The utility model provides an electrostatic detection device.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of the electrostatic detection apparatus of the present invention; fig. 2 is a schematic structural diagram of another embodiment of the electrostatic detection apparatus of the present invention.
In the embodiment of the present invention, the static electricity detection apparatus includes a signal detection module 100, a signal conversion module 200, and a storage module 300. The output end of the signal detection module 100 is connected to the input end of the signal conversion module 200, and the input end of the storage module 300 is electrically connected to the output end of the signal conversion module 200. The signal detection module 100 includes a static electricity detection unit 110 for detecting static electricity in a signal of a device to be detected, for example, detecting static electricity in a television signal of a television. The signal conversion module 200 is configured to convert the electrostatic signal detected by the electrostatic detection unit 110 into a storage signal. The storage module 300 is configured to store the storage signal.
Specifically, in the present embodiment, the signal detection module 100 may have many forms, and any form can detect the static condition in the signal. It is exemplified that the signal detection module 100 includes a static electricity detection unit 110 for detecting static electricity in a signal of the device to be detected. Of course, the signal detection module 100 further includes a signal input unit 120 and a signal output unit 130, the signal output unit 130 and the static electricity detection unit 110 are both electrically connected to the signal input unit 120, and the static electricity detection unit 110 is electrically connected to the signal conversion module 200. The signal input unit 120 has a signal input terminal to which an input port and/or an output port (e.g., a multi-HDMI input terminal, a multi-USB input terminal, a high definition signal input terminal, an AV signal output terminal, etc.) of a device to be tested is connected. The signal output unit 130 has a signal output terminal connected to the signal input terminal. The static electricity detection unit 110 is configured to detect static electricity in the input signal acquired by the signal input unit 120. The signal output unit 130 has a signal output terminal corresponding to the signal input unit 120 to output a signal entering the signal input unit 120 to the signal detection module 100. The static electricity detection unit 110 receives the signal input by the signal input unit 120, performs static electricity detection on the received signal, and transmits the detection result to the signal conversion module 200 in the form of a static electricity signal.
In this embodiment, the device to be detected is exemplified by a television, and the signal input terminal of the signal input unit 120 is connected to the input port and the output port of the television, so that all input and output signals of the television enter the signal detection module 100 through the signal input unit 120. The static electricity detection device in this embodiment may be integrated inside the television, or may be disposed outside the television. Taking the example that the scenery spot detection device is disposed outside the television, when the signal input terminal of the signal input unit 120 is connected to the input port of the television, the static electricity detection device is disposed between the television and the signal source for inputting signals to the television; when the signal input terminal of the signal input unit 120 is connected to the output port of the television set, the television set itself serves as a signal source, and a signal (static electricity detection means) is output to other devices (for example, a display apparatus for receiving an output signal of the television set) through the signal output unit 130.
The signal conversion module 200 functions to convert the electrostatic signal of the detection unit 110 into a storage signal that can be stored. The signal conversion module 200 may have many forms, and in this embodiment, the signal conversion module 200 has a positive esd output circuit 210 and a negative esd output circuit 220 connected in parallel. The positive esd output logic 210 and the negative esd output logic 220 convert the high esd voltages to low logic levels for storage in the memory module 300. The high electrostatic voltage is an electrostatic signal output by the electrostatic detection unit 110, and the low logic level is a storage signal converted by the conversion module. Of course, in some embodiments, the signal conversion module 200 may also first reduce the static voltage to a low voltage, such as 3.3V (volt) for output, and then convert the low voltage into a logic level that can be stored by another controller. The voltage conversion logic output circuit can be implemented by a voltage conversion circuit such as an integrating circuit and an MOS transistor switching circuit, which is not described herein again.
Of course, in some embodiments, in order to make the structure of the static electricity detection apparatus more compact and the volume thereof smaller, the signal conversion module 200 and the static electricity detection unit 110 are disposed on the same circuit board.
In this embodiment, the signal detection module 100 detects the static condition in the signal of the device to be detected, and the signal conversion module 200 converts the static signal output by the signal detection module 100 into a storage signal which can be stored by the storage module 300, and the storage module 300 stores the static condition in the signal of the device to be detected in the storage of the storage signal, which is beneficial for a user to retrieve data for analysis in the later research so as to know the reason of the chip damaged by the static.
Further, referring to fig. 1 and 2, the static electricity detecting unit 110 includes a tip discharge element 111, and the tip discharge element 111 has a first electrode and a second electrode forming a discharge gap 112. The first electrode is electrically connected to the signal input unit 120, and the second electrode is electrically connected to the signal conversion module 200. The pitch of the discharge gap 112 is positively correlated to the electrostatic discharge voltage. The number of the point discharge elements 111 may be multiple, and the discharge gaps 112 of each of the point discharge elements 111 are linearly spaced.
Specifically, in the present embodiment, the detection of static electricity by the static electricity detection unit 110 is realized by a form of a tip discharge. The first electrode and the second electrode of the point discharge element 111 are both metal electrodes, and in this embodiment, the discharge gap 112 is preferably formed by a metal copper foil of a PCB, the first electrode and the second electrode have oppositely disposed electrode points, and a gap between the two electrode points forms the discharge gap 112. The size of the discharge gap 112 corresponds to a discharge voltage of the tip discharge, i.e., corresponds to an electrostatic discharge voltage. The electrostatic discharge voltage increases with increasing discharge gap 112, such as a discharge gap 112 distance of 0.1mm (millimeters) for an electrostatic voltage of 500V, 0.2mm for an electrostatic voltage of 1000V, and so on. Different electrostatic discharge voltages can correspond to different signals, and different signals come from different parts of the television, so that the source of static electricity can be judged according to different electrostatic discharge voltages, and whether the signals output by different parts of the television have static electricity or not can be judged. Therefore, it is possible to detect different electrostatic discharge voltages by providing a plurality of sets of the electrostatic detection unit 110 (different discharge gaps 112 of the included tip discharge elements 111) and the signal conversion module 200.
The following describes a specific embodiment of detecting different electrostatic discharge voltages by setting a plurality of sets of the electrostatic detection units 110 (including different discharge gaps 112 of the tip discharge elements 111) and the signal conversion module 200. In this embodiment, the discharge gaps 112 between the different tip discharge elements 111 are sequentially arranged from small to large, that is, as described above, the distances between the discharge gaps 112 are linearly distributed, and the distances between all the discharge gaps 112 are on the same straight line or curved line. As shown in fig. 2, the signal line 700 transmits all signals received by the signal input unit 120, the discharge gaps 112 of the plurality of tip discharge elements 111 gradually increase from left to right (which indicates that the electrostatic discharge voltage gradually increases from left to right), all the first electrodes are connected to the signal line 700, and each of the second electrodes is respectively connected to a different signal conversion module 200, that is, each tip discharge element 111 corresponds to a set of voltage conversion logic output circuits (including the positive voltage conversion logic output circuit 210 and the negative voltage conversion logic output circuit 220). Each voltage conversion logic output circuit stores the converted level signal to a different location of the memory module 300.
In the memory module 300, different logic level signals are stored at different positions according to different positions of electrostatic discharge (different output positions of corresponding voltage conversion logic output circuits), so that different signal sources are judged according to different storage positions, and further, parts generating the signals are traced. The distance between the discharge gaps 112 of the point discharge element 111 is linearly arranged, so that the electrostatic detection device can more accurately detect the electrostatic condition in the signal of the equipment to be detected, and better follow-up research is facilitated.
