Description

Reeling device

A retracting device, in particular, a retracting device for detecting a motor starting time by detecting a motor current to know a retracting or opening position of a retractor.

According to the present, most of the curtains and doors are opened and closed by the winding method. For the convenience of the user, the curtain and the door of the winding method are connected with the motor and the controller so that the opening and closing can be performed automatically. In the situation where the operator is on site, the operator can use the controller to control the opening, closing and stopping of the curtain or the door. However, even now, even if the operator is not in the scene, there are many ways (such as internet, radio). Automatically adjust the opening or closing position of the curtain or door to save energy, health (appropriate light can be sterilized), safety (can close the door and window when there is squally shower), and can clearly know and control the curtains in order to meet the staff Such a device must have the ability to read the open or closed position of the window or door by opening or closing or partially opening the door (eg, 60% on). In order to let the controller know the opening or closing position of the curtain or the door, most of the following structures are set:

1. A gear set is connected to the curtain or the reel of the door, and the gear set is connected with a mechanical switch, and the gear ratio of the gear set is used to trigger the mechanical switch, so that the controller can know the opening or closing of the curtain or the door. position.

2. The Hall element is mounted on the reel, and when the reel is scrolled, the Hall element detects the rotation of the reel, thereby calculating the opening or closing position of the curtain or the door.

However, the above-mentioned conventional method of detecting the opening or closing has the following defects:

1, the gear set trigger mechanical switch can usually only get two positions of full open or full off If the user is not at the scene, the position of the curtain or the middle stroke of the door cannot be known exactly.

2. Although the Hall element can accurately calculate the position of the intermediate stroke by calculating the opening or closing position, it must be installed on the reel of the curtain or the door, so the installation is very inconvenient and the Hall element is damaged. It is also not easy to disassemble and replace.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of this creation is to use the controller set to calculate the starting time of the motor based on the current generated by the motor when starting the motor, so as to accurately know the retracting or opening position of the retractor.

The secondary purpose of this creation is that the controller unit does not need to be connected to the retractor for ease of use and installation and maintenance, and can be upgraded to open or close with controlled curtains or doors in the easiest way for existing curtains or doors. Or a partially opened smart device.

In order to achieve the above purpose, the creation retracting device is provided with a motor group, the motor group is respectively connected with a controller group and a power group, the motor group is provided with a motor, and the motor is respectively connected with a retractor and a reversing switch, and is replaced. A power switch is connected to the switch. When the controller group activates the power switch of the motor group, the power supply unit supplies the power supply to start the motor, and the controller group detects the current generated by the motor, and the current duration is used as the start of the motor. Time, and then calculate the retracting or opening position of the retractor.

The above-mentioned retracting device, wherein the controller group is provided with a microprocessor for controlling a commutation switch and a power switch of the motor group, and the microprocessor is connected with a current detector for detecting a motor current, and the microprocessor Connect a signal receiver/transmitter that is used to transmit signals and receive control signals from the remote control.

In the above retracting device, the power supply unit has an external power supply, the external power supply is connected to the power supply, and the external power supply is connected to the power switch of the motor unit.

The first picture is a block diagram of the creation.

The second picture is the circuit diagram of this creation.

Please refer to the first figure and the second figure. It can be clearly seen from the figure that the retracting device of the present invention is provided with a motor group 1, and the motor group 1 is respectively connected with the controller group 2 and the power source group 3, wherein: The motor unit 1 is provided with a motor 11 to which the retractor 12 and the reversing switch 13 are respectively connected, and the reversing switch 13 is connected to the power switch 14, and the retractor 12 is opened or closed in a retracting manner. Rolling doors or curtains.

The controller group 2 is provided with a microprocessor 21, and the microprocessor 21 is connected with a current detector 22 and a signal receiving/transmitting unit 23. The microprocessor 21 is connected to the commutation switch 13 of the motor unit 1 and the power switch 14. The control unit 22 is connected to the power switch 14 for connecting the power switch 14 for transmitting signals and receiving the control signals sent by the remote controller 4.

The power pack 3 has an external power source 32, the external power source 32 is connected to a power supply 31, the external power source 32 is connected to the power switch 14 of the motor group 1, and the power supply 31 is connected to the controller group 2 to provide a controller group. 2 required power.

By the way, when the user uses the retracting device for the first time, the microprocessor 21 of the controller group 2 is first set to the learning state, and then the remote controller 4 is used to control the power switch 14 and the reversing switch 13 to make the power pack. The external power supply 32 of 3 supplies the power to start the motor 11, and drives the retractor 12 to perform a complete opening and retracting, allowing the microprocessor 21 to record the motor 11 to fully open the retractor 12 at one time, and a complete reel. The time required for the receiver 12; when the microprocessor 21 records the time required for the motor 11 to fully open and retract the retractor 12, the current detector 22 detects the current generated by the motor 11 due to startup. And the current duration is used as the motor 11 The time 21, therefore, the microprocessor 21 does not start calculating the start time of the motor 11 when the power switch 14 is turned on, but starts to calculate the start time of the motor 11 when the motor 11 starts generating the current, and the power switch 14 can be avoided.
