Abstract: A method for configuring and updating random access resources in a multi-antenna multiple-input multiple-output (MIMO) environment is provided, including: initializing a base station; broadcasting, by the base station, the available RACH resources using an SIB2; initiating, by users who have data to be sent in an uplink, random access processes on the RACH resources configured by the base station; and redefining an S state, an I state, and a C state. Configuration of the RACH resources may be gradually and dynamically optimized according to the quantity of antennas of the base station and a utilization rate threshold of the RACH resources, so that waste of random access RACH resources is reduced provided that an MIMO system meets a required user/service access success probability; a utilization of the resources is improved by fully utilizing spatial diversity characteristics of the MIMO system.

Abstract: An intelligent vehicle capturing apparatus for a high-pier bridge includes: a double-layer metal protective net, support unit and actuation unit connected thereto. The protective net mounts to a high-pier bridge backside through the support unit. The actuation unit includes a hydraulic link mechanism connected to one end of the protective net. The hydraulic link mechanism unwinds the protective net to capture a vehicle. The apparatus stops a vehicle rushing off a high-pier bridge. Upon completion, a hydraulic system drives a third hydraulic cylinder in a support rod on the high-pier bridge backside driving a rolling shaft rotating, winding and placing a protective net on the high-pier bridge backside. The apparatus has a simple structure, is practical and easily used, useful on hazardous high-pier bridges protecting vehicle passengers and avoiding traffic accidents resulting from vehicles rushing out of the high-pier bridges.
