With the rapid development of my country’s communications industry, relevant communications departments have set up more and more unattended communications base stations. The normal operation of the communication network mainly depends on the stability and reliability of the power and environment of each base station. Because the base station has a wide range of settings, and each base station is not equipped with a dedicated person on duty, it is easy to understand and eliminate the faults that occur on the base station in time. Cause the failure of the local area communication network. At present, the inspection of unmanned base stations is the main manual inspection method adopted by China Mobile’s Mianyang branch. However, with the progress and development of society, the requirements of its management work are becoming more and more standardized and scientific. All units have higher and higher requirements for the responsibility of regular maintenance and inspection personnel. Eliminating hidden dangers in time and preventing them before they happen is the hope of every business leader and manager. The information point inspection management system is an inspection system that uses the latest technology to closely combine information collection technology with computer technology and adapts to various inspection situations. The system has greatly improved the standardization and scientific level of various inspections, eliminated the phenomenon that the inspectors could not be scientifically and accurately assessed and monitored, and effectively ensured that the inspected facilities are always in good condition.
The information point inspection system is composed of information points, inspection devices, communication lines, computers and software systems. The information point is a sensor that stores 8-digit hexadecimal code information engraved by laser. The number of each information point is unique and different from each other. Place the information points with different codes on the equipment or line to be inspected, and store the information point codes and corresponding placement locations in the computer. Each inspector wears an inspection device. During the inspection process, the inspectors use the inspection device to sense the information point while inspecting the equipment. Under the prompt of sound and light or vibration, it indicates that the reading is successful, that is, the information point number is read into the patrol device, and together with the time recorded by the built-in clock of the patrol device, it constitutes valid patrol data.
The inspectors regularly hand over the inspector to the management personnel, who insert the inspector into a dedicated communication line connected to the computer’s serial port, and read the inspection data in the inspector into the computer through the software in the computer. Analyze, process, count, make reports, and print out according to the assessment standards, providing managers with a scientific and accurate assessment basis, and at the same time greatly improving the work efficiency of managers.

The system is composed of American VIDEX mobile data collector, data downloader, American DALLAS i-Button information identification point and networked system management software. First, install an information identification point in the inspection area for each location (device) that needs to be inspected. Since each information identification point has a globally unique serial code, there is no duplication, so all devices can be easily identified. Inspectors carry mobile data collectors with them during the inspection, and when they arrive at each device according to the inspection plan, they read the information identification point of the device, and the serial code and reading time of the identification point will be automatically recorded in the data collector . After the inspection, the data collector will be transferred to the system management software through the data downloader in the operation room to directly generate various inspection data reports and statistical analysis reports. System management is based on the characteristics of the communication system and is professionally developed in conjunction with “uninterrupted” inspections. It has the advantages of powerful functions, simple and reliable operation.
System function introduction: The system can set multiple inspection routes (posts) and inspection plans. For each inspection route and plan, you can set the number of daily inspections, start time, time per lap, shortest time per lap, station Parameters such as the shortest time and the longest time. The system can automatically identify missed patrols, late arrivals, early arrivals, short-time and overtime records between stations, and use different colors to mark them. It can be searched individually or in combination according to various conditions such as date, time period, route (post), shift, and patrol personnel. The query includes classified reports such as normal records, missing records, and off-time records. It can automatically generate statistical analysis reports, and provide management data such as normal inspection rate, missing point rate, late arrival rate, and early arrival rate. According to the shift table of the workshop, the shift personnel who record the inspection can be automatically judged. Provide original inspection records to ensure that the records are accurate. All records provide print output function. The system also provides multi-level user authority functions, user operation logs and other security functions.
The system supports both C/S and B/S structure in terms of network. The system uses the Sqlserver database. The data of all workshops are stored in the server through the local area network. Only the client software is installed in each workshop. The data can be downloaded through the opening of permissions. You can work independently by setting up the route of the workshop, viewing and printing the inspection data. The maintenance of the database is operated on the server to ensure the safety of the data. On the server side, the iis module that comes with Windows is used to publish the inspection records on the company’s website in asp form. Leaders at all levels of the factory do not need to install any programs on the computer, and can directly access the company on any computer through IE browser. Website, enter the user name and password to view real-time inspection data and statistical reports. In this way, wherever the leader goes on business, he can get the latest inspection status only through the Internet. On the webpage, you can view the data of all workshops or certain workshops according to the authority. The data can also be selected for different routes, time periods, and record types including normal, missed tour, late, early, etc. to query, and the client software of the workshop has The same viewing function.
