Description
Technical field
The utility model belongs to breaker technical field, be specifically exactly be related to it is a kind of with NFC wireless communication function
Breaker.
Background technique
Traditionally there are two types of the external communication modes of breaker: wire communication and wireless communication.Wherein wired communication mode
It common are Modbus the and Profibus serial bus communication mode based on RS485 bus；Modbus based on Ethernet
TCP, Profinet and Ethernet/IP communication mode；CAN bus based Devicenet communication mode；Communication
The common point-to-point communication mode of such as WIFI, bluetooth based on 2.4G；The short message communication side GPRS, SM based on mobile network
Formula.But these existing communication modes are unable to complete communication in device powers down in practical applications, above-mentioned is several
Either wired mode or wireless mode in communication mode, require equipment normal power supply, if equipment abnormity of power supply, with regard to nothing
Method completes communication.When device context is debugged, can not or just parameter cannot can not be carried out to equipment and matched in the case where device power
Set or obtain the critical datas such as the running log of equipment storage inside.Secondly the Information Security of above-mentioned several communication modes is poor,
In above-mentioned several wired communication modes, either which kind of bus mode can obtain in such a way that bus data is monitored
Complete bus data is taken, is run to equipment and brings threat, and WIFI and bluetooth in communication, belong to point-to-point
Communication mode, if login password is decrypted, can be run to equipment using 2.4G public frequency band and bring larger threat；GPRS and
The Information Security of SM communication mode is preferable, but larger to the dependence of mobile network, if mobile network is unstable, equipment
Possibly data communication can not be carried out；In addition, the communication delay of mobile network determines that both communication modes can not carry out real-time
Higher data transmission.
Utility model content
The purpose of this utility model is aiming at equipment breaker situation existing for above-mentioned existing breaker communication mode
The technological deficiency with Information Security difference can not be communicated down, a kind of breaker with NFC wireless communication function is provided, in open circuit
Increase NFC communication function in device, NFC can power by wireless coil, even if can also complete in the case where device powers down
Data communication；Meanwhile NFC communication chip can carry out multi-layer data encryption, password bad can not just carry out reading data, really
Information Security is protected, NFC communication belongs near field communication, and communication data is by encryption, it is ensured that data in communication process
Invisibility.
Technical solution
In order to achieve the above technical purposes, provided by the utility model a kind of with near-field communication NFC wireless communication function
Breaker, it includes near-field communication NFC antenna, near-field communication NFC communication chip, breaker single-chip microprocessor MCU, and feature exists
In: the near-field communication NFC antenna and near-field communication NFC communication chip pass through connector and breaker monolithic as a whole
Machine MCU electrical connection.
Preferably, the near-field communication NFC antenna and near-field communication NFC communication integrated chip are on one piece of pcb board.
Preferably, the near-field communication NFC communication chip interior is integrated with non-volatile memory medium.
Preferably, the near-field communication NFC communication chip is provided with the driving of near-field communication NFC antenna and serial communication connects
Mouthful.
Further, the near-field communication NFC antenna connect with external near field communication NFC device and receives from external near field
The radiofrequency signal of NFC device is communicated, and the radiofrequency signal from near-field communication NFC communication chip is sent to external near field communication
NFC device.
Preferably, the external near field communication NFC device is the mobile phone or tablet computer of near-field communication NFC function.
Beneficial effect
A kind of breaker with NFC wireless communication function provided by the utility model, increases NFC communication in breaker
Function, NFC can be powered by wireless coil, even if can also complete data communication in the case where device powers down；Meanwhile
NFC communication chip can carry out multi-layer data encryption, and password bad can not just carry out reading data, it is ensured that data safety
Property, NFC communication belongs near field communication, communication data process encryption, it is ensured that the invisibility of data in communication process.
Detailed description of the invention
Attached drawing 1 is the connection relationship diagram of the utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further.
