Aircraft landing speed test system based on invisible laser

The utility model provides an aircraft landing speed test system based on invisible laser, comprising an upper computer used for carrying out real-time processing and analysis on test data through test software to obtain a speed measurement result; the master control device is used for controlling the laser transmitting and receiving device and is communicated with the upper computer through an access network; and the multiple sets of laser transmitting and receiving devices are used for collecting test data when the aircraft lands and sending the test data to the upper computer through the access network. The device is high in test precision, and overcomes the defect that the test precision of a laser speed measurement method is easily influenced by environmental factors; in addition, the system does not need to be fixedly installed, is low in cost, small in size of test equipment, capable of being rapidly laid and supporting local and remote control modes, convenient and safe, and greatly reduces manpower a
