[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national patent for invention—collector for centralized meter reading system and method for collecting and managing the asset number of electric meters. The patent was applied for by Shenzhen Kelu Electronic Technology Co., Ltd. and obtained the authorization announcement on November 28, 2017.
Content Description
The invention relates to a centralized meter reading system, in particular to a collector and meter asset number collection management method.
Background of the invention
In the process of building a smart grid, in order to enhance the two-way interaction between the grid and users and the value-added services, the size of the power information collection system is getting larger and larger, and the centralized meter reading system is being used more and more widely. System maintenance work The volume is getting bigger and bigger, the maintenance cost is also getting bigger and bigger, the maintenance problem has already more and more constrained the operation effect of the entire centralized meter reading. The current concentrator completely relies on the parameters sent by the master station to measure points, directly collects the meter data, the collector relays the instructions of the concentrator, forwards the response of the next meter, and obtains the connected meter address under the answer of the meter. . In the concentrator
If you configure the information of the collector, you can easily understand the composition of the system, but the amount of engineering is huge, the cost is high, the management is confusing, and it is also easy to make mistakes. At present, it is also moving in the direction of not collecting information from the collector. If you do not configure the collector information, the collector is an invisible cassette for the concentrator. Once a collector fails, it will be impossible to find the collector. This makes maintenance difficult.
The disadvantages are: once the local area adjustment, collector or meter replacement, collector failure, etc., must go to the scene to confirm the relevant information, and then return to the main station to reissue the parameters, which leads to a low degree of intelligence, maintenance personnel need Running around to find the collector and concentrator installation points, the work efficiency is quite low.
Summary of the Invention
The technical problem to be solved by the present invention is to provide a centralized meter reading system collector and an electric meter asset number collection management method, which brings benefits for the efficient operation, maintenance management, and system monitoring of the system.
The picture shows the overall framework of centralized meter reading system
As shown, a centralized meter reading system collector and meter asset number collection management method includes a master station, a concentrator, a carrier table, a collector, and an electricity meter; and the master station is connected with a concentrator. In communication, the concentrator communicates with the carrier table and the collector, the collector connects with the meter, and the collector and meter asset number collection management method includes the following steps: (1) The concentrator collects data periodically every day. The receiver sends the command of the broadcast collector and the meter asset number; (2) After the collector receives the broadcast, it starts to search for the asset number of the meter; (3) After the concentrator waits for M minutes, M>5, and then sends the report to the collector. (4) The collector reports its own asset number and the asset number of the electricity meter hung under the collector to the concentrator; (5) The concentrator updates the electricity meter and its corresponding acquisition according to the collector's report. (6) The concentrator reports the asset number of the collector and the meter to the master station; (7) The master plots the assets of the meter reading system based on the relationship of the concentrator, collector, and meter. No management topology diagram.
As an improvement, the collector has a table for recording the asset number of the meter, a meter information mark that is found this time, a new meter information flag, and a valid meter information record mark, which initializes the data of the table and The flag is zero.
The invention realizes the collection and management function of the meter asset number of the centralized meter reading system collector, and provides a very convenient maintenance means for the failure or replacement of the collector or the carrier table, thereby reducing the workload of the staff of the meter reading system maintenance system. At the same time, in the process of collecting the asset number of the collector's electricity meter, the collector and the carrier table can work normally, which has little effect on the meter reading.

Car Air Purifier
The car purifier is also called a car purifier or a car Air Purifier, which usually consists of a high-voltage generating circuit negative ion generator, a micro fan, an air filter and other systems. Its working principle is as follows: the micro-fan (also known as ventilator) in the machine circulates the air in the car, and the polluted air passes through the PM2.5 filter and activated carbon filter in the machine to filter or adsorb various pollutants, and then After the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), the air is continuously ionized to generate a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
