specific Embodiment approach 1

[0034] Specific implementation mode 1. Combination figure 1 Describe this specific embodiment, the upper and lower computer communication method of secondary platform motion control,

[0035] Taking the upper computer as the client and the communication node of the lower computer as the server, the communication process initiated by the client is realized by the following steps:

[0036] Step 1. The client receives the user's operation instruction, converts it into a format that the server can recognize, and downloads it to the server through the Socket interface, and then waits for the returned data;

[0037] Step 2. The server accesses the client’s operation instructions and adds them to the instruction receiving buffer queue; the instruction interpretation task takes out the instructions from the instruction receiving buffer queue and executes the corresponding software and hardware operations. After the operation is completed, the execution result is added to the data send...

Abstract

The invention discloses a method and device for communication between an upper computer and a lower computer under the control of secondary platform movement and relates to a communication method and device. The method and device aim to solve the problem that a traditional method for communication between the upper computer and the lower computer under the control of secondary platform movement is poor in real-time performance. A communication node of the upper computer and a communication node of the lower computer are in communication through a TCP communication protocol. The communication node of the lower computer conducts communication with a single-chip microcomputer through a serial port. Since a large number of communication instructions are used, a communication protocol and a communication device of an application layer are defined. When the upper computer sends an instruction to the lower computer and the single-chip microcomputer, the upper computer sends data to the communication node of the lower computer through a TCP channel, the communication node of the lower computer sends information of the application layer to the single-chip microcomputer through the serial port, and the single-chip microcomputer executes a corresponding function according to the instruction. The method and device are suitable for communication between the upper computer and the lower computer under the control of secondary platform movement.

Description

technical field [0001] The invention relates to a communication method and device. Background technique [0002] In modern society, a platform with high flatness is often required. For example, in full-physics simulation experiments such as space rendezvous and docking, ground measurement, navigation, network communication, and formation control, it is necessary to support the entire ground simulator and provide a basic platform for ground simulation experiments. ; Provide platform support for physical simulation tests such as formation satellite ground test verification and control algorithm verification analysis. Since the platform may be in a tilted state due to the unevenness of the large-area horizontal base when it is moving or stationary, it is not conducive to providing a working platform as horizontal as possible for the load to ensure accurate docking, so the platform needs to be able to be used in both stationary and moving states Fast and precise leveling to ens...
