example 1

[0098] As shown in Figure 6(a), the charge sensing element includes the antennas at the four corners of the terminal. When the terminals are all placed on the table, since all the projected areas of the antennas at the four corners of the terminal are on the table, the charge collection circuit will detect a If the induced charge value is relatively large, and the induced charge value is the same as the induced charge value corresponding to the pre-stored desktop material property, it can be determined that the terminal is safely placed on the desktop.

[0099] As shown in Figure 6(b), if the induced charge value detected by a certain charge sensing element at the bottom of the terminal is very small, such as 1fF, the system will automatically adjust the amplification gain to detect its distance to the ground. If the distance to the ground is greater than A preset threshold, such as 0.5 meters, can determine that the bottom of the current terminal is placed in the air.

example 2

[0101] Such as Figure 7 As shown, when the terminal is placed on the human hand, the induced charge values ​​of the three areas A, B, and C are obtained, and it is judged that the terminal is in contact with the human hand in the three areas A, B, and C, and it can be identified that the terminal is in the normal hand-holding range. The detection terminal is placed in the user's hand, and it is judged that the terminal is in a stable and safe state at three points.

[0102] If the terminal is moved in the human hand, becomes Figure 8 In the position shown, at this time, it is detected that the induced charge value in area A is the same as the induced charge value corresponding to the pre-stored air medium, which is not a human hand, while areas B and C are still in the human hand. It is judged that the upper left side of the terminal is out of the range of the hand grip. It does not belong to the three-point stable state, and an alarm can be sent at this time.

example 3

[0104] Such as Figure 9 As shown, in this embodiment, when it is judged that the terminal is in a free fall state, the distance between the terminal and the ground is detected, and when the changes of the induced charge values ​​of the charge sensing elements located at the four corners of the terminal are relatively equal values, it is judged that the terminal has landed horizontally .

Abstract

The invention discloses a state detection device and method. The state detection device comprises: one or more charge sensing elements arranged on the terminal, a charge acquisition circuit connectedwith the charge sensing elements., and a detection module connected with the charge acquisition circuit; the charge collection circuit generates charges which are radiated through the charge inductionelements, collects the charges reflected by each charge sensing elements to generate a sensing charge value of the charge induction element, and outputs the sensing charge value of each charge sensing element to the state detection module. The state detection module determines the state of the terminal according to the sensing charge value. According to the scheme provided by the invention, the state of the terminal is detected through the sensing charge value, and detection of the terminal in a static state can be realized.

Description

technical field [0001] The invention relates to terminal technology, in particular to a state detection device and method. Background technique [0002] Nowadays, the use scenarios of mobile terminals are becoming more and more complex, and the industry and users have higher and higher requirements for the intelligent performance of terminals. In related technologies, generally, an acceleration sensor, a gravity sensor, a gyroscope, etc. are used to detect a terminal state. Therefore, usually only the terminals in the moving state can be detected, and the terminals in the stationary state cannot be detected. Contents of the invention [0003] At least one embodiment of the present invention provides a state detection device and method to realize terminal state detection. [0004] In order to achieve the purpose of the present invention, at least one embodiment of the present invention provides a state detection device, including: one or more charge sensing elements arran...
