The present disclosure discloses a method of obtaining a seismic while drilling signal. The method comprises the following steps: arranging geophones by using a first observation method to obtain a first seismic reference signal and a second seismic reference signal; arranging geophones by using a second observation method to obtain first seismic data; arranging geophones by using a third observation method to obtain second seismic data; comparing the first seismic reference signal with the second seismic reference signal to obtain a first output reference signal, and optimizing the first output signal to obtain a second output reference signal. The present disclosure obtains square matrix and near-wellhead seismic while drilling data through the combination of geophone square matrix combined observation, near-wellhead observation, and survey line observation, the data acquisition efficiency is relatively high, the signal-to-noise ratio is high, and thus, the problem of near-surface noise interference is effectively solved.

Method of obtaining seismic while drilling signal

A display panel includes multiple pixel units that are arranged regularly. A pixel circuit is connected with a scanning signal line and a data signal line. The pixel circuit receives a data voltage transmitted by the data signal line and outputs a corresponding current to a light emitting device under a control of the scanning signal line. When a first light emitting unit is in a black state, the data signal line provides a reference black state voltage to a pixel circuit of the first light emitting unit. The driving method of the display panel includes: providing, by the data signal line, a first black state voltage to a pixel circuit of a second light emitting unit when the first light emitting unit emits light and the second light emitting unit is in the black state. The first black state voltage is less than the reference black state voltage.

Touch control auxiliary apparatus, protective casing, touch screen and mobile terminal

A street lamp integration device, a street lamp system and a communication method are disclosed. The street lamp integration device includes a local area network module configured to generate a local area network covering a first range, a traffic collector configured to collect traffic information in a second range and send the same to a communication module and the communication module configured to send the traffic information to a vehicle connected to the local area network. By extensive availability and close mutual distance of street lamps, a local area network is formed within the first range of each street lamp, which helps to to form a network of comprehensive coverage and extensive range. The traffic collector can collect traffic in a certain range and send the same to the vehicle connected to the local area network through the communication module, facilitating awareness of the current traffic by the vehicle.
