Abstract
A laser temperature alarm comprises a shell. The laser temperature alarm is characterized in that the inner wall of the shell is provided with a main control processing unit, a signal transmitter, a signal receiver and a battery; the signal transmitter and the signal receiver are respectively provided with a light shading hood; and the back surface of the signal receiver is provided with a heat sensitive plate. According to the laser temperature alarm of the invention, the signal transmitter is adopted to continuously emit laser signals which are received by the signal receiver; the signal receiver is mounted on the heat sensitive plate; when external temperature rises, the heat sensitive plate is deformed, the strength of the laser signals received by the signal receiver is weakened and even vanished, and a signal alarm is triggered to emit alarm sound and send information to a terminal processor at the same time, and remote alarm can be realized through instant communication software.
Description
Technical field
The present invention relates to monitoring field, particularly a kind of laser temperature alarm.
Background technology
In exploitation and the processing site of the flammable and explosive substances such as oil and natural gas, the temperature monitoring of these dangerous substances is the problem that people quite pay close attention to always, but conventionally measure in the alarm device course of work of temperature and rely on electric signal transmission, once break down, probably because electric leakage produces spark, cause even blast of flammable and explosive substance burning, cause huge economic loss and casualties.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of the present invention is to provide a kind of laser temperature alarm, can Instant Messenger (IM) software realize remote alarms.
In order to achieve the above object, technical scheme of the present invention is: a kind of laser temperature alarm, comprise shell 1, on shell 1 inwall, be provided with main control processing 8, signal projector 2, signal receiver 5 and battery 7, on signal projector 2 and signal receiver 5, be provided with light shield 3, the back side of signal receiver 5 is provided with temperature-sensitive plate 4.
Described temperature-sensitive plate 4 uses the different bi-material of thermal expansivity to be processed into upper and lower double-layer structure.
The present invention can Instant Messenger (IM) software realize remote alarms.
Brief description of the drawings
Accompanying drawing is mechanical schematic of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
With reference to accompanying drawing, a kind of laser temperature alarm, comprises shell 1, is provided with main control processing 8, signal projector 2, signal receiver 5 and battery 7 on shell 1 inwall, on signal projector 2 and signal receiver 5, be provided with light shield 3, the back side of signal receiver 5 is provided with temperature-sensitive plate 4.
Described temperature-sensitive plate 4 uses the different bi-material of thermal expansivity to be processed into upper and lower double-layer structure, and thermal grease conduction etc. is taked to smear and reduce the measure of thermal resistance in junction in the middle of it.
Principle of work of the present invention is: this invention is arranged on to required installation site, after connection battery 7 is started working, signal projector 2 will be penetrated laser signal, signal receiver 5 constantly receives signal, in the time that this ambient temperature rises, the temperature-sensitive plate 4 that is positioned at signal receiver 5 bottom surfaces will absorb heat, and then deform, cause the laser signal remitted its fury that signal receiver 5 receives even to disappear, under the control of main processing controller 8, signal alarm 6 sends warning, and send information to terminal handler 10 by radio reception generator 9 simultaneously, realize remote alarms by Instant Messenger (IM) software.
