EIB bus access control unit

Abstract

The invention discloses an EIB bus access control unit which comprises an EIB bus interface unit, an EIB protocol resolution unit and a working power supply unit, wherein the EIB bus interface unit is used for being connected with an EIB bus; the EIB protocol resolution unit is used for encapsulating and resolving EIB protocol as well as receiving and sending data; the working power supply unit is used for power supply conversion; the EIB bus interface unit and the EIB protocol resolution unit are connected with each other and used for two-way data transmission; an output end of the EIB bus interface unit is connected with an input end of the working power supply unit; and an output end of the working power supply unit is connected with an input end of the EIB protocol resolution unit. The EIB bus access control unit is simple and practical, small in volume and low in cost; after a modularized EIB general standard communication module is formed, the development of EIB products aiming at different using functions can become simple and rapid, the launch time of the product can be shortened, and the heavy labor for repeated development can be lightened; furthermore, the development cost is saved. As the EIB standard communication module, the EIB bus access control unit can be widely applied to EIB bus products.

Description

technical field [0001] The invention relates to building electrical and intelligent network technology, in particular to an EIB bus access control unit. Background technique [0002] At present, the EIB bus standard has been included in the national standard GB / Z 20965-2007, but the domestic research on the EIB protocol is still in its infancy, and the communication module based on the EIB communication standard is blank. It uses ready-made EIB bus access units of some large foreign companies for secondary development. The core technology has no independent intellectual property rights, and the key technology and production costs are restricted by foreign manufacturers, and the cost is very high. Because the secondary development must be carried out on the EIB bus products of foreign special-purpose manufacturers, the technical level and production cost of EIB bus products are all subject to foreign manufacturers. The development costs are high, the technical level of indepe...

Problems solved by technology

[0002] At present, the EIB bus standard has been included in the national standard GB / Z 20965-2007, but the domestic research on the EIB protocol is still in its infancy, and the communication module based on the EIB communication standard is blank. It uses ready-made EIB bus access units of some large foreign companies for secondary development. The core technology has no independent intellectual property rights. The key technology and production costs are restricted by foreign manufacturers, and the cost is very high.

Because the secondary development must be carried out on the EIB bus products of foreign special-purpose manufacturers, the technical level and production cost of EIB bus products are all subject to foreign manufacturers. The development costs are high, the technical level of independent intellectual property rights is low, the price is expensive, and product competition The power is poor, which is not conducive to the promotion and use of EIB bus products, resulting in a great limitation in the scope of use, which seriously restricts the development of domestic smart home technology systems
