More than describe an embodiment who has provided electric control system on the computing machine of the present invention, describe the electrification control method of electric control system on the computing machine of the present invention below with reference to Fig. 4.Referring to Fig. 4, electrification control method of the present invention comprises:
Step 1, after embedded controller is triggered, time sequence control device sends authentication request to powering on, the request of electrifying timing sequence control device response authentication sends to embedded controller with authentication information, and embedded controller is carried out authentication according to the authentication information of storing in authentication information that sends and the computing machine;
When the user has triggered the shift knob of computing machine, can send a power-on pulse signal to embedded controller to trigger embedded controller.After embedded controller is triggered, then send authentication request to the time sequence control device that powers on, the electrifying timing sequence control device receives after the authentication request, then with the authentication information stored in the electrifying timing sequence control device (such as (ElectricallyErasable Programmable Read Only Memory is called for short E at Electrically Erasable Read Only Memory
2PROM), flash memory (FLASH, be called for short flash memory) etc. the information such as authentication code of storing in the storage medium) send to embedded controller, embedded controller is judged according to the authentication information of storing in received authentication information and the embedded controller, whether the authentication information of judging two places is consistent, whether with definite this electrifying timing sequence control device is the electrifying timing sequence control device that belongs to this computing machine, and then verifies the legitimacy of this electrifying timing sequence control device.When the authentication information of storing in authentication information that the electrifying timing sequence control device sends and embedded controller is consistent, then by authentication, think that this electrifying timing sequence control device is legal, otherwise authentication is not passed through, think that this electrifying timing sequence control device is illegal, finish power up, return not trigger switch button state of initial user.
Step 2, after by authentication, the electrifying timing sequence acquisition module sends the electrifying timing sequence request to the time sequence control device that powers on, the electrifying timing sequence control device responds the electrifying timing sequence that this request will wherein store and sends to embedded controller, embedded controller receives described electrifying timing sequence and sends it to the power supply of computer system (being the second source module in the computing machine), to carry out power up.
Embedded controller carry out authentication determination electrifying timing sequence control device legal after, then send the electrifying timing sequence request to the time sequence control device that powers on, request electrifying timing sequence control device sends electrifying timing sequence.The electrifying timing sequence control device receives after this request, from the storage electrifying timing sequence medium (such as E
2In the storage medium of PROM, FLASH etc.) obtain electrifying timing sequence, and at interval electric pulse in the electrifying timing sequence that obtains each is sent to embedded controller one by one according to preset time.Embedded controller receives on each after the electric pulse, then gives the second source module with the pulse transmission that powers on that is received, and the appropriate section that the second source module is opened according to last electric pulse is that each hardware of computing machine powers on one by one according to predetermined order.
In the said method, embedded controller is after the electrifying timing sequence sending module sends request, and the electrifying timing sequence control device then will be gone up electric pulse at interval according to preset time and send over successively.Yet, if the electrifying timing sequence acquisition module does not receive one of them pulse, will use wrong pulse signal to carry out so and power on, and the system that will go wrong this moment can't powering on for computing machine, system will be stuck in this process.
For this reason, can also adopt another kind of mode to send described electrifying timing sequence.After the electrifying timing sequence control device receives the electrifying timing sequence request, electric pulse is to described embedded controller in the transmission electrifying timing sequence first, embedded controller gives the power supply of computer system to carry out power up the described pulse transmission that powers on, send the next request signal of going up electric pulse to the time sequence control device that powers on simultaneously, after this after the electrifying timing sequence control device receives the request signal that embedded controller sends, just send the last electric pulse of being asked according to predetermined rule, finish until all pulse transmissions that power on, and confirming not receive under the situation of being scheduled to electric pulse, then stop this power up.Such as, embedded controller can be powering on into after the function signal of obtaining that hardware feeds back, send the next electric pulse request of going up, perhaps can in embedded controller, store the electrifying timing sequence time interval, if utilize the time interval of being stored to judge whether to receive at the fixed time electric pulse, then send electric pulse request on the next one if receive electrifying timing sequence at interval at preset time.So just can be only on formerly electric pulse be under the situation of correct pulse signal, just receive next pulse, so just can avoid responding and be about to that electric pulse sends over the problem that is produced successively on all after the electrifying timing sequence request.Fingerprint authentication mode of the prior art is compared, and directly powers on after by fingerprint authentication, and power up is not controlled, and therefore, it will be safer adopting the electrification control method of this mode.
By said method, described embedded controller just can obtain electrifying timing sequence from external electrifying timing sequence control device, thereby finishes the power up of system.By controlling the mode of electrifying timing sequence, when starting shooting, just can normally power on for computing machine with regard to the feasible electrifying timing sequence control device that only passes through to authenticate in use.Even computing machine is illegally pried open,, still can't not open computer with the electrifying timing sequence control device of this computing machine coupling., compare with the secured fashion of prior art for this reason, system and method for the present invention, more safe and reliable.In addition, carry out in the process of data transmission at electrifying timing sequence control device and computer system, can also encrypt the authentication information that embedded controller sends to the electrifying timing sequence control device, described embedded controller is then verified described authentication information according to predetermined rule deciphering back, further to guarantee security.
In addition, when first power module in the electrifying timing sequence control device adopts the battery mode to power, can adopt wireless mode to carry out communication between described electrifying timing sequence control device and the computing machine, carry out communication such as adopting infrared technology or Bluetooth technology, can certainly adopt wired mode to carry out communication, such as by transmission line, perhaps, transmit directly with the mode of first interface and the grafting of second interface.And when employing provides power by first interface and second interface for it by computing machine, then can only adopt wired mode to carry out communication.
Embodiment described above most preferred embodiment all of the present invention, these embodiment are in order to explain the present invention better, are any limitation of the invention and should not be construed as.Under the situation that does not depart from thought of the present invention and spirit, those skilled in the art can design multiple substituting and modification, yet these substitute and modification does not all exceed claimed scope of the present invention.
