Abstract
This invention relates to a controlling method of ceil phone infrared electric lock, characterized in that it receives the code information sent from the ceil phone through the infrared interface, controlling the open and close of the electrical lock. The infrared ceil phone is the holder of the electrical key, only when the cell phone electrical key is corresponding to the key of the electrical lock it can be opened; the key coding of the electrical lock applies the pseudo-random method to code and control, and the electrical lock applies programmable component to set the key and the widow to receive the infrared key; the infrared cell phone and electrical lock will realize infrared host-host protocol, controlling the open and close of the electrical lock through the code sent by the cell phone. Through said invention, it can realize the management of the mobile communication base station.
Description
Technical field
The invention belongs to a kind of method and controller that utilizes the mobile phone infrared interface to control the electronic lock opening and closing.
Background technology
Utilize the electronic lock opening and closing that many advantages are easily arranged,, can accomplish arbitrary control, but magnetic card or IC-card are special carriers as widely used magnetic card in hotel or IC-card key electronic lock.Still have limitation in the use, as carrying special carrier.Mechanical lock also has similar weak point in the use.As at moving communicating field, communication base station has a very wide distribution, and quantity is many, the main at present method by traditional mechanical lock of the security protection of its facility.Because base station number is too big, the management of key and use are very inconvenient.Enter same door with lock for a specific group object in the different time for another example and also need electronic lock control method more easily.In order to solve an above-mentioned difficult problem, the present invention has been proposed.
Summary of the invention
The object of the present invention is to provide a kind of infrared control method, make and to control opening and closing by the mobile phone infrared interface as specific door locks such as mobile communication base station door locks.Simultaneously, provide a kind of controller that utilizes said method to realize,, improve the safety of protection such as specific occasion such as base station to reduce management and running cost.
The object of the present invention is achieved like this: the infrared electronic lock of mobile phone control method, infrared mobile is as the electronic key holder, the key of infrared mobile electronic key and electronic lock itself could be opened seasonable, the key coding of electronic lock itself adopts the pseudo-random method coding to control, be that electronic lock adopts programming device such as single-chip microcomputer to establish window close and the infrared key of conduct reception, realize the infrared transmission agreement by infrared mobile and electronic lock, control the opening and closing of electronic lock by receiving password that mobile phone sends.When controller receives the information that mobile phone is sent, it is right to carry out cryptographic core, in case success, the unlatching that promptly produces corresponding signal controlling electronic lock.
Improvement of the present invention is to set effective unlocking times of unlocking cipher and unblank the period by the mobile phone infrared interface, and when the number of times that uses valid password to unblank exceeds setting value or exceed when unblanking the period, password lost efficacy.After inferior password lost efficacy, controller will produce next pseudorandom new password according to password last time.
According to the controller that said method is realized, the effective unlocking times of password that its microprocessor program is set is for once, and the period of effectively unblanking is 24 hours, and promptly password is promptly destroyed after using once, inefficacy in password produces one day after.In addition, be no more than 10 seconds the time delay of unblanking that the microprocessor program of controller is set, and be provided with unblank button and the Reset of system button.In case outage, controller is in closed condition.Connecting for convenience, controller provides+12V ,-two kinds of power interfaces of 48V, can utilize the base station back-up source to power.In addition, when taking place that special circumstances are indoor can't power, controller also can carry out powered operation by outdoor interface.
The beneficial effect of the invention: adopt this invention, can realize that not only the management of mobile communication base station and running cost reduce greatly, also can improve safety greatly.

The specific embodiment
As shown in the figure, the flow chart of Fig. 2 is understood one embodiment of the present of invention.
Password of the present invention generally adopts pseudo noise code, can be produced by the software of little processing.
Another kind method is: the sequence pseudo-random code sequence can utilize the shift register network to produce, and this network is made up of R level series connection two-state device shift pulse generator and modular two addition device.By a simple level Four shift register network diagram, it is 15 pseudo noise code that this network can produce code length.
Utilize FPGA can realize that the shift register network is to produce functions such as pseudo noise code signal, and realization logic control and clock distribution.For the TTL signal of FPGA output, its processing method has two kinds: a kind of is directly to deliver to amplifier to carry out signal condition output; Another is with output again behind D/A conversion of TTL process and the signal condition.With the reality test, the author finds because the signal phase shake of FPGA output is comparatively serious, even can cause signal edge shakiness, and exists serious parasitic signal, thereby the pseudo-code of output is second-rate by analysis; And if process D/A nurses one's health output after changing again, this influence can obtain weakening, signal quality can be improved, therefore second method is more desirable, in actual applications, the author just selects this method to carry out circuit design, and selects difference current output type D/A to amplify directly output of back through MAX 4145.
Pseudo noise code based on MAX 4145 produces schematic block circuit diagram as shown in Figure 4.This pseudo noise code produces circuit when working, and system can give FPGA with the pseudo-code data allocations by the parallel port, also can independently produce pseudo-code signal by FP-GA, finishes signal processing, clock distribution, sign indicating number function such as generation and waveform storage synchronously by FPGA simultaneously.The effect of MAX 4145 mainly is to finish the conversion of differential-to-single-ended output and amplification.
MAX 4145 is except having the big characteristics of input impedance, and the error that imbalance of the common-mode gain of its prime and drift produce can be cancelled out each other, and can suppress back level common-mode signal, double-end signal can be become single-ended output simultaneously, to adapt to the needs of ground connection load.Except three amplifiers, MAX 4145 also comprises output short-circuit self-protection circuit and input protection circuit, thereby has increased the survivability of chip.By outer meeting resistance RG can to gain+1V/V～+ be provided with in the 10V/V scope.
Embodiment the present invention mainly utilizes chip microcontroller infrared transmission agreement, can receive the password that various different mobile phones are sent, and finally controls the opening and closing of electronic lock.Single-chip microcomputer adopts TI MSP430 chip, and the infrared transmission agreement adopts the assembler language design to realize.7 pseudo noise code, 15 pseudo noise code, 31 pseudo noise code, 63 pseudo noise code all can, as move register by linear feedback, the certain feedback factor of design produces.
Infrared electronic lock of mobile phone controller characteristic parameter according to the inventive method enforcement:
1, power interface :-48V/+12V; Password figure place: 288bit
2, unblank time delay: be no more than 10 seconds
3, power consumption: when lock cuts out, 12mW; When lock leaves, 7W
4, volume: 200cm
3
Test shows by experiment, the present invention has reached intended purposes, stable performance, practicality is very strong.
