Recently, there are often users consulting, radar level meter data jumping in the process of what is the cause, and how to solve? Today, I will give you an introduction.
In the process of transmitting radar waves, reflecting radar waves, and receiving radar waves, the technical index of the radar level meter itself determines the signal quality of the transmitting and receiving process, while various interference factors will make the reflected wave signal strength decrease, and the reflected wave received by the radar level meter is too weak or cannot receive the reflected wave, resulting in data jump.
What exactly should I do to solve this situation? First of all, switch to a normal power supply to ensure stable working conditions. In order to better ensure the power consumption of the system, the RTU will control the power supply of the radar level meter, and the general data acquisition frequency is set to not less than 6 minutes.
During the interval between data acquisition and transmission, the RTU will stop supplying power to the radar level meter and the RTU itself will go into a sleep state to reduce power consumption. In the next data acquisition cycle, the RTU will automatically wake up and supply power to the radar level meter.
After the radar level meter is powered on and warmed up for tens of seconds, the RTU sends data acquisition commands to it, acquires the return data, and sends it.
Secondly, increase the transmission power and signal reflection, because the strength of the reflected wave determines the success or failure of the measurement, different interference has different effects, we can increase the transmission power to 70m range, then there will be no data jump, in short, the appropriate increase in transmission power can effectively reduce the probability of data jump.
The final filtering of jump data for multiple average measurements is done to better handle data jumps in special cases, and the software program cured in the CPU of the radar level meter is optimized so that jump data can be avoided to a greater extent.
The original data processing of the software program cured in the CPU is such that after transmitting a pulse wave and receiving a reflected wave, a set of data is quickly processed and sent back to the RTU as measurement data, so it is easy to treat the jump data as normal data. By adjusting the normal power operation mode, the radar level meter is in a stable operating condition.
