Wireless sensor network-based greenhouse group control system and control method thereof

The invention discloses a wireless sensor network-based greenhouse group control system and a control method thereof. Each greenhouse is provided with a plurality of wireless sensor nodes and a cluster head node for acquiring environmental factors of the greenhouses according to needs, wherein the wireless sensor nodes and the cluster head nodes autonomously form wireless sensor networks by wireless communication; the wireless sensor nodes transmit monitoring data to the corresponding cluster head nodes in a multi-hop way; the cluster head nodes transmit the data to a gateway node which uploads the data to a communication server; the communication server performs two-way communication with a control computer; and the control computer makes corresponding guidance schemes according to the data monitored by the wireless sensor networks in real time, and synchronously transmits control instructions to the wireless sensor networks according to the guidance schemes. In the system and the method, the real-time data monitored by each sensor node in the greenhouses can be timely and accurately acquired, and the control instructions can be fast transmitted to the sensor nodes after specific production guidance is made or early-warning setting is performed according to the monitoring data.

Charge and passenger flow information acquisition method for bus IC (integrated circuit) cards

The invention discloses a charge and passenger flow information acquisition method for bus IC (integrated circuit) cards and belongs to the technical field of transportation. After segmental decreasing rate and the effective time duration of accumulative distance are continuously accumulated by a vehicular terminal according to riding distance, charging by distance is completed by swinging at the moment of boarding and alighting, and data related to boarding and alighting of passengers are uploaded to an information center. Data such as boarding flow, alighting flow, OD (origin and destination) flow and interchange flow on specified time scale are acquired first in real time from the information center terminal according to a specific line, a specific area and an additionally designated traffic zone; the data such as the ratio of passengers ranging from average riding distance to different riding distances and the ratio of passengers ranging from average riding time and different riding times on specified time scale are obtained then in non-real time. Real-time acquisition of bus passenger flow information and continuous acquisition of bus riding feature information are achieved by the method while fairness in public resources consumption is improved effectively, and information base for the fair charge and the related decisions for buses are provided.
