Synchronous control circuit for fire-fighting electric window opener
The invention discloses a synchronous control circuit for a fire-fighting electric window opener, which comprises a circuit board, the circuit board is connected with a driving circuit, a step-down circuit, an infrared emission receiver and a control chip, the driving circuit and the step-down circuit are in control connection with the control chip, the driving circuit is electrically connected with the step-down circuit, and the infrared emission receiver is in signal connection with the control chip. The device has the beneficial effects that the effect of rotating speed synchronization of multiple groups of motor execution parts is accurately achieved, and the problem of misjudgment of a synchronous controller caused by difference of upper and lower loads when the installation angles of multiple groups of window openers have deviation is effectively solved; the problems that when multiple groups of window opening machine circuits are different, voltage drop exists, motor rotating speeds are different, and the rotating speeds cannot be modulated to be consistent through a current synchronization technology, so that a load window pushed by the window opening machine deforms, glass falls off, and personal safety hazards are caused are effectively solved.
本发明公开一种用于消防电动开窗机的同步控制电路，包括电路板，电路板上连接有驱动电路、降压电路、红外发射接收器、控制芯片，驱动电路、降压电路与控制芯片控制连接，驱动电路与降压电路电连接，红外发射接收器与控制芯片信号连接。有益效果：精准到达多组电机执行部件转速同步的效果，有效解决了多组开窗机本身安装角度存在偏差时，上下负载本身有差异会造成同步控制器误判问题；有效解决了多组开窗机线路不同时存在电压压降，电机转速存在差异，电流同步技术没办法将其转速调制一致易造成开窗机推动的负载窗户变形导致玻璃脱落造成人身安全危害问题。
