Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The invention provides a single-pole passive lock, which has the working principle that bidirectional communication is realized between a key and a lock, so that the aims of knowing the state change in the lock in real time and ensuring the use quality of an intelligent lock are fulfilled.
The present invention will be described in further detail with reference to examples and specific embodiments.
A single-pole passive lock comprises a key and a lock which are matched with each other;
the key and the lockset realize signal connection in a bidirectional communication mode; the key can acquire the state of the lock or the instruction execution result. The method comprises the following specific steps:
the lockset comprises a lockset shell, a lockset MCU arranged in the lockset shell, a one-way conduction diode D1 arranged in the lockset shell, an energy storage capacitor C1 arranged in the lockset shell, a first switch SK1 arranged in the lockset shell and a protection resistor RL arranged in the lockset shell;
the cut-off end of the one-way conduction diode D1 is communicated with an SVCC pin of the lock MCU;
one end of the energy storage capacitor C1 is communicated with an SVCC pin of the lock MCU, and the other end of the energy storage capacitor C1 is grounded;
one end of the first switch SK1 is communicated with the SRX pin of the lock MCU, the other end of the first switch SK1 is communicated with the STX pin of the lock MCU, and the end of the first switch communicated with the SRX pin is also connected with the conduction end of the one-way conduction diode;
one end of the protection resistor RL is connected with the end part of the first switch communicated with the STX pin, and the other end of the protection resistor RL is grounded.
The key comprises a key shell, a key MCU arranged in the key shell, a second switch KK1 arranged in the key shell, a comparator arranged in the key shell and a collecting resistor Rs arranged in the key shell;
one end of the first switch KK1 is communicated with a KVCC pin of the key MCU, the other end of the first switch KK1 is communicated with a KTX pin of the key MCU, and the first switch is controlled to be communicated or disconnected by a KSW pin of the key MCU;
the comparator is communicated with a KRX pin of the key MCU;
one end of the collecting resistor Rs is communicated with the comparator, and the other end of the collecting resistor Rs is grounded;
after the key is inserted into the lockset, one end of the first switch, which is connected with the KTX pin, is connected with the conduction end of the one-way conduction diode; and one end of the acquisition resistor connected with the comparator is connected with one end of the protection resistor, which is grounded.
The specific use steps of the invention are as follows: as shown in fig. 1 again, after the key inserted the tool to lock, key MCU can charge for electric capacity C1 through KSW pin control switch KK1, KK1 when switching on, and the SRX of data to lock is sent to the KTX through the key when KK1 breaks off, because the effect of electric capacity, can continuously supply power, and tool to lock MCU can receive the data that the key sent like this.
After the key successfully sends data to the tool to lock, the key opens KK1 through the KSW pin and continues to supply power to the lock, the tool to lock can send data through the STX pin, switch SK1 switches on when STX is high, the electric current forms the return circuit through RL and Rs, RL ═ 60 ohm, Rs ═ 1 ohm, electric current I ═ KVCC/(RL + Rs) + I 'in the return circuit, I' is the electric current that lock MCU work consumed, when STX is low switch SK1 breaks, return circuit electric current I ═ I 'because I' is less can be ignored, Rs is signal acquisition resistance, the electric current of return circuit converts the small voltage signal into, after the comparator plastic amplification, become the distinguishable signal of KRX pin. From the above analysis, it can be seen that when STX is high, the voltage collected by Rs is also high, and when STX is low, the voltage collected by Rs is also low, and after Rs passes through the comparator, the amplitude is only increased, and the phase is not changed, so the STX and KRX signals are consistent.
Through the mode, the single-pole passive lock provided by the invention achieves the purposes of knowing the state change in the lock in real time and guaranteeing the use quality of an intelligent lock by realizing two-way communication between the key and the lock.
