Challenge

Traditional traffic data acquisition device normal consists of two parts: the sensor and the controller. The controller links with the central management though wired connection and sends back the data collected the sensor. However, installation of the wire-line relates to huge engineering efforts and the maintenance of fixed lines has always been difficult. There will be more problems to get wired connection in remote areas.

Solution

In Helicomm's application, MA8 devices are used to link with the traffic data acquisition devices through RS485 interface. The raw data from the detector is transmitted to the central traffic control center through GPRS network and Internet in TCP/IP packet. Data can be temporarily stored in the memory buffer when GPRS is disconnected. Only simple application is required at the central to access the terminal data, the system implementation can be accomplished within 3 weeks.
