Description
Technical Field
The invention relates to the technical field, in particular to a system and a method for collecting power utilization information based on clock time service.
Background
The electricity consumption information acquisition device basically covers all public and special transformers and resident users on the urban power distribution network, and achieves full coverage and full acquisition. Along with the deepening of the function application of the acquisition system, some problems emerge continuously, for example, the success rate of meter reading in some places is low, the meter reading is unstable, GPRS communication is not available, the clock of the equipment is out of tolerance, and the like. Among these problems, especially the out-of-tolerance of the device clock, wide influence range and long span time are always a difficult point in the electric information acquisition device.
In the electricity consumption information acquisition device, an acquisition terminal acquires data from an electric energy meter, stores the data according to a certain format, generally stores the data according to time, and waits for a master station to read or actively report to a master station server. In this process, it is necessary that each layer of acquisition device has an accurate clock source, and the clock source is kept synchronous. After the field acquisition equipment is installed and debugged, the equipment runs for a period of time, and the clock sources of all layers of equipment are gradually found, so that great clock out-of-tolerance is generated, even the clock sources of some equipment are completely disordered, and great troubles are brought to the field acquisition function and the deepened application.
At present, for a distribution room with a clock out-of-tolerance fault, the traditional solution is to analyze the situation of daily data acquisition when the success rate of equipment acquisition is low, and screen out the equipment with the clock out-of-tolerance when the success rate of acquisition is reduced in a continuous period of time and the equipment is manually checked on site, wherein the solutions mainly include the following three methods:
(1) change collection terminal
The cost for replacing a new acquisition terminal is high, and huge manpower, material resources and financial resources also need to be consumed. More importantly, the disassembly and assembly of the electric meter can cause great inconvenience to electricity customers, possibly cause negative effects to state network companies, and generate public sentiment and complaints.
(2) Adopt infrared palm machine timing
The normal power consumption of the power consumption customer can not be influenced, but after the problem table needs to be found on the spot, the staff carries out point-to-point timing. Due to the wide distribution area of the acquisition terminals, the workload of checking the clock abnormal terminals is also very huge.
(3) Remote time correction of master station of power consumption information acquisition device
The acquisition terminal can carry out remote master station time synchronization by using the acquisition system, and if the time synchronization is unsuccessful, the acquisition terminal needs to adopt a common palm machine for time synchronization.
The traditional solution seriously has hysteresis in finding out the fault equipment and has low accuracy; when the fault equipment is processed, time and labor are wasted, and resources are wasted. As the number of faulty devices increases year by year, the traditional solutions are increasingly unable to meet the field use requirements.

A power utilization information acquisition method based on clock time service is characterized by comprising the following steps: the power consumption information-based acquisition device comprises the following steps that S1 acquires power-off information of an acquisition terminal, a controller of the acquisition terminal learns that the acquisition terminal loses power supply, and the controller of the acquisition terminal reads a first clock T1 from a clock chip of the acquisition terminal and stores the first clock T1 in a memory of the acquisition terminal; s2 detection of abnormal clock source of the acquisition terminal is carried out, the controller of the acquisition terminal learns that the acquisition terminal obtains power supply, the controller of the acquisition terminal reads a second clock T2 from a clock chip of the acquisition terminal and stores the second clock T2 in a storage of the acquisition terminal, the controller of the acquisition terminal judges whether the format of the second clock T2 is legal or not, and when the format of the second clock T2 is illegal, the controller of the acquisition terminal generates information of failure of the clock source of the acquisition terminal; s3 recovering the clock source of the acquisition terminal, acquiring the fault information of the clock source of the acquisition terminal by the controller of the acquisition terminal, acquiring correct clock information from the communication base station and writing the correct clock information into the clock chip of the acquisition terminal; in step S2, when the format of the second clock T2 is legal, the controller of the acquisition terminal compares the first clock T1 with the second clock T2, when the second clock T2 is smaller than the first clock T1, the controller of the acquisition terminal generates information about a failure of the clock source of the acquisition terminal, otherwise, the controller of the acquisition terminal acquires information about an actual power outage interval from the server, and when the value of the second clock T2 — the first clock T1 > the actual power outage interval, the controller of the acquisition terminal generates information about a failure of the clock source of the acquisition terminal.
6. The power consumption information acquisition method based on clock time service as claimed in claim 5, wherein: in step S3, the controller of the acquisition terminal acquires the correct clock from the communication base station using the AT command.
7. The clock time service-based power consumption information acquisition method according to claim 5, characterized in that: the acquisition terminal is connected to the communication base station through a communication device of the acquisition terminal, the communication base station is interconnected and communicated with each other to form a special internet used in a power supply department, the server is connected to the special internet through the communication device of the server, and the acquisition terminal is connected with the server through the special internet and is communicated with the server.
