System and method for online burning of functional firmware of embedded sub-equipment

Abstract

The invention discloses a system and a method for online burning of function firmware of embedded sub-module equipment. The system comprises multiple sub-module equipment function application firmware supporting the same embedded hardware function, and embedded main equipment with a network and a second data transmission interface, and embedded sub-module equipment with a data transmission interface and a storage medium. The method comprises the following steps that: after detecting the access of an embedded sub-equipment module, the embedded main equipment confirms that the embedded sub-module supports a hardware function type, selects corresponding function firmware through software, and downloads and burns the function firmware to the embedded sub-module equipment. According to the system and method, the same hardware function sub-module can be utilized, different application firmware can be burnt online, the purpose of achieving different product functions is achieved, and the hardware stock-up cost and the equipment management cost of equipment manufacturers can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of embedded firmware function development, in particular to a system and method for online programming of embedded sub-equipment function firmware. Background technique [0002] Embedded hardware devices generally only correspond to one kind of functional firmware. Take the five-way relay output embedded sub-module hardware device as an example. Normally, it is a five-way switch, which only supports the switch control of five-way load lights; if you want to change it to one-way curtain control And three-way light control, or change to two-way curtain control and one-way light control, the embedded sub-module's inherent firmware is not enough, the device must be dismantled, the manufacturer must be used, and the functional firmware must be reprogrammed, which is inefficient. Contents of the invention [0003] The present invention aims to solve the technical problems raised in the background technology, and...

[0002] Embedded hardware devices generally only correspond to one kind of functional firmware. Take the five-way relay output embedded sub-module hardware device as an example. Normally, it is a five-way switch, which only supports the switch control of five-way load lights; if you want to change it to one-way curtain control And three-way light control, or change to two-way curtain control and one-way light control, the embedded sub-module already has inherent firmware, which cannot be satisfied. The device must be dismantled, and the manufacturer must be used to re-burn the functional firmware, which is inefficient.
