Roller door controller upper limit setting method

A roll-up controller upper and lower limit setting method, especially a controller capable of setting a limit position and a lower limit position on a roll door.

According to the early iron roller door mechanism, due to the lack of safety protection settings, there are many potential risk factors, such as: crushing the person when the roller door is dropped, the motor is idling, the manual power cannot be turned on when the power is off, etc., but with the industry The industry has been actively researching and improving. At present, the safety of the iron roller door has been greatly improved. However, the industry still uses the limit switch or the micro switch as the control element for controlling the stop or the running stroke of the motor in the lift, in other words, it is still detached. The idea of achieving control objectives with hardware components is not neglected, such as the inability to effectively reduce manufacturing costs, the limitations of hardware components, the complexity of circuit design and overall hardware architecture, and the The inconvenience of implementing the change, therefore, the inventor of the present invention invented a control method of the electric rolling door controller in response to the above-mentioned lack of perfection, the control method of the electric rolling door controller has obtained the invention patent of the Republic of China No. I270607 No., but after continuous research and trial work by the inventor of the case, the announcement No. I270607 The technology, when using the roll door for the first time, you must first lower the roll door to the ground and then return to zero to confirm the lower limit. After adjusting to the required upside height by the remote control, confirm it by the remote control, so as to set the upper limit, and below The distance between the limit and the upper limit is used as the roll-up stroke. Therefore, the user must read the manual or set it by a special person during the first operation, which is cumbersome in operation.

The main purpose of the present invention is that the roll door can be installed and connected to the controller. Direct use, and the controller will set the upper limit position and the lower limit position for the user to use.

To achieve the above object, the present invention is provided with a rolling door and a controller for controlling the opening or closing of the rolling door. The controller has a microprocessor and a motor overload detector. When the rolling door is installed and connected to the controller, the user The control signal for opening or closing the roll door can be input, and the roll door motor can be detected by the motor overload detector during the opening or closing process. If the roll door motor is overloaded when it is opened, the roll door motor is immediately stopped. And the position of the roll door is set to the upper limit position at this time. If the roll door motor is overloaded when it is closed, the roll door motor is immediately stopped, and the position of the roll door is set to the lower limit position at this time, thereby making the controller Set the limit position and lower limit position above the roll door.

Referring to the first figure and the second figure, it is clear from the figure that the present invention is provided with a roll door 1 and a controller 2 having a microprocessor 21, a motor overload detector 23 and a stroke.

(205) The motor overload detector 23 continuously detects whether the motor of the roll door 1 is overloaded. When the motor of the roll door 1 is overloaded, it indicates that the roll door 1 is fully opened. At this time, the microprocessor 21 stops the roll immediately. The action of opening the door 1 and performing step (206).

(206) The travel calculator 24 calculates the fully open position of the roll door 1, and the microprocessor 21 sets the position to the upper limit position, and proceeds to step (102).

(208) The microprocessor 21 sets the state of the roll door to the upper limit state, that is, the state in which the roll door 1 is fully opened, and proceeds to step (102).

(209) The motor overload detector 23 continuously detects whether the motor of the roll door 1 is overloaded. If the motor overload detector 23 does not detect that the motor of the roll door 1 is overloaded, then Step (207); if the motor overload detector 23 detects that the motor of the roll door 1 is overloaded, the microprocessor 21 immediately stops the operation of opening the roll door 1, and performs step (210).

(210) The microprocessor 21 compares the position of the roll door 1 with respect to the upper and lower limit reset ranges when the motor of the roll door 1 is overloaded. If yes, step (101) is performed; if not, step (102) is performed.

(301) The microprocessor 21 determines whether the control is to turn off the control signal of the roll door 1, and if so, performs step (302); if not, executes step (102).

(303) The microprocessor 21 drives the roll door 1 to start closing, and the travel calculator 24 continuously calculates the position during the closing of the roll door 1, and proceeds to step (304).

(304) The microprocessor 21 reads the lower limit position. If the lower limit position data is not set, the step (305) is performed; if the microprocessor 21 sets the lower limit position data, the step (308) is performed.

(305) The motor overload detector 23 continuously detects whether the motor of the roll door 1 is overloaded. When the motor of the roll door 1 is overloaded, it indicates that the roll door 1 has been completely closed. At this time, the microprocessor 21 stops the roll immediately. The action of opening the door 1 and performing step (306).

(306) The microprocessor 21 checks if the upper limit position data is set, and if so, proceeds to step (307); if not, proceeds to step (102).

(307) The microprocessor 21 sets the full closing position of the roll door 1 calculated by the stroke calculator 24 to the lower limit position, and proceeds to step (102).

(308) The microprocessor 21 continues to calculate whether the position of the roll door 1 is closed during the closing process of the roll door 1 and whether the lower limit position is reached. If yes, proceed to step (309), and if not, proceed to step (310). .

(309) The microprocessor 21 sets the state of the roll door to the lower limit state, that is, the state in which the roll door 1 is completely closed, and proceeds to step (102).

(310) The motor overload detector 23 continuously detects whether the motor of the roll door 1 is overloaded. If the motor overload detector 23 does not detect that the motor of the roll door 1 is overloaded, proceed to step (308); if the motor is overloaded The detector 23 detects that the motor of the roll door 1 is overloaded, and the microprocessor 21 immediately stops the operation of opening the roll door 1, and proceeds to step (311).

(311) The microprocessor 21 compares the position of the roll door 1 with respect to the upper and lower limit reset ranges when the motor of the roll door 1 is overloaded, and if so, performs step (101); otherwise, proceeds to step (202).

By the way, when the roll door 1 is installed and connected to the controller 2, the user can input the control signal for opening or closing the roll door 1 to make the roll door 1 use the motor overload detector 23 during the opening or closing process. The roller 1 motor is detected, and the upper limit position and the lower limit position are set, so as to avoid the inconvenience that the user must first set the upper limit position and the lower limit position in the prior art.

Furthermore, the present invention further utilizes the upper and lower limit reset ranges to determine the opening and closing positions of the roll door 1, and if the opening and closing positions of the roll door 1 are within the upper and lower limit reset ranges, it represents the opening or closing of the roll door 1. If an error occurs, the upper limit position and the lower limit position are set to be cleared, and when the roll door 1 is closed or opened again, the upper limit position and the lower limit position are reset.
