Description
Technical field
The utility model relates to supervisory system field, specifically a kind of temperature electronic supervisory system.
Background technology
There is the defect that cannot set the bound definite value of monitoring temperature in prior art for the warning system of environmental monitoring, and purposes is single, cannot realize the functions such as report data output.And present supervisory system needs to use temperature sensor, in order to realize the rapid detection of temperature, traditional mode adopts Heat Conduction Material to be encapsulated in probe by thermistor, but the measuring accuracy of thermistor cannot promote further.
Utility model content
The purpose of this utility model is the temperature electronic supervisory system providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of temperature electronic supervisory system, comprise touch-screen, PLC, temperature sensor, relay and alarm, described touch-screen and PLC are interconnected, described temperature sensor connects PLC, described PLC is connected with relay, described relay is connected with alarm, described alarm is audible-visual annunciator, temperature sensor comprises protective housing and thermistor, described thermistor is provided with several, thermistor is located in protective housing, the outside of thermistor is provided with conducting adhesive material, the outside of described conducting adhesive material is provided with heat insulating package material, described thermistor is connected with wire, the outside of described wire is provided with heat-conducting insulation material.
As further program of the utility model: described insulative potting material is PE hot melt adhesive.
As further program of the utility model: described conducting adhesive material is heat-conducting silicone grease or the tackifier through conductive filler.
As the utility model further scheme: described wire is fixed on the inner side of protective housing.
Compared with prior art, the beneficial effects of the utility model are: the utility model temperature sensor testing environment temperature also sends touch-screen to by PLC after temperature signal is converted to electric signal, electric signal is changed into readable temperature and shows in real time and generate historical temperature warning by touch-screen, record alarm condition simultaneously, temperature bound is preset by PLC, alerting signal is sent with sensing touch screen, alerting signal will arrive audible-visual annunciator after relay, structure is simple, debugging is convenient, low cost of manufacture, stable performance, can ensure that production technology is carried out more smoothly.Be provided with some thermistors, solving knows clearly interferes with each other situation between several thermistor, is isolated by thermal signal, independently obtains non-interfering thermal signal, avoid the impact of the heat signal being subject to single direction or position.Although the aisle spare being conveyed into thermistor of thermal signal diminishes, greatly can improve the precision of temperature sensor, the heat conduction transmission of wire is taken into account among the design of temperature sensor simultaneously, improve the sensitivity of temperature sensor, reduce temperature delay.Led by counter radiation and anti-pass, stop the interference of several thermal signal further.
Accompanying drawing explanation
