Rail Transit Signaling System Supporting Secondary Software Development

Abstract

The invention also provides a rail traffic signal system supporting secondary software development. The system includes: external equipment, and a safe computer platform, and the safe computer platform further includes: a safe platform host, and the safe platform host includes application software for the external equipment developed by end users; and a communication plug-in, the communication socket includes a communication interface, the external device communicates with the communication plug-in through the communication interface, wherein the communication plug-in sends the data received from the external device to the security platform host, and forwards the data sent by the security platform host to the external device to the external The device, wherein the communication plug-in integrates the underlying driver for the communication interface and provides a secondary software development interface, so that end users can use the secondary software development interface to develop the application software.

Description

technical field [0001] The invention relates to a rail transit signal system, more specifically, to a secondary software development interface and method for a safe computer platform in the rail transit signal system. Background technique [0002] With the continuous advancement of technology and the increasing requirements of rail transit systems for safety, reliability and automation, signaling systems, as the core field of rail transit systems, have become more and more important, and their technical complexity is also increasing . As for the on-board control equipment and ground equipment of the rail transit signaling system, whether it is an urban rail transit signaling system or an arterial railway signaling system, whether it is a CTCS1 or CTCS2 train control equipment or a CTCS3 or CTCS4 train control system, there is a common The core key technology is the railway signal safety computer technology. This core technology is currently the weakest part in the domestic...

AI Technical Summary

Problems solved by technology

[0006] The existing rail transit signal system security platform provides end users with application software development methods, which have high development costs and long development time. For example, in-depth customization and development of application software based on the security platform, the specific operation method is that the end user submits the application requirements For the security platform R&D team, the security platform R&D team will develop application software according to specific user needs

Due to many factors such as unfamiliarity with the application business or unclear description of the end user, the custom-developed application software will require more time overhead (other costs will also increase accordingly)
