EOG (Electrooculography)-based ERG (Electroretinography) signal acquisition and processing system and method

The invention discloses an EOG (Electrooculography)-based ERG (Electroretinography) signal acquisition and processing system and method. The system comprises a control unit, a retinal stimulator unit, an ERG signal acquisition unit and an ERG signal processing unit. The method comprises the following steps: adjusting illumination and flash rate of a stimulation light source; arranging three skin electrodes on the forehead just above eyes of a subject, on the inner sides of the eyes and the bridge of a nose and at eyelids respectively; performing dark adaptation for more than 20 minutes; aligning the eyes of the subject to the stimulation light source; acquiring an EOG signal; performing light stimulation on the eyes of the subject, synchronously acquiring the ERG signals on the inner sides of the eyes and the bridge of the nose and at the eyelids of the subject respectively, and storing after signal conditioning and AD (Analog-Digital) conversion; reading the ERG signals by an ERG signal processing and analysis unit and processing and analyzing the ERG signal. The ERG signals are acquired by using the external skin electrodes, so that the acquisition is more convenient and safer, and the cost is lower; for signal processing, the adopted method is small in operation and high in feasibility and can realize rapid signal processing.

Detection system and method for monitoring fracture development of coal pillar-free gob-side entry retaining floor

The invention relates to a detection system and a method for monitoring fracture development of a coal pillar-free gob-side entry retaining floor. The method comprises the following steps of chiseling a floor drilling field at one side of the coal pillar-free gob-side entry retaining, drilling in a floor rock layer according to different angles, gradually butting transparent hollow pipe sections by a butting sealing system, and sending into each drilling hole; grouting and anchoring a gap between each drilling hole and the corresponding transparent hollow pipe, enabling a detection positioning assembly to record the fracture of the drilling surrounding rock according to different scales of a measuring tape, performing monitoring tasks on evolution of floor mining failure rule for multiple times in different mining phases until the data is stable, and then finishing the observation. The method has the advantages that the floor small-angle drilling hole, the floor medium-angle drilling hole, and the floor large-angle drilling hole extend from the drilling field to the floor of a to-be-mined coal layer and are distributed in parallel in a stereo way; by observing the fracture condition of adjacent drilling holes in the same time and the fracture condition of the same drilling hole in different coal mining phases, the development state of the plastic failure area of the floor and the development state of the failure area of the floor after the coal bed is mined are determined, so as to provide reliable data reference for safety construction.

Acquisition method and system for running data of power grid equipment

The invention provides an acquisition method and an acquisition system for running data of power grid equipment, and achieves collection and wireless transmission of the running data of the power gridequipment in an area that an existing network is incapable to cover. Different transmission terminals are distinguished via IP addresses, so that the multiple transmission terminals access communication links with a receiving terminal in a TDMA manner, and communicate with the receiving terminal, and thus the receiving terminal can simultaneously acquire the running data of one or more pieces ofpower grid equipment from the multiple transmission terminals. During the communication process of each multi-access transmission terminal and the receiving terminal, the receiving terminal performs error checking on each received data packet via CRC cyclic redundancy checking, and coordinates retransmitted data packets that are unsuccessfully received by using an automatic retransmission request(ARQ); and after all the data packets are successfully received, the receiving terminal performs MD5 message digest algorithm integrity checking on the whole file, and finally, the accurate, efficient, secure and reliable collection and wireless transmission of the running data of the power grid equipment are achieved.
