A base wireless device includes a selection unit configured to select either signal transmission or standby, and a transmission processing unit configured to perform a transmission process of transmitting a signal to at least one remote wireless device in a case that the selection unit selects the signal transmission, and to stand by without performing the transmission process in a case that the selection unit selects the standby. The selection unit selects either the signal transmission or the standby in a current transmission/reception period in accordance with a predetermined rule in a case that the signal transmission was selected in a previous transmission/reception period, and selects the signal transmission in the current transmission/reception period in a case that the standby was selected in the previous transmission/reception period.

Base wireless device and communication method of base wireless device

In an industrial wireless communication system. a base wireless device has a synchronous connection transmission unit for broadcasting a synchronous connection signal to achieve synchronous connection to a remote wireless device in only a single synchronous connection period which is an integral multiple of a hopping period. The synchronous connection transmission unit sequentially switches communication frequencies for synchronization so as to transmit the synchronous connection signal with a plurality of communication frequencies for synchronization within one hopping period. A synchronous connection reception unit sequentially switches communication frequencies for synchronization with a switching period which is longer than the hopping period and shorter than twice the hopping period, so as to perform a reception wait process for the synchronous connection signal with a plurality of communication frequencies for synchronization.

Industrial wireless communication system

A wireless valve manifold is capable of wireless communication, and includes a plurality of solenoid valves. This wireless valve manifold is able to move by means of a movable unit. In addition, the wireless valve manifold includes a battery which can supply power to the plurality of solenoid valves, and a power-receiving control unit which is connected to the battery and which charges the battery with power by means of wireless power transmission from a feeder station of the wireless valve manifold.

A wireless communication system allows the movement of a carriage or an automated conveyance vehicle to which a plurality of slave wireless device and a plurality of appliances are provided. A master control unit of a master wireless device uses a master communication unit to transmit a cut-off request signal to a slave wireless device deviating from a communication-target region. If a slave communication unit receives the cut-off request signal, a slave control unit of the slave wireless device cuts off a wireless connection.
