Central control system of intelligent electronic station board

Abstract

The invention discloses a central control system of an intelligent electronic station board. The central control system comprises a central control device which is composed of a power supply part, an RK3288 and MCU part, five sets of direct current control, a vibration switch, a smoke sensor, two sets of 232 modules, three sets of 485 modules, ten sets of IO input, two sets of alternating current control, current detection and zero-cross detection. The RK3288 and MCU part comprises a processor RK3288, a memory, a 4G module, a network part and an STM32F4 series MCU; the circuit of the vibration switch comprises a vibration switch and an LM393 comparator circuit; the smoke sensor adopts a plane smoke gas sensor and a comparator to build a smoke detection circuit; the 10 groups of IO inputs can be externally connected with various sensors. The intelligent electronic station board has a fault self-detection function, a glass breakage detection function and a smoke detection function, and the intelligent degree of the electronic stop board is improved.

Description

technical field [0001] The invention relates to the technical field of electronic stop signs, in particular to a central control system of intelligent electronic stop signs. Background technique [0002] The Guiding Opinions on Prioritizing the Development of Public Transport in Cities pointed out: "In recent years, my country's urban public transport has developed rapidly, the level of technical equipment has been continuously improved, the achievements in infrastructure construction and operation have been remarkable, and people's travel has become more convenient. However, with the accelerated development of my country's urbanization , the development of urban transportation is facing new challenges. Urban public transportation has the advantages of intensive, efficient, energy-saving and environmental protection. Prioritizing the development of public transportation is an inevitable necessity to alleviate traffic congestion, change the mode of urban transportation developm...

Problems solved by technology

[0005] The existing electronic station sign centralized control equipment communicates with the Android industrial computer through the network port, and needs to add a router device. The gateway and IP of the centralized control device need to be configured for communication through the network port, and the IP of the Android industrial computer needs to be fixed. Obtained randomly, the on-site configuration personnel often fail to upload the stop sign data due to improper configuration, greatly increasing the debugging time, and the on-site personnel complained

And the current electronic station sign centralized control equipment does not have smoke detection and glass breakage detection functions
