Abstract
The utility model relates to a radar type monitor, comprising a radar detection circuit and a one-chip microcomputer control circuit. Output signals of the radar detection circuit are transmitted to the one-chip microcomputer control circuit through a trigger circuit; output signals of the one-chip microcomputer control circuit are transmitted to an RS 485 communication interface circuit; the one-chip microcomputer control circuit is also in bidirectional data communication with a watchdog circuit. The radar type monitor employs a radar to detect human body signals; when a human body moves in a monitoring scope, the one-chip microcomputer performs identification and determination; the signals are transmitted to a computer terminal host through a system bus to display alarm information and realize antitheft remote monitoring.
Description
Technical field
The utility model relates to a kind of watch-dog, particularly be a kind of radar type watch-dog.
Background technology
Traditional watch-dog, the wired mode of most employing is transmitted warning, needs other wiring just can finish, and does not have remote monitoring function.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of radar type watch-dog with remote monitoring function is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of radar type watch-dog, comprise radar detection circuit and single chip machine controlling circuit, the output signal of described radar detection circuit is transferred to single chip machine controlling circuit through trigger circuit, the output signal of described single chip machine controlling circuit sends to the RS485 communication interface circuit, described single chip machine controlling circuit also with the watchdog circuit bidirectional data communication.
Preferably, described radar detection circuit adopts radar detedtor module I C4 to gather human body signal, and the output terminal of described radar detedtor module I C4 is connected with antenna T.
Preferably, described single chip machine controlling circuit adopts 89S52 single-chip microcomputer IC1.
Preferably, described RS485 communication interface circuit drives chip IC 3 transmission data messages by 75176 interfaces and is sent to the computer terminal main frame.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model adopts the radar detection human body signal, when human body is movable in monitoring range, judge through single-chip microcomputer identification, reach the computer terminal main frame by system bus, display alarm information realizes antitheft remote monitoring.
Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of radar type watch-dog of the present utility model, comprise radar detection circuit 1 and single chip machine controlling circuit 2, the output signal of described radar detection circuit 1 is transferred to single chip machine controlling circuit 2 through trigger circuit 11, the output signal of described single chip machine controlling circuit 2 sends to RS485 communication interface circuit 21, described single chip machine controlling circuit 2 also with watchdog circuit 3 bidirectional data communications.
Described radar detection circuit 1 adopts radar detedtor module I C4 to gather human body signal, the output terminal of described radar detedtor module I C4 is connected with antenna T, when the people is movable in distance antenna T effective range, radar detedtor module I C4 can export a low level signal that continues 10s approximately, this signal is after triode VT1 amplifies, through resistance R 3 current limlitings, be input to the 33rd pin I/O end of 89S52 single-chip microcomputer IC1, after 89S52 single-chip microcomputer IC1 judges, send control signal, drive chip IC 3 by 89S52 single-chip microcomputer IC1 to 75176 interfaces and send the driving command signal, after 75176 interfaces drive chip IC 3 decodings, reach the computer terminal main frame by system bus, show current warning address information by system software, realize antitheft remote monitoring.
Connect to form watchdog circuit 3 by 5045 watchdog module IC2 and 89S52 single-chip microcomputer IC1, prevent that 89S52 single-chip microcomputer IC1 program operation process is in the deadlock state, guarantee the recovery routine operation.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
