Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power automation technology, and specifically to an HPLC intelligent meter data transmission optimization and encryption system and method. Background Art
[0002] The data transmission of HPLC intelligent meters is achieved through power line communication (PLC) technology. Specifically, HPLC intelligent meters use power lines as a communication medium and combine high-speed carrier technology to achieve remote data transmission, thereby completing remote meter reading by the circuit department. This process not only improves the efficiency and accuracy of meter reading but also greatly reduces labor costs. It also has the advantages of high efficiency, reliability, and real-time performance.
[0003] Although the existing data transmission of HPLC intelligent meters meets the data transmission requirements to a certain extent, due to the limitations of the application structure and implemented functions, there are still the following technical drawbacks. First: HPLC intelligent meters in different regions usually transmit data in real time (in fact, at the far end, it is not necessary to obtain the usage data at the meter in real time, etc.). This will bring a problem that the bandwidth of the power line for sending data is limited, and the power consumption data sent by different HPLC intelligent meters at the same time is prone to interference with each other and signal attenuation, resulting in deviations in the received power consumption data analysis by the relevant circuits and software at the receiving end, which may cause unnecessary economic losses to the power users and power suppliers (for example, over-measurement of power consumption will cause losses to the power users, and under-measurement of power consumption will cause losses to the power suppliers). Second: When sending power consumption data, HPLC intelligent meters in different regions all work at the same frequency (or HPLC intelligent meters in a corresponding location work at one frequency, and those in other locations work at another frequency). In this way, it is impossible to prevent other people or resistors from illegally receiving or destroying the data, which will have an adverse impact on safe power supply and correct power consumption billing. Considering the above factors, it is very necessary to provide an intelligent meter data transmission optimization and encryption method that can reduce the data sending frequency and prevent illegal reception or destruction of data transmission.

This computer software product is stored in a storage medium and includes several instructions to enable a computer device (which may be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the methods described in various embodiments of the present invention. The aforementioned storage medium includes: various media that can store program codes, such as USB flash drives, mobile hard disks, read-only memories (ROM, Read-Only Memory), random access memories (RAM, Random Access Memory), magnetic disks, or optical discs.

For the purposes of this specification, a "computer-readable medium" can be any device that can contain, store, communicate, propagate, or transport a program for use by or in combination with an instruction execution system, apparatus, or device.

[0072] It should be understood that each part of the present invention can be implemented by hardware, software, firmware, or a combination thereof.

[0073] Embodiment 3 provides a method for optimizing and encrypting data transmission of HPLC smart meters:
[0074] The first timing module outputs a certain time signal to the signal input end of the first data transceiver module at regular intervals (for example, in the daily time, a 5 - second time signal is output every 30 minutes; there is an interval in the time for all HPLC smart meter data transmissions), and the first data transceiver module transmits the timing signal wirelessly.
[0075] The second timing module outputs a certain time signal to the signal input end of the second data transceiver module at regular intervals (for example, in the daily time, a 5 - second time signal is output every 30 minutes). The second data transceiver module wirelessly receives the timing data signal transmitted by the second data transceiver module, and then outputs the signal to the second control module. The analysis unit of the second control module compares the time signal transmitted by the second data transceiver module with the time signal output by the second timing module. When the two time signals are exactly the same, the second control module controls the second data transceiver module to wirelessly send out a signal indicating that the time comparison is consistent. At the same time, the second control module outputs a signal to enable the second output module to output power for a certain time to the data processing module, and the data processing module gets powered on to work.
[0076] The first data transceiver module receives the time-consistent signal sent by the second data transceiver module. After the analysis unit of the first control module analyzes the data, it controls the first output module to output power for a certain period of time to the data transmission module. The control unit of the data transmission module controls the HPLC smart meter data transmission module to output compressed power consumption data signals and other signals to be electrically transmitted through the power line. Specifically, after the first data transceiver module receives the time-consistent signal sent by the second data transceiver module, when the times of the first timing module and the second timing module are inconsistent, the first control module can automatically adjust the timing time of the timing module so that the current times of the first timing module and the second timing module are consistent. During data transmission by the data transmission module, the multi-channel high-level signal output terminals 3, 4, 5, 6, 7, 8, 9, and 10 of the first encoding sub-module will be respectively connected to the multi-channel signal input terminals 3, 4, 5, 6, 7, 8, 9, and 10 of the first signal conversion sub-module. In this way, after one or more high-level signal output terminals of the first encoding sub-module are connected to one or more signal input terminals of the first signal conversion sub-module, the first signal conversion sub-module can perform different encodings on the power consumption data and other data input by the HPLC smart meter data transmission module and send them out.
[0077] After the data processing module receives data such as power consumption output by the HPLC smart meter data transmission module through the power line, the control unit processes the data and outputs it to the signal input terminal of the PC of the power management department. The PC displays data such as power consumption in the corresponding area in real time. Specifically, during data reception by the data processing module, the multi-channel high-level signal output terminals 3, 4, 5, 6, 7, 8, 9, and 10 of the second encoding sub-module will be respectively connected to the multi-channel signal input terminals 3, 4, 5, 6, 7, 8, 9, and 10 of the second signal conversion sub-module. In this way, after one or more high-level signal output terminals of the second encoding sub-module are connected to one or more signal input terminals of the second signal conversion sub-module, the second signal conversion sub-module can decode and receive the encoded power consumption data input by the HPLC smart meter data transmission module.
[0078] Figure 1 , 2As shown in FIGS. 1 and 3, through the above, under the combined action of the relevant circuits and software units, the present invention can control the on-site HPLC intelligent electric meter to send the corresponding compressed data at regular intervals, and the HPLC intelligent electric meters in different regions send power consumption data (including data such as temperature, current, and voltage), preventing the problems of uninterrupted data sending, interference caused by different HPLC intelligent electric meters when sending data, and relatively low transmission rate. Moreover, the password circuit can automatically and dynamically synchronously change the password data of the data processing module at the receiving end and the data transmission module at the sending end every time data is sent and received. Since data is sent and received through dynamic coding changes, the probability of illegal reception or damage during the data sending of the HPLC intelligent electric meter is reduced, providing strong technical support for the effective and secure data transmission of the HPLC intelligent electric meter.
