Management equipment and information processing systems

Abstract

To continue data collection from measuring instruments when a repeater fails.SOLUTION: In an information processing system 100, a management apparatus 50 collecting measurement data transmitted from a plurality of measuring instruments 60 through a plurality of repeaters 40 comprises: a connection monitoring unit that monitors the state of connection between the management apparatus 50 and the repeaters 40; and a substitute connection request unit that, when there is one repeater 40 in which the state of connection with the management apparatus 50 is a disconnection state, requests connection to another repeater 40 that collects data in place of the disconnected repeater.SELECTED DRAWING: Figure 9

Claims

1. In a management device that collects measurement data transmitted from multiple measuring instruments via multiple relay devices, A connection monitoring unit that monitors the connection status between the management device and the relay device, If the connection monitoring unit determines that a relay device has lost its connection to the management device, and therefore determines that a relay device has malfunctioned, the proxy connection request unit requests a connection to another relay device that will take over data collection. Equipped with, The proxy connection request unit acquires the location information of the measuring instrument to which the first relay unit was connected, and selects the other relay unit that minimizes the distance calculated from the location information of the other relay unit and the measuring instrument to which the first relay unit that failed was connected as the other relay unit to take over data collection. A management device characterized by the following features.

2. The connection monitoring unit determines that the connection between the management device and the relay device has been disconnected based on the fact that no measurement data is transmitted from the relay device for a certain period of time. The control device according to feature 1.

3. The system includes a distance measurement request unit that requests distance measurement from the relay unit, which is capable of measuring distance based on the received radio wave strength in short-range wireless communication, and acquires distance information between the other relay unit and the measuring instrument to which the faulty relay unit was connected when determining which relay unit will take over data collection. The control device according to feature 1.

4. Each of the aforementioned measuring instruments employs a communication method that connects to the relay device in a many-to-one manner. The control device according to feature 1.

5. In an information processing system that collects measurement data transmitted from multiple measuring instruments via multiple relay devices into a management device, The aforementioned management equipment is A connection monitoring unit that monitors the connection status between the management device and the relay device, If the connection monitoring unit determines that a relay device has lost its connection to the management device, and therefore determines that a relay device has malfunctioned, the proxy connection request unit requests a connection to another relay device that will take over data collection. Equipped with, The proxy connection request unit acquires the location information of the measuring instrument to which the first relay unit was connected, and selects the other relay unit that minimizes the distance calculated from the location information of the other relay unit and the measuring instrument to which the first relay unit that failed was connected as the other relay unit to take over data collection. The aforementioned relay device is The system includes a measuring instrument connection unit that, upon receiving a connection request from a measuring instrument to which a relay unit that has malfunctioned due to a disconnection from the management device was connected has been disconnected, initiates a connection to the said measuring instrument. An information processing system characterized by the following:
