Abstract

The utility model discloses a thermal defect detection system based on wireless temperature measurement. The thermal defect detection system based on the wireless temperature measurement comprises multi-set of wireless temperature sensors, a plurality of temperature measurement communication terminals, a plurality of industrial control computers and a temperature measurement manager. Each set of wireless temperature sensors comprise a plurality of wireless temperature sensors, and the signal output ends of the plurality of wireless temperature sensors in the same set of wireless temperature sensors are all connected with the signal input end of a same one temperature measurement communication terminal; the plurality of temperature measurement communication terminals are connected with the plurality of industrial control computers via CAN buses respectively, and the plurality of industrial control computers are all in communication connected with the temperature measurement manager via an internet. The thermal defect detection system based on the wireless temperature measurement of the utility model can fundamentally solve the major problem that the operations of an enclosed high voltage switch cabinet, such as temperature on-line monitoring, early warning, forecasting, analysis, etc, affect the safety production of a power grid for a long time, makes up the thermal defect detection insufficient of the high voltage switch cabinet, and provides scientific basis and effective means for power grid to carry out the on-line temperature measurement works of the switch cabinet and the transformer station high voltage electrical equipment.

Description

Thermal defect detection system based on wireless temperature measurement

Technical field

The utility model relates to a kind of thermal defect detection system, relates in particular to a kind of thermal defect detection system based on wireless temperature measurement.

Background technology

In recent years, the high-tension switch cabinet of Inner Mongolia Power Grid is in the heavy-duty service process, and the phenomenons such as local overheating, overtemperature happen occasionally, and causes high voltage switch cabinet fault in service.Partial fault exists quality problems to cause because of switch cubicle wood body, and the history chief reason is to lack effective means for the monitoring of high-tension switch cabinet.

At present, each power supply administration and electricity power enterprise mostly based on manual inspection, adopt the hand-held infrared thermometer to obtain the interior temperature data of switch cubicle to the detection of high-tension switch cabinet in the Inner Mongolia Power Grid.Because closed high-voltage switch gear cabinet relative complex, the interelement mutual is blocked, infrared thermometer often can't record accurately temperature data, and manual method can not realize in time monitoring and giving warning in advance, to cause the badly damaged and power outage of equipment in case go wrong, cause huge economic loss and bad social influence.

Summary of the invention

The purpose of this utility model provides a kind of thermal defect detection system based on wireless temperature measurement with regard to being in order to address the above problem.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The utility model comprises many group radio temperature sensors, a plurality of thermometric communication terminal, many industrial computers and thermometric manager, every group of described radio temperature sensor comprises a plurality of radio temperature sensors, the signal output part of a plurality of radio temperature sensors of same group of described radio temperature sensor all is connected with the signal input part of same described thermometric communication terminal, a plurality of described thermometric communication terminals are connected with a plurality of described industrial computers by the CAN bus respectively, and a plurality of described industrial computers all are connected with the communication of described thermometric manager by the internet net.

The beneficial effects of the utility model are:

The utility model can solve for a long time on-line temperature monitoring, early-warning and predicting and the analysis etc. of closed high-voltage switch cabinet from root wood affects the great difficult problem that power grid security is produced, remedy the deficiency that the high-tension switch cabinet thermal defect detects, the temperature measurement on-line work of carrying out switch cubicle and converting station high voltage electrical apparatus for electrical network provides scientific basis and effective means.

Description of drawings

Fig. 1 is the structural representation of the thermal defect detection system based on wireless temperature measurement described in the utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1: the utility model comprises many group radio temperature sensors, a plurality of thermometric communication terminals, many industrial computers and thermometric manager, every group of described radio temperature sensor comprises a plurality of radio temperature sensors, the signal output part of a plurality of radio temperature sensors of same group of described radio temperature sensor all is connected with the signal input part of same described thermometric communication terminal, a plurality of described thermometric communication terminals are connected with a plurality of described industrial computers by the CAN bus respectively, and a plurality of described industrial computers all are connected with the communication of described thermometric manager by the internet net.

The temp probe of each radio temperature sensor has unique ID number, when wireless senser sends monitored some temperature, also transmits self ID number, finishes the emission output of temp probe address date and temperature data by control module.Adopt wireless connections between sensor and the temperature measurement terminal, under the hyperbaric environment of complexity, need not increase additional wires, both made things convenient for the I﹠M of system, also reduced the impact on equipment safety operation.

Claims
