Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0031] Such as figure 1 Shown is a schematic diagram of the system structure of the present invention.
[0032] The entire automated test system is mainly composed of six parts, namely a fixed platform 101; a test product 104; a four-degree-of-freedom mechanical mechanism 105; a remote control system 106; a three-dimensional reconstruction subsystem 107; Both the single particle emission device 102 and the particle beam 103 are provided by the test environment.
[0033] Except that the remote control system 106 is installed in the control room, the rest are all installed on the 101-fixed platform.
[0034] The 3D reconstruction subsystem 107 is installed on the -Y side of the fixed platform 101 and looks up to the +Y direction. The video monitoring system 108 is installed on both sides of the single particle emission device 102, and the ang...

The invention relates to a single event effect automatic test system. A four-degree-of-freedom mechanical mechanism is connected with a remote control system, is used for placing a test target, and receives a motion control instruction of the remote control system; a single particle emission device is connected with the remote control system and receives a switching control instruction of the remote control system; a three-dimensional reconstruction subsystem is connected with the remote control system and receives the switching control instruction of the remote control system; and the remotecontrol system receives position information and type information of the test target fed back by the three-dimensional reconstruction subsystem. The scheme of the invention is applied to the technicalfield of space radiation effect simulation tests, innovatively adopts an automatic control operation mode, solves the problems of low efficiency and frequent manual operation in the traditional single event effect ground test, also provides a fully-automatic and unmanned operation mode, greatly improves the test efficiency, the measurement accuracy and the safety of testers, and simultaneously improves the utilization rate of test equipment and reduces the test cost.
Description
technical field [0001] The invention relates to the technical field of space radiation effect simulation test, in particular to a single event effect automatic test system. Background technique [0002] After the high-energy particles in the cosmic rays are injected into the semiconductor device, they deposit energy in its sensitive volume, causing the device to flip, lock, or even burn out, which is called the single event effect. There are many high-energy charged particles in the space environment. When various spacecraft such as satellites and space stations operate in space, they are often radiated by high-energy charged particles, resulting in single event effects. The single event effect has serious harm to the electronic system of the spacecraft, and it is one of the main causes of abnormalities and failures of the spacecraft, which affects the reliability and service life of various spacecraft. [0003] In addition, with the continuous improvement of the integratio...
