The invention discloses a method resisting strong electromagnetic field interference for monitoring parameters of a transformer substation and relates to the technical field of internet application. The system consists of a slave computer, a main computer, a cloud storage platform and an upper computer. The slave computer uploads collected data to the main computer through an industrial-level SI4432 wireless communication module, the main computer receives the data and sends the data to the cloud storage platform through an NB-IoT wireless communication technology, and the main computer can also achieve the data mutual transmission with the upper computer of a monitoring center through a RS485 serial port. And the upper computer of the monitoring center takes out the data from the cloud storage platform through a HTTP protocol. Radio communication between NB-IoT and SI4432 avoids an electromagnetic interference frequency band in the transformer substation and the safety and reliabilityof data transmission are improved. CPU control modules of the slave computer and the main computer both select STM32L431 with high speed and low power consumption, so that the power consumption can be reduced and the data transmission rate can be improved; the cloud end is adopted to store a large amount of data in the system, which provides convenience for the re-development of the system.
Description
technical field [0001] The invention relates to the application field of Internet technology, and provides a parameter monitoring method for a substation in a strong electromagnetic field environment, in particular to a parameter monitoring method for a substation to resist strong electromagnetic field interference. Background technique [0002] With the rapid development of my country's electric power industry, my country has built a giant complex power grid with the highest voltage level in the world. Due to the complexity and particularity of the electromagnetic environment of the power system itself, wireless communication technology is more widely used in the substation environment. However, the typical electromagnetic interference generated by the substation is in the frequency band of 2.4GHz to 2.485GHz, and the electromagnetic intensity reaches -40dBmW when the gap breakdown voltage is about 15kv. The breakdown voltage at the substation site may be stronger, which ha...
