Abstract

The invention relates to a method and a device for receiving and forwarding telemeter data of a semi-physical simulator, belonging to the aerospace field. The invention solves the problems of easy interference and high bit error rate in the wireless receiving process when the vibration test is carried out by using a traditional semi-physical simulation missile telemeter system. The method for receiving and forwarding the telemeter data of the semi-physical simulator comprises the steps of: fixing a telemeter data receiving and forwarding device on an on-missile information processor through a positioning hole, wherein the telemeter data receiving and forwarding device comprises an FPGA (Field Programmable Gate Array), a telemeter data receiving port circuit, a data forwarding port circuit and a storage unit, wherein the telemeter data receiving port circuit receives telemeter data of the on-missile information processor and transmits to the FPGA to be processed, and the data processed by the FPGA is stored in the storage unit; and when the data is completely received, and after a rotary stable stands still, the data forwarding port circuit forwards the data in the storage unit to a ground receiving device under the control of the ground receiving device so as to complete the receiving and the forwarding of the telemeter data.

Description

technical field [0001] The invention relates to a method for receiving and forwarding telemetry data and a device for receiving and forwarding telemetry data of a semi-physical simulation simulator, belonging to the field of aerospace. Background technique [0002] The telemetry system is the main component of the missile system test equipment, one of the basic technologies for data reception and forwarding, and plays a vital role in signal transmission. In the telemetry system, the development of the hardware-in-the-loop simulation simulator is very important. Due to the high cost of missiles, rockets, and spacecraft, the number of flight tests is limited, and it is impossible to conduct field test flights every time for debugging and performance testing of ground telemetry equipment. Therefore, it is very necessary for the research of the telemetry system to use the hardware-in-the-loop simulation technology to create a test environment similar to the actual arrow (bomb) ...
