Frost crack alarm monitoring method for water tank

The invention discloses a frost crack alarm monitoring method for a water tank, and relates to the technical field of frost crack protection monitoring methods for water tanks, the actual output power of a heating wire is changed by acquiring the detection temperature value of heat flow in real time and adjusting the power supply voltage of the heating wire according to the relation between the detection temperature value and a temperature monitoring interval; dynamic adjustment is carried out according to the set working parameters of the heating wire, matching adjustment is synchronously carried out on the opening degree of an electromagnetic valve of a liquid inlet port and the working frequency of an alarm under the working condition of low temperature, and therefore workers can pre-judge and obtain the possible frost crack risk of the water tank in the future in advance; and the frost crack monitoring protection effectiveness and the safety protection performance of the water tank are improved. 本发明公开了一种用
