1.3 the automobile sensor sends the specially changed secret key and the random number to the taximeter together;
and 1.4, the taximeter re-encrypts the specially changed secret key according to the random number to generate a second encryption matching code.
Step 2: the taximeter process judges whether the taximeter is cheated or not, and comprises the following specific steps:

2.2 the taximeter determines whether the data packets of the continuous sensor encryption pulses received before and after are the same, if so, the taximeter discards the data packets without counting, thereby avoiding the cheating behavior of copying the pulse mode.
And 2.3, the taximeter decrypts the encrypted pulse data packet according to the second encrypted matching code and the random number, determines whether the serial number is legal and continuous, and judges that the sensor equipment is abnormal or suspected to cheat if the serial number is illegal or discontinuous. The data in the encrypted pulse data packet contains a certain number, and whether the data is legal or not is judged through the continuity of the number.
