Description

  The present invention relates to a method and apparatus for collecting equipment inspection data.

  In general, when a facility deteriorates or malfunctions, there is a possibility of causing various obstacles to the operation of the facility. Therefore, it is necessary to perform an inspection in order to detect the function degradation or failure. For example, the Ministry of Land, Infrastructure, Transport and Tourism stipulates that railway electrical switchboards must be inspected at least once a year. This implementation obligation is imposed regardless of the presence or absence of the monitor device, and it is defined that the inspection is conducted at the installation location of the equipment (Non-Patent Documents 1 and 2).

  The electric switch is equipped with a monitor device having a function of transmitting data measured by various sensors to a station device that is often installed in a station unit using a wired or wireless communication line. Inspection data is transmitted at every switching operation and at regular intervals (Non-Patent Documents 3, 4, and 5).

Ministerial Ordinance Establishing Technical Standards for Railways Article 90, Paragraph 2 Notification of Ministry of Land, Infrastructure, Transport and Tourism No. 1786 facility and periodic inspection of vehicles Power supply, electric lines, protectors, centralized monitoring system Japan Railway Electrical Engineering Association July 27, 2007 p111 Kyosan Circular Vol.41, No.4, pp3-13, 1990 Railway Technical Research Institute Bulletin No.A-86-102, 1986 Getting start with iBeacon version 1.0, Apple

  Since the above monitoring device is mainly intended to constantly monitor the state of equipment, a function for transmitting inspection data from the inside of the electric switch to a maintenance area, a command office, etc. is indispensable. In the case of wired communication, it is necessary to install a new cable to each facility on the premises, to re-lay or use an empty line, and to transmit information from each terminal to the higher-level system and a device that aggregates information for each terminal. Communication network and transmission capacity are required. Therefore, in order to introduce a constantly monitoring monitor device, in addition to a terminal installed for each facility, an upstream device such as a transmission system or a station device is required. Often these are expensive and require large capital investments at once. For this reason, there are not a few electrical switchboards and other railway facilities that have undergone a patrol inspection without introducing a monitoring device.

  In the inspection of electrical switchboards, as a rule, inspections involving measurement of operating current and voltage, adhesion, lock error, switching time, current and voltage during disturbance, foreign object detection status, An appearance inspection is performed to confirm the appearance of the attached device. Moreover, these inspection results are recorded in a field note (field note) at the site and further stored as an inspection ledger.

  A problem related to the conventional inspection of equipment is that there are many equipment and factors necessary for inspection. For example, in order to carry out the inspection contents exemplified above, in the example of the inspection of an electric switch, a voltmeter, an ammeter, an adhesion meter, a stopwatch, an inspection iron piece corresponding to a foreign object (of an operating tool) A foreign object intentionally interposed between them and an adjustment tool are required. In addition, since a minimum of two workers are required to conduct the patrol inspection, a total of a total of three people is required, including one train guard.

  In addition, the information recorded by the conventional inspection method is an information amount of about four significant digits at the maximum, and is not a time series waveform but an instantaneous value entered on the inspection sheet or an average value of the entire operation. is there. In addition, collection of detection information is performed in the vicinity of the inspection target.

  In the conventional inspection method, the inspector brings inspection equipment to each equipment, attaches it to the equipment, measures the operating current and voltage, confirms the start and end of the operation, measures the operating time, calculates the average value, etc. As a result, the burden on the inspector is large, and the inspection results vary depending on the skill of the inspector, and the inspection time is prolonged.

  Next, embodiments of the present invention will be described with reference to the drawings.

  The facility inspection data collection method according to the embodiment of the present invention has no trouble in the acquisition and collection of the detection information with a frequency of about 1 to 12 times per year, in other words, the facility that is mainly subject to the inspection. Applies to equipment. However, it can also be applied to equipment that is not subject to patrol inspection.

  The first embodiment of the facility inspection data collection method according to the present invention is a basic embodiment. As shown in FIG. 1, sensors a1, a2,... For detecting the operation or state of the facility A. , and an equipment terminal B for obtaining the inspection data output by the sensors a1, a2,... an is electrically connected to the equipment A, and the inspector records a recording device during the cyclic inspection of the equipment A. C (hereinafter referred to as a recording box) and collecting and recording inspection data from the equipment terminal B to the recording box C via a communication line formed between the recording box C and the equipment terminal B is there.

  Equipment A may include, for example, electrical switchboards, traffic lights and other signal security equipment, level crossing safety equipment such as level crossing breakers and level crossing alarms, road equipment such as road traffic signals, and other various equipment. . There may be only one sensor a1, a2,... An depending on the type of equipment, or there may be two or more sensors. Further, the sensors a1, a2,... An may be either newly installed in the facility A or when existing ones are used.

  The equipment terminal B obtains output data from the sensors a1, a2,... An, analyzes the data, creates a message, and transmits the message to the recording box C. The timing at which the equipment terminal B obtains the inspection data from the equipment A differs depending on the type of equipment, but it is not always necessary to obtain it. When the inspector arrives at the facility during the patrol inspection, the inspection data from each of the sensors a1, a2,... An may be acquired within a predetermined time from when the start switch provided in the facility terminal B is operated. Further, the facility terminal B may be provided with an approach detection means for detecting that the recording box C has approached within a certain distance, and the inspection data may be acquired within a certain time from when the approach detection means is activated. Good.

Then, the equipment terminal B analyzes the data acquired within a predetermined time from the time when the start switch is operated or the approach detection means is activated, creates a message based on the analysis result, and records the message in the record box To C. In a preferred embodiment, transmission is performed by one-way communication. When transmission from the equipment terminal B is performed by one-way communication, an effect such as an inability to attack the field device from the outside can be obtained.

  The recording box C receives the electronic message transmitted from the equipment terminal B and stores it sequentially. After the inspection at one facility or after the inspection at a plurality of facilities is completed, the recording box C is moved to a predetermined management facility and wired or wirelessly connected to a higher-level management device D provided in the management facility. The message stored in the record box C is taken up by the management device D via the transmission line. In the management apparatus D, the message is displayed, and the staff determines whether the function of the facility A has deteriorated or malfunctions.

  In the first embodiment, the equipment A is installed in the equipment A or the equipment terminals B that acquire and analyze the output data of the existing sensors a1, a2,. Since the message sent from the equipment terminal B is received and recorded by the record box C brought during the cyclic inspection, the inspection effort in the cyclic inspection is reduced, the inspection data handling method is leveled, and the upper system No transmission device is required. Therefore, the introduction cost is much lower than when a constant monitoring type monitoring device is introduced. Furthermore, when transmitting from the equipment terminal B to the recording box C by one-way communication, it is possible to obtain an effect that an attack or malfunction of the equipment terminal B due to external radio waves can be avoided.

  FIG. 2 shows a second embodiment of the equipment inspection data collection method according to the present invention. In the second embodiment, a backup function is added when a failure occurs while the first embodiment of FIG. 1 is being implemented. That is, in the second embodiment, a recording unit b1 for recording inspection data acquired from each sensor a1, a2,... An of the facility A and an output unit b2 for outputting the recorded contents are added to the facility terminal B. . Then, the acquired inspection data is recorded continuously or at regular intervals in the recording unit b1, and when a failure occurs, the data collection device E is brought to the site and electrically connected to the equipment terminal B. Alternatively, the recording contents (past data) of the recording unit b1 are wirelessly taken up by the data collection device E. The data collection device E is taken home and outputs the sucked information to the management device D.

  The recording unit b1 records the inspection data acquired by the equipment terminal B sequentially in a FIFO (First In First Out) method, or the equipment between the previous cyclic inspection and the next cyclic inspection. Inspection data acquired by the terminal B is recorded. When the data collection device E is connected and all of the recorded content of the recording unit b1 is output, the recorded content of the recording unit b1 is erased to prepare for recording of the next acquired inspection data.

  FIG. 3 shows a third embodiment of the facility inspection data collection method according to the present invention. In the second embodiment, the data collection device E is connected to the equipment terminal B when a failure occurs, and the past data in the recording unit b1 is sucked into the data collection device E. On the other hand, the third embodiment The monitor device F is always connected to the recording unit b1 and the output unit b2 of the terminal B, and inspection data is transmitted from the monitor device F to the management device D. This is an embodiment in the case where the first embodiment is implemented in the facility A, which is the object of the cyclic inspection, in which the monitoring device is not introduced, and then developed into a constant monitoring mode.

  The third embodiment is different from the conventional continuous monitoring type monitor device in that the output data from each sensor of the facility is the same as the recording unit b1 and the output unit b2 in the equipment terminal B. In other words, the inspection data of each sensor of the facility A is directly transmitted to the monitor device without going through the process.

  Next, an inspection data collection apparatus that implements the facility inspection data collection method will be described. Hereinafter, as shown in FIG. 4, an embodiment of the present invention will be described by taking as an example the case where the facility A1 is an electric switch. The inspection data collection device is composed of an equipment terminal B and a recording box C attached to the electric switch A1. As shown in FIG. 5, the equipment terminal B has an I / O interface 1 for taking in detection outputs from the sensors a1, a2,... An of the equipment A, a processing device 2 constituted by a CPU, and processing results. And a transmitter 3 for transmitting to the recording box C.

  The I / O interface 1 is connected to detectors (sensors) of the electric switch A1, such as a voltage sensor 11, a current sensor 12, a displacement sensor 13, a strain amplifier 14, and the like, and outputs from these sensors. An analog signal or a digital signal is input to the data collection unit 21 described later via the I / O interface 1.

  The processing device 2 includes a data collection unit 21, a data analysis unit 22, a message creation unit 23, and a message transmission unit 24 each configured by software. That is, the equipment terminal B has a data collection function, a data analysis function, a message creation function, and a message transmission function.

  The data analysis unit 22 analyzes the data collected by the data collection unit 21 according to a specific rule, and converts the data into a form to be entered in the ledger. More specifically, in the case of the electric switch (A), the output of the current sensor 12 is used to detect the start and end of the conversion operation, and the maximum value and average value of each sensor output within that period. Is calculated and created in a format that can be entered in the ledger. This is the same as the operation of the monitor device of the existing electric switch.

  The message creation unit 23 creates a message to be transmitted based on the data created by the data analysis unit 12. For example, a message as illustrated in the table of FIG. 6 is created. This message includes an ID (da) unique to the device, an information type (db), and a measurement value (dc). As an example, the device-specific ID (da) is 16 bytes, the information type (db) is 2 bytes, and the measurement value (dc) is 2 bytes. FIG. 6 shows a message (AAAA... FFFO, 0002, 033E) when the information type of the S station No. 21 switching machine is the average current and the measured value is 8.30 A, and the S station No. 21 switching machine. A message (AAAA... FFFO, 0003, 01AE) when the information type is the conversion time and the measured value is 4.30 s is illustrated.

  The message transmission unit 24 transmits the message created by the message creation unit 23. In a preferred embodiment, the data is transmitted by one-way communication using a PAN (Personal Area Network). Since it is a one-way communication, it does not have a function of checking that the receiving side has received it reliably. Therefore, in order to increase the reception probability on the receiving side as much as possible, the message transmission unit 24 is configured to automatically transmit a message having the same content three times in succession. That is, as shown in FIG. 7, the amount of information that can be transmitted at one time is reduced, and one content is included in one message, and the next message is transmitted after three messages are continuously transmitted. FIG. 7 shows an example in which each message d1, d2, d3,... Is sent three times every 100 ms. In the preferred embodiment, the end message de is sent three times, and thereafter the waiting message dw is sent at a long interval until some action occurs.

  FIG. 8 shows an example of data analysis of the data analysis unit 22. In the vertical axis of FIG. 8, the operating current, operating voltage, lock-claw displacement L (stereo position lock), lock-clamp displacement R (inverted lock), NK (display localization), RK (display) The abscissa represents the transition time from orientation to orientation (N → R) and the transition time from orientation to orientation (R → N). It should be noted that the operating current was 13.6 A at the time of rushing and an average value of 7.6 A in (N → R), and 13.6 A and an average value of 7.5 A at the time of rushing in (R → N). The operating voltage was 98.6 V on average for (N → R) and 98.2 V on average for (R → N).

  From FIG. 8, as shown in FIG. 9, (a) the direction of the lock is obtained by using the lock displacement and the circuit controller contact, and (b) the start of the conversion operation using the change in current, KR, etc. (C) The inrush current and the other current are separated by using the change in current and the displacement of the lock mechanism. The message creation unit 23 creates a message as shown on the lower side of FIG. 9 based on these data. The 8-digit numerical value on the left side of each message is the ID of each sensor, and the data on the right side is the information type and the measured value. The message transmission unit 24 activates the transmitter 3 to transmit the message.

  When the start switch (not shown) provided in the equipment terminal B is operated, or when the known proximity sensor provided in the equipment terminal B detects that the recording box C is approaching within a predetermined distance, the processing device 2 The above-described inspection data acquisition, analysis, message creation, and message transmission are performed. The processing time can be arbitrarily set by the inspector according to the current state of the equipment.

  In recent years, with the progress of wireless communication technology, wireless communication systems with low power consumption, a small range, and a small amount of information have been put into practical use. For example, Non-Patent Document 6 uses a technique in which information of a total of 18 bytes reaching a range of 20 cm or less is unidirectionally communicated from a device at intervals of several hundred ms. As the transmitter 3 of the equipment terminal B, a transmitter capable of short-range wireless communication similar to this is used. However, the reach of radio waves can be set as appropriate as long as it does not interfere with communication with other nearby equipment terminals.

Next, the operation of the processing apparatus 2 will be described using the flowchart of FIG.
The flow on the left side of FIG. 10 shows loop processing in the standby state of the facility terminal B. The standby state is started at the loop standby in step S1, and the input from each of the sensors a1, a2,. In the next step S3, the input value is stored at regular intervals by the FIFO method, and the old value is discarded. In step S4, it is determined whether or not the value of the specific channel is greater than a threshold, for example, whether or not the operating current has exceeded 1 ampere, for example. If this determination is negative (No), it is determined that there is no change in the sensor output state, and a standby telegram indicating that there is no change in state is output in step S5. Based on this, a loop end process is performed in step S6, and the process returns to step S1.

  When the determination in step S4 is affirmative (Yes), the process proceeds to step S7, and the analog input from any sensor is recorded for a certain time, for example, for 10 to 15 seconds.

  FIG. 11 is a diagram illustrating an example of the history of recording in step S7 from the determination in step S4. This example is a case of recording output data of a current sensor. The range of A in the figure is data stored in the standby loop, and when the data exceeds the threshold value 1A, the recording in step S7 is started.

  In step S8, the recorded data is combined with standby data. Subsequently, in step S9, the combined data is analyzed, and in step S10, the above-described message is created based on the analysis result. Steps S <b> 11 to S <b> 15 are a loop that performs processing of transmitting the created message continuously, for example, three times. In step S11, i = messages 1 to n indicates the number of messages, and j = 1 to 3 in step S12 indicates that the number of transmissions is three. In steps S11 to S15, the messages d1 to df illustrated in FIG. 7 are transmitted three times every 100 ms, for example, and then the waiting message dw is finally transmitted, and the process proceeds to step S1.

  Next, the recording box C will be described. As illustrated in FIG. 12, the recording box C includes a communication unit 31, a first storage unit 32, a terminal selection unit 33, a second storage unit 34, and a data transmission unit or data output unit 35. That is, the record box C has a communication function with the equipment terminal B, a storage function for sequentially storing the received contents, a selection function for the nearby terminal (B), and a data communication function. Each part will be described below.

  The communication unit 31 receives a message transmitted from the communication device 3 of the equipment terminal B. The first storage unit 32 sequentially stores messages received from the communication device 3 of the equipment terminal B. For example, in a railway facility, a plurality of facilities may be installed at a relatively close distance. In such a case, a message transmitted from the plurality of equipment terminals may be received in the recording box C. The terminal selection unit 32 is provided for preventing interference in such a case. The terminal selection unit 32 selects a message from the equipment terminal that is determined to be the closest from the strength of the radio wave received from the communication device 3 of the equipment terminal B. For example, when iBeacon (registered trademark) is used for the message communication unit 24 of the equipment terminal B, the equipment terminal B can perform distance measurement in four stages of “none”, “far”, “close”, and “immediately”. And when the signal is received from a plurality of equipment terminals, for example, the signal received from the equipment terminal determined to be “immediately” is selected. The 2nd memory | storage part 34 memorize | stores the selected message | telegram inside. If a message having the same content as the previously received message is received, the message received later is discarded.

  As a preferred embodiment of the equipment terminal B, when the end message de is sent, the reception end notification means 36 is added to the recording box C. When receiving the end message de, the reception end notification means 36 informs the inspector that the data reception has ended by turning on a lamp or sounding an alarm. The inspector takes the record box C back to the maintenance area or the like based on the data reception end notification.

  The data transmission unit or data output unit 35 receives the detection information stored in the second storage unit 34 when the record box C brought back to the command office is connected to the management device D such as the maintenance area so that information can be transmitted. Transmit or output to the management apparatus D.

  Depending on the equipment, in addition to the normal operation check, the operation may be intentionally interrupted to check the state at that time. For example, in an electric switch, a foreign object (the above-mentioned inspection iron piece) is sandwiched between the basic rail and the tongrel and the electric switch is forcibly driven to obtain and monitor the output of each sensor. To be done. In such a case, a test switch is provided in the recording box C, and means for indicating that the data acquired after operating the test switch is data at the time of disturbance different from the data at the time of normal inspection is added. .

  As another embodiment, instead of the recording box C, an application having the same function as that of the recording box C is mounted on a mobile terminal, for example, a smartphone, and the mobile terminal is brought to the inspection of the facility. Inspection data can also be collected.

  Although the above has described the case where the facility is an electric switch, FIG. 13 shows an embodiment where the facility A2 is a railway signal facility. In this example, the equipment terminal B1 is connected to the instrument box Ab of the traffic light Aa, the recording box C brought by the inspector approaches the equipment terminal B1, and the start switch SW of the equipment terminal is pressed or the approach is detected. At this time, a message in which the items illustrated in FIG. 14 are encoded is transmitted from the equipment terminal B1 to the recording box C.

  Other items detected by the sensor in the signal equipment include presence / absence of disconnection and voltage, and in the track circuit, there are voltage and phase difference between normal time and short circuit.

  FIG. 15 shows an embodiment where the facility A3 is a railroad crossing safety device. In this example, the equipment terminal B2 is connected to a railroad crossing device box Ac that gives a control signal to a railroad crossing breaker or an alarm device, the recording box C brought by the inspector approaches the equipment terminal B2, and the start switch SW of the equipment terminal is turned on. When pressed or when an approach is detected, a message in which the items illustrated in FIG. 16 are encoded is transmitted from the equipment terminal B2 to the recording box C.

  The items detected by the sensors in the level crossing safety device include the voltage of the rectifier and main relay of the above level crossing equipment box, and the voltage, current value, and operating time (when rising, falling and disturbing) of the level crossing breaker. In addition, there are voltage and control section length in the crossing controller.
