Body, that is, operate button 1, display 2, single-chip microcomputer 3, power circuit 4, motor and motor-drive circuit 5 and alarm 6,
Being characterized in that for compound puzzle lock, operates the key information collecting part of button digital including one group of collection button correspondence
Digital sensor 7 and one group of pressure sensor of collection key press 8, digital sensor 7 and pressure sensor 8 are arranged at behaviour
Make the lower section of each button of button 0-9, digital sensor 7 is that information reading is completed by way of keyboard poll, and pressure is passed
The pressure value of sensor 8 read be by single-chip microcomputer inside AD sample circuits by programming realization, the model of single-chip microcomputer
STM32F103ZET6;As shown in Figures 2 and 3, numbering is to be compiled on the wire connection single-chip microcomputer 3 of PA0-PA6 in digital sensor 7
Number for PA0-PA6 I/O pins on;As shown in Figure 3 and Figure 5, pressure sensor 8 connects single by the wire that numbering is Y0-Y#
Numbering is PA0-PA7 and the I/O pins of PC0-PC3 on piece machine;Display 2 uses 1602 liquid crystal displays, such as Fig. 3 and Fig. 4 institutes
Show, the I/O pins that numbering on single-chip microcomputer is PE7-PE15 are connected by the parallel data grabbing card of display, for showing related letter
Breath;Power circuit 4 is used for as shown in fig. 6, connecting the pin that all numberings on single-chip microcomputer are VDD by the wire that numbering is 3.3V
Power supply is provided to single-chip microcomputer 3, power circuit 4 includes first order step-down and second level step-down, and first order step-down uses switch voltage-stabilizing
The DC voltage of 30V-7V can be converted into chip LM2596, this chip the voltage of direct current 5V;Second level step-down uses low
The linear voltage-stabilizing circuit AMS1117-3.3V of pressure difference, pure direct current is stablized for being provided to single-chip microcomputer 3;Motor-drive circuit
5 as shown in fig. 7, by numbering be PD7 and the wire of PD6 connect single-chip microcomputer 3 on numbering be PD7 and the I/O pins of PD6 be used for control
Motor processed, motor-drive circuit 5 is an electromagnetic relay for two-way, be equipped with triode and metal-oxide-semiconductor composition can be real
The circuit of existing forward and reverse and stopping action;Alarm 6 is compiled as shown in figure 8, being connected by the wire that numbering is PB6 on single-chip microcomputer 3
Number it is used for alarm during abnormal unlocking for the I/O pins of PB6;As shown in figure 9, by the pin of each VDD in single-chip microcomputer
A upper 0.1UFde electric capacity in parallel filters influence of the noise produced by whole system to single-chip microcomputer.
Hybrid password based on pressure sensor adds collection key press on the basis of being locked in original digital cipher lock
Pressure sensor;Data storage in single-chip microcomputer includes first memory and second memory, and data information memory is in list
In the internal memory of piece machine, ensure that its internal memory does not disappear under first memory energy long-time off-position, second memory is one random
Memory RAM, the data storage carries 6 digit counters and 3 count-up counters, while also carrying 10 time countings
Device, each of which counter has 3 storages single, and first count-up counter in data storage is used for record and is provided with
The number of pressure sensor initiation value, often sets an initiation value for sensor, and count-up counter will add 1, such single-chip microcomputer
On just record Opening pressure password need be input into button number;Second count-up counter sets for recording digital cipher lock
The number of numerical ciphers is put, a numerical ciphers are often set, count-up counter will add 1, just be recorded out on such single-chip microcomputer
Opening digital cipher lock needs to be input into the number of button;3rd count-up counter is used to record the number of times that opener uses button,
Most the summation of first, second two count-up counter record input number of times is stored in digit counter single-chip microcomputer at last, while
If a button is both pressure password and numerical ciphers in the middle of the password of setting, single-chip microcomputer can give tacit consent to defeated by preprogramming
The number of times for entering subtracts one.Digit counter in data storage stores the corresponding number of Opening pressure sensor and starts
Value, time counter is used to record the service condition of coded lock.
After the pressure sensor for needing to set initiation value is set, Opening pressure password is just recorded on single-chip microcomputer to be needed
The number of button is input into, each pressure sensor is provided with default value, and default value is stored in data storage, when certain digit
Code is when being arranged to the element in numerical ciphers group, and default value will disappear failure;Pressure sensor pair below every button
The default value answered is general small both relative to initiation value, but will than the power that normal user applies in input numerical ciphers
Greatly, whether it is an element in numerical ciphers array for the digital of single-chip microcomputer identified input;No matter whether pressure reaches
Initiation value or default value, the 3rd count-up counter can all add 1, when button person is beyond Password Input set in advance on single-chip microcomputer
Number and continue during by other buttons, Single-chip Controlling start alarm equipment alarm self-locking;When re-entering, button is maintained at
Number can be retried repeatedly in the case of being no more than password number set in advance, but if beyond password number set in advance still
Can alarm for opening.When using pressure password, only correctly opened more than or equal to pressure by the power in key mapping when while being applied to
Dynamic value, this particular pressure signal input that pressure sensor will can just be detected to the AD sample circuits inside single-chip microcomputer, AD
The pressure information of input can be converted into pressure value by sample circuit, then be supplied to the single-chip microcomputer, single-chip microcomputer will to receive pressure value
The pressure value for arriving is added, the first pressure value of original programming setting in traversal computer(First pressure value is a pressure limit, and
A non-definite value), the first pressure value of the multiple pressure value sum in-scope searched and receive, then transfer again with this
The second pressure value of one pressure value association(Second pressure value is a fixed number), finally transfer the control being associated with the second pressure value
Processing procedure sequence.Here we do not have and turn on pressure password finding the first pressure value that matches with first pressure value, be because
The pressure summation applied every time to open coded lock is typically different from, so first pressure value can only be a pressure limit,
Finally transfer the control program being associated with second pressure value, be in order in the case of extraneous unnormal unlocking, can be by password
Lock is locked, protects the valuables of user.
