摘要： PROBLEM TO BE SOLVED: To provide a technology for optimally determining a control parameter of a signal without overburdening a calculation load of one device.
SOLUTION: This autonomous distributed signal control system has a local station 2 arranged at an intersection 1 existing in a control area 10, and a key intersection determining means. The key local station controls a signal lamp arranged at a key intersection on the basis of a value for minimizing the sum of a prediction value of an average delay at the key intersection and a prediction value of an average delay at an adjacent intersection after determining a plurality of key/adjacent intersection control parameter plans for controlling the key intersection and the adjacent intersection. While, among the local station 2, respective cooperative local stations other than the key intersection control the signal lamp on the basis of a traffic state of one's own intersection while cooperating with a control parameter of the intersection adjacent to the one's own intersection.

摘要： PROBLEM TO BE SOLVED: To accurately calculate the amount of power loss due to the switching operation of a GTO element. SOLUTION: A manufacturing method for inverter equipment involves a process in which the power loss of a GTO element of pnpn structure in switching is evaluated and a process, in which a cooling device is designed. In the power loss evaluating process, gate current is supplied to a gate terminal G of a model circuit for evaluation including a first series circuit in which first p-n junction PN1, a switching means SW, and a second p-n junction PN2 are connected, a second series circuit comprising a resistor R connected in parallel with the switching means SW and a capacitor C, the gate terminal G, and an inductance means L1, and thereafter the switching means is brought into conduction with delay to produce anode current. The gate current is led out of the gate terminal, and further the switching element is brought out of conduction to control the anode current so that the anode current is eliminated. Thus, power loss in the model circuit for evaluation due to switching of the anode current is evaluated.

摘要： PROBLEM TO BE SOLVED: To easily and speedily detect communication abnormality by confirming whether a communication function is recovered or not at every prescribed time, updating the relevant part of table into established state when the recovery is confirmed, and performing communication while alternately using duplexed communication routes. SOLUTION: Each controller 3 transmits the table of communication enable/ disable state to an operator station 1 periodically while using the normal communication route. The operator station 1 displays the table of communication enable/disable state sent from each controller 3 in the table of matrix with a communicating party and presents the part, where the occurrence of any trouble is judged, from the matrix to an operator. Each controller 3 tries communication through the disabled route to the communicating party in disabled state on each route for confirming whether the communication function is recovered or not at every prescribed time. As a result, when communication is made successful, the route is returned to the enabled state and concerning following communication, communication is performed while alternately using the duplexed routes.

摘要： PROBLEM TO BE SOLVED: To provide an autonomous distributed signal control system for performing optimal control over an entire control area by autonomously calculating a control pattern by a signal controller on each of crossings in accordance with a change in the traffic status of the entire area. SOLUTION: This system is provided with signal lights 3 and 4 provided on the respective crossings in the control area and a local station 2 for controlling the signal lights 3 and 4 respectively. On the basis of the traffic status on the crossing, the local station 2 decides which of the crossings is to be made a basic crossing or a cooperative crossing. On the basis of the traffic status within a range including the adjacent crossing, the basic local station decided as a basic crossing self-independently prepares the control pattern for controlling the crossing. On the basis of the traffic status on the cooperative crossing, the cooperative local station deciding the crossing as a cooperative crossing prepares the control pattern of the cooperative crossing while being cooperative to the control pattern of one of basic crossings.

摘要： PROBLEM TO BE SOLVED: To detect a fault without raising the load of a computer in an early stage by changing-over a duplexed gate way at every transmission event to use it. SOLUTION: The gate way of a transmission destination is executed by being changed-over into one of the duplexed gate ways 3a and 3b by the computers of the respective networks 1 and 2 at every event that a packet is transmitted to the computer of another network. At the time of normality without detecting a transmission error in the duplexed gate ways 3a and 3b, the gate ways to be used as a relay point is alternately changed-over whenever the transmission event occurs in the computer. Since the fault is detected at the point of time when the transmission event from the computer of a transmission source occurs at the time of the fault in one of the gate ways, the inquiry of soundness in the gate way is unnecessitated. When the fault is detected, usage is stopped, the normal gate way is preferentially used and transmission is continued.
