The utlity model has following advantage and beneficial effect: the utility model can make the operator in 80 meters scope, is not subjected to the influence of obstruction, by pressing a plurality of button input passwords on the transmitting set, single-chip microcomputer is carried out remote control; The single-chip microcomputer that receives code signal can carry out intelligent distinguishing to password, if password is correct, then lock is opened; Otherwise, if 3 password mistakes will be carried out onsite alarming and pass through the mobile phone dialing alarm call.
1., the signal of transmitting set emission is the radio signal that has address code and numeric data code coding the utlity model has the double insurance function:, in receiving circuit, have decoder module and the control module supporting, this radio intelligent lock can not controlled by other transmitter with transmitter.2., the single-chip microcomputer that receives code signal has the intelligent distinguishing function, even the robber has taken " key ", also lock can't be opened.
Description of drawings:
Fig. 1 is the general structure schematic diagram of this device.
Fig. 2 is a transmitting set structural representation of the present utility model.
Fig. 3 is a wireless transmitter circuits schematic diagram of the present utility model.
Fig. 4 is that wireless signal of the present utility model receives and the intelligence control circuit schematic diagram.
The specific embodiment:
Be described further below in conjunction with the principle and the structure of accompanying drawing the radio intelligent lock that the utility model proposes.
Fig. 1 is the general structure schematic diagram of this device, comprises the transmitting set I that has transmitter module and radio coding, and its emission has the radio modulation signal II that is made up of address code, numeric data code, synchronous code; The radio receiver circuit and the single-chip microcomputer intelligence control circuit III that are used for received signal (having receiver module, decoder module and control module); Controlled electrical equipment IV.User's held radio transmitter, with radio system in 80 meters the scope, in case pressing each button sends radio signal, radio system III can handle this signal collection, and one group of password forming by each button that the single-chip microcomputer intelligence control circuit sends the user carries out intelligent decision, if password is correct, then the electric control lock in the controlled electrical equipment is opened, if 3 mistakes appear in password, then refuse the signal of transmitter and start that alarm in the controlled electrical equipment carries out onsite alarming and by the mobile phone dialing alarm call.
Fig. 2 is a transmitting set structural representation of the present utility model, and A, B, C, D are four buttons of transmitter.
Fig. 3 is a wireless transmitter circuits schematic diagram of the present utility model.Operating principle of the present utility model is: when the user did not press the button of Fig. 2, coding chip PT2262 did not connect power supply, and its 17 pin is a low level, the high frequency transmission circuit failure of oscillations of inner 315MHz; When the user presses any one button among A, B, C, the D, coding chip PT2262 gets electric work, its the 17th pin is exported modulated serial data signal, when 17 pin are between high period, its inner high frequency transmission circuit starting of oscillation is also launched the high-frequency signal of constant amplitude, so high frequency transmission circuit is controlled by the data signal of the 17 pin output of coding chip IC fully, thereby high-frequency circuit is finished amplitude keying (ASK) modulation, be equivalent to modulation degree and be 100% amplitude modulation.The 1st～8 pin of coding chip PT2262 is the address setting pin, there are three kinds of states available: unsettled, connect positive supply, three kinds of states of ground connection, 38 powers are 6561, so the geocoding nonrepeatability is 6561 groups, the geocoding pairing of decoding chip PT2272 in it and the radio system could be used, thus mutual interference can avoid adjacent user to use simultaneously effectively the time.
In the accompanying drawing 4, receiver module among the radio system figure, the radio signal of receiving of being delivered to by transmitting set is amplified, detection, after the demodulation process, the square-wave signal of 1 pin output after demodulation from integrated package LM358, it enters from data-signal input 14 pin of decoding chip PT2272 again, its address code is relatively checked through twice, after decoding is effectively confirmed, at its VT pin (17 pin) output high level, meanwhile corresponding data pin (10,11,12,13 pin) also export high level, thereby by the singlechip CPU corresponding pin (3 of four not gates to AT89S52,4,7,8 pin) input low level, the intelligent control program of single-chip microcomputer operation can be organized level to this and carry out intelligent decision, and from 10,11,16,17 outputs are corresponding high, low level, automatically control is unblanked or is reported to the police and call.
18,19 pin of AT89S52 are by the work clock of outside electric capacity, the crystal oscillator circuit formation single-chip microcomputer inner with it, and operating frequency is 12M.
31 pin of AT89S52 connect high level, carry out the program of ROM in the sheet when making single-chip microcomputer work.
The source program of single-chip microcomputer performing a programme of the present utility model adopts C programmer to design, and can pass through to revise in the source program before burning/recording chip: if (k_count==0x0C)
{
sum＝sum+1；
if(k1_count＝＝0x01
&&k2_count＝＝0x04
&&k3_count＝＝0x00
&&k4_count＝＝0x07)
}
In content, the password that change is provided with; The numeral of k_count is big more, and the confidentiality of password is strong more, should note in modification: the digital sum of k1_count, k2_count, k2_count, k4_counk will equal the value of k_count.
