    摘要: Système de transmission par radio entre un laboratoire central (1) de commande et d'enregistrement et des boîtiers d'acquisition (BL) répartis où des unités de transmission relais (3) sont utilisées pour communiquer avec des boîtiers inaccessibles directement (BLRR).
    Il comporte une unité de centralisation (7) adaptée à gérer les échanges d'ordres ou de données du laboratoire central (1) avec les boîtiers accessibles directement (BLRD) au moyen d'une liaison radio dans une première bande de fréquence (f2) d'une part et avec les unités relais (3) au moyen d'une liaison radio dans une autre bande de fréquence (f1). Celles-ci gèrent les liaisons radio avec les boîtiers inaccessibles (BLRR) au moyen de liaisons radio à une fréquence (f3) distincte de (f2). Les unités relais (3) et l'unité de centralisation (7) sont programmées pour gérer automatiquement les liaisons entre le laboratoire central (1) et n'importe lequel des boîtiers (BL), qu'elles soient directes ou indirectes, et d'autre part pour réserver une partie du temps d'interrogation de chaque boîtier à la transmission de données de service indicatives de leur bon fonctionnement.

    摘要: It is proposed a data acquisition apparatus (1), comprising:
    - a receiving antenna (63), receiving a radio communication signal including synchronization information representative of a remote reference clock signal;
    - a local clock circuit (8), delivering a local clock signal (CLK);
    - a gauging circuit (61), measuring a frequency drift and a phase error of the local clock signal (CLK) in view of the synchronization information;
    - an analog-to-digital converter (3), providing a series of digital sampled and dated data according to the local clock signal (CLK); and
    - a correcting circuit (4), correcting the series of digital sampled and dated data based at least on the measured frequency drift and phase error.

    摘要: It is proposed a method for collecting, in a collecting device distinct from a central unit, data coming from a plurality of seismic acquisition units. The method comprises a step of assigning at least one device as a sink unit. For a given sink unit, the method also comprises the following steps for data specific to at least one seismic acquisition unit not assigned as a sink unit: transmitting the specific data from the at least one seismic acquisition unit to the given sink unit, via a radio path established in a radio multi-hop network built at least with the given sink unit and the plurality of seismic acquisition units; and transmitting the specific data from the given sink unit to the collecting device, via a link.

    摘要: A system and method for acquiring seismic data is provided that utilizes a plurality of field station (data acquisition) units (208) placed over a region of interest and a remote central unit (202). 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 (208), generate messages at each field station (208) when the condition of any particular attribute meets a selected criterion, and transmit the generated messages to a remote unit (202) wirelessly. The system and methods provide efficient use of the available bandwidth and avoid collisions among messages transmitted simultaneously by several field station units (208).
