Description

Articulated vehicle connection identification system and method

The present invention relates to an articulated vehicle connection identification system and method thereof, and in particular to an articulated vehicle connection identification system and method thereof for identifying an articulated vehicle.

In transportation, in order to facilitate the transportation and unloading of large goods, large trucks can be divided into an articulated truck as the front of the vehicle and an articulated sub-truck that carries the goods. Each articulated sub-truck has a license plate number for users to confirm. However, in general, the user manually confirms the articulated sub-truck to which the articulated truck is connected. Therefore, due to human error, the articulated truck may be connected to an articulated sub-truck that is not the target of the transportation. The error is not discovered until the vehicle reaches the unloading location, resulting in unnecessary time costs.

In view of this, a vehicle connection identification system and method for users to identify the vehicle is still a common goal of the relevant industry.

The purpose of the present invention is to provide an articulated vehicle connection identification system and method thereof. Through the configuration of a signal identification module and an identification signal sending module, the articulated vehicle can receive a sub-vehicle identification signal from a connected sub-vehicle so that a user can confirm the connected sub-vehicle connected to the articulated vehicle.

According to one embodiment of the present invention, a connection identification system for an articulated vehicle is provided, which includes an articulated vehicle and a plurality of articulated sub-vehicles. The articulated vehicle includes an articulated vehicle body, a plurality of articulated vehicle wheels, and a signal identification module. The articulated vehicle wheels and the signal identification module are disposed on the articulated vehicle body. Each articulated sub-vehicle includes a sub-vehicle body, a plurality of sub-vehicle wheels, and an identification signal sending module. The sub-vehicle body is used to detachably connect the articulated vehicle, and the sub-vehicle wheels are disposed on the sub-vehicle body. The identification signal sending module is disposed on the sub-vehicle body and is used to send a sub-vehicle identification signal to the signal identification module. When the signal recognition module receives a sub-vehicle identification signal, the signal recognition module determines the identification code of a coupled sub-vehicle connected to the coupled vehicle according to the aforementioned sub-vehicle identification signal.

According to the articulated vehicle connection identification system of the implementation method described in the previous paragraph, when the articulated vehicle is connected to a connected sub-vehicle, the signal identification module can be electrically connected to the identification signal sending module of the aforementioned connected sub-vehicle in a wired manner.

According to the articulated vehicle connection identification system of the embodiment described in the previous paragraph, the articulated vehicle may further include a power supply unit, which is arranged on the main body of the articulated vehicle. When the articulated vehicle is connected to a connected sub-vehicle, the power supply unit is electrically connected to the identification signal sending module of the aforementioned connected sub-vehicle to provide power, and the identification signal sending module of the aforementioned connected sub-vehicle sends a sub-vehicle identification signal in a wireless signal mode after being powered on.

According to the above-mentioned embodiment of the articulated vehicle connection identification system, each identification signal sending module can send each sub-vehicle identification signal in a wireless signal mode, and the signal identification module can include a receiving antenna. The receiving antenna is used to receive each sub-vehicle identification signal.

According to the articulated vehicle connection identification system of the implementation method described in the previous paragraph, the signal identification module can update a received sub-vehicle identification signal at a preset time interval, and when the number of times the same sub-vehicle identification signal is continuously received is greater than or equal to a preset number of times, the signal identification module determines that the connected sub-vehicle corresponding to the aforementioned sub-vehicle identification signal is connected to the articulated vehicle.

According to one embodiment of the present invention, a method for identifying a vehicle connection is provided, which includes a sub-vehicle connection step, a sub-vehicle signal receiving step, and a sub-vehicle identification step. In the sub-vehicle connection step, a connected sub-vehicle among a plurality of connected sub-vehicles is connected to an articulated vehicle, and each connected sub-vehicle includes an identification signal sending module. In the sub-vehicle signal receiving step, each identification signal sending module is used to send a sub-vehicle identification signal so that a signal identification module of the articulated vehicle receives a sub-vehicle identification signal. In the sub-vehicle identification step, the signal identification module determines the identification code of the connected sub-vehicle connected to the articulated vehicle according to the aforementioned sub-vehicle identification signal.

According to the articulated vehicle connection identification method of the above-mentioned implementation mode, in the sub-vehicle signal receiving step, the sub-vehicle identification signal can be sent to the signal identification module of the articulated vehicle through a signal line.

According to the articulated vehicle connection identification method of the embodiment described in the previous paragraph, in the sub-vehicle connection step, a power supply unit of the articulated vehicle can be electrically connected to the identification signal sending module of the connected sub-vehicle and provide power to the identification signal sending module of the connected sub-vehicle.

According to the articulated vehicle connection identification method of the implementation method described in the previous paragraph, in the sub-vehicle signal sending step, the sub-vehicle identification signal can be sent to the signal recognition module of the articulated vehicle in a wireless signal manner.

According to the articulated vehicle connection identification method of the implementation method described in the previous paragraph, in the sub-vehicle identification step, the signal recognition module can update a received sub-vehicle identification signal every preset time, and when the number of times the same sub-vehicle identification signal is continuously received is greater than or equal to a preset number of times, the signal recognition module determines that a connected sub-vehicle corresponding to the aforementioned sub-vehicle identification signal is connected to the articulated vehicle, and transmits a sub-vehicle correction vehicle code signal to a monitoring system.

Please refer to FIG. 1, which shows a schematic diagram of an articulated vehicle connection identification system 100 according to the first embodiment of the present disclosure. As shown in FIG. 1, the articulated vehicle connection identification system 100 includes an articulated vehicle 110 and a plurality of articulated sub-vehicles 120 and 130 (only two articulated sub-vehicles 120 and 130 are shown in FIG. 1, but the present disclosure is not limited thereto). The articulated vehicle 110 includes an articulated vehicle body 111, a plurality of articulated vehicle wheels 112, and a signal identification module 113. The articulated vehicle wheels 112 and the signal identification module 113 are both disposed on the articulated vehicle body 111. In the present disclosure, the coupling sub-vehicle 120 is taken as an example, which includes a sub-vehicle body 121, a plurality of sub-vehicle wheels 122 and an identification signal sending module 123. The sub-vehicle body 121 is used to detachably connect to the coupling vehicle 110. The sub-vehicle wheels 122 are arranged on the sub-vehicle body 121. The identification signal sending module 123 is arranged on the sub-vehicle body 121 and is used to send a sub-vehicle identification signal to the signal identification module 113. The coupling sub-vehicle 130 and other unillustrated coupling sub-vehicles are the same as the coupling sub-vehicle 120. Among them, when the signal identification module 113 receives a sub-vehicle identification signal, the signal identification module 113 determines the identification code of a coupling sub-vehicle 120 connected to the coupling vehicle 110 according to the aforementioned sub-vehicle identification signal. The identification signal sending module 123 sends the sub-vehicle identification signal to the signal identification module 113 of the articulated vehicle 110. The signal identification module 113 can determine that the sub-vehicle connected to the articulated vehicle 110 is the articulated vehicle 120 according to the sub-vehicle identification signal, thereby helping the user to confirm the identification code of the currently connected sub-vehicle 120, thereby preventing the user from connecting to an articulated vehicle that is not the default connection when driving the articulated vehicle 110, thereby reducing the possibility of human error. The details of the articulated vehicle connection identification system 100 will be described in detail below.

Specifically, the signal identification module 113 may include a receiving antenna 1131 and a processor 1132, and each connected sub-vehicle 120, 130 sends each sub-vehicle identification signal in a wireless signal mode. The receiving antenna 1131 is used to receive each sub-vehicle identification signal. The processor 1132 is signal-connected to the receiving antenna 1131, and determines the identification code of the connected sub-vehicle 120 connected to the connected vehicle 110 according to the sub-vehicle identification signal received by the receiving antenna 1131. Furthermore, the processor 1132 can further display the identification code of the connected sub-vehicle 120 on a display screen of the connected vehicle 110, or transmit it to a monitoring device, so that the user can confirm the current connection status of the connected vehicle 110.

As shown in FIG. 1 , the articulated vehicle 110 may further include a power supply unit 114. The power supply unit 114 is disposed on the articulated vehicle body 111. When the articulated vehicle 110 is connected to an articulated sub-vehicle 120, the power supply unit 114 is electrically connected to the identification signal transmission module 123 of the articulated sub-vehicle 120 to provide power, and the identification signal transmission module 123 of the articulated sub-vehicle 120 transmits the sub-vehicle identification signal in a wireless signal manner after being powered on. In other words, when the articulated vehicle 110 is connected to the articulated sub-vehicle 120, the articulated vehicle 110 activates the identification signal transmission module 123 through the power supply unit 114. Specifically, when the articulated vehicle 110 is connected to the connected sub-vehicle 120, the connection is performed through a connection device, and the connection device includes a plurality of pipelines, wherein the power supply unit 114 can be electrically connected to the identification signal transmission module 123 through a cable disposed in the pipeline of the connection device, but the present disclosure is not limited thereto. Furthermore, when the identification signal transmission module 123 is activated due to power supply, the sub-vehicle identification signal is sent to the receiving antenna 1131, so that the processor 1132 determines the identification code of the connected sub-vehicle 120 according to the sub-vehicle identification signal, thereby preventing the receiving antenna 1131 from receiving the sub-vehicle identification signal of the connected sub-vehicle 130 that sends the sub-vehicle identification signal in the form of a wireless signal. Therefore, although the sub-vehicle identification signal of the articulated vehicle 120 is sent in a wireless signal mode, the probability of the signal identification module 113 of the articulated vehicle 110 misjudging that the articulated vehicle 110 is connected to other adjacent articulated vehicles 130 can still be reduced. In other words, when other articulated vehicles (such as the articulated vehicle 130) are in a stationary state, or are connected to other articulated vehicles that are not powered on and started, the identification signal sending module of the aforementioned other articulated vehicles will not send a sub-vehicle identification signal, so that the signal identification module 113 of the adjacent articulated vehicle 110 will not misjudge. In this way, the possibility of the signal identification module 113 receiving an erroneous sub-vehicle identification signal can be reduced.

Please refer to FIG. 2, which shows a schematic diagram of an articulated vehicle connection identification system 200 according to a second embodiment of the present disclosure. As shown in FIG. 2, the articulated vehicle connection identification system 200 includes an articulated vehicle 210 and a plurality of articulated sub-vehicles 220 and 230. The articulated vehicle 210 includes an articulated vehicle body 211, a plurality of articulated vehicle wheels 212, and a signal identification module 213, and the articulated vehicle wheels 212 and the signal identification module 213 are disposed on the articulated vehicle body 211. The structure and configuration of the articulated sub-vehicles 220 and 230 of the second embodiment are the same as the structure and configuration of the articulated sub-vehicles 120 and 130 of the first embodiment, and are not described in detail here.

Specifically, when the articulated vehicle 210 is connected to a connected sub-vehicle (in FIG. 2 , the connected sub-vehicle is the articulated sub-vehicle 220), the signal recognition module 213 of the articulated vehicle 210 is electrically connected to the identification signal transmission module 223 of the connected sub-vehicle 220 in a wired manner. Specifically, the identification signal transmission module 223 is disposed on the sub-vehicle body 221 and is located at one end of the remote vehicle wheel 222. The signal recognition module 213 can be electrically connected to the identification signal transmission module 223 via a signal line. By using a physical wired method, the problem of misjudgment caused by the signal recognition module 213 receiving the identification code of the connected sub-vehicle transmitted by the wireless signal of the neighboring connected sub-vehicle can be improved. Thereby, the sub-vehicle identification signal connected to the sub-vehicle 220 can be sent to the signal recognition module 213 in the form of an electronic signal, thereby improving the stability and accuracy of the determination of the signal recognition module 213.

Please refer to FIG. 3, which shows a schematic diagram of an articulated vehicle connection identification system 300 according to a third embodiment of the present disclosure. As shown in FIG. 3, the articulated vehicle connection identification system 300 includes an articulated vehicle 310 and a plurality of articulated sub-vehicles 320 and 330. The articulated vehicle 310 includes an articulated vehicle body 311, a plurality of articulated vehicle wheels 312, and a signal identification module 313, and the articulated vehicle wheels 312 and the signal identification module 313 are disposed on the articulated vehicle body 311. Taking the connected sub-vehicle 320 as an example, the connected sub-vehicle 320 includes a sub-vehicle body 321, sub-vehicle wheels 322 and an identification signal sending module 323, and the structure and configuration of the connected sub-vehicles 320 and 330 of the third embodiment are the same as the structure and configuration of the connected sub-vehicles 120 and 130 of the first embodiment, which will not be repeated here.

In particular, in the third embodiment, the signal recognition module 313 may include a receiving antenna 3131 and a processor 3132, and the identification signal sending modules 323, 333 of each connected sub-car 320, 330 send the sub-car identification signal in a wireless signal mode. The receiving antenna 3131 is used to receive each sub-car identification signal of each connected sub-car 320, 330, and the processor 3132 is signal-connected to the receiving antenna 3131, and determines the identification code of the connected sub-car 320 connected to the connected car 310 according to the sub-car identification signal received by the receiving antenna 3131. Specifically, the identification signal sending modules 323 and 333 can continuously send the sub-vehicle identification signal to the receiving antenna 3131, and the receiving antenna 3131 regards the sub-vehicle identification signal received earliest as the sub-vehicle identification signal of the connected vehicle 310. In this way, the configuration flexibility of the identification signal sending modules 323 and 333 can be improved, and the cost of wired connection can be reduced.

Furthermore, in the third embodiment, the signal recognition module 313 may update the received sub-vehicle identification signal at a preset time interval, and when the number of times the same sub-vehicle identification signal is continuously received is greater than or equal to a preset number of times, the signal recognition module 313 determines that a coupled sub-vehicle 320 corresponding to the aforementioned sub-vehicle identification signal is connected to the articulated vehicle 310. When there are a plurality of coupled sub-vehicles 320 and 330 at the parking place of the articulated vehicle 310, the sub-vehicle identification signal received by the signal recognition module 313 may not be the sub-vehicle identification signal of the coupled sub-vehicle 320 connected to the articulated vehicle 310 due to the parking positions of the coupled sub-vehicles 320 and 330. However, when the articulated vehicle 310 is connected to the connected sub-vehicle 320 and is driving in parallel, the signal recognition module 313 can continuously update the received sub-vehicle identification signal, and at this time, it will not receive the sub-vehicle identification signal of other connected sub-vehicles 330. Therefore, by continuously receiving and updating the sub-vehicle identification signal through the signal recognition module 313, the stability of the sub-vehicle identification signal determined by the signal recognition module 313 can be improved to avoid the possibility of misjudgment due to wireless signals. Specifically, when the articulated vehicle 310 is parked in the parking lot, the signal recognition module 313 of the articulated vehicle 310 mistakenly determines that the signal is a sub-vehicle identification signal of the articulated sub-vehicle 330 that is not actually connected to the articulated vehicle 310. After the articulated vehicle 310 tows the actually connected articulated sub-vehicle 320 out of the parking lot and drives on the road, the received sub-vehicle identification signal can be updated at a preset time to cover the erroneous sub-vehicle identification signal.

Please refer to FIG. 4, which shows a step block diagram of an articulated vehicle connection identification method S100 according to a fourth embodiment of the present disclosure. The articulated vehicle connection identification method S100 will be described in conjunction with the articulated vehicle connection identification system 300 of the third embodiment, but the present disclosure is not limited thereto. As shown in FIG. 4, the articulated vehicle connection identification method S100 includes a sub-vehicle connection step S110, a sub-vehicle signal receiving step S120, and a sub-vehicle identification step S130. In the sub-vehicle connection step S110, a connected sub-vehicle 320 of a plurality of connected sub-vehicles 320, 330 is connected to an articulated vehicle 310, and each of the connected sub-vehicles 320, 330 includes an identification signal sending module 323, 333. In the vehicle signal receiving step S120, each identification signal sending module 323, 333 is used to send a vehicle identification signal, so that a signal identification module 313 of the articulated vehicle 310 receives a vehicle identification signal. In the vehicle identification step S130, the signal identification module 313 determines the identification code of the articulated vehicle 320 connected to the articulated vehicle 310 according to the vehicle identification signal. By receiving the sub-vehicle identification signal from the connected sub-vehicles 320 and 330 through the articulated vehicle 310, the signal recognition module 313 of the articulated vehicle 310 can determine the articulated sub-vehicle 320 currently connected to the articulated vehicle 310, so that the user can confirm the identification code of the currently connected articulated sub-vehicle 320, thereby preventing the user from connecting to an articulated sub-vehicle that is not the default connection and reducing the possibility of human error.

Please refer to FIG. 5, which shows a flow chart of the steps of the articulated vehicle connection identification method S100 according to the fourth embodiment of FIG. 4. As shown in FIG. 5, the articulated vehicle connection identification method S100 includes steps S210, S220, S230, S240, and S250. In step S210, the articulated vehicle 310 is connected to a connected sub-vehicle 320, and step S220 is executed. In step S220, each identification signal sending module 323, 333 sends a sub-vehicle identification signal in a wireless signal mode, and step S230 is executed. Through the configuration of step S220, the speed of the articulated vehicle 310 can be increased. It should be noted that the execution order of steps S210 and S220 can be performed simultaneously or sequentially, and the present disclosure is not limited thereto. In step S230, the signal recognition module 313 receives the sub-vehicle identification signal of one of the identification signal sending modules 323 and 333, and determines the identification code of a connected sub-vehicle 320 connected to the articulated vehicle 310 according to the aforementioned sub-vehicle identification signal, and executes step S240. In step S240, the signal recognition module 313 updates the received sub-vehicle identification signal every preset time, and executes step S250. In step S250, when the number of times the same sub-vehicle identification signal is continuously received is greater than or equal to a preset number of times, the signal recognition module 313 determines that a connected sub-vehicle 320 corresponding to the aforementioned sub-vehicle identification signal is connected to the connected vehicle 310, and transmits a sub-vehicle correction vehicle code signal to a monitoring system according to the aforementioned sub-vehicle identification signal. Through steps S240 and S250, the advantage of sending the sub-vehicle identification signal in a wireless signal mode in step S220 can be retained, and the probability of misjudgment can be further reduced. When the articulated vehicle 310 is parked in the parking lot, if the signal recognition module 313 of the articulated vehicle 310 mistakenly judges the sub-vehicle identification signal of the articulated sub-vehicle 330 that is not actually connected to the articulated vehicle 310, after the articulated vehicle 310 tows the actually connected articulated sub-vehicle 320 out of the parking lot and drives on the road, the received sub-vehicle identification signal can be updated at a preset time to cover the erroneous sub-vehicle identification signal.

In other embodiments, in the sub-vehicle signal receiving step, the sub-vehicle identification signal can be sent to the signal identification module of the connected vehicle through a signal line. The physical wired connection method can improve the problem that the signal identification module may make a misjudgment due to receiving the identification code of the connected sub-vehicle transmitted by the wireless signal of the adjacent connected sub-vehicle. In this way, the accuracy of the signal identification module in determining the sub-vehicle identification signal can be improved.

In other embodiments, in the sub-vehicle connection step, a power supply unit of the articulated vehicle can be electrically connected to an identification signal sending module of a connected sub-vehicle, and provide power to the identification signal sending module of the connected sub-vehicle. Thereby, although the sub-vehicle identification signal of the connected sub-vehicle is sent in the form of a wireless signal, the probability of the articulated vehicle signal identification module misjudging that the articulated vehicle is connected to other adjacent articulated sub-vehicles can still be reduced. Furthermore, when other articulated sub-vehicles are in a static state, or are connected to other articulated vehicles that are not powered on and started, the identification signal sending modules of the aforementioned other articulated sub-vehicles will not send identification signals, so that the signal identification modules of adjacent articulated vehicles will not be misjudged.

In summary, the present invention has the following advantages: first, through the configuration of the signal recognition module and the identification signal transmission module, it is convenient for the user to confirm the identification code of the connected sub-vehicle, thereby avoiding the possibility of human error; second, by connecting the signal recognition module to the identification signal transmission module in a wired manner, the stability of the signal recognition module receiving the sub-vehicle identification signal can be improved; and, third, by updating the sub-vehicle identification signal at a preset time by the signal recognition module, it can be ensured whether the signal recognition module correctly receives the sub-vehicle identification signal.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
