Abstract

The invention provides an FPGA development module based traffic signal control demonstration box. The demonstration box has an embedded signal machine system. The signal machine system is adopted by adopting an ARM, so that external software interfaces can be simplified. The compiling environment is an embedded Linux system established based on the ARM. Interfaces of an FPGA end are controlled through bottom layer drive. Chip transfer is realized through external serial-parallel connection and transfer connection to signal lights, a detector and a digital tube interface is achieved. Different timing demands can be met through programming by a user. The invention is not only a demonstration tool of a signal machine. Besides, hardware complexity is reduced greatly and power consumption is reduced, so that cost is saved.

Description

technical field

[0001] The invention belongs to the technical field of the combination of intelligent traffic control and management, and relates to an experimental teaching device of a programmable multi-semaphore control timing scheme, which is used for the teaching of traffic engineering-related courses and demonstrates the working principle of the signal machine for students , on this basis, students can simulate the timing control scheme of signal lights under various requirements through programming. Background technique

[0002] With the development of urban transportation, many enterprises and universities have invested in the R&D and experimentation of traffic signal control equipment, but the previous experimental device was only a simple display tool externally loaded on the signal machine, and users could neither test the experimental box on site. Perform programming control, replace the timing scheme, and there are problems such as huge volume, single simulation...
