[0034] Embodiment 1

[0037] a host end 200, which has a second connecting structure 201;

[0038] The accessory end 100 and the host end 200 are connected through the first connecting structure 103 and the second connecting structure 201 to realize the hot plug function, and when the first connecting structure 103 and the second connecting structure 201 are connected, the serial data is transmitted to the host end 200 through the first connecting structure 103 and the second connecting structure 201, the host end 200 receives the serial data and deserializes the serial data to regenerate the first data and the second data in parallel.

[0039] In the embodiment, the accessory end 100 further comprises:

[0040] an accessory, which is used to output the first data and the second data in parallel;

[0041] a serializer 104, which is connected to the accessory and the first connecting structure 103 respectively, is used to receive the first data and the second data and serialize the first data and the second data to generate serial data, for example, in the embodiment, the serial data can be a LVDS (Low Voltage Differential Signaling) signal, at the same time, the serializer 104 comprises a MAX9295AGTJ / V+T serializer and the like, which can complete the input of parallel data and the output of serial data through SIOP pins, SION pins and the like;

[0042] At the same time, the first connecting structure 103 comprises a POGO PIN male or female seat.

[0043] The accessory comprises:

[0044] a first accessory 101, which is used to output the first data and the second data in parallel;

[0045] or a second accessory 102, which is used to output the first data and the second data in parallel;

[0046] or the first accessory 101 and the second accessory 102 correspond to output the first data and the second data respectively, and the first data and the second data are in parallel;

[0047] Further, the first accessory 101 and the second accessory 102 are respectively an infrared detector and a visible light detector, and the first data and the second data are respectively infrared image data and visible light image data.

[0048] The host 200 further comprises:

[0049] a deserializer 202 connected to the second connecting structure 201, which is configured to receive the serial data when the first connecting structure 103 and the second connecting structure 201 are connected, and perform deserialization on the serial data to regenerate the parallel first data and second data;

[0050] and a host unit 203 connected to the deserializer 202, which is configured to receive the regenerated parallel first data and second data, process the first data and the second data, and display the processing result;

[0051] In this embodiment, the deserializer 202 comprises a MAX9296AGTM / V+T deserializer, and when the first connecting structure 103 and the second connecting structure 201 are connected, the deserializer 202 can receive the serial data through SIOAP pins, SIOAN pins, SIOBP pins, SIOBN pins, etc., perform deserialization on the serial data, and output the generated first data and second data to the host unit 203 through DA*N pins, DA*P pins, DB*N pins, DB*P pins, etc.; the host unit 203 comprises a SoC host board.

[0052] Meanwhile, the second connecting structure 201 comprises a POGO PIN female seat or a male head matched with the first connecting structure 103.

[0053] Further, when the first connecting structure 103 and the second connecting structure 201 are connected, the serial data can be transmitted to the deserializer 202 through the first connecting structure 103 and the second connecting structure 201 based on a GMSL protocol, and the GMSL protocol supports different transmission rates such as 3Gbps, 6Gbps, and 12Gbps, which can be configured according to actual needs.

[0054] Thus, in the embodiment, the parallel data is first converted into serial data by the serializer, and then transmitted to the deserializer through the connection structure for deserialization, so that the number of signal interfaces is less. Meanwhile, the connection mode of the accessory end and the host end is improved from the traditional coaxial line or twisted pair connection form to the POGO PIN connection mode. The signal transmission between the deserializer and the serializer is realized by mechanical connection, and the pluggable degree is higher. Thus, the accessory end can be hot-plugged without power-off, which is convenient for subsequent maintenance and replacement of the corresponding accessories. The embodiment is more suitable for compact and portable products.

[0055] Embodiment 2

[0056] The difference between the embodiment and the embodiment 1 is that the accessory end 100 further includes:

[0057] A power supply control unit 105 connected to the first connection structure 103, which is used to generate a connection signal when the first connection structure 103 and the second connection structure 201 are connected, and transmit the connection signal to the host end 200. The host control unit 203 of the host end 200 controls the power supply to supply power to the accessory end 100 according to the connection signal, so that the accessory end 100 starts to work.

[0058] The host end 200 further includes:

[0059] An analog-to-digital conversion unit 204 connected to the second connection structure 201 and the host control unit 203 (for example, the host control unit 203 can be connected through an I2C bus or the like), which is used to convert the connection signal into a digital power supply signal when the first connection structure 103 and the second connection structure 201 are connected.

[0060] The host control unit 203 receives the digital power supply signal, and controls the power supply to supply power to the accessory end 100 according to the digital power supply signal, so that the accessory end 100 starts to work.

[0061] For example, in the embodiment, as shown in Figure 2As shown, the power supply control unit 105 includes a resistor R1, one end of which is suspended when the first connection structure 103 and the second connection structure 201 are not connected, and the other end is connected to the digital ground DGND, at which time no connection signal is generated. When the first connection structure 103 and the second connection structure 201 are connected, a connection signal Pog_IN is generated, and the voltage of the connection signal Pog_IN is pulled down to 0V. At the same time, the connection signal Pog_IN is transmitted to the analog-to-digital conversion unit 204 through the second connection structure 201, and is converted into a digital power supply signal by the analog-to-digital conversion unit 204 and sent to the host control unit 203. The host control unit 203 controls the power supply VDD_5V0 to supply power to the accessory end 100 according to the digital power supply signal, and the accessory end 100 starts to work, which includes the serialization of the first data and the second data by the serializer 104, and the transmission of the serialized data to the second connection structure 201 through the first connection structure 103, etc.

[0062] If the power-on mode is used to continuously supply power to the powered device, serious voltage fluctuation will occur when the first connection structure 103 and the second connection structure 201 are plugged in, which will cause the electronic components to fail. At the same time, when the first connection structure 103 and the second connection structure 201 are not connected, their respective connection ports are exposed. If the power-on mode is maintained at this time, the exposed ports will easily cause short circuits when they come into contact with conductive media (such as water, etc.), which will seriously damage the related devices.

[0063] Therefore, in this embodiment, the power supply control unit 105 is used to control the power supply, i.e. the power supply is only performed after the connection signal Pog_IN is generated, without using the power-on mode to avoid the defects caused by the power-on mode.

[0064] Embodiment 3:

[0065] The difference between this embodiment and Embodiments 1 or 2 is that the accessory end 100 further includes:

[0066] The accessory type detection unit 106 is connected to the first connection structure 103, and is used to generate a program loading signal matching the accessory type when the first connection structure 103 and the second connection structure 201 are connected, and transmit the program loading signal to the host end 200. The host control unit 203 of the host end 200 loads an application program corresponding to the accessory type according to the program loading signal.

[0067] Specifically, the program loading signal can be an ADC1 signal, which is transmitted to the analog-to-digital conversion unit 204 through the first connection structure 103 and the second connection structure 201. The analog-to-digital conversion unit 204 further converts the program loading signal into a digital loading signal.

[0068] The master control unit 203 receives the digital loading signal, and loads the application program corresponding to the accessory type according to the digital loading.

[0069] Specifically, as shown in Figure 3 The accessory type detection unit 106 includes a first resistor R21 and a second resistor R22, one end of the first resistor R21 is connected to the power supply VIN, the other end is connected in series with the second resistor R22, one end of the second resistor R22 is connected to the digital ground DGND; when the first connection structure 103 and the second connection structure 201 are connected, the resistance voltage of the first resistor R21 and the second resistor R22 changes according to the accessory type, and an ADC1 signal corresponding to the resistance voltage is generated as a program loading signal, the resistance value and the resistance ratio of the first resistor R21 and the second resistor R22 can be determined in advance.

[0070] For example, when the resistance ratio of the first resistor R21 and the second resistor R22 is 3:1, if the first connection structure 103 and the second connection structure 201 are connected, and the ADC1 signal with a voltage of 1 / 4*power supply voltage (i.e. the voltage of the power supply VIN) is generated, it is considered that the accessory only has the first accessory 101 (such as an infrared detector) or only has the second accessory 102 (such as a visible light detector), the analog-to-digital conversion unit 204 further converts the ADC1 signal into a digital loading signal and sends it to the master control unit 203, the master control unit 203 loads the application program matching the first accessory 101 or the second accessory 102 according to the digital loading signal;

[0071] Similarly, if the first connection structure 103 and the second connection structure 201 are connected, and the ADC1 signal with a voltage of 1 / 2*power supply voltage is generated, it is considered that the accessory has both the first accessory 101 and the second accessory 102, the analog-to-digital conversion unit 204 further converts the ADC1 signal into a digital loading signal and sends it to the master control unit 203, the master control unit 203 simultaneously loads the application program matching the first accessory 101 and the second accessory 102 according to the digital loading signal.

[0072] In summary, the application can convert parallel data into serial data through a serializer first, and then transmit the serial data to a deserializer through a connection structure for deserialization, so that the number of signal interfaces is less, and the connection mode of the accessory end and the host end is improved from the traditional coaxial line or twisted pair connection form to the POGO PIN connection mode, the signal transmission between the deserializer and the serializer is realized through mechanical connection, the accessory end can be hot-plugged, the corresponding accessories can be conveniently maintained and replaced, and the application is especially suitable for compact and portable products.

[0073] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
