Example

The present patent relates to a vehicle location tracking device and system for managing specification information and location of a vehicle using a wireless communication network and a data management computer 100 to which a mobile location recognition device 300 and a communication base station 200 are connected.

The entire system overview is shown in FIG. Is the same as A location recognition device 100 for collecting and transmitting location information of a vehicle, a base station device 200 constituting a location data recognition device and a wireless data communication network, and a base station device connected to collect, store, manage data, and control messages required. The data management computer 100 for transmitting the data is minimized. The base station device is connected to the data management computer by wire or wireless network.

The position recognition device is a GPS receiver 31 for generating location information by carrying a vehicle, a person carrying a vehicle, or attaching it to a vehicle, and allowing a vehicle manager to display vehicle specification information, location information, and the like from a data management computer. Message display device 32 for displaying the received message, etc., storage device 33 for storing the information, barcode reader or RF-tag reader for reading the specification information of the vehicle from a barcode or RFID tag attached to the vehicle 34, a timer 37 for activating the radio transceiver and / or the main controller according to a predetermined time, for activating the radio transceiver and the main controller, a shock sensor 38 for detecting the movement of the vehicle, and a data management computer through a communication base station. And a main transceiver 35 for controlling the functions of the above components and a wireless transceiver for transmitting and receiving functions as shown in FIG. .

The GPS receiver 31 in the location recognition device 300 is a navigation device that obtains location information such as longitude, latitude, and altitude using a GPS satellite signal. The GPS receiver 31 may determine the current location of a vehicle or the location of a vehicle manager using this data. Make sure The barcode reader or RF-tag reader 34 is for obtaining vehicle details of a barcode or RF-tag attached or installed on the vehicle, and the information is stored in the storage device through the master controller 35. When not using a barcode or RF-Tag, it is possible to store the specification information in the storage device of the positioning device using the input wireless transceiver 36 in the data management computer at the production or vehicle yard management stage. The display device 32 expresses a signal in response to a command of a message transmitted from a data management computer, and turns on an LED or expresses a certain voice message. For example, if a data management computer sends a message such as LED lighting or blinking to a vehicle that is to be shipped at night, it can be tracked by turning on the LED at the vehicle's location recognition device that meets this condition. By providing a voice message to the car as an LED flashing light, it is easy to identify the vehicle to find. In addition, the shock sensor 38 detects the start and end of the movement of the vehicle. The simplest form may be a shock sensor, but may be replaced by another movement detecting means.

Figure 3. The communication base station 200 is a wireless transceiver 36 constituting a communication link with the position recognition device 300, the main controller 22 to control the overall operation, and a wired or wireless network device for connecting to the data management computer Is the default configuration. In order to increase the position detection performance of the position recognition device, a DGPS reference station 23 for generating position correction information may be added.

The following describes the main functions of each component in detail.

First, a method of transmitting location information when a location recognition device that reads and stores information stored in a barcode or an RF tag is attached to a vehicle and used is described.

It will be described how the position recognition device 300 attached to the vehicle determines the movement of the vehicle and transmits the final position after the movement is completed. At this time, the position recognition device may use its own battery or the battery of the vehicle, and the vehicle may be piled up for several months, so the battery power consumption should be minimized. For this purpose, the main controller 35 operates in a standby mode (or sleep mode) that consumes minimal power. In the standby mode, the shock sensor detects a shock due to the movement of the vehicle and transmits a shock signal to the main controller 35. The main controller 35 is activated by the shock signal and monitors whether or not additional shocks are input for a predetermined time after the shock is generated. If there is no additional impact, the vehicle will move and determine that it has been stowed at a certain location, turn on or activate the GPS in OFF or Standby state and collect the location information. When the location information is collected, turn on or activate the wireless transceiver 36 in the OFF or standby state again, and transmit the data including the position data.After this procedure, only the shock sensor 38 is activated and the main controller and the like are in standby. Or return to OFF. When the communication base station 200 receives this data, it transmits the same data back to the data management computer 100 and the management computer organizes and stores this data. In the data transmission procedure, when the communication base station 200 receives the data normally, it transmits an acknowledgment signal indicating that the data has been correctly received to the position recognizing apparatus 300, and if there is no confirmation signal, further transmits the data again to increase communication reliability. It can be done together.

Next, a method of periodically transmitting the position of the vehicle in the position recognition apparatus 300 attached to the vehicle will be described.

Normally, only a timer inside or outside the main controller 35 operates to reduce battery power consumption, and the main controller 35 has only a function of receiving a signal from the shock sensor 38. In addition, the GPS receiver 31 and the radio transceiver 36 are in an OFF or inactive state. In the timer 37, a position transmission cycle is set. When the timer operates to reach a certain count, the main controller 35 in the standby state is activated. The activated main controller sends the location information by turning on or activating the GPS and the wireless transceiver as described in the above-described procedure.

In the above, a method of transmitting location information and the like from the location recognition device 300 to the communication base station 200 to the data management computer 300 has been described. Here, the data management computer 100 operates as the location recognition device 300. Describes how to send and receive commands or data. In general, since the main controller and the wireless transceiver are in a normal operation state, no special design is required, but in the case of the use of the present invention, power consumption should be minimized even during a message reception process.

First, the position recognition device 300 activates only the timer 37. When the timer reaches a predetermined period, the position recognition device 300 activates the radio transceiver 36 or both the radio transceiver 36 and the main controller 35. The activated radio transceiver activates the radio reception function for a certain time. If there is no message received during this time, it returns to the previous state and repeats the activation process by the timer. As shown in Fig. 4, the data management computer 100 repeatedly transmits the same data when there is a message to be transmitted to the location recognition device 300. The amount of time for repetitive transmission of the data may be about several times the reception period of the location recognition device if the location recognition device is known to be activated. When the next wireless transceiver 36 receives the message of the data management computer, the subsequent operation is performed according to the contents of the received data, and is restored to its original state after completion of the subsequent operation.

Next, a method of managing the location information of the vehicle and the like while holding the location recognition device 300 again will be described.

In this case, the position recognition device can be configured except the timer or the shock sensor in the original configuration. The vehicle manager reads information about the vehicle by using a barcode reader or an RF-tag reader 34 when the vehicle is parked in a yard or additional movement occurs. This information is input to the main controller 35, and the main controller is configured to transmit data by transmitting the position information of the GPS and the vehicle information read above to the radio transceiver 36. This data collection and transmission process can be configured to be processed automatically by simply reading the barcode or RF-ID contents, so that the vehicle manager can cope with mistakes such as forgetting to transmit the data and increase the efficiency of the system.

The present invention can be used not only to track the vehicle position of the yard, but also useful for the management of other assets such as containers and cargoes.
