Description

솔레노이드 래칭밸브 음양반전 구동회로{omitted}Solenoid Latching Valve Yin-Yang Inverting Driving Circuit

신호전류의 입력에 따라 직류전원의 극성을 서로 반전출력하게 하므로서 주로 직류전동기를 정, 역회전 시키는데 많이 사용되는 H브릿지회로는 (도 2) 에 도시된바와 같이 Q1과 Q4를 도통시키거나 Q2와 Q3을 도통시키는 방법으로 전원의 극성을 반전 출력시키는 것으로서, 신호전류를 Q1과 Q4의 베이스에 가하면 정 방향으로 직류전원이 출력되고, 신호전류를 Q2와 Q3의 베이스에 가하면 역방향으로 직류전원이 출력되며, 신호전류를 차단하여야 출력단의 전원이 차단되는 방법이므로 신호출력단과 입력단이 정, 역방향 따로 각 1 개씩 구성되어야 한다.The H-bridge circuit, which is mainly used to directly and reversely rotate the DC motors by inverting the polarity of the DC power supply according to the input of the signal current, conducts Q1 and Q4 or conducts Q2 and Q2 as shown in FIG. Inverting the polarity of the power supply by conducting Q3 conducts the DC power in the forward direction when the signal current is applied to the bases of Q1 and Q4. The DC power is output in the reverse direction when the signal current is applied to the bases of Q2 and Q3. The signal output terminal and the input terminal must be configured separately from the forward and reverse directions.

이 회로는 자동화기기의 직류전동기를 정, 역방향으로 구동 시키는데 광범위 하게 사용하는 기본회로이나, 솔레노이드 래칭밸브를 구동시키는 반전출력회로 로는 여러 가지로 불편한 점이 많은 실정이다.This circuit is a basic circuit widely used to drive the DC motor of the automation equipment in the forward and reverse directions, but there are many inconveniences to the inverted output circuit for driving the solenoid latching valve.

주택난방 설비 분야중 전자회로Electronic circuits in the field of residential heating equipment

솔레노이드 래칭밸브는, 솔레노이드 래칭밸브의 솔레노이드 코일에 직류전원 을 가하는 방향에 따라 밸브가 열리거나 닫히는(솔레노이드 래칭밸브 코일에 ON작동시의 직류전원과 반대방향의 직류전원을 가하면 OFF됨)데, 0.1초간 전원을 가하여 솔레노이드 래칭밸브가 작동을 한 즉시 전원을 차단하더라도 솔레노이드 래칭밸브 코일에 반대 방향으로 직류 전원을 가해주기 까지는 밸브가 ON 혹은 OFF 상태를 계속 유지하고 있는 것이 솔레노이드 래칭밸브이다.The solenoid latching valve is opened or closed according to the direction of applying DC power to the solenoid coil of the solenoid latching valve (it is turned off when DC power in the opposite direction to the DC power in the ON operation is applied to the solenoid latching valve coil). The solenoid latching valve maintains the ON or OFF state until the DC power is applied in the opposite direction to the solenoid latching valve coil even if the power is cut off immediately after the solenoid latching valve is activated by applying power for a second.

솔레노이드 래칭밸브를 H브릿지회로로 구동한다면 동작신호 출력단이 2개가 필요하며 동작신호를 0.1초간 출력하고 즉시 차단하여야 하므로 마이컴을 사용 한 회로를 구성하여야 한다.If the solenoid latching valve is operated by H bridge circuit, two operation signal output stages are required, and the operation signal should be output for 0.1 second and cut off immediately.

그리고 솔레노이드 래칭밸브의 구동출력전원은 0.1초만 출력하고 즉시 차단 하여야 하는데 솔레노이드 래칭밸브의 현 동작상태를 표시하기 위해서는 표시장치(LED등)에는 계속 전원이 가해지도록 솔레노이드 래칭밸브의 동작상태표시 인디케이터 구동회로를 별도로 구성하여야 하는 것도 부담이 된다.And the driving output power of solenoid latching valve should be output only 0.1 second and shut off immediately.In order to display the current operation status of solenoid latching valve, the indicator display circuit of solenoid latching valve is operated so that power is continuously applied to the display device (LED). It is also a burden to be configured separately.

솔레노이드 래칭밸브의 솔레노이드 코일단자에 +, - 직류전류를 정방향으로 입력하면 솔레노이드 래칭밸브가 열리고, 솔레노이드 래칭밸브의 솔레노이드 코일단자에 직류전류를 역방향(정방향의 반대방향)으로 입력하면 솔레노이드 래칭밸브가 닫히는 동작을 하는바, 솔레노이드 밸브코일에 직류전원을 계속 입력하면 솔레노이드 래칭밸브의 솔레노이드 코일에 과전류가 흘러서 솔레노이드 코일이 손상되므로 솔레노이드 래칭밸브가 작동을 한 즉시 솔레노이드 래칭밸브의 솔레노이드 코일단자에 흐르는 직류전류를 차단해 주어야 하며, 현재의 솔레노이드 래칭밸브의 동작상태를 표시하는 인디케이터 회로도 구성하여야 한다.Solenoid latching valve opens when +,-DC current is input to solenoid coil terminal of solenoid latching valve in the forward direction, and solenoid latching valve is closed If the DC power is continuously input to the solenoid valve coil, the overcurrent flows to the solenoid coil of the solenoid latching valve, and the solenoid coil is damaged. In addition, an indicator circuit indicating the operating status of the current solenoid latching valve is to be provided.

그래서 각방 개별난방장치(각 방마다 별도로 난방온도를 자동으로 조절하는 난방조절장치)에서 각 방과 같은 갯수의 전동밸브를 난방분배기에 설치하여야 하는데, 그 전동밸브를 솔레노이드 래칭밸브로 사용하기 위해서는 솔레노이드 래칭밸브 1개마다 1개씩 구동회로를 탑재하여야 하는바, 이것을 H 브릿지회로로 구성하면 비용이 많이 소요되는 단점이 있어서, 이것을 간단하고 경제적으로 구성하고자 하는 것이다.Therefore, in each individual heating device (heating control device that automatically adjusts the heating temperature separately in each room), the same number of electric valves as each room should be installed in the heating distributor.In order to use the electric valve as a solenoid latching valve, a solenoid latching valve Since one drive circuit should be mounted for each one, the H bridge circuit has a disadvantage in that it takes a lot of cost, and this is intended to be simple and economical.

본 발명과 같이 양 전원을 사용하여 트랜지스터를 구동하는 회로를 사용하면 신호입력단 하나로 반전회로가 구성되므로, 마이컴 등의 신호출력 포트가 반으로 줄어들게 되는 효과까지 있어 여러개의 구동회로가 필요한 각 방 개별난방장치의 전동밸브 구동장치에 적용할 경우, 아주 경제적으로 제작할 수 있는 효과가 있다.When using a circuit for driving a transistor using both power sources as in the present invention, since an inverting circuit is configured as a signal input terminal, the signal output port such as a microcomputer is reduced by half, so that each heating circuit requires multiple driving circuits. When applied to the electric valve drive of the device, there is an effect that can be manufactured very economically.

본 발명은 도면 2의 회로도에 도시된바와 같이 양 전원회로를 구성하고, 솔레노이드 래칭밸브의 구동전류 출력점을 Q1의 에미터와 Q2의 콜렉터 사이에서 인출하고 공통선(COM)은 전원트랜스의 중간탭(V+에 대해서는 - 점, V-에 대해서는 + 점)에 연결한다.The present invention constitutes both power supply circuits as shown in the circuit diagram of FIG. 2, draws the drive current output point of the solenoid latching valve between the emitter of Q1 and the collector of Q2, and the common line COM is the middle of the power supply transformer. Connect to the tap (minus point for V +, plus point for V-).

신호전류가 R5를 통하여 Q3의 베이스에 인가되면 Q3의 콜렉터가 도통되고, EC6의 전하가 방전되며 그에 따라서 R1의 2부분과 R2의 2부분 도선이 단락상태로 전환되어 도선상에 전압이 걸리지 않게 된다.When the signal current is applied to the base of Q3 through R5, the collector of Q3 conducts, and the charge of EC6 is discharged, so that the two part wires of R1 and the two part wires of R2 are short-circuited so that no voltage is applied to the wires. do.

이 시점에서 Q1의 베이스 전류가 R3을 통하여 EC5 콘덴서로 충전전류가 흐르게 되고, 이에 따라 Q1의 콜렉터가 도통하게 되어 V+ 전원전압이 음양전 원트랜스의 중간탭에 걸리게 된다.At this point, the base current of Q1 flows through R3 to the EC5 capacitor, whereby the collector of Q1 conducts, and the V + power voltage is applied to the middle tap of the negative positive transformer.

Q1의 베이스전류는 EC5 콘덴서가 충전완료 될 때까지만 흐르게 되고, EC5 콘덴서가 충전완료되면 더 이상 Q1의 베이스전류는 흐르지 않게 되어 Q1의 콜렉터가 열리게 되고 V+ 전원전압이 차단된다.The base current of Q1 flows only until the EC5 capacitor is fully charged. When the EC5 capacitor is charged, the base current of Q1 no longer flows, and the collector of Q1 is opened and the V + supply voltage is cut off.

인디케이터 표시장치(LD1)는 공통선이 Q3의 콜렉터에 연결되어있으므로 Q3의 베이스로 신호전류가 흐르는 동안 계속하여 점등하게 되며, 수동SW(menual_sw1:1)을 닫아도 같은 동작을 실행시킬수 있다.Since the indicator display LD1 is connected to the collector of Q3, the common line is continuously turned on while the signal current flows to the base of Q3, and the same operation can be performed by closing the manual SW (menual_sw1: 1).

수동SW(menual_sw1:1)가 열려있는 상태에서 신호전류를 차단하게 되면, R1과 R2를 거쳐서 EC6의 콘덴서에 충전되는 전류가 Q2의 베이스에 인가된다. 위의 경우와 마찬가지로 Q2의 콜렉터는 EC6의 콘덴서에 충전전류가 흐르는 시간동안만 도통되고, 이때에는 음양전원 트랜스 중간탭의 +전원전압이 Q2의 콜렉터를 도통하여 V-으로 전원전압이 걸리게 되어 아까와는 반대방향으로 직류전원이 부하(valve)에 인가되는 것이다.If the signal current is interrupted while the manual SW (menual_sw1: 1) is open, the current charged to the capacitor of the EC6 through R1 and R2 is applied to the base of Q2. As in the case above, the collector of Q2 conducts only during the time when charging current flows to the capacitor of EC6. In this case, the positive supply voltage of the negative tap of the positive and negative power transformer conducts the collector of Q2, and the supply voltage is applied to V-. DC power is applied to the valve in the opposite direction to.
