As shown in fig. 1, the method for controlling the resistance of the roller shutter door adapting to the change of grease comprises the following steps:
when the door is closed, the frozen lubricating grease is not thawed within 5 seconds of the operation of the motor, the current of the motor is far greater than the normal door closing current, the motor is immediately stopped, and then the motor reversely ascends to the upper limit;
The rolling door reversely runs to the upper limit within 2 seconds, if the user closes the door again, the controller closes the resistance meeting function within 5 seconds after the door is closed, and the door body normally descends;
When the door is closed, after the motor runs for more than 5 seconds, the lubricating grease starts to slowly thaw under the action of friction, at the moment, if the rolling door encounters resistance, the result that the thawing current of the grease is unstable or the actual resistance is met, at the moment, the motor reversely ascends for 2 seconds, then the reference value of the resistance current is increased, the rolling door continues to descend, if no resistance is encountered during the descending process, the rolling door is smoothly closed, if resistance is encountered, the rolling door reversely runs for 2 seconds and then stops running, and at the moment, the resistance current reference value is 0.5 ampere increased for the normal door closing current.
During debugging, the door body runs back and forth at least once between the upper limit position and the lower limit position, the maximum current in the running process is read and selected, the normal working current is set accordingly, the resistance current reference value is determined, and 0.2 ampere is added on the basis of the running current value of the door body to set the normal door closing current of the door body. And within 5 seconds of closing the door, when the detected motor current exceeds one time of the normal door closing current, the motor immediately stops and reversely moves upwards to the upper limit. At the moment, the door body is positioned near the upper limit position, and the damage to the lower personnel and articles can be avoided. And after the rolling door works for a certain time, automatically debugging and updating the normal working current and determining a resistance current reference value.
When the door is closed, the motor operates within 5 seconds when the motor starts to operate, when the detected motor current exceeds one time of the normal door closing current, the motor immediately stops and then reversely ascends to the upper limit, and the alarm gives an alarm if the controller does not receive an operation signal within 5 seconds; the door body stops after rebounding when meeting the resistance, and the alarm gives an alarm.
A resistance meeting control system of a roller shutter door adapting to grease change comprises a single chip microcomputer controller, a remote controller and a driving motor, wherein a current sampling circuit is arranged on the controller, the controller controls the driving motor to rotate forwards, stops and reversely, the driving motor drives a winding drum to rotate through chain transmission, the winding drum drives a door body to move upwards and downwards, and the sampling remote controller controls the door body to move.
Within 5 seconds after the driving motor starts to operate, if the current sampling circuit detects that the current of the descending meeting resistance of the door body exceeds a set value, the set value is one time of the normal door closing current, the controller controls the driving motor to rotate reversely until the door body reaches the upper limit, and the controller receives a descending signal of the door body within 5 seconds, the motor drives the door body to descend and closes the function of rebounding of the meeting resistance for 5 seconds.
After the driving motor works for 5 seconds, the current sampling circuit detects that the working current of the motor exceeds the normal working current value, the controller controls the driving motor to rotate reversely for 2 seconds, then the reference value of the current meeting resistance is increased, the controller controls the driving motor to rotate forwards again, and if the door body meets resistance again, the controller controls the driving motor to rotate reversely for 2 seconds and then stops rotating.
The current in the running process of the motor is monitored through the current sampling circuit and is compared with the normal working current so as to judge whether the rolling door is blocked or not. The normal working current is set during debugging, in the debugging process, the door body runs back and forth between the upper limit and the lower limit once, and the maximum current in the running process is read and selected, so that the normal working current is set and the reference value of the resistance current is determined. In this embodiment, the normal operating current is determined by adding 0.2 ampere to the maximum current, and the reference value of the encountered current when the door body moves downward again after rebounding in a encountered state is the normal operating current plus 0.5 ampere.
After the door body runs for a certain number of times, the normal working current and the resistance meeting current reference value are automatically debugged and updated according to the detected maximum running current of the motor, so that the problems that the resistance meeting function is abnormal and the roller shutter door cannot be normally used due to the change of the motor current caused by various reasons after the door body runs for a period of time are avoided.
