This product belongs to the core signal control equipment of the rail transit industry. It is used for rear-end collision protection of subway trains under emergency operation (manual driving) conditions. It can greatly improve driving safety, avoid large-area congestion, and have significant social benefits. This product focuses on the market gap where urban subway trains lack safety protection equipment during emergency operation, and has huge development potential. According to the current plan, by 2020, there will be more than 10,000 subway trains allocated nationwide, with an estimated budget of 500,000 yuan for each train and an investment of more than 5 billion yuan. With the purchase of additional trains and follow-up accessories, the domestic market capacity will be more than 10 billion yuan.

In the early stage, it was funded by the Shanghai City Science and Technology Commission, and the expert acceptance evaluation was "the first in China, and the product performance reached the international leading level." In 2015, it was again funded by the Municipal Science and Technology Commission to complete optimization and upgrade based on domestic processors and independent operating systems. Currently, it has obtained 1 authorized invention patent, 1 software copyright, 1 entrusted test report from Shanghai City Quality Supervision and Inspection Technology Research Institute, and 1 test report from China Railway Communication and Signal Shanghai Telecom Test Center. Prototypes have been available and have been tested in small batches, including Shanghai Line 11 3 trains and Line 7 Quanyan 42 trains, whose technological and intellectual maturity has reached the pilot stage.
