Time channel preemption method and device and computer storage medium

The invention provides a time channel preemption method and device and a computer storage medium. The time channel preemption method is applied to a collector, and the time channel preemption method comprises the following steps: obtaining the size of a to-be-transmitted data packet and a real-time transmission rate; judging whether the transmission of the to-be-transmitted data packet can be completed within the use time of the own time channel; if not, sending an occupancy request instruction to the gateway, so that the gateway returns a response packet containing an occupancy mark according to the occupancy request instruction; and continuing to transmit the to-be-transmitted data packet based on the occupancy mark until the transmission is completed or the occupancy mark is changed. Through the above mode, according to the time channel preemption method provided by the invention, the service time of the time channel occupying other collectors is applied to the gateway, so that the communication efficiency
