Embodiment 1

[0039] Embodiment 1 of the present invention discloses a cover opening protection device, such as figure 1 or figure 2 As shown, it includes: a metal shrapnel 200, a controller 120; one end of the metal shrapnel 200 is grounded; the other end of the metal shrapnel 200 is used to connect with the controller 120 when the cover is not opened, and when the cover is opened Next interrupt the connection with the controller 120; the controller 120 is used to generate a first signal when the metal dome 200 is connected, and to generate a second signal when the metal dome 200 is not connected; the first A signal is different from the second signal.

[0040] The specific cover opening protection device can protect products with covers or casings such as chips or certain boxes.

[0041] Specifically, in one embodiment, the device is provided with a carrier, that is, the device body 100. The device of this solution is used to judge whether there is a cover, that is, whether the shell c...

Embodiment 2

[0058] In order to further illustrate this solution, Example 2 of the present invention also discloses a cover-opening protection method, which is applied to the cover-opening protection device described in Example 1, such as image 3 As shown, the method includes the following steps:

[0059] Step S101, acquiring historical signals generated by the controller;

[0060] Specifically, for example, the stored historical signals may be acquired from the memory 140 .

[0061] Step S102, if the second signal exists in the historical signals, control to suspend the current scheduled service;

[0062] If there is a second signal, it means that the cover has been opened. In this case, the product protected by the cover open protection device, such as the chip, is in an unsafe state, so the control chip enters the password locked state. Specifically, when the chip enters the password After the locked state, the chip is locked and cannot perform normal business.

[0063] Step S103, i...

Abstract

The embodiment of the invention discloses an uncovering protection device and method. The uncovering protection device comprises a metal elastic piece and a controller. One end of the metal elastic sheet is grounded; the other end of the metal elastic sheet is used for being connected with the controller when the cover is not opened and disconnecting the connection with the controller when the cover is opened; the controller is used for generating a first signal when the controller is connected with the metal elastic sheet and generating a second signal when the controller is not connected with the metal elastic sheet; the first signal is different from the second signal. According to the scheme, the metal elastic piece is arranged, the controller is combined, the metal elastic piece and the controller are switched between the connection state and the disconnection state by means of different pressure on the metal elastic piece when the cover is opened and not opened, and therefore different signals are generated, and whether the cover is opened or not can be judged based on the difference of the signals; therefore, the technical effect of improving the product safety and the use safety is achieved.

Description

technical field [0001] The invention relates to the technical field of chip protection, in particular to a cover opening protection device and method. Background technique [0002] Communication equipment, industrial control equipment, etc. have high requirements for their operation safety. In particular, some communication devices carry public communication needs and have high security requirements, such as data confidentiality and technical confidentiality. Hackers are prohibited from invading the system by various means, stealing data and destroying communication. Therefore, it is required that once the cover is illegally opened, the system operation should be stopped, and an alarm can be realized to lock the system. Currently, the following solutions exist for this need: [0003] For example, a device for detecting light intensity in an environment. The device is soldered on the circuit board of the base station. In the state of opening and closing the cover, the am...
