Abstract

The invention relates to the field of temperature measurement, in particular to a temperature monitoring method and system for a heat dissipation ignition coil and a medium, and the method comprises the steps: carrying out the dimension reduction of the coil temperature and the radiator temperature into a monitoring vector, and obtaining the balance temperature of the monitoring vector; when the coil temperature is larger than the preset early warning temperature, dimension reduction is conducted on the coil temperature and the radiator temperature to obtain abnormal vectors, and meanwhile the monitoring vector obtained last time is recorded as a normal vector; recording a plurality of equilibrium temperatures presenting an increasing trend according to a time sequence in the equilibrium temperatures of all the monitoring vectors as reference equilibrium temperatures, and obtaining a first dimension and a second dimension according to the continuity and discreteness when the value of each dimension of all the monitoring vectors changes along with the reference equilibrium temperatures; and performing temperature early warning by using the difference between the abnormal vector and the normal vector in the first dimension and the second difference. The problem of false early warning caused by carbon deposition and dust deposition of the radiator is avoided.
