Transportation application
In densely populated and traffic congested metropolitan areas, time is often delayed due to traffic congestion. Effective traffic control is very important. Among them, the signal control system and vehicle detector provide safe, automatic, and real-time traffic signal control and traffic flow detection, which can safely and effectively guide the traffic flow and ensure the smooth flow of vehicles. The road traffic data collection system is an important part of traffic control. In order to implement the basic equipment required for road traffic management, all traffic management strategies must rely on the information of the data collection system to formulate and execute traffic management strategies. In addition to the function of providing real-time data, the data collection system also provides historical data collected over a long period of time to provide traffic planning units as the basic information for drafting traffic control and planning.
The Challenge
The management of existing signal controllers is mainly based on dedicated line connections. The management of newly added signal controllers will require excavation and wiring works unless the wiring and installation are completed at the beginning of planning. Most of the problems encountered by existing management units are the disconnection of dedicated lines. Most of the reasons are caused by road excavation or stagnant water and other factors. However, these factors need to be repaired by related institutions. When things happen in a hurry, it is often necessary to control the lights with the help of manpower. If you need to implement the wireless method, because the general signal controller is mostly a dedicated system, and the system does not have a built-in wireless driver, the investment required to complete the design of AT Command or TCP/IP for GSM/GPRS connection is very huge.
A general vehicle detector includes two parts: a sensor and a terminal controller. The terminal controller is the sensor that interfaces with the front-end, which calculates and processes the vehicle data, and communicates with the central controller of the control center. The collected detection data are sent back to the data collection and processing facilities of the control center in real time or at regular intervals. The communication adopts the data dedicated line for transmission. However, the erection of the data dedicated line requires road excavation, which cannot be erected in more remote areas, causing difficulties in the installation. When the dedicated line is disconnected, the data is also lost, an expensive data collector is required, and a huge development is required when the system is built.
The Solution
The MA8 is directly connected to the traffic signal controller and detection device through the RS-232 interface. In the traffic signal controller, it can be connected without changing the existing settings and writing related procedures. MA8 provides built-in graphics The interface can be set to transmit data in accordance with the traffic signal communication protocol and data grid. It can also be filtered according to the conditions required by the competent authority to filter out some unnecessary information. The data can be transmitted back through the GPRS system and the Internet. Traffic control center. The Gateway can also be used to complete the integration with existing traffic control center equipment, saving communication equipment and a large amount of wires, management and maintenance are also relatively easy, system construction is fast and cost-saving, which is the best solution for various system integrators.
In terms of the detection device reading the data collected on site, the system can not only reduce the trouble of excavation and installation, but also quickly establish the detection station, use the protocol analysis method, and combine with the traffic detection system to send a large amount of data. The data analyzed into a pen data will be transmitted to the traffic management center via the GPRS network and the Internet. In addition to transmitting vehicle detection data, this case also uses MA8’s Digital I/O to detect the uninterruptible power system, which can inform the management center of the on-site power supply status. The traffic management center combines information obtained by other systems to formulate and evaluate traffic control strategies, and transmit relevant information to passers-by to achieve the goals of maximizing transportation efficiency and improving transportation safety.
