Further, when the state of the operation target stored in the operation storage unit 3b of the terminal device 3 and the identification information unique to the identification tag 1 provided in the operation target are received from the terminal device 3, this received information is received from the identification tag 1. It transmits by radio to the communication unit 1b.

  In the present embodiment, the communication between the tag writer side tag communication unit 2b of the tag reader / writer 2 and the communication unit 1b of the identification tag 1 is the other closest to the operation target provided with the identification tag 1 to be the communication target. It does not reach the communication unit 1 included in the identification tag 1 provided on the operation target. That is, in the monitoring panel of FIG. 1, the identification tag 1 is provided for each operation target such as each measurement value display 12, each pilot lamp 13, and each operation switch 14, but is a communication target among them. When the tag reader / writer 2 is brought close to an operation target provided with any one identification tag 1, for example, a certain pilot lamp 13, it does not reach the communication unit 1 of the identification tag 1 provided in the nearest pilot lamp 13. Communication between the communication unit 1b and the tag writer side tag communication unit 2b of the tag reader / writer 2 is not established.

A reception confirmation signal is transmitted to the terminal-side communication unit 3c of the terminal device 3 via. When the terminal device 3 receives the reception confirmation signal in the terminal side communication unit 3c, the terminal device 3 displays on the display unit 3a that the identification tag 1 has received the identification information unique to the tag stored in the EEROM 1f.

  Further, the tag reader / writer 2 has a built-in battery, and when receiving information is transmitted from the reader / writer side tag communication unit as described above, a driving power source for operating the identification tag 1 is used as a power supply unit of the identification tag 1. A power supply unit 2c that wirelessly supplies 1b (1b3) is provided. When the identification tag 1 is an RF-ID tag, the power supply unit 2c sends drive power for operating the identification tag 1 as electric energy by radio waves, and when the identification tag 1 is an IR-ID tag In this case, a driving power source for operating the identification tag 1 is transmitted as light energy by infrared rays. When the identification tag 1 is an IR-ID tag, the tag reader / writer 2 has an infrared light emitting / receiving element 1b2 and a light receiving / generating element 1b3 exposed at its tip as shown in FIG.

  In such a configuration, the operator's operation support by the operation support system of the present embodiment is performed as follows.

  That is, the worker first operates the input key of the terminal device 3 at the time of the work, specifies the operation procedure or the operation target or the state of the operation target for the target work, and displays it on the display unit 3a. Among the information stored in the operation storage unit 3b of the terminal device 3, the information specified by the operation of the input key is the terminal side reader / writer side terminal of the tag reader / writer 2 via the code 4 from the terminal side communication unit 3c of the terminal device. It is transmitted to the communication unit 2a. Then, the operator brings the tag reader / writer 2 close to the operation target displayed on the display unit 3a of the terminal device 3, and indicates the operation target with the tag reader / writer 2 as in the conventional pointing confirmation with the index finger. From the reader / writer side tag communication unit 2b to the tag side communication unit 1b (1b1, 1b2) of the identification tag 1 indicated by the tag reader / writer 2, the operation target in the order according to the operation procedure stored in the operation storage unit 3b Identification information unique to the provided identification tag 1, or identification information unique to the identification tag 1 provided in the operation target stored in the operation storage unit 3b, or a state of the operation target stored in the operation storage unit 3b and Identification information unique to the identification tag 1 provided for the operation target is transmitted wirelessly.

  When the identification tag 1 indicated by the tag reader / writer 2 receives identification information unique to the identification tag 1 provided in the operation target in the order according to the operation procedure stored in the operation storage unit 3b, the identification information is If the identification information unique to the tag stored in the EEROM 1f matches, the CPU 1e activates the tag display units 1c and 1h. Therefore, when the operator correctly brings the tag reader / writer 2 close to the operation target displayed on the display unit 3a of the terminal device 3 in the order according to the operation procedure stored in the operation storage unit 3b, the operation target is provided. When the tag display units 1c and 1h of the identification tag 1 are activated, and the operator accidentally brings the tag reader / writer 2 close, the tag display units 1c and 1h of the identification tag 1 provided for the operation target do not operate. . For this reason, the operator confirms the operation of the tag display portions 1c and 1h of the identification tag 1 using the tag reader / writer 2, and thereby operates each operation in the correct order according to the operation procedure stored in the operation storage portion 3b. Objects can be manipulated sequentially.

  When the identification tag 1 pointed to by the tag reader / writer 2 receives identification information unique to the identification tag 1 provided in the operation target stored in the operation storage unit 3b, the identification information is stored in the EEPROM 1f. If it matches the identification information unique to that tag, the CPU 1e activates the tag display portions 1c and 1h. Accordingly, when the operator correctly brings the tag reader / writer 2 close to the operation target displayed on the display unit 3a of the terminal device 3, the tag display units 1c and 1h of the identification tag 1 provided on the operation target operate. When the operator accidentally brings the tag reader / writer 2 close, the tag display portions 1c and 1h of the identification tag 1 provided on the operation target do not operate. Therefore, the operator can correctly specify the operation target stored in the operation storage unit 3b by confirming the operation of the tag display units 1c and 1h of the identification tag 1 using the tag reader / writer 2. .

  When the identification tag 1 pointed to by the tag reader / writer 2 receives the state of the operation target stored in the operation storage unit 3b and the identification information unique to the identification tag 1 provided in the operation target, the identification information If the ID matches the identification information unique to the tag stored in the EEROM 1f, the CPU 1e activates the tag display unit 1h to display the status of the received operation target. Accordingly, when the operator correctly brings the tag reader / writer 2 close to the operation target displayed on the display unit 3a of the terminal device 3, the tag display unit 1h of the identification tag 1 provided on the operation target is activated, and the operation target Although the status is displayed, when the operator accidentally brings the tag reader / writer 2 close, the tag display section 1h of the identification tag 1 provided on the operation target does not operate, and the operation target status is not displayed. For this reason, the operator correctly identifies the operation target stored in the operation storage unit 3b by confirming the operation of the tag display unit 1h of the identification tag 2 using the tag reader / writer 2, and the state of the operation target. It becomes possible to confirm.

  At this time, when the tag display unit is the LED 1c shown in FIG. 4, the identification tag 1 turns on the LED 1c when receiving identification information unique to the tag stored in the EEROM 1f. Therefore, the operator determines whether the operation target to which the tag reader / writer 2 is approached is an operation target in the correct order according to the operation procedure stored in the operation storage unit 3b, or stored in the operation storage unit 3b. It is possible to recognize whether or not it is a correct operation target to be identified, or whether or not it is an operation target whose state stored in the operation storage unit 3b is to be confirmed by turning on the LED 1c. For example, when the dedicated tool 21 for the valve 23 is specified in a plant or the like, the identification tag 1 shines, so that it can be confirmed quickly and is particularly effective during emergency work.

  In addition, when the tag display unit is the nonvolatile liquid crystal display 1h shown in FIG. 5, the identification tag 1 receives the identification information unique to the tag stored in the EEROM 1f, and the received information is transferred to the nonvolatile liquid crystal display 1h. To display. This display is rewritten only when the display content of the non-volatile liquid crystal display 1h needs to be switched to the new display content. For example, in the monitoring panel 11 shown in FIG. 1, when the operation switch 14 to be operated is switched from the third switch from the left to the fourth switch 4 from the left, and the operation switch 14 is to be turned on, the display unit of the terminal device 3 is displayed. When displayed on 3a, as shown in FIG. 5, "switch 4 ON" is displayed on the non-volatile liquid crystal display 1h. Therefore, the operator determines whether the operation target to which the tag reader / writer 2 is approached is an operation target in the correct order according to the operation procedure stored in the operation storage unit 3b, or stored in the operation storage unit 3b. The non-volatile liquid crystal display device 1h displays whether or not it is a correct operation target to be specified, or whether or not it is an operation target whose state stored in the operation storage unit 3b is to be confirmed and the state of the operation target. Can be recognized.

  Further, when the tag display unit is the LED 1c and the non-volatile liquid crystal display 1h shown in FIG. 6, the identification tag 1 turns on the LED 1c and receives the identification information specific to the tag stored in the EEROM 1f. Information is displayed on the non-volatile liquid crystal display 1h. This display is also rewritten only when the display content of the non-volatile liquid crystal display 1h so far needs to be switched to the new display content. For example, in the monitoring panel 11 shown in FIG. 1, if the measured value display 12 to be confirmed is the first one from the left and the display value is “1256”, the display unit of the terminal device 3 is to be operated. When the value is displayed on 3a, as shown in FIG. 6, the LED 1c provided on the first measured value display 12 from the left is turned on, and the display value “1256” is displayed on the non-volatile liquid crystal display 1h. Is displayed. Therefore, the operator determines whether the operation target to which the tag reader / writer 2 is approached is an operation target in the correct order according to the operation procedure stored in the operation storage unit 3b, or stored in the operation storage unit 3b. Whether or not it is a correct operation target to be specified, or whether or not it is an operation target to be checked in the state stored in the operation storage unit 3b, and the state of the operation target are indicated by the lighting of the LED 1c and the non-volatile liquid crystal display It can be recognized by the display of the device 1h.
