See also shown in the accompanying drawing, the invention will be further described.
The objective of the invention is to delete module identical with function in the mobile phone in the portable read-write machine, communication, the powering mode of optimization and mobile phone reduce the read-write power consumption, to reach the purpose that reduces cost, volume and weight.
As shown in Figure 1, the invention provides a kind of portable radio frequency read-write assembly for mobile phone, mobile phone 1 and radio frequency read-write assembly 2 both be separates, independently install each other, radio frequency read-write assembly 2 uses as the Function Extension spare of mobile phone 1, and both nationalitys help USB or serial ports or 3 communications of 1394 multiple interfaces.After both were connected, radio frequency read-write assembly energy automatic identification mobile phone model was set up corresponding communication and is connected, and reads and writes assembly 2 work by mobile phone 1 control.Wherein, radio frequency read-write assembly 2 is provided with radio frequency module for reading and writing 201, communication management module 202, power management module 203.
The concrete function of each module is as follows:
For different application, less radio-frequency RFID module for reading and writing can be comprised of the less radio-frequency RFID module for reading and writing 201 of one or more frequency ranges, less radio-frequency RFID module for reading and writing 201 is after receiving mobile phone 1 control command that communication management module 202 sends, by the information in the less radio-frequency RFID antenna read-write RFID label, and the result is transferred to mobile phone 1 by communication management module 202, thereby realize the operation that 1 couple of less radio-frequency RFID of mobile phone label is finished inquiry, identifies, reads and write.
Preferably, described communication management module 202 can be identified the mobile phone 1 that connects automatically, and serial ports, USB, the multiple communication modes such as 1394 are provided.
Preferably, described power management module 203 can the various powering modes of automatic discrimination, except for less radio-frequency RFID module for reading and writing 201 provides electric power, can be mobile phone 1 charging simultaneously;
Preferably, described less radio-frequency RFID module for reading and writing 201 adopts the less radio-frequency RFID module for reading and writing of low-power consumption, to reduce power consumption, extends working time.
Preferably, described less radio-frequency RFID module for reading and writing 201 adopts directed less radio-frequency RFID read-write antenna, guarantees the readwrite performance that under low-power consumption mode one party is made progress.
In order to improve the communication efficiency of module and mobile phone 1, communication management module 202 can also be added data storage elements, and the data that module obtains are carried out the redundancy processing, perhaps the control command of module for reading and writing is carried out secondary encapsulation, to improve applicability of the present invention.
Shown in Fig. 2 workflow diagram of the present invention, the program circuit of assembly is as follows:
1) when the external interface of radio frequency read-write assembly 2 with after mobile phone 1 links to each other, judge that radio frequency reads and writes the external interface of assembly 2 whether signal is arranged, go on foot if no signal then turns the 1st;
2) signal condition being arranged, judge whether it is that serial ports connects, is then to adopt the standard serial port pattern; If USB connects, then the USB holotype control chip of communication management module 202 applies 5V voltage in the power pins of USB, drive the USB of mobile phone from chip operation, and read a series of data from USBD+/D-and be used for to confirm the cell phone apparatus feature, such as vendor ID, product ID, interface working method, the parameters such as power consumption;
3) communication management module 202 is by the parameter comparison activation bit storehouse of above-mentioned acquisition, differentiate mobile phone model, and the communication protocol supported of mobile phone, and the communication mode of automatic and mobile phone 1, and the connection corresponding with mobile phone 1 foundation, set up module for reading and writing in application layer simultaneously and be connected with the transparent transmission of mobile phone 1;
4) judge whether and need to carry out charging operations to mobile phone,
If do not need charging then to turn the 6th) step;
5) if need charging, then 203 pairs of mobile phones of power management module charge;
6) judge whether mobile phone has read write command, if without then waiting for, then quit a program if receive to exit command;
7) after less radio-frequency RFID module for reading and writing 201 receives mobile phone 1 control command that communication management module 202 sends, start the read-write operation of less radio-frequency RFID module for reading and writing 201, read information in the RFID label by the RFID antenna;
8) result is transferred to mobile phone 1 by communication management module 202, turns the 2nd) step.
