The solution for the non-communication when the photoelectric direct reading remote water meter
In view of the above situation, it can be dealt with in the following ways:
.Treat loose and oxidized contacts and replace aging circuits;
.Set up a supplementary copy mechanism in the system to copy the failed meters for many times to improve the overall success rate of meter reading;
.The selection of the communication bus is strictly controlled, and the number of bus load meters is less than the single load of the equipment;
.Use a high-gain GPRS antenna, or extend the GPRS antenna to a place with strong outdoor mobile network signals.
The photoelectric direct reading remote water meter is greatly affected by the quality of the bus. The use of wireless communication between the collector and the concentrator is susceptible to factors such as the steel-concrete structure of the building, the 433Mhz public frequency band, and the weather environment. Therefore, during the construction and debugging process, certain It is necessary to strictly control the communication line specifications and wiring quality, and lead the collector and concentrator antennas to an open location as much as possible; at the same time, improve the anti-interference of the software system to improve the meter reading success rate and stability of the photoelectric direct reading remote water meter.
