How the SenSource Sensor Server Works
- Wi-Fi and IP sensors
Wi-Fi and IP sensors transmit their count values to a single sensor server located at the corporate data collection center using a network router. *The above diagram depicts a Wi-Fi/IP scenario.
418 MHz and 900 MHz sensors
Wireless sensors transmit their count values using a 418MHz or 900MHz radio transmission to a sensor server located within each facility. - Using Vea Software, data is stored and collected onto a MS SQL database using either a PC or server.
- Distributed installations of Vea can be used to configure, collect, monitor and report on traffic data.
Overview of Operation
Sensor Communication
Sensors transmit their count values and operating status at predetermined intervals to the sensor server through a simple RS485 serial connection or a proprietary 400MHz or 900MHz wireless signal. The wireless signal is strictly for data communication from the sensors to the sensor server and is not compatible with any networking protocols such as 802.11 standards in order to prevent any security concerns.
Data Logging on the Sensor Server
The sensor server receives the latest count value and operating status from each sensor then stores it in a temporary memory location. The sensor server will store event occurrences predefined by the user such as communication problems, counter status or configuration changes. The historical log remains on the sensor server until it is full (15,000 records) at which time the sensor server will begin purging the oldest record as each new record is stored. Approximately 208 days of historical days with one hour logging intervals from one sensor can be stored on each sensor.
Pushing Data from the Sensor Server
The sensor server can push data in XML format to a Web Server or an XML Server. This utility is installed on a PC or server and runs in the background controlling the flow of XML data from all sensor servers. In this configuration, each sensor server pushes new data to the specified URL path at predetermined time intervals.
Data Content
Each line of data contains the following information: server ID, sensor ID, differential count value IN, differential count value OUT, time, date, sensor state and sensor type.
Reporting
Vea Software completes the people counting system by providing powerful reporting and monitoring tools. Reports can be generated with "one click" or automatically emailed to designated recipients. Vea Software will also allow monitoring of valuable performance metrics in near real-time as well as generate instant notification when parameters exceed maximum or minimum limits. POS and/or other existing data can be easily integrated with SenSource data. Automatic calculations on combined data provide an exceptional reporting solution. Vea Software can also log historical information regarding sensor or performance exceptions and corrective actions.
