Elevator control system program upgrading method, elevator control system and elevator device

Abstract

The embodiment of the invention relates to the field of elevator devices, and discloses an elevator control system program upgrading method, an elevator control system and an elevator device. In thisinvention, the method is characterized in that a program in which the elevator control system can upgrade the target sub-module in a forwarding manner, maintainers only need to operate in the vicinityof the elevator control system during the upgrade process, so that the operation is easy; based on the stored upgrade flags, the elevator control system can verify the integrity of the application program by using the bootstrap to determine whether or not to execute the application program, and then burns and upgrades the application program to avoid the unintended consequences of continued execution of the application due to accidental interruptions or application corruption during the previous upgrade.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of elevator equipment, and in particular to a program upgrade method for an elevator control system, the elevator control system, and the elevator equipment. Background technique [0002] In addition to the main board, the elevator controller and the upper computer, the elevator control system usually includes a drive controller, a door machine controller, a car top controller, a car controller, an outbound call display board, a voice announcer, a weighing Modules and other sub-modules, each sub-module is often distributed in different places, or places that are difficult to access. [0003] In the process of elevator equipment maintenance, it is often necessary to upgrade the program of the sub-module due to loopholes in the software itself or new requirements put forward by the customer. The programming device corresponding to the chip upgrades the sub-module. [0004] But the i...

AI Technical Summary

Problems solved by technology

[0005] 1. It is inconvenient for maintenance personnel to operate, especially to upgrade the outbound call display board, which is equipped on every floor, and the maintenance personnel are time-consuming and labor-intensive.

[0006] 2. When the upgrade process is unexpectedly interrupted, such as power failure, unexpected consequences may occur when the power is turned on again to execute the incomplete program, especially for power device control modules such as drive controllers.
