[0084] The starting point of the error detection is that when the measurement error is started, the verification device detects a complete wireless retransmission data packet;
[0085] The end point of the error detection is when the error measurement ends, the verification device detects a complete wireless retransmission data packet.
[0086] Regardless of whether the intermediate pulse receives a complete wireless retransmission signal during the verification process, it is necessary to ensure that the complete wireless retransmission data packet is detected when the measurement error is started, and the complete wireless retransmission data packet is also detected when the verification process of a load point is completed. wireless retransmission packets. As for the signal in the intermediate process, as long as a valid data packet is received once, the verification equipment can record the correct number of pulses, which can effectively improve the verification efficiency...

The invention discloses an electric meter verification method based on bluetooth transmission, and belongs to the technical field of electric power equipment. The existing Bluetooth interface, like all other wireless module interfaces, has the problem that the data cannot be received 100% completely, that is, during the electrical pulse conversion process, there may be signal loss, which affects the verification accuracy. After continuous exploration and experimentation, the present invention provides a verification method for retransmitting signals for many times, breaks the existing verification mechanism of single sending and single receiving of signals, is cleverly conceived, and has a feasible solution. The inspected meter of the present invention retransmits the converted bluetooth signal to the inspection equipment for many times, which can effectively reduce the packet loss rate of the wireless signal and improve the reliability of reception. The verification device of the present invention identifies the effective error detection start point and the effective error detection end point, and the verification device can record the correct number of pulses as long as the signal in the intermediate process is received once a valid data packet is received, thereby effectively improving the verification process. Efficiency and Precision.
Description
