If the communication network connection path is normal, control parameter data transmission is performed.

The control center obtains the test program, parameter setting files and test process files; Using a symmetric encryption algorithm, encrypting the detection program, parameter setting file and detection process file to obtain an encrypted detection program, an encrypted parameter setting file and an encrypted detection process file; Construct a hierarchical dynamic structure for parallel transmission of multiple data between the board fault detection equipment and the control center; The encrypted test program, encrypted parameter setting file and encrypted test process file are transmitted in parallel according to the hierarchical dynamic classification structure; The board fault detection device uses a decryption key to decrypt the encrypted detection program, the encrypted parameter setting file and the encrypted detection process file to obtain the detection program, the parameter setting file and the detection process file; The board fault detection device compares the versions of the detection program, parameter setting file and detection process file to determine whether they are the versions used by the board fault detection device. If so, no processing is performed. If not, a signal is sent to the control center, and the control center retransmits the detection program, parameter setting file and detection process file of the version used by the board fault detection device.

[0018] This solution sets up a network construction module, a communication verification module, a transmission structure construction module and a parallel transmission module. In multi-data transmission, the data is classified, the data transmission time is estimated in each classification, and then the time the data occupies the network channel is estimated, and then the idle time of the network channel is predicted, so as to allocate a network channel and a transmission time point for each data, avoid data transmission congestion, improve transmission efficiency, detect anomalies in the constructed local area network, and carry out targeted repairs for anomalies, thereby ensuring the normal network of the constructed local area network and avoiding transmission obstruction.

[0020] Reference Figure 3 As shown, the communication network connection status between the verification board fault detection device and the control center specifically includes: The control center generates a verification message, which is a fixed process inspection program, parameter setting file and inspection process file; The communication verification module transmits the verification message through the network transmission software installed in the control center, and the network transmission software transmits the verification message to the corresponding board fault detection device according to the IP address of each detection module of the board fault detection device; Determine whether the detection module in the board fault detection device operates according to the parameters defined by the detection program, parameter setting file and detection process file of the fixed process. If so, the network connection between the control center and the detection module is normal; if not, the network connection between the control center and the detection module is abnormal; When the board fault detection device traverses all detection modules, if the connection between the control center and each detection module in the board fault detection device is normal, the network connection between the board fault detection device and the control center is normal; if not, the network connection between the board fault detection device and the control center is abnormal.

[0021] The purpose of communication verification of the network connection status between the board fault detection device and the control center is to find out that there is an abnormal network connection between the board fault detection device and the control center. The method adopted is to use the fixed process detection program, parameter setting file and detection process file to transmit to the board fault detection device. The board fault detection device will perform the fixed process operation according to the data, and then judge whether the operation is consistent with the fixed process. It can be judged whether there is an abnormality in the data transmission, and then judge whether the network connection between the board fault detection device and the control center is abnormal. Reference Figure 4 As shown, the communication network connection status between the repair board fault detection device and the control center specifically includes: Obtain a detection module to be repaired for abnormal network connection between the control center; Get the abnormal IP address of the detection module to be repaired; Reassign a repair IP address to the detection module to be repaired; In the network transmission software, delete the original IP address corresponding to the detection module to be repaired, re-enter the repair IP address, and connect the detection module to be repaired and the control center to the same local area network; The communication verification module verifies the network connection between the detection module to be repaired and the control center. If the network connection is normal, the repair is completed. If not, a new repair IP address is continuously reallocated to the detection module to be repaired until the network connection is normal.

[0022] Repairing the network connection between the abnormal board fault detection device and the control center instead of rebuilding the entire network can reduce the workload of the operation and at the same time, enhance the targetedness of the operation.

[0023] Reference Figure 5 As shown, the hierarchical dynamic hierarchical structure for constructing multi-data parallel transmission between the board fault detection device and the control center specifically includes: Obtaining the file size of at least one detection program, parameter setting file, and detection process file to obtain a size range of the transmission data; Dividing the size range of the transmitted data at equal intervals to obtain at least one size classification range; Classify the test procedures, parameter setting files and test process files into size classification ranges according to the file size; Obtain at least one network channel of the local area network, obtain the transmission speed of the network channel, and obtain the maximum number of data transmitted simultaneously by the network channel as the limit number; Allocate network channels for data within the size classification range; Estimate the transmission time of the network channel used by data within the size classification range, and estimate the occupancy rate of the network channel based on the transmission time and the number of restrictions; When the network channel is idle, untransmitted data within the size classification range is allocated in the network channel; When all data within the size classification range are assigned network channels, the network channels to which the data are assigned and the allocation time points are recorded as a hierarchical dynamic grading structure for parallel transmission of multiple data.

[0024] Classify the data according to its size. Because there are many data, it takes a lot of time to predict the transmission time of each data. Therefore, classify the data and consider the data in each class as the same type, which can reduce the number of judgments. The transmission time is used to determine the end time of the network channel transmitting a single data, and the limit number is the maximum number of data that the network channel can transmit simultaneously. Therefore, when the transmission of a single data ends, new data can be allocated to the network channel for transmission. In this way, all data can be allocated to the network channel without causing congestion. Therefore, the network channel and allocation time point to which each data is allocated can be used as a hierarchical dynamic structure for the parallel transmission of multiple data.

[0025] Reference Figure 6 As shown, the encrypted detection program, encrypted parameter setting file and encrypted detection process file are transmitted in parallel according to the hierarchical dynamic structure, specifically including: Obtaining at least one test program, parameter setting file, and test process file; Obtaining a network channel and an allocation time point corresponding to one of the target data in the hierarchical dynamic hierarchical structure of multi-data parallel transmission, recorded as a first network channel and a first allocation time point; At a first allocation time point, using a first network channel to transmit target data; When the target data traverses the inspection program, parameter setting file and inspection process file, the data transmission is completed.

[0028] The conversion of the communication protocol can convert the data into the same form of the communication protocol used by the board fault detection device. Because in actual detection, the purchased board fault detection devices come from various manufacturers, and the board fault detection devices use different systems. Therefore, compatibility conversion is required, otherwise the data cannot be universal.

[0029] The data update module updates the detection program, parameter setting file and detection process file in the board fault detection device, including the following steps: The data update module determines whether the storage space of the board fault detection device is sufficient. If so, the detection program, parameter setting file and detection process file are directly stored. If not, the stored historical detection program, parameter setting file and detection process file are deleted until the storage space of the board fault detection device is sufficient.

If the network connection path is normal, data transmission is performed. If the network connection path is abnormal, the network construction module repairs the network connection between the board fault detection device and the control center. Step 3: The data acquisition module obtains the detection program, parameter setting file and detection process file from the control center; Step 4: The data encryption module uses a symmetric encryption algorithm to encrypt the detection program, parameter setting file and detection process file to obtain an encrypted detection program, an encrypted parameter setting file and an encrypted detection process file; Step 5: The network interface compatibility module sets a compatible communication network interface to convert the communication protocol.

If so, no processing is performed. If not, a signal is sent to the control center, and the control center retransmits the detection program, parameter setting file and detection process file of the version used by the board fault detection device; Step ten: The data update module updates the detection program, parameter setting file and detection process file in the board fault detection device.
