Embodiment 1

[0022] Embodiment one: see figure 1 , image 3 , Figure 4 and Figure 5 , the electromagnetic lock is fixed on the ground, and the lower edge of the rolling shutter door is fixed with an iron plate 5 (or an electric mortise lock 19 fixed in the middle and lower part of the door frame close to the ground, and at the same time, there is a slot 18 for matching with the electric mortise lock on the corresponding position on the door panel), The rolling door machine is installed on one side of the reel and closed, and the control chip is installed near the motor or hidden in the box near the wall. The control line of the electromagnetic lock (or electric mortise lock) is connected to the output terminal of the control chip U1 after being connected through the PNP Darlington tube Q1. At the same time, the limit output line of the DC motor is connected to the limit interface on the controller.

Embodiment 2

[0038] Embodiment two: see figure 1 , image 3 , Figure 4 and Figure 5 , the electromagnetic lock is fixed on the ground, and the lower edge of the rolling shutter door is fixed with an iron plate 5 (or an electric mortise lock fixed in the middle and lower part of the door frame close to the ground, and at the same time, there is a slot 18 for matching with the electric mortise lock on the corresponding position on the door panel). When the door is closed to the fast bottom, the magnet 3 fixed on the door panel is close to the lower limit probe 4 (the limit probe can be a Hall switch, reed switch, etc.), at this time the lower limit probe sends out a signal to the lower limit, and the controller After detecting the signal of closing the door to the lower limit position, a signal is sent to control the electric mortise lock 19 to be energized to work, and the "bolt" of the electric mortise lock is inserted into the slot 18 in the door panel, and the door is locked, so that...

Embodiment 3

[0039] Embodiment three: see figure 1 , figure 2 and Figure 5 , the content is basically the same as that of Embodiment 1 or 2, and the similarities will not be repeated. The difference is that an infrared sensing module is provided, that is, infrared directing sensors are installed on both sides of the door frame close to the ground, and the infrared sensors on both sides are respectively installed. The signal line of the through-beam sensor is connected with the input end of the control chip. If there is an obstacle under the door during the process of closing the door, the signal from the transmitter of the infrared probe CON4 will be blocked, and the receiving end of the infrared probe will send out a level signal. After the 4th pin of the microcontroller detects the output signal of the infrared probe , will send a high-level signal to pin 14, drive the relay JD2 to pull in, and the door movement will stop.

Abstract

The invention relates to a remote control electric rolling door direct-current motor control circuit with an automatic locking function. The circuit comprises a singlechip main control module, a door rolling machine action control module, a limit interface, an automatic locking module, a direct-current power supply module and a remote control receiver module, wherein an electric control lock is arranged between the ground and the lower edge of a rolling door; a direct-current door rolling machine limit signal output end is introduced into the limit interface; the electric control lock is connected with the output end of a controller; the controller is connected with the remote control receiver and provided with a remote control transmitter; the door rolling machine of the rolling door is a direct-current motor; the direct-current power supply module comprises a mains supply voltage transformation rectifying circuit and a storage battery; and two power supplies supply power to the direct-current door rolling machine simultaneously. The door can be automatically locked and prevented from being artificially lifted or prized after being closed, so that safety performance is high; and the storage battery is used for supplying power, so that the door rolling machine still can be driven to work when a mains supply is cut off, and the circuit is more convenient to use.

Description

technical field [0001] The invention relates to a rolling shutter door control technology, in particular to a remote control electric rolling door DC motor control circuit with an automatic locking function. Background technique [0002] At present, the known control systems used on the market can realize the remote control electric door opening and closing function, but there are still many shortcomings and defects that have not been resolved. These defects mainly include: [0003] 1. For all electric rolling doors, when the door is closed to the end, due to the soft feature of the door, the door can be lifted from the bottom, thieves can enter, and the safety performance is poor; even some large doors cannot be lifted by hand. It can be pried up with a stick, and people can easily climb in, and the anti-theft safety performance is very poor. This is the known fatal shortcoming of the electric rolling shutter door in the door control industry, but it cannot be solved so f...
