Embodiment Construction

[0039] Such as figure 1 As shown, the communication method of the present invention applicable to the AGV communication system of the smart garage, the AGV communication system includes two subsystems: eNodeB base station and UE equipment.

[0040] Among them, the eNodeB base station includes MAC (Access Control Layer) module, QoS (Quality of Service Supervision) module, AMC (Adaptive Modulation and Coding) module, MCS (Optimum Modulation and Coding Strategy) module, PDCCH (Physical Downlink Control Channel), PDSCH ( physical downlink shared channel), RS module (resource scheduler) and RB module (radio resource module). The UE device includes a CQI (Channel Quality Index Calculation) module.

[0041] The eNodeB base station is responsible for multi-user and multi-service scheduling in the entire communication system. In the media access control layer, the MAC module allocates RB modules to each UE device in the access system. The QoS module defines the UE device experience as...

Abstract

The invention discloses a communication method suitable for an intelligent garage AGV communication system in the technical field of intelligent garage interaction. The system comprises an eNodeB base station and UE equipment, and the method comprises the steps that the UE equipment measures a channel quality state and feeds back the channel quality state to the eNodeB base station through a CQI value; and the eNodeB base station selects different coding modes to specify a resource allocation strategy for the UE according to the size of the CQI value, and fills the allocation mask of the RB module. According to the communication method, the defects that in the prior art, the coverage range of the communication technology is small, the delivery time is prolonged and the transmission rate is low in the rapid operation state of the AGV can be effectively overcome, the average throughput of the AGV for information interaction when the change of the intelligent vehicle stock / vehicle taking task amount is large is improved, the packet loss rate is reduced, and meanwhile resource scheduling balance of real-time service flow is achieved.

Description

technical field [0001] The invention relates to the field of intelligent garage interaction technology, in particular to a communication method suitable for an AGV communication system in an intelligent garage. Background technique [0002] The smart garage is a fully automatic garage that incorporates modern intelligent control technology. It has the characteristics of autonomous operation and is the latest research direction in the smart parking industry. The smart garage can realize the automatic transfer of vehicles inside the garage and increase the supply of parking spaces in a limited space. It can adopt the separate access method for people and vehicles, which can significantly improve the environmental protection and convenience of the parking process. It is very suitable for the green, Digital and humanized positioning. [0003] The mobile robot (Automated Guided Vehicle, AGV) is the core component of the smart garage, and its communication system plays an importa...
