Abstract
The utility model relates to a laser temperature alarm device comprising a housing. The device is characterized in that a main control processing unit, a signal emitter, a signal receiver and a battery are arranged on the inner wall of the housing; light shielding covers are arranged on the signal emitter and the signal receiver; and a thermosensitive plate is arranged at the back of the signal receiver. According to the utility model, the signal emitter is used to emit laser signals uninterruptedly; and the laser signals are received by the signal receiver that is arranged on the thermosensitive plate. When the external temperature rises and thus the thermosensitive plate is deformed, the strength of the laser signals received by the signal receiver is weakened or even eliminated; a signal alarm is triggered to give an alarm sound and sends information to a terminal processor; and instant communication software is used to realize remote alarming.
Description
Technical field
The utility model relates to the monitoring field, particularly a kind of laser temperature warning device.
Background technology
Exploitation and processing site at 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 measure usually and rely on the electric signal transmission in the alarm device course of work of temperature, in case break down, probably owing to electric leakage produces spark, cause flammable and explosive substance burning even blast, cause enormous economic loss and casualties.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of laser temperature warning device, can Instant Messenger (IM) software realize remote alarms.
In order to achieve the above object, the technical solution of the utility model is: a kind of laser temperature warning device, comprise shell 1, shell 1 inwall is provided with main control processing 8, signal projector 2, signal receiver 5 and battery 7, be provided with light shield 3 on signal projector 2 and the signal receiver 5, the back side of signal receiver 5 is provided with temperature-sensitive plate 4.
Described temperature-sensitive plate 4 uses two kinds of different materials processings of thermal expansivity to become double-layer structure up and down.
The utility model can Instant Messenger (IM) software be realized remote alarms.
Description of drawings
Accompanying drawing is mechanical schematic of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing, a kind of laser temperature warning device comprises shell 1, and shell 1 inwall is provided with main control processing 8, signal projector 2, signal receiver 5 and battery 7, be provided with light shield 3 on signal projector 2 and the signal receiver 5, the back side of signal receiver 5 is provided with temperature-sensitive plate 4.
Described temperature-sensitive plate 4 uses two kinds of different materials processings of thermal expansivity to become double-layer structure up and down, and the measure that thermal grease conduction etc. reduces thermal resistance is taked to smear in junction in the middle of it.
Principle of work of the present utility model is: this utility model is installed in required installation site, after connection battery 7 is started working, signal projector 2 will be penetrated laser signal, signal receiver 5 constantly receives signal, when this ambient temperature rises, the temperature-sensitive plate 4 that is positioned at signal receiver 5 bottom surfaces will absorb heat, and then deform, the laser signal intensity that causes signal receiver 5 to receive weakens even disappears, signal alarm 6 sends warning under the control of main processing controller 8, and send information by radio reception generator 9 simultaneously and give terminal handler 10, realize remote alarms by Instant Messenger (IM) software.
Claims (2)
