1 Basic situation analysis

Before using the meter reading machine, the water supply company used manual and card reading methods, which had obvious shortcomings: for example, the handwriting was unclear when manually copying water volume, and errors were prone to occur when transcribing data into a PC; The meter reading personnel will only estimate and read the meter when they are not on site, and they cannot read the meter in place; Meter reading personnel seldom copy or do not copy the water volume of familiar users, which is easy to cause "human favor water"; The efficiency of manual meter reading is low. In the aspects 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 marketing management information system plays a huge role in water meter positioning query, water volume data collection, transmission and processing, and saves more costs than centralized meter reading remote transmission. Among many meter reading schemes, this scheme is more suitable for the actual needs of the water supply company. Therefore, the company chose the handheld meter reading machine provided by Tongchuang Technology as the data acquisition based meter reading scheme.  

2 Application of meter reading machine in meter reading management

The application case of meter reading machine in water management of the water supply company fully reflects the application value of meter reading machine in data acquisition, transmission and other application links; The application of the meter reading system of Tongchuang Technology in the company actually represents the mainstream application mode of the meter reading machine in the domestic market. The application of meter reading machine in this company is introduced in detail.

2.1 Query Positioning

When the former meter reading personnel arrive at the meter reading site, they first query and locate the current user's water meter to determine the user's ownership of the meter. The meter reading personnel kept searching for the corresponding meter number, user number, water meter code and other information in the thick meter reading card, which wasted a lot of time and energy; The next step is not performed until it is determined that the user of the "1001" table belongs to Zhang San.  

The application of meter reading machine greatly shortens this tedious and tedious link. Tongchuang Technology provides three positioning methods:

Type query method: open the program menu of meter reading machine, enter the meter number or user number "1001" through the keyboard, and all information about the current water meter will be reflected, including user name address, water meter diameter, water volume of last month, current water volume, copied but not copied and other results.  

Barcode query method: considering the light and shade contrast of meter reading environment, distance, inconvenience for meter reading personnel to read water meter number and other factors, the system supports the query method of laser reading barcode; In this way, a certain length of bar code needs to be pasted on the water meter. The bar code information is mainly character and digital content such as the meter number and user number. Meter reading personnel only need to scan the bar code with a simple key in front of the water meter, and then they can call out the customer information (such as Zhang San) corresponding to the information contained in the bar code (such as "1001") from the database of the meter reading machine, Complete the preliminary water meter positioning operation.  

Preset meter reading sequence method: the function of adjusting the meter reading sequence number is established in the water marketing system. The meter reader arranges the meter card (or meter book, meter book) according to the meter reading sequence of the adjacent water meters in the geographical location, and submits it to the data administrator for input. After the meter reading data is downloaded to the meter reader, the meter reader automatically displays the meter reading sequence number, that is, the adjacent water meters in the geographical location are displayed in sequence.  

Through keyboard type, bar code type and preset meter reading sequence, the process of searching and confirming card information by meter reading personnel is reduced, the work intensity of meter reading personnel is greatly reduced, and the query speed is increased by dozens of times.
