Abstract
In large systems of ambient condition detectors the respective detectors can each include an RFID-type tag or integrated circuit. The tag can transmit detector identification information and status information wirelessly to a displaced receiver. Receivers can be installed in docking/test stations as well as in portable units which can be carried by an individual entering, or, moving through a region being monitored by the detectors.
Description
System and Method of Determining Gas Detector
Information and Status via RFID Tags
FIELD
[0001] The invention pertains to systems that need large numbers of gas or smoke detectors to monitor an industrial or commercial environment. More particularly, the invention pertains to detecting the status of such detectors in the context of managing large industrial environments such as refineries.
BACKGROUND
[0002] Large numbers of gas detectors are frequently required during events such a refinery shutdowns and there are several companies that provide rental instruments as a service. In the event of large refinery shutdowns, several thousand rental gas detectors may be required. In these situations, both the rental company and the company using the detectors have to manage a large number of instruments. They must determine ownership of instruments as well as verify the operational status of each instrument.
[0003] While every instrument has a unique serial number, it can be difficult to read and the operational status of the instrument (i.e. is the calibration and bump check status up to date). It is desirable to have some means of quickly and reliably reading large numbers of instrument serial numbers as well as the associated operational status. It is also desirable to collect this information without having to remove detectors from packaging or shipping containers.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] Fig. 1 is a block diagram of an RFID enabled system which embodies the invention;
[0005] Fig. 2 is a block diagram of an RFID related subsystem of Fig. 1 ; and
[0006] Fig. 3 is another block diagram of an RFID enabled detector in accordance with invention.
DETAILED DESCRIPTION
[0007] While embodiments of this invention can take many different forms, specific embodiments thereof are shown in the drawings and will be described herein in detail with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention, as well as the best mode of practicing same, and is not intended to limit the invention to the specific embodiment illustrated.
[0008] Embodiments of the invention can include adding an RFID tag chip to at least some of the detectors. RFID tag chips contain pre-programmed information and when interrogated by an RFID reader, they respond. RFID tags do not need external power and will respond even when the instrument is switched off or inactive.
[0009] The RFID tag can be programmed with the instrument serial number, model number and sensor configuration by the manufacturer. This information will be permanently stored in the RFID tag and will allow anyone with an RFID reader to query the instrument. This will allow easy asset tracking for the detectors.
[0010] In an aspect of the invention, the RFID tag can transmit the current status of the detector. This adds significant value because it allows users to easily determine the status of instruments even if they are in cartons or other containers. The current status of the instrument can be encoded into the RFID tag in different ways.
[0011] In a disclosed embodiment, an RFID tag with an external interface can be incorporated into the circuitry of a detector. One such RFID tag is commercially available as an Atmel ATA5570 RFID IC. This device has an external sensor input that allows the IC to indicate whether an external resistance is high or low when queried. The detector circuit can be constructed such that the external resistance is high when the detector is operating properly (all self-tests passed, sensors within calibration interval and within bump check range) and low when the detector is out of conformance with pre-determined parameters and in need of maintenance.
[0012] Alternately, RFID tags with digital interfaces are available
commercially. These interfaces allow considerably more information to be transferred from a programmable processor, or microcontroller in the gas detector to the RFID tag. Examples of these chips include, without limitation, Texas
Instruments TMS37157, ST Microelectronics M24KR64, a Melexis ML90129 and a
Ramtron WM72016. The information transferred from the gas detector's
microcontroller to the RFID chip through this interface can include gas detector status, last calibration date, gas type, etc. Such additional information can be used by a displaced, or, an external monitoring system as would be understood by those of skill in the art.
[0013] In another embodiment, a docking/test station can be equipped with an RFID reader/writer. When an instrument is bump tested or calibrated, the docking/test station can use the RFID reader/writer to update the information in the RFID tag on the associated detector. The RFID tag on the detector could then retain the most recent dates for bump testing and calibration operations.
[0014] In either of the above embodiments handheld RFID readers could query the detectors for the stored information at any time.
[0015] In mustering applications, RFID tags in detectors duplicate the function of security tags in use. In this embodiment, users can scan in at a mustering point with their detector instead of an id badge.
[0016] In access control related applications, a gas detector can be used to control entry to restricted areas. For example, the gas detector must be of the correct type and in working condition (bump check valid, etc.) in order to gain entry to an area.
[0017] In inventory management related applications, a box of detectors can be scanned with an RFID reader. The detectors could then be signed in or out of a facility as a group. This aspect can be used to manage large numbers of detectors in rental fleets, manufacturing, distribution, etc.
[0018] In yet another aspect of the invention, detector status can be checked via an RFID reader at facility entry points. If a detector is compliant with policy (correct gas type, bump check & calibration interval correct, self-tests passed, etc.) then the user can enter facility. Readers can be installed at facility gates and/or operations offices. This process can also be implemented in the facility using a hand held RFID reader. This is useful for performing spot checks.
[0019] Further, the status of one or more detectors can be checked at exit points to see if an alarm/event occurred during the user's shift. If an alarm was reported, the user can complete an incident report either on paper or on-line. A hand held computer with an RFID reader can be used to enter incident reports on the spot reducing time for incident reporting.
[0020] Embodiments of the invention support loss prevention programs. For example, RFID reader gates can be set up at facility entry/exit points. Detectors passing through these points can then be recognized and a signal is generated which indicates that presence of a -detector has been recognized. Thus, detectors can be signed out and/or returned to the facility.
[0021] Preferably, onboard RFID tags in respective devices can be
programmed with user information such as operator name and/or Operator ID.
[0022] Fig. 1 illustrates a system 10 in accordance with the invention. The system 10 can include a plurality of RFID-type enabled detectors 12, 12-1 , 12- 2...12-n, of which detector 12 is an example. The detectors, such as 12 are in wireless communication, intermittently, with an RFID reader 14 which is in turn coupled to a gas detector data management system 16. System 16 can be implemented with one or more personal computers, such as 16-1 which execute data management and collection software 16-2.
[0023] The components of detector 12, and the other members of the plurality 12-1 ...12-n can be carried in a respective portable housing such as 12a. A clip 12b, of a type that can be used to attach the detector 12 to clothing or equipment of a user, is affixed to the housing 12a. The detector 12 can be energized by an internal, replaceable battery B.
[0024] As will be understood by those of skill in the art, the detectors, such as detector 12 can include a gas sensor 20a which is in turn coupled to interface circuitry 20b. The interface circuitry 20b can in turn be coupled to a programmable processor 20c. The processor 20c can include or be cou pled to storage unit(s) 20d such as EEPREOM or ROM storage devices which can store control software executable by the processor 20c.
[0025] An RFID subsystem, interface, 22 is carried by housing 12a and coupled to the sensor/control circuits 20. Interface 22 is in wireless communication with the RFID reader 14.
[0026] As illustrated in Fig. 2, the RFID subsystem 22 includes an RFID chip 32. The RFID chip 22 includes some nonvolatile memory which is used to store gas detector information. The information stored in the RFID chip 22 can include, without limitation:
• Detector model number
• Detector serial number
• Gas type of detector
• Operator name
• Last calibration date
• Last bump test date
• Last alarm date
• Power up self test status (pass or fail)
• Current status information (pass or fail)
[0027] The above representative information can be obtained from the gas detection circuitry 20 and can be written to the RFID chip 32 by the gas detector microcontroller 20c. The over the air RF link can be used to read data from the RFID chip 32.
[0028] As those of skill will understand, all of the information listed above can be stored in the EEPROM 20d on the RFID chip 32 prior to interrogation by an RFID reader 14. The Status information can change suddenly (if the battery is removed for example) and the processor 20c may not have the opportunity or ability to update the status in the RFID chip's EEPROM 20d. In this case, the RFID chip 32 can initiate a read of the status information from the gas detector processor, or microcontroller, 20c over a digital link 32a when an RFID reader 14 interrogates the RFID chip 32.
[0029] Alternately, if the RFID chip 32 has a sensor input 32b it can be used to indicate status information over the RF link. Some RFID chips have a sensor input where an analog voltage can be read. A digital output 32c on the gas detector microcontroller 20c can be connected to the RFID 32 chip as illustrated in Fig. 3.
[0030] For example, if the microcontroller 20c is off, or the microcontroller pulls the status line 32c low to indicate an off state, then the RFID chip 32 will read a low voltage at the sensor input pin 32b. This will in turn be reported back to the RFID reader 14 when the RFID chip 32 is queried. Similarly, when the
microcontroller 20c pulls the status line 32c high the RFID chip 32 reads a high voltage at the sensor input pin 32b and status indicator is reported as being active.
[0031] From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
