Abstract

An environment monitoring system and method for systematically and continuously monitoring an environment. The system and method includes a data acquisition system which is programmed to systematically collect environment data for a site. The data acquisition system includes sensors coupled to a data storage device having a remote access device for electronic access from a remote system. Data may be uploaded to a remote database for storing environment data from many sites. The remote database includes a remote access device so that the data storage devices of various data acquisition sites can be electronically coupled to the remote database for centralized data collection and storage.

Claims

1. An air quality monitoring system comprising:

a data acquisition system for collecting air quality data at a data acquisition site, said data acquisition system including;

at least one sensor for measuring air quality data;

a data storage device coupled to the sensor for storing data measured by the sensor;

a remote access device coupled to the data storage device for electronically accessing measured data stored on the data storage device from a remote system;

means for converting sensor data to an air quality measurement based upon sensor type;

a remote database for storing air quality data from a plurality of data acquisition systems;

a remote access device coupled to the remote database for electronically accessing the remote database for uploading and storing measured data from data acquisition sites; and

means for systematically and automatically uploading data from acquisition sites to the remote database.

2. The air quality monitoring system of claim 1 including a plurality of sensors at a data acquisition site, said plurality of sensors being coupled to the data storage device.

3. The air quality monitoring system of claim 2 wherein the sensors are fixedly installed at distributed locations at a site and coupled to the data storage device.

4. The air quality monitoring system of claim 3 wherein the sensors output a voltage signal proportional to the measured air quality and a voltage to current converter is included to convert the voltage to current to transmit the measurement to a processing device for storage by a data storage device.

5. The air quality monitoring system of claim 4 wherein the remote database includes a system for converting the voltage to an air quality measurement.

6. The air quality monitoring system of claim 2 and including a site controller coupled to the sensors and programmed to systematically initiate collection of environment data at defined intervals from the sensors and storing said data to the data storage device.

7. The air quality monitoring system of claim 2 including a plurality of sensors which measure different air quality attributes coupled to a data storage device and means for converting the measurements to air quality data based upon the sensor type of the measured data.

8. The air quality monitoring system of claim 1 wherein the sensor includes an ionizing particle sensor device.

9. The air quality monitoring system of claim 1 wherein the sensor includes a volatile organic compound (VOC) sensor.

10. The air quality monitoring system of claim 1 wherein the air quality data is stored via a site identification number on the remote database.

11. The air quality monitoring system of claim 1 wherein the remote database is coupled to a printer for generating reports of the air quality data.

12. The air quality monitoring system of claim 1 wherein the remote database is coupled to a distributed wide area network for remote access to the database.

13. The air quality monitoring system of claim 12 wherein the environment data is stored by site and is accessible through the distributed wide area network by password codes.

14. The air quality monitoring system of claim 1 wherein the site controller is programmed to initiate remote electronic communications with the remote database to upload data.

15. The air quality monitoring system of claim 1 wherein the remote database includes a controller programmed to initiate remote electronic communications with the data storage devices of various sites for uploading data from the various sites to the remote database.
