Grain drying device with alarm resetting function

Abstract

The invention discloses a grain drying device with an alarm resetting function. The grain drying device comprises a microprocessor, a drying machine, a grain moisture sensor, a grain temperature sensor, a watchdog module, a frequency converter, an alarming module and a temperature constant value module. The microprocessor is connected with the grain moisture sensor and the grain temperature sensor. The drying machine is connected with the microprocessor through the frequency converter. The microprocessor is further connected with the watchdog module, the alarming module and the temperature constant value module. By the grain drying device, the problems that the whole grain drying system is in a dead state due to external magnetic field interference, accurate alarming cannot be given out timely, great potential safety hazard is brought to application of the grain drying system, alarm cannot be given out constantly, and great loss is caused are solved. The grain drying device with the alarm resetting function is simple in structure and good in use, and the microprocessor can realize continuous operation in an unmanned state.

Description

technical field [0001] The invention relates to a grain drying device, in particular to a grain drying device with a reset alarm function. Background technique [0002] my country is the largest grain producer and consumer country in the world, but at present most of the grain drying still relies on the traditional natural drying method, the degree of mechanization of grain drying is very low, and the harvested grain often needs to be dried. At present, when drying, because there is no alarm in the workshop to remind relevant personnel to pay attention to the change of ambient temperature, when the temperature is too high, corresponding measures cannot be taken to cool down. Even if the alarm is used, the work of the microprocessor is often interfered by the external electromagnetic field, causing the program to run away and fall into an endless loop, the normal operation of the program is interrupted, so the system controlled by the microprocessor cannot continue to work ,...

Problems solved by technology

[0003] In order to solve the problem of the grain drying device in the prior art, due to the interference of the external electromagnetic field, the entire system is in a stagnant state, and the alarm cannot be timely and accurately given. The use has brought great hidden dangers, and there are often situations where the alarm cannot be prompted, causing heavy losses. The problem
