The driving unit of mesh equivalent number.
Referring to fig. 2, the driving device of the multi-online air-conditioning system includes: a main control unit 21, and in system
Unit number equivalent number driving unit 22.
The main control unit 21 includes rectifier.By above-mentioned rectifier, the main control unit can be by external friendship
Galvanic electricity is converted to direct current.After converting alternating current to direct current, the main control unit can be to the multi-gang air-conditioner
Each unit in system carries out direct current supply.
The driving unit is for driving the various parts of its affiliated unit to operate.Particularly, the driving unit is used for
The large power assemblies such as compressor, the fan in its affiliated unit are driven to operate.It should be noted that in these large power assemblies
In, it not only may include DC load, but also may include AC load.
Reducing the exchange of main control unit itself by the main control unit in system and by way of driving unit distinguishes
Circuit, that is, reduce the number of the AC load of main control unit.This is beneficial to the EMC performance for improving complete machine.Moreover, adopting
Direct current supply is carried out with the component that a main control unit is the unit in system, in this way, other units only need not be in system
It is equipped with Switching Power Supply, thus reduces the quantity of Switching Power Supply.
Each unit is equipped with a driving unit in system, therefore, machine in the number and system of the driving unit
The number of group is equal.Moreover, the driving unit drives corresponding component under the control of the control chip of its affiliated unit.This
It is meant that the driving unit needs are directly or indirectly electrically connected with the control chip of its affiliated unit, to keep mutual
Between communication.Preferably, pass through universal asynchronous receiving-transmitting transmitter between the driving unit and corresponding control chip
(Universal asynchronous receive r/transmitter, UART) communication chip and keep communicating to connect.
The present embodiment is by being arranged a unique main control unit, and from the main control unit, into system, all units are carried out
Direct current supply reuses respective driving unit in each unit and the component of each unit is driven to operate, to reduce system
The quantity of interior Switching Power Supply, and improve the EMC performance of complete machine.
