[0026] Referring Figure 1 , an embodiment of the present utility model provides a hardware redundant watchdog device for monitoring an industrial server 4. As Figure 1 shown, the device includes a single-chip microcomputer 1, and a chip connection module 2 and an alarm module 3 respectively connected to the single-chip microcomputer 1;

[0027] The single-chip microcomputer 1 includes a central processing unit 11. The chip connection module 2 includes a physical layer chip 21, a network isolation chip 23, an RS485 interface chip 24, and a network interface chip 22. Among them, one end of the central processing unit 11 is connected to the alarm module 3, and the other end of the central processing unit 11 is connected to the industrial server 4 through the RS485 interface chip 24 or the network interface chip 22. The physical layer chip 21 is respectively connected to the central processing unit 11 and the network interface chip 22. The network isolation chip 23 is respectively connected to the central processing unit 11 and the RS485 interface chip 24.

[0028] From Figure 1 it can be seen that there are two connection channels with the industrial server 4 in the hardware redundant watchdog device in the present application, namely single-chip microcomputer 1 - physical layer chip 21 - network interface chip 22 - industrial server 4, and single-chip microcomputer 1 - network isolation chip 23 - RS485 interface chip 24 - industrial server 4. After the single-chip microcomputer 1 in the hardware redundant watchdog device establishes a connection with the industrial server 4 by any method, the running information in the industrial server 4 is transmitted to the central processing unit 11 through this connection channel for analysis, and the analysis result is sent to the alarm module 3 to make it alarm to indicate that there is an abnormality in the running state of the industrial server 4 and remind the operation and maintenance personnel. By expanding the hardware redundant watchdog device on the basis of the traditional industrial server 4, the present application monitors and analyzes the running state of the industrial server 4 in real time, and will alarm and remind and warn the operation and maintenance personnel when an abnormal running state is detected, so as to reduce the losses caused by the industrial server 4 due to the difficult discovery of abnormalities.

[0029] Among them, the single-chip microcomputer 1, which can also be regarded as a Microcontroller Unit (MCU), can be a 51 series single-chip microcomputer, an AVR series single-chip microcomputer, an ARM series single-chip microcomputer, a PIC series single-chip microcomputer, an ESP series single-chip microcomputer, etc. It is mainly used to analyze the status data of the industrial server 4 and generate a control signal according to the analysis result and send it to the alarm module 3. Specifically, when it is detected that the signal representing the operating status data of the industrial server 4 does not change within a period of time, an analysis result of the abnormal operation of the industrial server 4 is obtained, and a control signal is generated and sent to the alarm module 3 to trigger the alarm module 3 to alarm. Since the data of the industrial server 4 changes in real time during normal operation, and the signal representing the operating status data also changes in real time, when the signal does not change within the preset time period, it can be determined that the operating status of the industrial server 4 is abnormal.

[0030] The chip connection module 2 in this application is integrated by a physical layer chip 21, a network isolation chip 23, an RS485 interface chip 24, and a network interface chip 22. The chips in this module are divided into two paths. One path is the physical layer chip 21 and the network interface chip 22, and the other path is the network isolation chip 23 and the RS485 interface chip 24. Two channels are set in the chip connection module 2 so that it can be used as a redundant backup for each other. When one of the channels fails, the other channel can continue to work to ensure the continuity and stability of data transmission. Through two independent connection channels, it is also easier to achieve fault isolation. When it is detected that a problem occurs in a certain channel, the channel can be quickly closed to prevent the failure from spreading to the entire device and ensure the security of data transmission.

[0031] In one embodiment, the network interface chip 22 is connected to the industrial server 4 via Ethernet, and the RS485 interface chip 24 is connected to the industrial server 4 via hardwiring or serial port. The two connection channels can be configured according to different communication methods. Among them, the network interface chip 22, also known as an Ethernet interface chip or network interface controller (NIC), is mainly used to establish a connection with the industrial server 4 via Ethernet, transmit and receive signal data indicating the operating state in the industrial server 4 through the physical layer chip 21, and send it to the central processing unit 11. The network interface chip 22 can adopt RTL8153, CH9121 / CH9120, CYUSB3610, etc. The physical layer chip 21 (PHY chip) is used to transmit the analog signal indicating the operating state of the industrial server 4 received from the network interface chip 22 to the central processing unit 11 of the single-chip microcomputer 1 for processing after demodulation and A / D conversion through the MII / RMII interface. It can be a chip, such as YT8512C, etc., or an analog-digital hybrid circuit. The RS485 interface chip 24 is similar in function to the network interface chip 22, mainly used to establish a connection with the industrial server 4, and transmit the operating state signal data of the industrial server 4 to the network isolation chip 23 through hardwiring or serial port communication. The RS485 interface chip 24 can adopt MAX485, SN65HVD485, ADM485, etc. The network isolation chip 23 is used to send the data information transmitted by the RS485 interface chip 24 to the central processing unit 11 for analysis and processing in an electrically isolated state, and can adopt NSi83085, NSi83086, etc. This application ensures the security, continuity, and stability of data transmission by setting two communication channels.

[0032] In one embodiment, the structure of the single-chip microcomputer 1 is as Figure 2 shown, and further includes an internal memory 12. The internal memory 12 is connected to the central processing unit 11, and can save the operating state data of the industrial server 4 transmitted therein for subsequent retrieval. The single-chip microcomputer 1 further includes a communication management unit 13. One end of the communication management unit 13 is connected to the central processing unit 11, and the other end of the communication management unit 13 is connected to the industrial server 4. Among them, the communication management unit 13 establishes a connection with the industrial server 4 wirelessly, and directly transmits the operating state data in the industrial server 4 to the central processing unit 11 for processing. The wireless methods include, but are not limited to, Bluetooth, WiFi, radio frequency, etc. The communication management unit 13 can adopt nRF24L01, QCA2066, QCA6391, WCN6750, WCN6856, WCN7851, etc. The central processing unit 11 can also compare the data collected by the communication management unit 13 with the data transmitted by the chip connection module 2 to verify the accuracy of the data.

Corresponding sensors can be connected through these interfaces. The temperature sensor 71, the humidity sensor 72, and the vibration sensor 73 are respectively used to collect the temperature, humidity, and vibration information of the industrial server 4. The normal temperature, humidity, and vibration ranges of the industrial server 4 during operation are stored in the internal memory 12. The central processor 11 can retrieve these range information and compare it with the information transmitted by the sensors. When an abnormality is determined, the alarm module 3 is used to remind the operation and maintenance personnel to reduce losses.

[0034] In one embodiment, please refer to Figure 3 for details. The device further includes a power supply module 5 and a crystal oscillator module 6.

When it is green, it means the device is running normally. When it is red, it means there is an abnormality in the device itself, such as the data collected by the communication management unit 13 is too different from the data transmitted through the chip connection module 2. When it is gray, it means the device has not been started, such as not being powered on or not being connected to the power supply module 5; the second status light unit 312 is used to indicate the communication status between the hardware redundant watchdog device and the industrial server 4 (here refers to the communication status when establishing a connection with the industrial server 4 through the chip connection module 2). When it is gray, it means the communication is abnormal. When it is green, it means the communication is normal; the third status light unit 313 is used to indicate the running status of the industrial server 4. When it is green, it means the industrial server 4 is running normally.
