[0044] Compared with personal computers, industrial computers have more stringent application environments and may need to operate in harsh environments such as high temperature, low temperature, vibration, and electrostatic surges. This requires industrial computer motherboards to meet the anti-interference requirements of industrial environments.

[0045] At present, common industrial computer motherboards can meet the needs of some industrial environments. However, due to various factors, industrial computer motherboards often cannot meet the anti-interference requirements of various harsh environments and are not reliable enough. Therefore, there is an urgent need for an industrial computer motherboard with higher reliability.

[0046] Based on this, the present application proposes an industrial motherboard and an industrial computer, which includes: a main control module; a dual BIOS module, the dual BIOS module is connected to the first end of the main control module, and the dual BIOS module is used to switch the BIOS according to the switching signal output by the main control module; a USB self-recovery module, one end of the USB self-recovery module is connected to the second end of the main control module, and the other end of the USB self-recovery module is connected to an external USB device, and the USB self-recovery module is used to reconnect the external USB device according to the recovery signal output by the main control module; an alarm module, one end of the alarm module is connected to the third end of the main control module, and the alarm module is used to alarm according to the alarm signal output by the main control module. The industrial motherboard of the present application realizes the dual BIOS automatic switching function through the main control module and the dual BIOS module, realizes the USB self-recovery function through the main control module and the USB self-recovery module, and realizes the reliability alarm function through the main control module and the alarm module. Compared with the currently commonly used industrial computer motherboard, the industrial motherboard of this embodiment improves the reliability of the industrial motherboard startup, the reliability of the operation of the industrial motherboard external USB device, and provides a reliability alarm function, so that the industrial motherboard can adapt to more complex industrial environments.

[0047] The present application embodiment provides an industrial motherboard, referring to Figure 1 , Figure 1A schematic diagram of the structure of an industrial motherboard provided in one embodiment of the present application, the industrial motherboard includes:

[0048] Main control module 10;

[0049] A dual BIOS module 20, the dual BIOS module 20 is connected to a first end of the main control module 10, and the dual BIOS module 20 is used to perform BIOS switching according to a switching signal output by the main control module 10;

[0050] A USB self-recovery module 30, one end of which is connected to the second end of the main control module 10, and the other end of which is connected to an external USB device, and the USB self-recovery module 30 is used to reconnect the external USB device according to a recovery signal output by the main control module 10;

[0051] An alarm module 40 , one end of which is connected to the third end of the main control module 10 , and the alarm module 40 is used for sounding an alarm according to an alarm signal output by the main control module 10 .

[0052] In the present embodiment, it can be understood that the common basic functions or features of the currently commonly used industrial computer motherboards, for example, anti-static, surge protection, and shockproof in terms of anti-interference; rich I / O ports (input and output ports) in terms of resource expansion, etc., are also possessed by the industrial motherboard of the present embodiment. On this basis, the industrial motherboard of the present embodiment also has a dual BIOS (Basic Input / Output System) automatic switching function, a USB (Universal Serial Bus) self-recovery function, and an alarm function.

[0053] The industrial motherboard includes a main control module 10, a dual BIOS module 20, a USB self-recovery module 30 and an alarm module 40. The main control module 10 is the core of the industrial motherboard. The dual BIOS automatic switching function, the USB self-recovery function and the alarm function all require the control of the main control module 10. The dual BIOS module 20 includes a main BIOS and a secondary BIOS. When the main BIOS is not damaged or abnormal, the motherboard is always started through the main BIOS. Only when the main BIOS is damaged or abnormal, the main control module 10 will output a switching signal to make the secondary BIOS work and complete the startup of the motherboard. The USB self-recovery module 30 is used to achieve the reconnection of the external USB device when an abnormality occurs in the external USB device, so that the external USB device is powered off and restarted, thereby returning to normal. The alarm module 40 can show different alarm states according to different alarm signals output by the main control module 10. For example, when the temperature of the central processing unit is too high, the alarm module 40 shows the alarm state corresponding to the high temperature. When a short circuit occurs, the alarm module 40 shows the alarm state corresponding to the short circuit. This method is convenient for the staff to intuitively observe the fault of the motherboard and quickly take corresponding solutions.

[0054] The industrial motherboard of this embodiment realizes the dual BIOS automatic switching function through the main control module 10 and the dual BIOS module 20, thereby improving the reliability of the industrial motherboard startup, realizes the USB self-recovery function through the main control module 10 and the USB self-recovery module 30, thereby improving the reliability of the operation of the external USB device of the industrial motherboard, and realizes the reliability alarm function through the main control module 10 and the alarm module 40. Compared with the currently commonly used industrial computer motherboards, the industrial motherboard of this embodiment has higher reliability and can adapt to more complex industrial environments.

[0055] Reference Figure 2 In some feasible embodiments, the main control module 10 includes:

[0056] A judgment unit 11, a monitoring unit 12 and a main control unit 13, wherein the judgment unit 11 is connected to the USB self-recovery module 30; the monitoring unit 12 is connected to the central processing unit; the main control unit 13 is respectively connected to the judgment unit 11, the monitoring unit 12, the dual BIOS module 20, the USB self-recovery module 30 and the alarm module 40;

[0057] The judging unit 11 is used to judge the state of the external USB device according to the USB self-recovery module 30, and output a judging signal to the main control unit 13 when the state of the external USB device is abnormal;

[0058] The monitoring unit 12 is used to monitor the state of the central processing unit and output a monitoring signal to the main control unit 13 when the state of the central processing unit is abnormal;

[0059] The main control unit 13 is used to receive the startup feedback signal output by the dual BIOS module 20, and output a switching signal to the dual BIOS module 20 in the event of a startup abnormality. The main control unit 13 is also used to output the recovery signal to the USB self-recovery module 30 according to the judgment signal. The main control unit 13 is also used to output an alarm signal to the alarm module 40 according to the monitoring signal.

[0060] In this embodiment, the judgment unit 11 is connected to the USB self-recovery module 30, and the USB self-recovery module 30 is connected to the external USB device. The device status of the external USB device can be transmitted to the judgment unit 11 through the USB self-recovery module 30. When there is a problem with the device status of the external USB device, such as the external USB device is stuck, the judgment unit 11 queries the status information of the external USB device through the USB self-recovery module 30. When the status information of the external USB device being stuck is queried, the judgment unit 11 outputs a judgment signal to the main control unit 13. The main control unit 13 will output a recovery signal only after receiving the judgment signal, so that the USB self-recovery module 30 performs corresponding actions according to the recovery signal to reconnect the external USB device. The monitoring unit 12 is connected to the central processing unit on the industrial motherboard, that is, the CPU (Central Processing Unit). As an example, the monitoring unit 12 is a different interrupt resource of the main control module 10, and monitors the correctable errors generated in the CPU through the CATERR# signal pin, that is, the error correction error signal pin. When a correctable error is detected, the state of the pin will change. The temperature in the CPU is monitored through the THERMTRIP# signal pin, i.e., the temperature trigger pin. When the temperature detected exceeds the rated temperature of the CPU, the state of the pin will change. Other monitoring of the CPU is set as the above method, and this embodiment will not be repeated. When the monitoring unit 12 detects that the above problem occurs in the CPU, it outputs a monitoring signal to the main control unit 13. The main control unit 13 will output an alarm signal only after receiving the monitoring signal, so that the alarm module 40 alarms according to the alarm signal. The dual BIOS module 20 will output a startup feedback signal to the main control unit 13 during the process of starting the industrial motherboard, which is used for the main control unit 13 to determine whether the industrial motherboard is successfully started according to the startup feedback signal. In the case of abnormal startup, the main control unit 13 outputs a switching signal to the dual BIOS module 20 to switch the main BIOS to the secondary BIOS, thereby successfully starting the industrial motherboard.

[0061] Reference Figure 2 In some feasible embodiments, the main control module 10 further includes:

[0062] The recording unit 14 is connected to the monitoring unit 12 and is used to record the abnormal state of the central processing unit according to the monitoring signal.

[0063] In this embodiment, the recording unit 14 is used to record faults occurring in the CPU, and a memory may be used to store the faults. By recording the faults occurring in the CPU, it is convenient for the staff to query the fault records at any time, thereby strengthening the maintenance and consolidation of the corresponding faults.

[0064] Reference Figure 3 In some feasible embodiments, the dual BIOS module 20 includes:

[0065] A control unit 21, a platform controller 22, a first BIOS unit 23 and a second BIOS unit 24, wherein the control unit 21 is connected to the main control unit 13, the first BIOS unit 23 and the second BIOS unit 24 respectively; and the platform controller 22 is connected to the main control unit 13, the first BIOS unit 23 and the second BIOS unit 24 respectively;

[0066] The control unit 21 is used to transmit the startup feedback signal output by the first BIOS unit 23 or the second BIOS unit 24 to the main control unit 13, and the control unit 21 is also used to disconnect from the first BIOS unit 23 according to the switching signal and connect to the second BIOS unit 24;

[0067] The platform controller 22 is used to read the configuration information of the first BIOS unit 23 and start the mainboard in cooperation with the first BIOS unit 23;

[0068] The platform controller 22 is further configured to read the configuration information of the second BIOS unit 24 according to the switching signal and cooperate with the second BIOS unit 24 to start the mainboard when the first BIOS unit 23 fails to start the mainboard.

[0069] In this embodiment, the platform controller 22 is PCH (Platform Controller Hub), the first BIOS unit 23 is the main BIOS, the second BIOS unit 24 is the secondary BIOS, and the first BIOS unit 23 and the second BIOS unit 24 will output a startup feedback signal during the process of starting the industrial motherboard, and feedback is required to the main control unit 13 regardless of whether the industrial motherboard is successfully started. When starting the industrial motherboard, the PCH needs to be powered on, and the configuration information of the first BIOS unit 23 is read. At the same time, the first BIOS unit 23 initializes the components used for startup on the industrial motherboard and other operations. The industrial motherboard is started with the cooperation of the PCH, the first BIOS unit 23 and other related components used for startup. At the same time, the first BIOS unit 23 outputs a startup feedback signal to inform the main control unit 13 that the industrial motherboard has been successfully started. When the first BIOS unit 23 is damaged, the main control unit 13 learns that the industrial mainboard startup is abnormal based on the startup feedback signal, and the main control unit 13 outputs a switching signal to the control unit 21, and the control unit 21 immediately starts the connection with the second BIOS unit 24. At the same time, the PCH is powered on again and reads the configuration information of the second BIOS unit 24. The second BIOS unit 24 initializes the components used for startup on the industrial mainboard and other operations. The industrial mainboard is started with the cooperation of the PCH and the second BIOS unit 24 and other related components used for startup. At the same time, the second BIOS unit 24 outputs a startup feedback signal to inform the main control unit 13 that the industrial mainboard has been successfully started.

[0070] In some feasible embodiments, the control unit 21 is also used to determine whether the first BIOS unit 23 is connected based on the startup feedback signal when the startup is normal, and disconnect the second BIOS unit 24 and connect to the first BIOS unit 23 when the first BIOS unit 23 is not connected.

[0071] In this embodiment, when the industrial motherboard is successfully started, all components used to start the industrial motherboard do not need to be run again. Therefore, regardless of whether the first BIOS unit 23 is damaged, the first BIOS unit 23 can be reconnected, and the first BIOS unit can be repaired through the maintenance system of the industrial motherboard. At the same time, disconnecting the second BIOS unit 24 can also protect the second BIOS unit 24.

[0072] Reference Figure 3 In some feasible embodiments, the USB self-recovery module 30 includes:

[0073] A status register 31 and a USB interface 32, wherein the status register 31 is connected to the judgment unit 11 and the USB interface 32 respectively, and the USB interface 32 is connected to the main control unit 13 and the external USB device respectively;

[0074] The status register 31 is used to store the status information of the external USB device, so that the determination unit 11 determines whether to output a determination signal according to the status information.

[0075] In this embodiment, the external USB device is connected to the industrial mainboard via the USB interface 32, the status register 32 is connected to the USB interface, and a connection is established with the external USB device via the USB interface 32, thereby storing the status information of the external USB device, and the judgment unit 11 can obtain the status of the external USB device by querying the status information stored in the status register 32, and make a judgment. It can be understood that the industrial mainboard can be provided with multiple USB interfaces 32 for connecting more external USB devices, and a corresponding number of status registers 31 need to be provided at the same time, and the specific structure can be designed and configured according to actual requirements.

[0076] In some feasible embodiments, when the status information of the external USB device stored in the status register 31 is abnormal, the judgment unit 11 outputs a judgment signal to the main control unit 13, the main control unit 13 outputs a recovery signal according to the judgment signal, and the USB interface 32 is powered on again according to the recovery signal to reconnect the USB external device.

[0077] In this embodiment, the status register 31 can store various status information of the external USB device. The judgment unit 11 queries all the status information in the status register 31. When any status information is abnormal, the judgment unit 11 outputs a judgment signal to the main control unit 13, and the main control unit 13 outputs a recovery signal to the USB interface 32, so that the USB interface 32 is powered on again, thereby restarting the external USB device and restoring it to a normal state.

[0078] In some feasible embodiments, the main control module 10 includes an MCU.

[0079] In this embodiment, the main control module 10 may also be other control chips as long as the same technical effect of this embodiment can be achieved.

[0080] In some feasible embodiments, the alarm module 40 includes an alarm light, which flashes or stays on according to the alarm signal to indicate different faults.

[0081] In this embodiment, the alarm light can be an LED light (Light Emitting Diode). The color or on / off of the LED light indicates different states and corresponds to different faults, so that the staff can intuitively understand the specific fault of the industrial motherboard through the LED light and take corresponding measures for maintenance in time.

[0082] The present embodiment provides an industrial motherboard. The industrial motherboard of the present application realizes the automatic switching function of the first BIOS unit and the second BIOS unit by the main control unit and the control unit. When the first BIOS unit is damaged, it switches to the second BIOS unit to complete the startup of the industrial motherboard, thereby improving the reliability of the startup of the industrial motherboard. After the startup is completed, the control unit switches back to the first BIOS unit, and the first BIOS unit is repaired by the maintenance system of the industrial motherboard, which can also protect the second BIOS unit, reduce the power-on time of the second BIOS unit, and improve the service life. The USB self-recovery function is realized by the main control unit, the judgment unit, the status register and the USB interface, thereby improving the reliability of the operation of the external USB device of the industrial motherboard. The alarm module can intuitively display the fault of the CPU of the industrial motherboard, which is convenient for the staff to perform maintenance. At the same time, the recording unit is used to record the fault of the CPU, which is convenient for the staff to query the fault record at any time, thereby strengthening the maintenance and consolidation of the corresponding fault. The industrial motherboard of this embodiment has higher reliability than the currently commonly used industrial computer motherboard, so that the industrial motherboard can adapt to more complex industrial environments.
