The present invention solves its technical matters and takes following technical scheme to realize:
A kind of high voltage electric power equip ment on-line temperature monitoring early warning system; Constitute by temperature control system, MCS, transmission system, data acquisition system (DAS), monitoring management system, self-checking system; Wherein, Data acquisition system (DAS) is made up of wireless digital temperature sensor, temperature online analyser, main industrial computer, audible-visual annunciator, printer, and wireless digital temperature sensor links to each other with main industrial computer through the temperature online analyser, and audible-visual annunciator and main industrial computer carry out communication through the RS232 mouth; Printer is connected through the parallel port with industrial computer; Transmission system adopts wireless transmission method, and said temperature control system adopts the blower fan cooling, and MCS comprises wireless digital humidity sensor, humidity controller and well heater; Self-checking system, MCS link to each other with main industrial computer respectively, and main industrial computer is connected with monitoring management system through Wireless transmission mode.
And, strong, the contact type measurement exact figure formula sensing chip of described wireless digital Temperature Humidity Sensor use antijamming capability.
And described main industrial computer possesses temperature and humidity two-way warning output, and alarm buzzing prompting can be controlled blower fan and well heater respectively.
And described each wireless digital Temperature Humidity Sensor has unique ID number, in monitoring management system, can receive all temperature informations of regularly uploading, and ID also capable of using initiatively calls the monitoring point to report temperature data.
And described self-checking system can be monitored the state of whole on-line temperature monitoring early warning system in real time, in time reports Surveillance center if any difference.
Advantage of the present invention and good effect are:
1, the present invention has the database of recollecting systematic function; Major function is the sampled data of the reference point in the some time before and after record and printing problem take place; Be used as the foundation of analysis accident; Wherein recollecting condition is to be set through accident point by the user, is set through the remembrance point by the user and recollect data.
2, sensor of the present invention adopts the super low-power consumption design, prolongs battery and can reach more than 7 years service time.
3, the present invention adopts the Software Anti-interference measure, can anti-strong electromagnetic and the interference of successive bands wireless signal.
4, system software of the present invention can be handled 65000 warning messages, the warning that can adopt sound, flash of light, change color to distinguish unidentified warning and confirmed, and warning message can record file; Or come out with printer prints; Also can browse with web browser, system software is also supported multimedia technology, and important information can adopt voice suggestion; The warning of system software draws off the fault that function allows certain type of screening, outputs to printer or file with the form of showing.
