The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, the utility model is made up of direct supply 1, oscillation step-up circuit 2, circuit for producing high voltage 3, output electrode 4, audible alarm circuit (5), the true Power Generation Road of controllable silicon (6), radio transmitter 7, wireless receiving circuit 8, transmitter box body 11, receiver box body 12; Radio transmitter 7 is loaded in the transmitter box body 11; Other circuit then is contained in the receiver box body 12.

With reference to Fig. 2～6, oscillation step-up circuit 2 is made up of triode BG1, BG2, diode D1, D2, resistance R 4, R6, capacitor C 1, transformer B1 etc.; Circuit for producing high voltage 3 is made up of diode D3～D6, controllable silicon SCR, high-tension transformer B2, B3, capacitor C 3 etc.; Audible alarm circuit 5 is made up of integrated circuit (IC) 1, triode BG5, BD6, resistance R 6, R9, loudspeaker Y, capacitor C 4 etc.; Thyristor gating circuit is made up of resistance R 1～R3, R5, capacitor C 2, field effect transistor BG4 etc.; Radio transmitter 7 is made up of triode BG9, BG10, capacitor C 9, C11, inductance L 1, L2, resistance R 11, R12, button AN etc.; Wireless receiving circuit 8 is made up of triode BG6～BG8, relay J, capacitor C 5～C8, C12, inductance L 3, L4, resistance R 10 etc.

In the practical application, at ordinary times, two groups of duplex contact K1-1, K1-2 of K switch are disconnected, and (K switch can be loaded on the handgrip of suitcase, is convenient to press when people meet; Also can be contained in local fore shaft place such as safety cabinet, desk, door and window, warehouse; Can also be installed in the base position of valuable household electrical appliance), when the robber commits a crime, can connect by trigger switch K, direct supply 1 provides direct current biasing for BG1, BG2, make its starting of oscillation, its output pulse signal is upgraded to 300～500 volts middle pressure behind transformer B1, after diode D3, D4 rectification capacitor C 3 is charged again; To capacitor C 2 chargings, after the voltage on the C2 was charged to certain value, the BG4 conducting produced the control grid that trigger pulse is delivered to controllable silicon SCR to direct supply 1, makes the SCR conducting, thereby strengthened C3 is charged by R5, R1 simultaneously.6～100,000 volts of voltages are exported in the output high power pulse of C3 charging back after boosting as pressure transformer B2, B3, by output electrode 4 outputs, but its output current is lower than 0.08 ampere.Direct supply 1 also can make its conducting for triode BG9 provides flow directing device in addition, and integrated circuit (IC) 1 obtains power supply, and output signal makes loudspeaker Y send chimes of doom.Output electrode 4 has different installation methods for different occasions: as when being used for suitcase (or bag), can be distributed in the output electrode silk on the tank surface; As be door and window, then can be arranged in the output electrode silk on door-plate or the window; As drawing last or the like for desk, safety cabinet etc. then can be loaded on output electrode silk cloth.

This device also can trigger by the fraction of remote control and report to the police or electric shock, and this situation majority is used for suitcase (or bag) and is robbed.Snatched away by the people as suitcase (or bag), the people that then is robbed can press the telepilot of carrying, and press button AN, make BG9, BG10 starting of oscillation, ANT1 sends modulation signal by emitting antenna, the antenna ANT2 of this signal in receiver receives, and amplify through BG7, BG8, drive the BG6 conducting, thereby make the relay J coil electricity, its normally opened contact J1-1, J1-2 adhesive, send chimes of doom and electric shock, (its principle of work as hereinbefore), make the robber in a few minutes, lose capacity of crime, with its uniform.Certainly, this remote control mode is equally applicable to other antitheft occasion.
