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. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
L'invention concerne un système et un procédé d'acquisition de données sismiques mettant en AEuvre une pluralité d'unités stations locales (d'acquisition de données) placées dans une zone d'intérêt et une unité centrale distante. Dans un aspect, ces système et procédé consistent à déterminer une condition associée à chaque attribut d'une pluralité d'attributs présélectionnés relatifs à l'acquisition des données sismiques au niveau de chaque unité station locale, à générer des messages au niveau de chaque station locale lorsque la condition d'un attribut particulier répond à un critère sélectionné, et à transmettre sans fil les messages générés à une unité distante. Ces système et procédé permettent d'utiliser efficacement la largeur de bande disponible et d'éviter les collisions entre les messages transmis
