Elevator control board, black box and control function module based on fpga

Abstract

The invention relates to the field of elevator control and discloses an elevator control panel and black box as well as an FPGA (field-programmable gate array) based control function module. The elevator control panel comprises a communication bus circuit, a human-computer interaction circuit, a high-low voltage input and output circuit and the FPGA based control function module, wherein the control function module comprises first and second processors, a communication bus control module, a human-computer interaction control module, a high-low voltage input and output control module and a transducer control module; the first processor is a main control unit and is in communication connection with the second processor, the communication bus control module, the human-computer interaction control module and the high-low voltage input and output control module; the second processor is a drive control unit and is in communication connection with the transducer control module; the communication bus control module is in communication connection with the communication bus circuit; the human-computer interaction control module is in communication connection with the human-computer interaction circuit; the high-low voltage input and output control module is in communication connection with the high-low voltage input and output circuit. An elevator control system is simplified by adopting the elevator control panel.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator control board, a black box and a control function module based on FPGA (FPGA, Field-Programmable Gate Array, Field Programmable Gate Array). Background technique [0002] With the rapid development of social economy, a large number of high-rise buildings emerge, and the role played by elevators in people's daily life is becoming more and more important. In the prior art, the main control unit and the drive control unit are relatively important components in the elevator control system. The main control unit is the core of the elevator control system. It is mainly responsible for the logic control of the elevator operation, coordinating the elevator up and down and call signals, and sending control commands to the drive control unit. The drive control unit is used to control the frequency converter. When receiving the control command from the main control unit, it adju...
