While receiving the electronic report 44, the inspection requesting side 13 transmits to the inspection contracting side the electronic report 44 that has been viewed and electronically approved. In addition, the inspection requesting side 13 provides, for example, information on communication items that should be made known in advance when requesting the inspection contracting side 12 such as restriction of work contents and entry restriction, that is, the work schedule information 45 described above. It can be transmitted to the inspection contractor 12.

  Next, a plant instrument test method using the plant instrument test system 10 will be described.

  In the plant instrumentation test system 10, a loop constituted by a detector 21, an arithmetic / control device 22, and at least one of 23, 24 and an alarm display 25 as well as a test of a plant device alone. Tests such as automatic plant control and abnormality diagnosis (loop test) can also be performed by operating the work terminal 31 by the test operator.

  First, the work to be prepared in advance for the test (inspection) will be described. After receiving the inspection request from the inspection requesting side 13, the inspection contracting side 12 needs to obtain the approval of the inspection requesting side 13, which is the inspection requesting person, regarding the work contents of the inspection. That is, the inspection contractor 12 performs an input operation from the work terminal 51 to prepare the work procedure 41 and the electronic work slip 42 in advance, and transmits them to the data server 19 of the inspection requester 13 before performing the test. It is necessary to obtain the approval of the inspection requesting side 13 for conducting the test with the contents.

  Further, when performing the test, the plant equipment side 11 needs to connect a predetermined device for performing the test. Specifically, the work terminals 31, 32, 33, 34, and 35 are connected to the plant measurement control system 26 in a state as shown in FIG. 1, and the work terminals 31, 32, 33, 34, and 35 are required, respectively. Signal output and data acquisition are enabled, and the work terminal 31 stores a pre-operation manual 41 and an electronic work slip 42.

  After performing the above-described preparatory work, the worker operates the work terminal 31 to designate a test to be performed. More specifically, when reading the pre-operation manual 41 and the electronic work slip 42, it is possible to specify a test to be performed by specifying execution test identification information such as an ID of the pre-work guide 41 and the electronic work slip 42. it can. A desired test can be started by inputting a start request.

  Subsequently, a test (loop test) such as automatic plant control and abnormality diagnosis using the plant instrumentation test system 10 will be described. In the following description, it is assumed that the work terminal 32, the work terminal 33, the work terminal 34, and the work terminal 35 acquire data when performing the test.

  When a test start request is issued from the work terminal 31, a start command is transmitted to start work terminals (in this embodiment, work terminals 32, 33, 34, and 35) that are necessary for performing the test. When the instruction is received, the received work terminals 32, 33, 34, and 35 are activated, acquire the measurement values and states necessary for performing the test, and transmit the acquired measurement values and states to the work terminal 31. Is possible. The pre-operation manual 41 and the electronic work slip 42 are also transmitted to the activated work terminals 32, 33, 34, and 35.

  The work terminal 31 that has received the request to start the test sequentially displays guidance on the work to be performed by the worker on the work terminal 31 based on the description of the pre-work manual 41 and the electronic work slip 42. In addition, if a check operation such as predetermined device operation, safety confirmation or customer presence approval is required in the control room or central operation room which is an area other than the site where the work terminal 31 is operated at that time, the check work The contents are displayed on the work terminals 32, 33, 34, and 35.

  The work terminals 32, 33, 34, and 35 receive work start information from the work terminal 31 each time, and the work currently being performed is recorded in the pre-work instructions 41 and the electronic work slip 42. The work contents to be displayed on the display unit of the work terminals 32, 33, 34, and 35 based on the descriptions in the pre-work manual 41 and the electronic work slip 42. Can do.

  Information indicating the start and end of work (work progress information) is also transmitted from the work terminal 31 to the progress management terminal 38. The progress management terminal 38 displays the work progress status based on the work progress information received from the work terminal 31. The supervisor of the examination can grasp which work is currently being performed by checking the progress management terminal 38. Further, the progress management terminal 38 can access the work terminal 31 and the data server 17 and browse necessary information stored in the data server 17.

  In the control room or the central operation room, check contents displayed on the work terminals 32, 33, 34, and 35 are confirmed one by one by a worker in charge of the check work that requires a check by a person. . When the check work is completed, the worker inputs from the work terminals 32, 33, 34, and 35 that the check work has been completed. Then, the work terminals 32, 33, 34, and 35 that have received an input indicating that the check work has been completed transmit and notify the work terminal 31 that the check work has been completed.

  When a check work is required before the work starts, the work terminal 31 may start the work only after receiving an input indicating that all the check work has been completed or a notification that all the check work has been completed. Interlocked so that it can be configured. For example, when a predetermined confirmation work is required before providing the simulation signal to the detector 21, the work terminal 31 does not output the simulation signal unless it is accepted that the confirmation work has been completed. Further, the work terminal 31 is configured not to display the guidance for the subsequent work unless the work displaying the guidance is completed, so that the worker does not make a work mistake.

  The work terminal 31 observes the work described in the pre-operation manual 41 and the electronic work slip 42, that is, does not permit execution of work other than the work described in the pre-work guide 41 and the electronic work slip 42. In the plant instrumentation test system 10, the pre-operation manual 41 and the electronic work slip 42 have a meaning as a work permit.

  In the work terminal 31, when the pre-operation manual 41 and the electronic work form 42 do not exist (before storage), there is no work procedure to be observed and the execution of the test work is not permitted. In other words, it is configured that the test performed by the work recorded in the pre-operation manual 41 and the electronic work slip 42 is permitted only after the pre-operation manual 41 and the electronic work slip 42 are stored.

  The work terminal 31 determines whether or not the guidance work content has been completed based on the operation input from the worker, the notification of the completion of the work transmitted from the work terminals 32, 33, 34, and 35 and the acquired data. If the work terminal 31 tries to perform the work before the completion of the guided check work, or if it tries to perform another work before the guidance work is completed, the work terminal 31 determines that a procedure error has occurred. An alarm is issued to indicate that the work has not yet been completed (the procedure has been missed). An alarm issued from the work terminal 31 is made by at least one of sound output and display on the display unit (warning display).

  Subsequently, when the check operation is completed and the preparation for providing the simulation signal to the detector 21 is completed, the work terminal 31 receives an execution request from the worker, outputs the simulation signal, and synchronizes with the simulation signal. A command is issued to the work terminals 32, 33, 34, and 35 to acquire data. The work terminals 32, 33, 34, and 35 acquire data synchronized with the simulation signal output from the work terminal 31 through automatic measurement or the like, and transmit the acquired data to the work terminal 31.

  When at least one of the acquired data out of the work terminals 31, 32, 33, 34, and 35 deviates from a predetermined range and does not satisfy the test request (nonconforming), the working terminal 31 is incompatible. A warning is issued to the worker. It should be noted that for the work terminal that has acquired incompatible data among the work terminals 32, 33, 34, and 35, it is not essential to issue an alarm, and the alarm may not be issued.

  The work terminal 31 permits the same work to be redone if at least one of the data acquired from the work terminals 31, 32, 33, 34, and 35 is incompatible. 41 and electronic work slip 42 are not permitted unless they are revised. That is, in the plant instrumentation test system 10, the pre-operation manual 41 and the electronic work form 42 have a meaning as work permits.

  When an unscheduled situation occurs, for example, work not described in the pre-operation manual 41 and the electronic work form 42 is required, the work terminal 31 causes the work terminals 32, 33, Commands are issued to 34 and 35. Then, unless the work is permitted by the pre-revision manual 41 and the electronic work form 42 after considering the unscheduled situation, in other words, other work is performed unless a new work permit is issued. Can not do it. As a result, it is possible to prevent the test from being continued by the operator's discretion when an unscheduled event occurs, prevent further unexpected events, etc., and ensure the quality and safety of the test.

  As the work progresses according to the procedure of the pre-operation manual 41 and the electronic work slip 42, a data entry column provided in advance in the pre-operation manual 41 is filled in the process. When all the operations to be performed are completed, the pre-operation manual 41, that is, the data entry manual 43 in which data is entered in the column to be filled in by performing the test is completed. The work terminal 31 transmits the data entry procedure 43 to the inspection contractor 12 (data server 17) via the data transmitter / receiver 16 when the data entry procedure 43 is completed.

  When the inspection contractor 12 (data server 17) receives the data entry instructions 43, the data entry instructions 43 are stored in a predetermined recording means such as the data server 17 as original data of the test, and the plant instrumentation test system 10 The test using is terminated. The work terminal 31 makes an inquiry to the data server 17 accessible from the work terminal 31 whenever there is a user request, for example, work schedule information 45, inspection history DB 46, equipment drawing information 47, equipment specification information 48, etc. Information stored in the data server 17 can be referred to.

  After the test is completed, the inspection contractor 12 creates an electronic report 44 based on the description in the data entry procedure 43 and reports the prepared electronic report 44 to the inspection requester 13 in order to report the inspection contents to the inspection requester. Deliver.

  The electronic report 44 is created by the operator of the inspection contractor 12 operating the work terminal 51. For example, the operator can draft the electronic report 44 while confirming the data entry procedure 43. Further, if electronic data (not shown in FIG. 1) that is a template of the electronic report 44 is stored in the work terminal 51 or the data server 17 in advance and the data entry procedure 43 is designated, the designated data entry procedure is designated. 43. A program for creating the electronic report 44 by importing data necessary for the report into the template of the electronic report 44 from 43 is installed, and the electronic report 44 is created semi-automatically by executing the program. You can also.

  When the electronic report 44 is created on the inspection contracting side 12, the created electronic report 44 is transmitted from the inspection contracting side 12 to the inspection requesting side 13. For example, in the example shown in FIG. 1, an inspection request is sent from the data server 17 of the inspection contractor 12 connected so that electronic data can be exchanged between the inspection contractor 12 and the inspection requester 13 via the communication network 18. The electronic report 44 is transmitted to the data server 19 on the side 13.

  On the inspection requesting side 13, the received electronic report 44 is viewed and approved. The inspection and approval on the inspection requesting side 13 can be performed by, for example, confirming the contents and electronic approval using the data server 19. The electronic report 44 electronically approved by the inspection requesting side 13 is returned to the data server 17 of the inspection contracting side 12. The approved electronic report 44 returned to the inspection contractor 12 is stored as a quality record for a predetermined period under the responsibility of the inspection contractor 12.

  According to the plant instrument test system 10 and the test method using the plant instrument test system 10, the work terminal 31 is based on the descriptions in the pre-operation manual 41 and the electronic work form 42 in which the work terminal 31 is stored. The work to be performed can be sequentially displayed as guidance, and when there is work to be performed in the area where the other work terminals 32, 33, 34, 35 are arranged, the other work terminals 32, 33, 34, 35 are also displayed. It is configured so that no other work can be performed until the work terminal 31 confirms the input that the work confirmation has been made and the confirmation that the work has been confirmed. Can be prevented and can contribute to the improvement of work quality.

Therefore, even when an unscheduled situation occurs, it can be dealt with promptly and accurately, which can contribute to the improvement of work quality and the reduction of the burden on workers.

  On the other hand, the inspection requesting side 13 can receive the pre-operation manual 41, the electronic work slip 42, the data entry manual 43 and the electronic report 44 from the inspection contractor 12 as electronic information. Up to viewing and approval can be done electronically, and paperless can be achieved. In addition, work schedule information 45 including information to be communicated in advance when requesting a test to the inspection contractor 12 such as restriction of work contents, entry restriction, etc. can be transmitted to the inspection contractor 12. This can contribute to improving quality and reducing the burden on workers.

  In addition, although the test method using the plant instrument test system 10 and the plant instrument test system 10 described above describes the case where the test target is a loop test, the basic procedure and effect are The same applies to a single function test.

  The data transmitter / receiver 16, the work terminals 31 to 35, and the progress management terminal 38 are configured with computers. However, as long as the necessary functions are satisfied, the data transmission / reception device 16, the work terminals 31 to 35, and the progress management terminal 38 may be any type of computer. It doesn't matter. The computer includes a portable terminal such as a PDA (Personal Digital Assistant) in addition to a general-purpose computer. For example, the work terminal 31 has a certain level of function and is intended to save space in order to save space. In the central computer room indicator / recording meter 23, it is possible to select such as using a PDA having a function of further improving mobility and inputting a reading value such as an indicator.

  Note that the present invention is not limited to the above-described embodiment itself, and may be embodied by appropriately modifying the components without departing from the scope of the invention in the implementation stage. For example, the pre-operation manual 41 and the electronic work slip 42 are transmitted to the work terminal 31 via the communication network 15 and the data transmitting / receiving device 16, but the pre-operation manual 41 and the electronic work slip 42 are portable. Recording on a storage medium (for example, a well-known portable storage medium such as a magnetic disk, an optical disk, and a flash memory) and connecting the storage medium to the work terminal 31 on the plant equipment side 11, the pre-operation manual 41 and the electronic work The vote 42 may be read out.
