Steam prepayment metering control anti-theft system

Solved the above problems of thermal (power) enterprises, steam users must pay and recharge in advance before opening the valve to use steam (high-temperature water), and must renew and recharge before the balance is exhausted. If not renewed in time, the valve will automatically close and stop steam when the balance is zero, eliminating the phenomenon of steam users defaulting on steam payments. Moreover, early charging and recharging also have a good impact on improving the economic benefits of heating enterprises.

At the same time, this product only adds equipment modifications to the original measuring device, and does not require the elimination or replacement of the original measuring device, protecting the original investment.

This product mainly consists of the following four parts:

1. Prepaid control box;

2. Electric control valve (commonly used butterfly valve);

3. Card reader/writer (including recharge software);

4. Flow meter

Items 1, 2, and 4 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel.

1The main functions of this system include steam prepayment monitoring and on-site instrument data collection, display, storage, and processing of all data transmitted from the user's prepayment monitoring instrument.

2The system is capable of setting alarm limits for key parameters proposed by Party A. The specific alarm limits are autonomously set by the operator based on their permissions. When the collected parameter values exceed the limit, the system will display an audible and visual alarm (screen prompt plus sound prompt).

3The system can also browse and print key parameters, with time accuracy down to seconds.

4The system can set real-time and historical change curves for the parameters proposed by Party A, and the storage time can be up to three years or more, with time accuracy down to seconds..

5In order to store large amounts of data for a long time, the system uses a professional SQL database for storage management.

6This system has good support for most flow calculators on the market, such as Hongrun Instrument, Shangrun Instrument, Tianchen Instrument, Pangu Instrument, etc. If there is no support, our company can develop a driver to support it in the short term.

7The system runs on Microsoft WINDOWS system, including WINXP, WIN7 or server version, which is easy to learn and use.

8The system uses GPRS network provided by mobile network operators for transmission, with simple and reliable communication methods.

9At the same time, the system supports the desktop system, allowing users to view data on their mobile phones or tablets anywhere with a 3G network.
