Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides a kind of dsm controller controlled based on mobile phone NFC communication, comprises single-chip microcomputer, electric energy metering module, NFC module, remote signal sending module, power-off modular, memory module, Wi-Fi module, wireless communication module, display module, timing module, power module; Wherein each functional module specifically describes as follows:
Single-chip microcomputer, adopts embedded ARM processor, for controlling electric energy metering module, sampling current value and sampling voltage value is converted into energy value, and memory module is stored in energy value; Be responsible for the operation of whole dsm controller associated communication and control relative program.
Electric energy metering module, for current value and magnitude of voltage are converted into energy value, and is converted into the electricity charge amount of money; Its input end connects sampling chip, and the input end of sampling chip connects three groups of current transformers.Current transformer provides current value and magnitude of voltage to sampling chip, and sampling module is used for sampling current value and magnitude of voltage.
NFC module, adopt NFC controller and the NFC safety chip of company of Infineon, NFC controller is connected with single-chip microcomputer by SPI interface, and NFC safety chip is connected with NFC controller; For carrying out wireless connections with the mobile phone with NFC chip, by NFC module, user mobile phone can carry out Online Payment charging, reads power consumption information.
Remote signal sending module, adopts 433MHz or 315MHz wireless module, for sending power cut-off information to the remote control signal receiving module be connected with power-off execution module.
Power-off modular, the power-off execution module comprising remote control signal receiving module and be connected with remote control signal receiving module.Remote control signal receiving module and remote signal sending module carry out radio communication, receive the power cut-off information that remote signal sending module sends, and power-off execution module disconnects power circuit after receiving the wireless power-off signal of remote control signal receiving module output.Remote control signal receiving module adopts 433MHz or 315MHz wireless module, and power-off execution module adopts isolating switch.
Wi-Fi module, adopts the integrated transceiver of TI company and the integrated module of protocol stack, is connected by USB, UART or SPI and single-chip microcomputer.
Wireless communication module, adopts the communication module based on 6LoWPAN wireless sensor network, is connected with single-chip microcomputer by UART or SPI interface.
Display module, adopts LCD display, the power information of display user and payment information.
Timing module, for providing the clock circuit of clock signal in real time.
Power module, for the utility model is powered.
Principle of work of the present utility model:
1, the process using the mobile phone possessing NFC function to complete charge to supplement with money is as follows:
First user goes to electric company business hall to register, and completes key registration and the exchange of the utility model and NFC smart mobile phone; User waits Third-party payment mode to be that NFC mobile phone wallet is supplemented with money by mobile-phone payment treasured; By NFC smart mobile phone near NFC module, mobile phone and ammeter set up secure connection by NFC, carry out identity validation; After authentication completes, by connecting based on 6LoWPAN wireless sensor network and electric company backstage, upgrading load value data, completing and supplement operation with money; Complete after supplementing with money, LCD display and user mobile phone APP point out charging information simultaneously, accounts information and of that month power consumption.
2, the cellphone subscriber that difference possesses NFC function obtain user power utilization information or running log, failure message process as follows:
By mobile phone near NFC module, exchanged the identity of both sides by NFC, the MAC Address of both sides and Wi-Fi password, carry out automatic Verification, sets up Wi-Fi secure connection; Different data, according to the difference of user identity, are sent to mobile phone by dsm controller; If electricity consumption user, dsm controller connects startup transmission process by TCPSocket, and by the power use by time shearing information of user, accounts information etc. are sent on the mobile phone of electricity consumption user, result is shown to user by corresponding APP by mobile phone, so that user checks data; If testing staff, dsm controller connects startup transmission process by TCPSocket, is sent on the smart mobile phone of testing staff by the operation information etc. of dsm controller, and smart mobile phone passes through corresponding APP to data analysis, localizing faults.
3, when electric energy metering module calculates user power utilization overdraw arrearage, by the remote control signal receiving module transmission power-off signal of remote signal sending module to power-off modular, and export to power-off execution module isolating switch, realize the disconnection of on-load switch in user power utilization circuit, remote signal is adopted to communicate between dsm controller with power circuit, instead of original electric wire and connect Control on Communication, defaulting subscriber is difficult to remote signal of the present utility model to cut off, and solves electricity consumption overdraw Problem of Tuition Dues preferably.
