It is very important for the network communication system to truly realize safe and normal operation around the clock and provide users with better quality. How to ensure it? Please see how Zhejiang Quzhou Mobile Communication Co., Ltd. successfully implemented the electronic patrol system application.
With the rapid development of my country’s modern communications industry, wireless communications have received increasing attention, their status has become more and more important, and their applications have become more and more extensive. As a mobile service operator in Quzhou, Zhejiang Province Quzhou Mobile Communication Co., Ltd., how to ensure that the network communication system can truly achieve safe and normal operation 24 hours a day, so as to provide users with better quality work is very important. Therefore, it is imperative to establish a scientific, standardized, systematic, and networked inspection and maintenance management mechanism for mobile optical cable lines, antenna feeders of base stations, iron towers and other equipment in the region.
At present, there are more than 200 base station towers in the jurisdiction of Quzhou City. The normal operation of mobile base stations will directly affect the stability of mobile signals in the jurisdiction. In order to effectively ensure the normal operation of equipment such as base station towers, regular inspections of manual equipment are particularly important.
The mobile base station inspection points mainly include: the base station’s optical cable line, the base station’s antenna feeder, iron tower and other facilities. Through the inspection of these facilities and the viewing and recording of the data of some facilities at the scene, we can grasp the operating status and usage of the system.
There are two key points in the inspection work. One is to ensure that each facility is inspected regularly, and the other is to record, summarize, and analyze the status data of the facility during each inspection.
At present, the facility inspection of the base station is to arrange personnel to inspect all the equipment. Due to the wide distribution of base stations, the large number of equipment, and the complex terrain, the task of inspection is arduous. It takes one week to inspect the base station of a line, and the facility status and related data need to be manually recorded with paper and pen. The recorded data and data analysis and summary are very difficult, and the data needs to be manually input into the computer, which is time-consuming and labor-intensive.
Based on the above-mentioned inspection status, Quzhou Mobile Communications Company introduced the ADEL-9000 digital inspection system. Due to the use of the inspection system, the inspection and information processing efficiency of the base station equipment has been greatly improved. The following briefly introduces the application of the digital inspection system.
System Overview
The inspection management system can effectively meet the needs of various inspection management such as property management, telecommunications base stations, office buildings, industrial and mining, enterprises, patrol police, detention centers, tourist attractions, museums, etc. This system is different from the traditional electronic inspection system. In addition to providing inspection time, it can also provide equipment operation records, so that the data can be downloaded to the computer conveniently and automatically analyzed and processed by professional management software. In view of the wide area of system management and the large number of equipment, the management software also introduces an electronic map management scheme, which realizes the positioning of equipment and facilitates inspection personnel to know the location and overall distribution of inspection facilities in a timely manner.
The hardware core equipment of the electronic patrol system is a handheld patrol stick and a patrol device installed on the spot. The patrol device provides a unique address code, and each facility that needs to be patrolled is equipped with a patrol device. The handheld patrol stick can read and record the address code of the patrol, and the inspector can input related equipment data into the patrol stick, so that the data of the patrol stick objectively records the time of each equipment inspection , Status and related data, etc. The data in the patrol rod can be downloaded to the management computer of the control center at any time. Through the automatic statistics and analysis of the computer, various statistical reports can be automatically generated, and the data can be archived and statistically analyzed, which provides an objective basis for the management of managers .
The patrol device installed in the base station adopts the original imported chip from American DALLS. The storage capacity of the patrol stick is 4000 records. The patrol inspector downloads the patrol data and equipment status name and other information stored in the patrol stick through the system management software. System management software.
The remote data downloader needs to be installed in each sub-management station system without LAN, local data downloader is installed in the sub-management station with local area network, the system management software and database are installed on the management center server, and the client software is installed in each sub-station.
The system management software specifically includes major functional modules such as data download, data report query, statistical analysis, and equipment map management.
Data report query: Provide basic equipment attributes, inspection information (inspection time, inspector, etc.), equipment information; provide retrieval by inspection date, site, template, inspector, equipment type, etc., which can generate multiple A variety of reports, including inspection tables, non-inspection tables, etc., query and analysis of equipment that has not been inspected for more than a certain period of time.
Statistical analysis: Provide a statistical report of the inspection situation within a specified time period or site, equipment type, template, accurately reflect the relevant situation of the inspection in the form of percentage, and count the specific number of inspections in the form of numerical value. It can analyze and count the operating status of the equipment, such as various faults and abnormal operating parameters; it can classify and summarize the attributes of the equipment, such as different manufacturers, different commissioning dates, and so on. The static and dynamic management of the equipment can be easily realized through the report of the system. The software allows the user to set the device name corresponding to the patrol device, preset the data, and establish the device database.
Electronic map management: Based on the map of the area, including independent layers such as terrain, roads, units, pipelines, facilities, etc., accurately mark the location of related equipment that needs to be inspected and managed. Local area network users can view data through the client program, and non-local area network users can view data through web pages through the WAN.
implementation plan
This mobile communication industry inspection management system shall inspect and manage more than 200 base stations in Quzhou and surrounding towns. The base stations are all unattended outdoors, distributed in the entire area, and there are 7 sub-stations under them. Each sub-station arranges 20 inspection personnel. All 7 sub-stations need to set up data download points, and the inspection data of the 7 sites need to be centralized to the management center, and the inspection data shall be released within the company for use by various management departments. The entire implementation plan is composed of a patrol stick, a patrol device, a controller (with a remote telephone line data downloader), a management computer and networked system management software (see Figure 1).

The inspection device, considering that the equipment (base station) is basically outdoors and the environment is relatively harsh, so the inspection device with strong environmental applicability is selected with waterproof, shockproof, explosion-proof, and anti-destructive capabilities.
The system selects the Sqlserver database, and installs the database on the server of the management center. The system covers the entire Quzhou area, involving 7 management sub-stations. Seven remote data downloaders use telephone lines to transmit the inspection data to the management center server. For sites connected to the local area network, install the client program and transmit data to the server through the local area network to achieve the purpose of centralized management and unified processing (see Figure 2).

The management departments of the company can choose the client mode, or directly use the web browser to query and manage the inspection data and equipment data. The system manager compiles the distribution of all base stations into several sections in the management software, and formulates corresponding inspection plans for each section.
The patrol personnel carry the handheld patrol stick, and read the device patrol device information (the unique device code) after arriving at the designated device. The patrol personnel complete the device data input according to the status of the device, and then read the patrol device information. Such a complete inspection record including inspection time, residence time, equipment data and status is stored in the inspection stick.
The inspection personnel return to the site every day and upload the data to the management center server. The system management software automatically analyzes the data and generates various reports, including inspection reports, equipment data reports, equipment status reports, etc. Each management department can View data in real time by way of web pages.
Effect
After Quzhou Mobile Communications Company installed and used the digital inspection management system, not only could the quality of line inspection and maintenance work be guaranteed, but the line inspectors had corrected their work attitudes and increased their enthusiasm for inspections, bringing a whole new look to the inspection work. The specific effects of scientific management methods are shown in the following aspects:
·Because the system management software is powerful, it can check when and which lines the patrol personnel of each maintenance station go to, especially whether the important areas arrive within the specified time, and whether the patrol personnel are in place, etc. It can be easily displayed in various query reports of the management software, which fundamentally eliminates the laziness and off-duty phenomenon of inspectors, and can detect hidden equipment hazards in time and perform maintenance and repair quickly;
·Maintenance headquarters can flexibly dispatch inspection personnel according to specific conditions, handle emergencies in time, and make inspection and maintenance work plans in the system management software for the specific conditions of each maintenance station to achieve real-time supervision and management And assess the working conditions of each maintenance station;
·It can effectively prevent malicious sabotage by some criminals and illegal organizations. As long as inspectors conduct inspections strictly on time and on a point-by-point basis, they can effectively deter criminals and prevent sabotage incidents, thereby ensuring that network signals are not disturbed ( Especially during major holidays);
·All kinds of data reports can be obtained through this inspection system, which can reflect the daily work records of inspectors scientifically and realistically, so that the rewards and punishments of inspectors can be objective and fair. Not only has it established the prestige of the management, it has also increased the enthusiasm and sense of responsibility of the inspectors.
