1. Basic situation analysis
Before the use of meter reading machine, the water supply company used manual meter reading and card meter reading, with obvious disadvantages: for example, the handwriting is not clear when manually reading water, and it is easy to make mistakes when copying data to PC; The meter reader does not go to the site but only reads meters, and cannot read meters on the site; Meter readers are easy to "copy human water" because they seldom copy or do not copy water from users they are familiar with. Manual meter reading is inefficient. In the links of query, record and transmission, manual operation greatly reduces the working efficiency. Therefore, the company began to look for more effective meter reading solutions. The application of meter reading machine based on water supply sales management information system plays an important role in water meter location query, water volume data acquisition, transmission and processing, which is more cost-effective than centralized remote meter reading transmission. Among many meter reading schemes, this scheme is more suitable for the actual needs of water supply companies. Therefore, the company chose the meter reading scheme based on the data acquisition of the hand-held meter reading machine provided by Tongchuang Technology.
Application of meter reading machine in meter reading management
The application of water meter in water management of water supply company fully reflects the application value of water meter in data acquisition, transmission and other application links. The application of Tongchuang's meter reading machine system in the company actually represents the mainstream application mode of domestic meter reading machines. The application of meter reading machine in the company is introduced in detail.
2.1 Query location
Water charge software
When the water meter readers reach the previous performance field, they first query and locate the current user's water meter to determine the user's ownership of the water meter. Meter readers waste a lot of time and energy searching for the corresponding meter number, user number, water meter code and other information in the thick meter reading card; The next step is to determine that the user of a table such as "1001" belongs to "Zhang San".
The application of meter reading machine greatly shortens this tedious process. Tongchuang Technology provides three positioning methods:
Type query method: open the program menu of meter reading machine, enter meter number or user number "1001" through keyboard, and all information about the current water meter is reflected, including user name, water meter diameter, water of last month, current water, and no copy result.
Barcode query mode: considering the light and shade contrast, distance and distance of meter reading environment, and the inconvenience of meter reading personnel reading the water meter number, the system supports the query mode of laser reading barcode; This method needs to paste a certain length of bar code on the water meter. The bar code information mainly includes the number of meters, the number of users and other characters, numbers, and other types of content in the water meter reading staff. Only a simple bar code scanning operation button is required to complete the preliminary water meter positioning operation from the meter reading machine of the database with the customer information (for example, "sheets") of the information contained in the bar code (such as "1001").
The default method of meter reading sequence: the marketing system is equipped with the function of water adjustment meter serial number. The layout of meters is based on the adjacent water meter cards (or lists, meters, meter reading order, data administrator entrance, meter reading data download to the meter reading machine, and the automatic meter reading machine is based on the meter reading, according to the displayed serial number or adjacent water meters.
Through keyboard type, bar code type and preset meter reading order, the process of card information query and confirmation by meter readers is reduced, the work intensity of meter readers is greatly reduced, and the query speed is increased by dozens of times.
