Problems solved by technology
However, this measure is not conducive to the timely reading of the meter data by the power collection terminal. After the power collection terminal is powered on again, its important time-related functions such as data storage and task reporting are prone to confusion, resulting in the power collection terminal not operating normally.

Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0043] This embodiment provides a time setting method for a power collection terminal with an abnormal battery. The power collection terminal is a concentrator, and the battery in the concentrator is a normal rechargeable battery. Such as figure 1 As shown, the concentrator time synchronization method for battery abnormality in this embodiment includes the following steps:
[0044] Step 1, start the concentrator and make the concentrator in the running state;
[0045] Step 2, write the time of the concentrator into the ferroelectric of the concentrator according to the preset writing time interval; wherein, the preset writing time interval here is 1min;
[0046] Step 3, power off the concentrator, and then power on the concentrator;
[0047]Step 4, presetting the preset voltage threshold for abnormal battery voltage in the concentrator; for...

The invention relates to a time synchronization method for a power acquisition terminal with an abnormal battery, and the method comprises the steps: respectively judging a battery voltage abnormal condition and a time abnormal condition of the power acquisition terminal, and enabling the power acquisition terminal to carry out the processing according to the collected time of each electric meter.Therefore, different updating modes for the time of the electric power acquisition terminal are adopted according to the difference between the time of each ammeter and the time of the electric poweracquisition terminal, the time of the electric power acquisition terminal after updating time synchronization is accurate, self-repairing is realized, adverse effects on normal operation of the electric power acquisition terminal due to abnormal batteries are avoided. Normal work of the electric power acquisition terminal and important functions related to time is ensured, and normal reading of electric meter data by the electric power acquisition terminal is maintained.
Description
technical field [0001] The invention relates to the field of electric power, in particular to a time setting method for a power collection terminal with an abnormal battery. Background technique [0002] The development of my country's smart meter industry is relatively mature. According to statistics, the State Grid has accumulatively required 204.7 million smart meters, with an average annual demand of 40.94 million. The current operating power collection terminals have reached more than 1 million. In the future, the growth rate of the smart meter market will remain at around 15%. Power collection terminals are mostly installed in residential areas, and the installation locations are relatively concentrated. When there is a large area of failure in the power collection terminal, it will have a great impact on the lives of residents. Therefore, it is of great significance to improve the operation and maintenance efficiency of power collection terminals, solve problems i...
