[0085] A second embodiment will be described. In this embodiment, the same reference numerals are assigned to the same configurations as those in the above-mentioned embodiment, and descriptions thereof are omitted or simplified. Figure 7 It is a figure which shows the operation|movement of the traveling vehicle system of this embodiment. For each part of the host control device 4 and each part of the traveling vehicle 3, refer to figure 2 Wait. exist Figure 7 In (A), the traveling vehicle 3d (third traveling vehicle) is a traveling vehicle that runs ahead on the same route as the traveling vehicle 3c. Such as Figure 7 As shown in (B), when each traveling vehicle 3 was advancing, the traveling vehicle 3d sent a passing permission request for the junction 7 to the upper control device 4 (refer to figure 2 )send. When the communication unit 25 of the host control device 4 grasps that the passing permission request for the merging part 7 has been received from the trav...

Abstract

The present invention enables the vehicle ahead of the priority vehicle to pass through the intersection smoothly through simple control, thereby ensuring the priority travel of the priority vehicle. The driving vehicle system (1A) has: a plurality of driving vehicles (3); (3a) the first traveling vehicle (3b) of the branch part (6) that is scheduled to pass through, the junction part (7) that the first traveling vehicle (3b) is scheduled to pass through after the branching part (6) is derived by the junction part deriving part (29) ), the passing permission of the merging part (7) is sent to the first driving vehicle (3b) with priority over the second driving vehicle (3c), which is different from the first driving vehicle (3b) The direction is intended to pass through the junction (7).

Description

technical field [0001] The invention relates to a traveling vehicle system and a control method of the traveling vehicle system. Background technique [0002] In semiconductor device manufacturing plants and the like, goods containing, for example, semiconductor wafers or reticles are conveyed by a traveling vehicle system. This traveling vehicle system includes a plurality of traveling vehicles traveling on a rail and a controller (for example, a higher-level control device) for controlling the plurality of traveling vehicles. Each of the plurality of traveling vehicles transmits the current position and the like of the own device to the controller through wireless communication or the like. The controller determines a traveling vehicle in charge of transporting the cargo based on the position of the traveling vehicle, etc., and sends a driving command to the traveling vehicle. [0003] The rails of the traveling vehicle system as described above generally have intersecti...
