Aiming at the controlling requirement of transmitters in wMPS network measurement field, a centralized control system for transmitters based on Internet of things technology has been proposed. System including transmitter node layer, network layer and application layer. Making use of wireless sensors and micro controllers to realize the controlling and communication function of transmitter nodes. These nodes access to the industrial network regionally. Measuring PC server can uniformly manage these transmitters. Through experiments, test results show that the transmission delay is small, controlling system can complete controlling and response process 3 times per second and system runs stably. Moreover, it has strong scalability, can well improve the work efficiency in measurement fields.
