Embodiment
In order to enable object of the present invention, characteristic sum effect becomes apparent more, elaborates to the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from mode described here to implement, therefore the present invention is not by the restriction of following public specific embodiment.
A kind of electron device 1 as described in Figure 1, comprises storer 2.
Compared to prior art, the storer 2 of the application comprises the first storage area 10 and the second storage area 11.Wherein, described first storage area 10 is for storage tags data, and described second storage area 11 is for storing conventional data.
The storage area of the application to storer 2 is expanded, and utilizes described first storage area 10 to instead of the storage area of the radio-frequency (RF) tag of prior art electron device.Described label data refers to the data that the storage area of radio-frequency (RF) tag stores, and described conventional data is the data except described label data.
Be different from the storer of prior art electron device:
The memory storage device information (can be the exclusive identification code of described equipment) of prior art and the information except facility information, and the storage area of prior art electron device radio-frequency (RF) tag also stores described facility information; The storage area of described storer 2 is expanded by the application, described electron device does not need to possess radio-frequency (RF) tag, and now, compared to prior art, the storage area of storer 2 is expanded, but the first storage area 10 is for storage tags data, the second storage area 11 does not then need the data that repeated storage is corresponding with described label data or repeat again, and only needs to store the data except described label data.
In specifically arranging, second storage area 11 can be based on the first storage area 10 expand the storage area obtained, also can be with except described first storage area 10, with the extension storage region of the integrated extra setting of the first storage area 10, the structural relation that the application gives tacit consent to the first storage area 10 and the second storage area 11 is for the former.Label data is generally write by the device except described storer and supply the data that the device except described storer conducts interviews, and it generally has unalterable feature.Described conventional data is then write and the data freely can read and write by the device except described storer by the device except described storer.There is between the label data that first storage area 10 stores and the conventional data that the second storage area 11 stores the independence of data content.
The expansion of electron device 1 storage area and the independence stored between data, can strengthen the interaction capabilities of electron device 1 and external unit well:
Based on the first storage area 10, electron device 1 has good near field communications capability, and due to the uniqueness of label data, label data comprises described facility information, and only label data possesses described facility information, can not there is to match with facility information in electron device 1 communication process wrong problem;
Based on the second storage area 11, electron device 1 has good storage capacity, and based on near-field communication mode, the fast access of conventional data can be realized, independence between conventional data and label data, also can make data communication have more object guidance quality, thus have good security performance.
Contact access can be carried out respectively to the first storage area 10 and the second storage area 11 in electron device 1 inside of the application, and the first storage area 10 and the second storage area 11 also can carry out contact and contactless access with external devices.This is specifically realized by the contact interface of storer 2 and the non-contact interface of described storer 2.
Based on Fig. 2, electron device 1 comprises:
Antenna 100;
Radio frequency interface 101;
Radio-frequency (RF) digital control module 102; And,
Contact digital control unit 202.
Wherein, radio frequency interface 101 belongs to non-contact interface, it can carry out contactless to be connected and alternately, described external devices can think the external reader that can carry out read-write operation to the first storage area 10 according to the noncontact field of external devices (i.e. external devices produce electromagnetic field) and external devices.
Described radio-frequency (RF) digital control module 102 for realizing the parsing of radio frequency interface 101 message transfer and the message based on described radio frequency interface 101 transmission, and realizes data interaction with described first storage area 10 or the second storage area 11.
Because the data between the first storage area 10 and the second storage area 11 have independence, now, can seek the destination address that above-mentioned storage area carries out in message that read operation then only needs to be transmitted by external devices based on radio frequency interface 101; But when writing label data or conventional data, the position looking for corresponding first storage area 10 or the second storage area 11 is then based on such as under type:
For the unfixed storer in position of the first storage area 10 and the second storage area 11, then the destination address in the message transmitted by external devices is only needed to locate;
For the storer that the position of the first storage area 10 and the second storage area 11 is fixing, then need when receiving the message that external devices is transmitted, destination address based on this message carries out address discrimination, if this address is in described first storage area or the second storage area, then by first storage area being positioned to correspondence of this message or the second storage area.
Except above-mentioned locator meams, also need to carry out discrimination to the data type of write data: if the write data being resolved to described message belong to label data, then only can enter described first storage area; If the write data of the message be resolved to are the data except described label data, can think described conventional data, then this conventional data only can enter described second storage area.
The process of above-mentioned message location and discrimination performs by radio-frequency (RF) digital control module 102.Based on radio-frequency (RF) digital control module 102, electron device 1 possesses contactless interaction capabilities,
Based on contact communication bus and external devices or electron device 1 inside, the device except described storer carries out alternately contact digital control unit 202.Based on contact digital control unit 202, electron device 1 possesses contact interaction capabilities, and described contact digital control unit 202 can realize realizing data interaction to the parsing of described contact communication bus institute message transfer and the message transmitted based on described contact communication bus and described first storage area 10 or the second storage area 11.Same, contact digital control unit 202 also can realize the process of described message location and discrimination.
