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.
