7. Application of electronic signature seal on water meter

7.1 Recommend the application of electronic signature and sealing meter reading system in tap water business

The progress of science and technology has brought a large number of new products and new technologies. The application of new technologies and new products can greatly improve work efficiency and create good social and economic benefits.. For the water industry, how to manage water meters and recover water fees is an important guarantee for the stable production and operation of water companies. At this stage, some water companies in China have taken the lead in adopting hand-held meter reading machines. To a certain extent, the work efficiency of meter readers is improved, and the accuracy of meter reading is also improved, creating good social and economic benefits. However, the application of the meter reading machine can only solve the problem of manual meter reading. At the same time, in practical applications, there are limitations such as the need to prepare the circuit in advance and manually check the meter number.

To solve the problems in the application of the handheld meter reading system, the remote meter reading system can be used to solve it, but this method requires the replacement of traditional water meters, and involves floor wiring, water meter replacement and other issues. The high cost is also the reason that hinders the large-scale replacement of the city.RFIDThe emergence of the electronic signature-sealed meter reading system has solved these problems very well.RFIDThe electronic signature seal replaces the traditional lead seal, which can play the advantages of non-removal, stealing and imitation, and at the same time improve the anti-counterfeiting and anti-theft performance of the water meter, and has extremely high security and reliability. On this basis, the cost of technical transformation is far lower than the cost of replacing the water meter. The key point is that the new electronic signature-sealed meter reading system solves most of the problems of the traditional hand-held meter reading machine, and effectively prevents the meter reader from reading the meter. In the process of estimating copying, wrong copying and many other phenomena.

7.2 meter reading

Electronic signature (RFID) type meter reading systemIn addition to the advantages of anti-counterfeiting and anti-theft, the more important thing is that it is combined with a meter reading machine, which replaces the manual copying process in the traditional meter reading process, reduces errors and improves efficiency.

It works as follows:

1. Data download: Download the household information to the meter reading machine with specific data transmission software (for example: household name, household address, meter code, last month’s travel degree, etc.). Download household information to a meter-reader-specific template.

As shown below:

2. collectionIDNo.: Each electronic tag has a unique oneIDnumber, using a meter reading machineIDWith the function of number collection, each user is bound to the corresponding electronic tag one by one. When the electronic seal is installed, the code reading operation can be performed on the electronic seal with a meter reading machine.

The interface of the handheld is shown in the figure below: (For specific operations, see the manual of the handheld)

3. Meter reading: The meter reader only needs to use the meter reading machine to read the electronic labelIDnumber, the program will automatically call up the corresponding user information, and then enter the reading of the gas meter this month. The meter reading machine can download more than 20,000 pieces of user information at most (32M), when the data reading of one or several districts is completed, the data is uploaded to the owner’s charging system, and the meter reading task can be downloaded again.

8. The effectiveness of the product for you

8.1 Improve corporate image

With the popularization of informatization, various industries now pay attention to the application of new products and new technologies in the enterprise. The popularization and application of hand-held meter reading machines and electronic signature seals make the water company’s daily contact channel with users – reading This part of the meter has really realized informatization and is actually displayed in front of the users, which has played a positive role in improving the social image of the water company, regulating the meter reading personnel of the water company, etc., and has greatly increased the water consumption. The social efficiency of the company.

8.2 Improve regulatory tools

As an indispensable part of the daily work of the water company, the meter reader plays a very important role in the work system of the water company. However, the meter reader often goes out to work and the mobility is very strong, so it is difficult for the daily supervision methods to play a role. To the effect, both the manual meter reading and the handheld meter reading machine cannot distinguish the difference between the estimated copy and the actual copy. The Longquan electronic signature and sealing meter reading system solves this problem very well. The meter reader must be on the spot to read the meter. If it is really necessary to estimate the reading, the manager can also effectively count the estimated reading situation and analyze the uploaded data. Thereby improving the management’s supervision methods.

8.3 Improve the anti-theft and anti-counterfeiting of water meters

In recent years, with the gradual development of the market economy, there have been phenomena such as users replacing water meters without permission in some areas, and the traditional lead seal sometimes cannot be judged. Extremely reliable anti-theft, disassembly, theft and imitation will cause very obvious damage to the product body; at the same time, the seal has its own chip inside, which is the only one in the world.IDThe chip cannot be imitated after being damaged by external force, so that the product has extremely high anti-counterfeiting performance.

8.4 Promote the application of meter reading machine

At this stage, almost all water companies have established charging systems. The meter reading methods are mainly based on manual meter reading and meter reading by meter reading machine. In the end, manual meter reading still requires the staff to perform secondary input to form electronic data. The probability of errors is greatly increased in the second entry process; the traditional meter reading machine has its own shortcomings (to prepare lines, small capacity, slow speed), which lead to the rejection of meter reading personnel, and most of the data are entered after reading the meter by handbook. The result of this is to increase the difficulty and workload of meter reading. Longquan electronic signature and seal meter reading system can truly realize disordered meter reading and completely solve the problem of pre-programmed lines. With the continuous development of new technologies, the meter reading machine adopted by our company at this stage has many advantages in machine frequency, storage capacity, data index, etc. The big improvement solves the problems of small capacity and slow speed. The emergence of Longquan electronic signature and seal has brought the application of meter reading machines to a new level. The Longquan electronic signature and sealing meter reading system is the perfect meter reading solution at this stage.

8.5 On-site analysis and data update timeliness is strengthened

The Longquan electronic signature and seal meter reading system can establish an interface with the charging system to realize data comparison and update. When the user data changes, it can be reflected in the charging system after the update is performed during the meter reading process. For example, the water meter needs to be detected, reversed, damaged, etc., which can be directly reflected in the charging system to realize data update. The new model of meter reading machine improves the computing power and adds the analysis functions required in the meter reading process, such as: data Comparative analysis, abnormal judgment, etc.
