A pixel circuit includes a driver element that is supplied with a potential from a data line. The driver element controls a value of current passing through an electric light emitting element. Upon obtaining a threshold voltage, a conductive member connected to the electric light emitting element is made to be a floating state to cause the driver element to become on-state, variations in the potential of the conductive member caused by charges passing through the driver element to flow into the conductive member are detected by a threshold voltage detector to obtain the threshold voltage of the driver element.

Fine traffic monitoring is achieved in a network in which sFlow and OpenFlow are combined. Specifically, flow identifiers (flow IDs) for identifying flows (or groups of packets) are prepared, and the flow identifiers are stored in entries of flow tables to allow sFlow agents to specify the flow identifiers as data sources. Specifically, the flow identifiers are stored in cookies of entries registered in flow tables of switches from a controller, and operations are performed for received packets matching the rules of the entries in accordance with the actions defined in the entries. In the switches, the flow identifiers specified as data sources in the MIBs used in sFlow are obtained and statistic information of packets matching the entries is obtained on the basis of the flow identifiers.

Each unmanned aerial vehicle is provided with an independent unique electronic identification code by integrating a cell phone communication module into a flight control computer board card; as long as the system is started and electrified, the current relevant information of the unmanned aerial vehicle is transmitted to a remote control center; a permission instruction is necessarily applied from a control center for each flight; information such as an airway plan is made uniformly in the control center; and the information is transmitted to an operation terminal of the unmanned aerial vehicle through a cell phone communication module. Consequently the unmanned aerial vehicle cannot fly away without a headquarter control instruction. The state of each unmanned aerial vehicle is fed back to the control center and can be shared with networked data of relevant national supervision departments so as to play roles in unified supervision and scheduling. In addition, the on-site operation personnel do not need professional knowledge such as airway point setup; and the unmanned aerial vehicle can be operated by common people subjected to simple training, so that the problem of staff shortage in unmanned aerial vehicle control is solved.

When a network composed of usual switches on a communication route exists, in the network, a QoS control cannot be carried out to a user. Specifically, the switch receives a packet and issues a notice to an external controller and a user authenticating section of the controller determines a QoS policy of a flow. When a plurality of networks exists on the route, a route calculating section selects a route based on the QoS policy and topology data so as to pass through an appropriate network. A flow table generating section generates a flow table which carries out queuing based on the QoS policy and a marking of a DSCP value to a DS field of a header when transmitting a packet to the selected network, and registers the flow table for the round-trip on the switch.
