[0002] A photoelectric encoder, also known as a photoelectric encoder, compiles and converts signals or data into a form that can be communicated, transmitted, and stored. It converts angular displacement into an electrical signal. This device is widely used in satellite communication antennas. As an angle calibration device, it provides antenna operators with current antenna angle information and is crucial for proper antenna rotation. Modifying and configuring this device's parameters primarily relies on pre-shipment configuration by the manufacturer, which is relatively costly. In the event of equipment failure, the equipment must be sent back for repair, which can be time-consuming. Therefore, a simple tooling design is desired to facilitate this operation.

[0003] The photoelectric encoder uses the CAN bus communication protocol to exchange information with the lower computer. The CAN bus uses twisted-pair cables to transmit signals, which requires a 120-ohm matching resistor to be installed at each end of the loop. Utility Model Content

[0022] like Figure 1As shown, the multi-adaptive photoelectric encoder debugging tool includes four test lines for connecting to the photoelectric encoder to be debugged, and a power supply part and an analyzer part respectively connected to the four test lines through a connection board. The power supply part is a DC regulated power supply for providing a 24V operating voltage for the photoelectric encoder. The analyzer part includes a Kvaser Leaf Light V2 bus analyzer. One end of the Kvaser Leaf Light V2 bus analyzer is connected to a computer host via a USB interface, and the other end is connected to the connection board through a first serial port and then communicated with the four test lines to ensure CAN communication between the analyzer part and the photoelectric encoder.

[0023] Specifically, port 1 of the four-port test line is used for CANH communication, port 4 is used for CANL communication, port 2 is used to connect the live wire, and port 3 is used to connect the ground wire. There are a total of 9 terminals on the serial port interface of the first serial port, among which terminal 2 is connected to a wire for CANH communication, and terminal 7 is connected to another wire for CANL communication. The two wires are respectively connected to port 1 for CANH communication and port 4 for CANL communication of the four-port test line through the interface of the adapter board to ensure CAN communication between the analyzer part and the photoelectric encoder; the positive and negative poles of the DC regulated power supply are respectively connected to a power line, which is connected to port 2 for connecting the live wire and port 3 for connecting the ground wire of the four-port test line through the adapter board to ensure the power supply of the photoelectric encoder.

[0024] The negative and positive poles of the DC regulated power supply are respectively connected to the a and b interfaces of the adapter board, and are connected to the 3th port for connecting the ground wire and the 2th port for connecting the live wire of the four-port test line through the 1 and 2 interfaces of the adapter board to ensure the power supply of the photoelectric encoder; the serial port interface of the first serial port has a total of 9 terminals, among which terminal 2 is connected to a wire for CANH communication, and terminal 7 is connected to another wire for CANL communication.

[0025] The photoelectric code disk is an azimuth code disk, a pitch code disk, a cross code disk or a polarization code disk.

[0026] The method for debugging using the multi-adaptive photoelectric encoder debugging tool of the utility model is as follows:

[0027] Optical encoders are categorized as azimuth, elevation, cross, and polarization encoders, depending on their intended use. Each encoder requires different parameter settings. To debug an optical encoder, a DC regulated power supply provides 24V DC operating voltage. After opening the Kvaser debugging software on a computer, modify the encoder ID, baud rate, and other information as needed. To begin, connect the pre-assembled four-port test lead to the optical encoder to be debugged. The power cables from ports 2 and 3 of the four-port test lead are connected to the DC regulated power supply via an adapter board. The CANH and CANL signal lines from ports 1 and 4 of the four-port test lead are connected to terminals 2 and 7 of the first serial port connected to the Kvaser Leaf Light V2 bus analyzer, respectively, via the adapter board. Turn on the DC regulated power supply and provide 24V DC power to the optical encoder. Once the optical encoder receives the operating voltage, it communicates with the Kvaser Leaf Light V2 bus analyzer via the two test cables connected to CANH and CANL. This information can then be queried and modified using the Kvaser debugging software on a computer. Using Kvaser debugging software on a computer, you can modify the ID number, baud rate, and other information of the optical encoder and send it to the optical encoder for storage. Kvaser debugging software can also be used to generate a parameter modification record. The next time the same optical encoder needs debugging, you can directly call up the modification record without repeating the operation. Example

[0028] like Figure 2 As shown, the multi-adaptive photoelectric code disk debugging tooling, based on Example 1, is connected to the connection board in parallel with the four-port test line. A four-port aviation plug test line with a test port function arrangement different from that of the four-port test line is used to realize the switching connection use of different device interfaces. A second serial port is also provided between the connection board and the four-port test line and the four-port aviation plug test line, which is used to allow the current provided by the power supply part to power the four-port test line and the four-port aviation plug test line respectively, and to allow the analyzer part to communicate with the devices connected to the four-port test line and the four-port aviation plug test line respectively.

[0029] The second serial port is a 9-port serial port, of which port 1 is used to connect the ground wire, port 2 is used to connect the live wire, port 7 is used for CANH communication, and port 8 is used for CANL communication. Ports 1 and 2 are respectively connected to interfaces 1 and 2 of the adapter board to provide working voltage, and ports 7 and 8 are respectively connected to interfaces e and f of the adapter board to realize information transmission of CAN communication;

[0030] Port 1 of the four-port aviation plug test cable is used to connect the ground wire, port 2 is used to connect the live wire, port 3 is used for CANH communication, and port 4 is used for CANL communication. Ports 1 and 2 are connected to interfaces 1 and 2 of the adapter board to provide working voltage, and ports 3 and 4 are connected to interfaces e and f of the adapter board to realize information transmission of CAN communication.

[0031] The method for debugging using the multi-adaptive photoelectric encoder debugging tool of the utility model is as follows:

[0032] When debugging the optical encoder, a DC regulated power supply provides a 24V DC operating voltage. After opening the Kvaser debugging software on a computer, modify the encoder's ID number, baud rate, and other information as needed. To do this, first connect the pre-assembled four-port test cable to the optical encoder to be debugged. The power cables from ports 2 and 3 of the four-port test cable are connected to the DC regulated power supply via an adapter board. The CANH and CANL signal cables from ports 1 and 4 of the four-port test cable are connected to terminals 2 and 7 of the first serial port connected to the Kvaser Leaf Light V2 bus analyzer, respectively, via the adapter board. Then, turn on the DC regulated power supply and provide 24V DC power to the optical encoder. Once the optical encoder receives the operating voltage, it communicates with the Kvaser Leaf Light V2 bus analyzer via the two test cables connected to CANH and CANL. This information can then be queried and modified using the Kvaser debugging software on a computer. Using the Kvaser debugging software on a computer, the optical encoder's ID number, baud rate, and other information can be modified and transmitted to the optical encoder for storage. You can also use Kvaser debugging software to generate a parameter modification record table. The next time the same type of optical encoder needs to be debugged, you can directly call the modification record without repeating the operation.

[0033] If there are other devices similar to the encoder that need to be debugged, but the test port function arrangement is different from the above four-port test line interface, use a four-port aviation plug test line with the same test port function arrangement to connect and test according to the above method.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
