The invention relates to a monitoring system and method based on the industrial wireless network WIA-PA wireless communication standard. A RS232 interface and communication circuit and a USB interface and communication circuit are connected to a communication interface coexistence circuit so as to send a received signal to the communication interface coexistence circuit; the communication interface coexistence circuit is connected to a MCU through a communication interface switching circuit and an interface circuit so as to send the switched signal to the MCU to be controlled; the MCU is orderly connected with a radio frequency transceiver and a power amplifier; the other end of the power amplifier is connected with an antenna interface; a data storage unit is connected with the MCU to receive and store the data information sent by the MCU. The monitoring system disclosed by the invention can be used for WIA-PA communication channel monitoring and controlling so as to facilitate the field wireless communication status and the WIA-PA wireless equipment running status investigation; the WIA-PA wireless network communication planning is facilitated so that the project can be better implemented.
Description
technical field [0001] The invention relates to the field of industrial wireless network WIA-PA wireless communication, in particular to a monitoring system and method based on the industrial wireless network WIA-PA wireless communication standard. Background technique [0002] With the vigorous development of the Internet of Things in my country, the number of short-distance industrial wireless network WIA-PA wireless communication system equipment has greatly increased. In particular, the improvement of the industrial control system has gradually increased various WIA-PA wireless instruments and control equipment. [0003] However, when such wireless instruments and equipment are used in large quantities, and the wireless network of field equipment is in an unknown state, new wireless equipment will cause interference to existing equipment, or cause interference to new equipment, and it is easy to cause co-frequency interference and adjacent frequency interference, eventu...
