(First embodiment)
Hereinafter, with reference to FIGS. 1 to 9, a first embodiment of a home door device and a home door system will be described. Platform door devices are installed on platforms such as railways, and platform door systems are installed at stations.

As shown in FIG. 1, a plurality of platform door devices 20 are installed along a platform of a station and partition the platform into a track side and a platform side. The platform door device 20 opens and closes the entry/exit passage by moving the door 27 provided in the platform door device 20 in and out. In addition, the platform door device 20 includes an obstacle sensor 26 that detects passengers located between the train and the door 27. As the obstacle sensor 26, for example, a photoelectric sensor or a 3D sensor is used. The obstacle sensor 26 outputs a detection result when it detects an obstacle. Further, the obstacle sensor 26 outputs a detection signal while detecting the passengers when the door 27 is open.

The home door device 20 includes a home door control device 21 that controls the home door device 20 and a motor 28 that drives the door 27. The home door control device 21 is also referred to as a Door Control Unit (DCU). In the following, when distinguishing each home door control device 21, it is described as “DCU#N (N=1, 2, 3,..., N)”. To do. The home door control device 21 acquires the detection result from the obstacle sensor 26. The home door control device 21 determines that the accumulated time during which the detection signal output from the obstacle sensor 26 is input when the door 27 is open is the boarding/alighting detection time required for the passengers to get on and off.

The home door control device 21 includes a drive unit 22 that controls the drive of the motor 28. The motor 28 is driven according to the drive command of the drive unit 22 to open/close the door 27.

The home door control device 21 includes a storage unit 23 that stores information necessary for the operation of the door 27. The storage unit 23 stores parameter data DP for controlling the opening/closing of the door 27, operation record data DE of the door 27, and the like. The storage unit 23 stores the drive command issued by the drive unit 22 as an operation record. The storage unit 23 also stores the detection results detected by the obstacle sensor 26 as the operation result data DE. The parameter data DP are parameters for the home door device 20 and each time period. The operation record data DE is an operation record in at least one of the same situation in the past, the same station, the same train type, and the like. The same situation includes not only the same time but also the same condition, season and weather, presence/absence of an event near the station, and the like. The drive unit 22 controls the opening/closing drive of the door 27 according to the parameter of the parameter data DP stored in the storage unit 23.

The home door control device 21 includes a generation unit 24 that generates a parameter for controlling opening/closing of the door 27. The generation unit 24 generates a parameter for controlling the opening/closing of the door 27 based on the operation result data DE stored in the storage unit 23. For example, the generation unit 24 identifies a time zone in which train operation is likely to be delayed by analyzing past operation records, and generates an appropriate parameter for each time zone. The generation unit 24 stores the generated parameter in the storage unit 23 as parameter data DP. The storage unit 23 may store the parameter data DP in advance when the platform door device 20 is installed, or may store the parameters while operating the platform door device 20.

The generation unit 24 rewrites the parameter data DP in the storage unit 23 when the parameter data DP stored in the storage unit 23 has a parameter that needs to be changed. That is, the parameter of the door 27 of the home door device 20 can be set according to the situation by the home door device 20 generating the parameter based on the operation record and automatically updating the parameter.

The home door control device 21 includes a control unit 25 that controls opening/closing of the door 27 based on the parameters generated by the generation unit 24. The control unit 25 extracts, for example, a parameter of a time zone to be controlled from the parameter data DP stored in the storage unit 23, and controls the opening/closing of the door 27.

It should be noted that a part of the home door control device 21 corresponds to a control parameter generation device of the home door device, and the storage unit 23 and the generation unit 24 of the home door control device 21 generate parameters for controlling the opening and closing of the door 27.

As shown in FIG. 2, the platform door system 10 includes a plurality of platform door devices 20 installed in the station 1 and an integrated control panel 11 that controls the platform door devices 20. Home door control devices 21 (DCU#1, DCU#2,..., DCU#N) of each home door device 20 are connected to the general control panel 11. Each home door control device 21 (DCU#1, DCU#2,..., DCU#N) periodically transmits the operation record of each home door device 20 to the general control panel 11.

The integrated control panel 11 includes a storage unit 12 that stores information about each home door device 20. The storage unit 12 stores parameter data DP for controlling the door 27 by each home door control device 21 (DCU#1, DCU#2,..., DCU#N) and each home door control device 21 (DCU#1, DCU#). 2,..., DCU#N) and stores the operation result data DE and the like. The parameter data DP may be parameters for each home door device 20 and each time period, or parameters for each platform unit and each time period.

The integrated control panel 11 includes a generation unit 13 that generates parameters for controlling the opening and closing of the door 27 by each home door control device 21 (DCU#1, DCU#2,..., DCU#N). The generation unit 13 determines each home door control device 21 (DCU#1, DCU#2) based on the operation result data DE acquired from each home door control device 21 (DCU#1, DCU#2,..., DCU#N). ,..., DCU#N) generates parameters for controlling opening/closing of the door 27. For example, the generation unit 13 analyzes the past operation record acquired from each of the home door control devices 21 (DCU#1, DCU#2,..., DCU#N) to easily delay the train operation. Specify the zone and generate appropriate parameters for each door and time zone. The generation unit 13 stores the generated parameter in the storage unit 12 as parameter data DP. Note that the storage unit 12 may store the parameter data DP in advance when the integrated control panel 11 is installed, or may store the parameters while operating.

The generation unit 13 rewrites the parameter data DP in the storage unit 12 when the parameter data DP stored in the storage unit 12 includes a parameter that needs to be changed. Then, the parameter data DP corresponding to each home door control device 21 (DCU#1, DCU#2,..., DCU#N) is set to each home door control device 21 (DCU#1, DCU#2,..., DCU#N). ) To. Each home door control device 21 (DCU#1, DCU#2,..., DCU#N) stores the parameter data DP acquired from the general control panel 11 in the storage unit 23. That is, the general control panel 11 generates parameters based on the operation record of each home door apparatus 20 and automatically updates the parameters, so that the parameters of the door 27 of the home door apparatus 20 can be set according to the situation.

A part of the integrated control panel 11 corresponds to a control parameter generation device of the home door device, and the storage unit 12 and the generation unit 13 of the integrated control panel 11 generate parameters for controlling the opening and closing of the door 27.

Next, two examples of parameter generation by the generation unit 24 or the generation unit 13 will be described with reference to FIGS.

(Example 1)
In Example 1 shown in FIGS. 3 and 4, the generation unit 24 or the generation unit 13 analyzes the statistical data of the entry/exit detection time and lengthens the fully open time of the door 27. That is, when the time required for all passengers to get on and off in the predetermined time zone of the predetermined door 27 is longer than the predetermined time, the generation unit 24 or the generation unit 13 performs the opening/closing operation of the door 27 in the time zone of the door 27. Reduce the time required. Therefore, the boarding/alighting time for which the door 27 is fully opened becomes long, and the time required for the boarding/alighting passengers to get on/off can be secured at the time of congestion.

FIG. 3 is statistical data of the entry/exit detection time in each home door control device 21 on a weekday at a certain station, and is an average value [second/opening/closing in each morning (early morning, morning, daytime, evening, night, midnight). ] Is shown. The boarding/alighting detection time is the cumulative time during which the detection signal output from the obstacle sensor 26 is input when the door 27 is open.

FIG. 4 shows parameters relating to the boarding/alighting time. The boarding/alighting time is the time when the door 27 of the platform door device 20 is in the fully open state.
The opening speed is the speed when the door 27 is opened. Therefore, if the opening speed is high, the time required for the opening operation of the door 27 can be shortened. The open cushion distance is the distance from the fully opened position where the vehicle decelerates at the end of the opening operation of the door 27 and transitions to a low speed when reaching the fully opened position at a low speed. Therefore, when the opening cushion distance is shortened, the low speed time in the opening operation of the door 27 is shortened, and the time required for the opening operation of the door 27 can be shortened. The opening time reference is a reference for the time required for the opening operation of the door 27 when the opening speed and the opening cushion distance are set.

The closing speed is the speed when the door 27 is closed. Therefore, if the closing speed is high, the time required for the closing operation of the door 27 can be shortened. The closing command waiting time is a waiting time from the reception of the closing command signal from the general control panel 11 until the door 27 starts the closing operation. Therefore, when the closing command standby time becomes long, it is possible to delay before the closing operation starts, and the fully open time of the door 27 becomes long. The closing time reference is a reference for the time taken for the closing operation of the door 27 when the closing speed is set.

As shown in FIG. 3, the entry/exit detection time of the home door control unit 21 (DCU#1) in the "evening" time period is "9 seconds", and the "morning" of the home door control unit 21 (DCU#40). The boarding/alighting detection time in the time zone of “” is “8 seconds”. The generation unit 24 or the generation unit 13 determines that the door 27 and the time zone in which the entry/exit detection time is 8 seconds or more is “at the time of congestion”, and generates the parameter “at the time of congestion” illustrated in FIG. 4. The generation unit 24 or the generation unit 13 determines that the door 27 and the time zone in which the entry/exit detection time is less than 8 seconds is “standard”, and generates the “standard” parameter shown in FIG. 4. When the parameter related to the entry/exit time shown in FIG. 4 is set from “standard” to “at the time of congestion”, the opening time guideline is reduced by 1 second and the closing time guideline is reduced by 1 second, so that the time taken for the opening/closing operation of the door 27 itself is reduced. Can be reduced by 2 seconds. In addition, by setting the closing command waiting time to 1 second only during congestion, the boarding/alighting time can be increased by 1 second. Therefore, the boarding/alighting time increases by 3 seconds.

(Example 2)
In Example 2 shown in FIGS. 5 and 6, the generation unit 24 or the generation unit 13 analyzes the statistical data of the number of obstacle detection operations, and shortens the recovery time from the obstacle detection operation. That is, when the number of times of obstacle detection operation in the predetermined time zone of the predetermined door 27 is larger than the predetermined number of times, the generation unit 24 or the generation unit 13 determines the time (detection time) required for the obstacle detection operation of the door 27 in the time zone. Later, the time until restoration is shortened. Therefore, it is possible to reduce a delay in train operation due to a rush-on ride.

FIG. 5 is statistical data of the number of obstacle detection operations in each home door control device 21 on Saturdays, Sundays, and holidays at a certain station, and is an average value [times for each time zone (early morning, morning, noon, evening, night, and midnight). /1 open/close]. The obstacle detection operation means that the obstacle sensor 26 detects an obstacle during the closing operation of the door 27, and then performs a reversing operation (low-speed opening operation) up to the obstacle detection reversing distance, and stops during the obstacle detection stop time. After this, it is a series of operations for restarting the closing operation.

FIG. 6 shows parameters relating to recovery from the obstacle detection operation.
The obstacle detection reversal distance is a distance moved by a determination operation that is a low-speed opening operation when the obstacle sensor 26 detects an obstacle during the closing operation of the door 27. The obstruction detection stop time is the time during which the obstruction is detected and reversed during the closing operation of the door 27 and then stopped. The number of times of abnormality determination detection is the number of times of obstacle detection for performing abnormality determination. The abnormality determination continuous detection time is a time for counting the number of times of obstacle detection for performing the abnormality determination. That is, when the number of times of detection of obstacles reaches the number of times of abnormality determination during the continuous detection time of abnormality determination, the home door control device 21 outputs an abnormality signal to the general control panel 11 and stops. Then, the platform door control device 21 is restored by an operation by a station clerk or the like or input of an opening command. If the home door control device 21 determines that there is an abnormality, an operation by a station clerk is required. Therefore, by increasing the number of detections, the number of times the home door control device 21 is stopped can be reduced.

As shown in FIG. 5, the number of times of obstacle detection operation of the home door control device 21 (DCU#1) during the "morning" time period is "0.4", and the home door control device 21 (DCU#1) ), the number of times of obstacle detection operation during the “evening” time period is “0.3 times”. Further, the number of times of obstacle detection operation of the home door control device 21 (DCU#2) in the "night" time zone is "0.2 times", and "morning" of the home door control device 21 (DCU#40). The number of times of obstacle detection operation in the time zone of is “0.2 times”. Further, the number of times of obstacle detection operation of the home door control device 21 (DCU#40) during the "evening" time period is "0.3 times". The generation unit 24 or the generation unit 13 determines that the door 27 and the time zone in which the number of obstacle detection operations is 0.2 times or more is "rushing", and generates the "rushing" parameter shown in FIG. The generation unit 24 or the generation unit 13 determines that the door 27 and the time zone in which the number of obstacle detection operations is less than 0.2 times is “standard”, and generates the “standard” parameter shown in FIG. 6. When the parameter related to the recovery from the obstacle detection operation shown in FIG. 6 is set from “standard” to “rushing”, the obstacle detection reversal distance is reduced by 300 mm, and the obstacle detection stop time is reduced by 2 seconds. Since the time of the reversing operation (opening operation) upon detection is reduced and the stop time is also reduced, the time required for the obstacle detection operation can be reduced. Further, since the number of times of abnormality determination detection is reduced by 7 and the abnormality determination continuous detection time is increased by 30 seconds, the number of times of determination of abnormality can be reduced and the number of times the operation of the home door device 20 is stopped can be reduced.

Next, the opening/closing control of the door 27 by the home door control device 21 will be described with reference to FIG. 7.
As shown in FIG. 7, it is assumed that the door 27 of the home door device 20 is in the fully open state (step S11). When opening the door 27, the drive unit 22 of the home door control device 21 opens and closes the door 27 by controlling the open drive of the motor 28 with the open speed and the open cushion distance that are the parameters stored in the storage unit 23. Let

Then, the platform door control device 21 determines whether or not there is a close command (step S12). That is, since the door 27 is in the fully open state, the home door control device 21 waits for a closing operation instruction. Then, when it is determined that there is no closing command (step S12: NO), the home door control device 21 determines whether or not there is detection of a passenger (step S19). That is, if there is no detection signal input from the obstacle sensor 26, the platform door control device 21 determines that there is no passenger detection (step S19: NO), and proceeds to step S11.

On the other hand, if there is a detection signal input from the obstacle sensor 26, the platform door control device 21 determines that a passenger is detected (step S19: YES), and integrates the boarding/alighting detection time (step S20). That is, the platform door control device 21 measures the time taken for the passengers to get on and off by accumulating the boarding/alighting detection time while the detection signal is input. Then, the platform door control device 21 proceeds to step S11 and repeats until there is a close command.

Further, when it is determined that there is a close command (step S12: YES), the home door control device 21 closes the door 27 (step S13). That is, the platform door control device 21 waits for a closing command waiting time which is a parameter stored in the storage unit 23. Then, the drive unit 22 closes the door 27 by controlling the motor 28 to close and drive at the closing speed of the parameter stored in the storage unit 23.

Subsequently, the home door control device 21 determines whether or not the door 27 is in the fully closed state (step S14). That is, the home door control device 21 confirms whether or not the closing operation of the door 27 is completed. Then, when determining that the door 27 is not in the fully closed state (step S14: NO), the home door control device 21 determines whether or not an obstacle is detected (step S21). That is, the platform door control device 21 detects an obstacle and confirms whether or not the closing operation shifts to the obstacle detection operation. Then, when it is determined that the obstacle is not detected (step S21: NO), the platform door control device 21 proceeds to step S13 and continues the closing operation.

On the other hand, when the home door control device 21 determines that an obstacle is detected (step S21: YES), the platform door control device 21 integrates the number of obstacle detection operations (step S22). Subsequently, the home door control device 21 reverses the door 27 (step S23). That is, since the home door control device 21 detects an obstacle, the home door control device 21 reverses the door 27 from the closing operation to the opening operation, and avoids the collision or the trapping between the door 27 and the obstacle. Subsequently, the home door control device 21 stops the movement of the door 27 (step S24). That is, the drive unit 22 of the home door control device 21 controls the motor 28 to open and drive to the obstacle detection reversal distance, which is the parameter stored in the storage unit 23, and then the obstacle that is the parameter stored in the storage unit 23. The drive is stopped during the detection stop time, the process proceeds to step S13, and the closing operation is restarted.

When the home door control device 21 determines that the door 27 is in the fully closed state (step S14: YES), the door 27 is in the fully closed state (step S15).
Subsequently, the platform door control device 21 transmits the entry/exit detection time (step S16). That is, the platform door control device 21 transmits the boarding/alighting detection time accumulated in step S20 to the general control panel 11. The integrated control panel 11 can determine whether or not it is congested by analyzing the statistical data of the entry/exit detection time transmitted from each platform door control device 21.

Then, the platform door control device 21 transmits the number of obstacle detection operations (step S17). That is, the home door control device 21 transmits the number of obstacle detection operations accumulated in step S22 to the general control panel 11. The integrated control panel 11 can determine whether or not there is a lot of rush by analyzing statistical data of the number of obstacle detection operations transmitted from each home door control device 21.

Subsequently, the platform door control device 21 discards the data (step S18) and ends the process. That is, the home door control device 21 discards the data on the entry/exit detection time and the number of obstacle detection operations when opening and closing the door 27 this time.

Next, with reference to FIG. 8, a parameter changing process by the home door control device 21 will be described.
As shown in FIG. 8, the home door control device 21 is in a parameter changeable state (step S31). That is, the platform door control device 21 performs the parameter changing process when the parameter can be changed. The parameter changeable state is a parameter for controlling the opening and closing of the door 27, and therefore is a state that does not affect the opening and closing control of the door 27 of the home door device 20, and for example, when the door 27 is in the fully closed state or when the door 27 is in the closed state. This is the time when inspections are being performed even when fully open.

Subsequently, the platform door control device 21 performs data analysis (step S32). That is, the generation unit 24 of the home door control device 21 analyzes the operation record data DE stored in the storage unit 23, and as shown in Examples 1 and 2, the door 27 is generated based on the operation record data DE. A parameter for controlling the opening and closing of is generated.

Then, the platform door control device 21 determines whether or not there is a parameter to be changed (step S33). That is, the generation unit 24 can determine whether or not there is a change depending on whether or not the generated parameter is different from the parameter stored in the storage unit 23. Then, when the generation unit 24 determines that there is no parameter to be changed (step S33: NO), there is no need to change the parameter and the process ends.

On the other hand, when the generation unit 24 determines that there is a parameter to be changed (step S33: YES), the generation unit 24 changes the target parameter (step S34). That is, the generation unit 24 rewrites the parameters stored in the storage unit 23 and ends the process.

Similarly, referring to FIG. 9, the parameter changing process by the general control panel 11 will be described.
As shown in FIG. 9, the general control panel 11 is in a parameter changeable state (step S41). That is, the integrated control panel 11 performs a parameter changing process when the parameter can be changed. The parameter changeable state is a parameter for controlling the opening and closing of the door 27, and therefore is a state that does not affect the opening and closing control of the door 27 of the home door device 20, and for example, when the door 27 is in the fully closed state or when the door 27 is in the closed state. This is the time when inspections are being performed even when fully open.

Then, the integrated control panel 11 performs data analysis (step S42). That is, the generation unit 13 of the integrated control panel 11 analyzes the operation record data DE stored in the storage unit 12, and as shown in Examples 1 and 2, the generation unit 13 of the door 27 is based on the operation record data DE. Generates parameters for open/close control.

Then, the integrated control panel 11 determines whether or not there is a parameter to be changed (step S43). That is, the generation unit 13 can determine whether or not there is a change depending on whether or not the generated parameter is different from the parameter stored in the storage unit 12. When the generation unit 13 determines that there is no parameter to be changed (step S43: NO), it does not need to be changed, and the process ends.

On the other hand, when the generation unit 13 determines that there is a parameter to be changed (step S43: YES), it changes the target parameter (step S44). That is, the generation unit 13 rewrites the parameters stored in the storage unit 12 and ends the process. Then, the integrated control panel 11 transmits the parameter data DP to the home door control device 21 controlled by the target parameter. The home door control device 21 rewrites the parameters stored in the storage unit 3 into the received parameter data DP.

As described above, according to this embodiment, the following effects can be obtained.
(1) Since the door 27 is opened and closed by the parameter generated by the generation unit 24 based on the operation record of the door 27 stored in the storage unit 23 of the home door control device 21, it does not require the hands of workers such as workers. The parameters of the door 27 of the home door device 20 can be set according to the situation.

(2) Since the door 27 of each home door device 20 is opened/closed by the parameter generated by the generation unit 13 based on the operation record of the door 27 stored in the storage unit 12 of the integrated control panel 11, a person such as an operator It is possible to set the parameters of the door 27 of the home door device 20 according to the situation without using the hand.

(3) In the same situation in the past, there is a high possibility that the passengers will have the same use situation, so that the home door apparatus 20 can be operated appropriately based on such operation record. Moreover, since it is highly possible that the passengers will have the same usage status according to the station and train type, the platform door apparatus 20 can be operated appropriately based on such operation record.

(5) Since the integrated control panel 11 stores the operation results of the doors 27 of the respective home door devices 20 and generates the parameters for operating the doors 27 of the respective home door devices 20, the home door devices 20 are set for each station 1. It can be operated depending on the situation.

(Second embodiment)
Hereinafter, a second embodiment of the platform door system will be described with reference to FIGS. 10 and 11. The home door system of this embodiment is different from that of the first embodiment in that the central control room 2 generates parameters of the home door device 20. Hereinafter, differences from the first embodiment will be mainly described.

As shown in FIG. 10, the platform door system 100 includes a central control room 2 that controls an integrated control panel 11 installed at each station 1. Each integrated control panel 11 is connected to the central control room 2. Each integrated control panel 11 periodically transmits the operation record of each home door device 20 connected to each integrated control panel 11 to the central control room 2.

The central control room 2 includes a storage unit 3 that stores information about each platform door device 20. The storage unit 3 stores parameter data DP for controlling the door 27 by each home door control device 21 (DCU#1, DCU#2,..., DCU#N) and each home door control device 21 (DCU#1, DCU#). 2,..., DCU#N) and stores the operation result data DE and the like. The parameter data DP may be parameters for each platform door device 20 and each time slot, parameters for each platform unit and each time slot, or parameters for each station and each time slot.

The central control room 2 includes a generation unit 4 that generates parameters for controlling the opening and closing of the door 27 by each home door control device 21 (DCU#1, DCU#2,..., DCU#N). The generation unit 4 determines each home door control device 21 (DCU#1, DCU#2) based on the operation result data DE acquired from each home door control device 21 (DCU#1, DCU#2,..., DCU#N). ,..., DCU#N) generates parameters for controlling opening/closing of the door 27. For example, the generation unit 4 analyzes the past operation results acquired from the respective home door control devices 21 (DCU#1, DCU#2,..., DCU#N) to easily delay the operation of the train door 27 or The time zone is specified, and an appropriate parameter is generated for each door 27 and each time zone.

The generation unit 4 rewrites the parameter data DP in the storage unit 3 when the parameter data DP stored in the storage unit 3 includes a parameter that needs to be changed. Then, the parameter data DP corresponding to each home door control device 21 (DCU#1, DCU#2,..., DCU#N) is transmitted to the general control panel 11. The general control panel 11 transmits the received parameter data DP to each home door control device 21 (DCU#1, DCU#2,..., DCU#N). Each home door control device 21 (DCU#1, DCU#2,..., DCU#N) stores the parameter data DP acquired from the general control panel 11 in the storage unit 23. That is, the central control room 2 can set the parameters of the door 27 of the home door device 20 according to the situation by generating and automatically updating the parameters based on the operation record of each home door device 20.

The parameter changing process by the central control room 2 will be described with reference to FIG. 11.
As shown in FIG. 11, it is assumed that the central control room 2 is in a parameter changeable state (step S51). That is, the central control room 2 performs the parameter changing process when the parameter can be changed. The parameter changeable state is a parameter for controlling the opening and closing of the door 27, and therefore is a state that does not affect the opening and closing control of the door 27 of the home door device 20, and for example, when the door 27 is in the fully closed state or when the door 27 is in the closed state. This is the time when inspections are being performed even when fully open.

Subsequently, the central control room 2 analyzes the data (step S52). That is, the generation unit 4 of the central control room 2 analyzes the operation record data DE stored in the storage unit 3 to analyze the operation record data DE so that the door 27 of the door 27 can be operated based on the operation record data DE as shown in Examples 1 and 2. Generates parameters for open/close control.

Subsequently, the central control room 2 determines whether or not there is a parameter to be changed (step S53). That is, the generation unit 4 can determine whether or not there is a change depending on whether or not the generated parameter and the parameter stored in the storage unit 3 are different. Then, when the generation unit 4 determines that there is no parameter to be changed (step S53: NO), there is no need to change the parameter and the process ends.

On the other hand, when determining that there is a parameter to be changed (step S53: YES), the generation unit 4 changes the target parameter (step S54). That is, the generation unit 4 rewrites the parameters stored in the storage unit 3. Then, the central control room 2 transmits the parameter data DP to the general control panel 11 of the station 1 in which the home door control device 21 controlled by the target parameter is provided, and the processing ends. The integrated control panel 11 transmits the received parameter data DP to the home door control device 21. The home door control device 21 rewrites the parameters stored in the storage unit 23 into the received parameter data DP.

As described above, according to this embodiment, the following effects can be obtained in addition to the effects (1) to (5) of the first embodiment.
(6) In order to store the operation record of the door 27 of each home door apparatus at each station and generate the parameter for operating the door 27 of each home door apparatus 20 at each station 1, the home door apparatus 20 is changed to the situation for each route. Can be operated accordingly.

It may be generated at the second timing so that the width is less than the predetermined value. In this way, the change width of the generated parameter is suppressed to be less than the predetermined value, so that it is possible to prevent the user from feeling uncomfortable due to a large change.

In each of the above-described embodiments, the operation record is input to the model in which the generation unit 24, the generation unit 13, and the generation unit 4 have learned in advance by artificial intelligence the relationship between the parameter and the operation record when the operation is performed using the parameter. The result obtained in this way may be used as a parameter. By doing so, the platform door device 20 can be operated more preferably.

The above-mentioned examples 1 and 2 are merely examples, and the combination of the type of operation record data DE to be acquired, the determination threshold value, the number of determination steps, and the parameter to be changed can be arbitrarily selected.
For example, in Example 2, instead of acquiring the data of the obstacle detection operation frequency of each door 27, the data of the time from the closing command input of each door 27 until the door 27 is fully closed is acquired. Good.

In the first embodiment, each home door control device 21 (DCU#1, DCU#2,..., DCU#N) includes the generation unit 24, but any of the home door control devices 21 generates the generation unit 24. 24 may be provided and the parameter of the door 27 of the other home door control device 21 may be generated.

It should be noted that one group may be all the home door devices 20 provided on the same platform, or may be a plurality of home door devices 20 on the same platform. Then, the control unit controls the opening and closing of the group based on the parameters generated based on the operation record of one or more doors 27 of the group.

When the obstacle sensor 26 determines that there is an area detection corresponding to a wheelchair or a stroller immediately before the closing command is input to the home door control device 21 or during the closing movement, the closing movement (including the reclosing movement after the obstacle detection) ), the sound volume at the time of detecting an obstacle may be reduced to reduce the risk of the traffic vulnerable person being caught in the door, the door 27 operating at high speed, and the intimidating feeling caused by the loud sound. In addition, since the traffic vulnerable person tends to take a long time to pass through the opening of the home door device 20, there is a high possibility that he/she is outside the obstacle detection area and on the operation track of the door 27, so that there is a risk of trapping the door. high.
