Background technology
A few days ago, particularly in park and market, the event of losing child and old man occurs repeatedly, old man's loss and the killed event of baby become the focus of network and media report words, on market because existing tracking equipment lacks, or preparation install inconvenient, complicated operation, expensive, can't obtain due promotion and application.
Summary of the invention
The object of the present invention is to provide a kind of symmetrical expression wireless short-distance warning device, this warning device has low-power consumption, low radiation, and environmental protection, easy for installation, simple to operate, price is low, safe and reliable.
For achieving the above object, a kind of symmetrical expression wireless short-distance of the present invention warning device, it is characterized in that: this warning device comprises wireless signal transmitting device and wireless signal receiver, the structure of wireless signal transmitting device and wireless signal receiver is identical, all single-chip microcomputer STC89C52RC, wireless module nRF24L01 and acoustic-optic alarm, consists of; Single-chip microcomputer STC89C52RC is connected with acoustic-optic alarm with wireless module nRF24L01 respectively, and single-chip microcomputer STC89C52RC is controlled signal reception and the emission of wireless module nRF24L01 by the signal controlling end; Described acoustic-optic alarm is comprised of triode Q, hummer L, current-limiting resistance R and light emitting diode D, the base stage of triode Q is connected with the audio signal output end of single-chip microcomputer STC89C52RC, the grounded emitter of triode Q, the collector of triode Q is connected with power supply by hummer L, the signal output part of single-chip microcomputer STC89C52RC is connected with current-limiting resistance R, light emitting diode D afterwards and power supply joins, keyswitch K mono-end is connected with single-chip microcomputer STC89C52RC external interrupt pin, other end ground connection.
In technique scheme, a kind of symmetrical expression wireless short-distance of the present invention warning device is that a kind of wireless short-distance based on STC898C52 single-chip microcomputer and wireless communication module nRF24L01 is reported to the police, this system by handset to the continual transmitted signal of machine tool, when handset is left the scope that machine tool can accept, machine tool can carry out sound and light alarm automatically.When handset is in machine tool is accepted scope, the light emitting diode of machine tool can be normally luminous, shows and received the signal that handset is sent.When handset is left, while having exceeded the scope that machine tool can receive, machine tool is reported to the police immediately, and light emitting diode can glimmer and do not stop, and shows that the signal machine tool that handset sends can't receive.The present invention has the following advantages: the first, this device power consumption is low, radiation is low, environmental protection, to human body without injury.The second, easy for installation, simple to operate; The 3rd, price is low, safe and reliable, is conducive to apply.
The accompanying drawing explanation
Fig. 1 is the theory diagram of a kind of symmetrical expression wireless short-distance of the present invention warning device;
Fig. 2 is the circuit theory diagrams of acoustic-optic alarm in a kind of symmetrical expression wireless short-distance of the present invention warning device.
Embodiment
Below in conjunction with accompanying drawing, a kind of symmetrical expression wireless short-distance warning device of the present invention is described in further detail.
From Fig. 1, Fig. 2, a kind of symmetrical expression wireless short-distance warning device of the present embodiment comprises wireless signal transmitting device and wireless signal receiver, the structure of wireless signal transmitting device and wireless signal receiver is identical, all single-chip microcomputer STC89C52RC, wireless module nRF24L01 and acoustic-optic alarm, consists of; Single-chip microcomputer STC89C52RC is connected with acoustic-optic alarm with wireless module nRF24L01 respectively, and single-chip microcomputer STC89C52RC is controlled signal reception and the emission of wireless module nRF24L01 by the signal controlling end; Described acoustic-optic alarm is comprised of triode Q, hummer L, current-limiting resistance R and light emitting diode D, the base stage of triode Q is connected with the audio signal output end of single-chip microcomputer STC89C52RC, the grounded emitter of triode Q, the collector of triode Q is connected with power supply by hummer L, the signal output part of single-chip microcomputer STC89C52RC is connected with current-limiting resistance R, light emitting diode D afterwards and power supply joins, keyswitch K mono-end is connected with single-chip microcomputer STC89C52RC external interrupt pin, other end ground connection.The present embodiment is that a kind of wireless short-distance based on STC898C52 single-chip microcomputer and wireless communication module nRF24L01 is reported to the police, this warning device by handset to the continual transmitted signal of machine tool, when handset is left the scope that machine tool can accept, handset and machine tool can carry out sound and light alarm simultaneously automatically.When handset is in machine tool is accepted scope, machine tool light emitting diode D can be normally luminous, shows and received the signal that handset is sent.When handset is left, while having exceeded the scope that machine tool can receive, machine tool is reported to the police immediately, and hummer L can sound a buzzer, and light emitting diode D can glimmer and do not stop, and shows that the signal machine tool that handset sends can't receive.Keyswitch K presses, the handset sound and light alarm, and purpose is to judge position by sound and light alarm.
The present embodiment is when practical operation, and wireless signal transmitting device and wireless signal receiver all can transmit and receive signal.When the power supply of wireless signal transmitting device and wireless signal receiver is opened simultaneously, after the power light of wireless signal transmitting device and wireless signal receiver is bright, the signal transmitting and receiving pilot lamp postpones to light, and illustrates and normally connects, and starts working.
When wireless signal transmitting device quits work, now, the hummer L of wireless signal receiver calls out, simultaneously with the light emitting diode flash for prompting; Report to the police successfully! After pressing the independent button of wireless signal receiver, wireless signal receiver stops piping, if wireless signal transmitting device continues to quit work, wireless signal receiver continues to report to the police; When the power switch of opening wireless signal transmitting device, wireless signal transmitting device and wireless signal receiver signal transmitting and receiving pilot lamp are lighted simultaneously, the wireless signal receiver stop alarm.
When wireless signal receiver quits work, now, wireless signal transmitting device is reported to the police, and wireless signal transmitting device, after the distance wireless signal receiver far can't receive signal, can report to the police to frighten the bad person on one's own account.When the power switch of opening wireless signal receiver, the wireless signal transmitting device stop alarm.
