Abstract

System and method are utilized for testing the performance of a gas monitor against predetermined monitor characteristics to determine if performance of a gas monitor is validated following testing gas being directly delivered to a gas sensor of the gas monitor.

Claims

1. A system comprising:

a gas monitor assembly; and

a gas testing system;

the gas monitor assembly includes a gas sensor assembly and a data transmitting device for transmitting data regarding sensed testing gas readings of the gas sensor assembly;

the gas testing system being remote from the gas monitor assembly and includes a data receiving device, and a data processing system, the data processing system includes a testing module;

the data processing system is operable for receiving test data relating to sensed testing gas values, wherein the testing module is operable for determining performance of the gas sensor assembly based on the received test data.

2. The system of claim 1, wherein data transmitting device in the gas monitor assembly includes one or more contacts for transmitting data;

and wherein the gas testing system is portable and the data receiving device includes a connector assembly for physically coupling to the one or more contacts.

3. The system of claim 1, wherein the gas monitor assembly includes a wireless data transmitting device;

and wherein the gas testing system is portable and the data receiving device includes a wireless receiver.

4. The system of claim 1, wherein the wireless receiver device utilizes RF.

5. The system of claim 1, wherein the data processing system includes a digital processor, a memory coupled to the processor and operated on by the processor, and the testing module resides in the memory.

6. The system of claim 1, wherein the gas testing system is a portable computer system.

7. The system of claim 1, wherein the testing module allows an accelerated processing of the test data for determining if a passing condition of the gas sensor assembly has been reached with the gas sensor assembly being operated in a normal mode.

8. The system of claim 7, wherein the testing module obtains a first reading value of testing gas applied to the gas sensor assembly, stores the first reading value, obtains a second gas sensor assembly reading value, determines a rate-of-rise value of the first and second reading values based on a difference of the first and second reading values relative to a testing time interval therebetween, and, determines if a gas sensor assembly passing condition exists based on a comparison of the rate-of-rise value to at least a first predefined rate-of-rise value of the gas sensor assembly

9. The system of claim 8, wherein the testing module determines if the passing condition exists if the rate-of-rise value of the first and second reading values is greater than a second predefined rate-of-rise value of the gas sensor assembly.

10. The system of claim 1, further comprising:

a plurality of the gas monitor assemblies networked together, each one of which includes one of the data transmitting assemblies;

wherein the data receiving device is couplable to each of the data transmitting assemblies through a network.

11. A method for testing one or more gas monitors, each of which includes a gas sensor assembly and a data transmitting device for transmitting data regarding sensed testing gas reading values of the gas sensor assembly, the method comprising:

applying testing gas to the gas sensor assembly of one gas monitor, and determining performance of the gas sensor assembly by a testing module in a data processing system that is responsive to the data processing system receiving test data relating to sensed testing gas reading values.

12. The method of claim 11, wherein the testing module allows an accelerated processing of test data for determining if a passing condition of a gas sensor assembly has been reached with the gas sensor assembly being operated in a normal mode.

13.

14. The method of claim 13, wherein the testing module determines that the passing condition exists if the rate-of-rise value of the first and second reading values is greater than a second predefined rate-of-rise value of the gas sensor assembly.

15. A computer network comprising:

a plurality of gas monitor assemblies coupled in a network, each one of which includes a gas sensor assembly, and a data transmitting device that transmits test data representative of performance of a gas sensor assembly to testing gas of each of a gas monitor assemblies; and

a data processing system in the network, the data processing system includes a testing module;
