Description
Technical field
The present invention relates to optical communication field, relate to particularly the coding/decoding method of a kind of optical trigger and light signal receiving control apparatus, light signal receiving control apparatus.
Background technology
The wireless light communication technology claims again the visible light communication, and its high-frequency by led light source glimmers to communicate, and has light to represent 1, unglazed representative 0, and its transfer rate is up to the per second gigabit.The wireless light communication technology is because its data are difficult for disturbed and catch, and optical communication equipment is made simple and should not be damaged or demagnetization, can be used for making the wireless optical encryption key pair.Compare with microwave technology, wireless light communication has quite abundant frequency spectrum resource, and this is that general microwave communication and radio communication are incomparable; Visible light communication can be suitable for any communication protocol, be applicable to any environment simultaneously; Aspect security, it compares traditional magnetic material, need not to worry the demagnetization problem, needn't worry that more Content of Communication stolen by the people; The equipment of wireless light communication sets up convenient flexibly, and with low cost, is fit to extensive popularization and application.
Gate control system is exactly the system that exit and entrance is carried out control, and it is to develop on traditional door lock basis.Traditional mechanical door lock only is simple mechanical hook-up, and no matter how reasonable structural design is, and how firm material is, and people can open it by various means.Pretty troublesome at a lot of passage of discrepancy personnel (office block, hotel guest room) key management, key loss or personnel change and will change lock ﹠ key together.For addressing these problems, the electronic magnetic card lock has just appearred, electronic password lock, the problem of electronic magnetic card lock is that information is replicated easily, and it is large to wear and tear between card and the card-reading machine, and failure rate is high, and safety coefficient is low; The problem of electronic password lock is that password is revealed easily, has no way of again having looked into, and safety coefficient is very low.Simultaneously, the product in this period is installed in outdoors owing to mostly adopting Card Reader part (Password Input) and control section to be combined, and is easy to by the people at the outdoor lock of opening.In recent years along with the development of contactless card technology, biological identification technology, the system that the various technology such as induction cassette gate control system, fingerprint entrance guard system occurred, but induction cassette gate control system complex operation, fingerprint entrance guard system has fingerprint and easily is stolen, the shortcomings such as client is easily damaged, and discrimination is low.
For addressing the above problem, the photon gate control system is arisen at the historic moment, the photon gate control system generally includes optical signal launcher and light signal receiving control apparatus, optical signal launcher is used for the light signal that emission contains unlocking cipher information, the light signal receiving control apparatus is resolved light signal after receiving light signal, if light signal contains unlocking cipher, then controls door lock and opens, otherwise, then close.The light signal receiving control apparatus uses dry cell power supply, power consumption is larger, need often to change battery, use is brought inconvenience, the excessive use dry cell is also to environment, therefore, how the light signal receiving control apparatus is carried out Design of power saving, become the problem that the photon gate control system is needed solution badly.
Initial optical signal launcher coding adopts is that number with high level represents signal, and each high level lasting time is about about 2ms, every group of maximum four high level, and every group of level number represents the 2bit signal.For example, when the high level number is 1 in one group of signal, represent 00; When the high level number was 2, representation signal 01 was when the high level number is 3 interval scale signals 10; When the high level number is 4, representation signal 11.Distinguish with low level delay between every group of signal, be about 30ms low level time delay.
High level and low level all have certain time delay, and therefore, the light signal receiving control apparatus can be decoded to the received signal by the high level on the I/O pin that detects its control module and low level when receiving signal time delay.With the beginning of electrical level rising edge as a high level, when detecting rising edge, the beginning timing, when high level lasting time during greater than 1.5us, think effective signal, record high level number, with negative edge as a low level beginning, when detecting negative edge, the I/O pin begins timing, when low duration is thought the end of one group of signal during greater than 20ms, think then that signal receives or the signal receive interruption when I/O pin low duration during greater than 75ms, restart detection signal.
The high level number that the coding/decoding method corresponding with above-mentioned existing coding method need be exported and detect is more, causes signal very unstable, and the whole transmitting time of signal and time of reception are longer, and data rate is slow.
