Principle of work of the present invention is as follows: the present invention is by the cartridge indoor design, and the design of circuit board combines, and provides two cover antennas to use simultaneously in the maximum magnitude.
Circuit structure is described in detail as follows:
System adopts double frequency dual micro processor MCU double circuit, wherein 433MHz high frequency designation system chip adopts the system-level RF chip nRF9E5 of Nordic VLSI company, its built-in nRF905433/868/915MHz transceiver, 8051 compatible microcontrollers and 10 80ksps A/D converters of 4 inputs.Can work in ShockBurst (handling prefix, address and CRC automatically) mode.The built-in voltage adjusting module suppresses noise to greatest extent, and the operating voltage of system is 1.9～3.6V, and carrier wave detects.NRF905 has low in energy consumption, the advantage of reliable operation.It not only at inside solidification according to the wireless data transceiving program of special-purpose short distance communications protocol standard, and finish to the microwave transmitting and receiving circuit clock circuit, memory circuit, being electrically connected of powered battery control circuit by interface circuit.
EEPROM is 25AA320, and 25AA320 is the 32Kb serial EEPROM, communicates by SPI interface and nRF9E5, as the procedure stores carrier of system.Bus signals needs clock input (SCK), and Low-Power CMOS A technology is adopted in data inputs (SI) and data outputs (SO), has protection and built-in write protection that block writes, and high reliability is wiped/write, data preservation 200 years for 1,000,000 times.
Electrify restoration circuit is the special-purpose reset circuit of systematic microprocessor, only when battery is packed into, provide power supply by power-supply controller of electric to microprocessor and main circuit, simultaneously provide reset pulse, to satisfy the requirement that resets that microprocessor starts operation, thereupon to microprocessor, microprocessor is finished initialization, after one section time-delay, system enters the power saving park mode, and the effect of electrification reset finishes thereupon.Unless the replacing battery, otherwise electrify restoration circuit is not restarted.
Power module adopts general circular button cell, 3 volts of power supplys are provided and can charge to system.J6 (BAT) provides power supply by J4 and J5 to smart card during normal the use, and wherein J4 is VCC, and J5 is GND.When charging, charging+utmost point J2 passes through triode T1 resistance R 1 to BAT charging J1, J3 is negative pole, is furnished with the synchronism that realizes storage administration and charging maintenance when depositing in the card case of power supply again, and the design of negative pole symmetry can prevent that card wrong plug mistake from causing damage, and the encapsulation of shell ultrasonic technology can be guaranteed the waterproof and dampproof short circuit that prevents.
The communication of double frequency intelligence designation card realizes
(J4 is anodal to circular button cell by electrode, J5 is a negative pole) power to system, when system powers on, electrify restoration circuit POWER RESET starts, SPI links to each other with the outer 25AA320 of sheet automatically, after nRF9E5 powers on, processor automatically performs the code in the rom boot district, system is according to boot, by pin MISO (data that the SDO of reception EEPROM sends here), SCK (clock signal being provided for the SCK of EEPROM), MOSI (transmitting data to the SDI of EEPROM), EECSN (sending enable signal for the CSN of EEPROM) copies the program code among the EEPROM (25AA320) among the 4KB RAM of nRF9E5 to.After electrification reset is finished, enter the power saving park mode through one section delayed time system.When the card system passes through the inlet induction zone, the built-in 433/868/915MHz transceiver of nRF9E5 receives that by dual-mode antenna and match circuit the 433MHz that access device sends wakes microwave signal up, carrier wave detects (cd) and uprises, microprocessor MCU became 1 second from flyback cycle by 1 minute, become duty and empty the data storage RAM of 4K by the warehouse-in state, automatically detect battery electric quantity, prompting when electric weight is not enough, when receiving an effective address, matching addresses (am) is put height, trigger simultaneously and work under the ShockBurst receive mode, when receiving the rf data bag (access station information and real-time time information) of effective address (the crc verification is correct), nRF9E5 removes lead code address and crc position, matching addresses register-bit (AM) and DSR register-bit (DR) are put height, microprocessor MCU enters low-power consumption mode to the TRX|_CE bottom set, and microprocessor MCU passes through SPI interface sense data with suitable speed.NRF9E5 matching addresses register-bit (AM) and DSR register-bit (DR) are put low.Microprocessor MCU writes nRF9E5 to the address and the data of the contact that will send, it is that height activates nRF9E5 ShockBurst and carries out data transmission that microprocessor MCU is provided with TRX|_CETX|_EN, nRF9E5 adds prefix and CRC check for its data that will send, being converted to the microwave radiation signal by antenna launches, after data send, DSR register-bit (DR) is put height and is notified microprocessor MCU data to dispose, and nRF9E5 enters standby electricity-saving mode.When nRF9E5 and access device carried out the message exchange of 433MHz, IC-card carried out the synchronous communication of 13.56MHz with the inlet read-write equipment, between the two owing to work in the frequency that differs far away and do not disturb mutually.
When induction zone is stood by indicating by the card system, nRF9E5 carries out message exchange with the frequency of operation of 433MHz with the sign station equally, indicate the rf data bag that sends at the station and comprise station information and the real-time time information of indicating, this packet forms the data accumulation storage after being stored in the access station packet.Do not have the IC-card read-write equipment owing to indicate the station, so IC-card does not participate in communication.The unifrequency equipment work that just has only 433MHz in the beacon station system.
When the card system passes through the outlet induction zone, the 433MHz microwave signal that the outlet sensing apparatus sends is detected by nRF9E5, carrier wave detects (cd) and uprises, change duty and carry out the electric weight detection, nRF9E5 is by ANT1 under the ShockBurst receive mode, and antenna that ANT2 connects and match circuit receive outlet station information.ShockBurst send mode nRF9E5 the gateway information of storing among the data storage RAM of 4K and indicate station information and separately temporal information send to the outlet station equipment, the outlet station equipment receives after end-of-data mark delivers microcomputer network to reception information, be in waiting status, wait for next time and triggering.And nRF9E5 sends after the data, and becoming 1 minute from flyback cycle by 1 second, oneself state becomes the warehouse-in state by duty to the end signal trigger automatically, to reduce power consumption.。
