Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0036] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0037] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0038] Hot-swapping, or hot-plugging, refers to inserting or removing modules, boards, etc., from a system without shutting down the system power, thus not affecting the normal operation of the system. Current endoscopic systems do not have hot-swapping capabilities, making them inconvenient in practical use.
[0039] In view of this, in order to solve the above problems, this application provides an endoscope system control circuit that realizes the hot-swappable function of the endoscope system by setting up an isolation module or other means.
[0040] The control circuit of the endoscope system provided in this application is described below by way of example:
[0041] As one implementation method, please refer to Figure 1 The endoscope system control circuit includes a control module 110, an isolation module 120, an endoscope port 130, a communication module 140, and a light source module 150. The control module 110 is connected to the isolation module 120 and the communication module 140. The isolation module 120 is also connected to the endoscope port 130, and the communication module 140 is also connected to the light source module 150. The endoscope port 130 is used to connect to the endoscope module. The control module 110 is used to communicate with the endoscope module through the isolation module 120 and to supply power to the endoscope module. The control module 110 is also used to communicate with the light source module 150 through the communication module 140.
[0042] It should be noted that the aforementioned endoscope module includes an endoscope insertion section and an operating handle, etc. The endoscope insertion section is connected to the operating handle. The tip of the endoscope insertion section includes an image acquisition module. The endoscope insertion section can enter the stomach through the mouth or other natural orifices. The image acquisition module can acquire images of the body for the doctor to view, and the doctor can hold the operating handle. The aforementioned image acquisition module can be a CMOS sensor or a CCD sensor; this application does not limit the specific sensor used in the image acquisition module.
[0043] By setting up an isolation module, the communication and power supply of the endoscope module can be isolated. Therefore, when the interface is hot-plugged, it will not affect the normal operation of the control module, thus achieving the effect of hot-plugging the port.
[0044] As one implementation method, please refer to Figure 2 The isolation module 120 includes a decoding unit 121, a first signal conversion unit 122, an isolation chip 123, and a second signal conversion unit 124; the endoscope port 130, the decoding unit 121, the first signal conversion unit 122, the isolation chip 123, and the second signal conversion unit 124 are connected in sequence. Furthermore, this application does not limit the model of each unit or chip, as long as they can perform the corresponding functions.
[0045] The endoscope port 130 and the decoding unit 121 are connected via a V-by-one signal interface (a digital interface standard specifically developed for image transmission). The decoding unit 121 decodes the V-by-one signal from the endoscope port 130 and reconstructs the MIPI signal. Specifically, the decoding unit 121 can decode the MIPI signal from the image acquisition module in the endoscope module. Furthermore, the first signal conversion unit 122 converts the MIPI signal into an LVDS signal; simultaneously, the isolation chip 123 isolates the LVDS signal; and the second signal conversion unit 124 converts the isolated LVDS signal back into a MIPI signal and transmits the converted MIPI signal to the control module 110. By combining isolation with signal conversion, data from the endoscope module can be sent to the control module 110. This enables hot-swapping and improves signal transmission speed.
[0046] In one implementation, the endoscope system control circuit further includes a first digital signal isolator 191 and a second digital signal isolator 192, both of which are connected to the endoscope port 130 and the control module 110, respectively. The control module 110 and the endoscope port 130 are connected via the first digital signal isolator 191 for UART signal transmission, and the control module 110 and the endoscope port 130 are also connected via the second digital signal isolator 192 for I2C signal transmission.
[0047] In some examples, the endoscope system control circuit also includes a power isolation chip (not shown in the figure), which is connected to the endoscope port 130 and the control module 110 respectively. The power isolation chip is used to achieve power isolation between the control module 110 and the endoscope port 130.
[0048] Similarly, this application does not limit the specific models of the first digital signal isolator 191, the second digital signal isolator 192, and the power isolation chip, as long as the corresponding signal or power isolation function is implemented.
[0049] After the control module 110 receives the MIPI signal, UART signal, and I2C signal, it can determine whether there is data, whether the MIPI module needs to be reset, and whether the image acquisition module needs to be reinitialized by detecting the MIPI signal and the I2C response signal to achieve hot-swapping.
[0050] Furthermore, in practical applications, the aforementioned multiple isolation chips can be packaged into one unit or set up independently; no limitation is made here.
[0051] As one implementation, the endoscope system control circuit also includes a serial touch screen 160, and the control module 110 can also be used to communicate with the serial touch screen 160 through the communication module 140.
[0052] Specifically, please refer to Figure 3 The communication module 140 includes a first transceiver 141, a control chip 142, and a second transceiver 143. The control chip 142 is connected to the first transceiver 141 and the second transceiver 143 respectively. The first transceiver 141 can be connected to the light source module through an RS232 interface, and the second transceiver 143 is connected to the control module through a UART interface.
[0053] For example, the control chip 142 can control the light source module, such as a narrowband or cold light source module, through the RS232 interface. At the same time, the control chip 142 can also output RS232 through another UART interface and communicate with the control module 110.
[0054] Furthermore, the endoscope system control circuit also includes an air pump, a first fan, a second fan, and a thermistor, and the control chip is connected to the air pump, the first fan, the second fan, and the thermistor respectively.
[0055] The first and second fans can be positioned on either side of the system; for example, the first fan could be located at the top of one side of the system, and the second fan at the top of the other side. Furthermore, a control chip can be used to control the light source module and the air pump, while a thermistor can monitor the temperature and control the first and second fans to achieve heat dissipation.
[0056] As one implementation, the endoscope system control circuit also includes multiple output ports 170 and a storage module 180, all of which are connected to the control module 110. Based on this, the storage module 180 can be used to store relevant data acquired by the endoscope module, and the output ports 170 can be used to connect to external devices and transmit relevant data to those devices.
[0057] As can be seen, the above implementation method enables hot-swapping of the port. Simultaneously, the control module can acquire signals from the endoscope module, adjust the parameters of the light source module 150, and output related signals through the port. Furthermore, by combining isolation with signal conversion, the signal transmission rate can be improved.
[0058] Based on the above implementation, this application embodiment also provides an endoscope system, which includes an endoscope module and the endoscope system control circuit described above, wherein the endoscope port 130 of the endoscope system control circuit is connected to the endoscope module.
[0059] Furthermore, this application embodiment also provides an endoscope image processor, which includes the aforementioned endoscope system control circuit.
[0060] In summary, this application provides an endoscope system control circuit, system, and endoscope image processor. The endoscope system control circuit includes a control module, an isolation module, an endoscope port, a communication module, and a light source module. The control module is connected to the isolation module and the communication module, respectively. The isolation module is also connected to the endoscope port, and the communication module is also connected to the light source module. The endoscope port is used to connect to the endoscope module. The control module communicates with and supplies power to the endoscope module through the isolation module. The control module also communicates with the light source module through the communication module. Because the endoscope system control circuit provided in this application includes an isolation module, which isolates the communication and power supply of the endoscope module, hot-plugging the interface will not affect the normal operation of the control module, achieving a hot-swappable port.

Various modifications and variations can be made to this application by those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
