Embodiment Construction

[0025] In the embodiment of the present invention, in order to obtain an adjustable-speed motor driver with a wider power range and a smaller power grid impact start at a lower cost, it is considered to use a lower-cost cabinet-mounted inverter with a protection level below IP65 , such as the V20 inverter to control the external variable frequency motor, and in order to achieve AS-I communication, consider using the first interface conversion module such as the AS-I SlimLine module to integrate the DI / DO point of the cabinet-mounted inverter into the AS-I The bus is finally sent to the programmable logic controller PLC for control and feedback. At the same time, add at least one second interface conversion module such as AS-ISlimLine module to collect other I / O signals on site. And in order to improve the protection level, it is considered to adopt the IP65 protection level standard to design the box body that accommodates the cabinet-mounted inverter and the interface convers...

Abstract

The embodiment of the invention discloses a distributed frequency conversion box and a conveying system. The frequency conversion box comprises an in-cabinet mounted frequency converter used for controlling an external variable frequency motor, a first interface conversion module used for performing interface conversion between the in-cabinet mounted frequency converter and an AS-I bus, at least one second interface conversion module used for performing interface conversion between the at least one field sensor and the AS-I bus, and a box body whcih satisfies a protection grade IP65. An interface between the in-cabinet mounted frequency converter and an external power supply, an interface between variable frequency motors, an interface between the AS-I bus and an external AS-I network, and an interface between a second interface conversion module and at least one field sensor are all plug-in type interfaces. According to the technical scheme in the embodiment of the invention, a speed-adjustable motor driver with a wide power range and small power grid impact starting can be realized with low cost.

Description

technical field [0001] The invention relates to the field of logistics conveying equipment, in particular to a distributed frequency conversion box and a conveying system. Background technique [0002] For the sorting system conveyor lines in airports and logistics centers, since the equipment is relatively scattered, the conveyor motors are suitable for machine-side control, and usually require high-protection-level drives and AS-I communication. A solution currently in use is to adopt the following two methods of controlling the conveying motor with a protection level of IP65: 1. Use the distributed frequency converter G110D to control the frequency conversion start of the conveying motor, and the distributed frequency converter G110D integrates AS-I communication . 2. The motor starter M200D is used to control the direct start of the conveying motor, and the motor starter M200D integrates AS-I communication. [0003] However, among the above two methods, the G110D inver...
