Abstract

A portable subsystem carried by the inspector includes an identification scanner, an emissions sensor and a portable data collector. An inspector identifies the release point by use of a portable scanner and then tests the release point for leaks. The portable data collector stores the identification along with the emissions test data. At periodic intervals the portable data collector is connected to a main computer and the stored data is uploaded. The main computer analyzes the uploaded data for a pass or fail of the release point of the emissions test and issues the appropriate comparison results. Additionally, the severity of the leak is determined and remedial action is specified. This remedial action includes issuance of a repair report and updating the repair schedule, updating the inspection schedule for reinspection after repairs are completed and updating the inspection history. The computer is capable of generating reports tailored to the requirements of government agencies.

Claims

1. An apparatus for monitoring emissions from an emissions release point, comprising:

a machine-readable identification code disposed at the point;

a portable code reader which reads the identification code and provides an identification signal representative thereof;

a portable sensor which senses the emissions from the release point and provides a sense signal representative of those sensed emissions;

a portable data collector coupled to the code reader and to the sensor which directly receives the identification signal and the sense signal and records the identification and sense signals as data; and

a main computer which receives the recorded data and compares the sense data to a predetermined threshold and reports the result of the comparison.

2. The apparatus of claim 1 wherein the identification code is carried on a bar code label attached at the item and the portable sensor comprises a bar code scanner.

3. The apparatus of claim 1 wherein the portable scanner comprises a laser bar code scanner.

4. The apparatus of claim 1 wherein the main computer further issues a repair report when the sense signal data exceeds the threshold.

5. The apparatus of claim 1 wherein the main computer generates a history of the release point comprising each date that the portable sensor sensed the characteristic and the results of each comparison and updates that history for each comparison.

6. The apparatus of claim 1 wherein the portable data collector also records the date and time when it records the identification and sense signals, and the main computer receives the date and time and updates the history of the item.

7. The apparatus of claim 1 wherein the portable data collector opens a record upon receiving a first identification signal of the release point, records the identification signal and the sense signal as data and closes and stores the record upon receipt of a second identification signal;

and

the main computer receives the record, stores the record, and compares the sense data of the record to the predetermined threshold.

8. The apparatus of claim 7 wherein the first identification signal must receive the second id signal within a predetermined time after receiving the first id signal or no record formed.

9. The apparatus of claim 1 wherein the identification code is unique to the emissions release point.

10. A method for monitoring emissions from an emissions release point comprising the steps of:

applying a machine-readable identification code to the release point;

reading the identification code with a portable code reading apparatus and providing an identification signal representative of the code read;

sensing the emissions from the release point with a portable emissions sensor and providing an emissions signal representative of the sensed emissions;

directly receiving the identification signal and the emissions signal with a portable data collector and recording the signals as data;

transferring the recorded identification and emissions data to a main computer;

comparing the sensed emissions data to a predetermined limit in the main computer and reporting the result of the comparison; and

storing the result of the comparison and the identification data.

11. The method of claim 10 wherein:

the step of applying an identification code comprises applying a bar code at the location of the release point; and

the step of reading the identification code comprises scanning the bar code.

12. The method of claim 10 wherein the step of scanning comprises scanning the bar code with a portable laser scanning apparatus.

13. The method of claim 10 wherein the steps of reading the identification code, sensing and recording data comprise the steps in the following order:

reading the identification code with the code reading apparatus;

recording the identification code as data in the portable data collector;

reading the identification code a second time; and

recording the identification code a second time.

14. The method of claim 10 further comprising the step of issuing a repair report when the sensed emissions data exceeds the predetermined limit.
