Embodiment 1

[0055] Such as Figure 1 to Figure 4 As shown, the present invention discloses a method for monitoring the status of a launch vehicle, which is implemented by five threads. The five threads include a main process, a data receiving process, a data storage process, a data refresh process, and a timer process. Used to display status data and analysis results, the data receiving process is used to obtain data from the CAN bus, the data storage process is used to store the obtained data, the data refresh process is used to update the data displayed on each monitoring interface, and the timer process Used to control the operating cycle of each process.

[0056] Specifically, the monitoring method of the launch vehicle turntable of the present invention includes the following steps:

[0057] Step 1. Before starting the data receiving thread, the monitoring method includes the step of starting the timer thread. The timer thread is used to set the running period of the data receiving thread...

Embodiment 2

[0071] Such as Figure 2 to Figure 4 As shown, corresponding to the aforementioned method for monitoring the state of the launch vehicle, the present invention also discloses a monitoring device for the state of the launch vehicle. The monitoring device includes a data acquisition module, a data upload module, a data display module, a data storage module, and a data analysis. Module and cycle setting module. Such as Figure 4 As shown, the device for monitoring the status of the launch vehicle of the present invention can be integrated in a status detector, which is connected to the first CAN bus and the second CAN bus, and the acquisition box monitors the status of each node on the two CAN buses; , The vehicle control unit, motor control unit, main control unit, main valve box control unit, gateway unit and acquisition unit are the control units on the vehicle control system of the launch vehicle. The main control unit is used to control other control units. The control unit ...

Abstract

The invention discloses a monitoring method of emission vehicle states and a device. The monitoring method comprises following steps of step 1, starting a data receiving thread, and acquiring state data of each node from a CAN bus by use of the data receiving thread; step 2, uploading the state data into a data receiving queue; and step 3, starting a data refresh thread, uploading state data in the data receiving queue to an already started main thread by use of the data refresh thread and displaying the state data on an interface by use of the main thread. A monitoring device comprises a data acquisition module, a data uploading module, a data display module, a data storage module and a data analysis module. According to the invention, a cross-platform comprehensive state monitoring method based on JAVA multi-threads is provided, so various and complex state monitoring requirements of emission vehicles are met, a function of multi-state monitoring is achieved and an expected effect is achieved.

Description

Technical field [0001] The present invention relates to the technical field of launch vehicles, and more specifically, the present invention is a method and device for monitoring the state of launch vehicles. Background technique [0002] As the functions of the rocket launch vehicle become more abundant and perfect, the requirements for the state monitoring of the launch vehicle have also become diversified and complicated. It is often necessary to implement various monitoring functions of the launch vehicle state. Therefore, the state monitoring of the launch vehicle The system platform requirements are getting higher and higher. However, due to technical limitations, the simultaneous implementation of multiple monitoring will take up a lot of computing overhead for the processor, and the update speed of the interface cannot meet the actual needs. Therefore, the traditional launch vehicle status monitoring system can only achieve a single and simple status monitoring; and It c...
