The system of whole lock body mainly comprises remote control part and lock control main part.

Remote control part mainly refers to remote control, and remote control is comprised of three parts: by key control and power supply, control indicating section, rolling code generator part and RF radiating portion.Wherein

Key part operating principle is:

This part adopts single-chip microcomputer EM78P372, when there being button " LOCK " or " UNLOCK " while pressing, corresponding S1 or S2 produce the low level pulse signal of a 2S, meanwhile, control the power supply that MOSFET opens rolling code generator and RF part.While having button to press, single-chip microcomputer carries out voltage detecting to battery.If cell voltage, greater than or equal to 2.7V, drives green LED, if lower than 2.7V, drive red alarm, inform that user changes battery.

Rolling code some work principle is:

This part adopts the HCS300 of MICROCHIP company as rolling code generator, and the circuit theory diagrams of its work are as shown in Fig. 8 to Figure 10.

The principle of HCS300 encoder is divided into again following 4 parts:

1, encryption key produces

HCS300, before using, must produce a unique encryption key.Key production process (Fig. 1): produce algorithm through key by works code together with series number and form unique Crypted password, then write EEPROM in sheet.Works code claims again serial codes or manufacturer's code, and length is 64Bit.Each manufacturer is all not identical, and it is for generation of the unique-encryption key corresponding with each encoder.Series number is 28Bit, corresponding to each encoder, can be used as user code.

2,, by former code, encryption key and synchronous code etc. are after KEELOQ algorithm for encryption.Produce the highly confidential rolling code of 32Bit., while transmitting due to the complexity of KEELOQ algorithm and 16 bit synchronization codes, all to upgrade, therefore each transmission code is all completely different with last code at every turn.Only after transmission 2 16 powers, just may repeat, to transmit 10 codes every day, calculate, the time interval is 18 years.

3, EEPROM in sheet

In HCS300 sheet, there are 192Bit(16 * 12) EEPROM, for storage encryption key, sequence number synchronization value and out of Memory, before using HCS300/301 and among using, all need to operate on it.Before using, need it to programme.For regent, only in programming, just can carry out read back check after EEPROM in quite short time, be taboo read states At All Other Times.Among use, read EEPROM information encryption, produce and send code, and upgrade synchronization value.

4, RF radiating portion

The signal that this RF adopts the wireless carrier signal of 433.92HZ frequency that rolling code generator is produced is launched.When data are inputted, RF IC:PT4450 enters duty, and when signal ended, chip enters holding state.

Lock control partly comprises power supply boosting rectifier control, RF reception, buzzer prompting warning, the decoding of single-chip microcomputer rolling code and control and motor drives five parts.

Power supply boosting rectifier control: because the machine is battery-powered, so the processing of need boosting.DC/DC circuit is constant in 3.3V by two whose power supplieds, and the circuit theory diagrams of its work as shown in figure 11.

RF receiving unit: when 433M Hz RF signal comes, this circuit is demodulated to data signal by RF signal and mails to MCU, and RF receiving chip is SYN470R, and the circuit theory diagrams of its work as shown in figure 13.

Motor-drive circuit: motor-drive circuit by according to the order-driven motor forward or reverse of MCU to reach the object of unblanking or locking.In the middle of this circuit, we adopt the method for current detecting to judge whether motor moves to put in place.Utilize the difference of motor electric current when blocking with proper motion, utilize R5 as current detecting.When the electric current of the motor of finding to flow through reaches certain numerical value, judgement motor moves and puts in place.At this moment Single-chip Controlling motor stops, and the circuit theory diagrams of its work as shown in figure 14.

Buzzer: be unlocking signal or upper lock signal for prompting.If lock, send " ticking ", unblank in this way, send " ticking " two sound, the circuit theory diagrams of its work are as shown in figure 15.

Study button: electronic lock main frame, when dispatching from the factory, does not record the ID code of any effective electron key.Now cannot be to being locked into any radio operation of row.Pressed this key for 5 seconds, main frame enters learning state.By the agreement of finishing in advance, to now there being the ID code of the electron key that carries out send action to carry out record, can learn altogether 16 groups of ID codes, after having learnt, by one-touch, exit learning process again, or automatically exit in a period of time.

MCU: the intelligent control center of the machine.Be responsible for the parsing of wireless rolling code, the transmission of corresponding actions instruction, the circuit theory diagrams of its work are as shown in figure 12.Specific as follows:

After powering on, MCU starts working, and mode of operation is normal mode of operation and standy operation mode.Take 1 second as the cycle, standby working time is 980ms, and normal mode of operation is that 20ms. presses 5 seconds as study button, in the process of study, records effective ID code and is kept in MCU.After having learnt, carry out carrying out work by the mode of operation of setting.MCU detects wireless signal to open the mode of 20ms each second.In this 20ms, if there is effective signal to arrive, carry out normal mode of operation until release.The action that MCU unblanks or locks according to this effective signal instruction.Meanwhile, red led is bright.If upper lock signal sends forward instruction to motor-drive circuit.After motor movement puts in place, MCU sends halt instruction, controls buzzer simultaneously and sends " ticking " sound.If unlocking signal issues reversion instruction to motor, after motor movement puts in place, MCU sends halt instruction, and while buzzer sends " ticking " two sound and points out, and red led goes out.The whole action of unblanking or locking completes, and main frame re-starts standby and normal mode of operation.

Intelligent distant control rolling gate door lock 100 described in the utility model; mechanical antitheft lock is combined with electronic intelligence telecontrol engineering; greatly improved the difficulty that rolling gate door lock is unblanked; stopped technical problem of unblanking with destruction lock core; adopt in addition the design of 800mm overlength lock body; greatly improve pick-proof active force, made that rolling-gate is more difficult to be pried open, thereby more effectively, more safely protected user's property and personal safety.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
