[0062] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0063] Moreover, in the description of the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0064] The application scenarios of a cold light source device provided by an embodiment of the present application are introduced below with reference to the accompanying drawings. The medical cold light source device is used in endoscope diagnosis and surgery to provide illumination for the field of view area where the endoscope observes the human body cavity. As Figure 1 shown, an endoscope generally includes a cold light source device, an imaging device and a display device. The imaging device can be used to take pictures of endoscope examinations and surgeries to collect picture data of the examinations and surgeries. Its key components may include one or more of a camera, a power on / off button, an imaging host, a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor, a video cable, an optical adapter, an objective lens field of view, a rod, a communication port and a video output interface. The imaging host can be connected to the display device through the video output interface and connected to the cold light source host through the communication port.

[0065] In the embodiments of the present application, the objective lens field of view, the rod, the optical adapter, the button, the CMOS and the camera in the key components of the imaging device can also be collectively referred to as an endoscope camera.

[0066] The display device can be a monitor, which is used to display the endoscopic images collected and generated by the imaging device.

[0067] The cold light source device can be used to provide illumination light for the endoscope during endoscopic examinations and surgeries; its key components usually include: a cold light source host, a power on / off button, a light guide beam, a communication port, and a cold light source light output interface.

[0068] However, in the related art, the power on and off of the cold light source device, and the power on and off of the imaging device are controlled separately. When powering on or off, the switch button needs to be long-pressed, resulting in an increase in the operation time for powering on or off and cumbersome operation.

[0069] Based on the above problems, an embodiment of the present application provides a cold light source device, as Figure 2 shown, is a schematic diagram of a cold light source device provided by the present utility model. The device includes: a first switching power supply module 301, a first control module 302, and a first communication port 303;

[0070] The first communication port 303 is electrically connected to the imaging device 304 and the first control module 302 respectively, and is used for, after receiving a first level signal representing power on sent by the imaging device 304, obtaining a third level signal representing that the cold light source device is in a power-off state from the first control module 302; converting the first level signal into a second level signal representing power on, and sending the second level signal to the first control module 302;

[0071] The first control module 302 is electrically connected to the first switching power supply module 301, and is used for, after receiving the second level signal, sending a first instruction signal representing power on to the first switching power supply module 301;

[0072] The first switching power supply module 301 is used to control the cold light source device to power on based on the received first instruction signal representing power on.

[0073] The cold light source device provided by the embodiment of the present utility model includes: a first switching power supply module, a first control module, and a first communication port. The first communication port is electrically connected to the imaging device and the first control module respectively, and is configured to obtain a third level signal indicating that the cold light source device is in a shutdown state from the first control module after receiving a first level signal indicating startup sent by the imaging device; convert the first level signal into a second level signal indicating startup, and send the second level signal to the first control module; the first control module is electrically connected to the first switching power supply module, and is configured to send a first instruction signal indicating startup to the first switching power supply module after receiving the second level signal; the first switching power supply module is configured to control the cold light source device to start up based on the received first instruction signal indicating startup. That is to say, the first communication port can convert the first level signal indicating startup sent by the imaging device into a second level signal indicating startup and control the cold light source device to start up, so as to realize that when the imaging device starts up, the cold light source device follows the imaging device to start up without separate control, and the operation is convenient.

[0074] It should be noted that after the cold light source device is powered on, it is in a standby state, that is, the first control module 302 and the first communication port 303 can work.

[0075] In the embodiment of the present utility model, when the imaging device 304 is in a shutdown state, the user presses the power-on / off button of the imaging device 304, and the imaging device 304 responds to the startup operation triggered by the user. The imaging device 304 sends a first level signal indicating startup to the first communication interface 303 in the cold light source device. After the first communication port 303 receives the first level signal indicating startup, it obtains the level signal indicating the current startup / shutdown state of the cold light source device from the first control module 302. If it obtains a third level signal indicating that the cold light source device is in a shutdown state, it converts the first level signal into a second level signal indicating startup. If the first communication port 303 obtains a level signal indicating that the cold light source device is in a startup state, the cold light source device does not perform any action.

[0076] In a specific implementation, the first level signal indicating startup may be a high level signal, the third level signal indicating that the cold light source device is in a shutdown state may be a low level signal, and the second level signal indicating startup may be a high level signal.

[0077] Such as Figure 3As shown in the figure, it is a schematic structural diagram of another cold light source device provided by an embodiment of the present application. The first communication port 303 includes a first transceiver 401. The first transceiver 401 includes a first level receiving end RX1, a second level receiving end RX2, a first level sending end TX1, and a second level sending end TX2. The first level receiving end RX1 and the second level sending end TX2 are electrically connected to the imaging device 304. The second level receiving end RX2 and the first level sending end TX1 are respectively electrically connected to the first control module 302.

[0078] Specifically, the first transceiver 401 is electrically connected to the imaging device 304 through the first level receiving end RX1, and is used to receive the first level signal representing power-on sent by the imaging device 304. It is electrically connected to the first control module 302 through the second level receiving end RX2, and is used to receive the third level signal representing that the cold light source device is in the shutdown state sent by the first control module 302. It is electrically connected to the first control module 302 through the first level sending end TX1, and is used to convert the first level signal into a second level signal and then send the second level signal to the first control module 302 to control the power-on of the cold light source device. It is electrically connected to the imaging device 304 through the second level sending end TX2, and is used to send the third level signal to the imaging device 304.

[0079] It should be noted that if the imaging device 304 receives the third level signal representing that the cold light source device is in the shutdown state, it determines that the cold light source device is in the shutdown state.

[0080] In another embodiment, as Figure 4 shown in the figure, it is a schematic structural diagram of another cold light source device provided by an embodiment of the present application. The first communication port 303 further includes a first interface board 601. The first interface board 601 includes level receiving terminals. The first end R1 of the level receiving terminal is electrically connected to the imaging device 304, and the second end R2 of the level receiving terminal is electrically connected to the first level receiving end RX1 of the first transceiver 401. In addition, the first interface board 601 further includes level sending terminals. The first end T1 of the level sending terminal is electrically connected to the imaging device 304, and the second end T2 of the level sending terminal is electrically connected to the second level sending end TX2 of the first transceiver 401.

[0081] Specifically, the first interface board 601 is electrically connected to the imaging device 304 through the first end R1 of the level receiving terminal, and is used to receive the first level signal indicating startup sent by the imaging device 304; it is electrically connected to the first level receiving end RX1 of the first transceiver 401 through the second end R2 of the receiving terminal, and is used to send the first level signal indicating startup received by the first interface board 601 to the first transceiver 401; it is electrically connected to the second level sending end TX2 of the first transceiver 401 through the second end T2 of the level sending terminal, and is used to receive the third level signal sent by the first transceiver 401 indicating that the cold light source device is in the shutdown state; it is electrically connected to the imaging device 304 through the first end T1 of the level sending terminal, and is used to send the received third level signal to the imaging device 304.

[0082] It should be noted that the first end R1 of the level receiving terminal of the first interface board can be electrically connected to the sending end of the controller in the imaging device 304, and the first end T1 of the level sending terminal of the first interface board can be electrically connected to the receiving end of the controller in the imaging device 304. That is to say, when the imaging device receives the startup instruction and starts up, the sending end of the controller in the imaging device sends the first level signal indicating startup to the communication port of the cold light source device.

[0083] After the first control module 302 obtains the third level signal indicating that the cold light source device is in the shutdown state, it sends the third level signal to the first transceiver 401. After the first transceiver 401 receives the third level signal, it sends the third level signal to the first interface board. The first interface board then sends the third level signal to the receiving end of the controller in the imaging device. After the receiving end of the controller in the imaging device receives the third level signal, it determines whether the cold light source device is in the startup state according to the third level signal.

[0084] It should be noted that as Figure 5 shown, the first transceiver 401 can be a level conversion chip. The level conversion chip includes a first level receiving end RX1, a second level receiving end RX2, a first level sending end TX1, and a second level sending end TX2. Among them, the level conversion chip can be a MAX3232 chip, which is used to convert the first level signal indicating startup sent by the imaging device 304 into a second level signal and send the second level signal to the first control module 302, so that the first control module 302 sends an instruction signal indicating startup to the switching power supply module 301 based on the second level signal to control the startup of the cold light source device, and is used to send the third level signal indicating that the cold light source device is in the shutdown state obtained from the first control module 302 to the imaging device 304.

[0085] When the level conversion chip is a MAX3232 chip, the first level receiving end RX1 can be the 14th pin PCRXD15 of the MAX3232 chip, the first level transmitting end TX1 can be the 11th pin UART_TXD12 of the MAX3232 chip, the second level receiving end RX2 can be the 12th pin UART_RXD12 of the MAX3232 chip, and the second level transmitting end TX2 can be the 13th pin PCTXD15 of the MAX3232 chip; the first level receiving end RX1 can also be the 7th pin 5PCRXD3 of the MAX3232 chip, the first level transmitting end TX1 can also be the 10th pin UART_TXD32 of the MAX3232 chip, the second level receiving end RX2 can also be the 9th pin UART_RXD32 of the MAX3232 chip, and the second level transmitting end TX2 can also be the 8th pin 5PCTXD3 of the MAX3232 chip.

[0086] The level conversion chip can convert the UART level to the RS232 level or convert the RS232 level to the UART level.

[0087] In one embodiment, as Figure 6 shown, it is a schematic structural diagram of another cold light source device provided by an embodiment of the present application. The first switching power supply module 301 includes a main path output end and an auxiliary path output end. The device further includes a first power isolation module 801; the main path output end is electrically connected to the first input end of the first power isolation module 801; the auxiliary path output end is electrically connected to the second input end of the first power isolation module 801; the output end of the first power isolation module 801 is electrically connected to the first control module 302; the first power isolation module 801 is used to isolate the voltage output by the main path output end from the voltage output by the auxiliary path output end, and provide a power supply voltage for the first control module 302; wherein, the voltage output by the main path output end is greater than the voltage output by the auxiliary path output end.

[0088] Specifically, when the cold light source device is connected to the AC power supply 220V input, the auxiliary path output end generates an output voltage to provide a power supply voltage for the first control module 302, and the cold light source device is in a standby state. When the first control module 302 sends an instruction signal indicating startup to the second switching power supply module 301 based on the second level signal, the first switching power supply module 301 bypasses the auxiliary path output, and the first switching power supply module 301 turns on the main path output, that is, the main path output end provides a power supply voltage for the first control module 302, that is, only the output end of one path provides a power supply voltage for the first control module 302 at the same time. It should be noted that the voltage output by the auxiliary path output end is less than the voltage output by the main path output end, which can reduce the standby power consumption.

[0089] Among them, the voltage output by the main road output terminal can be 12V, and the voltage output by the auxiliary road output terminal can be 5V.

[0090] As Figure 7 shown, it is a schematic structural diagram of another cold light source device provided by an embodiment of the present application. The first power isolation module includes a first diode D1 and a second diode D2; the anode of the first diode D1 is electrically connected to the main road output terminal, and the cathode of the first diode D1 is electrically connected to the cathode of the second diode D2 and the first control module 302; the anode of the second diode D2 is electrically connected to the auxiliary road output terminal.

[0091] Specifically, the first diode D1 is used to isolate the voltage output by the auxiliary road, and the second diode D2 is used to isolate the voltage output by the main road.

[0092] In another embodiment, as Figure 8 shown, it is a schematic structural diagram of another cold light source device provided by an embodiment of the present application. The first control module 302 includes a first DC converter 901 and a first controller 902; the input terminal of the first DC converter 901 is electrically connected to the cathodes of the first diode D1 and the second diode D2, and the output terminal of the first DC converter 901 is electrically connected to the power supply terminal of the first controller 902.

[0093] Specifically, the first DC converter 901 is used to convert the voltage output by the main road output terminal or the voltage output by the auxiliary road output terminal received into the power supply voltage required by the first controller 902. That is, when the cold light source device is connected to the 220V AC power supply input, the auxiliary road output terminal generates an output voltage, and the first DC converter 901 converts the voltage output by the auxiliary road output terminal into the power supply voltage required by the first controller 902 to provide the power supply voltage for the first control module 302; when the first control module 302 sends an instruction signal indicating startup to the first switching power supply module 301 based on the second level signal, the first switching power supply module 301 bypasses the auxiliary road output, and the main road output terminal generates an output voltage. The first DC converter 901 converts the voltage output by the main road output terminal into the power supply voltage required by the first controller to provide the power supply voltage for the first control module 302. Among them, the power supply voltage required by the first controller can be 3.3V.

[0094] It should be noted that the first diode D1, the second diode D2, the first DC converter 901 and the first controller 902 can be arranged on the main control board 903.

[0095] In addition, the first communication port can also be electrically connected to other main control devices and control modules respectively, so as to realize that the cold light source device starts up following the startup of other main control devices.

[0096] In the cold light source device provided by the embodiment of the present utility model, the first communication port 303 can also obtain a sixth level signal indicating that the cold light source device is in the on state from the first control module 302 after receiving a fourth level signal indicating shutdown sent by the imaging device 304; convert the fourth level signal into a fifth level signal indicating shutdown, and send the fifth level signal to the first control module 302;

[0097] After receiving the fifth level signal, the first control module 302 sends a second command signal indicating shutdown to the first switching power supply module 301;

[0098] Based on the received second command signal indicating shutdown, the first switching power supply module 301 controls the cold light source device to shut down.

[0099] The cold light source device provided by the embodiment of the present utility model can achieve that the cold light source device shuts down following the shutdown of the imaging device, with convenient operation.

[0100] In one embodiment, the first communication port 303 includes a first transceiver 401. The first transceiver 401 is electrically connected to the imaging device 304 through a first level receiving end RX1, and is used for receiving a fourth level signal indicating the shutdown state sent by the imaging device 304. It is electrically connected to the first control module 302 through a second level receiving end RX2, and is used for receiving a sixth level signal indicating that the cold light source device is in the on state sent by the first control module 302. It is electrically connected to the first control module 302 through a first level sending end TX1, and is used for converting the fourth level signal into a fifth level signal and sending the fifth level signal to the first control module 302 to control the shutdown of the cold light source device. It is electrically connected to the imaging device 304 through a second level sending end TX2, and is used for sending the sixth level signal to the imaging device 304.

[0101] It should be noted that after receiving the sixth level signal, the imaging device 304 determines that the cold light source device is in the on state.

[0102] In one embodiment, the first communication port 303 further includes a first interface board 601, and the first interface board 601 includes a level receiving terminal; specifically, the first interface board 601 is electrically connected to the imaging device 304 through the first end R1 of the level receiving terminal, and is configured to receive a fourth level signal indicating shutdown sent by the imaging device 304; it is electrically connected to the first level receiving end RX1 of the first transceiver 401 through the second end R2 of the receiving terminal, and is configured to send the fourth level signal indicating shutdown received by the first interface board 601 to the first transceiver 401; it is electrically connected to the fourth level sending end TX4 of the first transceiver 401 through the second end T2 of the level sending terminal, and is configured to receive a sixth level signal sent by the first transceiver 401 indicating that the cold light source device is in a shutdown state; it is electrically connected to the imaging device 304 through the first end T1 of the level sending terminal, and is configured to send the received sixth level signal to the imaging device 304.

That is to say, when the imaging device receives a shutdown instruction, the sending end of the controller in the imaging device sends a fourth level signal indicating shutdown to the communication interface in the cold light source device.

[0104] After the first control module 301 obtains the sixth level signal indicating that the cold light source device is in an on state, it sends the sixth level signal to the first transceiver. After the first transceiver receives the sixth level signal, the first transceiver sends the sixth level signal to the first interface board, and the first interface board sends the sixth level signal to the receiving end of the controller in the imaging device. After the receiving end of the controller in the imaging device receives the sixth level signal, it determines that the cold light source device is in an on state according to the sixth level signal.

Among them, the level conversion chip can be a MAX3232 chip, which is configured to convert the fourth level signal indicating shutdown sent by the imaging device 304 into a fifth level signal and send the fifth level signal to the first control module 302, so that the first control module 302 sends an instruction signal indicating shutdown to the first switching power supply module 301 based on the fifth level signal to control the cold light source device to shut down, and is configured to send the sixth level signal indicating that the cold light source device is in an on state obtained from the first control module 302 to the imaging device 304.

[0118] It should be noted that the cold light source host in the cold light source device includes a first switching power supply module 301, a first power isolation module 801, a first control module 302, a first transceiver 401, a first interface board 601 and a switch button.

[0119] Based on the same inventive concept, the embodiment of the present invention also provides a camera device, and the principle of this camera device is similar to that of the above cold light source device, and the repeated parts will not be described again.

[0120] As shown Figure 9 in the figure, it is a schematic structural diagram of a camera device provided by an embodiment of the present invention. The camera device includes: a second switching power supply module 1001, a second control module 1002, and a second communication port 1003;

[0121] The second communication port 1003 is electrically connected to the cold light source device 1004 and the second control module 1002 respectively, and is used for obtaining a ninth level signal indicating that the camera device is in a shutdown state from the second control module 1002 after receiving a seventh level signal indicating startup sent by the cold light source device 1004; converting the seventh level signal into an eighth level signal indicating startup, and sending the eighth level signal to the second control module 1002;

[0124] The camera device provided by the embodiment of the present invention includes: a second switching power supply module 1001, a second control module 1002, and a second communication port 1003. The second communication port 1003 is electrically connected to the cold light source device 1004 and the second control module 1002 respectively, and is used for obtaining a ninth level signal indicating that the camera device is in a shutdown state from the second control module 1002 after receiving a seventh level signal indicating startup sent by the cold light source device 1004; converting the seventh level signal into an eighth level signal indicating startup, and sending the eighth level signal to the second control module 1002; the second control module 1002 is electrically connected to the second switching power supply module 1001, and is used for sending a third instruction signal indicating startup to the second switching power supply module 1001 after receiving the eighth level signal; the second switching power supply module 1001 is used for controlling the camera device to start up based on the received third instruction signal indicating startup. That is to say, the second communication port 1003 can convert the seventh level signal indicating startup sent by the cold light source device into an eighth level signal indicating startup and control the startup of the camera device, so that when the cold light source device starts up, the camera device starts up with the cold light source device without separate control, and the operation is convenient.

[0125] It should be noted that after the camera device is powered on, it is in a standby state, that is, the second control module 1002 and the second communication port 1003 can work.

[0126] In the embodiment of the present utility model, when the cold light source device 1004 is in the shutdown state, the user presses the power-on / off button of the cold light source device 1004, and the cold light source device 1004 responds to the power-on operation triggered by the user. The cold light source device 1004 sends a seventh-level signal indicating power-on to the second communication port 1003 of the imaging device. When the second communication port 1003 receives the seventh-level signal indicating power-on, it obtains the level signal indicating the current power-on / off state of the imaging device from the second control module 1002. If the ninth-level signal indicating that the imaging device is in the shutdown state is obtained, the seventh-level signal is converted into an eighth-level signal indicating power-on. If the second communication port 1003 obtains the level signal indicating that the imaging device is in the power-on state, the imaging device does not perform any action.

[0127] In a specific implementation, the seventh-level signal indicating power-on can be a high-level signal, the ninth-level signal indicating that the imaging device is in the shutdown state can be a low-level signal, and the eighth-level signal indicating power-on can be a high-level signal.

[0128] As Figure 10 shown, it is a schematic structural diagram of another imaging device provided by the embodiment of the present application. The second communication port 1003 includes a second transceiver 1005. The second transceiver 1005 includes a third-level receiving end RX3, a fourth-level receiving end RX4, a third-level sending end TX3, and a fourth-level sending end TX4. The third-level receiving end RX3 and the fourth-level sending end TX4 are electrically connected to the cold light source device 1004. The fourth-level receiving end RX4 and the third-level sending end TX3 are respectively electrically connected to the second control module 1002.

[0129] Specifically, the second transceiver 1005 is electrically connected to the cold light source device 1004 through the third-level receiving end RX3, and is used to receive the seventh-level signal indicating power-on sent by the cold light source device 1004. It is electrically connected to the second control module 1002 through the fourth-level receiving end RX4, and is used to receive the ninth-level signal indicating that the imaging device is in the shutdown state sent by the second control module 1002.

It is electrically connected to the cold light source device 1004 through the fourth-level sending end TX4, and is used to send the ninth-level signal to the cold light source device 1004.

[0130] It should be noted that if the cold light source device 1004 receives the ninth-level signal indicating that the imaging device is in the shutdown state, it determines that the imaging device is in the shutdown state.

[0131] In another embodiment, as Figure 11As shown in the figure, it is a schematic structural diagram of another imaging device provided by an embodiment of the present application. The second communication port 1003 further includes a second interface board 1101, and the second interface board 1101 includes a level receiving terminal; the third terminal R3 of the level receiving terminal is electrically connected to the cold light source device 1004, and the fourth terminal R4 of the level receiving terminal is electrically connected to the third level receiving end RX3 of the second transceiver 401. In addition, the second interface board 1101 further includes a level sending terminal, the third terminal T3 of the level sending terminal is electrically connected to the cold light source device 304, and the fourth terminal T4 of the level sending terminal is electrically connected to the fourth level sending end TX4 of the second transceiver 401.

[0132] Specifically, the second interface board 1101 is electrically connected to the cold light source device 1004 through the third terminal R3 of the level receiving terminal, and is used to receive the seventh level signal indicating power-on sent by the cold light source device 1004; it is electrically connected to the third level receiving end RX3 of the second transceiver 1005 through the fourth terminal R4 of the receiving terminal, and is used to send the seventh level signal indicating power-on received by the second interface board 1101 to the second transceiver 1005; it is electrically connected to the fourth level sending end TX4 of the second transceiver 1005 through the fourth terminal T4 of the level sending terminal, and is used to receive the ninth level signal sent by the second transceiver 1005 indicating that the imaging device is in the shutdown state; it is electrically connected to the cold light source device 1004 through the third terminal T3 of the level sending terminal, and is used to send the received ninth level signal to the cold light source device 1004.

[0133] It should be noted that the third terminal R3 of the level receiving terminal of the second interface board can be electrically connected to the sending end of the controller in the cold light source device 1004, and the third terminal T3 of the level sending terminal of the second interface board can be electrically connected to the receiving end of the controller in the cold light source 1004. That is to say, when the cold light source device receives the power-on instruction and powers on, the sending end of the controller in the cold light source device sends the seventh level signal indicating power-on to the communication port of the imaging device.

[0134] After the second control module 1002 obtains the ninth level signal indicating that the imaging device is in the shutdown state, it sends the ninth level signal to the second transceiver 1005. After the second transceiver 1005 receives the ninth level signal, it sends the ninth level signal to the second interface board 1101. The second interface board 1101 then sends the ninth level signal to the receiving end of the controller in the cold light source device. After the receiving end of the controller in the cold light source device receives the ninth level signal, it determines that the imaging device is in the shutdown state according to the ninth level signal.

[0135] It should be noted that the second transceiver 1005 can be a level conversion chip, which includes a third level receiving end RX3, a fourth level receiving end RX4, a third level sending end TX3, and a fourth level sending end TX4. Among them, the level conversion chip can be a MAX3232 chip, which is used to convert the seventh level signal indicating startup received from the cold light source device 1004 into an eighth level signal and send the eighth level signal to the second control module 1002, so that the second control module 1002 sends an instruction signal indicating startup to the second switching power supply module 1001 based on the eighth level signal to control the startup of the imaging device, and is also used to send the ninth level signal indicating that the imaging device is in the shutdown state obtained from the second control module 1002 to the cold light source device 1004.

[0136] The level conversion chip can convert UART level to RS232 level, or convert RS232 level to UART level.

[0137] In one embodiment, as Figure 12 shown, the second switching power supply module 1001 includes a main output end and a secondary output end, and the imaging device further includes a second power isolation module 1201; the main output end is electrically connected to the first input end of the second power isolation module 1201; the secondary output end is electrically connected to the second input end of the second power isolation module 1201; the output end of the second power isolation module 1201 is electrically connected to the second control module 1002; the second power isolation module 1201 is used to isolate the voltage output by the main output end from the voltage output by the secondary output end and provide a power supply voltage for the second control module 1002; among them, the voltage output by the main output end is greater than the voltage output by the secondary output end.

[0138] Specifically, when the imaging device is connected to the 220V AC power input, the secondary output end generates an output voltage to provide a power supply voltage for the second control module 1002, and the imaging device is in the standby state. When the second control module 1002 sends an instruction signal indicating startup to the second switching power supply module 1001 based on the eighth level signal, the second switching power supply module 1001 bypasses the secondary output, and the second switching power supply module 1001 turns on the main output, that is, the main output end provides a power supply voltage for the second control module 1002, that is, only the output end of one path provides a power supply voltage for the second control module 1002 at the same time. It should be noted that the voltage output by the secondary output end is less than the voltage output by the main output end, which can reduce the standby power consumption.

[0139] Among them, the voltage output by the main output end can be 12V, and the voltage output by the secondary output end can be 5V.

[0140] In one embodiment, as Figure 13As shown in the figure, the second power isolation module 1201 includes a third diode D3 and a fourth diode D4; the anode of the third diode D3 is electrically connected to the main path output terminal, and the cathode of the third diode D3 is electrically connected to the cathode of the fourth diode D4 and the second control module 1002; the anode of the fourth diode D4 is electrically connected to the auxiliary path output terminal.

[0144] Specifically, the second DC converter 1401 is used to convert the voltage output from the main path output terminal or the voltage output from the auxiliary path output terminal received into the power supply voltage required by the second controller 1402, that is, when the imaging device is connected to the AC power supply 220V input, the auxiliary path output terminal generates an output voltage, and the second DC converter 1401 converts the voltage output from the auxiliary path output terminal into the power supply voltage required by the second controller 1402 to provide the power supply voltage for the second control module 1402; when the second control module 1002 sends an instruction signal indicating startup to the second switching power supply module 1001 based on the eighth level signal, the second switching power supply module 1001 bypasses the auxiliary path output, and the main path output terminal generates an output voltage, and the second DC converter 1401 converts the voltage output from the main path output terminal into the power supply voltage required by the second controller 1402 to provide the power supply voltage for the second control module 1002. Among them, the power supply voltage required by the second controller can be 3.3V.

[0145] In addition, the second communication port 1003 can also be electrically connected to other main control devices and control modules respectively, so as to realize that the imaging device starts up following the startup of other main control devices.

[0146] In an imaging device provided by an embodiment of the present invention, the second communication port 1003 can also obtain a twelfth level signal indicating that the imaging device is in the startup state from the second control module 1002 after receiving a tenth level signal indicating shutdown sent by the cold light source device 1004; convert the tenth level signal into an eleventh level signal indicating shutdown, and send the eleventh level signal to the second control module 1002;

[0147] After receiving the eleventh level signal, the second control module 1002 sends a fourth instruction signal indicating shutdown to the second switching power supply module 1001;

[0148] Based on the received fourth instruction signal indicating shutdown, the second switching power supply module 100 controls the camera device to shut down.

[0149] The camera device provided by the embodiment of the present utility model can realize that the camera shuts down following the shutdown of the cold light source device, and the operation is convenient.

[0150] In one embodiment, the second communication port 1003 includes a second transceiver 1005. The second transceiver 1005 is electrically connected to the cold light source device 1004 through a third level receiving end RX3, and is used to receive the tenth level signal indicating shutdown sent by the cold light source device 1004. It is electrically connected to the second control module 1002 through a fourth level receiving end RX4, and is used to receive the twelfth level signal indicating that the camera device is in the power-on state sent by the second control module 1002. It is electrically connected to the second control module 1002 through a second level sending end TX2, and is used to convert the tenth level signal into an eleventh level signal and then send the eleventh level signal to the second control module 1002 to control the shutdown of the camera device. It is electrically connected to the cold light source device 1004 through a fourth level sending end TX4, and is used to send the twelfth level signal to the cold light source device 1004.

[0151] It should be noted that after the camera device 304 receives the twelfth level signal, it determines that the cold light source device is in the power-on state.

[0152] In one embodiment, the second communication port 1003 further includes a second interface board 1101. Specifically, the second interface board 1101 is electrically connected to the cold light source device 1004 through a third end R3 of a level receiving terminal, and is used to receive the tenth level signal indicating shutdown sent by the cold light source device 1004; it is electrically connected to the third level receiving end RX3 of the second transceiver 1005 through a fourth end R4 of a receiving terminal, and is used to send the tenth level signal indicating shutdown received by the second interface board 1101 to the second transceiver 1005; it is electrically connected to the fourth level sending end TX4 of the second transceiver 1005 through a fourth end T4 of a level sending terminal, and is used to receive the twelfth level signal indicating that the camera device is in the power-on state sent by the second transceiver 1005; it is electrically connected to the cold light source device 1004 through a third end T3 of a level sending terminal, and is used to send the received twelfth level signal to the cold light source device 1004.

That is to say, when the cold light source device receives a shutdown instruction, the sending end of the controller in the cold light source device sends a tenth level signal indicating shutdown to the communication port of the imaging device.

[0154] After the second control module 1002 obtains the twelfth level signal indicating that the imaging device is in the boot state, it sends the twelfth level signal to the second transceiver 1005. After the second transceiver 1005 receives the twelfth level signal, it sends the twelfth level signal to the second interface board 1101. The second interface board 1101 then sends the twelfth level signal to the receiving end of the controller in the cold light source device. After the receiving end of the controller in the cold light source device receives the twelfth level signal, it determines that the imaging device is in the boot state according to the twelfth level signal.

[0155] It should be noted that the second transceiver 1005 can be a level conversion chip. The level conversion chip includes a third level receiving end RX3, a fourth level receiving end RX4, a third level sending end TX3, and a fourth level sending end TX4. Among them, the level conversion chip can be a MAX3232 chip, which is used to convert the tenth level signal indicating shutdown sent by the cold light source device 1004 into an eleventh level signal and send the eleventh level signal to the second control module 1002, so that the second control module 1002 sends an instruction signal indicating shutdown to the second switching power supply module 1001 based on the eleventh level signal to control the imaging device to shut down, and is used to send the twelfth level signal indicating that the imaging device is in the boot state obtained from the second control module 1002 to the cold light source device 1004.
