Example one
As shown in fig. 1, a circuit signal processing method according to a first embodiment of the present invention includes the following steps:
step 1: setting a plurality of circuit signal threshold values, wherein a plurality of circuit signal range values with the same interval size are formed among the circuit signal threshold values. Specifically, for example, circuit signal thresholds of 10mV, 20mV, 30mV, and 40mV are set, and these circuit signal thresholds constitute circuit signal range values of 10mV to 20mV, 20mV to 30mV, and 30mV to 40mV, respectively.
Step 2: comparing the size value of the circuit signal with a plurality of circuit signal range values, if the circuit signal is within the circuit signal range value set in the step 1, obtaining a target circuit signal range value in which the circuit signal falls, and executing the step 3, if the circuit signal is smaller than a set minimum circuit signal threshold value, taking the minimum circuit signal threshold value as the target circuit signal. Specifically, for example, if the value of the collected circuit signal is 24mV, and the value is within the circuit signal range set in step 1, step 3 is executed; if the value of the collected circuit signal is 5mV or 45mV, the circuit signal with the value of 10mV or 40mV is used as the target circuit signal.

Specifically, for example, the value of the acquired circuit signal is 24mV, 0mV, 10mV, 20mV, 30mV, and 40mV are set as a plurality of adjustment steps, when the signal adjustment step of the receiver is set to 10mV, 14mV is obtained by subtracting 10mV from the acquired circuit signal 24mV, and the circuit signal with the size of 14mV is used as the target circuit signal if 14mV is greater than 10 mV; when the signal adjustment gear of the receiver is set to 20mV, the acquired circuit signal 24mV is subtracted by 20mV to obtain 4mV as the processed circuit signal, and 4mV is less than 10mV, so that the set minimum circuit signal threshold value of 10mV is used as the target circuit signal.

The purpose of the above arrangement is: for example, when the receiver is far away from the pipe blockage point, the signal received by the receiver is very weak, and a minimum first target circuit signal threshold value is set to be convenient for checking whether the first response module of the receiver works normally or not based on the purpose of the second signal processing module. When the receiver is closer to the pipeline blockage point, the received circuit signal is stronger. On one hand, the excessive sound gives people a feeling of noise, which can cause discomfort of the human body, on the other hand, when the intensity of the sound exceeds a certain limit, the sensitivity of the human ear to the sound is weakened, and in addition, the first response module and the second response module are arranged to form a comparison, so that the superiority of the product of the invention relative to a common receiver can be more intuitively and obviously highlighted.
