FIG.

Next, the operation of the platform fence information management device 1 having the above configuration will be described.

The general operation of the platform fence information management device 1 is as follows. That is, the platform fence information management device 1 collects operation information, control information, and environment information of the corresponding platform fence 30 by each fence information collection device 2, and distributes them to the platform information aggregation device 3 and the station information aggregation device 4. to aggregate sequentially. Furthermore, the centralized information management device 5 is notified of abnormal information among the operation information. However, operation information requiring high real-time processing is aggregated in real time, and control information and environment information requiring low real-time processing are aggregated by batch processing.

Next, the operation of the platform fence information management device 1 will be described in detail for each device.

First, fence information collection processing for collecting operation information, control information, and environment information of the corresponding platform fence 30 by the fence information collection device 2 will be described with reference to the flowchart of FIG. During the control time of the platform fence 30, the control unit 2a of the fence information collection device 2 activates the program stored in the ROM at regular intervals, for example, by an internal timer interrupt, and collects the fence information shown in FIG. Start processing.

As shown in FIG. 6, when the fence information collection process is started, the control unit 2a, more precisely, the CPU, requests the individual control device 33 of the platform fence 30 to Operation information of the fence 30 is acquired (step S01). The operation information indicates that the platform fence 30 is in one of the operating states of "stopped in closed state", "opening operation", "stopped in open state", "closing operation", and "abnormal state". is information indicating Next, the control unit 2a determines whether or not the previous motion information stored in the RAM is the same as the motion information acquired this time (step S02).

Then, if the acquired motion information is not the same as the previously acquired motion information (step S02: No), that is, if the operating state of the platform fence 30 is different from the previous time, the control unit 2a changes the acquired motion information. , and I/F 2b to the home information aggregation device 3 (step S03). At this time, as shown in FIG. 7(a), the control unit 2a generates a station ID that is identification information of the station, a platform ID that is identification information of the platform 40, a fence ID that is identification information of the platform fence 30, and a time stamp. is added to the motion information to generate transmission information, which is transmitted. In addition, for the next comparison, the previous operation information is overwritten with the acquired operation information and stored in the RAM. After that, the controller 2a proceeds to step S04.

On the other hand, if the acquired motion information is the same as the previously acquired motion information (step S02: Yes), that is, if the motion state of the platform fence 30 has not changed from the previous state, step S03 is skipped. , go to step S04.

In step S04, the control unit 2a requests the individual control device 33 of the platform fence 30 to acquire the control information of the drive motor of the platform fence 30, and stores it in the storage unit 2c.

Subsequently, the control unit 2a saves the measured values of the temperature, humidity, and vibration acceleration input from the temperature sensor 2d, the humidity sensor 2e, and the acceleration sensor 2f, that is, the environmental information of the platform fence 30, in the storage unit 2c (step S05). When saving the control information and the environment information, the time when the information was acquired is recorded and saved together. This completes one fence information collection process.

It should be noted that the fence information collection process is repeatedly executed at regular time intervals. Therefore, in the storage unit 2c of the fence information collecting device 2, the control information and environment information of the platform fence 30 are accumulated in chronological order. As a result, as illustrated in FIGS. 7B and 7C, the control information string 6 and the environment information string 7 are stored in the storage unit 3c. The control information string 6 is a set of control information accumulated along the time series. The environment information string 7 is a set of environment information accumulated along the time series. From the control information string 6, it is possible to know the magnitude of the load applied to the driving motor of the platform fence 30 or the time change of the rotation speed. From the environment information column 7, the temperature, humidity, and vibration acceleration of the environment in which the platform fence 30 is arranged can be known over time.

In addition, in FIG. 7B, the control information 6a indicates that the driving motor of the platform fence 30 is not energized at 10:32:36. The environment information 7a indicates that at 10:32:36, the temperature at the place where the platform fence 30 is installed is 25.2° C., the humidity is 60%, and the vibration acceleration of the floor surface is 0.80 gal. It shows that

Further, when the control unit 2a receives a command requesting the transmission of the control information sequence and the environment information sequence from the home information aggregation device 3, the control information sequence 6 and the environment information sequence 7 stored in the storage unit 2c , the station ID, the platform ID and the fence ID are attached to generate transmission information, and the transmission information is transmitted to the higher-level station information aggregation device 4 .

Next, the operation of the home information aggregation device 3 will be explained. When the I/F 3b receives the operation information transmitted from the fence information collecting device 2, the I/F 3b transmits an interrupt signal to the controller 3a. In response to this interrupt signal, the control unit 3a starts home operation history aggregation processing shown in FIG. That is, the home information aggregating device 3 starts the home operation history aggregating process with the arrival of the operation information as a trigger.

As shown in FIG. 8, when the platform operation history aggregation process is started, the control unit 3a acquires the operation information transmitted from the fence information collection device 2 (step S11). Next, the control unit 3a updates the home operation information by adding the acquired operation information to the operation information string stored in the storage unit 3c (step S12). The platform motion information is information collected for each platform fence 30, which is transmitted from the fence information collecting device 2 managed by the platform information collecting device 3, as shown in FIG. 9(a). In this example, operation information of platform barriers A to E is accumulated. Each piece of home motion information is composed of a string of motion information arranged in chronological order, as illustrated in FIG. 9B. That is, the platform operation information accumulated by each platform information aggregating device 3 is a set of histories of operation information along the time series of each platform fence 30 under management. In this way, the platform information aggregation device 3 aggregates the history of operation information of all the platform fences 30 under management.

Subsequently, the control unit 3a transmits the motion information acquired in step S11 to the station information aggregation device 4 (step S13), and terminates this process.

Next, the operation of the station information aggregation device 4 will be described. When the I/F 4b of the station information aggregating device 4 receives the operation information transmitted from the platform information aggregating device 3, it transmits an interrupt signal to the control unit 4a. In response to this interrupt signal, the control unit 4a activates the station operation history aggregation program stored in the ROM, and starts station operation history aggregation processing shown in FIG.

As shown in FIG. 10, when the station information collection process is started, the control unit 4a first acquires the received motion information (step S21). Next, the control unit 4a updates the station operation history by adding the acquired operation information to the station operation history stored in the storage unit 4c (step S22). The station operation history is information configured by aggregating the history of operation information of the platform fence 30 under the control of the station information aggregation device 4 managed by the station information aggregation device 4 . That is, the station information aggregating device 4 aggregates the history of the operation information of all the platform fences 30 under the control of the station information aggregating device 4 . Note that the station operation histories are summarized for each platform and for each platform fence, as illustrated in FIGS. 9A and 9B.

Next, the control unit 4a determines whether or not the acquired operation information is abnormality information indicating an abnormality of the platform fence 30 (step S23). If it is abnormal information (step S23: Yes), this abnormal information is transmitted to the centralized information management device 5 (step S24). In this way, when an abnormality occurs in any of the platform fences 30 under the control of the station information aggregation device 4, the information centralized management device 5 is notified of the occurrence of the abnormality in real time. On the other hand, if the received motion information is not abnormal information (step S23: No), step S24 is skipped and the current process is terminated.

Next, the operation of the centralized information management device 5 will be described. When the I/F 5b of the centralized information management device 5 receives the abnormality information transmitted from the station information aggregation device 4, it transmits an interrupt signal to the controller 5a. In response to this interrupt signal, the controller 5a activates the notification program stored in the ROM and starts the alarm processing shown in FIG.

As shown in FIG. 11, when the alarm process is started, the controller 5a first acquires the received abnormality information (step S31). Next, from the station ID, platform ID, and fence ID attached to the acquired abnormality information, the control unit 5a determines which station, which platform, and which number of the platform fence 30 has caused the abnormality (step S32). Moreover, when the abnormality information includes the content of the abnormality, the content of the abnormality is also determined.

Next, the control unit 5a displays the determined information on the display device 51 and emits an alarm sound from the speaker (step S33). In other words, notification processing is performed. After that, when there is an instruction to end the notification from the input device 52 (step S34: Yes), the control unit 5a ends the notification process (step S35).

As described above, the operation information of the platform fence 30 is transmitted from the fence information collection device 2 to the platform information aggregation device 3 in real time every time the content of the operation information changes. The platform information aggregating device 3 that has received the motion information transfers the motion information to the station information aggregating device 4 in real time. The station information aggregating device 4 that has received the transfer of the motion information transfers the received motion information to the centralized information management device 5 in real time when the received motion information is abnormal information. The centralized information management device 5 receives the anomaly information and reports the anomaly information. In this process, operation histories are formed in the platform information aggregation device 3 and the station information aggregation device 4 .

On the other hand, the control information and the environment information are accumulated in the fence information collection device 2, then periodically batch-processed, and sent to the platform information collection device 3, the station information collection device 4, and the information centralized management device 5 in sequence. transferred. In the process, the control information and the environment information are aggregated in the platform information aggregation device 3, the station information aggregation device 4, and the information centralized management device 5, respectively. The following describes the process by which control information and environment information are transferred and aggregated.

The control unit 3a of the home information aggregation device 3 periodically activates the home control information aggregation program according to the time schedule stored in the storage unit 3c, and starts the home control information aggregation processing shown in FIG. .

As shown in FIG. 12, when the home control information aggregation process is started, the control unit 3a determines the operation state of the platform fence 30 whose information is to be collected this time based on the operation information received immediately before. , is discriminated (step S41).

When the target platform fence 30 is in the opening/closing operation or in an abnormal state (step S41: Yes), the platform information aggregating device 3 waits for completion of the opening/closing operation or recovery from the abnormal state. This is to avoid any influence on the processing in which the fence information collecting device 2 transmits the operation information.

On the other hand, when the platform fence 30 is neither in the opening/closing operation nor in the abnormal state (step S41: No), the control section 3a transmits a command requesting the fence information collecting device 2 to transmit the control information sequence. In response to this command, the control unit 2a of the fence information collection device 2 reads out the control information string stored in the storage unit 2c, adds the station ID, platform ID, and fence ID to generate transmission information. , to the home information aggregation device 3 via the I/F 2b. The control unit 3a of the home information aggregating device 3 receives the control information string through the I/F 3b and additionally stores it in the storage unit 3c (step S42).

Next, the control unit 3a transmits a command to the fence information collecting device 2 to request transmission of the environment information string. In response to this command, the control unit 2a of the fence information collection device 2 reads out the environmental data string stored in the storage unit 2c, adds the station ID, platform ID, and fence ID to generate transmission information, It is transmitted to the home information aggregation device 3 . The control unit 3a of the home information aggregating device 3 receives the environmental data string via the I/F 3b, and additionally stores it in the storage unit 3c (step S43). Then finish the process.

The platform information aggregating device 3 repeats the platform control information etc. aggregating process for all the fence information gathering devices 2 under its control according to the schedule. As a result, the control information strings and environment information strings of all the platform fences 30 under the control of the platform information aggregating device 3 are aggregated by the platform information aggregating device 3 to form a control history and an environmental history. The sets of control information strings and environment information strings aggregated by the home information aggregation device 3 are called home control information and home environment information, respectively.

In addition, the control unit 4a of the station information aggregation device 4 periodically activates the station control information aggregation program according to the time schedule stored in the storage unit 4c, and performs the station control information aggregation processing shown in FIG. Start.

As shown in FIG. 13, when the station control information aggregation process is started, the control unit 4a of the station information aggregation device 4 first controls each platform barrier 30 under the control of the platform information aggregation device 3 to be accessed. The state is determined from the operational information being received. When any of the platform barriers 30 is in the opening/closing operation or in an abnormal state (step S51: Yes), the control unit 4a waits for the completion of the opening/closing operation or recovery from the abnormal state. This is to avoid affecting the operation information transfer operation of the home information aggregation device 3 . When none of the platform fences 30 under the control of the platform information aggregating device 3 to be accessed is in an opening/closing operation and is not in an abnormal state (step S51: No), the control unit 4a of the station information aggregating device 4 consolidates the platform information. A command is sent to the device 3 requesting transmission of home control information. The control unit 3a of the home information aggregation device 3 receives this command via the I/F 3b, reads the home control information stored in the storage unit 3c in response to the command, and It is transmitted to the station information aggregation device 4 . The control unit 4a of the station information aggregating device 4 receives the control information string via the I/F 4b, and additionally stores it in the storage unit 4c (step S52).

Next, the control unit 4a transmits a command requesting transmission of home environment information to the home information aggregation device 3. FIG. The control unit 3a of the home information aggregating device 3 receives this command via the I/F 3b, reads the home environment information stored in the storage unit 3c in response to this command, and outputs the home environment information via the I/F 3b. is transmitted to the station information aggregating device 4. The control unit 4a of the station information aggregating device 4 receives the environment information string via the I/F 4b, additionally saves it in the storage unit 4c (step S53), and finishes the process.

The station information aggregating device 4 repeats the station control information aggregating process for all platform information aggregating devices 3 under its control. As a result, control information and environment information of all platform fences 30 under the control of the station information aggregation device 4 are aggregated in the station information aggregation device 4 . Hereinafter, the collection of control information and environment information aggregated by the station information aggregation device 4 will be referred to as station control information and station environment information, respectively.

In addition, the control unit 5a of the information centralized management device 5 periodically activates the all control information etc. aggregation program according to the time schedule stored in the storage unit 5c, and executes the all control information etc. aggregation process shown in FIG. Start.

As shown in FIG. 14, when the process of aggregating all control information etc. is started, the control unit 5a of the centralized information management device 5 transmits a command requesting transmission of station control information to the station information aggregating device 4. FIG. The control unit 4a of the station information aggregation device 4 receives this command via the I/F 4b, reads the station control information stored in the storage unit 4c in response to the command, and via the I/F 4b It is transmitted to the information centralized management device 5 . The control unit 5a of the centralized information management device 5 receives the station control information via the I/F 5b, and additionally stores it in the storage unit 5c (step S61).

Thereafter, similarly, the control unit 5a sequentially transmits commands requesting transmission of the station environment information and the station operation information to the station information aggregation device 4 . The station information aggregation device 4 reads the station environment information and the station operation information stored in the storage unit 4c in response to these commands, and transmits them to the information centralized management device 5. FIG. The control unit 5a of the centralized information management device 5 receives the station environment information and the station operation information, additionally stores them in the storage unit 5c (steps S62 and S63), and finishes the process.

The information centralized management device 5 repeats the processing by the total control information etc. aggregation program for all the station information aggregation devices 4 under its control. As a result, the history of control information, environment information, and operation information of all the platform fences 30 under the control of the centralized information management device 5 is collected in the centralized information management device 5 .

In this way, the platform information aggregating device 3 and the station information aggregating device 4 store the histories of control information and environment information of all the platform fences 30 under their respective management. That is, control histories and environment histories of all platform barriers 30 under their respective management are accumulated. In addition, the centralized information management device 5 accumulates control information, environment information, and operation information of all the platform fences 30 under its control. That is, the control history, environment history, and operation history of all platform barriers 30 under its control are accumulated.

Next, referring to FIG. 15, an example of the operation of investigating the cause of an abnormality that has occurred using the information collected in this way will be described. As shown in FIG. 15, the person in charge operates the input device 52 of the information centralized control device 5, and the abnormality is detected from a certain period before the timing when the abnormality of the platform barrier 30 is detected. Search conditions for searching operation information, control information, and environment information are input (step S71). Next, the control unit 5a searches for the operation information, the control information, and the environment information stored in the storage unit 5c according to the input search conditions (step S72). Then, the control unit 5a displays the retrieved information on the display device 51 (step S73).
