Is a system for determining whether or not there is an abnormality. In particular, in the equipment monitoring system 500 of the present embodiment, when a train TR traveling in the direction of the arrow A1 as a commercial vehicle approaches the equipment EQ within a certain distance, the train TR responds to the call from the train TR side. By transmitting various data (communication data described later) such as abnormality determination data from the equipment EQ side, and the train TR side receiving the data, it is possible to perform maintenance management of track equipment using business vehicles. Here, the abnormality determination data means various data for making a determination as to whether normal or abnormal occurrence related to the operation of the equipment EQ is performed. In the present embodiment, in particular, the accumulation of the abnormality is recorded from the operation record of the equipment EQ. The abnormality determination data to be handled is the data extracted so as to include the number of times. Further, the latest record relating to abnormality and normality extracted from the operation record of the equipment EQ is also a target to be transmitted together with the abnormality determination data. Here, such data is referred to as normal/abnormality recording data. That is, in the present embodiment, the abnormality determination data and the normal/abnormality recording data are targets for transmission (communication targets) from the equipment EQ to the train TR. Also, these data are collectively referred to as communication data.

  Therefore, the equipment monitoring system 500 includes the on-site device 10 that is provided in association with each equipment EQ installed on the site and performs various processes related to the abnormality determination data, the portable communication terminal mounted on the train TR, and the like. A data collection device 20 configured to acquire the abnormality determination data transmitted from the field device 10, a single or a plurality of maintenance management units 50, and a command unit 100 for managing and controlling the abnormality determination data are provided. Note that the data collection device 20, the maintenance management unit 50, and the command unit 100, excluding the field device 10 among these, can be appropriately communicated through, for example, a network line NT for maintenance. On the other hand, the field device 10 provided at each site has only the short-distance communication function by the communication unit 13, and can communicate with the data collection device 20 at a short distance only within a predetermined distance from the installation position. Has become. In the equipment monitoring system 500 such as the turning machine TM, the track circuit TC, and the railroad crossing device RC, the equipment EQ to which data is transmitted and received may be referred to as the equipment EQ including the field device 10. Only the parts other than the field device 10 may be referred to as equipment EQ. Especially, when only the part other than the field device 10 is shown about the equipment, it may be referred to as equipment EQa (see FIG. 2).

  First, in the equipment monitoring system 500, the field device 10 is a monitor device that acquires data regarding various operations in order to monitor the presence or absence of abnormality in each equipment EQ, and as shown in FIG. A data receiving unit 11 that receives data on various operations in the equipment EQa that is the main body part excluding the field device 10, a data processing unit 12 that processes various data acquired from the data receiving unit 11, and a data collecting device 20. The communication unit 13 that is a wireless device for performing the communication of 1 and the main control unit MC for performing the operation processing of each unit.

  The data receiving unit 11 is an interface provided in the field device 10 for receiving the input of data regarding various operations related to the equipment EQ. For example, a rail moving operation in the turning machine TM as an example of the equipment EQ can be considered. The turning machine TM is, for example, an electric turning machine, and switches the course of the train at the turnout by moving the tongue rail among the basic rails and the tongue rails on the sleepers that form the turnout. It is a member. Although not shown in detail, in order to perform the above switching operation, the rolling machine TM is connected to the operation unit extending from the main body, for example, a motor, and the tongue rail in addition to the operation unit extending from the main body. It is provided with a connecting portion or a lock can or the like for fixing the position after the switching operation. In the present embodiment, various data is input to the field device 10 in order to record the operating data of each unit that constitutes these switching machines TM.

  The data processing unit 12 is an electronic circuit unit including a CPU, a storage device, and the like, and performing various types of data processing. The data processing unit 12 stores a variety of information regarding the operation of the equipment EQ received via the data receiving unit 11 as an operation record of the equipment EQ, and a data extraction for extracting abnormality determination data from the data storage unit 12a. And a portion 12b. In the present embodiment, in particular, the data storage unit 12a stores all the operation records of the equipment EQ. On the other hand, the data extraction unit 12b extracts the abnormality determination data including the abnormality record data regarding the abnormality and the normality regarding the latest operation to be transmitted and the accumulated number of abnormality. In addition, as will be described later in detail, the data storage unit provides information including accumulated data that has not yet been transmitted in the field mode for performing field confirmation. That is, the field device 10 accumulates data other than the communication data composed of the normal/abnormal recording data and the abnormal determination data in the data processing unit 12, and can provide all the data depending on the situation.

  The communication unit 13 is configured by a device for performing wireless communication with the data collection device 20. Here, for example, transmission/reception is performed in the frequency band of 920 MHz, and when there is no data communication with the data collection device 20, reception standby is performed, and only when data communication is necessary, wireless communication is performed from the standby state. It is a wake-up system that is activated by using it. In this example, the communication unit 13 is fixedly installed, for example, in the immediate vicinity of the associated equipment EQ, and can communicate within a range of about 100 m from the installation position. That is, while the data collection device 20 mounted on the train TR is within the distance of 100 m from the communication unit 13, the field device 10 and the data collection device 20 can communicate with each other.

  The main control unit MC is composed of a CPU and the like, and controls the operation of the entire field device 10 including the above units. Here, in particular, regarding the data processed by the data processing unit 12, control relating to transmission to the data collection device 20 via the communication unit 13 is performed.

  Next, in the equipment monitoring system 500, the data collection device 20 is mounted on the train TR, as described above, and is configured by, for example, a mobile communication terminal such as a smartphone. The data collection device 20 can have a communication function, a data storage function, or various operation controls, but here, in particular, has various mechanisms for enabling communication with the communication unit 13. That is, it is possible to communicate in the same frequency band (for example, 920 MHz) corresponding to the communication unit 13. In particular, in the present embodiment, a polling answer type response in which the data collection device 20 is the host is used. That is, the data collection device 20 inquires with respect to a plurality of field devices 10 (communication unit 13) existing along the line RL whether or not there is data to be transmitted at a fixed timing, and transmits/receives when the condition is satisfied. It is in the form. The data collection device 20 receives the latest abnormality determination data from each field device 10 in the built-in storage and also stores the abnormality determination data received in the past, and stores the latest normal/abnormality recording data and abnormality determination data. It is possible to compare the accumulated normal/abnormal recording data and abnormal determination data in the past. The data collection device 20 can use the communication function to provide these pieces of information to the maintenance management unit 50 and the command unit 100.

  Returning to FIG. 1, in the equipment monitoring system 500, the maintenance management unit 50 has, for example, one or a plurality of routes on which the train TR equipped with the data collection device 20 travels, or a part of the routes as a jurisdiction section, Responsible for the maintenance and management of each facility on the section under its jurisdiction. Therefore, the maintenance management unit 50 includes, for example, the collection terminal 20A, the data collection server 30, and the display device 40 in order to grasp the status of each facility. The collection terminal 20A is capable of communicating with the data collection device 20 that collects data in the section managed by the maintenance management unit 50, or is the data collection device 20 itself. The data collection server 30 acquires data from the collection terminal 20A and manages and stores the data. Further, the display device 40 displays various data stored in the data collection server 30. Thereby, for example, the administrator of the maintenance management unit 50 can visually recognize the status of the controlled area. Note that the maintenance management unit 50 is not limited to a single unit, and a plurality of units may be provided to perform the management as described above for each jurisdiction section. Further, the maintenance management unit 50 accepts a command from the command unit 100 via the maintenance network line NT or the like, and when an emergency repair is required in a section under the jurisdiction, the maintenance management unit 50 notifies the manager to that effect. Is notified.

  Finally, in the equipment monitoring system 500, the command unit 100 receives various data from the data collection device 20 and the maintenance management unit 50 via the network line NT or the like, and detects the data of the lines under the monitoring of the equipment monitoring system 500. Perform comprehensive management (management control) for all sections. Therefore, the command unit 100 includes a management device 110 including a display unit and the like. That is, the supervisor in the command unit 100 can visually recognize the situation of all sections. The command unit 100 determines the situation from various data from the data collection device 20 and the maintenance management unit 50, and particularly in the case of an urgent need, maintenance management that controls the relevant section via the network line NT or the like. The unit 50 is informed of that fact. It should be noted that the above judgment may be performed by a supervisor, that is, a person, but for example, while urgent repair items are set in advance, an abnormality occurs when the abnormality determination data is transmitted from the field device 10. By including the information of the type of abnormality occurrence in each equipment EQ in the discrimination data, it is possible for the management device 110 to automatically determine whether or not the abnormality occurrence corresponds to urgent repair matters. You can

  With the above-described configuration, the equipment monitoring system 500 can reliably perform abnormality determination in each piece of equipment on the track on which the train TR travels.

  Here, for traveling of a commercial vehicle, for example, the maximum speed is set to 130 km/h. When attempting to collect various kinds of information using a train (business vehicle) traveling at high speed in this way, there is a possibility that a large amount of capital investment or the like will be required. Further, it may be difficult to transmit and receive a large amount of data in a short time in a quiet area or an area where there is a speed limitation in wireless communication by mobile communication of wireless communication.

  On the other hand, in the present embodiment, as described above, communication is performed between the field device 10 provided in the field and the data collection device 20 mounted on the train TR, and the field device 10 side is normal or abnormal. By suppressing the amount of data to be transmitted and received by judging whether or not it is possible to reliably acquire data regarding abnormalities with a simple configuration, and by doing so, for example, by reducing the number of periodic inspections, The number of personnel is reduced during maintenance, and the labor shortage can be resolved.

  Hereinafter, an example of communication between the field device 10 and the data collection device 20 in the equipment monitoring system 500 will be described with reference to FIG.

  As shown in the figure, the plurality of field devices 10 or the communication unit 13 constituting the plurality of field devices 10 are provided for each equipment EQ such as the turning machine TM, and are provided beside the line RL. When each communication unit 13 is within the communicable range CC of the data collection device 20 mounted on the traveling train TR, that is, when the distance to the data collection device 20 is within 100 m, the data collection device 20 determines that the corresponding communication unit 13 is present. The communication with the field device 10 configured as above is started, and the normal/abnormal recording data and the abnormal determination data are collected. As shown in the figure, when the plurality of communication units 13 can communicate with the data collection device 20, the data collection device 20 sequentially turns on the field device 10 (communication unit 13) at a fixed timing. By inquiring, interference can be avoided.

  Here, as described above, when the data collection device 20 is installed in the train TR that travels at a commercial speed (for example, a maximum speed of 130 km/h), the communicable range is about 100 m. The shortest possible time is about several seconds, and the amount of information that can be communicated between the data collection device 20 and the field device 10 in one pass of the train TR is, for example, several hundred bytes of information depending on the communication method. May be limited to three times and transmitted. In the present embodiment, in consideration of such a situation, the normal/abnormal recording data and the abnormality determination data are extracted in advance from the operation record of the equipment EQ so as to be within the limited information amount (data amount). By causing the data collection device to acquire the abnormality determination data when passing through the train TR, it is sufficient even under severe conditions such as communication being limited within a predetermined distance/short time within a predetermined time. It can be configured in various ways.

  FIG. 4 is a conceptual diagram for explaining an example of data storage in the field device 10. More specifically, the data DT1 conceptually shows a state of data stored in a memory corresponding to the data storage unit 12a of the data processing unit 12. As described above, in the example here, the data storage unit 12a accumulates and stores all the data regarding each operation. In the illustrated example, the data DT1 includes normal data storage area data DT1a that stores data in the case of normal operation and abnormal data storage area data DT1b that stores data in the case of abnormal operation (abnormal data). It is composed of. Here, as an example, in the data DT1, the latest 450 cases of data (normal data) can be stored in the normal data storage area data DT1a, and the latest 50 pieces of abnormal data storage area data DT1b can be stored. Minute data (abnormal data) can be stored. On the other hand, in the data extraction unit 12b of the data processing unit 12, the normal/abnormal recording data, which is a record related to the latest (latest) abnormality and normal among the data accumulated as the data DT1, information on the cumulative number of abnormalities, and The abnormality determination data including the information on the type of abnormality occurrence is set as the latest one data that can be communicated in one pass and is extracted as the communication data JD1 to be transmitted to the data collection device 20. That is, the communication data JD1 constitutes information that enables the data collection device 20 or the command unit 100 (see FIG. 1) that receives data from the data collection device 20 to determine whether there is an abnormality (failure analysis). Further, as shown in the figure, the communication data JD1 is transmitted in a state of being divided into three divided data DV1 to DV3, for example, data of several hundred bytes each, as shown in the figure. There is.

  Hereinafter, with reference to FIG. 5 and the like, an example of the turning machine TM as the equipment EQ that is the target of the abnormality determination according to the present embodiment will be described. FIG. 5 is a conceptual plan view showing the outline of the internal configuration of the casing SC of the turning machine TM.

  First, as illustrated in FIG. 5, a main body portion 10A for accommodating each portion of the field device 10 other than the communication portion 13 is provided substantially in the center of the inside of the housing SC for accommodating the respective portions of the turning machine TM. The cable CB1 connected to the main body 10A extends to the outside of the casing SC of the rolling machine TM and is connected to the communication unit 13. As described above, the field device 10 is attached to the rolling machine TM. The main body 10A is in a state in which, for example, four corners of a top plate of a rectangular parallelepiped storage section are fastened with bolts, the main body section 10A is fixed to the casing SC of the rolling machine TM, and the lid is covered. In addition, since the cable CB2 of the field device 10 is connected to the power supply unit PS of the rolling machine TM, the electric power of each unit configuring the field device 10 is secured.

  Hereinafter, with reference to FIG. 6 and the like, an example of a method of acquiring data by the field device 10 when the rolling machine TM among the units of the rolling machine TM is operated will be described. FIG. 6 is a block diagram conceptually showing an example of the internal configuration of the turning machine TM. As shown in the figure, the turning machine TM, which is an electric turning machine, includes a power supply section PS for operating each section in the housing SC, as well as, for example, a turning machine circuit TMc and a motor section TMm. And so on. The power supply section PS is connected to the rolling machine internal circuit TMc to supply electric power, and the rolling machine internal circuit TMc supplies electric power to the motor section TMm and the like constituted by the motor terminal board and the motor. Various operation controls are performed. In the above, the main body unit 10A that houses each unit other than the communication unit 13 in the field device 10 functions as a sensor terminal for monitoring the operation of the rolling machine TM. Describing more specifically with reference to the illustrated example, the main body section 10A of the field device 10 is provided with a split type (clamp type) measuring section CL1, CL2 between the power source section PS and the in-machine circuit TMc. Alternatively, it is possible to measure or calculate a current value or a voltage value between the switching in-machine circuit TMc and the motor section TMm. In addition, by making the measuring units CL1 and CL2 a split type (clamp type), it is possible to perform the measurement by the field device 10 without changing the wiring on the side of the turning machine TM. Further, the data processing unit 12 (see FIG. 2) included in the main body unit 10A also acquires the current value and the voltage value as described above or the respective values derived therefrom, as well as the data regarding the time. As described above, for example, the data processing unit 12 can acquire various data such as the motor voltage value, the motor current value, the control relay voltage value, and the conversion time at the time of conversion as the operation record of the switching machine TM. The data extraction unit 12b of the data processing unit 12 extracts the abnormality determination data based on a change in any of the values of these various data that can be acquired or the values calculated by the combination thereof. In this case, it is possible to cause the data collection device 20 to acquire particularly important information or information that requires urgent attention as an abnormality of the rolling machine TM. In the above description, the combination of various data includes not only a combination using all of the various data but also a combination using only a part of the various data.

  Hereinafter, various data stored in the field device 10 and various data transmitted to the data collecting device 20 will be described with reference to FIG. 7. Of FIG. 7, FIG. 7A is a data table showing an example of the contents of the data part regarding the operation of the rolling machine TM in the format data in the rolling machine TM, and FIG. 7B is It is a data table which shows an example of the electronic message format used as the transmission object to the data collection device 20 about the turning machine TM. First, as illustrated in FIG. 7A, here, in order to capture a dynamic change in the conversion operation of the continuously operating switching machine TM, for example, the sampling time is set to 50 mm seconds as a unit and the motor voltage is sequentially increased. The value and the current value are measured. All of these data are recorded in the data storage unit 12a together with the time information of the conversion operation and the like. Here, in the above case, for example, if it takes 5.5 seconds on average for one conversion operation in the switch TM, the motor voltage value and the current value are measured 110 times. The amount of data for each value is 2 bytes, and in addition to the information about the time, the data of the cumulative number of times and the information of the type of abnormality occurrence, and when the measurement time of the disturbance current is added, it will start from several hundred bytes. It is considered that the amount of information of about one thousand and several hundred bytes is necessary. In the present embodiment, by transmitting these pieces of information in the state of being divided into three in units of several hundred bytes, it is possible to reliably transmit to the data collection device 20 during a short communication time. The message format for the data collection device 20 is, for example, as shown in FIG. 7(B).

  Hereinafter, an example of the operation of the equipment monitoring system 500 will be described with reference to FIG. 8 and the like. FIG. 8 is a conceptual diagram for explaining an example of the operation of the equipment monitoring system. Here, the train TR equipped with the data collection device 20 departs from station A and heads in the direction of arrow A1 toward station B. It shows how to get to. Here, as shown in the figure, a plurality of equipments EQ in which the field device 10 to be communicated with the data collection device 20 is installed are equipments EQ1, EQ2,... EQn along the line RL in the order from the A station. It is installed side by side with... In the data collection device 20, information about the installation positions of the station A, that is, the installation positions of the field devices 10 is stored in advance in the A station. Further, the train TR is provided with a position detection device PD that detects the current position of the train TR. Therefore, the data collection device 20 can acquire the information on the installation position of each field device 10 and the information on the current position of the train, and starts communication with each field device 10 based on these information. ing. As a result, the data collection device 20 can perform the communication operation at a more appropriate timing as the host when the plurality of data collection devices 20 perform communication. That is, it is possible to specify the equipment EQ existing within the communicable range and call a response to them. Various types of position detecting devices PD are conceivable. For example, a device having a GPS function, a device that measures a moving distance based on the rotation speed of the wheels of the train TR, and the like are assumed.

  Hereinafter, with reference to the flowchart of FIG. 9, an operation example of the data collection device 20 configuring the facility monitoring system 500 in the mode illustrated in FIG. 8 will be described. First, when the train TR departs from the A station, the data collection device 20 detects the position of the train TR by using the position detection device PD (step S101) and determines whether or not the train TR has arrived at the destination, that is, the B station. Confirm (step S102). When it is determined in step S102 that the data has not arrived at the B station (step S102: No), the data collection device 20 is within the communicable range based on the information of the installation position of each field device 10 stored in advance ( For example, it is confirmed whether or not the equipment EQ to be communicated exists within 100 m from the detected position of the train TR (step S103). When it is determined in step S103 that the equipment EQ does not exist within the communicable range (step S103: No), the data collection device 20 detects the position of the train TR again (step S101).

  On the other hand, when it is determined that the equipment EQ exists within the communicable range in step S103 (step S103: Yes), the data collection device 20 sends an information request signal to the equipment EQ (field device 10). It is transmitted (step S104) and a reply confirmation is performed (step S105). The data collection device 20 continues the operation of transmitting the information request signal and confirming the reply until a predetermined time has elapsed (steps S104 to S106). In addition, when there is no response from the equipment EQ even after the lapse of a predetermined time (step S106: Yes), the data collection device 20 determines that the equipment EQ is in a state of being incommunicable, and as a notification to that effect, Communication abnormality notification is performed (step S107). Although various methods and destinations of communication abnormality notification by the data collection device 20 are conceivable, for example, by using a mobile communication line, the data collection server 30 of the maintenance management unit 50, and further the command unit 100. It is conceivable to notify the management device 110 (see FIG. 1).

  If the reply to the information request signal is confirmed in step S105 (step S105: Yes), the data collection device 20 communicates with the data, that is, the abnormality determination data and the normal/abnormal recording data from the corresponding field device 10. Data is acquired (step S108), the latest abnormality determination data acquired in the most recent communication with the field device 10 among the acquired data, and the past abnormality of the field device 10 already accumulated in the data collection device 20. The abnormality determination data is compared (step S109). The data collection device 20 determines whether or not an abnormality has occurred in the equipment EQ corresponding to the field device 10 based on the comparison result in step S109 (step S110). For example, the presence/absence of an abnormality is determined from the change in the cumulative number of times of abnormality included in the abnormality determination data.

  As a result of the determination in step S110, if it is determined that there is no abnormality in the corresponding equipment EQ (step S110: No), that is, there is no change in the cumulative number of abnormality times in the latest abnormality determination data, and the latest data is also normal. If it is within the range, the data collection device 20 notifies that it is normal (step S111). On the other hand, if it is determined from the latest abnormality determination data that the facility EQ has an abnormality (step S110: Yes), the data collection device 20 notifies that an abnormality has occurred (step S112). Regarding the notification in step S111 or step S112, various notification modes can be considered as in the case of step S107.

  After the processing in step S107, step S111, or step S112, the data collection device 20 repeats the operation from the position detection of the train TR in step S101 again and arrives at the B station (step S102: Yes). The above operation is repeated.

  It should be noted that, in the above, for simplification of the description, the description has been made on the relation between the one equipment EQ or the field device 10 corresponding thereto and the data collecting device 20, but the data collecting device 20 is almost the same as described above. It is possible to communicate with a plurality of field devices 10 at the same time. For example, by performing high-speed communication with 10 field devices 10 in sequence, substantially simultaneous communication is possible. In the present embodiment, as described above, the polling answer type response in which the data collection device 20 is the host is used to make an inquiry to the field device 10 at a fixed timing.

  Next, with reference to the flowchart of FIG. 10A, an example of the process of recording the operation of the equipment EQ in the field device 10 that constitutes the equipment monitoring system 500 will be described. Here, a process for one piece of equipment EQ (for example, equipment EQn) in the mode illustrated in FIG. 8 will be described. In the following description, the equipment EQn will be described as a rolling machine, but the same processing as in the following case is performed with other equipment.

  First, the field device 10 provided in the turning machine as the equipment EQn continues to check whether the conversion operation, that is, the rail switching (path switching) operation, which is the operation in the equipment EQn, has been started (step S201). ). When the start of the rail switching operation is confirmed in step S201 (step S201: Yes), the data processing unit 12 of the field device 10 starts recording the operation (step S202). The operation recording in the data storage unit 12a of the data processing unit 12 is continued until it is confirmed that the rail switching operation is completed (step S203). When the completion of the rail switching operation is confirmed in step S203 (step S203: Yes), the abnormality determination data is extracted by the data extraction unit 12b of the data processing unit 12 (step S204). When the process of step S204 is completed, a series of processes relating to the operation record of the equipment EQ is finished, and the operation from step S201 is continued again. When extracting the abnormality determination data in step S204, it is determined whether or not the operation recorded together is abnormal. Therefore, for example, in the field device 10, a threshold value is determined in advance for each numerical data such as the voltage, current, or operation time during operation in the equipment EQ for which data is to be acquired, and a value exceeding the threshold value is set. When it is detected, it is determined that there is an abnormality, and a process of increasing the count number of the cumulative abnormality number by one is performed. In this case, the data collection device 20 can determine that an abnormality has occurred by increasing the accumulated number of abnormalities. Further, by indicating which of the preset thresholds is exceeded, it is possible to create information on the type of abnormality occurrence in the equipment EQ.

  Hereinafter, with reference to the flowchart of FIG. 10B, an operation example of the response of the field device 10 to the data collection device 20 will be described. The field device 10 repeats the operation of extracting (creating) the abnormality determination data described with reference to the flowchart of FIG. 10A for each conversion operation of the turning machine, while determining the abnormality from the data collection device 20. When there is a data transmission request, the operation for responding to this is performed. That is, the field device 10 continues to confirm whether the information request signal is received from the data collection device 20 via the communication unit 13 (step S301), and when the reception of the information request signal is confirmed (step S301). (Step S301: Yes), the extracted normal/abnormal recording data and abnormality determination data are read from the data extracting unit 12b (Step S302), and transmitted to the data collecting device 20 via the communication unit 13 (Step S303), The operation from step S301 is continued again.

  As described above, in the facility monitoring system 500 according to the present embodiment, in the field device 10, the abnormality determination data including the record regarding the latest abnormality and normality and the accumulated number of abnormalities is extracted from the operation record of the facility EQ. Incidentally, by causing the data collection device 20 to acquire the abnormality determination data, it is possible to maintain reliable exchange of data necessary for abnormality determination while reducing the amount of data during communication, and reduce the number of personnel during maintenance. The shortage can be resolved. Furthermore, by suppressing the amount of data to be transmitted and received, the communication between the data collection device 20 and the field device 10 can be configured sufficiently even during a short time within a predetermined distance, and the cost of communication equipment can be suppressed.

  Hereinafter, with reference to FIG. 11 and the like, an example of the processing after the abnormality in the equipment EQ is confirmed in the data collection device 20 will be described. In the above aspect, even if an abnormality occurs, depending on the degree of the abnormality, immediate action may be required or may not be so urgent. In the above, it is considered as a typical example to judge the urgency of the measures depending on the type of abnormality occurrence. When urgency is not required, for example, it may be possible to normalize the abnormality together with the minimum required maintenance (for example, regular mechanical oiling for maintenance of operation). Be done. On the other hand, in the case of an urgent matter, repair personnel will be immediately sent to the site where the equipment is installed. Here, as described above, the mode in which the abnormality determination data of the business vehicle in the normal train operation state is acquired is referred to as the business vehicle mode or the normal operation mode. The mode in which repair personnel are directed to the site based on the detection of the field check to confirm the site is called the field mode.

  FIG. 11 is a conceptual diagram for explaining switching to a site mode in which site confirmation is performed. First, in the commercial vehicle mode (normal operation mode), as shown by an arrow C1 in FIG. 11, the data collection device 20 installed in the train TR via the field device 10 (communication unit 13) provided in the equipment EQ is used. The abnormality determination data is acquired and transmitted to the maintenance management unit 50 and the command unit 100.

  On the other hand, as indicated by an arrow C2 in FIG. 11, when the command unit 100 determines that it is urgent due to the content of the abnormality determination data and it is determined that the repair personnel should be sent to the site, that fact is notified. The information is transmitted to the maintenance management unit 50 that puts the facility that requires urgent control under its jurisdiction, and the maintenance management unit 50 switches to the site mode in which the site confirmation is performed toward the installation location. At this time, from the maintenance management unit 50, a person for eliminating the abnormality, that is, a worker for repairing the failure is sent, and also the collecting terminal 20A is carried to the on-site apparatus 10 by the collecting terminal 20A. It is possible to obtain all the data related to the saved operation records. The collection terminal 20A is, for example, a mobile communication terminal, and more specifically, the data collection device 20 itself, or a device capable of transmitting and receiving in the frequency band of 920 MHz like the data collection device 20. It is applied, and the data of the operation record can be exchanged via the communication unit 13 by wireless communication. In the case of wireless communication in the field mode, unlike communication in the commercial vehicle mode (normal operation mode), there is no restriction on the communication time, so a large amount of data can be exchanged. In addition, regarding the above aspect, in other words, from the side of the field device 10, the data storage unit 12a of the data processing unit 12 records the operation record of the equipment EQ when the business vehicle mode (normal operation mode) is switched to the site mode. Information including untransmitted data is provided to the collection terminal 20A, which is a data collection device. As described above, in the field mode, detailed data can be acquired when an abnormality occurs (failure occurs). Note that, as indicated by an arrow C3 in FIG. 11, all data regarding the operation record acquired by the collection terminal 20A is transmitted to the maintenance management unit 50 and the command unit 100.

  FIG. 12 is a conceptual diagram showing a configuration example of a part of the on-site device 10 for performing on-site confirmation in the on-site mode. Here, as shown in the figure, the operation terminal OT for performing various operations such as mode switching in the field device 10 functions as a sensor terminal for monitoring the operation, and particularly, as an interface for accepting an operation, It is assumed to be installed. The operation terminal OT has, in addition to the mode changeover switch SW1 for switching various modes including the mode switching between the on-site mode and the normal operation mode, in order to exert the function for performing various operations in the on-site mode, for example, A threshold value setting switch SW2 for setting various threshold values, a segment display section SS, an abnormality occurrence display lamp LA1, an operation confirmation lamp LA2 and the like are provided. The threshold value setting switch SW2 is for setting various threshold values as a reference for determining whether or not the measurement result of each value is abnormal. For example, when the equipment EQ is an electric switch, it is conceivable that the thresholds of the voltage, the current, and the conversion time at the time of conversion can be set by operating the threshold setting switch SW2. The segment display section SS is composed of, for example, a 4-digit 7-segment LED, and displays the status of the operation of each of the switches SW1 and SW2. More specifically, the segment display section SS can display the content according to the switching of the values for displaying the mode, the voltage, the current, etc. by the switches SW1 and SW2. It is also possible to adopt a mode in which the display on the segment display section SS is automatically switched, for example, every few seconds. The abnormality occurrence indicator lamp LA1 is, for example, an LED lamp or the like, and is an abnormality occurrence indicator lamp that changes the display state when it is determined that an abnormality has occurred in the field device 10. Regarding how to change the display state, for example, it is turned off when it is normal and lights up when it is determined that an abnormality has occurred, or the color changes between normal time and abnormal time, or blinking display, etc. Can be considered. Further, the operation confirmation lamp LA2 is composed of, for example, an LED lamp or the like, and is for indicating that the function of the operation terminal OT itself, the field device 10 in which the operation terminal OT is incorporated, and the equipment EQ are operating normally. Is. That is, the operation confirmation lamp LA2 is a self-health indicator lamp that displays the soundness of its function. Regarding the display mode of the operation confirmation lamp LA2, various modes are conceivable as in the case of the abnormality occurrence display lamp LA1.

  In addition to the above, the operation terminal OT also has a power supply line LL1 for securing a power supply, a communication line LL2 for enabling wired or wireless communication with each unit of the field device 10, and for transmitting an abnormality to the outside. The alarm contact LL3 and the like are provided. The alarm contact LL3 is turned off (open) when an abnormal value is discriminated during measurement of the field device 10, for example, and transmits the abnormality to the outside. When performing the site confirmation in the site mode, it is highly possible that the alarm contact LL3 is OFF (open), and the operator on the site will also repair it. Further, in this case, the alarm contact LL3 operates together with the abnormality occurrence display lamp LA1 as a contact for outputting the abnormality occurrence to the outside when the abnormality occurrence in the field device 10 is determined.

  The operating terminal OT may have various configurations, and may be incorporated as a part of the main body 10A (see FIG. 5 or the like). However, for example, like the communication unit 13 (see FIG. 1), By connecting the main body of the equipment EQ to the outside by wiring, it is possible to facilitate various operations for confirming the site, or to be integrated with the communication unit 13. Although illustration is omitted, for data collection in the field mode, for example, in addition to the wireless communication data collection by the collection terminal 20A described above, for example, a slot for inserting a medium is provided in the operation terminal OT to insert the medium. It is also possible to adopt a mode in which it is automatically saved.

  Hereinafter, as one mode regarding the use of the operation terminal OT, a case will be described in which the operation terminal OT is incorporated in the field device 10 (see FIG. 5 and the like) of the turning machine TM which is one of the equipment EQ.

  In this case, first, the threshold value setting switch SW2 functions as an input receiving unit that receives a setting input of a threshold value serving as a reference for abnormality determination. More specifically, the threshold value setting switch SW2 is used as a value to be measured in the turning machine TM, for example, for each measured value such as a current value or a voltage value of the motor at the time of conversion and data related to the time associated therewith. , Accepts the setting of various thresholds that should serve as a criterion for determining normality/abnormality. Further, when setting various thresholds, the segment display unit SS functions as a set value display unit that displays the set value received by the threshold setting switch SW2.

  In addition, when it is determined that there is an abnormality in the field device 10 based on the threshold value, that is, when it is determined that an abnormality has occurred, the abnormality occurrence display lamp LA1 as the abnormality occurrence indicator lamp is activated to change the display state. In addition, the alarm contact LL3 is activated to output the abnormality occurrence to the outside. In addition, it is confirmed whether the operation of the field device 10 including the operation terminal OT and the operation of the turning machine TM are normal during the entire operation period including the above-described abnormality occurrence determination. It can be confirmed by the lamp LA2.

  Further, in the turning machine TM including the operating terminal OT, various measurement modes may be set in advance so that each measurement value in each measurement mode can be displayed. Hereinafter, an example of various measurement modes in the turning machine TM will be described. First, in the normal operation mode in the normal train operation state, the turning machine TM records the motor voltage value at the time of conversion, the motor current value, the control relay voltage, and the conversion time or within the conversion time as the operation record. Acquire various data such as maximum and minimum values. Here, the above-described normal measurement is a measurement in the normal measurement mode, which is one mode of the normal operation mode. On the other hand, for example, in the field mode where the field confirmation is performed, it may be desired to perform a measurement different from the above-described normal mode. As a typical example, it is conceivable to measure the slip current in the turning machine TM. Here, it is assumed that the mode for measuring the slip current is the slip current measurement mode as one mode in the field mode, and the mode changeover switch SW1 can switch between the normal measurement mode and the slip current measurement mode.

  The measurement of the slip current will be described below. First, as a premise, in the rolling machine TM, when the operation of the rolling machine TM is disturbed by, for example, a foreign object being caught between the basic rail and the tongue rail, the motor continues to rotate. , The clutch is designed to slip in order to protect the motor from burning. The current flowing at this time is called a slip current. By measuring the slip current, it can be confirmed that the characteristics of the electric motor and the clutch in the rolling machine TM have not changed (normal). For this reason, it is conceivable that the measurement of the slip current should be included in the items of the periodic inspection, for example. In this embodiment, for example, in the field mode, the slip current can be set to the slip current measurement mode, so that the slip current can be measured at the site.

  Regarding the measurement of slip current, it is stipulated that it be measured after a fixed time from the start of disturbance in order to stabilize the current. Therefore, for the slip current inspection, for example, a method of inserting a spanner or the like between the rails at the site and measuring the current after a fixed time can be considered. Further, in the slip current measuring mode, the sampling time and the measuring time are changed as compared with the case of the measurement in the normal measuring mode. For example, in the normal measurement mode, the sampling time is set to 50 mm seconds and the measurement time is set to 16.5 seconds in the conversion data measurement, while in the slip current measurement mode, the sampling time is set to 300 mm seconds and the measurement time is set to 16.5 seconds. 90.0 seconds. Thereby, labor saving in measurement can be achieved.

  In addition, here, each measurement value as the measurement result in the selected mode is selectively fixed (for example, only current, only voltage, etc.) in the segment display section SS as the measurement value display section, or sequentially. It may be displayed. That is, the segment display unit SS displays each measurement result such as the motor voltage value and the motor current value measured at the time of conversion by the turning machine TM, for example, every few seconds, in a predetermined order. It may be an aspect.

  In the above case, the turning machine TM can sequentially display each measurement value in one measurement mode selected from a plurality of measurement modes by the operation terminal OT.

  Further, in the operation terminal OT, the types of abnormality occurrence of the accumulated abnormality data may be displayed in the order of history. Specifically, for example, the mode changeover switch SW1 is set to be capable of switching to the abnormality history display mode for displaying the abnormality history, and when the abnormality history display mode is selected, the abnormality history display unit is selected. It is conceivable to display the types of abnormality occurrences in the order of history in the segment display section SS. In this case as well, it is conceivable that the types of abnormality occurrences that occurred in the past are displayed in order from the most recent latest abnormality occurrence type, for example, every few seconds.

  Regarding the display of each measured value and the type of abnormality occurrence or the history display on the segment display section SS, a code or the like indicating the type of measured value or the type of abnormality occurrence is determined in advance, and the measured value is displayed on the segment. It is conceivable to predetermine the type of occurrence of abnormality, the type of measured value, the position indicating the number of histories, and the like.

  Further, in the above description, various displays are performed on the segment display section SS, but the display is not limited to this, and the display may be performed in various modes. Further, in the above, the segment display section SS is not only the set value display section that displays the set value for the threshold value, but also the measured value display section that displays each measured value in the measurement mode, and further the history of the type of abnormality occurrence. Although it is also used as the abnormality history display unit for displaying in order, for example, a plurality of display units may be prepared and separately displayed according to the purpose.

  Further, in the above, the turning machine TM is exemplified as one of the equipment EQ, but the other equipment EQ also has the same aspect by variously changing the measurement content according to the attribute of the equipment EQ. It is possible.

[Second Embodiment]
Hereinafter, with reference to FIG. 13, an example will be described of a facility monitoring system according to the second embodiment or a track circuit as a facility applicable to the facility monitoring system.

  The track circuit and the equipment monitoring system including the track circuit according to the present embodiment are modifications of the equipment monitoring system illustrated in the first embodiment, and are the same as the case of the first embodiment except the details of the track circuit. Therefore, description of the entire facility monitoring system will be omitted, and only the track circuit will be described.

  FIG. 13(A) is a conceptual plan view showing a configuration example of the control device CE that operates the track circuit TC as the equipment EQ according to the present embodiment. In other words, it can be said that a detailed example of the track circuit TC as the equipment EQ shown in FIG. 1 is shown. Further, FIG. 13B is a graph conceptually showing the state of the track circuit voltage that is the measurement target. In FIG. 13B, the horizontal axis represents time and the vertical axis represents the value of the track circuit voltage.

  As shown in FIG. 13A, the track circuit TC according to the present embodiment includes a data processing unit 12 as well as a power supply unit PS for operating each unit in a housing SC that houses each unit of the control device CE. , Or a control panel CN which controls various operations. The data processing unit 12 has an abnormality determination data processing unit PP1 that performs data processing relating to abnormality determination as a part of a main part PP that processes various data. In the abnormality determination data processing unit PP1, the data collection device 20 includes The abnormality determination data to be transmitted is extracted. The extracted abnormality determination data and normal/abnormality recording data (records regarding abnormality and normality) are stored in the abnormality determination data storage unit PP2. As described above, here, the abnormality determination data processing unit PP1 and the abnormality determination data storage unit PP2 cooperate to function as a data extraction unit that extracts the abnormality determination data. The communication data including the abnormality determination data and the normal/abnormality recording data is transmitted from the abnormality determination data storage unit PP2 to the data collection device 20 via the communication unit 13 which is a communication terminal.

  Here, as shown in the graph of FIG. 13(B), the abnormality determination data processing unit PP1 as the data extraction unit, among the operation records of the track circuit TC, the falling data FD of the track circuit voltage, the rising data RD, and the rising data RD of the track circuit voltage. The abnormality determination data is extracted based on the peak value PK of the residual voltage from the fall to the rise. In the example of FIG. 13B, in the figure, the falling data FD on the left side, the rising data RD on the right side, and the peak value PK of the residual voltage between the falling data FD and the rising data RD are , A combination of data on the same train. Described more specifically below, first, the fall data FD is obtained until the train enters the detection section from outside the detection section of the track circuit TC and is electrically short-circuited and blocked by the wheel axle of the train. It is data obtained by measuring changes in the track circuit voltage for about 10 seconds before and after. The rising data RD is before and after the train existing in the detection section of the track circuit TC enters and goes out of the detection section until the electric short circuit at the wheel axle of the train disappears and the blocked state is released. It is data obtained by measuring the change in the track circuit voltage for about 10 seconds. The peak value PK of the residual voltage is data about the value of the residual voltage equal to or higher than the threshold value generated when the change of the track circuit voltage is measured from the fall to the rise, that is, while the train is in the track circuit TC. Is. Regarding these data measurements, similar to the case illustrated in FIG. 7(A) in the first embodiment, in order to continuously operate and catch a dynamic change, for example, the sampling time is set to a unit of 50 mm seconds, and the sequential orbit is performed. Measuring the circuit voltage. It should be noted that all of these data may be recorded together with the time information of the operation in the data processing unit 12 or the like. Here, of the above, for the falling data FD and the rising data RD, the most recent (latest) one-time data is extracted as a record relating to abnormality and normality, and is the target of normal/abnormality recording data to be transmitted to the data collecting device 20. Becomes On the other hand, regarding the peak value PK of the residual voltage, only the time point when the voltage exceeding the predetermined threshold value is detected is extracted and is the target of the abnormality determination data to be transmitted to the data collection device 20. Regarding the above judgment criteria, for example, with respect to each of the falling data FD and the rising data RD, a predetermined voltage value serving as a reference for whether the voltage is sufficiently lowered or raised is set as a threshold, and the threshold is used as a reference. To determine whether there is any abnormality. Alternatively, a standard may be set for the manner of change of the falling and rising. Regarding the peak value PK of the residual voltage, it can be considered to determine that it is abnormal when it exceeds a predetermined threshold value or when the time when the threshold value is exceeded continues for a certain time or more.

  Also in the present embodiment, from the operation records related to the track circuit, the normal abnormality record data, which is a record regarding the latest abnormality and the normality, and the abnormality determination data including the accumulated number of abnormalities are extracted by the data extraction unit. By transmitting the abnormality determination data from the communication terminal to the data collection device within a predetermined distance and having the data collection device acquire the data, it is possible to reduce the amount of data during communication and ensure the data required for the abnormality determination. It is possible to maintain the transfer of information, reduce the number of personnel for maintenance, and solve the labor shortage. Particularly, in the present embodiment, by extracting the abnormality determination data based on the fall data as the operation record, the rise data, and the peak value of the residual voltage from the fall to the rise, it is particularly important as the abnormality of the track circuit. It is possible to cause the data collection device to acquire important information and information that requires emergency.

[Third Embodiment]
An example of the equipment monitoring system according to the third embodiment or a railroad crossing device as equipment applicable to the equipment monitoring system will be described below with reference to FIG. 14.

  The railroad crossing device and the equipment monitoring system including the same according to the present embodiment are modifications of the equipment monitoring system exemplified in the first embodiment and the like, and are the same as the case of the first embodiment and the like, except for the details of the railroad crossing device. Therefore, the description of the entire facility monitoring system will be omitted, and only the level crossing device will be described.

  FIG. 14 is a conceptual plan view showing a configuration example of the railroad crossing device RC as the equipment EQ according to the present embodiment. In other words, it can be said that a detailed example of the railroad crossing device RC as the equipment EQ shown in FIG. 1 is shown. Although the field device 10 is drawn from the main body portion of the crossing device RC that constitutes the railroad crossing device RC in the drawing for the sake of clarity, the assembly mode of the field device 10 is not limited to this. Instead, various things are conceivable.

  As illustrated and as described above, the railroad crossing device RC according to the present embodiment communicates the normal/abnormal recording data and the abnormality determination data extracted by the data extracting unit 12b by various processes inside the railroad crossing device RC. It is transmitted from the communication unit 13 which is a terminal. Further, in the present embodiment, the railroad crossing device RC processes data regarding the relay operation in the pair of railroad crossing controllers (closed circuit type railroad crossing controllers) CC1 and CC2.

  First, an outline of a railroad crossing device RC of one configuration example will be described with reference to FIG. 14. As shown in the drawing, and as described above, the railroad crossing device RC is provided with the on-site device 10, and while the data collection device 20 mounted on the train TR is within a distance of 100 m. In, it is possible to communicate. The field device 10 is also connected to a pair of railroad crossing controllers CC1 and CC2 that form the railroad crossing device RC, and acquires data regarding relay operation in the pair of railroad crossing controllers CC1 and CC2 and collects data regarding the acquired data. Transmission to the device 20 is possible.

  The pair of railroad crossing controllers CC1 and CC2 are installed outside a predetermined distance from the railroad crossing, and the start point and the end point of the alarm are determined by train detection. In the illustrated example, the railroad crossing controller CC1 defines the starting point, and the railroad crossing controller CC2 defines the ending point. Therefore, the validity of the arrangement of the level crossing controllers CC1 and CC2 shown in the figure is very important, and it is necessary to calculate the control section lengths Ls and Le of the level crossing controllers CC1 and CC2. Therefore, in the present embodiment, in order to be able to calculate the control section lengths Ls and Le, in the field device 10 of the railroad crossing device RC, time data regarding the relay operation of the railroad crossing controller is extracted, and the time data is collected from the data collection device 20. I am sending. More specifically, as time data, first, the time when the train TR passes the starting point tip St of the railroad crossing controller CC1 is time Ts0, and the time when the train TR passes the starting point rear end Sr is time Ts1. Further, the time when the train TR passes the end point tip Et of the railroad crossing controller CC2 is time Te0, and the time when the train TR passes the end point rear end Er is time Te1. The information of these times Ts0, Ts1, Te0, Te1 can be grasped by detecting the relay operation when the train TR passes through the level crossing controllers CC1, CC2 on the side of the field device 10.

In the above description, the inter-axle distance of the train TR is further referred to as the inter-axle distance Lt, and the distance from the start point tip St to the end point tip Et is set to the distance L. Here, it is assumed that the inter-axle distance Lt and the distance L are known, and that the speed of the train TR while passing through the section of the pair of railroad crossing controllers CC1 and CC2 can be regarded as substantially constant. Let the average speed V in the section be the speed of the train TR. In this case, first
Average speed V=distance L/passing time (Te0-Ts0) (1)
Thus, the average distance V is calculated by substituting the known distance L and the detection result of the time in the field device 10 into the above equation (1). further,
Starting point control section length Ls=V×passing time (Ts1-Ts0)-axle distance Lt (2)
End point control section length Le=V×passing time (Te1-Te0)-axle distance Lt (3)
Therefore, by using the average speed V calculated from the above equation (1), the control section lengths Ls and Le can be calculated from the above equations (2) and (3). That is, the control section lengths Ls and Le can be calculated from the information of the times Ts0, Ts1, Te0, and Te1. Since a slight difference in communication time has a great influence on the calculation result of the control section length, for example, the values of the transit time (Te1-Te0) and the transit time (Ts1-Ts0) are set to the individual times Ts0, Ts1,. By using the difference as data, rather than calculating from Te0 and Te1, it is expected to obtain a more desirable result (calculation with high accuracy).

  Also in the present embodiment, from the operation records regarding the level crossing device, the normal abnormality record data that is the record regarding the latest abnormality and the normality, and the abnormality determination data including the accumulated number of abnormalities are extracted by the data extraction unit. By transmitting the abnormality determination data from the communication terminal to the data collection device within a predetermined distance and having the data collection device acquire the data, it is possible to reduce the amount of data during communication and ensure the data required for the abnormality determination. It is possible to maintain the transfer of information, reduce the number of personnel for maintenance, and solve the labor shortage. In particular, in the present embodiment, as operation records, time data relating to the relay operation in the level crossing controller is extracted, and the communication terminal transmits the time data to the data collecting device, thereby validating the position of the level crossing controller. It is possible to acquire data to judge sex.

  In the third embodiment, the data is transmitted from the field device 10 provided in the railroad crossing device CR, but the field device 10 may be independently provided in the railroad crossing controller to perform the transmission. Good.
