Common Problems & Solutions Of Lora Wireless Remote Water Meter In Use

With the development of low-power Wan Lora wireless communication technology, the market share of Lora wireless remote water meter is also increasing. Combined with the actual use, this paper expounds personal relevant views on the common problems and solutions in the use of Lora wireless remote water meter.


Key words: Lora wireless remote water meter


     In the process of using the wireless remote water meter, affected by the on-site environment, weather and local mobile network, different solutions are needed for different problems.


    1. The wireless remote water meter does not communicate for the following reasons:


    1) The wireless remote water meter is artificially damaged or completely shielded with metal, so that the wireless signal cannot be sent out;


    2) The battery in the water meter is under voltage, and the wireless remote transmission module cannot work normally;


    3) Failure of wireless acquisition equipment, such as power failure of concentrator, arrears of built-in flow card, falling or damage of equipment antenna;


    4) The routing path of wireless remote water meter is disordered, resulting in meter reading failure;


    In view of the above situations, the following methods can be used:


    1) Check the water meter on site and check whether the water meter is damaged or shielded with a metal cover;


    2) Through the background meter reading and early warning system, count and query the water meter with low battery voltage, and replace the new battery;


    3) Check the equipment on site for normal power supply, check whether the flow card is in arrears, and check whether the equipment downlink Lora antenna is      


    Whether it is damaged by others;


    4) Remotely read the routing path of the wireless remote water meter, and reset the meter reading path through the background software.






1. There are several reasons for non communication of wireless remote water meter during communication:


1) Check whether the battery in the meter has low voltage;


2) Whether the external environment is bad (such as thunderstorm weather, external strong electromagnetic interference, etc.);


3) The local mobile signal is unstable;


  In view of the above situations, the following methods can be used:


1) Require users to replace the battery in advance to improve the success rate of meter reading;


2) Set up a supplementary reading mechanism in the system to copy the failed meter for many times, so as to improve the overall success rate of meter reading;


3) Adopt high gain GPRS antenna, or extend the GPRS antenna to the place with strong outdoor mobile network signal.


4) You can also add routing nodes, use professional repeaters, or use wireless remote water meters as repeaters to improve the overall meter reading success rate.


Conclusion: the wireless remote transmission water meter is greatly affected by the external environment, such as the steel-concrete structure of the building, 470MHz ~ 510mhz power frequency signal, weather environment and other factors, so the consistency of the wireless remote transmission scheme is poor. We can only improve the performance of the meter end antenna, improve the anti-interference of the software system and adopt a reasonable wireless frequency hopping scheme, To improve the wireless performance and reliability of the whole meter.
