Accompanying drawing explanation
Fig. 1 is the illustrative view of functional configuration of the start-up control device based on NFC that the embodiment of the present invention provides;
Fig. 2 is the start control principle schematic diagram that the embodiment of the present invention provides.
The realization of the object of the invention, functional characteristics and excellent effect, be described further below in conjunction with specific embodiment and accompanying drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
In order to realize the present invention, need in portable terminal device software, set NFC start controlling functions menu.Before entering this menu, user needs corresponding authentication.Start shooting in controlling functions menu at this NFC, provide and control relevant all functions option to starting shooting.As opened NFC start controlling functions, POS identifying code sets, TAG identifying code setting etc.After completing corresponding menu setting, system can according to the passage of the content configuration starting-up signal POWER_ON arranged.If open NFC start controlling functions, POWER_ON signal will be controlled by the NFC chip of portable terminal device, now cannot be started shooting by the starting key of system, thus achieves start control.When the portable terminal device as POS terminal is near this equipment, NFC chip is started working, and after simple information interaction, as TAG identifying code meets, then controls to export starting-up signal, completes start.In addition, in certain embodiments, after powering, system is also wanted regularly and POS terminal carries out information interaction, and not so system will be restarted.
In detail, a kind of start-up control method based on NFC that the embodiment of the present invention provides, comprises following concrete steps:
S101, open NFC start shooting the TAG terminal of controlling functions close to POS terminal time, POS terminal sets up the NFC information interaction passage with TAG terminal, and send corresponding TAG identifying code to TAG terminal, wherein, described POS terminal is by the pre-configured TAG identifying code of its property value as POS terminal attribute and TAG terminal to be controlled of software, and described TAG terminal is by software pre-configured its property value as TAG terminal attribute and unique reference TAG identifying code;
The TAG identifying code of acquisition and the reference TAG identifying code pre-set are compared by S102, TAG terminal, if identical, then perform power-on operation.
Under preferred implementation; before user starts shooting controlling functions by the NFC of software unlatching TAG terminal; also need to carry out authentication, thus allow legal user carry out the setting of other functions such as NFC start controlling functions, and then better protect the information security of user.
Under preferred implementation, the TAG identifying code of acquisition and the reference TAG identifying code pre-set are compared by TAG terminal, and after performing power-on operation, also comprise the steps:
If S103 TAG terminal opens timing function of swiping card by software, then TAG terminal detects the NFC signal of POS terminal periodically in the timing preset, when detecting, read corresponding TAG identifying code from POS terminal and itself and the reference TAG identifying code pre-set are compared, if identical, then timer and the NFC chip position in order to stored reference TAG identifying code is emptied, if not identical, then perform power-off operation.
The present embodiment is for certain intelligent mobile phone platform, and corresponding NFC chip is the PN544 of NXP (En Zhi Pu semiconductor company).As shown in Figure 1, system is selected module 20 to switch NFC module 10 by switch control rule to start shooting with starting key 50.By menu option corresponding in processor A P module 30 control system, can gauge tap control to select module 20 to be switched to corresponding switching channels, the power_on signal like this by dragging down power management PMU module 40 just can realize start.Concrete switch control rule selects the realization of module 20 to have a lot of mode, can with reference to example of the present invention, as shown in Figure 2, described switch control rule selects module 20 to comprise SR latch 200 and selector switch 201, described processor A P module 30 is connected with two input ends of SR latch 200 by two universal input/output GPIO interfaces, for starting shooting according to the NFC generated, controlling functions open command control SR latch 200 exports open channel switching command to selector switch 201, effectively switch to NFC module 10 effective with the open channel of just power management PMU module 40 by starting key 50.
In this embodiment, the function using SR latch 200 and 2 to select 1 selector switch 201 can realize system power failure on off state to keep.It should be noted that, switch control rule selects module 20 to be to use standby electricity battery-powered, power down after not worrying shutting down.Briefly, after arranging corresponding menu function, processor A P module 30 exports corresponding state by two I/O GPIO interfaces and switches open channel with control SR latch 200 output control selector switch 201.When after system closedown power down, the I/O GPIO interface of processor A P module 30 is low level, makes the output that SR latch 200 keeps original, reaches with this object controlling open channel.
In specific implementation process, need to develop corresponding function menu in mobile phone interface.For android mobile phone, can under Configuration Position and safe vegetable individual event, the configuration of newly-increased new menu NFC start controlling functions.In layoutprocedure, when entering this menu, need password authentification, user is correct, and input validation password just can enter.
Under this function menu, mainly contain change of secret code, NFC switch control functions On/Off menu, after opening NFC switch control functions, there will be TAG terminal configuration, POS terminal configuration menu, these two menus are mutual exclusions, can only arrange one simultaneously.The property value of TAG terminal attribute or the property value as POS terminal attribute can be provided as by described TAG terminal configuration or POS terminal configuration.
After TAG terminal attribute value or POS terminal property value are set, can only just achieve NFC start controlling functions by mobile phone.It should be noted that for TAG terminal to only have and be correctly provided with TAG terminal attribute value and be correctly provided with TAG identifying code, just can only can control to switch start hardware corridor by mobile phone, prevent the situation of open channel confusion.In order to the situation preventing TAG terminal from not shutting down always, can select to open timing function of swiping card by software.After opening this timing function of swiping card, TAG terminal must brush POS terminal (by TAG terminal near POS terminal) in the timing of regulation, and not so system will be shut down.During concrete enforcement, for TAG terminal, system can read the specific region of NFC chip after the timing of regulation arrives, and is contrasted by the identifying code of the value read and setting, the position that timer and NFC module 10 store identifying code empties by equal words, and the words do not waited will be shut down.
After TAG terminal closedown, then start will be reentered when starting shooting judge flow process, after satisfied, just can enter normal boot-strap flow process.When TAG terminal near POS terminal time, the NFC module 10 of TAG terminal will be started working, and briefly, after POS terminal detects TAG terminal, TAG identifying code can be written to the specific region of TAG terminal.TAG terminal, after receiving TAG identifying code, can judge that whether this TAG identifying code is consistent, consistent with the reference TAG identifying code pre-set, will control to drag down power_on, thus make this TAG terminal enter starting procedure; Inconsistent, system will be hung up, and boot failure returns.
