    2.1.1Equipment Composition

    The front-end acquisition equipment of electronic fence consists of host computer, antenna and related cables. The host computer integrates three acquisition modules, which can collect 2G mobile phones at the same time.Signature sum4G mobile phone signature and MAC address of all mobile phones. The host computer is composed of acquisition module, control module, buffer module, transmission module, power amplifier module, power supply module, lightning protection module, filter combining module, connecting cable and so on. The integrated design (size 513*465*235mm) is adopted. When deployed, only the host computer is connected to the antenna, then the signal acquisition can be carried out by connecting the power supply. The set of data is transmitted to the information center in real time by wired or wireless mode to realize the comprehensive application of data.

    The main equipment is decomposed. The hardware of the front-end acquisition equipment consists of transmitting antenna, receiving antenna, power amplifier, Unicom acquisition module, mobile acquisition module, control module, transmission module and power module.


    (Composition diagram of acquisition equipment system)

    Ø antenna

    Antenna is used to transmit the signal of acquisition equipment, and receive the signal of mobile station and operator network. According to the deployment of acquisition point, omnidirectional antenna or directional antenna can be selected.

    Ø GSMAcquisition module/ LTE acquisition module

    GSM acquisition module is responsible for collecting IMSI/IMEI information of China Mobile and China Unicom GSM mobile phones, while LTE acquisition module is responsible for collecting China Mobile and China Unicom GSM mobile phones.Unicom and China TelecomLTEMobile phoneIMSI information.

    Ø power amplifier

    The power amplifier is responsible for controlling the intensity of the transmitted signal. The power amplifier can select different power magnitude amplifier modules to control the input power of the amplifier, control the range of the power adjustable, and control the reasonable output of the transmitted signal of the acquisition equipment according to the actual network environment.

    Ø control module

    The control module is responsible for controlling the work of the acquisition module and the storage of the acquisition data, including setting the working frequency, re-entry time, acquisition interval and other parameters of the acquisition module. After acquisition of mobile station information, the acquisition module sends the data to the control module. The control module has its own storage function and can classify and save the data.

    Ø Transmission module

    The transmission module is responsible for transmitting the data collected by the acquisition equipment to the back-end server, and receiving remote control and telemetry commands from the back-end server.

    Ø Structural Design

    The acquisition module, control module, transmission module, power amplifier and power supply are integrated together. The equipment adopts all-aluminium alloy radiator shell structure. It has the advantages of small size, strong heat dissipation effect and convenient installation. The interface of acquisition equipment includes one.220V power cord, two transmit antenna interfaces,One rootGPS receiving antenna and an Ethernet interface, transmitting antenna need to be erected.
