Problems solved by technology

[0004] The invention provides a blocking control method for rolling shutter doors that adapts to changes in grease, which can solve the problem that when the temperature is low, the lubricating grease of the motor gear freezes, and the operating current of the motor increases sharply, which causes the rolling shutter door to encounter blocking by mistake, resulting in difficulty in closing the door. At the same time, it provides a rolling door resistance control system that adapts to the change of grease, which ensures the smooth operation of the rolling door in cold conditions and avoids affecting its safety.

Embodiment Construction

[0023] The invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0024] Such as figure 1 A resistance control method for a rolling door that adapts to grease changes is shown, including the following steps:

[0025] When closing the door, if the frozen lubricating grease is not thawed within 5 seconds of motor operation, and the motor current is much higher than the normal door closing current, the motor will stop immediately, and then reverse upward to the upper limit;

[0026] Within 2 seconds after the rolling door runs reversely to the upper limit, if the user closes the door again, within 5 seconds of starting to close the door, the controller will turn off the blocking function and the door will go down normally;

[0027] When closing the door, after the motor runs for more than 5 seconds, the lubricating grease begins to thaw slowly under the action of friction. If the rolling shutter door encounters resistance at...

Abstract

The invention provides a meet resistance control method and a control system of a roller shutter door capable of adapting grease changing. Within a certain time after a motor starts working, if a controller receives a signal within a special period of time after meeting resistance and rebounding to an upper limit position, the meeting resistance and rebounding function is turned off. After the motor starts working for more than a certain time, the electric current reference value is increased to run again after meeting resistance and rebounding. The device can solve the problems that when thetemperature is lower, the motor gear lubricating grease is frozen, the running current of the motor is rapidly increased, and the roller shutter door mistakenly meet resistance to cause the difficultyof closing.

Description

technical field [0001] The invention relates to the field of rolling door production, in particular to a method and system for controlling resistance of a rolling door that adapts to oil changes. Background technique [0002] The rolling shutter door is a series of multi-joint movable door pieces. In a fixed slideway, the upper and lower doors are rotated around the scroll above the door. It is widely used in shops, warehouses, etc. Rolling shutter doors are large in size and quality, and most of them are electric. Therefore, not only need to have sufficient anti-theft performance, but also need to consider operability and safety to avoid poor operation or failure, and avoid damage to the people and objects under the door. [0003] At present, many electric rolling shutters are equipped with the function of encountering resistance. The most common way to realize it is to realize the resistance by setting the detection resistance switch and detecting the motor current. The m...
