Wireless communication transportation signal control device and control method

Abstract

The invention provides a wireless communication transportation signal control device and control method. The wireless communication transportation signal control device comprises six function modulesof a wireless intelligent transportation signal dispatching unit, a wireless/wired flow acquisition unit, a wireless light control and output unit, an Enocean communication unit, an anomaly monitoringunit and a wireless fault alarming unit; modularized design is adopted by the device, and the modules support hot plugging. A set of wireless intelligent communication transportation signal control device which is safe, convenient to install and user-friendly in operation is provided for a client. The device is stable and reliable, a novel Enocean wireless communication technology is adopted, andthe device is efficient, saves energy and protects the environment. The device supports a remote wireless control intersection communication signal state and a local wireless control intersection communication signal state and saves the energy and capital for the transportation management department. A feasible solution means is particularly provided in the aspect of remote maintenance, it is guaranteed that a manager finds a system fault in the first time, and a whole set of solution scheme is provided for system stable running.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control. Background technique [0002] With the continuous development of the city and the increasingly severe urban traffic conditions, the signal control system needs to implement a multi-phase control method, which inevitably requires the corresponding transformation of the signal control system. However, there are currently some difficult situations. First, it is difficult to implement the reconstruction of the underground pipe network in the old urban area, and it is extremely difficult to add cables; second, the cost of cables continues to increase. If the intersection signal lights use cables to transmit AC220V, the cost will increase sharply; and there is a power carrier method. Due to the clutter interference of the power grid, isolation equipment needs to be added; the wireless signal control device based on GPS clock synchronization lacks state feedback between devices, and needs to b...

Problems solved by technology

This patent is mainly designed for countdown real-time control and multi-intersection control. This patent does not consider the reliability of the communication subsystem involved in the system. How to deal with communication abnormalities of one or several wireless modules is not considered in the patent at all; there is no consideration in the patent. Design fault degradation function; the traffic signal intersection using wireless communication method first considers solar power supply, and this invention does not involve solar charge and discharge management and energy saving. As the distance increases, the required capacity of wireless transmission increases sharply. None of the previous products in the field of signal wireless control involved high efficiency and energy saving
