Fig. 5 is a schematic structural diagram of a sensing control system according to an embodiment of the present application. The sensing control system 4 comprises a sensing element 410, and a control module 420 comprising a sensing control module 421 and a central control module 422.

The sensing control module 421 is used for generating a scanning signal provided to the sensing element 410, receiving a sensing signal generated by the corresponding scanning signal, and providing a sensing result according to the sensing signal. In an embodiment, the sensing control module 421 is a capacitive sensing chip, and the application is not limited thereto.

The central control module 422 is electrically connected to the sensing control module 421, and is configured to receive the sensing result and determine whether to control an electrically connected component 5 or perform a corresponding operation according to the sensing result. For example, the central control module 422 determines whether a sensing event occurs according to the sensing result, and the central control module 422 determines that a sensing event occurs, so as to control the component 5. In one embodiment, the central control module 422 is a control circuit, and the application is not limited thereto.

In one embodiment, the sensing element 410 may be disposed in an electronic device such as a smart phone, and the central control module 422 may perform corresponding operations according to the sensing result. For example, when the central control module 422 determines that a sensing event occurs, the central control module 422 causes the smart phone to display a locked state screen.

In one embodiment, the component 5 is, for example, a bluetooth communication module. Therefore, in this embodiment, the central control module 422 can control the bluetooth communication module to perform corresponding operations according to the sensing result. For example, the central control module 422 determines that a sensing event occurs, and the central control module 422 enables the bluetooth communication module to send a signal and establish a communication connection with an electronic device, such as a smart phone, which is not limited by the present disclosure.

In one embodiment, the element 5 is, for example, a heating fabric, which comprises at least one resistive element. Therefore, in this embodiment, the central control module 422 can control the heating fabric to be heated according to the sensing result. For example, the central control module 422 determines that a sensing event occurs, and the central control module 422 can provide current to the resistive elements in the heating fabric, so that the resistive elements start to increase in temperature by the current flowing through the resistive elements, so as to start heating the heating fabric.

In one embodiment, the sensing and control system 4 may be configured in a smart fabric, and the application is not limited thereto. As shown in fig. 6, the sensing element 410 may be disposed on the smart fabric 6 near the arm or the palm, and electrically connected to the control module 420 through a communication yarn or other conductive wires, so that the user can conveniently perform the above-mentioned different operations (for example, the smart fabric starts heating up and heating up by sensing with the sensing element 410 and controlling the heating fabric) by touching or approaching the sensing element with the finger or the palm, and the application is not limited to the above-mentioned operations.

In one embodiment, to avoid the occurrence of an event that the sensing element 410 is touched by mistake and causes the sensing control system 4 to perform a corresponding operation, the central control module 422 continuously determines that the sensing event occurs, and after the time for continuously determining that the sensing event occurs exceeds 3 seconds, the central control module 422 controls the element 5 or performs a corresponding operation to ensure that the sensing control system 4 operates correctly according to the operation of the user, wherein the 3 seconds is merely an example, and the number of seconds is not limited in the present application.

In summary, since the sensing element of the embodiment of the present application can be completed by only the communication yarn and the single core wire, the manufacturing complexity and the overall volume of the sensing element are greatly reduced. In addition, the signal yarn has better anti-pulling capability, so the sensing element can be configured on a flexible material, the application range of the sensing element is greatly improved, and the sensing element can be flexibly configured, so the commercial value and the use convenience of the sensing element are further improved.

The above description is only an example of the present application, and is not intended to limit the scope of the present application.
