Description

Technical Field

[0001] The present invention relates to a celestial resonance orbit judgment system, and in particular to a celestial resonance orbit system based on computer simulation, belonging to the technical field of computer simulation analysis. Background Art

[0002] In celestial mechanics, orbital resonance occurs when the revolution periods of the orbits of two celestial bodies are in a simple integer ratio relationship, and they are affected by periodic gravitational forces. This keeps their orbits stable in gravitational perturbations. If the orbits of three or more celestial bodies have integer resonance ratios with each other, such a resonance is called Laplace resonance. For example, the resonance ratios of the orbits of Jupiter's moons Ganymede, Europa, and Io are 1:2:4.

[0003] In order to simulate orbital resonance in celestial mechanics, it is very necessary to develop and design an application system based on functions such as intelligent simulation management. Summary of the Invention

[0004] The technical object of the present invention is to design a celestial resonance orbit judgment system with intelligent simulation management. Through this system, various functions of the system operation can be intelligently processed, and the simulation of the orbital resonance process is also included, making the entire system more intelligent and visual.

[0005] To achieve the above object, the technical solution adopted by the present invention is a celestial resonance orbit judgment system, which includes an upper and lower computer communication module, a process numerical simulation position module, and a moving trajectory display module; the above upper and lower computer communication module is connected to the process numerical simulation position module and the moving trajectory display module; the upper and lower computer communication module sends the control signal calculated by the upper computer to the lower computer, and at the same time controls the upload of the process numerical simulation movement parameters to the upper computer.

[0006] Furthermore, the process numerical simulation position and moving trajectory module includes two modes, namely, position display in the celestial resonance orbit process numerical simulation coordinate system and process numerical simulation moving trajectory display in the world coordinate system; the process numerical simulation position and moving trajectory module displays the position of the process celestial resonance orbit numerical simulation and the celestial resonance orbit moving trajectory in the form of a graph.

[0007] Furthermore, the lower computer communication module uses a wireless communication method based on TCP / IP to send the control signal calculated by the upper computer to the lower computer, and controls the upload of the process celestial resonance orbit numerical simulation movement parameters to the upper computer.

[0008] Further, after the power is turned on, the process numerical simulation position module and the moving trajectory display module start to run. First, the initialization of the DSP is completed. Then, all the LED indicators and the digital tubes are lit to implement the detection of the indicators and the digital tubes. Then, the data in channel 0 is retrieved for display. The scanning and the acquisition of key values are implemented by HD7279. When a key is pressed, the KEY pin of HD7279 outputs a low level. This pin is connected to CAP2 / QEP2 / IOPA4 of TMS320LF2407, and TMS320LF2407 will generate an external interrupt CAP2INT. After initializing 7279, the digital encoder subroutine is executed in a loop and the interrupt flag is detected. If there is an interrupt, the processing subroutine is executed to implement various functions such as input, function, data exchange with the DSP, and display.

[0009] Further, whenever a key is pressed, HD7279 will output a low level at the KEY pin, and CAP2 / QEP2 / IOPA4 detects the KEY pin of 7279 jumping from the state "high" to the state "low" to execute the interrupt subroutine.

[0010] Further, when entering the processing, the operation flag bit is locked, and the processing subroutine is called after judging the operation flag bit in the main program. After entering the subroutine processing, by judging the received value, it enters the corresponding module processing respectively. That is, when entering the module, corresponding action feedback is generated.

[0011] Further, by looping and querying the digital encoding subroutine to judge the left and right rotations of the digital encoding period, the device voltage, current, speed, and channel are adjusted accordingly.

[0012] Further, in the program, this 3-digit value is used as the tens digit of the channel value, and the units digit value of the channel is used as the specific address of the voltage, speed, indicator, and digital tube according to the size of the space required by each parameter, which can be implemented by calling the address processing subroutine.

[0013] Compared with the prior art, the present invention is a developed and designed one that can realize functions such as intelligent simulation management. The system is easy to operate and has a simple interface; the various modules are closely related and independent of each other, can reflect their respective characteristics, and are convenient for maintenance and adding new content.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] The technical solution adopted by the present invention is an astronomical resonance orbit judgment system, which includes an upper and lower computer communication module, a process numerical simulation position module, and a moving trajectory display module; the above-mentioned upper and lower computer communication module is connected to the process numerical simulation position module and the moving trajectory display module; the upper and lower computer communication module sends the control signal calculated by the upper computer to the lower computer, and at the same time controls the upload of the process numerical simulation moving parameters to the upper computer.

[0021] As Figures 1-5 shown, the system designed by the present invention is based on the wireless communication method of TCP / IP to send the control signal calculated by the upper computer to the lower computer, and control the upload of the process numerical simulation moving parameters to the upper computer.

[0022] The process numerical simulation position and moving trajectory module includes two display modes, namely, position display in the process numerical simulation coordinate system and process numerical simulation moving trajectory display in the world coordinate system; after entering the "process numerical simulation position and moving trajectory" interface, the position and moving trajectory of the process numerical simulation can be displayed in the form of a graph.

[0023] When the power is turned on, the main program starts to run. First, the initialization of the DSP (software initialization, I / O initialization) is completed. Then, all the LED indicators and digital tubes are lit to realize the detection of the indicators and digital tubes, and then the data in channel 0 is retrieved for display. The scanning and key value acquisition are realized by HD7279. When a key is pressed, the KEY pin of HD7279 outputs a low level, and this pin is connected to CAP2 / QEP2 / IOPA4 of TMS320LF2407. TMS320LF2407 will generate an external interrupt CAP2INT. After initializing 7279, the digital encoder subroutine is executed in a loop and the interrupt flag is detected. If there is an interrupt, the processing subroutine is executed to realize various functions such as input, function, data exchange with the DSP, and display.

[0024] Interrupt subroutine design:

[0025] The interrupt program is enabled to achieve input. Whenever a key is pressed, HD7279 will output a low level at the KEY pin, and CAP2 / QEP2 / IOPA4 detects the KEY pin of 7279 jumping from the state "high" to the state "low" to execute the interrupt subroutine. After setting the flag bit, when the main program runs to loop and detect each status bit, the processing program can be run.

[0026] When entering the processing, the operation flag bit is locked, so that the processing subroutine will be called after judging the operation flag bit in the main program. After entering the subroutine processing, by judging the received value, it enters the corresponding module processing respectively. That is, when entering the module, corresponding actions will be generated.

[0027] Subroutine 1: Digital encoder subroutine:

[0028] By looping and querying the digital encoding subroutine to judge the left and right rotation of the digital encoding period, so as to adjust the device voltage, current, speed and channels.

[0029] Subroutine 2: Call subroutine:

[0030] In the program, this 3-bit value is used as the tens digit of the channel value, and the units digit value of the channel is used as the specific address of the voltage, speed, indicator light, and digital tube according to the size of the space required by each parameter, which can be achieved by calling the address processing subroutine.
