Based On The Technology Of Low Voltage Power Carrier Room Design Of Data Acquisition System

With the development of integrated circuits, our country entered the era of rapid information technology. For the network environment of communication network, the requirements are high, such as stable network running, wide coverage and so on. Computer room is an important node in the communication network, computer room once appear, fault, will not only affect the operation of the network environment, can also cause data transmission interrupt, was even possible system paralysis. So the security of the running environment of the telecom room safe, reliable, has become a key in communication network.This topic is kyle company and Harbin northeast agricultural university in cooperation projects.According to the company for the request of the telecom room, the design of the whole control system adopts modular design method, realized the communication machine room temperature, humidity and wind speed of remote collection system functions. According to the standard of the engine room, the temperature is best maintained at 25~18℃. The design of the environmental detection system in the computer room, with the STC12C5A32S2 microcontroller as the core, the wind speed sensor uses WD411 X, the temperature, the humidity measurement uses the digital sensor AM2301. Low voltage power carrier is characteristic of the power system communication mode, due to the power line and signal line one, without laying a new line. Carrier is a specific frequency radio waves, in wireless communication technology we use carrier to transfer information, digital modulation signal to a high frequency carrier and then in the air transmitting and receiving. The design of mining each acquisition node on the LCD screen will display the data collected by the nodes, nodes collect data by the carrier module to the host, the host will data transmitted to the host computer and various sensors collect data will in the PC interface display.In order to verify the feasibility of the design scheme and the performance of the carrier, the carrier is tested in the engine room. Through the analysis of test results, and finally confirmed in this paper, the development of carrier strong anti-interference ability, stable and reliable work, simple and convenient operation, satisfy the requirements of the remote data acquisition.
