The invention provides a temperature control method for a multi-core CPU (central processing unit) fixed code reader, which comprises the following steps of: setting three CPU temperature control points, reading the CPU temperature every TI time period, and monitoring and adjusting the CPU temperature of the code reader in real time. The CPU load can be obviously reduced by reducing the decoding thread count, and the lighting lamp turn-on time can be shortened by reducing the image output frame rate; therefore, the temperature of the code reader body and the temperature of the CPU can be effectively controlled by reducing the image frame rate and the decoding thread count, the highest temperature of the code reader body and the temperature of the CPU are prevented from surmounting the third temperature control point, and the third temperature control point is maintained at a temperature value capable of ensuring the working safety and the working performance for a long time. 本发明提供一种多核CPU固定式读码器的温度控制方法，设置三个CPU温
