Description

  The present invention relates to management of facilities such as gas, power, and water.

  Utility companies (gas companies and power companies) outsource operations to construction companies for the management of gas, power, and water facilities (eg, buried gas pipes, buried power pipes, buried water pipes). After the execution of management / construction work, the construction company workers measure the location of the site where the management / construction work was performed, record it in a memo, etc., bring the memo back to the construction company's office, create a drawing, and In general, work diaries are compiled and submitted to the requester (utility company) as a completed book.

  As a conventional technique related to such facility management, there is a “distribution line diagram drawing device” described in Japanese Patent Laid-Open No. 8-314374.

  This “distribution line diagram creation device” automatically determines the position of the distribution facility on the actual coordinates obtained from GPS (Global Positioning System) and reflects it on the distribution line diagram, This is a simplified device, a GPS coordinate input means for inputting actual coordinates and equipment types measured by GPS, a graphic information definition storage means for defining equipment types and graphic information, and a distribution line for storing distribution line diagrams. The electric diagram data storage means and the input actual coordinates are converted into graphic coordinates, the graphic information is selected from the definition storage means based on the equipment type, and the graphic coordinates and graphic information are defined. The graphic information of the corresponding area of the distribution line map of the data storage means is read based on the graphic information of the data storage means, and the graphic information of the area is displayed under the graphic information of the defined graphic coordinates. Data processing means for updating and graphic information registration means for updating old graphic information in the data storage means using the graphic information of the updated graphic coordinates are provided.

JP-A-8-314374

  However, according to the “distribution line diagram drawing device” described in JP-A-8-314374, the position of each facility cannot be measured with high accuracy, and the description is made with a centimeter-class resolution such as piping diagram creation. There is a problem that it is not possible to create a diagram showing the exact location of each facility that is required. In addition, there is a problem that the excavation work performed with a centimeter resolution such as a buried object cannot be handled, which is a problem different from the “distribution line diagram drawing device”.

Positioning is performed (step S103). Since the RTK-GPS positioning system itself is an existing system, details thereof are omitted. After positioning the location of the positioning target facility, the RTK-GPS positioning processing unit 103 outputs information (latitude / longitude information) indicating the location of the positioning target facility to the completed drawing generation unit 104.

  Next, the completed drawing generation unit 104 generates an electronic map transmission request for requesting transmission of an electronic map corresponding to the location of the positioning target facility measured by the RTK-GPS positioning processing unit 103, and the wireless communication unit 110 An electronic map transmission request is transmitted to the construction company server 4, and the wireless communication unit 110 receives the electronic map as a response to the electronic map transmission request (step S104). The electronic map transmission request generated by the completed drawing generation unit 104 includes information (latitude / longitude information) indicating the location of the positioning target facility, and the construction company server 4 includes the positioning target included in the electronic map transmission request. A corresponding electronic map is transmitted based on information indicating the location of the facility (latitude / longitude information).

  Next, the completed drawing generation unit 104 adds information (latitude / longitude information) indicating the location of the positioning target facility to the electronic map received in step S104, and the location of the positioning target facility on the electronic map. The position is superimposed and displayed as a completed drawing (step S105). In addition, when the positioning target facility is a facility having a certain length, such as a buried gas pipe, a plurality of positioning points are connected and the pipeline is displayed on the electronic map. Here, the completion drawing generated by the completion drawing generation unit 104 may be displayed on the display unit 109 to prompt the positioning operator 1 to confirm.

  Next, the user input unit 105 inputs work diary information from the positioning worker 1 (step S106). The work diary information is, for example, the positioning date and time, the name of the positioning operator, the type of the target facility for positioning (whether the target facility is a buried gas pipe or a buried power pipe, etc.), the material and dimensions of the positioning target facility This is information (related information) related to the positioning of the positioning target facility. Further, at this time, the photographing unit 106 may photograph the positioning site, and the captured image of the positioning site may be used as work diary information.

  Next, the work diary generation unit 107 edits the work diary information and generates a work diary having a data format determined by the utility company (step S107). At this time, the work diary generated by the work diary generation unit 107 may be displayed on the display unit 109 to prompt the positioning worker 1 to confirm.

  Next, the drawing / diary integration unit 108 integrates the completed drawing generated by the completed drawing generation unit 104 and the work diary generated by the work diary generation unit 107 into a completed book (step S108). This completed book is data in a format that can be electronically delivered to the utility company server 5 as it is.
