I. Overview With the rapid development of the communications industry, equipment installed in remote mountainous areas of mobile communication base stations: air-conditioner outdoor units, antenna feeders, storage batteries, base station bus boards, outdoor transformers, and communication cables for erection in the field have been stolen. To strengthen the market With regard to competitiveness, improving labor productivity and network maintenance, there is an urgent need to address security issues in communications equipment.
Based on the above situation, Zhengwei designed a security solution for the GSM/GPRS platform: upload the warning information of each distributed communication point to the relevant operation and maintenance personnel of the center through GSM/GPRS/ voice, MMS, and SMS channels, so that The alarm information is processed in a timely manner to improve the reliability of the communication network, which makes the management work more efficient and scientific, and brings convenience and convenience to the daily work of the management staff. It also provides more effective public security agencies and communication operators to crack down on crimes. Technical equipment.
Second, the principle of the communication program 1. Through the GSM/GPRS front-end products on the scene of the investigation SMS, telephone, MMS and other communication site warning information to the central engine room and related leadership and maintenance personnel and make treatment;
2. When alarm occurs, a siren alarm will be sounded, and at the same time, the preset six groups of alarm calls will be automatically cycled through the GSM/GPRS mobile communication network to intelligently identify whether the staff will answer the alarm. Once the alarm is answered, the number will no longer be dialed; and English text messages to pre-set workers on the phone, identify the alarm base station through the text message content, at the same time the alarm center network alarm, the central computer room can be remotely armed through the phone, disarm, monitor the scene;
3. The system itself has a video recording function, from which defense zone the criminals enter the scene to commit crimes, the corresponding on-site camera captures color pictures, and sends MMS at the same time. At the same time, the camera on the road carries out video recording, and the video file is stored in the product's own SD card. Here, the recording time can be freely set according to the actual situation, and it can also be controlled remotely;
4. The operation of MMS, traditional alarm, because there is no picture to confirm, once the front end of false positives, there is no way to confirm whether the false positive, the system can be controlled in the back-end, the product can connect four-way camera, you can Control any one way to send MMS messages to confirm whether the pictures are false positives. At the same time, there is a direct MMS message for the criminals' faces that is transmitted and stored as evidence.
Third, the base station monitoring system structure Base station monitoring system includes Zhengwei GSM/GPRS/CDMA terminal alarm platform and alarm center.
1. GSM/GPRS/CMA Terminal Alarm: Host 1, Hand Pen 1, Remote Controller 2, Door Magnet 1, Hemisphere Indoor Camera 1 and some supporting wires, siren 1, antenna 1, camera power, host power, Host built-in lithium battery;
2. Receiving the police center: The center receives a police station and picks up the police center software.
IV. System Advantages 1. Alarm Timeliness: When the base station is stolen, the extension will directly notify the relevant party listening by the alarm information through the voice and SMS is dark, and accurately inform the location of the base station and the name of the alarm sensor, to facilitate the relevant management personnel of the base station Fast speed to understand the scene and rush to the scene, managers can remotely modify and set extension parameters through SMS;
2. Wide monitoring range;
3. Easy installation, full wireless transmission, low maintenance cost;
4. With prevention and seismic functions: When the base station is stolen, the extension automatically starts the alarm and informs the relevant personnel of the alarm message through voice and SMS. Active (or passive) starts the siren, turns on the light to perform the earthquake photography, and directly monitors the site. Prompt criminals and stop crimes in a timely manner;
5. Forensics: When the extension alarms, the camera can continuously take pictures of the scene and transfer the pictures to the monitoring center. Pictures and video clips can also be stored.
