1. a lock, is characterized in that,Locking bar, lock bolt, spring, electromagnet, control part A, communication module, energy acceptance portion;

  • Energy acceptance portion is made up of aerial coil and rectification circuit;

    Control part A is one piece of single-chip microcomputer, and single-chip microcomputer comprises;

    microprocessor, program storage device, archival memory, Nonvolatile data reservoir, I/O port (I/O), serial communication port;

    An end (PB1) of control part A connects a termination (1) of magnet spool;

    Communication module is by BDB Bi-directional Data Bus connection control portion A;

    The aerial signal of communication module inputs one end (1) that one end (S1) connects aerial coil, and the aerial signal input other end (S2) of communication module connects the other end (2) of aerial coil;

    Control part A communicates with relative movement device via communication module;

    Output one end (1) of aerial coil connects input one end (1) of rectification circuit, the output other end (2) of aerial coil connects the input other end (2) of rectification circuit, and the alternating voltage that aerial coil exports is via exporting DC voltage (VCC) after rectifier circuit rectifies;

    Aerial coil (630) electromagnetic radiation field energy in relative movement device is to aerial coil, and this energy of electromagnetic field induces alternating voltage and powers to described lock via exporting DC voltage (VCC) after rectifier circuit rectifies in aerial coil;

    The positive voltage output end in energy acceptance portion exports DC voltage (VCC), connects another termination (2) of magnet spool, provides DC voltage (VCC) to electromagnet;

    The direct current pressure side (VCC) of the positive voltage output end connection control portion A in energy acceptance portion, also connects the direct current pressure side (VCC) of communication module;

    The negative voltage output in energy acceptance portion connects ground wire (GND), the GND end of connection control portion A, also connects the GND end of communication module;

    Energy acceptance portion powers to control part A, returns communication module and powers;

    Control part A communicates with relative movement device and comprises;

    both sides carry out predetermined exchanges data, and control part A checks the code data that relative movement device is sent, and control part A accepts the unlock instruction that relative movement device is sent.
