Method of providing connector compatibility for data interface
View Patent ↗Cable connection unions are rapidly replaced in a universal seismic data acquisition-module without opening a main electronic circuitry protective chamber. Different connector types required for the many data transmission cable designs needed to service a wide range of survey conditions are more easily accommodated without exposing primary circuitry to the elements.
1. A method of providing connector compatibility between seismic data acquisition cables and a seismic data processing module comprising the steps of:
(a) securing data processing circuitry within a first environmental isolation chamber;
(b) linking said data processing circuitry with a signal transfer conduit to a first cable connection joint, said signal transfer conduit traversing an environmentally sealed first partition between said first chamber and a second environmental isolation chamber;
(c) closing an access opening into said second isolation chamber with an independently removable second partition;
(d) securing a cable connection union to said second partition to dispose an internal cable connection joint within said second chamber for connection with said first connection joint and an external cable connection joint disposed externally of said second chamber for selective connection with a data acquisition cable joint; and,
(e) selectively opening said second isolation chamber without disturbing said first isolation chamber for exchanging said external cable connection joint to coordinate the compatibility of said external cable connection joint with a desired data acquisition cable joint.
2. The method as described by claim 1 wherein said first partition is secured to said first chamber by a plurality of first removable fasteners and said second partition is secured to said second chamber by a plurality of second removable fasteners.
3. The method as described by claim 2 wherein said second removable fasteners may be removed without disturbing said first removable fasteners.
4. The method as described by claim 1 wherein walls surrounding said second chamber are materially integrated with said first partition.
5. The method as described by claim 1 wherein said first environmental chamber is provided with a plurality of access openings that are sealed by respective first partitions.
6. The method as described by claim 5 wherein walls surrounding said first partitions are materially integrated with walls surrounding respective second chambers.
7. The method as described by claim 1 wherein at least a pair of signal transfer conduits link said data processing circuitry to a respective pair of first cable connection joints, said signal transfer conduits traversing a respective pair of environmentally sealed first partitions between said first chamber and a respective pair of second environmental isolation chambers, providing removable second partitions respective to independent access openings for each of said second environmental isolation chambers, and, securing a cable connection union to each of said second partitions to receive respective first cable connection joints within each of said second environmental isolation chambers.
8. The method as described by claim 7 wherein said first partitions are secured to said first chamber by a plurality of first removable fasteners and said second partitions are secured to said second chamber by a plurality of second removable fasteners.
9. The method as described by claim 8 wherein said second removable fasteners may be removed without disturbing said first removable fasteners.
10. The method as described by claim 7 wherein walls surrounding said second chambers are materially integrated with said first partitions.
