Abstract
Description
The present invention relates to a control device sharing a communication line with a driving voltage supply line, and more particularly, to a control device that receives driving voltage through a voltage supply line connected to a predetermined electric device, Quot; control device sharing a communication line with a driving voltage supply line "
In manufacturing and installing and using electric devices and control devices connected thereto, it is general that electric devices and control devices are provided with respective independent and independent electric power and communication lines for mutual communication (refer to Patent Application No. 10- 2005-0073780, entitled "Power Device Wire Communication Control Device")
For example, assume that an electric machine A is supplied with an AC voltage of 220 V through an electric wiring and operates with the driving voltage. In the case of a controller that controls the electric machine A in conjunction with the electric machine A, A separate communication line (2 lines) shall be provided for controlling the communication between the A electrical equipment and the control unit, as well as the use of the AC voltage separately or incorporating an independent DC voltage source.
Therefore, when the A electric device and the control device for controlling it are interlocked, at least four electric wires are required for the control device apart from the A electric device.
That is, a two-wire communication line and two-wire (or three-wire: ground line) driving voltage lines are required.
Particularly, when an electric device is installed in an assembly building such as a building, an office or an apartment, and a control device for controlling the electric device is to be installed together with a building or the like, it is inconvenient for the operator to connect the driving voltage line and the communication line separately. There is a problem that the economic burden due to the individual installation work and the additional input of the materials is transferred to those who purchase it.
That is, in the case of electric apparatuses and control apparatuses that are mutually controlled by the existing wire communication method, each of the apparatuses must have a built-in rectifying circuit, a smoothing circuit, and a voltage regulator, which convert AC voltage to DC voltage, The communication IC and the peripheral circuit for the communication are also designed on both sides.
Therefore, a power supply line of two lines and a communication line of two lines or more are required, which increases the cost of the communication equipment and increases construction cost due to construction.
The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide an electric device and a control device interlocked therewith, which are two devices capable of mutual communication, in which a driving voltage required for a control device is supplied from an electric device to a control device, And more particularly to a control device sharing a communication line with a driving voltage supply line capable of reusing the driving voltage supply line in transmitting a predetermined control signal as a communication signal from the control device to the electric device.

In the first embodiment according to the present invention, a high level voltage of a predetermined level is supplied to the control device in the electric device, the second electric wire is a ground level voltage, And transmits a predetermined pulse signal generated by interrupting a current to the ground level with the level voltage as the communication signal to the electric device.
A second embodiment for realizing the technical idea of the present invention is a control device which is connected to an electric device and connected to first and second electric wires and transmits a predetermined communication signal for controlling the electric device to the first electric wire , The first and second electric wires are used as a driving voltage supply line of the control device and a communication signal transmitted from the control device to the electric device is transmitted through the first electric wire to control the electric device, The device supplies a high level voltage through the first wire and a ground level voltage through the second wire; Wherein the first wire and the second wire are interconnected by a pull-down transistor controlled by the control device, the communication signal being such that when the pull-down transistor is turned on by the control device, And is a pulse signal generated as the voltage drops to the ground level voltage of the second electric wire.
The control unit may further include a signal input unit and a control unit for receiving a signal input through the signal input unit, wherein the control unit controls the signal input unit and the signal input unit in response to the signal input through the signal input unit And a signal for selectively turning on the pull-down transistor is output.
The following advantages are obtained when the control device sharing the communication line with the driving voltage supply line according to the present invention is used.
1. Application of the present invention simplifies the construction for the existing electrical connection and communication control and enables communication control with only two wires, thereby reducing wiring cost, incidental material cost, and construction cost.
2. It is possible to simplify the construction of the control device which does not use the communication-dedicated parts for communication and saves the cost and has no smoothing circuit, so that the circuit design and the product design can be performed with the minimum size.
