Embodiment Construction

[0039] figure 1 It is the overall frame diagram of the monitoring equipment

[0040] 1. The core of this design adopts DSP module, FPGA module, network module and external interface;

[0041] 2. DSP module: mainly completes the data frame analysis and processing process;

[0042] 3. FPGA module: mainly complete the development of N uplink and downlink cache FIFO modules inside the FPGA, and the storage space size of each FIFIO: 8192*8bit;

[0043] 4. Network module: W5300 chip is used to complete the TCP protocol data transmission mode between the device and the upper computer application software;

[0044] 5. External interface: If the device is fixed inside the chassis, it uses 422 level transmission to communicate with the subordinate units. If it is inserted in the chassis, the PXI card insertion area will perform TTL level transmission with the subordinate units.

[0045] The technical scheme adopted in the present invention comprises the following steps:

Abstract

The invention discloses a data management method of a monitoring device based on network transmission, which mainly completes functions: 1. establish a communication relationship with a host computer in a network mode; 2. forward multi-channel subordinate unit data in a parallel mode. Specific implementation method: by automatically identifying the equipment number of the subordinate unit, recording the corresponding slot number, and establishing a corresponding table between the equipment number of the subordinate unit and the slot number, all the channel data of the subordinate unit and the application software of the upper computer are interactively distributed and forwarded based on the corresponding table , using this monitoring device, greatly improves the data management strategy. The invention has been successfully applied to the global master control station system, and has the characteristics of strong practicability, stable and reliable transmission.

Description

technical field [0001] According to the data transmission management requirements of the satellite navigation global operation and control system, the invention relates to a data management method for monitoring equipment based on network transmission, which mainly realizes the data transmission hub between multiple subordinate units in parallel and the upper computer application software, and improves the system Integration and data management strategies are applicable to the field of system products. Background technique [0002] There are multiple subordinate units in the chassis equipment of the global operation and control system. The monitoring equipment is the core data interaction hub of the entire system equipment. One is to receive various control commands from the upper computer application software and distribute them to the subordinate units; Forward to the upper computer application software. The current monitoring equipment uses a serial port to communicate w...
