The invention discloses a power control method and system for improving the electromagnetic compatibility of instrument control equipment, and the method and system are used for terminal equipment. The method comprises the steps: building a power control monitoring protocol for improving the electromagnetic compatibility of the instrument control equipment with a base station; monitoring and obtaining broadcast information of a base station, wherein the broadcast information comprises power control information which is sent by the base station according to the power control monitoring protocoland is provided with a power threshold value; and setting a corresponding power value according to the power threshold value in the power control information so as to adjust the transmitting power ofthe terminal equipment. By adjusting the transmitting power of the terminal equipment, the electromagnetic interference to the instrument control equipment is reduced, so that the electromagnetic compatibility of the instrument control equipment is efficiently improved, the implementation cost is lower, and the application range is wider.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a power control method for improving the electromagnetic compatibility performance of instrumentation and control equipment, and a power control system for improving the electromagnetic compatibility performance of instrumentation and control equipment. Background technique [0002] Electromagnetic Compatibility (EMC, Electromagnetic Compatibility) refers to the ability of a device or system to operate in compliance with the requirements in an electromagnetic environment without causing unbearable electromagnetic disturbance to any other equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic disturbance (Electromagnetic Disturbance) generated by the equipment during normal operation cannot exceed a certain limit; Electromagnetic disturbance has a certain degree of immunity, that is, electromagnetic suscept...
