Problems solved by technology

[0005] However, in the actual application process, the remote receiver has many disadvantages. If different functions are realized, the hardware and firmware of the main control card need to be modified. The system expandability is poor, the processing efficiency of each board is low, and PCB resources are wasted. , and the external signal has great interference to the board, especially the crosstalk between the digital signal and the analog signal

Abstract

The invention belongs to the technical field of civil aviation, and provides a remote receiver and method of a multi-point positioning system based on a CPCI architecture. The remote receiver includes a radio frequency signal receiving card, a signal processing card, a main control card, a clock card, a monitoring card and a power module card. The radio frequency signal receiving card, the signal processing card and the main control card are connected in sequence, and the clock card is respectively connected to the radio frequency signal The receiving card is connected with the signal processing card, the monitoring card is connected with the RF signal receiving card, the signal processing card and the clock card respectively through the PCI bus, the power module card is connected with the RF signal receiving card, the signal processing card and the main control card respectively, the signal processing card It is connected with the main control card through the PCI bus. The remote receiver and method of the multi-point positioning system based on the CPCI architecture of the present invention can improve the expansion performance, data processing efficiency and reliability performance of the remote receiver, and avoid external signal interference.

Description

technical field [0001] The invention relates to the technical field of civil aviation, in particular to a remote receiver and method of a multipoint positioning system based on CPCI architecture. Background technique [0002] The multi-point positioning system provides a new technology method different from the traditional surface surveillance radar for the airport scene. Its base station is flexible in layout, low in cost, and can obtain comprehensive aircraft information, and realize comprehensive surveillance coverage of the entire active area. [0003] The working mechanism of multi-point positioning monitoring is: multi-point positioning remote receiver is a front-end monitoring sensor, and its most important function is to receive the signal sent by the target, and accurately record the arrival time of the signal, and then send the aircraft response information to the multi-point Positioning system central processing station for processing. [0004] The remote receive...
