Embodiment 1

[0040] see figure 1 , this embodiment provides a multi-point temperature measurement terminal with a stability enhancement mechanism and low power consumption, and the terminal is used for multi-point temperature measurement of granaries. The terminal adopts the concept of functional classification, including the station guard system and the collection system, and designs the coordination control mechanism of the two. The station guard system provides stable working voltage conditions for the acquisition system through two voltage detections and judgments, and the acquisition system will only collect multi-point temperature data when the voltage is stable. Among them, the station guard system includes a main control module 1, a voltage detection module, a step-down module and a relay module, and the acquisition system includes a main control module 2, a driving circuit and multiple temperature sensors. In this embodiment, both the main control module 1 and the main control mo...

Embodiment 2

[0095]This embodiment provides a multi-point temperature measurement method with a stability enhancement mechanism and low power consumption, which is applied to the multi-point temperature measurement terminal with a stability enhancement mechanism and low power consumption in Embodiment 1 . Wherein, the temperature measurement method includes the following steps:

[0096] Detect the effective value of the power supply voltage of the power supply supplying power to the multi-point temperature measurement terminal every preset time;

[0097] Judging whether the effective values ​​of the power supply voltage detected by the voltage detection module for two consecutive times are all within a preset fluctuation voltage range, and judging whether the voltage change rate of the power supply voltage is less than a preset change ratio;

[0098] When the effective value of the power supply voltage detected by the voltage detection module for two consecutive times is within the preset...

Embodiment 3

[0103] This embodiment provides a computer terminal, which includes a memory, a processor, and a computer program stored in the memory and operable on the processor. The steps of implementing the multi-point temperature measurement method with a stability enhancement mechanism and low power consumption in Embodiment 2 when the processor executes the program. When the method of Embodiment 1 is applied, it can be applied in the form of software, such as a program designed to run independently and installed on a computer terminal. The computer terminal can be a computer, a smart phone, a control system, and other Internet of Things devices. The method in Embodiment 2 can also be designed as an embedded running program, installed on a computer terminal, such as a single-chip microcomputer.

Abstract

The invention discloses a multi-point temperature measurement terminal and a method with a stability enhancement mechanism and low power consumption. The terminal includes a guard system and a collection system. The station guard system includes main control module 1, voltage detection module, step-down module and relay module, and the acquisition system includes main control module 2, drive circuit and multiple temperature sensors. The voltage detection module is used to detect the effective value of the power supply voltage. Once the main control module judges whether the effective value of the power supply voltage for two consecutive times is within the preset fluctuation voltage range, whether the voltage change rate is less than a preset change ratio, and at the same time, it determines that the power supply voltage is in a stable period, and drives the voltage detection module to stop detection , and drive the acquisition system to measure the temperature in the stable period, otherwise, it is determined that the power supply voltage is in the voltage fluctuation period. The main control module 2 drives multiple temperature sensors to collect temperature information of multiple points. The invention greatly reduces the power consumption, improves the stability of the terminal, prevents the sensor from being burned, and always maintains the correctness of the serial number.

Description

technical field [0001] The present invention relates to a temperature measurement terminal in the technical field of granary temperature collection, in particular to a multi-point temperature measurement terminal with a stability enhancement mechanism and low power consumption, and also to a multi-point temperature measurement terminal with a stability enhancement mechanism and low power consumption. point temperature measurement method. Background technique [0002] The safety of grain reserves is related to the stability of the country. In the field of grain situation monitoring and control, temperature is an important monitoring parameter for the environment in the granary, which plays a vital role in ensuring grain storage. The granary managers need to know the temperature of each grain point inside the granary at all times, so as to make corresponding management and maintenance of the grain storage temperature. With the continuous development of the Internet of Things,...
