The chain type electric window opener is mainly applied to opening and closing of windows. With the continuous progress of society and the rapid development of building technology, the national requirements on fire protection systems are correspondingly improved due to the protection of human life and health, and the fire protection system originally only saves fire and is now preventive fire protection to attract more and more attention of people. Since 90% of the victims of almost all fires are killed by smoke toxicity and suffocation, the chain type electric window opener is an indispensable part in the electric natural smoke exhaust window strategy in the market. The control principle of the traditional chain type electric window opener: the on and off of the motor controls the forward and reverse rotation of the micro motor by controlling the forward and reverse conversion of the DC24V voltage through an external controller, so that the extension and retraction of the transmission chain are realized. Thereby realizing the opening and closing of the window. When the chain stroke in the chain type electric window opener is finished, the circuit board detects the locked-rotor current change of the micro motor to realize the power-off principle so as to stop the chain type electric window opener, which is called an overload protection circuit board for short.

However, the overload protection circuit of the traditional chain type electric window opener does not work or works wrongly frequently in the actual use process, when the overload protection circuit board does not work, the current of the micro motor rises rapidly from 0.5A to 3.0A, the overload protection circuit board burns out due to overlarge current, the window cannot be opened or closed, and when the overload protection circuit board works wrongly, the window cannot be opened or closed due to the situation of no power supply. Because of traditional chain formula electric window opener realizes the outage principle through "overload protection circuit board", in the use of traditional chain formula electric window opener is controlled simultaneously to external control ware, can appear concentrating the stall phenomenon, the high peak current impact of short time also can appear in power supply circuit simultaneously, the high peak current impact can also bring the influence to micro motor's life-span to electrical components and the rising current when stalling.
