5. The low-quality bulk coal rapid inspection system according to claim 1, wherein: the balance I (5) is a balance with the sensing quantity of 0.1mg, the measuring range of 220g and the in-band calibration function, and can transmit the weighed crucible mass and the sample mass to the master control software (6) through a serial port and the master control software (6).
6. The low-quality bulk coal rapid inspection system according to any one of claims 1-5, wherein: because the inferior scattered coal rapid detection system comprises moisture, ash, volatile and total sulfur tests, and more parameters need to be input and displayed, a control mode of an upper computer and a lower computer is adopted, and total control software (6) reads weighing data of a balance I (5) through a serial port and communicates with a moisture test unit (1), the volatile test unit (2), an ash test unit (3) and a total sulfur test unit (4), so as to control the test flow of the moisture test unit (1), the volatile test unit (2), the ash test unit (3) and the total sulfur test unit (4), read data and state information of the moisture test unit (1), the volatile test unit (2), the ash test unit (3) and the total sulfur test unit (4), and automatically calculate results and upload data to the inferior scattered coal rapid detection system.
