Problems solved by technology

However, in the current comprehensive test process of single-device mode, it is very difficult to realize joint parallel testing of two devices. The main performance is that the design of the test system and test equipment is basically for a single spacecraft, especially for the entire satellite data flow. Processing, there is no effective system and method for processing downlink data in support of multi-device joint work

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] The invention provides a data processing method for joint testing of two devices, the involved equipment includes a patrol device, a lander and a total control console, wherein the total control console is respectively connected to the patrol device and the lander through an external interface, figure 1 A flow chart of the method is shown, and the specific steps of the method are:

[0023] S00. Receive and identify data.

[0024] The main console receives the lander data and the patrol data in real time respectively through the external interface. The lander data includes telemetry data or digital transmission data 1, and the patrol data includes bus data or digital transmission data 2. At the same time, data identification is carried out on the received data, specifically: add "CE1" before each frame of lander data received from the lander interfa...

Abstract

The invention discloses a data processing method used for a two-device joint test, and the data processing method can finish parallel processing of two-device downlink data to achieve the purpose of improving the data processing efficiency. The data processing method comprises the steps as follows: marking lander data and patroller data received by a main control platform respectively; identifying each data frame and adding a data type mark bit; carrying out queue caching on the lander data, patroller data downloaded through a lander interface and the patroller data respectively; carrying out data processing on all queues at the same time to obtain corresponding engineering value data stream; and storing the engineering value data stream into a database in a controller.

Description

technical field [0001] The invention belongs to the field of spacecraft testing, and in particular relates to a data processing method for joint testing of two vehicles. Background technique [0002] The spacecraft of the Chang'e Phase II project includes a lander and a probe. The ground test needs to simulate the joint work mode of the two devices. However, the current comprehensive test of spacecraft in my country is a decentralized manual operation mode, and the comprehensive test is mainly based on a single device. Although after years of hard work, and on the basis of learning from foreign test systems, the spacecraft comprehensive test system has been developed, which has changed the system structure of the traditional test decentralized model and formed a distributed system structure centered on the master control test equipment, which has also improved The level of automated testing in individual spacecraft testing has been improved. However, in the current comprehe...
