In, control module reads the pressure value of the adjustable supporting leg of each bar (a, b, c, d) by data acquisition module, when adjustable supporting leg pressure
When power is less than threshold value, represents supporting leg and do not land, then continue to discharge underwater platform；If the pressure of certain adjustable supporting leg is more than threshold
Value, then represent this adjustable leg and land, and control module gathers the inclination angle of obliquity sensor by data acquisition module BOB(beginning of block)
Value (X, Y), and calculate the inclination angle in platform operations face, when the inclination angle in platform operations face is more than threshold value (n), illustrate that sea bed face is oblique
Face (slope), then underwater platform stopping is discharged, and starts above to carry a segment distance, then changes prospecting position；If platform operations face
Inclination angle is less than threshold value, then underwater platform can continue to transfer, until platform lands.After platform lands, if the pressure of certain supporting leg is little
In threshold value, this leg is judged to empty leg, then need to harmonize (make this supporting leg extend), if to exceed setting range (such as super for adjustment scope
Cross the range of hydraulic cylinder), then change prospecting position；If the pressure of each bar supporting leg, all in normal range (NR), shows under water
Platform normally lands, and process of discharging terminates, and can start exploration operation.
After underwater platform discharges success, due to when underwater operation (sampling or in-situ test), water impact on sea bed, wash away
And vibration equipment is so that the equipment based on platform base produces inclination angle, control module will implement prison by certain time interval (T)
Survey, with the intelligent automatic leveling of uninterrupted mode it is ensured that the exploration path of exploring equipment on underwater platform all the time with sea bed face
Vertically.As shown in fig. 6, control module reads inclination value (X, Y) by data acquisition module, using peak is motionless, low spot is " single
To regulation " leveling algorithm, minimum point X-direction leveling, then minimum point Y-direction leveling, if there being empty leg after leveling, continues to adjust
Flat, otherwise leveling terminates.
Below the using method of above-mentioned underwater platform is illustrated, the method comprises the following steps：
(1) install：Each for above-mentioned underwater platform building block is placed in container or packing case, transports to exploration scene
