    摘要: The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator (or using tele-operation whereby the operator views a screen displaying live views from vehicle-mounted cameras and using remote controls) along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile including a vehicle path, a sequence of local metric submaps located along the path, and a profile of desired speed as a function of distance along the path. During the playback step, the vehicle automatically repeats the route that was taught during the teaching phase, as represented by the route profile. This is accomplished by first determining where the vehicle is on the route using a localization method which uses the odometric and laser rangefinder sensors and the local metric maps to determine the vehicle location. A steering control method adjusts the vehicle's steering to ensure it tracks the intended path. A drive control method adjusts the vehicle's speed accordingly and safety method ensures the vehicle stops in the event that an obstruction is on the vehicle's intended path.

    摘要: A low voltage control circuit is provided for individually controlling high voltage power provided over bus lines to a multitude of interconnected loads. An example of a load is a drive for capillary channels in a microfluidic system. Control is distributed from a central high voltage circuit, rather than using a number of large expensive central high voltage circuits to enable reducing circuit size and cost. Voltage is distributed to each individual load and controlled using a number of high voltage controller channel switches connected to high voltage bus lines. The channel switches each include complementary pull up and pull down photo isolator relays with photo isolator switching controlled from the central high voltage circuit to provide a desired bus line voltage. Switching of the photo isolator relays is further controlled in each channel switch using feedback from a resistor divider circuit to maintain the bus voltage swing within desired limits. Current sensing is provided using a switched resistive load in each channel switch, with switching of the resistive loads controlled from the central high voltage circuit.
