The Unmanned Machine Room Environment Monitoring System Based On PSTN

In the21st century, the economy in our country has made a rapidly development, andthis also makes the railway communication of China develop fast. In the railway computerroom, the basic communication equipment and various of communication network are putinto operation commonly, then railway communication networks also put forward intohigh quality requirements to communication service, If can not be found equipmentfailures, can make the normal business operation stagnant, and even cause major securityhidden danger, causing some immeasurable disaster and loss.Railway computer room management and maintenance need real-time remotemonitoring to advance. and this remote monitoring technology is based on the developlevel of transmission technology, computer network technology and automation controltechnology. Based on this study the collection technology, the signal transmissiontechnology, computer programming and serial interface communication, and other keytechnology, and field investigation research the local railway communication equipmentand operation room environment, its realization of the specific function: the power of thetelecom room of railway and environmental parameters, such as voltage, temperature,humidity, smoke parameters, such as real-time data acquisition and processing, when therewere parameters of the engine room more than the required standard, the system canpromptly to sound and light and other forms of the rapid alarm, maintenance personnelcan rapidly and accurately monitoring site safety treatment, greatly improved thecomputer management and along the railway maintenance level.The system satisfies the needs of our country present stage railway communicationnetwork the development, not only reduced the railway personnel working strength, butalso improve the working efficiency and maintain quality. It also can analysis theequipment operation data centrally and quantitatively., and it offers improvement anddevelopment for the network to provide reliable basis for decision-making, making themaintenance and management of communications equipment reaches to new levels.
