Abstract

The invention discloses an input / output passage multiplexing intelligent controller which comprises an input measuring device and a central control device connected with the input measuring device, wherein the input measuring device comprises a signal conversion unit connected with an external signal input passage, and a constant-current source selection unit connected with the signal conversion unit; and the central control device comprises a measuring and sampling unit connected with the signal conversion unit, and a passage configuration unit respectively connected with the signal conversion unit and the constant-current source selection unit. With the adoption of the invention, the same passage can be multiplexed to measure different input signals including current, voltage, thermistance, photoresistance, dry contacts and the like, and passages can be converted manually or automatically to measure signals at different moments, without manually jumping wires. Therefore, the input / output passage multiplexing intelligent controller has the characteristic of convenience in application, flexibility and diversification, high performance price ratio, high efficiency, low alternation cost and wide application range.

Description

technical field [0001] The invention relates to building intelligent monitoring technology, in particular to an input and output channel multiplexing intelligent controller. Background technique [0002] Building automation system is an important part of modern buildings, plays a pivotal role in intelligent buildings, green buildings and low-carbon buildings, and will become one of the basic systems of smart cities. All kinds of mechanical and electrical equipment and facilities in the building are the main control objects of the building automation system. According to the different scales of buildings, the quantity and control requirements of electromechanical equipment and facilities are quite different. Generally, the number of monitoring points in the building automation system is about 2,000 to 3,000, up to tens of thousands, and they are distributed on every floor and corner of the building. These monitoring points involve the building's power system (high-voltage p...
