specific Embodiment

[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...

Abstract

The invention discloses an electric meter calibration method based on blue-tooth transmission, and belongs to the technical field of power equipment. An existing Bluetooth interface, just like all other wireless module interfaces, has the problem that data cannot be completely received, that is, the signal-loss may be present in the electrical pulse conversion process, thereby affecting the calibration accuracy. Through continuous exploration and tests, the present invention provides a calibration method for multiple retransmission signals, the existing calibration mechanism of single signal transmission and receiving is broken through, the concept is skillful, and the scheme is feasible. According to the electric meter calibration method based on blue-tooth transmission disclosed by the invention, a converted blue-tooth signal of a calibrated meter is retransmitted to calibration equipment in multiple times, the packet loss rate of the wireless signal can be effectively reduced and the reliability of reception can be improved. The calibration equipment in the present invention recognizes an effective error detection start point and an effective error detection end point; as long as a signal in the middle process is received by the effective data packet once, the calibration equipment can record the correct number of pulses and can effectively improve the calibration efficiencyand accuracy.

Description

technical field [0001] The invention relates to an electric meter verification method based on bluetooth transmission, which belongs to the technical field of electric equipment.
