Description

Express delivery system, method, device, equipment and storage medium Technical Field The invention relates to the technical field of express delivery transportation, in particular to an express delivery conveying system, an express delivery conveying method, an express delivery conveying device, express delivery conveying equipment and a storage medium. Background In a large-scale allocation center in the express industry, express delivery of an incoming port and an outgoing port is required to be sorted by an express delivery sorting and conveying system and then conveyed to a corresponding outlet position. The sorting and conveying system mainly adopts a matrix-type gridding sorting mode, a plurality of port inlets collect express information through a DWS information acquisition and management system (DWS), a balance line on a transverse sorting line is utilized to accurately sort and convey the express to a plurality of longitudinal express destination conveying lines of a port, the transverse DWS balance line throws out the express to a balance wheel of a destination position when the balance line throws out the express, the thrown-out express slides down onto a conveying belt of the longitudinal conveying lines through a chute, the longitudinal conveying lines convey the express to a port outlet, a inspector sweeps codes to sort the express packages and load the express vehicles, one longitudinal conveying line generally comprises a plurality of connected conveying belts, one section of conveying belt is generally 12 m long or is of unequal in field size design, the conveying belt is driven by a motor to convey the express falling down on the chute connected with the transverse sorting line to the tail end of the longitudinal conveying line, and the sorting operator scans the express information sweeping system through the chute and conveys the express to the destination warehouse for entering. The transverse sorting lines and the longitudinal conveying lines form a cross express conveying matrix, so that the express sorting conveying system is also called a matrix express sorting conveying system. For traditional vertical transportation line, in whole express delivery letter sorting process, the conveyer belt of a plurality of conveyers needs to remain running state throughout, conveys the fast forward of the spout landing of being connected on the horizontal letter sorting line, and generally keeps fixed functioning speed to convey, however, do not have the express delivery to need conveying or a small amount of express delivery to need conveying on many times conveying equipment, lead to the motor to be in idle state or high-speed running state for a long time, very big extravagant the running energy consumption of motor for the power consumption cost of express delivery logistics enterprise spends high. Aiming at the problems, the embodiment of the invention aims at the improvement of the longitudinal conveying line to obtain the express delivery conveying system capable of automatically adjusting the conveying speed according to the input express delivery density, the conveying belt can be closed when no express delivery is needed to be conveyed in a certain time, the running speed of the motor is dynamically adjusted according to the express delivery quantity information on the conveying belt when the express delivery quantity is small, the problems that the motor of the conveying belt still needs to run at a high speed when no express delivery or fewer express deliveries are needed on the conveying belt in the traditional express delivery conveying process, and the running energy consumption of the motor is greatly wasted are solved, and the running state of the motor is controlled based on the express delivery density on the conveying belt, so that the energy-saving effect is achieved. Disclosure of Invention The invention provides an express delivery conveying system, an express delivery conveying method, an express delivery conveying device, express delivery conveying equipment and a storage medium, which are used for solving the problem that in the existing express delivery conveying process, a motor of a conveyor belt still needs to run at a high speed when no express delivery or fewer express deliveries exist on the conveyor belt, so that the running energy consumption of the motor is greatly wasted, and different running states of the motor are controlled based on the information of the quantity of express deliveries on the conveyor belt, so that the effects of reducing the energy consumption and saving the energy are achieved. The invention provides an express delivery conveying system, which comprises: The system comprises at least one conveyor, an express delivery output end and at least one express delivery input end of each conveyor, wherein the express delivery output end and the at least one express delivery input end of each conveyor are respectively provided with an infrared se
