The utility model discloses a settlement data acquisition device and a measurement system based on a diffused silicon pressure-sensitive sensing principle. The settlement data acquisition device comprises a double-cavity shell, a liquid guide pipe, an electrical pipe, a diffused silicon pressure-sensitive core and a mainboard, wherein the liquid guide pipe and the electrical pipe are communicated with the double-cavity shell; the diffused silicon pressure-sensitive core and the mainboard are arranged in the double-cavity shell; according to the measurement system, a plurality of settlement data acquisition devices arranged at a monitoring point and a datum point are connected in series, the liquid guide pipes connected in series are connected with the lower end of a liquid storage tank, and the pressure change signal is acquired. And the other electric pipe is connected with the upper end of the liquid storage tank to form an internal pressure self-balancing system, so that the influence of atmospheric pressu
