Abstract
The utility model discloses a gas meter in a prepaid meter reading payment mode. The gas meter comprises a master control MCU (Microprogrammed Control Unit), and further comprises an NFC (Near Field Communication) control unit and an NFC safety unit. The NFC control unit is provided with an antenna for communicating with an outside NFC mobile phone; and the NFC control unit communicates with the master control MCU through an I2C bus, and communicates with the NFC safety unit through an SWP (Single Wire Protocol). The gas meter provided by the utility model supports the mode that users read the meter by the mobile phone locally and pay the cost remotely, so that the users can prepay the gas cost by the NFC mobile phone without going out.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter intelligent gas meter that prestores and copy the pattern of paying.
Background technology
Existing intelligent gas meter generally is made up of master controller, metering circuit, storer, relay control unit, infrared interface, RS485 interface, keystroke interface etc.; This gas meter, flow meter is present more advanced table; Can realize remote automatic meter reading, then through sales counter pay the fees or network pay the fees or note pay the fees or bank deduct fees automatically.But this combustion gas can't be supported the wireless mode of far copying at some applied environment, and gas company system in backstage can't obtain customer consumption information, can't confirm the consistance of subscriber payment and actual amount receivable.
The utility model content
The purpose of the utility model is to provide a kind of and realizes that user mobile phone this locality prestoring of remote payment of checking meter copy the gas meter, flow meter of the pattern of paying.
This prestoring that the utility model provides copied the gas meter, flow meter of the pattern of paying, and comprises main control MCU, also comprises
NFC control module and NFC safe unit, NFC control module have antenna and are used for and extraneous NFC mobile communication, pass through I between NFC control module and the main control MCU
2The C bus communication and is communicated by letter through the SWP single-wire-protocol between the NFC safe unit.
Owing to be provided with NFC control module and NFC safe unit in the utility model gas meter, flow meter, the NFC mobile phone can be communicated by letter with it, therefore can bring following advantage:
(1) message exchange between this gas meter, flow meter and the NFC mobile phone is safe, convenient.Because between this gas meter, flow meter and the NFC mobile phone is contactless communication mode, therefore use very convenient; Owing to all introduced the NFC safe unit in this gas meter, flow meter and the NFC mobile phone, in the process of exchanges data, will carry out the operation of a series of encryption and decryption, signature and certifying signature in addition, so communication between the two is safe;
(2) information interactive process between this gas meter, flow meter and the main website can guarantee information privacy, integrality and freshness.This gas meter, flow meter can be supported the bidirectional information authentication between self and the main website.Through between gas meter, flow meter and main website, sharing private cipher key, and to mutual information carry out encryption and decryption and signature operation, can guarantee that institute's interactive information is not distorted between the two, thereby guarantee the privacy and the integrality of data.Through in interactive information, inserting the variable quantity relevant with the time, freshness that can guarantee information, thus prevent Replay Attack.Correspond to gas company and pay the fees and use, more than three kinds of securities can prevent the malicious user eavesdropping, distort the amount of money or repeatedly use the same information of paying the fees to supplement with money of paying the fees;
(3) saved construction cost and the maintenance cost that gas company is used for remote system; After using this gas meter, flow meter; Gas company can save original remote system, accomplishes the work of checking meter, paying the fees and prestoring by the user, has saved the construction and the maintenance cost of remote system.Do not having under the pattern of remote system, gas company adopts the pre-payment pattern to come the NFC gas meter, flow meter is controlled;
(4) personnel that saved gas company drop into, and original sales counter business personnel quantity will reduce significantly;
(5) realized that the combustion gas expense copies the integrated of the process of paying, made things convenient for the user.This gas meter, flow meter is supported user mobile phone this locality remote payment pattern of checking meter, and the user can use the pre paid functionality of NFC mobile phone completion combustion gas expense with " stay indoors ".

Embodiment
The NFC technology is a design object with the near field payment of specialty always; Having safe, terminal relies on mobile phone to solve that (NFC is received and write standard by mobile phone industry; Add the mobile phone that the numerous manufacturers of nokia, htc, three magnitudes of this standard release and all will possess the NFC function), cost lower (configurating terminal machine separately), advantage such as easy to use; The NFC mobile-phone payment is classified as standard by China Unionpay simultaneously, and domestic bank can both receive the payment of this kind mode, is more conducive to promote.The utility model is implemented only to need to increase the NFC module in the existing intelligent gas meter table, promptly increases NFC control module and NFC safe unit, and with passing through I between NFC control module NFC control module and the main control MCU
2Communicate by letter through the SWP single-wire-protocol between the C bus communication, NFC control module and NFC safe unit.Just can realize the contactless information security exchange channels between the utility model gas meter, flow meter and the NFC mobile phone.
Fig. 1 has reflected the structure of the utility model; Can find out that from this figure the utility model still has main control MCU, power circuit, metering circuit, storer, relay control unit, infrared interface, RS485 interface, keystroke interface, liquid crystal display etc.; Also have NFC control module and NFC safe unit; The NFC control module has the antenna with extraneous NFC mobile communication, is responsible for the information interaction between control and NFC mobile phone, NFC safe unit and the main control MCU.The NFC safe unit is responsible for carrying out security-related algorithm, and output result of calculation is given the NFC control module.Communication mode between NFC control module and the main control MCU is I
2C bus communication mode, the communication mode between NFC control module and the NFC safe unit is the SWP single-wire-protocol.
Claims (1)
1. one kind prestores and copies the gas meter, flow meter of the pattern of paying, and comprises main control MCU, it is characterized in that also comprising NFC control module and NFC safe unit, and the NFC control module has antenna and is used for and extraneous NFC mobile communication, passes through I between NFC control module and the main control MCU
2The C bus communication and is communicated by letter through the SWP single-wire-protocol between the NFC safe unit.
