Abstract

The utility model relates to an infrared temperature on-line protection device, which is characterized in that an infrared probe is sequentially connected with a collector and a computer network, and the collector collects temperature signals measured by the infrared probe via a polling form and then uploads the temperature signals into a computer. A single chip microcomputer is arranged inside the collector and connected with a power module, a memory, an LED display module, an output module and an input module. The collector is connected with the infrared probe via a 485 bus form and connected with the computer via a 485 or local area network form. The computer can be communicated with a plurality of collectors via a polling communication form. The infrared temperature on-line protection device has the advantages that the collector controls the infrared probe to measure temperature of temperature measuring points, uploads each temperature signal into the computer, executes pre-warning and warning to each temperature measuring point according to setting values of users, and then brings convenience for watch keepers to control faults.

Description

The online protective device of infrared temperature

Technical field

The utility model relates to the temperature survey field, relates in particular to the online protective device of the infrared temperature that is applied in high-voltage electric power system.

Background technology

In high-voltage electric power system, special in handcart switch cabinet and the bus contact in the enclosed busbar, in long-time running, cause stops sending reasons such as electric oscillation, the contact of switch and bus row junction sternly generates heat because of becoming flexible, not contacting, rubescent, finally cause electric calamity, especially current unmanned substation's quantity is on the increase, and the hot stall monitoring with enclosed busbar in the handcart switch cabinet comes into one's own gradually.

The hot stall means of testing has multiple: can paste heat discoloration paper at point for measuring temperature, determine the temperature of point for measuring temperature according to the color of paper, or with wax head contact thermography point, see whether the wax head melts to determine the temperature of point for measuring temperature.It is low to appeal two kinds of simple costs of way, but low precision and can not be used for real time on-line monitoring.Though it is accurately also do not accomplish real-time monitoring than preceding two kinds of methods are easy, and inapplicable in the rival car formula switch cubicle with the enclosed busbar temperature monitoring with infrared temperature-measuring gun.Can realize real-time monitoring with infrared thermoviewer to the high-tension apparatus thermometric, but cost is very high also inapplicable to reaching in the enclosed busbar in the switch box simultaneously.All be suitable for but system is too high than complexity and cost with the high various conditions of Fibre Optical Sensor temperature measurement accuracy.Though the radio temperature measurement on-line can be realized precision measure, but real-time is not high, and because probe is installed in the metal box of sealing, radio signal can't transfer data to outside the metal box accurately and effectively and the radio thermometric needs powered battery, because high voltage bus and handcart switch cabinet can't have a power failure, the people can't be approaching, so battery can't be changed.

Summary of the invention

The online protective device of the infrared temperature that the utility model provides is collection computer technology, infrared digital temperature sensing technology, and Signal Collection Technology is the intelligent temperature on-line monitoring device of one.

The utility model is achieved through the following technical solutions:

The online protective device of infrared temperature is characterized in that infrared probe is connected with construction of computer network with collector successively, and computing machine adopts communication mode and a plurality of collector of poll to carry out communication.

Described collector inside is provided with single-chip microcomputer, single-chip microcomputer is connected with power module, storer, LED display module, output module, load module, load module is connected with bus mode with infrared probe, and output module adopts networking mode to be connected with computing machine.Described bus is 485 buses.Described networking mode is 485 networks or LAN (Local Area Network).

Compared with prior art, the beneficial effects of the utility model are: collector control infrared probe carries out temperature survey to point for measuring temperature, and each temperature signal is uploaded in the computing machine, computing machine is presented to the user in real time with the temperature of each collection point again, and each point for measuring temperature carried out early warning and report to the police making things convenient for the operator on duty in time to control fault according to user's setting value, and computer system will by the history data store of point for measuring temperature in database conveniently to watch analysis.
