  • Patent number: 11088782
    Abstract: Aspects of the invention include using a cyclic redundancy code (CRC) multiple-input signature register (MISR) for early warning and fail detection. Received bits are monitored at a receiver for transmission errors. The monitoring includes receiving frames of bits that are a subset of frames of bits used by the transmitter to generate a multi-frame CRC. At least one of the received frames of bits includes payload bits and a source single check bit not included in the multi-frame CRC. It is determined whether a transmission error has occurred in the received frames of bits. The determining includes generating a calculated single check bit based at least in part on bits in the received frames of bits, and comparing the received source single check bit to the calculated single check bit. An error indication is transmitted to the transmitter if they don't match.

  • Patent number: 10306339
    Abstract: It is necessary to increase the scale of a sensor network to achieve high resource exploration efficiency. On the other hand, since there are increasing needs to extend the area of an exploration region and to detect deeper geological stratum and crust structures more accurately, the large-scale sensor network needs to be operated for a long period of several weeks or longer. In order to solve the problem, a sensor unit needs to be turned on always to perform measurement always. However, an auxiliary measurement unit is activated intermittently since the auxiliary measurement unit needs to acquire data at necessary timings only. On the other hand, during collection and transmission of data and charging of a battery, a sensor terminal detects whether power is supplied from a data collection and charging device and automatically turns off the sensor unit and the auxiliary measurement unit to activate a data transmission unit.

  • Patent number: 8885441
    Abstract: The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. 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 receives seismic data from other units and transmits the received seismic data along with the receiving unit's locally stored seismic data. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array.

  • Publication number: 20130148470
    Abstract: Systems and methods are provided for acquiring seismic data using a wireless network and a number of individual data acquisition modules that are configured to collect seismic data and forward data to a central recording and control system. In one implementation, a number of remote modules (301) are arranged in lines. Base station modules (302) receive information from the lines and relay the information to a central control and recording system (303). Radio links operating on multiple frequencies (F1-F12) are used by the modules (301). For improved data transfer rate, radio links from a remote module (301) leap past the nearest remote module to the next module closer to the base station.

  • Patent number: 8254207
    Abstract: In various embodiments, seismic receivers may detect seismic energy and transmit digital signals representative of the seismic energy to an S-line interface module (SLIM) and/or a smart antenna module (SAM) for collection. A SLIM may be used to connect two or more seismic receivers together. A SAM may include a memory medium for storing digital signals from seismic receivers (e.g., received directly from the seismic receivers or received through a connection to a SLIM) and a wireless transmitter to transmit data stored on the memory medium.

The unit may include an additional geophone to mechanically vibrate the unit to gauge the degree of coupling between the unit and the earth. The unit may correct seismic data for the effects of crystal aging arising from the clock. Deployment location of the unit may be determined tracking linear and angular acceleration from an initial position. The unit may utilize multiple geophones angularly oriented to one another in order to redundantly measure seismic activity in a particular plane.
