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 is low in some places, 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 clock of the device, wide influence range and long crossing 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, each layer of acquisition device needs to have an accurate clock source, and keep the clock sources synchronized. After the on-site acquisition equipment is installed and debugged, after a period of time, the clock sources of all layers of equipment are gradually found to generate large clock out-of-tolerance, even the clock sources of some equipment are completely disordered, and therefore, the on-site acquisition function and the deepened application are greatly disturbed.
At present, for a station area 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 equipment acquisition is reduced continuously for a period of time and the equipment is manually checked on site, and the solution mainly comprises 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) Time correction by infrared palm machine
The normal electricity utilization of the electricity utilization client can not be influenced, but after a problem table needs to be found on the site, a worker conducts 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.
