[0041]
【The invention's effect】
As described above, particularly in the invention of the present application, conventionally, a wiring construction plan has been manually listed as a cable to be newly laid, a cable to be disconnected, a cable to be removed, etc., based on a drawing such as a development connection diagram, and used as a construction drawing. However, with the wiring work planning means in the present invention, it is possible to automatically collect and list new laying / disconnecting / connecting / removing cables based on the data of the developed connection diagram. Since the data is transmitted to the site and used for construction, construction drawing creation time and shipping time are shortened. Examples of items that are automatically collected from the developed connection diagram include “Cable No.” “Circuit No. of Power / Control / Instrumentation” “Cable No.” “New Installation / Disconnection / Connection / Removal” “Existing Connections” Device name and device number "," new connection destination device name and device number "," new connection destination information ", and the like. Examples of items that are automatically collected from the connection diagram are “Cable type”, “Cable size and number of cores”, “Terminal block number of existing connection”, “Terminal block number of new connection destination”, “Source and destination of cable” Or the like.
[0042]
Traditionally, local power supply isolation work has been done by a power company, after the power company has created an isolation tag for each circuit and confirmed that the related circuit has been isolated. The cable related to the isolation circuit was extracted using the drawings and the like, and the work such as disconnection and removal of the cable was performed. The operation switch after the quarantine is hanged with a quarantine management tag and an operation prohibition display is displayed. There are various methods for confirming the power supply isolation, such as checking the isolation control tag, or contacting the power company with the notification document or drawing color classification indicating that it has been isolated from the power company. On the other hand, because the method was not unified, there was a risk that the power supply isolation staff would accidentally disconnect the cable of the circuit that was not isolated. In the power supply isolation means in this invention, in order to ensure isolation confirmation, when a power supply isolation part is specified on a drawing such as a developed connection diagram, devices such as switches corresponding to this are extracted and extracted based on the specification. Issue a power isolation tag with an identification code to a device (including a switch) (power isolation tag with identification code issuing means). At the time of isolation, a tag is placed on the operation switch to be isolated, the identification code is read, and the operation switch is operated. By reading the identification code, the record that the separation has been performed is accumulated in the data, and the construction worker can confirm the separation quickly by checking the record data. As the identification code, a reading device or a barcode for directly recognizing characters is used.
[0043]
Conventionally, on-site cable disconnection / removal / connection work is entered in the list created by extracting the connection / disconnection / connection work from the developed connection diagram etc. according to the progress of the construction. And process control. Regarding cable disconnection / removal / connection work, the work classification of the target cable was judged based on the list created based on the developed connection diagram, and the work was performed. There was a fear. In the wiring management means according to the present invention, in order to solve these problems, a connection identification code is pasted on the cable and the cable core, and a connection identification code for collating with the external cable is also pasted on the terminal block of the connected device. If the cable side and the device side match, the work instructions for installation / disconnection / connection / removal reflected from the developed connection diagram data are read and verified for each cable number. Do the work with the display. As a result, work mistakes can be prevented and stored as work results. In addition, it is linked with the local power supply isolation means, and if it is not isolated, it can be confirmed that work disconnection or removal work cannot be performed.
[0044]
Conventionally, the test schedule has been informed by the local test staff on the schedule. However, because the test schedule fluctuates from day to day, grasping when the schedule is changed may be delayed. With the test handover management means in the present invention, it becomes possible for the tester to quickly grasp the test schedule via the network by inputting the scheduled test schedule for the circuit and cable necessary for the field test. In addition, in conjunction with the wiring management means, it becomes possible for the test person to quickly grasp the progress of the person in charge of the local construction, which has been disconnected, removed and connected.
