10. An intelligent management method of a wheel stopper for a motor train unit is applied to the intelligent management system of the wheel stopper for the motor train unit according to any one of claims 1 to 9, and comprises a wheel stopper hanging process, a wheel stopper returning process and a wheel stopper position determining process:
the process of hanging the wheel stopper comprises the following steps:
s10, acquiring the row position of the scotch block required by the input of an operator, and acquiring the work card information of the operator;
step S11, the system judges whether the operator has the authority to operate the wheel stopper according to the work card information, if so, the cabinet door corresponding to the storage unit is popped up, the second voice module prompts the operator to take the wheel stopper, and the storage unit indicator light is changed from the state with the wheel stopper to the state without the wheel stopper; if no authority exists, the second voice module prompts the operator to have no operation authority through voice;
step S12, after acquiring the scotch block, an operator needs to reach a corresponding column position within a specified time, the identification terminal is used for verifying the identity of the scotch block, if the identities correspond to each other, the system prompts the scotch block to be hung under the corresponding motor train unit wheel, and if the time is exceeded or the identity is wrong, an alarm is generated to inform corresponding management and operators;
step S13, after the scotch block is hung, the state judgment circuit periodically generates a state signal, the state signal is transmitted to the monitoring server through the low-power wireless network transmission module, and if the monitoring server cannot obtain the correct state signal in a certain signal period, the monitoring server sends an alarm command to the corresponding scotch block;
step S14, when the scotch block is hung successfully, the train position indicator light is changed from a state without the scotch block to a state with the scotch block, and the corresponding train position is forbidden to go out;
the scotch block return process comprises the following steps:
step S20, removing the scotch block by an operator, and storing the scotch blocks in the intelligent fixed cabinet in a centralized and unified manner;
step S21, the intelligent setting cabinet feeds back the state of the wheel stopper in the cabinet, checks the identity of the wheel stopper, automatically locks the cabinet door if the identity is correct, generates an alarm notice if the identity is wrong, and prompts correct operation;
step S22, after the locker door is successfully returned and automatically locked, the storage unit indicator light is changed from the state without the wheel stopper to the state with the wheel stopper, and the train position indicator light is changed from the state with the wheel stopper to the state without the wheel stopper, so that the vehicle is allowed to exit;
the scotch block position determination process includes the steps of:
step S30, the wheel stopper sends data to a plurality of wireless communication base stations at the same time, and the monitoring server calculates the approximate position of the wheel stopper by a ranging positioning algorithm, because the signal strength received by the wireless communication base stations has differences due to different distances;
and step S31, when the scotch block is lost or abnormal, sending an alarm command to the scotch block through the monitoring server, wherein the scotch block generates a sound alarm, so that managers and operators can manually search the final position of the scotch block through sound at the approximate position calculated by the ranging positioning algorithm.
