Abstract
Description
Technical Field
[0001] This utility model relates to an electronic product debugging device based on circuit multiplexing, belonging to the field of electronic product debugging technology. Background Technology
[0002] During the commissioning of products such as rate / accelerometers, the products need to be mounted on a turntable or indexing head plane, and the signals are exported from the turntable via slip rings. Since the parameters of the products need to be adjusted during commissioning, in a typical commissioning environment, four products are installed at a time, each requiring three pairs of bus signals. If all the required bus signals are exported, 24 slip ring interfaces are needed. The existing number of slip rings on the turntable cannot meet the requirements, necessitating either increasing the number of slip ring ports or removing the products for parameter adjustment. Increasing the number of slip ring ports involves modifying the existing equipment, which is uneconomical and time-consuming. While removing the products for parameter adjustment avoids modification, repeated disassembly and reassembly negatively impacts the product's appearance and commissioning efficiency. The existing commissioning equipment has insufficient bus interfaces for commissioning, requiring multiple plug-and-play connections to different parameter adjustment ports; adding bus ports also involves modifying the testing equipment.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] An electronic product debugging device based on line multiplexing includes an external controller, a connecting cable, and an internal controller. The external controller sends a channel selection signal and a single bus signal to the connecting cable via a switch or a control signal from the test equipment. The internal controller receives the channel selection signal and bus signal from the external controller via the connecting cable and connects the bus signal to the corresponding channel according to the channel selection signal.
[0020] The connecting cable is used to connect the external controller of the turntable to the internal controller of the turntable. The connecting cable is typically integrated into the product test cable as part of the product test cable, and can connect to the inside and outside of the turntable via turntable slip rings or similar means.
[0021] like Figure 1 As shown, the external controller of the turntable consists of a turntable external controller housing 1, multiple indicator lights 2, multiple buttons 3, a signal processing board 5, a switch board 4, an indicator board 6, and a cable assembly. The multiple indicator lights 2 and buttons 3 are respectively installed on the upper surface of the turntable external controller housing 1. The switch board 4 is installed on the upper inner surface of the turntable external controller housing 1 and corresponds one-to-one with the multiple buttons 3. The indicator board 6 is installed on the inner side of the turntable external controller housing 1 and corresponds one-to-one with the multiple indicator lights 2. The signal processing board 5 is installed on the lower inner surface of the turntable external controller housing 1. The cable assembly is connected to the signal processing board 5 via connectors.
[0022] Indicator light 2 is used to indicate the currently selected channel number and also to display the currently used control mode; button 3 is used to select the channel number to be connected or to switch the control mode; switch board 4 is used to send switch signals to the signal processing board; indicator board 6 is used to install indicator lights or display screens. The indicator board unpacks the signals packaged by the signal processing board and lights up the corresponding indicator lights. The control signal indicator lights are directly controlled by the signal processing board; signal processing board 5 packages the signals from the switch board, parameter adjustment bus, and channel selection bus and transmits them to the controller inside the turntable via connecting cables.
[0023] The signal processing board 5 switches between two modes: test equipment bus control and switch control. When using test equipment bus control, the signal processing board converts the test equipment bus selection signal into a signal received by the controller inside the turntable. When using switch control, the board converts the channel selected by the switch into a signal received by the controller inside the turntable.
[0024] The indicator board 6 converts the signals received by the turntable controller and illuminates the corresponding indicator lights or displays them on the screen. The power supply for the indicator board 6 comes from the power supply to the turntable controller. Thus, the indicator board detects and displays the signals sent by the signal processing board to the turntable controller.
[0025] The cable assembly consists of a test equipment bus connection port, a power cord, and a parameter adjustment bus port.
[0026] The signals transmitted by the connecting cable include bus strobe signals, debug bus signals, power supply, or, as needed, verification signals and status signals.
[0027] like Figure 2 As shown, the turntable internal controller consists of a turntable internal controller housing 7, multiple turntable internal controller indicator lights 8, multiple sockets 9, a socket board 10, a turntable internal controller signal processing board 11, and a turntable internal controller indicator board 12. The turntable internal controller indicator lights 8 and sockets 9 are respectively installed on the upper surface of the turntable internal controller housing 7. The socket board 10 is installed on the upper inner surface of the turntable internal controller housing 7 and corresponds one-to-one with the multiple sockets 9. The turntable internal controller indicator board 12 is installed on the inner side of the turntable internal controller housing 7 and corresponds one-to-one with the multiple turntable internal controller indicator lights 8. The turntable internal controller signal processing board 11 is installed on the lower inner surface of the turntable internal controller housing 7. The cable assembly is connected to the turntable internal controller signal processing board 11 through connectors, and the other end of the cable is connected to the turntable external controller.
[0028] The turntable controller indicator light 8 is used to indicate the currently selected channel number and also to display the currently used control mode; the socket 9 is used to transmit signals to the corresponding port; the socket board 10 is used to install the socket; the turntable controller indicator board 12 is used to install indicator lights or displays and is directly controlled by the signal processing board; the turntable controller signal processing board 11 unpacks the signals transmitted from the connecting cable to the turntable controller's parameter adjustment bus and channel selection bus and distributes and displays them through the socket board and indicator board.
[0029] The turntable internal controller signal processing board 11 is used to send the bus data packaged by the turntable external controller to the corresponding bus socket.
[0030] The turntable controller indicator panel 12 is used to indicate the currently connected port number and operating status.
[0031] The socket board is used to connect the parameter adjustment plug on the product. The connecting cable is connected to the socket in the controller housing inside the turntable and then connected to the signal processing board via a wire.
