The garage door in Ji'nan cannot be stopped when it is running. The main reason is that a lot of strong electromagnetic waves are generated when the motor is running, which interferes with the power of the receiving part of the circuit, produces a lot of clutter on the power supply, and makes the remote control distance very close.
1, Ji'nan garage door in the receiving circuit and the main control circuit power and ground add magnetic beads, magnetic ring, inductance and other devices, and add filter capacitance and other filter devices.
2. The installation position of the receiving board and the main control board is far away from the motor.
3, if the receiving circuit and the main control circuit can be shielded, it will have a better effect.
4, adding filter and pulse components on the two poles of the motor, so as to shield the motor as far as possible.
5, the receiving antenna is pulled out with the shielded line, which is a little far away from the motor, so it is beneficial to increase the distance of the remote control.
