The utility model provides a CAN real-time measurement and control platform used for a loader electric drive system, which is composed of an inverted pendulum test platform, an angle encoder, a servo motor, a drive swing rod, a motion control card, a CAN bus module, a motor driver and a PC machine, the CAN bus module comprises two CAN nodes, the two CAN nodes are connected in series, the PC machine is in bidirectional connection with the motion control card, and the motor driver is connected with the motion control card. The input end of the motion control card is connected with the output end of the second CAN node through a PCI interface, the motion control card is in bidirectional connection with the motor driver, the motor driver is in bidirectional connection with the servo motor, the servo motor is in bidirectional connection with the inverted pendulum test platform, and the output end of the inverted pendulum test platform and the output end of the driving swing rod are connected with the input end of the angle encoder. And the angle encoder is bidirectionally connected with the first CAN node. According to the utility model, a scientific basis is provided for CAN network control and application of the loader electric drive system, and the loader electric drive system has significant use value and social and economic benefits.

The application provides a wide voltage PCI resistance load card, which comprises a PCI interface control chip, a D / A chip module and an FPGA chip; the PCI interface control chip is used for receiving read / write signals sent by a PCI bus interface and forwarding the read / write signals to a local bus according to a preset mode; the D / A chip module comprises a plurality of groups of D / A chip sets arranged in an array, and each group of D / A chip sets constitutes a resistance channel; the FPGA chip is used for receiving read / write signals from the local bus, determining chip control signals and chip read / write data corresponding to a target D / A chip set in the plurality of groups of D / A chip sets based on the read / write signals, and transmitting the chip read / write data to the target D / A chip set based on the chip control signals, so that the target D / A chip set changes with the air speed and outputs corresponding resistance values. The application can solve the technical problem that the working voltage of the PCI resistance load card in the prior art cannot meet the joint test requirement of a certain type of aircraft lever force automatic adjustment system.

The utility model discloses a kind of PCI interface wire rod supporting devices of anti-extraction PIN, including fixed frame, three fixed sleeves are fixed on the fixed frame outer wall, three The press bar is equipped in the fixed sleeve, three The press plate is fixedly arranged on the press bar, the press plate bottom is fixedly arranged with clamping frame, the fixed frame outer wall is equipped with two link grooves, two The link rod is equipped in the link groove.The utility model is through the unique structure design, realize the quick clamping fixation of supporting device and mainboard and the synchronous extrusion fixation of PCI interface wire rod.Operating personnel only need to press once, and positioning installation of mainboard and device can be completed simultaneously, and the stable support of wire rod is completed, avoid the cumbersome process that traditional device needs to be fixed first supporting structure in case, then wire rod is separately fixed, greatly shorten assembly time, significantly improve installation efficiency.
