  Moreover, according to the other invention of this invention, in addition to the said effect, input mistakes, such as inspection operation content, can be avoided.

  Hereinafter, an inspection operation guidance system of the present invention will be described based on illustrated embodiments.

  FIG. 1 is a block diagram of an inspection operation guidance system according to an embodiment of the present invention. First, the first feature of this embodiment will be described. As shown in the figure, the operation procedure guide means 101, which is a portable operation procedure guide terminal, is associated with device names, inspection operation procedures, device identification information, and operation details of a plurality of devices 104 to be inspected. An inspection operation schedule as shown in FIG. 2 is stored. Further, the operation procedure guide means 101 of this embodiment is provided with a terminal wireless communication function that outputs the call signal 201 with the device identification information of the device 104 to be inspected.

  Each device 104 is provided with a device RFID 102 as device wireless communication means. As the device RFID 102, an RFID that is a well-known wireless identification device can be used, and a positive RFID or a passive RFID can be applied. In general, an RFID includes a wireless communication unit, a memory that stores information such as identification information, a microcomputer that controls the wireless communication unit and the memory, and transmits information such as identification information via the wireless communication unit. And an antenna for receiving a reading request from the outside.

  Each device 104 is provided with an explicit means 103 that indicates the position of the device 104 in correspondence with each device 104. As the explicit means 103, any one of a light emitting means, a sound generating means, a vibration generating means, and an odor generating means operated in accordance with an input explicit command 202, or a combination thereof can be applied. In the case of the light emitting means, the position of the device 104 can be confirmed very easily. The operation device 104, the device RFID 102, and the specifying means 103 are not necessarily integrated. Alternatively, the device RFID 102 and the explicit means 103 can be integrated.

  With this configuration, according to the first feature of the present embodiment, as shown in FIG. 3, the operator 001 instructs the operation procedure guide means 101 to inspect the next inspection target device. When input (S1), the operation procedure guide means 101 selects the next inspection operation target device 104 in accordance with the inspection operation schedule of FIG. 2, attaches the device identification information, and transmits a call signal 201 (S2). When the device RFID 102 receives the call signal 201, the device RFID 102 determines whether or not the device identification information attached to the call signal 201 is the device 104 corresponding to the device RFID 102. An explicit command 202 is output to the means 103. Upon receiving this explicit command 202, the explicit means 103 specifies the position of the device 104 selected by the operation procedure guide means 101 by, for example, light emission. As a result, the operator 001 can find the device 104 that is the next inspection operation target easily and without error by searching for the device 104 on which the explicit means 103 is operating in the field. In particular, since it is not necessary to read and confirm identification information such as the identification number and code of the device 104, it is possible to avoid erroneous operations such as inspecting other devices by mistake. The efficiency of inspection operation work can be improved.

  Next, a second feature of the present embodiment will be described with reference to FIG. The device RFID 102 is formed so that the device identification information of the corresponding device 104 can be transmitted. In addition, the device 104 outputs the operation information 301 of the contents inspected by the operator 001 to the device information reading unit 105, the operator information reading request unit 107, the device identification unit 106, and the operator identification unit 109. ing. In particular, the signal transmission path of the operation information 301 is a device information reading means 105, an operator information reading request means 107, an equipment identification means 106, and an operator by connecting a plurality of devices 104 by so-called crossover wiring or a single wireless transmission path. By applying a method of connecting to the identification unit 109, the signal transmission path can be simplified. In this case, the device 104 needs to have a function of permitting communication of the device information read request signal 203 and / or communication of the device identification information 204 only for a certain period of time when the device 104 is operated. This function can be realized by changing the direction of the antenna of the device RFID 102, opening / closing the reception and transmission circuits, or passing / blocking communication electromagnetic waves.

  The operator 001 wears or carries an operator RFID 108 capable of transmitting operator identification information. The device information reading request unit 105 and the operator information reading request unit 107 transmit a device identification information reading request signal 203 and an operator identification information reading request signal 205 when the operation information 301 output from the device 104 is input. It is like that. In response to the read request signals 203 and 205, the device RFID 102 and the operator RFID 108 transmit device identification information 204 and operator identification information 206, respectively. Here, an interference avoidance function is provided to prevent other operator RFIDs from receiving the operator information read request signal 205. That is, it is necessary to provide a function that prevents the operator information reading request signal 205 from being received by another operator's RFID. This function often limits the strength of the operator information read request signal 205 so that other operator RFIDs cannot be received or the operator 104 because the RFID of the device 104 and other operators are often separated. This can be realized by limiting the direction in which the information reading request signal 205 is transmitted.

  The operation information 301 output from the device 104 is also input to the device identification unit 106 and the operator identification unit 109. On the other hand, the device identification unit 106 and the operator identification unit 109 receive the device identification information 204 and the operator identification information 206, respectively, identify the device 104, identify the operator 001, and include the device identification information 204. Information 302 and operator information 303 are output to the operation recording means 110. Further, the operation recording unit 110 is configured to transfer operation record information 304 in which input device information 302 and operator information 303 are associated with each other to the operation record database 111. The operation record database 111 has a function of receiving operation record information 304 and managing operation records. The device information reading request unit 105 and the device identification unit 106 are not necessarily integrated.

  With this configuration, according to the second feature of the present embodiment, when the operator 001 operates the device 104 specified by the specifying means 103 as shown in FIG. 301 is transmitted (S4). When the device information read request unit 105 receives this operation information 301, a device information read request signal 203 is transmitted (S5). The device RFID 102 that has received the device information read request signal 203 transmits device identification information 204 (S6). The device identification information 204 is received by the device identification means 106, the device 104 is identified, the device identification information 204 is added to the operation information 301, the device information 302 is transmitted to the operation recording means 110, and transferred to the operation record database 111. (S7).

  On the other hand, as shown in FIG. 4, the operator information read request unit 107 also receives the operation information 301 and transmits an operator information read request signal 205 (S11). The operator RFID 108 receives the operator information read request signal 205 and transmits the operator identification information 206 (S12). The operator identifying unit 109 receives the operator identification information 206, identifies the operator 001, and transmits the operator information 303 to the operation recording unit 110. The operation recording unit 110 includes the operator information 303 and the device described above. The operation record information 304 associated with the information 302 is created, transferred to the operation record database 111 and stored (S13).

  As described above, according to the second feature of the present invention, at the timing when the device 104 is operated, the device 104 and the operator 001 who operated the device 104 are simultaneously identified and treated as a pair of data, and the operation record information 304 is recorded. Is recorded in the operation record database 111, so that a recording mistake when inputting the operation record information 304 and a transcription mistake when transferring the operation record information 304 to the operation record database 111 can be prevented.

  Note that the time required for reading RFID information is about several tens of milliseconds, and the time from the operation of the device 104 to the transmission of the operation record information 304 can be realized in a short time.

  As described above, according to the second feature of the present embodiment, the contents inspected by the operator 001 are output as the operation information 301 from each device, and are associated with the device and the operator via the identification unit. Since it is directly recorded in the operation record database 111 via the operation recording means 110, input mistakes such as inspection operation contents can be avoided.

  As described above, according to the present embodiment, the RFID is applied to the identification of each device and each operator, the RFID of the device to be operated is called to clearly indicate the position of the device, and at the timing when the device is operated, Since the operation device information and the operator information are instantly acquired and identified, and the operation details are automatically recorded, the time for confirming the device can be shortened, and erroneous operations such as device mistakes can be prevented. In addition, it is possible to prevent erroneous operations and automatically record operation details in inspection operations of a large number of devices with a small system configuration.

  In the above embodiment, the call signal for the next device is output from the operation procedure guide unit 101 according to the inspection operation schedule. However, the present invention is not limited to this, and an input unit is provided in the operation procedure guide unit 101 so that the operator can arbitrarily The selected device may be designated.

  In the present embodiment, the device 104 has a function of permitting communication of the device RFID 102 only when operated. As a means for realizing this function, the above-described method can be applied. As a means for detecting that the device 104 has been operated, for example, a strain sensor or a switch that is displaced in conjunction with the operation of the device 104 is provided. The communication function of the device RFID 102 can be validated in conjunction with the detection means.

  Further, since the operator RFID 108 cannot be linked to the device 104 like the device RFID 102, the operator information read request signal 205 cannot be set to be receivable when the device 104 is operated. On the other hand, if the reception is always possible, other operator RFIDs nearby receive the operator information read request signal 205, and operator identification information different from the correct operator is transmitted, and the operator identification means 109 May be misidentified.

  Therefore, it is necessary to prevent other operator RFIDs from receiving the operator information read request signal 205 for the correct operator. Such an interference avoidance function includes the methods described above, but instead of them, an interference avoidance function described below can be provided. For example, the operator RFID 108 is worn on a part where the movement of the operator 001 such as a finger, a wrist, an elbow, and a shoulder can be detected, and the operator RFID 108 is provided with a strain sensor or the like to detect the movement of the operator 001, and the detection The communication function of the operator RFID 108 can be validated by the signal. Further, the operator 001 may perform an operation so as to enable the communication function of the operator RFID 108 at the time of operation. Furthermore, the communication function of the operator RFID 108 may be enabled by using a signal for enabling the communication function of the device RFID 102 or the explicit command 202 transmitted from the device RFID 102 as a radio signal. By doing in this way, the one-to-one relationship between the operator and the device can be further ensured, and the reliability of the inspection operation is improved.
