One meter multi card charging management system

Feature Overview
The TECH201 TM card intelligent electricity management system is developed by our company for the electricity consumption status of urban and rural public electricity facilities. It is applied to rural irrigation and small and medium-sized power users as a prepayment management system for electricity metering. This system is a high-tech product that integrates advanced TM (TOUCH Memory) technology into mature technologies such as microcontrollers, computers, and automatic control. It successfully solves the problems of inconvenient electricity management, difficult charging, and serious waste for rural irrigation and small and medium-sized power users. It can provide safer, more reliable, and more convenient control methods for electricity management in the power system.

TECH201 village level card dispenser (see page three for details)
TECH201 Intelligent Electricity Management System Software (see page four for details)

Product Features
Convenient management, the power department only needs a few management cards and supporting software to uniformly manage the metering control of the entire city and county.
● Easy to use, users only need to briefly touch the TM card slot to complete the power on/off operation.
Equipped with a village level card dispenser, it is a new type of card dispensing device that is convenient for villagers, low-cost, highly reliable, and easy to operate.
Equipped with functions such as digital display of remaining battery life, automatic control, and pseudo card recognition, it is convenient and easy to use, with stable performance and high reliability.
Using the patented technology achievement iButton information button from Dallas, USA as the control card, it has high and low temperature resistance, waterproof and moisture-proof, anti-corrosion, friction resistance, anti-static, impact resistance and other properties.

Product Usage
This product is mainly used for rural irrigation and can also be used for other small and medium-sized power users. Its overall performance and reliability are at the leading level in China, making it the preferred supporting facility for rural power grid renovation.

Main technical parameters
Rated voltage: AC380V
Working temperature: -45 ℃~+85 ℃
Relative humidity: 0~95% (non condensing)
● Electrical strength: ≥ 2000V

Feature Overview
◇ Control device power failure protection function
When a user suddenly loses power while using electricity, the intelligent power control device will automatically save the remaining power of the current user, and can continue to be used when the power grid is reconnected.
◇ Power outage protection function
During the user's power consumption process, if any phase of the three-phase system experiences no voltage (or low voltage), the intelligent power control device will automatically cut off the power supply, achieving phase loss protection for the motor and effectively protecting it.
◇ The electric meter has no pulse protection function
When the intelligent power control device fails to detect the output pulse of the electricity meter after a period of time (the length of time can be set) (abnormal damage to the electricity meter), it will automatically cut off the power and write the remaining power into the EEPROM for storage, minimizing losses caused by abnormal damage as much as possible.
◇ Password protection function
This system uses the iButton information button, a patented technology achievement of the Dallas company in the United States, as the control card. The card itself has an 8-byte password verification area, and only the password is correct can read and write operations be performed on the card. In addition, it uses the globally unique 64 bit serial code that cannot be replicated on the card to achieve internal data encryption, completely eliminating the possibility of card duplication.
◇ Group management function
The management department can group several villages according to the actual situation. User cards and related management cards can only be used within their own group and cannot be used in other groups. In the event of malicious damage, it will not cause losses to other groups and minimize possible losses. Product Features
The main feature of this product is the use of the patented technology achievement iButton information button from the Dallas company in the United States as the control card. The iButton information button is a microcomputer chip packaged in a flat circular stainless steel shell, with bidirectional communication function. The data transmission uses a unique single bus protocol, and the information transmission between the information button and its reader/writer can be completed with only a brief contact. In addition, each TM card has a unique registration number, which is permanently engraved on the ROM by laser during the generation process and cannot be replicated.

Introduction to functional features
The TECH201 village level card dispenser is a new type of card dispensing device developed by our company in response to the current situation in rural areas in northern China, consisting of a microcontroller, a micro printer, and other components. It is a management device that can integrate functions such as issuing cards, paying fees, and reporting losses.
The municipal and county power departments can set the sales capacity of village level card vending machines. When the village level card vending machines sell out of this electricity, they must recharge at the municipal and county power departments, otherwise they cannot continue to be used; The village level proxy card dispenser is equipped with a large capacity storage device, which can store all payment records and upload them to the main control computer of the city or county power department through the communication interface on the card dispenser. Through the above two points, village level card vending machines have also achieved unified management of rural irrigation electricity by the power department.
In addition, compared to ordinary payment points consisting of computers and general-purpose printers, it has the following advantages:
We have implemented a payment point for each village, eliminating the need for villagers to travel to distant payment points, which has been widely welcomed by the villagers.
Compared with the traditional model of adding a computer and a universal printer, it greatly saves customers' investment.
The village level card dispenser is composed of a microcontroller, dot matrix LCD, micro printer, etc., with high reliability.
Adopting a large LCD display and a fully Chinese menu, it is easy for managers to operate.
For remote rural areas where residents are not concentrated, it is easier to promote than ordinary payment points.

System human-machine interface


Introduction to functional features
◇ Software development platform:
Developed using the popular and powerful development software C++Builder 5.0 in China, the standalone version uses Paradox7.0 small database, while the online version uses Microsoft SQL SERVER 7.0 large database.
◇ System interface
Using WINDOWS interface, the operation is simple and easy to master.
◇ Card operation:
Through this software and its accompanying TM card reader/writer, users can create user cards, make user card payments, cancel user cards, and make up user card payments. The operation is convenient and simple. It is also possible to create functional cards such as proportion cards and electrician cards through this system, which is convenient for managers to manage.
◇ Query and reporting functions:
Through this system, daily and monthly reports can be created to facilitate the design work of staff; It is also possible to query user cards, proportion cards, and payment records for the convenience of staff.
