[Meter's Latest Patent] A Household Dispersed Multi-Table Acquisition System Installation Method

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we will introduce a national invention-authorized patent – ​​a method for installing a multi-meter acquisition system with a decentralized household. The patent was applied by State Grid Shanghai Electric Power Co., Ltd., and it was authorized on December 29, 2017.

Content Description

The invention relates to the field of data acquisition technology, and in particular to a method for installing a multi-meter acquisition system with a decentralized household.

Background of the invention

Traditional data collection of water meters, electricity meters, and gas meters is based on manual data collection by the people. This makes data collection time-consuming and time-consuming and difficult to guarantee accuracy and timeliness. It inevitably has the following problems: There are errors in the data, and it is impossible to truly reflect users' water, electricity, and gas conditions, and the operation is difficult to standardize, resulting in an increase in unclear losses; it is labor-intensive, costly, and inefficient. With the development of society, the increase of users and the further implementation of one-for-one work, the meter reading workload of power, water, gas and other residents has increased significantly, while the retail houses and villas are generally distributed in a wide range, to meter reading personnel. This has brought a lot of inconvenience, which urgently requires the use of modern technology to solve the problems encountered in the meter reading work and improve the management level of electricity, water, and gas.

Summary of the Invention

The purpose of the present invention is to provide a method for installing a multi-table acquisition system with a decentralized householder in order to overcome the deficiencies of the prior art mentioned above.

The Figure is a flowchart of the method of the present invention.

The purpose of the present invention can be achieved through the following technical solutions: A method for installing a multi-meter acquisition system with a decentralized household includes the following steps: S1. Installing a concentrator: According to the type of the substation in the station area, the concentrator is installed in the substation of the station area. Inner side, outer side or next to the nearest main fuse box of the station substation; S2, installation of collector and protocol converter: If there are not less than 2 meter boxes within a diameter of 20 meters, the collector and protocol converter are installed In or around one of the appropriate meter boxes, otherwise, each meter box is equipped with a collector or protocol converter. The power cords of the collector and protocol converter are connected to the lower terminal of the main power supply in the meter box through the connection terminals. Head; S3, communication connection: The concentrator is connected to the collector or protocol converter through the RS485 bus or power line carrier. Each meter is connected to the collector or concentrator through the RS485 bus, and the various water meters and gas meters are collected through the M-Bus bus connection. Or protocol converters.

In step S1, the station power station types include: PT type substations, KT type substations, box type substations, and pole frame type stations. Step S1 specifically includes: when the station substation is a PT or KT substation, if there is a fiber channel or GPRS wireless public network signal in the station, the concentrator is installed on the wall of the low voltage room in the station, otherwise the concentrator is installed closest to the transformer. Beside the total fuse box; if the substation in the station area is a box-type substation, if there is an installation position inside the substation, the concentrator is installed in the box-change low-voltage bin, otherwise the concentrator should be installed outside the box or be closest to the transformer. Next to the wire box; when the power supply in the station area is a pole-mounted station, the concentrator is installed next to the main fuse box closest to the transformer. The meter box in a suitable position in step S2 is specifically a distance and a minimum meter box within a diameter of 20 meters to all meters. In step S1, the operating power of the concentrator installed inside or outside the substation is taken from the busbar on the low side of the corresponding transformer, and the working power of the concentrator installed next to the main fuse box is connected to the pile head of the main fuse box. The sum of the number of energy meters and protocol converters connected to each RS485 port of the collector is not more than 32, and the number of each connected water meter or gas meter of the protocol converter is not more than 16. The M-Bus bus uses a 1mm2 2-core twisted pair cable.

Compared with the prior art, the collector and the protocol converter of the present invention adopt a wired communication method to communicate with the meter, the channel is stable and reliable, and the collection success rate is high, thereby realizing the unified collection and management of electricity, water, and gas data of the decentralized house, and saving Manpower has improved the management of electricity, water, and gas.
