摘要： PROBLEM TO BE SOLVED: To enhance the performance and the reliability of a wireless network by stably transferring data in the wireless network whose channel quality changes every moment. SOLUTION: In the wireless network adopting a logical configuration where transfer paths are in existence among a plurality of wireless communication controllers in the case of transferring data from an optical sender to an optical destination, a control section 200 of a wireless communication controller being the sender transmits a path investigation frame to paths leading to the destination prior to start of transmission and discriminates paths such as those received earlier by the destination, paths with less retrial number of times or paths with a small channel load to decide the path to be used for the transmission. The wireless communication controllers acting like relay stations in each path obtain number of retrial times/channel load of its own and apply update processing to the path investigation frame and store the result. Moreover, the wireless communication controller acting like the destination acquires path information (retrial times/channel load) on the way by data frames during communication, detects a fault when a value of the path information received by the destination exceeds a value stored in a threshold value storage section 211, and informs the sender about the occurrence of the fault in the path in use to allow the sender to select other path.

摘要： PROBLEM TO BE SOLVED: To avoid missing in reception caused by difference from a clock frequency between nodes connecting to a network in the network system adopting an SLDCGA polling system where a plurality of nodes are connected via a common loop network. SOLUTION: A transmission controller 11 of each node is provided with a means 61 that extracts a signal clock received from an upperstream node, a means 53 that generates a clock unique to each node, a means 52 that discriminates whether or not the signal received from the upperstream node is data, and a means 51 that selects a clock to send a signal to a downstream node, in the case that the signal received from the upperstream node is data and data to be sent are in existence in its own node, the clock generated uniquely to its own node is used to send a signal to the downstream node, and in the case that the signal received from the upperstream node is not data but an idle signal, the clock signal of the signal received from the upperstream node is used as it is and the signal is sent to the downstream node.

摘要： PROBLEM TO BE SOLVED: To shorten a cycle period by limiting a station capable of transmitting a message per logical ring of a token and reducing maximum token cycle time. SOLUTION: At the time of receiving a message transmission request signal S14 from an MPU 504, a transmission control circuit 503 generates a transmission frame from a destination transmission station address and message data stored in a dual port memory 507 and waits for a transmission right to be transferred from a preceding station on the logical ring. The MPU 504 informs the transmission control circuit 503 of the address of an area where the destination station address and the message data are written in the dual port memory beforehand. The transmission control circuit 503 outputs a count-up signal S2 at the time of acquiring the transmission right and transmits a message data frame through a transmission modem 514, a branching cable 2 and a common transmission line 14 to a destination station at the time of receiving a message transmission permission signal S15 for the output.

摘要： PURPOSE:To prevent the reduction in transmission efficiency by using a time slot being one multiplex unit in a loop transmission line in common for the connection of plural stations accommodated in the loop transmission line. CONSTITUTION:Effective channels in local multiplex information in plural stations ST connected to a network comprising loop transmission lines are linked. Thus, the time slot on the loop transmission line used to send the information between a center side station CST 205 and plural local stations DST 204 is limited to one and the information transmission efficiency on the loop transmission line is improved more than the case with the assignment of one time slot on the loop transmission line onto multiplex information of each local side station DST.
