Description

A Method for Simultaneously Testing Multiple Electronic Products

technical field

The invention relates to the field of electronic product testing, in particular to a method for simultaneously testing multiple electronic products.

Background technique

Generally, electronic products need to be written and tested during production. Usually, the test computer is connected to the product, and the test software is used to set parameters and test the product, such as writing the MAC address (device physical address) and checking the MAC address.

The existing writing and testing methods are usually one-to-one connection for writing or testing, that is, one testing computer can only operate one product at a time, which is low in efficiency and high in cost.

Contents of the invention

The purpose of the present invention is to provide a method for testing multiple electronic products at the same time, which solves the problem of low writing and testing efficiency and high equipment cost due to the current one-to-one single operation for writing or testing electronic products.

In order to solve the problems referred to above, the technical scheme that the present invention takes is:

A method for simultaneously testing multiple electronic products, comprising the following steps:

Step 1, configure a test computer with test software and a switch with VLAN management function, the switch has 1+n ports;

Step 2, the port 1 in the switch is connected to the test computer, and the remaining n ports are respectively connected to n devices to be tested, and the switch configures a corresponding VLAN for each port in the n ports;

Step 3, set the management addresses of all the devices under test to the same primary IP address, and use telnet for configuration management;

Step 4, the test computer simultaneously sends out n packets with different destination IP addresses, and after the packets are encapsulated, they are sent to the network card of the test computer;

Step 5, the test computer monitors the network card of the test computer through software. If the destination IP address of the message sent is one of the n IP addresses, the destination IP address of the message is changed to the main IP address, and the data link in the message The corresponding VLAN identification field is added to the header of the road layer, and then sent to the switch by the network card of the test computer;

Step 6, the switch distributes the message to one or more of the n ports according to different VLANs. Before the device under test receives the message, the port of the switch removes the VLAN field in the message, and each device under test The received packets are all packets with the destination IP address as the primary IP address, and have no VLAN ID;

Step 7, when the device under test responds to the test computer, it sends a message whose source IP address is the main IP address;

Step 8: When the switch receives the messages of the devices to be tested, it adds corresponding VLAN fields before the messages, and then sends them to the network card of the test computer through port 1 of the switch.

Step 9: After the network card of the test computer receives the response message, the software in the test computer will modify the source IP address of the message to corresponding n different IP addresses according to different VLAN IDs, and remove the VLAN ID in the message , and then receive and decapsulate by the test computer to complete the communication process of one computer corresponding to multiple devices.

A further technical solution is that the switch has 9 ports, port 1 is connected to the test computer, and the remaining 8 ports are respectively connected to 8 devices to be tested.

A further technical solution is that the main IP address is set to 192.168.1.1, and the destination IP addresses corresponding to the eight devices to be tested are 192.168.1.2...192.168.1.9 respectively.

The beneficial effect produced by adopting the above-mentioned technical scheme is that: when the test software on the test computer sends out test instructions in the present invention, multiple groups of different messages can be simultaneously sent out for multiple products, and converted into receivable data by the software to reach the device under test , to achieve mutual communication, so as to achieve the effect that a single computer can operate multiple devices under test at the same time and improve production efficiency.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Fig. 1 shows an embodiment of a method for simultaneously testing multiple electronic products of the present invention: a method for simultaneously testing multiple electronic products comprises the following steps:

Step 1, configure a test computer with test software and a switch with VLAN management function, the switch has 1+n ports;

Step 2, the port 1 in the switch is connected to the test computer, and the remaining n ports are respectively connected to n devices to be tested, and the switch configures a corresponding VLAN for each port in the n ports;

Step 3, set the management addresses of all the devices under test to the same main IP address (the IP addresses are generally the same when the devices are mass-produced), and use telnet for configuration management;

Step 4, the test computer simultaneously sends out n packets with different destination IP addresses, and after the packets are encapsulated, they are sent to the network card of the test computer;

Step 5, the test computer monitors the network card of the test computer through software. If the destination IP address of the message sent is one of the n IP addresses, the destination IP address of the message is changed to the main IP address, and the data link in the message The corresponding VLAN identification field is added to the header of the road layer, and then sent to the switch by the network card of the test computer;

Step 6, the switch distributes the message to one or more of the n ports according to different VLANs. Before the device under test receives the message, the port of the switch removes the VLAN field in the message, and each device under test The received packets are all packets with the destination IP address as the primary IP address, and have no VLAN ID;

Step 7, when the device under test responds to the test computer, it sends a message whose source IP address is the main IP address;

Step 8: When the switch receives the messages of the devices to be tested, it adds corresponding VLAN fields before the messages, and then sends them to the network card of the test computer through port 1 of the switch.
