Description

  The present invention is applied to a garbage incineration facility or the like, and relates to a vehicle control device that guides a vehicle entering a platform to any gate.

  In a garbage incineration facility, etc., a vehicle for carrying waste that has entered on a dedicated platform from the entrance of the vehicle is guided to one of a plurality of gates arranged in parallel with each other, and a predetermined amount of waste is thrown in at the guided gate. Have work done. After completion of the work, the vehicle exits from the exit through the exit located on the opposite side of the entrance. In this case, guidance to the gate of the garbage carrying vehicle is selected in order for a plurality of gates (garbage bunker doors), and guidance instructions are given.

  That is, as shown in FIG. 6, the platform 11 of the waste incineration facility is provided with an entrance 12 and an exit 13 at both left and right ends, and a plurality of gates (trash bunker doors) along one side of the platform 11. 14 are juxtaposed. Numbers “1”, “2”,..., “N−1”, “n” are sequentially set in each gate 14 from the exit 13 side toward the entrance 12 side. As shown in FIG. 7, the vehicle that has entered the platform 11 from the entrance 12 is guided to the gate 14 of the number selected cyclically from the youngest number. Vehicles for which processing such as throwing in garbage is completed at the guided gate 14 exit from the exit 11 to the outside of the platform 11.

  In such control control for vehicles, generally, the collection time zone of garbage is concentrated in a specific time zone of the day, so the time zone of carrying in to the garbage incinerator is also concentrated. For this reason, the platform is also in rush hour. As described above, in the time zone in which garbage carrying vehicles are concentrated, the number of vehicles staying in the platform 11 increases. If these vehicles are shifted to the approach and exit roads, a vehicle traffic jam occurs, and in the worst case, a collision accident may occur.

  As described above, the guidance of the vehicle on the platform 11 selects the destination gate in order from the young door number and instructs the loading vehicle. For this reason, when the door number selected last time is on the approach road side, the gate of the next number is mechanically instructed, so the entry side is instructed even though the exit side is vacant. For this reason, when the platform 11 is congested to some extent, it becomes a cause of congestion and congestion on the approach road. Further, even if the previously selected door is on the exit side, if the number of vehicles carried in exceeds a certain number, there will be a traffic jam on the exit side.

For such problems, it has been proposed to guide the vehicle efficiently by capturing and displaying the state of the vehicle at each gate with a television camera or the like, or capturing the position of each vehicle with a GPS system. (For example, refer to Patent Document 1).
JP 2004-131225 A

  However, using the above-described television camera and GPS system is not practical because the equipment cost is greatly increased.

  Here, when the trend of vehicles on the platform was verified, even if the number of garbage trucks staying there is large, it can lead to the elimination of traffic jams by guiding the vehicles so that the vehicles do not deviate to the entry / exit areas. It was found.

  An object of the present invention is to provide a vehicle control device that enables smooth vehicle control without causing traffic congestion by quickly guiding vehicles entering the platform to the optimal gate even when the number of vehicles staying on the platform increases. There is to do.

  The vehicle control device of the present invention is a platform in which an entrance of a vehicle is provided on one side, an exit is provided on the other side, and a plurality of gates are provided in parallel between them. A vehicle control device for guiding a vehicle entering the foam to any one of the gates, and a staying number detecting means for detecting the number of staying vehicles on the platform, and to which gate the vehicle entering the platform is guided The guidance gate storage means for storing information and the platform are divided into an exit area including a predetermined number of gates from the exit and an entrance area on the entrance side including the remaining gates. An area determination means for determining whether the gate to which the vehicle is guided is the exit area or the entry area, and the vehicle platform each time the vehicle enters the platform. The congestion level of the vehicle is determined based on the number of vehicles staying in the vehicle, and if the congestion level is higher than the set level, the vehicle that has entered this time is vacant near the exit in areas other than the area that was previously guided. Vehicle guidance means for guiding to a gate and guiding to an empty gate next to the previously guided gate if the degree of congestion is not during the congestion is provided.

  The vehicle control device according to the present invention includes a staying number detecting means for detecting the number of staying vehicles on the platform, and a guide gate storing means for storing to which gate the vehicle that has entered the platform is guided. Each time a vehicle enters the platform, the degree of congestion of the vehicle is determined based on the number of staying vehicles on the vehicle platform. On the other hand, it is also possible to provide a vehicle guidance means for guiding to a vacant gate skipped over a plurality of preset gates and guiding the vacant gate next to the previously guided gate if the degree of congestion is not during the congestion. Good.

  According to the present invention, when the number of vehicles staying in the platform exceeds a certain level, the vehicle is guided to the gates at positions dispersed with respect to the previously guided gate. It is possible to control the vehicle smoothly by preventing traffic congestion from occurring in the area on the side.

  Hereinafter, an embodiment of a vehicle control device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a functional block diagram showing the configuration of the vehicle control device according to this embodiment. As shown in FIG. 6, the vehicle control apparatus according to this embodiment also includes a plurality of gates (a plurality of gates (which are arranged in parallel along one side of the platform 11), which are vehicles that have entered the platform 11 of the garbage incineration facility through the entrance 12. It will guide you to one of the garbage bunker doors) 14. In addition, the vehicles for which processing such as throwing in the garbage is completed at the guided gate 14 exit from the exit 13 to the outside of the platform 11, respectively. In addition, numbers “1”, “2”,..., “N−1” and “n” are sequentially set in each gate 14 from the exit 13 side toward the entrance 12 side.

  In FIG. 1, a vehicle entry detector 21 is provided at the entrance 12 shown in FIG. 6 and detects a vehicle entering the platform 11. A vehicle exit detector 22 is provided in the exit 13 shown in FIG. 6 and detects a vehicle exiting the platform 11.

  Reference numeral 23 denotes a staying number detecting means for detecting the number of staying vehicles on the platform 11 from the number of entering and leaving of the platform 11 obtained from the entry detector 21 and the leaving detector 22. Reference numeral 24 denotes guide gate storage means for storing which gate 14 a vehicle that has entered the platform 11 is guided by the vehicle guide means 25 described later. 26 is an area determination means, and the platform 11 is connected to the exit 12 side including the exit area including a predetermined number of gates 14 from the exit 13 (for example, half of the total gate number a: a / 2) and the remaining gates 14. It is divided and stored in the entry area. Then, it is determined whether the gate 14 to which the previous vehicle was guided belongs to either the exit area or the entry area.

  The vehicle guidance means 25 has a congestion degree determination function 25a and a guidance gate determination function 25b. The congestion degree determination function 25a operates according to the detection signal from the entry detector 21 every time the vehicle enters the platform 11, and based on the staying number detected by the staying number detecting means 23, the following expression (1) The degree of congestion of the vehicle on the platform 11 is determined based on the determination criteria shown in FIG.

a / m <2 * c (1)
a: Total number of gates m: Predetermined congestion coefficient c: Number of stays The congestion degree determination function 25a determines that the determination criterion of the above expression (1) is satisfied (when the congestion degree is equal to or higher than a set level). Is determined. If the congestion degree is “congested”, the guidance gate determination function 25b vacates the vehicle that has entered this time closest to the exit 13 in an area other than the previously guided area based on the information from the area determination means 26. Guide to the gate. For example, if the previously guided area is the entry area, the gate closest to the exit 13 in the other exit areas (the gate with the number “1”) 14 is selected and guided to. If it is the exit area, the gate 14 (number “a / 2 + 1”) closest to the exit 13 in the other entry area is selected and guided to.

  On the other hand, if the degree of congestion is not “congested”, guidance is made to an empty gate next to the previously guided gate by normal cyclic selection.

  Next, the operation will be described with reference to the flowcharts of FIGS. When the entry of the vehicle into the platform 11 is detected by the entrance detector 21 at the entrance 12 portion, the process starts, and as shown in FIG. 2, it is determined to which area the gate 14 previously guided belongs (step). 201, 202). That is, if the gate number b to which the previous vehicle was guided is larger than half of the total gate number a, the previous guidance area is determined as the “entrance area”.

  Next, the degree of congestion is detected from the number of vehicles staying on the current platform 11 using the equation (1) (steps 203 and 204). That is, if the staying number c is larger than 1 / m of the total number a of the gates 14, the platform determines that “congested”.

  As a result, if the previous guidance area is the entry area (step 202: Y) and the platform 11 is “crowded” (step 204: Y), the gate with the gate number “b + 1” is not indicated, “ “NO.1” gate (the gate closest to the exit 13 in the exit area other than the entrance area) is instructed again (step 205).

  On the other hand, when the previous guidance area is not the entry area (step 202: N) or when the platform 11 is not “crowded” (step 204: N), the gate that was previously guided by the normal cyclic selection is used. Guide to the empty gate next to (step 206).

  As shown in FIG. 3, when the gate number b of the gate 14 guided last time is smaller than half of the total gate number a, it is determined that the previous guidance area is “exit area” (step 302).

  Next, when the number of stays c on the current platform 11 is larger than 1 / m of the total number a of the gates 14 (step 303), it is determined that the platform 11 is “crowded” (step 304: Y).

  As a result, if the previous guidance area is the exit area (step 302: Y) and the platform 11 is “crowded” (step 304: Y), the gate of the gate number “b + 1” is not instructed and “ "NO. (A / 2; 1)" The gate (the gate closest to the exit 13 in the entry area other than the exit area) is designated again (step 305).

  On the other hand, if the previous guidance area is not the exit area (step 302: N), or if the platform 11 is not “crowded” (step 304: N), the gate guided last time by the normal cyclic selection Guide to the empty gate next to (step 306).

  In this way, when the platform 11 is congested to some extent, the vehicle is guided to an empty gate in the other area other than the area to which the gate 14 previously guided belongs, so as in the conventional case where the gate is simply selected cyclically, The vehicle does not move to the area on the entry side or the exit side, and traffic congestion can be prevented and smooth vehicle control becomes possible.

  Next, the embodiment shown in FIGS. 4 and 5 will be described. In this embodiment, when the platform 11 is congested to some extent without considering the area to which the previously guided gate belongs, the skipped gate is selected and guided for a plurality of preset gates with respect to the previously guided gate. Like to do.

  In FIG. 4, the vehicle entrance detector 21, exit detector 22, staying number detection means 23 and guide gate storage means 24 are the same as those shown in FIG. 1. However, the area determination means 26 in FIG. 1 is not used. For this reason, in the vehicle guidance means 35, although the congestion determination function 35a is common to FIG. 1, the guidance gate determination function 35b is different from FIG.

  That is, as will be described with reference to the flowchart of FIG. 5, the process starts when the entry of the vehicle into the platform 11 is detected by the entry detector 21 in the entrance 12 portion. The congestion level is detected using the equation (1) (step 501). When the staying number c is larger than 1 / m of the total number a of the gates 14, it is determined that the platform is “crowded” (step 502).

  Thus, if the platform 11 is “crowded” (step 502: Y), the skipped gate is selected for a plurality of preset gates without designating the gate of the gate number “b + 1” (step 503). . In the example shown in the figure, a gate with a skipped gate number: “NO. (B + 2)” for two gates set in advance is indicated.

  On the other hand, when the platform 11 is not “crowded” (step 502: N), the platform 11 is guided to an empty gate next to the previously guided gate by normal cyclic selection (step 504).

  In this way, when the platform 11 is congested to some extent, the skipped gate is selected and guided to the gate 14 that was previously guided for a plurality of preset gates. Therefore, smooth traffic control is possible by preventing traffic jams.

  In any of the above embodiments, the staying number detecting means 23 detects the staying number on the platform 11 from the number of entering and leaving of the vehicle obtained from the approach detector 21 and the exit detector 22. However, the present invention is not limited to such a method, and various types of methods such as detecting the number of stays from an image on the platform may be applied.
