the central controller reads the RFID label through the RFID card reader; when the central controller reads the RFID label through the RFID card reader, the first electric control switch is controlled to be powered on or the motor is controlled to rotate at a speed not exceeding a first preset rotating speed; when a preset time passes after the central controller does not read the RFID label through the RFID card reader or does not read the RFID label from the RFID card reader; controlling the first electric control switch to act to cut off the power supply of the motor or controlling the motor to rotate at a speed not exceeding a second preset rotating speed;
the first preset rotating speed is greater than the second preset rotating speed.
9. The kart safety control system according to claims 1 to 8, wherein the received weight detected by the weight sensor, temperature value detected by the temperature sensor, and stress value detected by the stress sensor are substituted into a pre-established judgment model at the central controller to determine a control mode of the motor and/or an operation mode of the infrared distance measuring sensor;
the judgment model establishing step is as follows:
establishing a judgment condition database by using the weight detected by the weight sensor, the temperature value detected by the temperature sensor and the stress value detected by the stress sensor under the test condition, and establishing a judgment condition matrix according to different parameter values of different judgment conditions contained in the judgment condition database, wherein the judgment conditions are as follows:
Figure FDA0002654050500000051
wherein, amnAn nth parameter value representing an mth judgment condition;
establishing a judgment result matrix according to the judgment result corresponding to each judgment condition of the judgment condition matrix; the judgment result comprises: the control mode of the motor and the working mode of each infrared distance measuring sensor; the judgment result matrix is as follows:
Figure FDA0002654050500000052
wherein A ismjThe working mode of the jth infrared ranging sensor representing the mth judgment result; b ismThe control mode of the motor representing the m-th judgment result;
when the kart runs, the central control module acquires the weight detected by the weight sensor, the temperature value detected by the temperature sensor and the stress value detected by the stress sensor in real time, and establishes a judgment vector H, wherein the judgment vector H is as follows:
H＝(h1,h2,…,hn)；
wherein h isnIs the nth judged value;
calculating the similarity between the judgment vector H and each judgment condition of the judgment condition matrix, wherein the calculated formula is as follows:
Figure FDA0002654050500000053
wherein D isiIs the similarity of the judgment vector and the ith judgment condition of the judgment condition matrix, aikIs the parameter value h of the ith row and the kth column of the judgment condition matrixkThe k-th judgment value is the judgment direction;
determining the maximum similarity in the similarities of the judgment vector H and each judgment condition of the judgment condition matrix, so as to obtain a corresponding judgment result from the judgment result matrix; and switching the control mode of the motor and the working modules of the infrared distance measuring sensors based on the judging structure.
