Abstract

The invention discloses a wireless binary channel detection device, comprising a GPRS wireless communication module (5), a CDMA wireless communication module (6), an antenna, a SIM card, and a power supply circuit (10) which are interconnected. The wireless binary channel detection device is characterized in that the GPRS wireless communication module (5) and the CDMA wireless communication module (6) are connected to a simulation channel switching circuit (7); the simulation channel switching circuit (7) comprises a signal processing 89C2051 circuit (7-1)and a relay or a simulation electronic switch (7-2); the signal processing 89C2051 circuit (7-1) is connected to the GPRS wireless communication module (5) and the CDMA wireless communication module (6);and the relay or the simulation electronic switch (7-2) is connected to the RS232 conversion circuit (8) and the RS485 conversion circuit (9) which are connected to the external ports. The wireless binary channel detection device is stable in operation, improves the access rate of the wireless network, saves the investment, effectively shortens the outage time, provides a safe channel environment to the operation of the distribution network and supports the dual-network simultaneous operation.

Description

Technical field: [0001] The invention relates to a wireless dual-channel intelligent detection device, which belongs to the field of power distribution operation of a power system. Background technique: [0002] As the urban population increases, the urban area expands. There are more and more power distribution FTUs and DTUs, and the maintenance workload is also increasing. At present, the communication mode of power distribution terminals mainly adopts wireless 2G network, and optical fiber communication is used in some cases. Due to the high cost of using fiber optic channels and the low utilization rate of fiber optics, 90% of the channels of distribution network terminals still use wireless communication. Because the wireless channel communication is not stable, sometimes the signal is strong, sometimes the signal is weak, sometimes the signal of China Unicom is strong, and the signal of China Mobile is weak, and at other times the signal of China Unicom is weak, and ...
