## Title
Connection line protection system

## Abstract

A connection line protection system employs unique identifiers on outlets and inlets. A connector connects a selected outlet with a selected inlet. The connector mounts at opposing ends an identifier that identifies the connector. A scanner is employed to scan in tandem a first identifier of the outlet and a connector identifier and a second identifier of the inlets and the identifier of the connector. The readings are compared with a schedule to determine whether the connector is properly mounted and connected between a selected outlet and a selected inlet. The identifiers include RFIDs and barcodes. The identifiers are preferably angularly spaced around the outlets, inlets and the couplers of the connector. The identifier may be affixed by snap rings mounting barcode labels or RFID buttons.

## Background
BACKGROUND
In the liquid distribution industry, such as bottling and canning operations and liquid fuel deliveries, such as oil and gasoline, it is necessary to use temporary hose connections between the tanks storing the liquid and bottling equipment or tanks receiving the liquid. It is possible, if the operator is not careful, to introduce the wrong liquid into the wrong production line or storage tank because multiple hoses can be used simultaneously in large bottling facilities and multiple tanks used on delivery trucks and multiple tanks can be used to store the liquid at the sites. This mix-up could be quite costly and time-consuming to correct the error.
To prevent the mix-up between hoses, tanks, and bottling and canning equipment, it is highly desirable to have an automatic identification system, that will quickly and accurately verify that the interconnect hoses are connected to the correct ports. This disclosure partially pertains to techniques of identifying the hose connections and the ports to which they are attached to. It is very important that the identification is easily achieved, accurate, and cost-effective. Two different methods of identification are employed. The first uses the barcode technology and the second uses RFID technology. Both systems use a portable scanner, with wireless communications back to a central processor that either verifies the hose connections are correct or alerts the operator if there is an incorrect connection.
SUMMARY
Briefly stated, the connection line protection system comprises a first array of outlets that each have a first unique identifier and a second array of inlets that each have a second unique identifier. The connection line protection system also comprises a connector having opposed ends that each have a connector identifier and a scanner for reading in tandem a first identifier and a connector identifier and a second identifier and a connector identifier. The scanner compares the readings with a schedule to determine whether the opposed ends of the connector are properly connected between an outlet and an inlet. The identifiers comprise barcodes or RFIDs. The first array of outlets may be manifold ports and the second array of inlets may be inlet ports. The manifold ports are each connected to a storage tank and the connector may be a hose.
The outlets comprise a multiple port fuel manifold each connecting with corresponding fuel tanks of a fuel delivery truck. The inlets communicate with a corresponding storage tank. The connector has opposed couplings each with a ring mounting angularly spaced identifiers. The identifiers comprise a barcode or an RFID. At least two barcodes or RFIDs are disposed at angularly spaced locations around the coupling and rings snap onto the couplings. The outlets further have a plurality of angularly spaced barcodes or RFIDs. The inlets further have a plurality of angularly spaced barcodes or RFIDs.
Briefly stated, the connection line protection method comprises scanning a personal identification badge, associated with an operator, with a scanner and sending the information to a gateway terminal by a radio frequency network. The gateway terminal then sends a schedule to the scanner containing a first identifier of an outlet, a second identifier of an inlet, and a third identifier of a connector. The method then involves connecting the connector to the outlet and inlet and scanning the identifiers at the connections between the outlet and connector and inlet and connector. The connection line protection method then involves comparing the scanned identifiers with the schedule and emitting an audio or visual cue to alert the operator if the scanned identifiers do not match the schedule.
The connection line protection method further comprises scanning the first identifier on the outlet, the second identifier on the inlet, and the third identifier on the connector with the scanner and comparing the scanned identifiers with the schedule. The scanner emits an audio or visual cue to alert the operator if the scanned identifiers do not match the schedule. This method may further comprise collecting identifiers with the terminal to create the schedule. The connection line protection method may also include disposing at least two identifiers at angularly spaced locations around the connector at opposed couplings and snapping rings onto the couplings. At least two identifiers may be disposed at angularly spaced locations around the outlets and/or the inlets. Additionally, the connection line protection method may include storing the schedule in a memory of the scanner and storing the time scanned and the information contained in the personal identification badge in the memory. A location identifier associated with a location, information from the first identifier on the outlet, information from the second identifier on the inlet, and information from the third identifier on the connector may also be stored in the scanner.

FIG. 13 shows a schematic drawing of one embodiment of a handheld barcode scanning terminal with RF communications 315 an intelligent barcode ring 314, an intelligent quick connect hose barcode label 313, a charging cradle 326, and a power module 330.
The barcode scanning terminal 315 contains a microprocessor 322 that receives data from RFID scanner 525 which is transmitted to an RF transceiver and nonvolatile memory 325. The RF transceiver and/or nonvolatile memory 325 transmit data back to the microprocessor 322 and if the data is incorrect the microprocessor sends a signal to audio enunciator 323 to alert the operator. The microprocessor 322 also sends data to display 316 for the operator to read. The microprocessor 322 receives input from the operator through keys 321 on keypad 317.
The microprocessor 322 sends data to a gateway terminal (not pictured) through the RF transceiver. The barcode scanning terminal 315 receives data from the intelligent barcode ring 314 and the intelligent quick connect hose barcode label 313 through barcode scanner 318, which uses scanning beam 320.
The charging cradle 326 is electrically connected to power module 524 and contains magnet sensor 328, inductive transmitter 329, and inductive coils 331. When the magnet sensor 328 senses close proximity of magnet 327 in the barcode scanning terminal 315, the inductive transmitter 329 is switched to an on state to transmit electricity from power module 330 to an inductive receiver 332 in the barcode scanning terminal 315. This electricity is transmitted through inductive coils 331. The microprocessor 322 ultimately receives electricity from terminal battery 333 which is mounted in parallel with inductive receiver 332 and regulator 334.

The scheduler enters the sequence of hose removal from the previous day's operations and the hose installation required to transfer liquids from holding tanks to filling lines, for the next operation, on his terminal 401. The schedule is sent from terminal 401 by a local area network 402 to the host computer 403. The schedule is also sent via the local area network 402 to the gateway terminal 404, typically located near the hose connection room. The add/delete hose schedule is transferred via of the local RF network 405 to the barcode scanning terminal 315 cradled in the docking station 326. When the operator 542 starts the exchange of hoses, he first must send his personal barcode identification badge, which will be uploaded to the gateway terminal 404 via the RF network 406. He then will receive from the gateway terminal 404, a list of add and delete hoses. As he removes the hoses, as instructed, he scans the intelligent hose couplings and manifold ports; this event is then transmitted back to the gateway terminal 404 via the RF network 406.
If the operator removes the wrong hose, he receives an audio alert and a visual message on the barcode scanning terminal. As the operator installs the new required hoses, between intelligent tank ports and intelligent filling lines ports, he scans intelligent port and intelligent hose connector, at the same time to confirm that he is installing the correct hose on the correct port. The operator scans both ends of the hoses and their connections 335 and 336 to confirm that they were installed properly. When the correct installation is confirmed, the barcode scanning terminal 315 will transmit the status to the gateway terminal 404. As each requested connection is confirmed, a message is sent from the gateway terminal 404 to the host computer 403 via the local area network.
Also being shown is a handheld barcode scanning terminal 315 scanning a connection between intelligent hose 336 and intelligent manifold port assembly 335 which is connected to tank number five 114 and also scanning a connection between intelligent hose connector 336 and intelligent manifold port assembly 335 which is connected to fill line number two 115.

Again, this event is time stamped and stored in the nonvolatile memory in the RFID scanner 520.
As he connects intelligent hoses to the intelligent manifolds on the delivery truck 200, he must scan both the intelligent port 511 and the intelligent hose connection 516. This transaction is time stamped and stored in the nonvolatile memory in the scanning terminal 520. He is then instructed to scan the intelligent port 502 mounted to the underground tank 204 and the intelligent hose connection 516A. If this connection is correct, the event is time stamped and stored in the nonvolatile memory in the scanning terminal 520, and a positive audio alert will be emitted and a message to proceed to transfer liquids will be displayed on the scanning terminal 520.
When the hose is first connected to the tank 204 intelligent port and scanned with the handheld RFID scanner 520, the scanner display 536 will indicate the type of fuel in the tank. When the intelligent hose connection is scanned, it will light the orange LED 541, indicating that the intelligent hose has been identified. The operator is then instructed to scan the intelligent hose connection 516 and the intelligent tank port 511 after the connection has been made to ensure the correct product will be fed to the correct tank. If this connection is correct, the orange LEDs will turn to green indicating that it is correct connection. If the connection is incorrect, the LEDs will turn red, indicating that he has connected the intelligent hose to the wrong port.
It should be appreciated that the intelligent connection line protection system may be efficiently and easily implemented for use in properly connecting existing manifold ports and inlet lines via quick disconnect hose couplers and also for use in properly connecting fuel delivery truck outlets and underground fuel tank inlets via fuel hose adapter couplers. Precise angular orientation of the connections is not required in order to read the barcodes and/or the RFID tags. The use of the handheld scanners with communication capability allows for an immediate confirmation that a connection is correct or immediate input that the connection is incorrect. The scanner may be easily charged by a charger for the manifold port/inlet line application and may be easily charged through the electrical cigarette lighter or vehicle electric system for the fuel tank truck application. Additional information such as a time stamp for the hose connections and the identification of the installer may also be obtained through the connection line protection system.
While preferred embodiments of the foregoing connection line protection system have been set forth for purposes of illustration, the foregoing description should not be deemed a limitation of the invention. Accordingly, various modifications, adaptations and alternatives may occur to one skilled in the art without departing from the spirit and the scope of the present invention.
