Problems solved by technology

The switch box 5' of the detector alternately controls the opening and closing of the electronic switch assembly 8'. When the electronic switch assembly is in the open state, the switch box 5' detects the change in the resistance of the linear temperature sensing element. When the detected resistance exceeds the set When the alarm threshold is reached, the detector sends out a fire alarm signal. When the electronic switch assembly is in the closed state, the conversion box 5' detects the resistance value of the linear temperature sensing element. When the detected resistance value is too large, the detector sends out a fault alarm signal. The disadvantage of the detector is: the terminal is equipped with an electronic switch assembly 8', and two parallel detection conductors 1', 2' are used as the power line of the terminal electronic switch assembly 8', and at the same time are the detection conductors 1', 2' The wire body resistance detection line has complex and cumbersome logic, high production cost and low reliability

Embodiment 2

[0013] Example 2, a linear temperature sensor with a gas discharge tube terminal, see Figure 4 A resistor 7 is connected in parallel at the end of the microcomputer modulator 5, on the input end of the temperature-sensing cable or between the two metal detection conductors 1 and 2, and the purpose of increasing the resistance 7 is to reduce the distance between the two metal detection conductors 1 and 2 of the temperature-sensing cable. The resistance value between them reduces the magnification of the detection electric signal, enhances the anti-electromagnetic interference ability of the linear temperature sensor, and improves the temperature sensing alarm accuracy of the linear temperature sensor of the present invention. Its working principle is identical with embodiment 1.

Abstract

The invention aims at providing a line type temperature sensor of a terminal with a gas discharge tube. After the terminal falls off or is disconnected, or a temperature-sensing cable detects that a conductor is disconnected, a micro computer modulator of the line type temperature sensor can normally detect the temperature-sensing cable well connected with the micro computer modulator. The line type temperature sensor of the terminal with a gas discharge tube is characterized in that two ends of the temperature-sensing cable are respectively connected with the micro computer modulator and the gas discharge tube of the terminal to form an electric signal acquisition circuit of an open circuit of the terminal. The obvious advantages are that the terminal is only provided with the gas discharge tube, therefore, the micro computer modulator has simple control and detection logics, the line type temperature sensor has a simple structure, the production cost is lowered and the reliability is improved.
