[Abstract]:Base station moving-ring monitoring equipment is an indispensable monitoring equipment to ensure the normal operation of base station. With the continuous increase of base stations, the demand for monitoring equipment is also increasing, and the existing monitoring equipment in the base station monitoring ability is increasingly unable to meet the requirements of modern intelligent monitoring, and also needs to be updated. Therefore, it is necessary to design a new generation of base station moving-ring monitoring equipment. The device can not only monitor the environment of base station such as temperature and humidity, but also monitor the intelligent equipment of base station. At the same time, the device can have the ability to connect to video camera and the ability of 3G / 4G. Considering that the mobile ring monitoring equipment is in the base station where the electromagnetic environment is relatively bad, the device interface is often subjected to strong electromagnetic interference, so in order to ensure the reliable operation of the monitoring equipment, It is necessary to improve the EMC protection level of the equipment in the design of hardware circuit to ensure that the equipment can run reliably for a long time. Based on the requirements of equipment performance and electromagnetic protection, a new hardware platform of moving ring monitoring system is designed. The whole scheme design of moving ring monitoring system should conform to the standards of telemetry, remote adjustment, remote control and remote communication, and meet the monitoring requirements of base station equipment. The system is designed with C / S two-level architecture. The data acquisition and transmission are realized by multiple processors at the data acquisition end of the system. The signal of the sensor is collected and controlled by MC9S08 MCU, and the signal of the sensor is collected and controlled by MC9S08. Arm control board is used to monitor intelligent equipment. In the design of the circuit, it is necessary to analyze the type of the equipment and the data type of the environmental monitoring quantity, and to design the corresponding collection circuit to realize the monitoring function. The monitoring equipment is in the base station, but the electromagnetic environment of the base station is relatively bad, so the EMC design of the monitoring system circuit is required higher, especially the anti-surge design of the port input. Through the simulation and experiment of the circuit, the design scheme needs to meet the requirements of the latest specifications. According to the design requirements of the base station monitoring hardware platform, this paper mainly includes the following aspects: (1) analyzing the hardware interface type that the monitoring equipment needs to support, Design the whole hardware platform access scheme; (2) analyze the collection object type and data communication transmission characteristics of the monitoring system, compare and select the appropriate functional circuit, (3) designing appropriate surge protection circuit for the acquisition port. Combined with the electrical characteristics of acquisition circuit and communication circuit, the characteristics of surge protection technology are analyzed. At the same time, a PSCAD surge protection model is established to study the related characteristics of surge protection topology. Compare the simulation parameters to select appropriate surge protection circuit and protective devices to achieve reasonable safety protection. (4) the design of DC power EMI filter. The problem of conduction disturbance in DC-DC power supply is analyzed, and the high-frequency equivalent simulation model of PSpice is established. The simulation and experimental analysis optimize the component parameters to make the monitoring equipment with filter reach A level. (5) the realization of bottom software is completed. At the same time, the performance of the prototype is tested.
