Static cone penetration system

The utility model relates to the field of measuring instruments, in particular to a static cone penetration system which is characterized in that a probe is provided with an inclination survey sensor and an analog-to-digital conversion module; the inclination survey sensor is connected with the probe and a data acquisition instrument; and the analog-to-digital conversion module is connected with a static cone penetration sensor and the data acquisition instrument. The static cone penetration system has the advantages that the whole AD switching process of the static cone penetration sensor is fulfilled in the probe, so as to avoid impact on measured data caused by cable circuits and the external environment; and a tri-axial acceleration inclination survey module is used for measuring an inclination angle, so as to acquire tip resistance, side wall resistance and the inclination angle of the probe during the pressing-in process of the probe.
