Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Basic scheme of the present invention is: as figure 1 As shown, the present invention uses the corresponding terminal of the measurement interface as the detection terminal, connects the detection terminal to the detection unit, and judges whether the temperature measurement channel corresponding to the measurement interface is opened or not by detecting the voltage of the terminal.

[0017] Further, the detection unit includes a pressure measuring circuit and a first multi-way selection switch, the current flowing through the measurement terminal is output to the pressure measurement circuit through the first multi-way selection switch, and the first multi-way selection switch is used to realize multi-channel detection, and It can greatly reduce the number of circuit components and operating costs, and is very suitable for industrial promotion and app...

Abstract

The invention relates to a multi-channel temperature measurement circuit. A thermal resistor is an element converting temperature changes into resistance value changes, is generally applied to temperature measurement devices and is widely used in industrial process control and measurement systems. To solve the problem that efficient thermal resistor detection can not be achieved in a traditional multi-channel temperature measurement circuit, the novel temperature measurement circuit is designed; the novel temperature measurement circuit is provided with a detection unit, has the function of detecting the working state of the thermal resistor and conforms to practical application better.

Description

technical field [0001] The invention relates to a novel temperature measuring circuit. Background technique [0002] Thermal resistance is an element that converts temperature changes into resistance value changes. It is mostly used in temperature measuring devices and has been widely used in industrial process control and measurement systems. In practical applications, multiple thermal resistances are generally required to work at the same time. , in the traditional multi-channel temperature measurement circuit based on thermal resistance, multiple electronic switches are generally used to select multiple thermal resistances to output electrical signals. Due to the large number of thermal resistances, if one or several thermal resistances If the wiring fails, it needs to be checked one by one to detect the fault, which will not only take a lot of time and labor, but also affect the normal operation of the equipment, which will lead to the decline of the overall benefit of t...
