[0057] Specifically, the first relay module includes multiple relays, and the relays of the first relay module correspond one-to-one to the polling deserializer. By controlling the corresponding relays to close, the data output by the polling deserializer can be controlled to be transmitted to the serializer polling module. The models of each polling deserializer are different. When the output end of the polling deserializer outputs a high level, it is determined that the model of the polling deserializer matches the model of the serializer in the camera.

[0062] In one embodiment of the present application, Figure 1 As shown, the polling adapter 300 further includes a first image signal processing module 340, which is electrically connected between the deserializer polling module 310 and the serializer polling module 320, and is used to convert the format of the video data output by the deserializer polling module 310 into a video format.

[0063] Specifically, the first image signal processing module can implement the function of the ISP module when the ISP module is not integrated in the camera.

[0064] In one embodiment of the present application, Figure 1 As shown, the first image signal processing module 340 includes:

[0067] Specifically, the third relay module only needs to include one relay. When the output end of the first image signal processing module outputs a high level, it is determined that the first image signal processing module realizes the function that the ISP module in the camera should realize, and the third relay module is turned on to realize the subsequent data transmission.

[0068] In one embodiment of the present application, Figure 1As shown, the polling adapter 300 further includes a second image signal processing module 350, which is electrically connected between the serializer polling module 320 and the data acquisition device 200, and is used for converting the format of the second serialized data output by the serializer polling module 320 into a video format.

[0069] Specifically, the second image signal processing module can implement the function of the ISP module when the ISP module is not integrated in the data acquisition device.

[0075] Specifically, the indicator light will be emitted only when the indicator structure is turned on, and may be a strobe indicator light, to remind the staff that the data from the camera has been transmitted to the data acquisition device.

[0076] In one embodiment of the present application, the transistor control structure is a Darlington transistor matrix.

[0077] Specifically, the model of the transistor control structure is ULN2803A, so that it is possible to control whether the device is turned on or not according to the high level or low level outputted by the output terminal of the device.

[0079] The existing technology can only achieve the adaptation of data acquisition equipment to fixed models of cameras. If it is necessary to communicate with other models of cameras, the deserialization chip and hardware circuit of the data acquisition equipment need to be replaced. However, when the deserialization circuit has been integrated with the basic function circuit board, replacing the deserialization circuit requires replacing the entire circuit board, which is almost equivalent to replacing the data acquisition device. The proposed polling data transmission system can achieve the adaptation of multiple models of cameras without replacing the hardware of the data acquisition device.

[0080] It should be noted that the above electrical connection can be a direct electrical connection or an indirect electrical connection. Direct electrical connection means that two devices are directly connected, and indirect electrical connection means that other devices such as capacitors and resistors are also connected between the connected A and B.

In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
