Description
Technical field: the utility model relates to a kind of temperature measuring equipment, and especially a kind of electric terminal temperature measurement on-line device based on wireless communication technology is mainly used in electric system.
Background technology: in electric system, high pressure and UHV (ultra-high voltage) bus, high-voltage switch gear contact, the transformer station of each electric pressure, generating plant, switchgear building etc. need the temperature rise of monitoring electrical node.The method of electric terminal thermometric commonly used mainly contains two kinds at present:
First method is an inspection type: by patrolling and examining personnel's portable hand-held temperature measuring equipment (as a warm rifle), regularly the heat generating spot that hidden danger is arranged is patrolled.This method can not be monitored heat generating spot temperature rise situation in real time, can not accomplish to prevent trouble before it happens.
Another method is to use contact temperature-measuring, uses the mode of infrared communication, and the temperature value that measures is passed back local main frame.This method has solved the problem of real-time online thermometric with respect to first method, but because the restriction of this life of infrared communication, cause and must not block between transmitting and receiving, and transmit and receive and must aim at, it is not too convenient to use in specific occasions such as high-tension switch cabinets like this.
Summary of the invention: at the deficiency that prior art exists, the utility model provides a kind of electric terminal temperature measurement on-line device based on wireless communication technology.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric terminal temperature measurement on-line device based on wireless communication technology comprises local thermometric machine and temperature sensor module.Local thermometric main frame is obtained contact temperature information mainly by communication from temperature sensor module, and local processing and correction obtain the actual temperature of contact, can report to the police on the spot, or pass Control Room on duty back by the RS485 bus.
The utility model had both solved the problem of thermometric in real time, had also solved on-the-spot installation environment requirement than problem of higher, can measure the temperature of heat generating spot in real time accurately.Realized that the temperature of the high pressure of electric system and UHV (ultra-high voltage) bus, high-voltage switch gear contact (and personnel can't be approaching other danger, rugged surroundings) is carried out real-time online to be detected, through being connected with power automatic system, just can monitor running status in that center monitoring is indoor, really accomplished remote remote measurement, when the measured point temperature surpasses pre-set threshold, just send alerting signal and in time remind the relevant personnel to take measures.
Description of drawings:
Fig. 1 is the structured flowchart of temperature sensor module.
Fig. 2 is the structured flowchart of local main frame.
Embodiment:
As shown in Figure 1: temperature sensor module comprises power supply, temperature sensor, signal processing module and wireless transmitter module.
Temperature Detector is installed on the high voltage alive equipment, detects the temperature of contact point by the temperature sensor of contact, handles through numerical coding and Software Anti-interference, again by wireless mode transmission data.The digital temperature detecting device adopts initiatively thermometric working method, promptly directly temp probe is imbedded the temperature of temperature monitoring point measurement object, this mode is different from the passive mode of utilizing the infrared ray temperature-sensitive, be that infrared measurement of temperature is that contactless temperature-measuring is subject to the environment and the interference of electromagnetic field on every side, for small space, infrared temperature probe (because probe must keep certain safe distance with testee, and need be over against the surface of testee) can't be installed.
As shown in Figure 2: local thermometric main frame mainly passes through communication, obtain contact temperature information from the Temperature Detector module, by handle and proofread and correct the actual temperature that obtains contact excessively, can report to the police on the spot, or pass Control Room on duty back by the RS485 bus.Local main frame is made up of following several parts:
1, dsp system:, finish the computing and the control function of whole device mainly by 32 high-performance digital signal processors (DSP), formations such as NVRAM, Serial E 2PROM.
2, power module: be the power module of local main frame, can insert direct current 110V～340V or exchange two kinds of power supplys of 85～264V.
3, wireless receiving module: be mainly used to receive the temperature data of next transmitter module, the decoding back is by handle and proofread and correct the actual temperature that obtains contact point excessively.
4, RS485 communication module: mainly finish uploading of temperature measuring equipment data, be convenient to background monitoring and a distant place is controlled.
5, environment temperature module: can detect environment temperature, be used for contrasting the temperature rise value that can obtain electric terminal with contact temperature, this temperature rise value also can be used as the reference of electric terminal heating situation.。
6, man-machine conversation module: the input/output information of display device, the key-press status on the while scanning panel also is real-time transmitted to dsp system.
7, tripping operation output module: also can be after temperature value surpasses setting value by the tripping operation output module.
8, a plurality of Temperature Detector modules: realize the collection of temperature, and, temperature value is delivered to local main frame by wireless transmission.
