Embodiment 1

[0054] see figure 1 , is a flow chart of Embodiment 1 of the hard disk protection of the present invention. include:

[0055] Step 101: Send a specific first frequency f to the outside world through the ultrasonic transceiver on the terminal 1 Ultrasonic wave, and record the emission time t 1 ;

[0056] The outside world here may be various directions outside the terminal, for example, sending ultrasonic waves above the terminal.

[0057] Step 102: Immediately reflect the ultrasonic wave after encountering an object during the controlled propagation process;

[0058] Step 103: The ultrasonic transceiver receives the reflected ultrasonic wave, and recognizes that its frequency is the second frequency f 2 , and record the moment t when the reflected ultrasonic wave is received 2 ;

[0059] Step 104: Calculate the distance s between the object and the terminal by using the propagation speed of the ultrasonic wave and the time interval between receiving the ultrasonic wave ...

Embodiment 2

[0077] The difference from the first embodiment is that this embodiment uses another way to calculate the moving speed of the object. In a nutshell, by transmitting and receiving ultrasonic waves multiple times, using the distance difference and time interval difference between the two processes, the moving speed is calculated.

[0078] see figure 2 , is the schematic diagram of the second embodiment.

[0079] in:

[0080] the s 1 It is the first time to transmit and receive ultrasonic waves to calculate the distance between the object and the terminal;

[0081] the s 2 It is the second time to transmit and receive ultrasonic waves to calculate the distance between the object and the terminal

[0082] the s 1 and s 2 The specific calculation method is the same as that in Embodiment 1.

[0083] Therefore, within the time of transmitting ultrasonic waves twice, the moving distance of the object is: Δs=s 1 -s 2 ;

[0084] t 11 , t 12 Respectively, the two moments of...

Embodiment 3

[0090] Both of the above two embodiments adopt an idea, that is, firstly determine whether the object is within the distance threshold, and then determine whether the moving speed of the object reaches the speed threshold, and then decide whether to perform a suspend operation on the hard disk.

[0091] Different from the above idea, this embodiment first determines and judges the moving speed of the object, if it exceeds the speed threshold, then determines whether the object is within the distance threshold, and if so, performs a suspend operation on the hard disk.

[0092] Alternatively, the moving speed of the object and the distance of the object may be considered at the same time, that is, proportional factors are assigned to the moving speed and the distance of the object respectively. For example, there may be such a situation, although neither the moving speed nor the distance of the object reaches the threshold value, but after considering both, it is necessary to exe...

Abstract

The invention discloses a method for controlling terminal automatically, which includes the following steps: an induction device is installed in the terminal; the operation of the terminal parts is controlled automatically when the induction device detects special object within the range of prearrange distance. By using the method, the harddisk can be comprehensively protected and the power consumption of the peripherals such as keyboard or mouse can be saved, moreover, automatic startup or shutdown of the terminal, automatic forwarding and backwarding of the browser, and automatic turn-page of the application software can be realized. Corresponding to the method, the invention also includes a terminal control system and a terminal installed the control system.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method and system for automatically controlling a terminal and a terminal installed with the above system. Background technique [0002] Active Protection System (Active Protection System, APS) is a commonly used hard disk protection technology. It is proposed for hard disk damage and data loss caused by laptops falling easily. It can prevent sudden acceleration and other movements in advance, and will The input and read heads of the laptop's hard drive are closed until the laptop is stable, similar to a car's airbag to reduce impact, so this feature is called "airbag" technology for laptops. [0003] Specifically, the APS hard disk protection technology is composed of an acceleration sensing chip embedded on the motherboard and a vibration prediction management software pre-installed in the system. By monitoring the angle, vibration, and impact of the notebook (that...
