In addition, referring to fig. 4 and 5, the present invention further provides a sensing device 1000, where the sensing device 1000 includes the sensing structure 100 described above. It should be noted that, the structure of the sensing structure 100 in the sensing device 1000 may refer to the embodiment of the sensing structure 100 described above, and will not be described herein again; because the sensing detection structure 100 is used in the sensing detection device 1000 provided by the present invention, embodiments of the sensing detection device 1000 provided by the present invention include all technical solutions of all embodiments of the sensing detection structure 100, and the achieved technical effects are identical, and are not described herein.
Further, the sensor detecting device further includes a first signal processing unit 200 and a second signal processing unit 300, the first signal processing unit 200 is electrically connected to the first sensing unit 11 of the sensor detecting structure 100, the second signal processing unit 300 is electrically connected to the second sensing unit 12 of the sensor detecting structure 100, the control device 400 is electrically connected to the first signal processing unit 200 and the second signal processing unit 300, the first signal processing unit 200 is used for controlling the first sensing unit 11 to generate an electric field and reading the electric field change of the first sensing unit 11, and simultaneously transmitting information to the control device 400, the second signal processing unit 300 is used for controlling the second sensing unit 12 to generate an electric field and reading the electric field change of the second sensing unit 12, and simultaneously transmitting information to the control device 400, so that by setting the first signal processing unit 200 and the second signal processing unit 300 to process the first sensing unit 11 and the second sensing unit 12, respectively, the second signal processing unit 300 is prevented from processing the information, and the first signal processing unit 200 is reduced in time delay or the second signal processing unit 300 is greatly processed by the first signal processing unit 200 or the second signal processing unit 300.
The number of the second signal processing units 300 may be one or more, but the present invention is not limited thereto, and since the number of the second sensing units 12 is greater, if only one second signal processing unit 300 is provided, the second signal processing unit 300 needs to process information of a plurality of the second sensing units 12, so that the amount of information processed by the second signal processing unit 300 is too large, which easily results in longer system delay.
The second signal processing unit 300 may be disposed outside the second sensing unit 12 or inside the second sensing unit 12, but the present invention is not limited thereto, and if the second signal processing unit 300 is disposed outside the second sensing unit 12, the wire harness connecting the second signal processing unit 300 and the second sensing unit 12 is longer, and the disturbance of the electromagnetic field generated by the wire harness to the second sensing unit 12 is larger, therefore, in the present embodiment, the second receiving electrodes 122 in one of the second sensing units 12 are disposed in plurality, the second signal processing unit 300 is disposed in the middle of the plurality of second receiving electrodes 122, so that the wire harness length connecting the second signal processing unit 300 and the second sensing unit 12 is reduced, and the influence on the second sensing unit 12 is reduced.
