The invention discloses a knitting method for a knitted decorative picture and the knitted decorative picture. The knitting method for the knitted decorative picture comprises the following steps that 1, a pattern of the knitted decorative picture is designed, wherein the main body pattern of the knitted decorative picture is drawn; 2, knitting tools and materials are selected according to the drawn main body pattern of the knitted decorative picture in the step 1; 3, a background of the knitted decorative picture is selected, and a main body diagram of the knitted decorative picture is made; 4, the main body diagram of the knitted decorative picture is placed on the background of the knitted decorative picture and mounted by a picture frame, and then the knitted decorative picture is obtained. According to the knitting method for the knitted decorative picture and the knitted decorative picture, the knitting method is easy so that people can quickly knit the knitted decorative picture with the higher quality, and the phenomenon that the aesthetics of the knitted decorative picture and the harmony with the environment are influenced caused by deformation due to the fact that the knitted decorative picture is affected with damp cannot occur.

The invention relates to a down-hole information acoustic wave signal relay system. The down-hole information acoustic wave signal relay system comprises an upper connector, an instruction bin protective cylinder and a lower connector which are sequentially connected. An energy converter protective cylinder, an instrument bin and an accelerometer protective cylinder which are sequentially connected are arranged in the instruction bin protective cylinder. The end of the energy converter protective cylinder is matched with the upper connector, and the end, connected with the accelerometer protective cylinder, of the instrument bin is connected with the end of the instruction bin protective cylinder. The end of the accelerometer protective cylinder is matched with the lower connector, and an energy converter is installed in the energy converter protective cylinder. A circuit module is arranged in the instrument bin and comprises an energy converter driving circuit, a coding and transcoding circuit and a decoding circuit, and an accelerometer is arranged in the accelerometer protective cylinder. According to the down-hole information acoustic wave signal relay system, while normal well drilling is kept, real-time receiving of acoustic wave signals carrying well drilling information and from the lower portion of a drilling pillar is achieved; the effective signals are enlarged and then occurs again, long-distance stable transmission of the well drilling information is achieved, and the damping problem when the acoustic wave signals carrying the well drilling information are transmitted is solved; and drilling fluid and a stratum are not relied on, the noise interference resistance capacity is high, real conversion of the well drilling information is achieved, and the application range is wide.

The invention relates to an underground pressure monitoring device. The underground pressure monitoring device comprises an energy converter, an energy converter driving circuit, an encoding transcoding circuit, an annular pressure measuring element and a drill column internal pressure measuring element, wherein the energy converter, the energy converter driving circuit and the encoding transcoding circuit are connected with each other in turn; the annular pressure measuring element and the drill column internal pressure measuring element are respectively connected with the encoding transcoding circuit; an annular pressure signal measured by the annular pressure measuring element and a drill column internal pressure signal measured by the drill column internal pressure measuring element are transmitted to the encoding transcoding circuit for encoding and transcoding; the transcoded pressure signal is transmitted to the energy converter driving circuit for driving the signal; the energy converter is driven by the energy converter driving circuit to convert the transcoded pressure signal into a sound wave signal and then send the sound wave signal. The underground pressure monitoring device can achieve the purpose of accurately real-time converting the underground pressure into the sound wave signal while normally drilling; the drill column is used as a transmission channel and is independent of the drilling liquid; the noise jamming resistance is high; the transmission rate is high and the error rate is low; the underground pressure monitoring device is not influenced by the underground complex conditions, such as, gas invasion.
