This steam prepayment system is amazing, intelligent, easy to manage, and also anti-theft

At present, most thermal (power) enterprises supply steam first and then settle the payment every month when selling steam. However, there may be some user units who find various reasons to delay payment, which increases the financial turnover difficulties of heating enterprises. The steam prepayment control system developed by Weifang Xinte Automation Instrument Co., Ltd. is a product launched to solve the above situation.

The use of this product solves the above problems for 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:

1Prepaid control box;

2Electric control valve (commonly used butterfly valve);

3Card 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

Technical General Provisions

According to the technical requirements of the thermal energy metering system, a secondary thermal energy temperature and pressure compensation instrument is installed after the primary metering device (temperature, pressure, flow sensor) to compensate for the temperature and pressure of the flow measured in the first measurement, and obtain the true operating flow rate. In order to meet the needs of remote management and monitoring, this system utilizes GPRS modules, IC card monitoring unit communication interfaces, and networks provided by mobile operators to achieve real-time remote transmission of data from multiple dispersed measurement monitoring points.

The system currently consists of user sub stations (which can be easily expanded to 100 or more user sub stations) and a main station. Each user sub station is equipped with an IC card prepaid monitoring box. The main station consists of a system platform server, laser printer, UPS power supply, system platform monitoring software, and IC card recharge management software. The main station and sub stations rely on the GPRS network for data and prompt reporting.Weifang Xinte Automation Instrument Co., Ltd.

At the same time, the main station server has a network interface (if multiple microcomputers need to share data resources, the main station computer needs to have two independent network cards), and other computers can browse all data on the host using IE through the network, and can easily manually or automatically print various reports (daily reports, monthly reports, statistical reports, etc.), data change curves (real-time curves, historical curves, etc.), various prompts and alarm records, etc

System Introduction

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 can set the key parameters proposed by Party A, and the specific reporting limits are set by the operator according to their permissions. When the collected parameter values exceed the limit, the system will display an audible and visual alarm (screen prompt and sound prompt).Weifang Xinte Automation Instrument Co., Ltd

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.Weifang Xinte Automation Instrument Co., Ltd

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.

Prepaid controller function:

Safety:adopt2Manage and operate IC cards, device management cards, and user purchasesGas card; Cards and tables correspond one-to-one and cannot be used interchangeably. Three consecutive password verifications result in loss of purchase,ICThe card will lock and no more data writing operations can be performed. The operation of the device and the modification of parameters must be done with a device card inserted, which is more reliable than password protection.
Display function:Instantaneous flow rate, cumulative flow rate, remaining gas volume, differential pressure, frequency, pressure, temperature, valve position, etc.
Reminder function:When the IC card is used incorrectly (when the IC card function does not match the operation performed), the LCD screen displays relevant prompt information and the operation is invalid.Weifang Xinte Automation Instrument Co., Ltd
Valve closing function:After the purchase of steam is completed, the valve will automatically close. The valve closing action can be set according to the actual situation, such as closing 50%, 40%, or 30%, or fully closing, and the specific value is set by the user themselves.
Power off protection function:The raw data can be saved for ten years during a power outage.Weifang Xinte Automation Instrument Co., Ltd

Data recovery function:In the event of accidental damage to the controller, internal data (mainly user recharge balance) can be restored, effectively avoiding disputes between both parties.Weifang Xinte Automation Instrument Co., Ltd
Abnormal situation report or upload:The system provides prompts and reports for the following four situations
A、 According to user settings, when the balance of the gas fee is less than the set reporting value, it will be reported (on-site sound and light).
B、 After the prepaid monitoring box opens, it will prompt the upper monitoring computer.

C、 After the interruption of the mains power (AC220V), the upper monitoring computer will prompt.Weifang Xinte Automation Instrument Co., Ltd

D、 The upload of valve position, flow rate and other data can be set in any way by the upper computer. You can also choose to send text messages.
Flexible setting of communication parameters:The communication address and baud rate of the prepaid controller can be set as needed (address range: 1-128, baud rates: 2400, 4800, 9600).

Valve adjustment function:Weifang Xinte Automation Instrument Co., Ltd

1. In manual mode, after flashing the device card, the valve opening can be adjusted through the keyboard.

2In automatic mode: After recharging, the valve slowly opens automatically.

3Equipped with remote control mode, valve opening and closing can be adjusted through the upper computer. .

4It has debugging function, and in debugging state, the valve can be opened without recharging.

The above functions can be enabled or disabled through the function menu of the controller. When the balance is used up, the valve will automatically close.
Overdraft function:By using permission settings, such as using the "Device Management Card", the "Overdraft" function can be selected through the function settings key. The large overdraft limit can be set by the gas provider themselves. In the event that the user's balance is exhausted, they can also overdraw a certain amount of gas for use.Weifang Xinte Automation Instrument Co., Ltd

High computational accuracyThe deduction of recharge amount, accurate to 0.001 tons, ensures the interests of both supply and demand sides.

Convenient recharge：When recharging with an IC card, there is no need to manually convert it into gas volume. Simply enter the amount and the software will automatically calculate the gas volume based on the unit, accurate to 0.01 tons.

Price management:Different gas prices can be set in the recharge software according to different users, and can be modified at any time.Weifang Xinte Automation Instrument Co., Ltd
