from the platform end face PF3. The vehicle detection area IA3 is a range on the track RL side of the platform end face PF3 of the monitoring range AR and above the platform floor surface PF2. The fall detection area IA4 is a range on the track RL side of the platform end face PF3 of the monitoring range AR and below the platform floor surface PF2.

[0030] An example of the detection function of the home detection device 20 will now be described.

[0031] The platform detection device 20 has a passenger detection function, a vehicle position detection function, a fixed position stop detection function, and a door opening / closing detection function.

[0032] In the passenger detection function, the control unit 21 of the platform detection device 20 functions as a determination unit 21b to detect people (passengers) or objects at the platform end PF1. The determination unit 21b determines whether or not there are people or objects in the danger detection area IA1 and the caution detection area IA2. If a passenger or the like is present in the danger detection area IA1 and the caution detection area IA2, the control unit 21 operates the speaker 24 to sound an alarm to alert the passengers or the like. Note that when the train TR is stopped, the control unit 21 does not cause the speaker 24 to sound an alarm.

[0033] The platform detection device 20 can also detect falls in addition to passenger detection. The control unit 21 functions as the determination unit 21b, which detects passengers who have fallen off the platform PF. The determination unit 21b determines whether or not there is a person or object in the fall detection area IA4. To prevent erroneous detection of objects other than passengers, the determination unit 21b performs detection avoidance with a detection time period of, for example, 1 second and only detects objects of 200 mm or more.

[0034] The platform detection device 20 maintains the fall detection monitoring level at a predetermined value in all states of the train TR, whether it is not present on the tracks, entering the tracks, before departing, or leaving the tracks. The platform detection device 20 sets the monitoring levels for caution detection and danger detection higher when the train TR is entering the tracks, before departing, or leaving the tracks than when it is not present on the tracks, stopped at its regular position, or the doors are open. Note that when the train TR is not present on the tracks, stopped at its regular position, or the doors are open, the monitoring levels for caution detection and danger detection may be zero.

[0035] In the vehicle position detection function, the control unit 21, as the determination unit 21b, determines the position where the vehicle 2 of the train TR is present based on the detection information within the vehicle detection area IA3. The determination unit 21b determines whether or not the leading vehicle of the train TR is present in the vehicle detection area IA3, and specifies the current position of the train TR. The determination unit 21b also determines whether or not the vehicle side surface VX of the train TR is present in the vehicle detection area IA3. The determination result of the presence or absence of the vehicle side surface VX is shared by transmitting and receiving it to other platform detection devices 20, and the number of vehicles 2 that have entered the platform PF can be grasped. Note that the vehicle position detection function operates when the speed of the vehicle 2 is equal to or lower than the vehicle position detection speed, taking into consideration the train TR passing through the platform PF. The vehicle position detection speed is set to a maximum value of, for example, 30 km / h. The speed of the train TR is calculated, for example, by taking the difference between before and after a frame of an acquired sensor image.

[0036] In the fixed position stop detection function, the control unit 21, as the determination unit 21b, determines whether the train TR is stopped at a fixed position based on the detection information in the vehicle detection area IA3. The platform detection device 20 that performs the fixed position detection is set in advance by the general control panel 10, an operation panel (not shown), etc. All the platform detection devices 20 have the fixed position stop detection function, but the platform detection device 20 set with the fixed position stop detection function performs the fixed position stop determination. The criterion for the fixed position stop determination is the coupling part RR between the vehicles 2. In this case, the platform detection device 20 that detects the coupling part RR is set with the fixed position detection function. The determination unit 21b of the platform detection device 20 set with the fixed position detection function extracts the coupling part RR of the vehicle 2 from the sensor information, and determines that the train TR is stopped at a fixed position when the moving speed of the coupling part RR is equal to or less than the stop determination speed and is in a predetermined stop range. The criterion for the fixed position stop determination can be changed as appropriate, and for example, the position of the door DR may be used as the criterion for the fixed position determination. The fixed position stop determination can be performed by one platform detection device 20, but may be performed by a plurality of platform detection devices 20 to improve the accuracy of the determination.

[0037] In the door open / close detection function, the control unit 21, as the determination unit 21b, determines the open / closed state of the door DR of the train TR based on the detection information in the vehicle detection area IA3 and the above-mentioned determination result of the fixed position stop. When the train TR stops at the fixed position, the determination unit 21b determines the open / closed state of the door DR from the number of distance measurement points in the vehicle detection area IA3 near the vehicle side VX. The determination unit 21b extracts distance measurement points so that distance measurement points that detect passengers inside the vehicle from the window of the vehicle 2 are excluded from the determination. The determination unit 21b monitors the number of distance measurement points near the vehicle side VX and the number of distance measurement points inside the vehicle 2, and determines the open state when the number of distance measurement points inside the vehicle 2 is increasing, and determines the closed state when the number of distance measurement points inside the vehicle 2 is decreasing. The door open / closed state determination can be performed by one platform detection device 20, but may be performed by multiple platform detection devices 20 to improve the accuracy of the determination.

[0038] The platform detection device 20 also has a function of notifying the status of the detection unit 22. In the status notification function, the control unit 21 notifies the general control panel 10, etc. of the determination results of passenger detection, vehicle position detection, fixed position stop detection, and door opening / closing detection, and the status of the detection unit 22 (specifically, dirt, abnormality, etc.) at regular intervals.

[0039] The relay device 30 shown in FIG. 2 etc. supplies power to the multiple home detection devices 20 and relays communication between the home detection devices 20 and the general control panel 10. The relay device 30 transmits notifications from the general control panel 10 to the control units 21 of each home detection device 20. The relay device 30, for example, aggregates Ethernet and CAN communications with each home detection device 20. That is, the relay device 30 aggregates the Ethernet output and CAN communication output of each home detection device 20 and relays them to the general control panel 10. Each relay device 30 can be connected to multiple home detection devices 20. The home detection devices 20 notify the relay device 30 of the detection status by CAN communication, and the relay device 30 notifies the general control panel 10 by serial communication. The home detection device 20 can set the detection area and judgment parameters to be used for each detection function, etc., by Ethernet. Furthermore, the platform detection device 20 can output sensor information (for example, range image data and the like) acquired by the platform detection device 20 to a monitoring terminal (not shown) or the like installed in the station via Ethernet.

[0040] The management device 90 shown in FIG. 2 etc. integrates and manages the determination results of the multiple platform detection devices 20. The management device 90 is installed, for example, inside or outside a station, and manages or monitors the status of the platform PF. If the management device 90 is installed outside a station, it can manage or monitor the status of the platform PF at multiple stations. In this case, the management device 90 can integrate and manage information from the platform detection devices 20 at each station.

[0041] The management device 90 has a control device 91, a storage device 92, a user interface 93, and a communication device 94. The management device 90 communicates with the multiple home detection devices 20 via the communication network NT using the communication device 94. The storage device 92 stores a program for operating the management device 90. The storage device 92 also records determination results and sensor information from the multiple home detection devices 20. Information from the multiple home detection devices 20 is managed in an integrated manner and is used for monitoring the safety of the home PF and understanding the overall situation of the home PF, etc.

[0042] Hereinafter, with reference to FIG. 5, an example of processing operation of the determination unit 21b of the platform detection device 20 in the platform detection system 100 will be described. Predetermined conditions are set in the platform detection device 20 in advance. Specifically, the detection areas and determination parameters to be used for each detection function, the fixed position stop detection function, etc. are set in the platform detection device 20 via the relay device 30 by the general control panel 10 or an operation panel (not shown). The control unit 21 of the platform detection device 20 operates the detection unit 22 to acquire sensor data from the individual detection area IA. The control unit 21, as the processing unit 21a, performs various processes required for passenger detection, vehicle position detection, fixed position stop detection, and door opening / closing detection on the acquired sensor data, thereby acquiring corresponding sensor information.

[0043] The control unit 21 of the home detection device 20 inputs the sensor information to the determination unit 21b (step S11). The sensor data is acquired at a predetermined timing. In the following steps, the control unit 21 inputs the updated sensor information to the determination unit 21b as needed.

[0044] When the control unit 21 detects a passenger as a detection target by the passenger detection function (Y in step S12), the control unit 21 as the determination unit 21b determines whether or not a passenger has been detected in a predetermined area (step S13). The predetermined area is the danger detection area IA1, the caution detection area IA2, or the vehicle detection area IA3 in the individual detection area IA. If a passenger is not detected (N in step S12) or if a passenger is detected but outside the predetermined area (N in step S13), the process returns to step S11.

[0045] When the control unit 21 detects a passenger in a predetermined area (Y in step S13) and the speaker 24 is in operation (Y in step S14), the control unit 21 operates the speaker 24 and issues a report corresponding to the area where the passenger was detected (step S15). The control unit 21 also transmits the determination information in step S12 to the general control panel 10, etc. Note that in step S14, if the speaker 24 is not in operation because the train TR is stopped at its regular position (N in step S14), the process returns to step S11.

[0046] After step S15, the control unit 21, as the determination unit 21b, ends the announcement from the speaker 24 (step S18) if the sensor information is updated (Y in step S16) and a passenger is not detected (N in step S17). After step S18, the process returns to the start. Note that, if the control unit 21, as the determination unit 21b, detects a passenger again (Y in step S17), it returns to step S13.

[0047] After step S11, the control unit 21, as the determination unit 21b, detects the vehicle 2 to be detected by the vehicle position detection function (Y in step S21) and, if the moving speed of the vehicle 2 is equal to or lower than the vehicle position detection speed (Y in step S22), transmits determination information to the effect that the vehicle 2 has been detected to the general control panel 10 or the like (step S23). At this time, the control unit 21 also transmits information on the position of the vehicle 2 obtained by the vehicle position detection function. Note that, if the vehicle 2 is not detected (N in step S21) or if the vehicle 2 is detected but the moving speed of the vehicle 2 is faster than the vehicle position detection speed (N in step S22), the process returns to step S11.

[0048] After step S23, if the moving speed of the vehicle 2 is equal to or lower than the stop determination speed (Y in step S24), the control unit 21, as the determination unit 21b, determines that the vehicle 2 has stopped, and transmits the determination information to the general control panel 10, etc. (step S25). Meanwhile, if the moving speed of the vehicle 2 is faster than the stop determination speed (N in step S24), the process returns to step S11.

[0049] After step S25, if the platform detection device 20 is set to operate the fixed position stopping function (Y in step S26), the control unit 21, as the judgment unit 21b, detects the coupling part RR of the train TR, which is the detection target, by the fixed position stopping function (step S27).

[0050] When the control unit 21, acting as the judgment unit 21b, judges that the coupling part RR is in the fixed position (Y in step S28), it judges that the train TR has stopped in the fixed position and transmits the judgment information to the general control panel 10, etc. (step S29).

[0051] After step S29, the control unit 21 stops the operation of the speaker 24 (step S30).

[0052] In step S26, if the home detection device 20 is not set to operate the fixed position stop function (N in step S26), the control unit 21 waits for determination information of fixed position stop from another home detection device 20, and if the control unit 21 receives the determination information (Y in step S31), it stops the operation of the speaker 24 (step S30).

[0053] After step S30, the control unit 21, as the determination unit 21b, detects the door DR of the vehicle 2, which is the detection target, by the door open / close detection function (Y in step S41), and when it detects that the door DR is in an open state (Y in step S42), it determines that the door is in an open state and transmits the determination information to the general control panel 10, etc. (step S43). Here, in the door open state, passengers board and disembark in the vehicle 2. After passengers have boarded and disembarked, the door DR of the vehicle 2 is closed.

[0054] When the control unit 21, functioning as the determination unit 21b, detects that the door DR of the vehicle 2 is closed (Y in step S44), it determines that the door is closed, and transmits the determination information to the general control panel 10 or the like (step S45).

[0055] After step S45, the control unit 21 restores the operation of the speaker 24 (step S46).

[0056] If the control unit 21 does not detect the door DR in step S41 (N in step S41), it waits for determination information on the door closed state from another home detection device 20, and if it receives the determination information (Y in step S47), it restores the operation of the speaker 24 (step S46).

[0057] After step S46, if there is an update of the sensor information (Y in step S51) and the moving speed of the vehicle 2 is equal to or lower than the vehicle position detection speed (Y in step S52), the control unit 21, as the determination unit 21b, transmits determination information to the effect that the vehicle 2 has been detected to the general control panel 10, etc. (step S53). At this time, the control unit 21 also transmits information on the position of the vehicle 2 obtained by the vehicle position detection function. Note that, if the moving speed of the vehicle 2 is faster than the vehicle position detection speed (N in step S52), the control unit 21 transmits a message to the general control panel 10, etc. that the train TR has departed, and proceeds to the next step S54.

[0058] Thereafter, when the control unit 21, acting as the determination unit 21b, no longer detects the vehicle 2 (N in step S54), it transmits to the general control panel 10 or the like that the home PF is not present on the line (step S55). After step S55, the process returns to the start. Note that, when the vehicle 2 is detected in step S54 (Y in step S54), the process returns to step S52.

[0059] According to the above-mentioned platform detection device 20, the determination unit 21b consolidates a plurality of processing procedures corresponding to the detection purposes, so that a single platform detection device 20 can handle a plurality of detection purposes. This allows a single platform detection device 20 to be used for detection of different detection purposes. Therefore, it is no longer necessary to provide dedicated detection devices for each detection purpose, which allows for cost reduction and saving of installation space.

[0060] The platform detection system 100 can unify the above-mentioned platform detection devices, and therefore can facilitate maintenance.
