Concrete spreading quality control method

The invention relates to a concrete spreading quality control method. The concrete spreading quality control method comprises steps as follows: a, satellite positioning data of a spreading machine is received in real time; b, included angles of the spreading machine relative to the reference direction are collected by a position sensing device on the spreading machine in real time, so that the physical position of the spreading machine is judged; c, the acquired satellite positioning data and physical position are transmitted to a PLC (programmable logic controller), and the clock of a PLC program is synchronized with the standard time; d, the server compares a digitized map of a spreading construction area with the current working position range of the spreading machine according to various data of the PLC in the step c, and working state information of the spreading machine is acquired; e, spreading data of each spreading point is combined with the spreading design standard, and whether the spreading operation conforms to regulations is judged. According to the concrete spreading quality control method, the accurate data of the spreading machine state can be acquired automatically in real time, the spreading effect is monitored in real time, the condition of inconformity to dam spreading regulations is effectively avoided, and the overall smoothness of concrete is guaranteed to the greatest degree.
