Description

Sefe declaring and paying controller

The present invention relates to domain charging control technologys such as electric power, tap water, combustion gas, heat supply, especially a kind of control device that utilizes electronic technology by user's Sefe declaring and paying.

Along with the development of power line carrier, PLC technology, this technology begins to be applied to the work of checking meter in fields such as electric power, tap water, combustion gas, heat supply, to overcome all drawbacks of manually manually checking meter and being brought to the doorstep.The principle of work of this charging mode is as follows: utilize the power carrier communication technology, finish by existing supply line and to check meter, by docking with bank payment system, reach the counting cost by gas meter purpose, the data of checking meter up simultaneously can be used for the various management of relevant department.

Because line of electric force transmits electric energy to consumer, rather than be used for transmitting data, so line of electric force is a lot of to limiting transmission of data, height reduction on the line of electric force, strong noise, high distortion, strong jamming etc. make line of electric force become a medium of communication that laser propagation effect is relatively poor, although adopted technology such as spread spectrum, but the electric equipment of following aging circuit, user power utilization situation and use all can't be expected, makes the power carrier kilowatt meter reading-out system have certain technical risk.In order to reach higher reliability, the cost of this type of scheme is quite high.

In addition, relevant department is according to the data of checking meter up, calculate expense after, generally be authorized bank's charge, the user needs to open an account and deposit the corresponding amount of money in appointed bank, perhaps, needs the user to pay dues to the bank of appointment.At wide geographic area backward in economy, particularly rural area, it is bigger to carry out difficulty.Moreover the power carrier communication coverage is shorter, in order to use in a big way at one, need install repeater additional, on the one hand can be further the reliability of reduction system, on the other hand, can strengthen the maintenance cost in the use.

In fact, no matter be electric power, tap water, coal gas, or heat energy, data are all very short, fully can not need check meter, and declared by user oneself.

The object of the present invention is to provide a kind of Sefe declaring and paying controller, it comes image data without power carrier, but is regularly declared by user oneself, and declaration data is through the encryption of this device.The user can declare by phone, mobile phone, internet, buys corresponding rechargeable card simultaneously and supplements with money and pay dues, and need not the user and builds the family deposit in bank, also need not the user and pays dues to the appointed place.Certainly after the user also can write down these data, directly pay dues to specific office.After the user pays dues, can obtain one and add close affirmation data, the user utilizes keyboard that the affirmation data are imported this device, after the deciphering of this device, promptly know user's declare paying situation, declare paying not yet if the user exceeds the time limit, this device will be carried out rupturing operation, force user's declare paying.On the one hand, confirm data, declaration data through the encryption of this device, safe and reliable, on the other hand, the present invention utilizes the existing communication resource, greatly reduces equipment cost, because no intermediate equipment, the maintenance cost in the use also greatly reduces.

The object of the present invention is achieved like this:

A kind of Sefe declaring and paying controller, it is characterized in that: its control circuit is made up of single-chip microcomputer, keyboard, sensor for countering, cut-out topworks, display and real-time timepiece chip, single-chip microcomputer input port line connects sensor for countering, the keyboard that is installed on the base table, single-chip microcomputer output port line connects and cuts off topworks, display, and input, output port line also are connected to real-time timepiece chip and are used for the serial EEPROM of store data.

Above-mentioned keyboard can be directly and the single-chip microcomputer incoming line join, it also can be the Wireless Keyboard that joins by other carriers and single-chip microcomputer, such as being formed by receiver module that is installed in the single-chip microcomputer input port and the hand-hold wireless keyboard coupling by carriers such as infrared ray, radiowave transmission key information, carrier can be infrared ray, radiowave etc.

Above-mentioned real-time timepiece chip is mainly this device the precise time benchmark is provided, and reaches regularly to declare purpose, can be special-purpose real-time timepiece chip, also can be realized by software mode by single-chip microcomputer.

Aforementioned display device can be made up of LCD or LED charactron.Cutting off topworks can be magnetic latching relay or magnetic holding solenoid valve.

The said counting sensor can be mounted in optoelectronic multiplex switch, the Hall switch on the counting base table dial, or tongue tube.
