Remote controller as shown in Figure 7, when pinning stop key and not putting, press downward swing door key, discharge two buttons, this will wake the single-chip microcomputer in the ATMEGA88 of sleep pattern up simultaneously again, and it will radio to alarm opening divide-shut brake order by SI4432 wireless module, and the address that adds oneself in this wireless data packet, complete after order transmission, ATMEGA88 single-chip microcomputer will enter sleep pattern, to save electric weight.
Alarm as shown in Fig. 4,6, ATMEGA88 single-chip microcomputer has received the wireless command from remote controller by SI4432 wireless module, whether it is correct by inspection address wherein, whether order kind belongs to oneself carries out, after this checking, alarm is opened electronic divide-shut brake order by execution: ATMEGA88 single-chip microcomputer will be opened relay, this makes the divide-shut brake driving clutch of mechanical body push being connected of clutch gear and drive motors output shaft aside, now, internal-gear is just free to rotate, realizes manual-operated emergent and opens the door.After from 10 seconds of open relay, ATMEGA88 single-chip microcomputer is by closed relay, and divide-shut brake driving clutch device passes through spring reset.So, completed whole function course.
Below by process and the principle of explanation switch gate.Remote controller as shown in Figure 7, press downward swing door key, this will wake the single-chip microcomputer in the ATMEGA88 of sleep pattern up, it detects the key that all opens the door and is pressed, to the order of opening the door be radioed to main frame by SI4432 wireless module, and add the address of oneself in this wireless data packet, complete after order transmission, ATMEGA88 single-chip microcomputer will enter sleep pattern, to save electric weight.
Main frame as shown in Figure 8, STM32 single-chip microcomputer has received by SI4432 wireless module the wireless data that remote controller sends, it will check that whether address is wherein correct, whether order kind belongs to own execution, and after verifying by this, STM32 single-chip microcomputer is by the execution order of opening the door:
The first step, main frame checks the current rolling door position in software program, if arrived maximum, opens the door highly, represent can to complete order and to exit again to upward-acting door, otherwise, continue to carry out next step.
Second step, main frame, by address and the SI4432 wireless module of alarm, is given an order to alarm, allows alarm start to calculate stroke.Alarm as shown in Figure 6, ATMEGA88 single-chip microcomputer utilizes SI4432 wireless module to receive this wireless data, and check address wherein and order kind, after checking, ATMEGA88 single-chip microcomputer will start to detect the signal of telecommunication number producing in Hall element, and each signal of telecommunication has rotated a circle by the drive motors in the mechanical body representing as shown in Figure 1.
The 3rd step, main frame is opened relay A as shown in Figure 7, closed relay B, the drive motors of mechanical body has just obtained forward operating voltage and has started forward, and rotation will, by driving gear set transmission to internal-gear, so, just drive the unlatching of rolling door.
The 4th step; the STM32 single-chip microcomputer of main frame will be monitored current of electric; if this current value is greater than the maximum pull-up current of the motor of setting; illustrate that rolling door has run into obstruction or top; need to stop at once with protection system; and main frame is also monitored the wireless messages from alarm by SI4432 wireless module, whether confirmation rolling door has arrived the maximum of setting is opened the door highly.
The 5th step, when the maximum of rolling door arrival setting is opened the door height, the electric machine rotation number of turns has also reached the setting value of alarm, and ATMEGA88 single-chip microcomputer will send information to main frame by SI4432 wireless module, notice rolling door has arrived maximum and has opened the door highly, need to stop at once motor.The 5th step, main frame has received after the wireless messages of alarm, and closed relay A and relay B are powered to stop motor, and preserve current rolling door position, for next operation, use, so, the drive motors of mechanical body will lose power supply and supplies with and stop operating.By above step, completed the process of opening the door.
The principle of closing the door and stopping is the same, just presses remote controller close the door key or stop key as shown in Figure 5.
Below by the course of work of explanation warning function.
When rolling door is not normally pulled by mechanical body, but pull by force or rock by external force, to cause that the alarm being contained on roller shutter door-hinge rocks, wherein piezoelectric ceramics also will rock, piezoelectric ceramics is a kind ofly mechanical energy can be converted into the physical material of electric energy, so ATMEGA88 single-chip microcomputer just can detect the signal of telecommunication on piezoelectric ceramics, and rock more severely, the voltage peak producing is larger.When warning threshold that this signal of telecommunication serious offense is set, alarm is with regard to the warning of reporting to the police of long time of alarm loudspeaker, and this information exchange crossed to wireless signal and notify to main frame.
Can pin remote controller pairing key as shown in Figure 7 does not put, press the key of closing the door, discharge again two keys simultaneously, remote controller just sends and cuts out warning function order to alarm by SI4432 wireless module, after receiving, alarm closes by alarm detection, so, even if how rolling door rocks, can not produce loudspeaker warning.In addition, can pin remote controller pairing key as shown in Figure 7 and not put, press the key that opens the door, then discharge two keys simultaneously, remote controller is just sent and is opened warning function order to alarm by SI4432 wireless module, and so, warning function is resumed work again.
