Definitions
- This invention relates to an apparatus and method for tracking a vehicle and, more particularly, to an apparatus and method wherein the location of a vehicle is recorded during a predetermined event.
- a wide variety of tasks are performed using vehicles. These often include pickup and delivery of persons or goods. It is sometimes desirable to have a record of the time and place of the performance of these tasks.
- Various methods exist for creating such records These typically consist of simple handwritten logs kept by drivers of the vehicle, such as those commonly used by truck drivers.
- One of the disadvantages of existing systems for recording a vehicle's position is that they generally require manual action on the part of the driver. This can result in the recording of incorrect information or the omission of information, either unintentionally or intentionally. For this reason, it would be desirable to have a system which can determine the location of a vehicle automatically without requiring any action on the part of the operator.
- LORAN systems In general, there are various systems which have been used for determining the location of a vehicle. These include LORAN systems and Global Positioning Systems (GPS) . These systems rely on externally transmitted radio frequency signals to calculate the location of a receiving antenna mounted on the vehicle. In LORAN systems, this calculation is based on the time difference in signals received from multiple transmitters. Because the latitude and longitude of the transmitters are known, the distance from two or more transmitters can be calculated from the time lag between the reception of the plurality of signals. The resulting calculation can determine the latitude and longitude of the receiving antenna to within approximately plus or minus 20 feet.
- GPS Global Positioning Systems
- GPS Another type of navigational system is the GPS system.
- the transmitters are positioned on orbiting satellites. Time and location information of the satellites plus the doppler shift of the radio frequency signal received from the satellite is used to calculate the location of the receiver.
- GPS systems can determine location with even greater accuracy than LORAN systems.
- a vehicle is equipped with a navigational system such as a GPS or LORAN type system.
- the vehicle also is equipped with a sensor or sensors that are automatically switched upon the occurrence of a predictable or predetermined event.
- this sensor may be a switch that closes when the passenger door of a taxi cab or bus is opened or closed.
- the placement of the sensor will vary depending on the particular type of information desired, and the purpose of the tracking system.
- the sensor will then trigger the navigational antenna system causing it to receive and process signals containing navigational information. This will permit calculation of the position of the vehicle at that time.
- the vehicle in accordance with the invention, is also equipped with a data collector that has the capability of storing this information along with the time and date of the recording of the information, as well as a full identification of that specific vehicle.
- the stored information can then be downloaded to a data processing system and accessed immediately, or at a later time and also analyzed to determine the exact location and time of the occurrence of the events.
- the present invention is useful in a number of applications. These include recording the location of each pickup and dropoff point of passengers of busses and taxi cabs; recording locations of trucks or railroad cars at various times; tracking deliveries of delivery trucks and vans; tracking the location of police cars and fire trucks and other applications where recording vehicle location and event history is desirable.
- To adapt the present invention to each individual application would simply require the configuring of a switch or sensor to record the occurrence of the desired event.
- the switch may be responsive to the opening or closing of a door.
- the event may simply be the passage of an interval of time.
- the present invention is particularly useful in the waste disposal business. It is a common problem in commercial and industrial waste disposal that the location and time of each pickup and of each dump by the garbage truck is not always known. This creates a number of difficulties, such as in determining the correct billing for each customer. It has been found that it is not practical to require the driver to keep records of the time and location of each pickup and dump. For this reason, it would be desirable to have a system which automatically records the time and place of each pickup and the time and place of each dump.
- a further advantage of the present invention in the field of waste disposal is the ability to monitor the exact location of the dumping of hazardous waste.
- hazardous waste At present, it is possible for hazardous waste to be dumped from a garbage truck at an unauthorized or unknown location. This situation can create serious environmental problems.
- Using the present invention when hazardous waste is picked up from a particular location, regardless of whether the waste is known to be hazardous or not, there will be an exact record of the location of the pickup and also an exact record of any subsequent dumping of that waste.
- These records will benefit the persons disposing of the hazardous waste because they will know where his hazardous waste ends up.
- the records will also benefit the dump site owner because he will know, with certainty, the source of waste dumped at his dump site.
- the waste hauler will benefit from the ability to monitor the exact location and sequence of activities of his garbage trucks.
- One embodiment of the present invention may be used to determine the source of waste products of unknown origin.
- the navigational system is used to determine the location of the truck during pickup of waste. This information is then transferred to a portable identification tag which stores the information. The identification tag then is placed in the waste. At a later time, an RF transmitter and receiver is brought within proximity to the identification tag and transmits an activating RF signal to the tag. This causes the tag to transmit its stored information to the RF transmitter and receiver. In this way, the source of the waste can be determined.
- Figure 1 is a view pictorially illustrating the various components of the invention embodied in a waste collection and disposal system.
- Figure 2 is a flow chart illustrating some of the general steps used to carry out the method of this invention.
- Figure 3 is a view pictorially illustrating the waste collection and disposal system of Figure 1 with the identification tag.
- the garbage truck 10 is of the type commonly used for commercial and industrial waste hauling.
- the garbage truck 10 includes a refuse compartment 12 and a lift arm 14.
- the lift arm 14 pivots on an axis 16 and is used to lift a commercial refuse container.
- the contents of the dumpster are emptied into the open top of the refuse compartment 12 in the usual manner.
- Motion of the lift arm 14 as it dumps the contents of the dumpster is sensed by a sensor 18.
- This sensor 18 may consist of a variety of electromechanical or optical sensors capable of making or breaking an electrical contact in response to the lifting motion of the lift arm 14.
- sensor 18 on the lift arm 14 comprises a mercury sensor in which the tilting motion of the lift arm 12 causes motion of liquid mercury to complete an electrical circuit when the dumpster is picked up and emptied into the refuse compartment 12.
- the garbage truck refuse compartment 12 is also provided with a tailgate or rear door 20 to facilitate emptying the refuse compartment 12. This is accomplished by tilting the entire refuse compartment 12 rearward, or by pushing the refuse out of the compartment 12 by mechanical means, whereupon rear door 20 rotates away from refuse compartment 12 about an axis 22. This permits the contents of the refuse compartment 12 to fall out of the compartment at an appropriate waste dump site. Motion of the rear door 20 is sensed by an appropriate sensor 24 mounted on the refuse compartment 12. This sensor 24 is a mercury sensor which is mounted so that when the refuse compartment 12 tilts to permit emptying, an electrical circuit is completed by the mercury sensor 24.
- Both the lift arm sensor 18 and the rear door sensor 24 are coupled electrically to a navigational system.
- this will comprise a GPS-type navigational system 26.
- Both sensors 18 and 24 are coupled to a data collector 28.
- the GPS system 26 is preferably mounted with its antenna on the roof on the cab of the garbage truck 10 and uses signals received from navigational satellites to calculate the latitude and longitude of the truck 10 at any given time.
- Data collector 28 is preferably a microprocessor- type circuit which is coupled to both sensors 18 and 24 and also to the GPS system 26.
- the data collector 28 is capable of receiving and storing the latitude and longitude positional information from the GPS system 26. This information is stored when either the lift arm sensor 18 or the rear door sensor 24 are activated.
- the data collector 28 is also capable of distinguishing whether the positional information stored corresponds to the activation of the lift arm sensor 18 or the rear door sensor 24.
- the identification of lift arm 14 motion and rear door 20 may be accomplished by assigning a first code to positional information received when the lift arm sensor 18 is activated and assigning a second code to positional information received when the rear door sensor 24 is activated.
- the data collector 28 also comprises a clock that permits it to also assign a date and time to the positional information each time such information is recorded.
- the data collector 28 also contains an interface port to permit transfer of data to an external processor.
- the garbage truck 10 also has a passive radio frequency transmitter or tag 30 mounted to it.
- a tag manufactured by Allen-Bradley as part of its RF Identification System may be used for the tag 30. (See, eg Allen-Bradley publications 2750-1.0 dated April, 1983 and February, 1984) .
- One use of such an identification tag is described in U.S. Patent No. 4,688, 026 issued to James R. Scribner et al.
- this transmitter 30 is capable of transmitting the truck identification number to a base data receiver/computer unit 32 by means of radio frequency transmission.
- the data receiver/computer 32 is located at the depot where the truck is returned and kept when not in use.
- an RF signal from the receiver/computer unit 32 causes the tag 30 to transmit the truck identification number to the receiver/computer unit 32.
- the information contained in the data collector 28 may then be downloaded into the base receiver unit 32.
- This information will consist of coded information comprising: 1) the identification number of the garbage truck 10; 2) the date, time and latitude and longitude of each occurrence of the lift arm 14 lifting and emptying a refuse container; 3) date, time, latitude and longitude of each occurrence of the rear door opening to unload the contents of the refuse compartment 12.
- the data receiver/computer unit 32 also has data computing and storing capabilities. This permits the data receiver/computer unit 32 to store latitude and longitude information for each known pickup and dump location as well as the name and address of that location. Upon receiving the aforementioned data from the garbage truck 10, the receiver/computer unit 32 will first compare the latitude and longitude of actual pickup and dump sites with those of the stored known sites. The receiver/computer unit 32 will then match up the two and tabulate a chronology of the day's activities of the truck. This will include the name, address, time and date of each pickup of each dump. Finally, this information will then be analyzed, utilized or displayed in the manner desired.
- a portable RF identification tag 62 capable of storing positional information, may be placed in the waste itself.
- This tag may be similar to the aforementioned tag 30.
- This tag 62 is also capable of transmitting positional information when energized by an external RF signal.
- the date, time, vehicle identification code and positional information may then be transmitted directly from the data collector 28, or other source of positional information, into the identification tag 62.
- the RF identification tag 62 will then be placed in the hazardous waste itself.
- an RF transmitter antenna and receiver is placed sufficiently clsoe to the tag and RF energy from the transmitter antenna and receiver will then energize the identification tag 62 and cause it to transmit the positional information it contains.
- the RF transmitter and receiver then will receive and store, or display, the positional information. This information may be used to determine the source of the hazardous waste. In this way, hazardous of unknown origin can be traced to its source.
- Figure 2 there is shown a flowchart illustrating the steps performed by the various components to achieve the advantages of the present invention. Initially, the garbage truck 10 leaves the depot as indicated by step 34. An RF signal from the receiver/computer 32 will cause the identification tag 30 to transmit a signal containing the vehicle identification number, as indicated by step 36.
- the garbage ruck 10 will then proceed to pickup sites where the ligt arm 14 will be utilized in emptying refuse containers into the truck 10.
- the lift arm sensor 18 senses this motion (step 38) .
- the activation of sensor 18 will cause the navigational system to receive and compute positional data (step 40) .
- This information will then be transmitted to the data collector 28 which will generate the date, time, vehicle identification and sensor code data (step 42) .
- This data, along with the positional data, will then be recorded by the data collector (step 44) .
- the vehicle will then likely repeat steps 38, 40, 42 and 44 as successive pickups are accomplished.
- the weight of the truck may be optionally entered (step 46) .
- rear door or tail gate sensor 24 will then be activated by motion of the rear door or tail gate sensor 24 will then be activated by motion of the rear door (step 48) .
- the activation of the rear door sensor 24 will then cause the navigational system to receive data, (step 40) and the data collector to compute date, time, vehicle ID and sensor code (step 42) .
- the data collector will then store this information (step 44) .
- the truck 10 may then proceed to additional pickup sites (steps 38 through 44) and additional dump sites (steps 46, 48, 40, 42 and 44).
- the truck 10 will return to the depot (step 50) , where upon the identification tag 30 will transmit the vehicle identification number (step 52) .
- the depot receiver/computer unit 32 will then compute the time, date information (step 54) and then record this data along with the vehicle identification number and time and date of the truck and departures and arrivals (step 56) .
- the data stored in the data collector 28 will be downloaded into the data receiver/computer unit 32 and the data collector 28 memory will be cleared (step 58) .
- the data in the receiver/computer unit 32 may then be analyzed and utilized in the desired manner (step 60) .
