The communication unit 220 transmits and receives signals required for the operation of the monitor device 200. [ Although the communication unit 220 transmits and receives signals to and from the vehicle terminal 300 through the communication network 110, a method of directly transmitting and receiving signals to and from the vehicle terminal 300 without using a separate communication network may also be used. Performing direct communication between devices without going through a separate communication network is called inter-device communication. In this specification, the communication network only serves to transfer signals between the vehicle terminal 300 and the monitor device 200, so that in the case of a signal transmitted only through communication, the reference to the communication network is omitted, Will be described focusing on the signal transmission between the devices 200. Fig.

The communication unit 220 receives the vehicle status information from the vehicle terminal 300 and transmits the status information to the control unit 250. The control unit 250 stores the received state information of the vehicle in the storage unit 230 and the state information of the vehicle to store the processed information in the storage unit 230. [ The communication unit 220 can receive a request message requesting processed information from the vehicle terminal 300. [ Upon receiving the request message, the communication unit 220 transmits a request message to the control unit 250. The control unit 250 acquires the processed information from the storage unit 230 according to the request message and transmits the processed information to the communication unit 220. The communication unit 220 transmits the processed information received from the control unit 250 to the vehicle terminal 300 that has transmitted the request message.

The control unit 250 controls each component of the monitor device 200. The control unit 250 can process the state information of the vehicle received from each vehicle terminal 300 and generate processing information. In addition, the control unit 250 may generate a response message, for example, a message including processing information, in response to the request message received from each vehicle terminal 300, and may transmit the message to the corresponding vehicle terminal 300.

The monitor device 200 may be configured substantially as one component, but may be implemented by two or more components. For example, the input unit 210 and the display unit 240 may be omitted, and an input signal may be provided to the monitor device 200 through a separate inquiry terminal, and an output screen may be provided. Also, the storage unit 230 may be replaced with a separately configured database server.

The specific configuration of the monitor device 200 will be described later in detail with reference to Figs. 4 to 6. Fig.

3 is a block diagram of a vehicle terminal 300 according to an embodiment of the present invention.

3, a vehicle terminal 300 according to an embodiment of the present invention includes an input unit 310, a communication unit 320, a storage unit 330, a display unit 340, a control unit 350, a speaker 360, And a sensor unit 370.

The input unit 310 receives a user input and transmits the input to the control unit 350. The input unit 310 may be implemented using at least some of a keyboard, a keypad, a mouse, and a touch screen or other input device, for example. The input unit 310 can receive an operation command of the vehicle driver, a message that the vehicle driver sends to the driver of another vehicle, or a work completion input.

The communication unit 320 transmits and receives a signal necessary for the operation of the vehicle terminal 300. The communication unit 320 generally exchanges signals with the monitor device 200 through the communication network 110. Alternatively, the communication unit 320 may transmit and receive signals directly to the monitor device 200 without using a separate communication network.

The communication unit 320 may transmit a request message requesting the processed information to the monitor apparatus 200. [ Also, the communication unit 320 can receive the processed information corresponding to the request message from the monitor device 200. [ According to some embodiments, the communication unit 320 may transmit a signal corresponding to an input of the vehicle operator to another vehicle terminal according to an input message of the vehicle driver and / or an input of a work completion of the vehicle driver. In this case, the signal may be transmitted via the monitor device 200 or directly to another vehicle terminal.

The storage unit 330 stores information necessary for the operation of the vehicle terminal 300. [ The storage 330 may be implemented in the manner of at least some of, for example, a magnetic disk, a random access memory (RAM), or other electromagnetic storage medium. The storage unit 330 may store the collected state information of the vehicle temporarily or semi-permanently. In addition, the storage unit 330 may temporarily or semi-permanently store signals received from the monitoring device 200 or other vehicle terminals.

The display unit 340 displays the machining information received from the monitor device 200 and the status information of the vehicle. For example, the display unit 340 may display the current vehicle arrangement status in a map form. The display unit 340 may display the progress of the vehicle on which the vehicle terminal 300 is mounted in a text form. The display unit 340 may display a warning about an accident risk or a notification of an accident occurrence. The display unit 340 may be implemented using, for example, a liquid crystal display (LCD), a light emitting diode (LED), or other at least some of currently known or future known display schemes. The display unit 340 may display at least a part of the position, movement, and operation state of other vehicle terminals in the same group to which the vehicle terminal 300 belongs. The monitor device 200 can provide the vehicle terminal 300 with information regarding the location, movement, and operation status of other vehicle terminals. When the user selects a specific vehicle, the display unit 340 can display information about the selected vehicle. The information about the selected vehicle may include, for example, state information including at least a portion of the vehicle's position, speed, consumption fuel, travel distance, and travel speed, and / or machining information extracted using the state information .

The control unit 350 controls each component of the vehicle terminal 300. The control unit 350 may be implemented as a part of the control unit of the vehicle, or may be implemented in a configuration separate from the control unit of the vehicle. The control unit 350 receives the status information from the sensor unit 370 and transmits the status information to the monitor device 200 through the communication unit 320. [ The control unit 350 can generate a request message according to the input of the user and transmit the request message to the monitor device 200 through the communication unit 320. [ The control unit 350 may convert the processed information received from the monitor device 200 through the communication unit 320 into a visual and / or audible signal and output it through the display unit 340 and / or the speaker 360 have.

The speaker 360 outputs an audible signal. In particular, the speaker 360 can output a warning signal indicating an accident risk or an accident occurrence. In addition, when the communication unit 320 receives the operation completion signal from another vehicle terminal, the speaker 360 can output a sound indicating the completion of the operation.

The sensor unit 370 senses the state information of the vehicle on which the vehicle terminal 300 is mounted and transmits the state information to the controller 350. The state information of the vehicle may include, for example, vehicle speed, position information, fuel consumption, and other collectable information. The control unit 350 transmits the received status information to the monitor device 200 or displays the received status information through the display unit 340. The display unit 340 may serve as an instrument panel.

The vehicle terminal 300 may be constituted of substantially one component, but it may be implemented by being divided into two or more components. For example, the vehicle terminal 300 may receive only the sensing result signal from the sensor unit of the vehicle and / or the control unit of the vehicle without including the sensor unit 370 directly. Also, the vehicle terminal 300 may not include some of the input unit 310, the display unit 340, and the speaker 360 according to the embodiment. In this case, the input / visual output / audible output function of the vehicle terminal 300 may be partially limited.

The vehicle terminal 300 may be implemented, for example, in the form of a traffic management system (TMS) terminal, but may also be implemented in other types of terminals.

The specific configuration of the vehicle terminal 300 will be described later in detail with reference to FIG. 4 to FIG.

4 is a flowchart of vehicle monitoring information providing process according to an embodiment of the present invention.

Referring to FIG. 4, at step 410, the first vehicle terminal 132 obtains status information. Here, only the position information of the vehicle in the state information is referred to. However, the status information may include at least some of the vehicle's speed, fuel amount, fuel consumption, workload, vehicle attributes, vehicle type, vehicle distance, vehicle usage mode, component anomaly, and other collectable information. The status information can be acquired / sensed through the sensor unit 370. The location information may be obtained via the GPS module. The speed information can be obtained through the speedometer of the vehicle. The fuel amount and / or the fuel consumption amount can be obtained through the fuel sensor of the vehicle fuel tank. The information such as the attribute and the kind of the vehicle can be set by the driver or the system operator. The workload information of the vehicle can be obtained through the driver's input (work completion input, workload input) or the weight sensor of the stationary member. The component anomaly information can be obtained by a module that checks for component anomalies.

In step 415, the first vehicle terminal 132 transmits the obtained status information to the monitor apparatus 200. [ In step 420, the monitor device 200 collects the received status information. For example, the monitoring device 200 stores vehicle status information corresponding to the terminal in the database. Transmission and reception of status information can be performed periodically. In step 425, the monitor device 200 updates the processing information according to the collected status information. The processing information may include, for example, current position information of the entire vehicle. If the position information corresponding to the first vehicle terminal 132 is changed in accordance with the movement of the vehicle, the processing information may be changed accordingly.

At step 430, the second vehicle terminal 134 obtains status information. Here, only the position information of the vehicle in the state information is referred to. The status information can be acquired / sensed through the sensor unit 370.

In step 435, the second vehicle terminal 134 transfers the obtained status information to the monitor apparatus 200. [ In step 440, the monitor device 200 collects the received status information. For example, the monitoring apparatus 400 stores vehicle status information corresponding to the terminal in the database. Transmission and reception of status information can be performed periodically. In step 445, the monitor device 200 updates the processing information according to the collected status information. The processing information may include, for example, current position information of the entire vehicle. If the position information corresponding to the second vehicle terminal 134 is changed in accordance with the movement of the vehicle, the processing information may be changed accordingly.

The process of steps 410 to 445 may be performed periodically for all the vehicle terminals 300 that are active in the system. The vehicle terminal 300 periodically acquires status information and transmits the status information to the monitor apparatus 200. The monitor device 200 receives and stores the status information and updates the processing information on the basis of the stored status information. Accordingly, the monitor device 200 can keep the state information and the processing information of each vehicle up to date.

Then, in step 450, the first vehicle terminal 132 transmits a message requesting processing information to the monitor device 200. The message requesting the machining information may include, for example, an identifier identifying the type of machining information. If the requested machining information is statistical information, the message requesting machining information may further include identification information (group, vehicle, period, etc.) of the specimen.

For example, when the vehicle driver inputs a command to request the placement status of the current vehicle through the first vehicle terminal 132, the first vehicle terminal 132 transmits a message requesting the vehicle position information to the monitor device 200 .

In step 455, the monitor device 200 provides the first vehicle terminal 132 with processing information corresponding to the request message. For example, the monitor device 200 may communicate current vehicle location information to the first vehicle terminal 132. [

In step 460, the first vehicle terminal 132 displays the received vehicle position information through the display unit 340. [ Here, the position information of the vehicle includes the position information of the active vehicle in the system, and the display unit 340 may display the position of each vehicle in the form of a map. The vehicle closest to the first vehicle terminal 132 can be distinguished from other vehicles. In addition, icons, texts, and the like can be classified according to the type of each vehicle (excavator / truck, etc.). When group information is used as described later, the vehicle of the same group as the vehicle of the first vehicle terminal 132 may be displayed so as to be distinguished from the other group of vehicles.

Here, although the example of the transfer of the one-time location information is described, when the vehicle terminal 300 requests the transfer of the repeated position information, the monitor apparatus 200 repeatedly transmits the position information of the vehicles in the system To the corresponding vehicle terminal (300).

According to a variant, the driver of the second vehicle terminal 134 may input a command to request the travel distance information of the vehicle corresponding to the second vehicle terminal 134 for a certain period of time. In this case, the second vehicle terminal 134 transmits a request message including the identification information of the period inputted by the driver to the monitor device 200. [ The monitor apparatus 200 can obtain the total travel distance of the vehicle during the corresponding period in such a manner that the travel distance of the second vehicle terminal 134 of each date during the corresponding period is summed (i.e., the travel distance of the corresponding vehicle) . The statistical information of a specific unit such as a day, a month, and a year can be generated and stored by the monitor apparatus 200 without a separate request. However, the statistical information for another arbitrary period may be calculated / generated by the monitor device 200 according to the request of the vehicle terminal 300 and provided to the vehicle terminal 300. According to another embodiment, the vehicle terminal 300 requests basic information for extracting the requested machining information from the monitor device 200, and the vehicle terminal 300 generates machining information based on the received basic information, You may. That is, the vehicle terminal 300 requests the monitor device 200 for the moving distance information of each date during the corresponding period, and the vehicle terminal 300 adds the moving distance information of each date to the total moving distance information for the corresponding period Can be generated.

The monitor device 200 can extract the remaining time until the next task of the specific vehicle by using the current position and speed of the vehicle belonging to the same group and the past work time statistics.

Suppose one commuter excavator and one mobile truck belong to the same group. In this case, after the commuter excavator completes the loading on the truck, the truck moves the loaded soil or load to the loading position. At this time, data such as the moving distance and speed to the loading position of the truck, the loading start time and the loading end time at the loading position are transmitted to the monitor apparatus 200. The monitor apparatus 200 can calculate the time required for the movement using the distance from the current position of the truck to the destination and the speed of the truck. In addition, the monitor apparatus 200 can estimate the time that the truck will spend on the next truck, using the work time spent from the start of loading to the end of loading of the old truck. The monitor apparatus 200 estimates the movement time and the work time required for the movement and adds the estimated travel time and the work time so that the excavator can obtain the remaining free time before the next operation. The spare time information is provided to the vehicle terminal mounted on the excavator, and the vehicle terminal can display the spare time information through the display unit. The driver of the vehicle can refer to the spare time information and process the urgent service or wait while taking a proper rest.

In another example, it is assumed that one commuter excavator and several moving trucks form a group. The monitor device 200 can know the pattern of the moving truck and can confirm whether it is a movement for loading or a movement for loading or unloading. In the case of a work site that sequentially carries out work, By checking, you can check the time remaining until the next operation of each truck and excavator.

The processing information may include group information. Two or more vehicles can work together in groups. For example, if an excavator dug soil and put it on a truck, the way the truck relocates the soil can be applied. In this case, excavators and trucks should be managed in one group. Such group information may be generated manually by the driver and / or the system operator. Also, group information may be generated / changed in the same manner as in FIG. 6 described later. In the embodiment of FIG. 5, it is assumed that the group information has already been generated.

5 is a flowchart of a completion message delivery process according to an embodiment of the present invention.

In the example of FIG. 5, the two vehicle terminals 132 and 134 belong to one group. Since the two vehicle terminals 132 and 134 perform the same operation, mutual communication is required. A complicated message may be sent and received between the two vehicle terminals 132 and 134, but most importantly, the completion of a specific work step is signaled. For example, if an excavator informs the truck that the work is complete after the truck is filled with dirt, the truck may start to the destination for the dirt transport. The use of mobile phones, the way people shout, and the way the beeps sound can be used. However, in a noisy construction site, the use of mobile phones is inconvenient, and there is a danger that the voice of a person will not be heard. In addition, horns should be used as a signal of danger, so there is a problem that if they are mixed for other purposes, the danger prevention function is lost or the risk prevention function is reduced.

Referring to FIG. 5, in step 510, the first vehicle terminal 132 receives a work completion input. The vehicle operator of the first vehicle terminal 132 can command the work completion input using the touch screen or other buttons. When the first vehicle terminal 132 receives the job completion input, it sends a completion message to the second vehicle terminal 134 in step 520. [ When the second vehicle terminal 134 receives the completion message, the second vehicle terminal 134 outputs a completion alarm in step 530. [ The second vehicle terminal 134 may output a completion alarm, for example, via the display unit 340, and / or output a completion alarm via the speaker 360. [ Lamps or other output devices may be utilized. When the speaker 360 is positioned in the cab, the driver can clearly recognize the completion alarm without being disturbed by the external noisy sound.

The first vehicle terminal 132 can send a completion message to the other terminals 134 in the group when the first vehicle terminal 132 receives the work completion input when there are only two vehicle terminals 132 and 134 in the group .

When there are several vehicle terminals in the group, the first vehicle terminal 132 can transmit a completion message to all other terminals in the group when the first vehicle terminal 132 receives the job completion input.

According to another embodiment, when the first vehicle terminal 132 receives the work completion input, the first vehicle terminal 132 identifies the vehicle terminal closest to the first vehicle terminal 132 of the other vehicle terminals in the group, The completion message can be transmitted to the vehicle terminal. In this case, there is an advantage that a message can be transmitted to the vehicle terminal performing the direct operation together.

According to another modification, when the first vehicle terminal 132 receives the job completion input, the first vehicle terminal 132 transmits the preset number of the first vehicle terminal 132 in the closest order to the first vehicle terminal 132 in the group Multiple) vehicle terminals and send a completion message to the identified vehicle terminals. For example, when a completion message is transmitted to two vehicle terminals, a completion message can be transmitted to a vehicle terminal participating in the current task and a terminal waiting for the next turn.

According to another variant, the first vehicle terminal 132 provides an interface for selecting another vehicle terminal (vehicle) in the group, and when the user selects a vehicle terminal, the first vehicle terminal 132 is selected The completion message can be transmitted to the vehicle terminal.

In the embodiment of FIG. 5, it is assumed that the two vehicle terminals 132 and 134 send and receive messages directly. However, a message may be transmitted through the monitor device 200. This scheme can be used when it is difficult to implement a direct communication scheme between the vehicle terminals 132 and 134. [ In this case, the vehicle terminal can simply deliver a message to be transmitted to the monitor device 200, and the monitor device 200 can identify the terminal in the same group as the terminal that transmitted the message, and deliver the message to the identified terminal. In addition, the monitor device 200 can identify a predetermined number of vehicle terminals in the closest order, or a terminal closest to the terminal that transmitted the message, and transmit the completion message to the identified vehicle terminals. When the monitor device 200 participates in message transmission / reception between vehicle terminals, the monitor device 200 can also participate in the identification of the message recipient.

6 is a flowchart of a group update procedure according to an embodiment of the present invention.

In step 610, the monitor device 200 determines whether the distance between the two vehicles (vehicle terminal) is within a predetermined distance (for example, 10 meters). If the distance between the two vehicle terminals is not within a predetermined distance, the process returns to step 610 again. If the distance between the two vehicle terminals is within the predetermined distance, the process proceeds to step 620. [

In step 620, the monitor device 200 determines whether the two vehicle terminals are vehicle terminals belonging to the same group. If the two vehicle terminals are vehicle terminals belonging to the same group, the process returns to step 610. [ If the two vehicle terminals do not belong to the same group, the process proceeds to step 630.

In step 630, the monitoring device 200 determines whether the proximity period of the two vehicle terminals exceeds a predetermined period (for example, one minute). Wherein the proximity period is a period in which two vehicle terminals are continuously located within the predetermined distance. If the proximity period of the two vehicle terminals does not exceed the preset period, the process proceeds to step 650. [ In step 650, the monitoring device 200 transmits a warning message to two nearby vehicle terminals. The vehicle terminals receiving the warning message output the alarm through the display unit 340 and / or the speaker 360. [ The driver can prevent the risk in advance. If the proximity period of the two vehicle terminals exceeds a predetermined period, the process proceeds to step 640. [ If the two vehicle terminals are kept in a state of being close to each other for a predetermined period of time, it can be determined that the vehicle terminal is associated with the vehicles performing the same operation. Accordingly, the monitor device 200 adjusts the group information so that the two vehicle terminals belong to the same group. The process from step 610 to step 650 is repeated periodically. When two vehicles approach the time, the danger alarm is provided first, and then the alarm belongs to the same group and is no longer provided. When the group information is updated, the two vehicle terminals can transmit and receive the completion message and other messages to each other as described with reference to FIG.

When the vehicle terminal directly transmits a message to the group to which the vehicle terminal belongs, the monitor device 200 can notify the vehicle terminal of the group of the updated group information of the group when the group is updated. However, when the vehicle terminal transmits the message to the monitor device 200 and the monitor device 200 transmits the group information to the group of the vehicle terminal, the monitor device 200 does not need to transmit the group information to the vehicle terminal .

The monitor device 200 can check the status of each vehicle by collecting the received data, and can confirm the operation time, fuel consumption amount, work amount, etc. of each group, and can process the data to calculate the daily operation time and work amount You can check in advance. System operators and vehicle operators can use this information to refer to the operation and operation of the workplace.
