The novel interlaced bidirectional constant-voltage low-power-consumption temperature measurement system is characterized in that an interlaced bidirectional control circuit, a constant-current constant-voltage control circuit and a beam excitation type logic amplifying circuit are further connected to the output end of the temperature acquisition circuit and the output end of the signal conversion circuit in series, wherein the constant-current constant-voltage control circuit is connected with the output end of the interlaced bidirectional control circuit, and the beam excitation type logic amplifying circuit is connected with the interlaced bidirectional control circuit and the constant-current constant-voltage control circuit. According to the novel interlaced bidirectional constant-voltage low-power-consumption temperature measurement system, the constant-current constant-voltage control circuit is additionally arranged, so the stability of the working current and the working voltage of the system in the using process can be ensured, and the accuracy and stability of measured data can be improved remarkably.

Description

technical field [0001] The invention relates to an electronic measuring instrument, in particular to a novel amplified field strength detection low power consumption temperature measurement system. Background technique [0002] At present, there are mainly two types of body temperature measuring instruments on the market, one is a traditional mercury thermometer, and the other is an electronic thermometer. Although the traditional mercury thermometer has been used for a long time, it has defects such as inconvenient measurement, fragility, and long measurement time, which is not convenient for long-term continuous body temperature monitoring. Although the electronic thermometer is easy to detect, one of its core requirements is to have low power consumption performance to make the product practical. In order to achieve low power consumption, the electronic thermometer is required to enter the low power consumption state in the non-measurement state, and then enter the measu...
