Description

Electricity consumption information collection system and method based on clock timing

technical field

The invention relates to the technical field, in particular to a system and method for collecting electricity consumption information based on clock timing.

Background technique

The electricity consumption information collection device basically covers all public transformers, special transformers and residential users on the urban distribution network, achieving full coverage and full collection. With the deepening of the application of the functions of the acquisition system, some problems have emerged one after another, such as the low success rate of meter reading in some places, the unstable meter reading, the failure of GPRS communication, and the out-of-tolerance equipment clock. Among these problems, especially the equipment clock is out of tolerance, the influence range is wide, and the spanning time is long, which has always been a difficulty in the power consumption information collection device.

In the electricity consumption information collection device, the collection terminal collects data from the electric energy meter, and stores and processes the data according to a certain format, generally according to the time, and then waits for the master station to read or actively report to the master station server. In this process, each layer of acquisition equipment needs to have an accurate clock source and keep the clock source synchronized. After the on-site acquisition equipment is installed and debugged, after a period of operation, it is gradually found that there is a large clock difference between the clock sources of the equipment at each layer, and even the clock sources of some equipment are completely disordered, which greatly improves the on-site acquisition function and deepens. The application brought a lot of trouble.

At present, for stations with clock out-of-tolerance faults, the traditional solution is to analyze the situation of daily data collection when the equipment acquisition success rate is low. There are three main solutions to screen out the devices with clock out-of-tolerance:

(1) Replace the acquisition terminal

Replacing a new collection terminal is expensive, and it also requires huge human, material and financial resources. More importantly, dismantling and assembling electricity meters will cause huge inconvenience to electricity customers, and it is likely to have a negative impact on State Grid Corporation, resulting in public opinion and complaints.

(2) Using infrared handheld computer to adjust the time

It will not affect the normal electricity consumption of electricity customers, but after finding the problem table on site, the staff will check the time point-to-point. Because the collection terminals are widely distributed, the workload of checking the abnormal clock terminals is also huge.

(3) Remote time calibration of the main station of the electricity information collection device

The acquisition terminal can use the acquisition system to perform time synchronization with the remote master station. If the time synchronization is unsuccessful, a common handheld computer is required to synchronize the time.

The traditional solution has a serious lag in the detection of faulty equipment, and the accuracy rate is low; when dealing with faulty equipment, it is time-consuming, labor-intensive, and a waste of resources. As the number of faulty equipment increases year by year, traditional solutions are increasingly unable to meet the needs of on-site use.

The idea of this application:

The system includes a power consumption information collection device, a module for obtaining power-off information of the collection terminal, a detection module for an abnormal clock source of the collection terminal, and a clock source recovery module for the collection terminal; the method includes S1 that the controller of the collection terminal learns that the collection terminal is powered off, and obtains the power from the collection terminal from the clock of the collection terminal. The first clock T1 is read in the chip and stored, and the controller of the S2 collection terminal knows that the collection terminal is powered, and reads the second clock T2 from the clock chip of the collection terminal.

The recovery module, etc., realizes the correction of the clock of the acquisition terminal.

Improvement ideas:

In the case of not replacing equipment and correcting the time on site, the acquisition terminal finds the fault of its own clock source in time and automatically corrects the wrong clock, which has become the research direction. By analyzing the causes of the over-tolerance of the equipment clock in the system, a clock timing scheme based on the system itself is found without additional modification of the system equipment, which provides a reference for solving the problem of the over-tolerance of the on-site clock.

The GPRS network in the communication channel layer provides us with a new idea. The use of the GPRS network will inevitably use the mobile network base station, and the GPRS module on the acquisition terminal can obtain the clock from the mobile network base station, which provides support for obtaining the correct clock source. More than 95% of the on-site acquisition terminals use the GPRS network, so a timing scheme based on the GPRS network is proposed.

Technical solution description:

The timing scheme based on GPRS network is divided into two aspects: abnormal clock source detection and abnormal clock source recovery.

1. Abnormal clock source detection of the acquisition terminal

01 When the acquisition terminal is powered off, read the clock in the clock chip and record the clock as T1.

02 After the acquisition terminal is powered on, read the clock T2 in the clock chip. Determine whether the format of the clock T2 is legal. If the format of the clock T2 is illegal, it can be concluded that the clock source of the acquisition terminal is faulty and directly enter the abnormal clock recovery process of the acquisition terminal; if the clock T2 is legal, continue with the following judgment process.

03 Determine the values of the system clocks T1 and T2. If T2 is less than T1, or the value of T2-T1 is greater than the actual power failure interval, it also indicates that the clock source of the acquisition terminal is faulty, and the abnormal clock recovery process of the acquisition terminal is entered.

2. Abnormal clock source recovery of the acquisition terminal

After the acquisition terminal detects the failure of the clock source, it obtains the correct clock from the mobile network base station through the terminal's own GPRS module and uses AT commands, and writes the clock into its own clock chip.

Until the acquisition terminal is powered off again, the clock in the acquisition terminal will remain correct. Even if the terminal is powered off again, the acquisition terminal can still repeat this process after power-on to ensure that the internal clock source of the acquisition terminal is correct.

After the application has been run confidentially for a period of time, the benefits of feedback from on-site technicians are:

The clock timing scheme based on the power consumption information acquisition device has been promoted, and it does not require additional modification of the field equipment, which will save a lot of manpower, material resources, and financial resources, and at the same time improve the acquisition success rate. It is an ideal solution to the problem of field equipment clock out of tolerance.

The clock timing solution can automatically identify the out-of-tolerance station area and automatically complete the clock calibration without manual intervention in the whole process, avoiding the waste of human resources caused by manual background detection and manual on-site time calibration, and saving 350,000 yuan.

It solves the serious lag in the detection of faulty equipment in the traditional solution, greatly improves work efficiency, and improves the accuracy of school time by 90%.

There is no need to renovate on-site equipment, which will greatly reduce the number of terminal equipment replacements and save 1.85 million yuan in renovation funds.

The automatic clock is completed in a non-power-off mode with zero user perception, and customer complaints caused by replacing the acquisition terminal are reduced to 0.

The problem of acquisition failure caused by clock errors is effectively solved, which provides technical support for improving the acquisition success rate of the terminal.

Through this innovation, a method for improving the success rate of electricity consumption information collection based on clock timing is studied. This timing method has high efficiency and high accuracy, improves quality and efficiency, saves costs, and improves the company's competitiveness.
