Description

Conveying system Technical Field The present specification discloses a handling system. Background Conventionally, a transport control system has been proposed which includes an AGV (Automated Guided Vehicle, automated guided vehicles) that collects and travels an article, and a control server that transmits a control signal to the AGV according to a schedule from a management server (for example, refer to patent document 1). The control server and the AGV have communication interfaces that can communicate with each other via a network. The control server sends control signals for moving the AGV to the destination. The AGV receives a control signal from the control server, controls the driving unit to move to the destination position based on the received control signal, and notifies the control server of completion of the movement to the destination position. Prior art literature Patent literature Patent document 1, japanese patent application laid-open No. 2021-135954. Disclosure of Invention Problems to be solved by the invention In the case where a control instruction is directly transmitted from the server to the automated guided vehicle, the server needs to determine the automated guided vehicle. In a network environment, in order to identify an automated guided vehicle from a server, it is necessary to identify an IP address of the automated guided vehicle, and in particular, when the IP address is dynamically allocated, there is a possibility that the system operation and maintenance performance may be deteriorated due to the management of the IP address. The main object of the present disclosure is to enable a system to be more easily constructed in a transport system in which an automated guided vehicle operates by acquiring instruction information from a host system. Means for solving the problems The present disclosure adopts the following means in order to achieve the above-described main object. The disclosed conveyance system is a conveyance system for conveying an article, and is characterized by comprising: a host system having a host storage unit for storing instruction information related to the transportation of the article, and The automated guided vehicle includes a communication unit capable of communicating via a network, a lower storage unit that stores connection destination information that is a connection destination of the upper storage unit connected to the upper system, and a control unit that controls to confirm instruction information of the upper storage unit by communication using the connection destination information and to operate based on the instruction information. In the network environment, connection destination information of the upper system is uniquely determined. Therefore, the automated guided vehicle confirms the operation command of the host system using the connection destination information, and thus, the automated guided vehicle can be constructed more easily than in the case where the host system determines the IP address of the automated guided vehicle and transmits the operation command.
