[0044] During the battery production process, the torque wrench, the factory-level MES, and the line-level MES are respectively connected to the host computer. The host computer, the factory-level MES, the line-level MES, and the torque wrench cooperate with each other to ensure the efficiency and quality of battery production.

[0045] First, the functions of the host computer, the factory-level MES, the line-level MES, and the torque wrench are described.

[0046] The torque wrench is used to receive the task parameters issued by the host computer, perform assembly operations such as tightening the bolts of the battery based on the task parameters issued by the host computer, and feed back the detailed data of each operation to the host computer.

[0047] The line-level MES is used for the management and monitoring of one or several production lines. The line-level MES is connected to the equipment on the production line, collects the production data of the equipment in real time, and sends the production data to the factory-level MES.

[0048] The factory-level MES is the management core of battery manufacturing production and is responsible for analyzing and managing the data of all line-level MESs.

[0049] During the battery production process, the host computer may malfunction. When the host computer malfunctions, the inspection personnel need to check item by item whether the IP of the host computer is correct, whether the communication connections between the line-level MES, the factory-level MES and the host computer are normal, whether the firewall is turned on, and the IP address of the torque wrench. Each step of the above inspection operations requires manual operation by the inspection personnel, which takes a long time and affects the production efficiency.

[0050] Based on this, the present application provides a host computer self-checking method, in which the host computer executes at least one self-checking step without manual participation, thereby saving the time for fault detection and improving the production efficiency.

[0051] Figure 1 It is a flowchart for implementing the host computer self-checking method provided by the present application, as Figure 1 shown, the method includes:

[0052] S101. The host computer executes at least one self-checking step.

[0053] In some embodiments, the host computer can perform at least one self-check step when the host computer reports an error. Among them, the host computer reports an error in the event of a failure.

[0054] In other embodiments, the host computer can also perform at least one self-check step when the product model is switched on the production line.

[0055] Among them, the number of self-check steps is 4, which are respectively:

[0056] Self-check step 1: The host computer obtains its own first IP address.

[0057] Self-check step 2: The host computer establishes a connection with at least one MES and determines whether each MES is abnormally connected.

[0058] Among them, at least one MES includes a factory-level MES and a line-level MES.

[0059] Self-check step 3: The host computer obtains the status information of the firewall and determines whether the firewall is turned on.

[0060] Self-check step 4: The host computer detects the second IP address of the torque gun connected to the host computer.

[0061] In some embodiments, the number of torque guns is greater than or equal to 1. In self-check step 4, the host computer detects the second IP address of each torque gun connected to the host computer.

[0062] The embodiments of the present application do not limit the order of the above 4 self-check steps.

[0063] S102. Based on the self-check results of at least one self-check step, the host computer performs a fault detection on the host computer.

[0064] Specifically, for self-check step 1, after the host computer obtains the first IP address, it determines whether the first IP address is correct. Then the self-check result is whether the first IP address is correct.

[0065] If the self-check result of self-check step 1 is that the first IP address is incorrect, the reasons for the host computer to report an error include that the first IP address of the host computer is incorrect.

[0066] For self-check step 2, the self-check result includes the self-check sub-results corresponding to each MES. For each MES, the self-check sub-result is that the MES is abnormally connected to the host computer or the MES is normally connected to the host computer.

[0067] If the self-check result of self-check step 2 includes that any MES is abnormally connected to the host computer, the reasons for the host computer to report an error include that the MES is abnormally connected to the host computer.

[0068] For self-check step 3, the self-check result is: the firewall is on, or the firewall is off.

[0069] If the self-check result of self-check step 3 is: the firewall is off, the reasons for the host computer to report an error include: the firewall is off.

[0070] For self-check step 4, after the host computer detects the second IP address of the torque wrench connected to the host computer, it determines whether the second IP address is correct, and the self-check result is: whether the second IP address of the torque wrench is correct.

[0071] If the self-check result of self-check step 4 includes that the second IP address of any torque wrench is incorrect, the reasons for the host computer to report an error include: this second IP address is incorrect.

[0072] This embodiment provides a method for self-checking a host computer. Among them, the host computer executes the self-check results of obtaining its own address, determining whether the factory-level MES and line-level MES are abnormally connected, determining whether the firewall is on, and detecting the second IP address of the torque wrench, and performs fault detection on the host computer based on the obtained self-check results of the self-check steps, without manual participation, thereby saving the time for fault detection and improving production efficiency.

[0073] As described above, in the self-check step of the host computer, the host computer needs to detect the first IP address of the host computer. Next, through Figure 2 The embodiment illustrates how to obtain the first IP address of the host computer.

[0074] Figure 2 This is the implementation flowchart of the host computer self-check method provided by the embodiment of the present application. As Figure 2 shown, obtaining the first IP address of the host computer can be achieved through the following steps:

[0075] S201. The host computer establishes a connection with a preset virtual server based on the User Datagram Protocol (UDP).

[0076] Specifically, the host computer sends a local address request message to the virtual server based on UDP.

[0077] Among them, the virtual server is a server predefined for providing the first IP address of the host computer.

[0078] S202. The virtual server sends the first IP address to the host computer.

[0079] Correspondingly, the host computer receives the first IP address sent by the virtual server.

[0080] After the host computer establishes a connection with the virtual server based on UDP, the host computer calls the getsockname function to enable the virtual server to send the first IP address to the host computer.

[0081] In some embodiments, the type of the first IP address of the host computer is an IPV4 address.

[0082] Specifically, the method for the host computer to obtain the first IP address can be implemented by the following Python code:

[0083] import socket

[0084] s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

[0085] try:

[0086] s.connect(('1.1.1.1', 80))

[0087] ip = s.getsockname()[0] finally

[0088] print("The local IP address is:", ip)

[0089] In the above code, the socket library is introduced to create a UDP socket. The function s.socket(('1.1.1.1', 80)) is used to create a temporary connection to the virtual server, enabling the host computer to obtain the first IP address of the local machine through the getsocketname function.

[0090] Among them, the virtual server can be a Domain Name Server (DSN). The address of the virtual server is: 1.1.1.1; the port number of the virtual server is: 80.

[0091] In this embodiment, the host computer can complete the operation of obtaining the first IP address of the local machine by executing the python code. Specifically, after the host computer establishes a connection with the virtual server, by executing the getsocketname function, the virtual server will send the first IP address to the host computer.

[0092] As described above, in the self-check step of the host computer, the host computer needs to determine the communication connection status of each MES in the factory-level MES and the line-level MES. Next, through Figure 3 The embodiment exemplarily illustrates how the host computer determines the communication connection status of each MES. Figure 3 This is the implementation flowchart of the host computer self-check method provided by the embodiment of the present application. AsFigure 3 As shown in Figure 3 , for each MES, the following steps can be used to determine whether the connection of the MES is abnormal.

[0093] S301. The host computer sends a connection establishment request to the MES based on TCP and the third IP address of the MES.

[0094] In some embodiments, the host computer sends a connection establishment request to the MES based on the third IP address and the port number of the MES to test the communication status between the host computer and the MES.

[0095] S302. The host computer determines whether the communication connection between the host computer and the MES is abnormal based on whether a response message sent by the MES is received within a preset time.

[0096] The response message is a message sent by the MES based on the connection establishment request, and the response message indicates that the communication connection between the host computer and the MES is normal.

[0097] Specifically, if the host computer receives the response message sent by the MES within the preset time, the host computer determines that the communication connection between the host computer and the MES is normal; if the host computer does not receive the response message sent by the MES within the preset time, the host computer determines that the communication connection between the host computer and the MES is abnormal.

[0098] In some embodiments, the method for the host computer to determine whether the communication connection between the host computer and the MES is abnormal can be implemented by the following Python code:

[0099] import socket

[0100] def test_connection(host, port):

[0101] try:

[0102] s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

[0103] s.connect((host, port))

[0104] print(f"Communication with the server {host}:{port} is normal.")

[0105] s.close()

[0106] except socket.error as e:

[0107] print(f"Failed to establish a connection with the server {host}:{port}: {e}")

[0108] test_connection('10.16.1.***',*****)

[0109] In the above code, the function test_connection(host, port) is defined to test whether there is an abnormality in the communication connection between the host computer and MES. Among them, host is the third IP address of MES, and port is the port number of MES.

[0110] It should be noted that for different MESs, the third IP address and port number are different.

[0111] Among them, the function test_connection is used to create a TCP socket (SOCK_STREAM), enabling the host computer to send a connection establishment request to the third IP address and port number of MES.

[0112] After determining whether there is an abnormality in the communication connection between the host computer and MES, the test_connection function is called to test the specified remote MES service.

[0113] In this embodiment, for each MES, the corresponding test_connection function of MES can be used to send a connection establishment request to MES, thereby determining whether there is an abnormality in the communication connection between the host computer and MES.

[0114] As described above, in the self-check step of the host computer, the host computer needs to determine the opening status of the firewall, and then through Figure 4 The embodiment exemplarily illustrates how the host computer determines the opening status of the firewall.

[0115] Figure 4 This is the implementation flowchart of the self-check method of the host computer provided by the embodiment of the present application. As Figure 4 shown, it can be described how the host computer determines the opening status of the firewall through the following steps.

[0116] S401. The host computer obtains the status information of the firewall through the command line tool of the windows system.

[0117] In some embodiments, the host computer can start the command line tool through the subprocess module in python to obtain the status information of the firewall.

[0118] S402. The host computer determines whether the firewall is open based on the status information of the firewall.

[0119] Specifically, the host computer determines whether there is an indication message for the firewall to be enabled in the status information of the firewall. If the status information of the firewall includes the indication message for the firewall to be enabled, the host computer determines that the firewall is enabled; if the status information of the firewall does not include the indication message for the firewall to be enabled, the host computer determines that the firewall is not enabled.

[0120] In some embodiments, the host computer can determine whether the firewall is enabled through the following Python code:

[0121] import subprocess

[0122] def is_firewall_enabled():

[0123] result = subprocess.run(['netsh', 'advfirewall','show', 'allprofiles'], stdout = subprocess.PIPE, text = True)

[0124] output = result.stdout

[0125] return "ON" in output.upper()

[0126] print("Whether the firewall is on:", is_firewall_enabled())

[0127] Among them, the subprocess module is used to execute command-line instructions. In the defined function is_firewall_enabled, the function subprocess.run is used to run the Windows network setting command netsh advfirewall show allprofiles to obtain the status information of the firewall.

[0128] If the status information of the firewall contains "ON", it is determined that the firewall is enabled. Among them, "ON" is the indication message for the firewall to be enabled. If the firewall is enabled, the self-check result returns True, and if it is not enabled, the self-check result returns False.

[0129] In this embodiment, the host computer obtains the status information of the firewall through the Windows command-line tool to determine whether the firewall is enabled based on the status information of the firewall.

[0130] As described above, in the self-check step of the host computer, the host computer needs to detect the second IP address of the torque wrench connected to the host computer, and then through Figure 5The embodiments exemplarily illustrate how the host computer detects the second IP address.

[0131] Figure 5 The flowchart of the implementation of the self-checking method of the host computer provided by the embodiments of the present application is shown as Figure 5 shown, and how the host computer detects the second IP address can be described through the following steps.

[0132] S501. The host computer allocates a cache area.

[0133] Among them, the cache area is used to store the second IP address.

[0134] S502. The host computer obtains multiple fourth IP addresses through a preset function.

[0135] Among them, the multiple fourth IP addresses include the second IP addresses of all torque guns.

[0136] In some embodiments, the preset function can be get_local_ip_addresses. Through this function, the fourth IP addresses of all network interfaces of the host computer can be obtained. The fourth IP addresses include the IP addresses of the devices connected to the host computer and the first IP address (local address) of the host computer. Among them, the devices connected to the host computer are at least one torque machine.

[0137] S503. The host computer determines the second IP address from all the fourth IP addresses.

[0138] Specifically, for each fourth IP address, the host computer determines whether the fourth IP address is the local address or an IP address of a non-first type; if the fourth IP address is not the local address and is an IP address of the first type, the fourth IP address is determined as the second IP address. If the fourth IP address is the local address or an IP address of a non-first type, it is determined that the fourth IP address is not the second IP address.

[0139] Among them, the first type of address is the IPv4 address.

[0140] S504. The host computer stores the second IP address in the cache area.

[0141] As described above, after each second IP address is determined, the second IP address is stored in the cache area.

[0142] In some embodiments, the host computer can detect the second IP address through the following python code (where the content after " / / " is the explanation of this line of code):

[0143]

[0144] In the above code, the fourth IP address of all network interfaces of the host computer is obtained through the psutil library. Among them, the function get_local_ip_addresses is used to traverse all network interfaces on the machine to obtain the fourth IP address of all network interfaces of the host computer. Moreover, a judgment is made on the fourth IP address. When the fourth IP address is the second IP address, the fourth IP address is stored in the cache area.

[0145] It should be noted that although the steps of the method in this application are described in a specific order in the accompanying drawings, this does not require or imply that these steps must be executed in this specific order, or that all the steps shown must be executed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution, etc.; or, the steps in different embodiments may be combined into a new technical solution.
