3. the time synchronization message is defined as: defining effective contents of a time tick message as 15 segments of data, wherein each segment of data comprises 4-bit binary codes, defining contents of 1 st segment, 2 nd segment, 3 rd segment and 4 th segment from left to right as millisecond time, defining contents of 5 th segment and 6 th segment from left to right as seconds, defining contents of 7 th segment and 8 th segment from left to right as minutes, defining contents of 9 th segment and 10 th segment from left to right as hours, defining contents of 11 th segment and 12 th segment from left to right as dates, defining contents of 13 th segment from left to right as months, and defining contents of 14 th segment and 15 th segment from left to right as years, or defining in reverse order; for effectively transmitting data and resisting external interference, defining the time synchronization message tail as 4-segment binary code, and defining the rest segment as time synchronization message head; in the time setting process, the electric power payment machine identifies effective contents in the time setting message, and then converts each section of binary system in the time setting message into a decimal system, so that the time setting effect of electric power payment is realized;
4. splitting the time tick message, dividing 60 bits of 15 segments of contents into 10 equal parts, wherein each equal part contains 6-bit binary numbers;
5. the marketing department of the power supply company sets a self password for the maintenance personnel in the special power supply company, and the password consists of 8 or 10 decimal digits;
6. the password of the electric power payment machine is formed by a time setting message and the password of the personnel in the power supply company, wherein 1 in the password of the personnel in the power supply company corresponds to the first part in 10 equal parts, 2 corresponds to the second part in 10 equal parts, and the rest is repeated to form 8 parts or 10 parts, and the 8 parts or 10 parts are defined as the password section combination of the electric power payment machine.
7. And converting the binary system of each equal part in the code section combination of the electric power payment machine into a decimal system, and defining the finally formed decimal system code as an unlocking code of the electric power payment machine.
Further, the header and the trailer of the message are displayed in hexadecimal.
The invention has the beneficial effects that:
because the GPS time tick message not only contains instantaneous change data such as millisecond, second and the like, but also contains infrequent change data such as year, month and day and the like, binary systems of the two data are rearranged, and then the binary systems are matched with self passwords of personnel in a power supply company for arrangement and guidance, so that the unlocking passwords of the electric power payment machine can follow irregularly, the operation authority of the electric power payment machine is greatly improved, and the loss of an electric power system is avoided.
The invention can be applied to an electric power system, is also suitable for other unattended payment platforms, and has wide popularization.
