Method for automatically reporting station of public transport vehicle

ActiveCN101493990AAccurate and timely station announcementEasy to schedule and manageRoad vehicles traffic controlBroadcastingData sequences
The invention relates to an automatic stop announcement method of a bus, pertaining to a bus information-releasing method. The method solves the problems of difficult data adjustment and low accuracy of stop announcement under a complicated situation, and comprises the following steps: a bus terminal receives and stores a data sequence of stop announcement in a running route, sent out by a control center through mobile communication. When the bus is in running, the bus terminal first combines current GPS location information with stop location information of auxiliary beacons to periodically find out the nearest stop as a current stop in the running route from the data sequence of the stop announcement. The running modes, namely, the uplink or the downlink, is determined when the bus runs into the current stop. And then the bus terminal adjusts the running mode according to the data sequence, controls the broadcasting and displays the information of the current stop; when the bus leaves the stop, the bus terminal, combining the running mode and in accordance with the data sequence, controls the broadcasting and displays leaving information consisting of the name of the next stop, and sets the next stop in the running route as the current stop.

Compositions and methods for improving the nutritional and physiological status of a woman and her child during all stages of pregnancy are provided herein. This includes pre-conceptional women, pregnant women, and post-natal women (both lactating and non-lactating mothers). The compositions are particularly useful for the neurological, visual, and cognitive development of an embryo, fetus, or infant and the nutritional and physiological well-being of the mother, fetus, and infant. The compositions contain one or more folates, such as a reduced folate and/or folic acid, and one or more essential fatty acids (EFA), such as an omega-3 and/or omega-6 fatty acid. The addition of the essential fatty acid improves upon the folate containing nutritional preparations described in the prior art. The one or more folates and essential fatty acid may be administered together or in separate dosage units. The one or more folates may be selected from folic acid/folate, one or more reduced folates, or a combination of folic acid/folate and one or more reduced folates. The reduced folate is preferably 5-methyltetrahydrofolate, and most preferably 5-methyl-(6S)-tetrahydrofolic acid. The essential fatty acid is preferably an omega-3 fatty acid, and is preferably docosahexenoic acid (DHA) derived from a vegetarian or non-fish source. The compositions may optionally contain other vitamins, minerals, and ingredients, such as, emollient laxatives—all defined herein as “optional or other ingredients”.

Fault simulation method and system for flight control system

InactiveCN105259788AShorten the argumentation processReduce development riskSimulator controlSimulation testingManagement system
The invention discloses a fault simulation method and system for a flight control system, and belongs to the field of flight control systems. The system mainly comprises a flight control system testing control platform, a simulation management system, and a bus signal simulation system. The flight control system testing control platform collects the output of the flight control system, and correspondingly transmits the output to the simulation management system. The simulation management system carries out dynamics mathematic model solving and transmits the solving results to the bus signal simulation system. The bus signal simulation system converts the solving results into various types of bus simulation signals, needed by the flight control system, through a bus signal conversion device, and transmits the signals to the flight control system. The flight control system makes the corresponding posture response according to various collected bus simulation signals. During fault simulation testing, the flight control system testing control platform sets various faults of the flight control system in real time through corresponding fault setting means, thereby achieving the testing of the response capability of the flight control system to various faults.
