Furthermore, since the wireless network module 91 and the image processing module 92 are in different technical fields, it is difficult to combine the two modules alone, so it is not easy to expand other functions, so that It is difficult for the known wireless camera device 9 to have multiple functions.

Wherein the application system 2 used by the user only needs to have the function of a wireless network, and then it can be wirelessly connected to the image signal transmission device 1 of the present utility model, and then can receive and obtain the on-site information of the image signal transmission device 1. screen.

Please refer to FIG. 3 , which is a block diagram of an embodiment of the wireless image signal transmission device of the present invention. As shown in the figure, the present invention provides an image signal transmission device 1 , which includes: a control unit 10 , an image acquisition unit 11 , a wireless transceiver unit 12 and an antenna 13 . Wherein, the wireless transceiver unit 12 is a radio frequency-baseband transceiver (RF-Baseband Transceiver), and is electrically connected with the antenna 13, so that the control unit 10 can control the wireless transceiver unit 12 and wirelessly connect with the application system 2 through the antenna 13 .

The image acquisition unit 11 is, for example, a digital image acquisition unit of charge-coupled device type or complementary metal oxide semiconductor type, and is used to acquire image signals at the site where the image signal transmission device 1 is set.

The control unit 10 is electrically connected between the image acquisition unit 11 and the wireless transceiver unit 12, and further includes: a core unit 101, an image processing unit 102, a plurality of first expansion interface units 103 and at least a second expansion interface unit 104 . The first expansion interface unit 103 is used to electrically connect to the image acquisition unit 11 to receive and transmit the image signal collected by the image acquisition unit 11 .

The core unit 101 is a core processing unit in the control unit 10 mainly used for processing wireless network functions, and the core unit 101 is electrically connected to the image processing unit 102 , the first expansion interface unit 103 and the second expansion interface unit 104 . This makes when the core unit 101 receives the image signal through the first expansion interface unit 103, the core unit 101 activates the image processing unit 102 to process the image signal and perform encoding. Afterwards, the core unit 101 converts the image signal processed by the image processing unit 102 into a wireless network standard signal. Finally, the control unit 10 controls the wireless transceiver unit 12 and transmits the signal of the wireless network standard to the application system 2 through the antenna 13 .
