1 Basic situation analysis
Before using the meter reading machine, the water supply company used manual and card meter reading methods. This method has significant deficiencies: for example, the handwriting is not clear when manually writing the water volume, and there is a slight error when transcribing data to the PC; Meter reading personnel can only estimate and read meters when they are not at the site, and cannot read meters in place; The meter reading personnel may not copy as much as they know about the water volume of users, and "love water" may simply occur; The power of manual meter reading is low. In the aspects of inquiry, recording and transmission, the manual operation method greatly reduces the operating power. Therefore, the company initially looks for a more useful disposal scheme for meter reading. The use of meter reading machine based on the water supply promotion and management information system plays an immeasurable role in the positioning and query of water meters, collection, transmission and disposal of water volume data, and saves more costs than the remote transmission of centralized meter reading. Among many meter reading schemes, this scheme is more suitable for the practical needs of the water supply company. Therefore, the company chose the handheld meter reading machine provided by Tongchuang Technology as the basic meter reading scheme for data collection.
2 Use of meter reading machine in meter reading processing
The use cases of meter reading machines in the water supply company's water management all reflect the use value of meter reading machines in data collection, transmission and other use links; The meter reading machine system of Tongchuang Technology represents the mainstream use method of meter reading machines in domestic shopping malls in the company's use practice. The use of meter reading machine in this company is introduced in detail.
2.1 Query Positioning
When the former meter reading personnel arrived at the copying site, they first queried and located the current user's water meter to determine the user's ownership of the meter. Meter reading personnel constantly search for the corresponding meter number, user number, water meter code and other information in the thick meter reading card, wasting a lot of time and energy; The next step is only carried out after it is determined that the user of table "1001" for example belongs to "Zhang San".
The use of meter reading machine greatly shortens this vulgar and tedious link. 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 will be reflected, including user name address, water meter diameter, water volume of last month, current water volume, water volume that has been copied but not copied, etc.
Barcode query method: considering the factors such as light and dark comparison of meter reading environment, distance, inconvenience for meter reading personnel to read water meter numbers, the system supports the query method of laser reading barcode; This method requires a certain length of bar code to be posted on the water meter. The bar code information mainly includes the meter number, user number and other characters and digital content. Meter reading personnel only need to scan the bar code briefly before the water meter, and then the customer information (such as Zhang San) corresponding to the information contained in the bar code (such as "1001") can be retrieved from the database of the meter reading machine, End the preliminary water meter positioning operation.
Preset meter reading sequence method: the function of adjusting meter reading sequence number shall be established in the water use promotion system. The meter reader shall sort out the meter reading sequence of meter cards (or meter books, meter books) according to the adjacent water meters in the geographical location, and submit them to the data handler for input. After the meter reading data is downloaded to the meter reader, the meter reader main action flashes according to the meter reading sequence number, that is, the adjacent water meters in the geographical location flash in sequence.
Through keyboard type, bar code type and preset meter reading order, the process of card information searching and recognition by meter reading personnel is reduced, the work intensity of meter reading personnel is greatly reduced, and the query speed is advanced dozens of times.
