Automatic vehicle lane changing method

The invention discloses an automatic vehicle lane changing method. The automatic vehicle lane changing method includes the steps that user lane change information and lane changing mode confirmation information are received; a preset area of a vehicle is monitored, environmental data around the vehicle is acquired in real time and target vehicles are screened, and environmental data around each target vehicle is acquired; the weight of each target vehicle is calculated to determine whether the vehicle meets the lane changing condition or not; if the lane changing condition is not met, the vehicle is fed back to abandon lane changing; and if the lane changing condition is met, the target vehicle with the smallest weight is selected as a lane changing vehicle, the lane changing path is planned, and the automatic lane change of the vehicle is executed. The automatic vehicle lane changing method can not only screen the lane changed vehicle, complete the lane changing path planning and execute the automatic lane changing, but also can monitor the lane changed vehicle in real time and alert the collision risk and assist the coordinated lane changing of the lane changed vehicle, and the safety of the vehicle lane changing is increased; and the fault tolerance is increased, the risk caused by human error operation is reduced, and the driving experience of a user is improved.

Wireless humiture sensor network structure based on zigbee

The invention provides a wireless humiture sensor network structure based on a zigbee, relates to the wireless humiture sensor technology, and solves the problem that the security of running devices in a cabinet of a machine room is not guaranteed. The structure comprises a plurality of wireless humiture sensors based on the zigbee which are distributed in each cabinet of the machine room, a ZigBee wireless gateway, and a control center host. The wireless humiture sensors collect a humiture signal in the cabinet, preprocess the signal into humiture data in a ZigBee protocol format, and transmit the humiture data; the ZigBee wireless gateway receives, through a ZigBee network, the humiture data in the ZigBee protocol format transmitted by the wireless humiture sensors, and transforms the humiture data in the ZigBee protocol format into the humiture data in an Ethernet protocol format; and the control center host, through an Ethernet telecommunication transmission, receives the humiture data in the Ethernet protocol format transmitted by the ZigBee gateway, and displays the humiture data in a real time manner. The sensor network structure can display the humiture in the cabinet in the control center host in the real time manner, so as to ensure the safe operation of devices in the cabinet.

Program play method and related device and system

The invention discloses a program play method and a related device and system. The program play method provided by the embodiment of the invention comprises the following steps: receiving an abnormal event data packet of a first program transmitted by a playing terminal, wherein the abnormal event data packet comprises information on abnormal event type, to which the first program belongs, reported when a user watches the first program played by the playing terminal; adjusting the report frequency of the abnormal event type, to which the first program belongs, according to the abnormal event type to which the first program belongs; judging whether the adjusted report frequency of the abnormal event type, to which the first program belongs, is greater than a preset threshold value; when the judgment result is yes, transmitting data of a second program to the playing terminal to play the second program by the playing terminal. By using the method and the system, the user judges and reports abnormal programs according to the played programs, the information on the abnormal programs reported by the user is transmitted to a play server by the playing terminal, and play control over the programs is realized by the play server according to the preset threshold value of the report frequency.

System and method of implementing limitation of public network access user number based on Linux for CPE (Customer Premise Equipment)

ActiveCN104270325AA large amountSatisfy the requirements of simultaneous access to the public networkData switching networksDevice typeGNU/Linux
The invention discloses a system and a method of implementing limitation of a public network access user number based on a Linux for CPE (Customer Premise Equipment), relating to the field of CPE equipment. The system comprises a DHCP (Dynamic Host Configuration Protocol) module and a public network user access number limiting module, wherein when the DHCP module checks status information of equipment at a LAN (Local Area Network) side at each time, an iptables forwarding table rule is eliminated, and the previous check information is eliminated, so that the current result is taken as a standard at each check; the public network user access number limiting module is used for eliminating recorded blacklist and whitelist and un-limiting the public network user access number if a public network user access number limiting function is closed, and obtaining an IP (Internet Protocol) address of the equipment at the LAN side, carrying out terminal identification through DHCP Option60 and distinguishing the equipment type if the public network user access number limiting function is opened. According to the system and the method, the maximum quantity for synchronous access of the public network can be limited, individual limitation of the public network access number can be carried out on each terminal type, and a function of individual limitation of the public network access number is enriched.
