Abstract

Systems and methods for remotely testing the operational status of a remediation system installed within a building or structure are disclosed. An illustrative remote monitoring system can include a sensor adapted to sense at least one characteristic of the remediation system, an interface in communication with the sensor, a gateway in communication with the interface, and a remote computer located away from the building or structure. The interface can be configured to convert sensor signals received from the sensor into an output signal having a format or platform supported by the gateway. The remote computer can include an interface that can be used by a servicing agent to transmit and receive signals to and from the gateway for monitoring and testing the operation of the remediation system.

Claims

1. A remote monitoring system for remotely testing at least one remediation system installed within a building or structure, each remediation system including a ventilation fan and an exhaust conduit, the remote monitoring system comprising:

a sensor adapted to sense the presence of airflow within the exhaust conduit;

an interface in communication with the sensor and a switch for switching the ventilation fan between an on and off position, the interface adapted to convert sensor signals received from the sensor into an output signal; and

a gateway in communication with the interface, the gateway adapted to transmit said output signal to a remote computer located away from the building or structure;

wherein the remote computer is configured to send one or more test signals to actuate the ventilation fan between said on and off positions and is further configured to analyze the output signals received from the sensor during each of the on and off positions.

2. A method of remotely testing at least one remediation system installed within a building or structure, each remediation system including a ventilation fan or pump, an exhaust conduit in communication with the ventilation fan or pump, and at least one sensor adapted to sense the presence of fluid flow within the exhaust conduit, the method comprising the steps of:

shutting down the ventilation fan or pump for a period of time;

sensing the presence of fluid flow through the exhaust conduit during the period of time that the ventilation fan or pump has been shut-down; and

transmitting a first test report back to a remote computer located away from the building or structure.

3. The method of claim 2, further comprising the step of providing a gateway and an interface in communication with the ventilation fan or pump and the at least one sensor, the interface adapted to convert sensor signals received from the sensor into output signals having a format or platform supported by the gateway.

4. The method of claim 3, wherein said step of shutting down the ventilation fan or pump is accomplished automatically via a self-test mode of the gateway unit.

5. The method of claim 2, wherein said step of sensing the presence of fluid flow through the exhaust conduit is accomplished using a pressure or flow sensor.

6. The method of claim 2, wherein said step of causing the ventilation fan or pump to shut-down is accomplished via a relay switch connected to the ventilation fan or pump.

7. The method of claim 2, further comprising the steps of:

transmitting a test signal to the ventilation fan or pump causing the fan or pump to turn-on; and

measuring the response time required to bring the remediation system back to a fully operational or equilibrium state.

8. The method of claim 2, further comprising the step of analyzing the first test report and dispatching a servicing agent to the building or structure if maintenance is required.

9. The method of claim 2 further comprising the steps of:

activating the ventilation fan or pump;

after the ventilation fan or pump has been activated, sensing the fluid flow through the exhaust conduit; and

transmitting a second test report back to a remote computer.

10. The method of claim 9 wherein the first test report and the second test report are transmitted separately.

11. The method of claim 10 wherein the first test report and the second test report are transmitted together.

12. The method of claim 10 wherein the first test report and the second test report are a common test report.

13. The method of claim 9 further comprising:

entering a self-test mode, wherein the self-test mode automatically performs the shutting down step, the sensing the presence of fluid flow through the exhaust conduit step;

the transmitting the first test report step, the activating the ventilation fan or pump step, the sensing the fluid flow through the exhaust conduit after the ventilation fan or pump has been activated step; and

the transmitting the second test report step.

14. The method of claim 13 further comprising:

automatically entering the self-test mode on a periodic or intermittent basis.
