[0027] Figure 1 The structural diagram of an industrial computer provided by an embodiment of the present application is shown. For the convenience of explanation, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0028] The industrial computer 10 includes: a power module 100, a first control mainboard 200, a second control mainboard 300, an uninterruptible power system technology (UPS) power supply 500, a power failure detection module 400 and a precision connector.

[0029] The power module 100 is used to connect to an external power supply to generate and output a driving voltage based on an input voltage provided by the external power supply, wherein the external power supply can be a power grid or other energy storage device, and the driving voltage can include multiple voltages with different voltage values. The first control mainboard 200 is connected to the power module 100 to access the driving voltage. The first control mainboard 200 can select a driving voltage with a suitable access voltage value according to demand, and the driving voltage can drive the first control mainboard 200 to work. A central processing unit (CPU) is installed on the second control mainboard 300, and the second control mainboard 300 is electrically connected to the first control mainboard 200 through a precision connector. The uninterruptible power supply 500 is electrically connected to the power module 100 and the first control mainboard 200, respectively, and the uninterruptible power supply 500 is used to provide a temporary voltage to the first control mainboard 200. The power-off detection module 400 is electrically connected to the power module 100, the first control mainboard 200 and the second control mainboard 300, and the power-off detection module 400 is used to detect the driving voltage and control the industrial computer 10 to shut down through the second control mainboard 300 when the driving voltage is lower than a preset threshold. The first control mainboard 200 may be used to install other electronic components except the central processing unit. For example, the power-off detection module 400 may be installed on the first control mainboard 200 .

[0030] It should be noted that when the external power supply suddenly stops providing input voltage, the uninterruptible power supply 500 can provide temporary voltage to the first control motherboard 200 to replace the driving voltage to enable the industrial computer 10 to continue working, but the power that the uninterruptible power supply 500 can provide is limited. When the power stored in the uninterruptible power supply 500 is exhausted, the industrial computer 10 will also be powered off.

[0031] When the power failure detection module 400 detects that the driving voltage provided by the power module 100 is less than a preset threshold, it can control the industrial computer 10 to shut down through the second control motherboard 300, and can automatically save relevant data during the period of temporary power supply by the uninterruptible power supply 500 to avoid the impact of power failure on the industrial computer 10.

[0032] The second control mainboard 300 installed with the central processing unit is connected to the first control mainboard 200 through a precision connector. By replacing the second control mainboard 300, the central processing unit and other components installed on the second control mainboard 300 can be quickly replaced, and central processing units of different specifications can be replaced.

[0033] In one embodiment, if Figure 2As shown, the power-off detection module 400 includes a voltage-dividing resistor R1, a bias resistor R2, a current-limiting resistor R3, a voltage-stabilizing diode D1, and an NPN transistor Q1. The first end of the voltage-dividing resistor R1 is connected to the power module 100 to access the driving voltage. For example, the first end of the voltage-dividing resistor R1 can obtain a driving voltage of +28V from the power module 100. The second end of the voltage-dividing resistor R1 is connected to the cathode of the voltage-stabilizing diode D1, the anode of the voltage-stabilizing diode D1 is respectively connected to the first end of the bias resistor R2 and the base of the NPN transistor Q1, the second end of the bias resistor R2 is grounded, the first end of the current-limiting resistor R3 is connected to the first control mainboard 200 to obtain the working voltage provided by the first control mainboard 200, for example, a voltage of 3.3V can be obtained from the first control mainboard 200, the second end of the current-limiting resistor R3 is connected to the second control mainboard 300, the collector of the NPN transistor Q1 is connected to the second end of the current-limiting resistor R3, and the emitter of the NPN transistor Q1 is grounded.

[0034] It should be noted that the preset threshold is determined by the parameters of the voltage regulator diode D1. Exemplarily, when the driving voltage is greater than 20V, the voltage regulator diode D1 is turned on, and the current will pass through the voltage regulator diode D1 to reach the base of the NPN transistor Q1, and the NPN transistor Q1 is turned on, thereby providing a low-level signal to the second control mainboard 300. When the voltage is lower than 20V, the voltage regulator diode D1 is not turned on, and the base of the NPN transistor Q1 is pulled to the ground through the bias resistor R2, and the NPN transistor Q1 is not turned on, thereby providing a high-level signal to the second control mainboard 300. The second control mainboard 300 can judge whether the driving voltage meets the demand through the level provided by the power-off detection module 400. When the driving voltage is lower than the preset threshold, it means that the power module 100 cannot stably provide the driving voltage, and there is a risk of power failure. The second control mainboard 300 can thus control the industrial computer 10 to shut down and reduce losses.

[0035] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes a plurality of DP interfaces 610 , each DP interface 610 is electrically connected to a central processing unit, and the DP interface 610 is used to connect to an external display device.

[0036] The digital video (DisplayPort; DP) interface is mainly used to connect video sources to devices such as monitors, and also supports the transmission of audio, USB and other forms of data.

[0037] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes a plurality of USB interfaces 620 , each of which is electrically connected to the central processing unit, and the USB interfaces 620 are used to connect to external interactive devices.

[0038] The Universal Serial Bus (USB) interface can be connected to various peripherals, such as a mouse and a keyboard, to expand the functions of the industrial computer 10 .

[0039] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes a plurality of RS232 interfaces, each of which is electrically connected to the central processing unit, and the RS232 interfaces are used for serial communication with external devices.

[0040] The RS232 interface is a serial communication interface that can be connected to other industrial equipment to achieve data exchange.

[0041] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes a plurality of RJ45 interfaces 630 , each of which is electrically connected to the central processing unit, and the RJ45 interfaces 630 are used to communicate with external devices through a network.

[0042] The RJ45 interface 630 is a most common network interface, and the relevant network can be connected through the RJ45 interface 630 to achieve communication.

[0043] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes a plurality of PCIE interfaces 640 , each of which is electrically connected to the central processing unit, and the PCIE interface 640 is used to connect to an external expansion device.

[0044] A high-speed serial computer expansion bus standard peripheral component interconnect express (PCIE) interface is widely used in computer devices. More storage devices and the like can be connected through the PCIE interface 640 .

[0045] In one embodiment, if Figure 3 As shown, the industrial computer 10 further includes at least one adapter 700 , the adapter 700 is provided with a PCIE plug and a USB interface 620 , the PCIE plug is docked with the PCIE interface 640 , and the adapter 700 is used for mutual conversion between PCIE signals and USB signals.

[0046] The PCIE interface 640 is converted into a plurality of USB interfaces 620 by the adapter 700, so that the demand for the USB interface 620 can be better met. Whether to install the adapter 700 can be determined according to the actual situation.
