摘要： It is proposed a method for providing synchronization in a data acquisition system comprising a plurality of acquisition units. A given acquisition unit of the plurality carries out the following steps: receiving a packet from another device of the data acquisition system; extracting a synchronization accuracy information and a reference clock information from the received packet; obtaining a first reference clock as a function of the extracted reference clock information; if the extracted synchronization accuracy information indicates a better synchronization accuracy than a current synchronization accuracy information associated to the given acquisition unit : taking the obtained first reference clock as a selected reference clock and updating the current synchronization accuracy information to indicate a lower synchronization accuracy than the extracted synchronization accuracy information.

摘要： An aerostatic platform (201) for monitoring an earth-based sensor network (210). The aerostatic platform (201) includes an aerostat (231), at least one antenna (241) coupled with the aerostat (231), and a plurality (251) of restraints (251-1, 251-2, 251-3). The antenna (241) is configurable to receive a signal transmitted from at least one sensor (210-1) in the earth-based sensor network (210). The plurality (251) of restraints (251-1, 251-2, 251-3) is configurable for fixing the antenna (241) in a fixed aerial location (115-1) above the earth-based sensor network (210), and for maintaining the antenna (241) in a sufficiently stationary position relative to the sensor (210-1) to triangulate a location (110-1) of the sensor (210-1) from a locator signal received by the antenna (241). A sensor-network-monitoring system (401) is also provided, along with a method for deploying the sensor-network monitoring system (401).

摘要： Presented are systems and methods for wireless data acquisition. The wireless data acquisition may involve synchronizing modules within a data acquisition array. The synchronized data acquisition array may be used to facilitate a seismic survey. Synchronization may be facilitated by receipt of a reference time event such that a clock is synchronized based on the reference time event.

摘要： A system and method for acquiring seismic data is provided that utilizes a plurality of field station (data acquisition) units placed over a region of interest and a remote central unit. The system and method, in one aspect, determine a condition associated with each of a plurality of preselected attributes relating to the acquisition of the seismic data at each of the field station units, generate messages at each field station when the condition of any particular attribute meets a selected criterion, and transmit the generated messages to a remote unit wirelessly. The system and methods provide efficient use of the available bandwidth and avoid collisions among messages transmitted simultaneously by several field station units.

摘要： The transmission method utilizes multiple seismic acquisition units (12) within an array (14) as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station (16). Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path. Utilizing an array of seismic units permits transmission routes back to a control station to be varied as needed. In transmissions from the most remote seismic unit to the control station, each unit within a string (18) receives seismic data from other units and transmits the received seismic data along with the receiving unit's locally stored seismic data. As transmission is passed along the chain, it is bounced between seismic units to be relayed by each unit in the array.

摘要： A seismic data acquisition system is featured that utilizes a series of nearly identical seismic shots (SISS) to synchronize and to communicate with novel data acquisition units (NDAU) located in the field. Each SISS seismic shot is carefully timed to provide synchronization to each NDAU, and to allow the NDAU to correct for the time drift of its internal clock. Further, each NDAU is programmed with a number of menus, which are used to interpret the seismic shots received from a seismic source. Thus, communication from a central or headquarter site to each NDAU is facilitated, allowing for a change in production schedule and other variables. In addition, the disclosed seismic data acquisition system features movable SISS source sites and overlapping production and SISS shots.
