Abstract

A composite apparatus contains a pair of small size transmitting /receiving wireless remoter, added with small relay, reed pipe, four-sound piece and buzzer, wherein the slave unit emitting radio wave, the master unit receiving signal and amplifying then outputting power supply to make relay switching on, the normal on state converted to off state, when the distance between master and slave unit is greater than the standard distance, the reed pipe four-sound piece switched on and making the buzzer sounding a 60-80 db warning.

Description

Mother and sons' machine

This gadget is the utilization of the anti-lost aspect of a kind of radio transmission in the electronic applications and reception.Nest divides machine tool Fig. 1 and handset Fig. 2 two, and handset pipe emission machine tool pipe is accepted, and when static utensil needed out using, (it can play the protection child or the protection suitcase is copied the gram case; If you think the important item that needs protection) as beeper, and handset is copied gram case or child with being attached to the machine tool wearing between waist, and on perhaps you thought the article that need protection, distance was selected by you, and 0.5-1 rice or 1-5 rice shelves, you think the safe distance of selecting this when surpassing, and machine tool just proposes alert cry, and concrete operations are as follows:

Be equipped with each one group of two groups of power supply 3V-6V and big button cell 3V in the machine tool; be equipped with 6-9V lamination battery one joint in the handset; static handset camel after on the machine tool; machine tool and handset are pulled out simultaneously to the left and right; be machine tool left handset just can open operating switch to the right, be presented at work light on the machine tool and light Fig. 3 (redness) handset and put your claimed place into; what if your selection needed protection is bag, selects 0 so.5-1 rice shelves are children if you need protection; Select 1-5 rice shelves so.If you forget bag in car, and in the time of so just will stepping out car door, it will remind you.

The making of mother and sons' machine is to install some miniature relay Fig. 4 tongue tube Fig. 5 four tones of standard Chinese pronunciation sheet Fig. 6 and buzzer Fig. 7 again additional with a pair of small-sized emission Fig. 8 and the radio remote controller that receives Fig. 9, and so on electric device constitute.

Solenoid on relay Fig. 4 is powered by machine tool output department, and two set of connections stakes on the relay are the conducting shape for one group, one group is to disconnect shape (when not switching on) in the time of machine tool work, output department powers to relay, solenoid makes two set of connections stakes exchange, it is the disconnection that is of conducting, and disconnect be conducting, four tones of standard Chinese pronunciation sheet and buzzer are installed and can be treated that electricity inserts by sounding, when not switching at ordinary times, the conducting wiring pile also inserts 3V button electricity, and 3V button electricity is subjected to tongue tube control and four tones of standard Chinese pronunciation sheet is failed sounding.

Little red light indicating operating status.

The making of mother and sons' machine is for reference with a pair of small-sized radio car repacking figure that transmits and receives.Radiating circuit is the high frequency pusb pull oscilator that constitutes with two 3DG201 or 3DG100 (both 3DG6), about the about 40MHZ of frequency of oscillation.Press AN switch connection power supply and promptly produce vibration, send constant amplitude high-frequency signal electric wave by transmitting antenna, fine setting LC tank capacitance device can change tranmitting frequency.

Receiving circuit includes reception antenna, resonant tank, rectification amplifying circuit and monostable triggering timer etc.The high-frequency electric wave that transmitter sends enters resonant tank through reception antenna, is coupled to L4 by L3, becomes direct current through the 2AP9 rectification and injects the 3DG6 ground level.555 connect into monostable timing circuit, and timing value length is decided by the product of R4C8, approximates 1.1R4C8, and R4 can select for use between 1K Ω-5.1M Ω, and C8 can select for use with interior at 1000UF.With regard to conducting, so the 555 set output high level that are triggered, LED is by bright deepening when 3DG6 has base current, and relay J 1 is inhaled the moving control load (the load part does not provide, and can make by oneself) that goes.3DG6 by conducting become by the time rise and regularly begin, regularly finish after second through 1.1RC, 555 revert to low level output reset mode, LED lights again, J1 discharges.

Requirement to 3DG201 is HFE 〉=80, and FR 〉=200MHZ also can be with 3DG100 or 3DG101 (being 3DG6).Loop inductance coil L2 with the enamelled wire about φ 1MM on φ 10MM plastic tube around 9 circles, centre cap elongates about 25MM again, (pitch of turn should evenly), use then enamelled wire about φ 0.7MM outside L2 around 5 circles as L1, and fix, with sealing with wax.Antenna can be made with bicycle spoke.

3DG6 can be with any small-power NPN silicon transistor, as long as the HFE of little electric current (1MA) is just passable greater than 80 among the figure.Relay J 1 can be used 6V small power electromagnetic type, as JQX-4F, also can control toy motor M.Enamelled wire about reception antenna loop inductance coil L3 usefulness φ 1MM elongates 25MM around 9 circles at φ 10MM on the long 50MM shortwave bar magnet, and close on bar magnet with the enamelled wire about φ 0.5MM again is L4 around the 5-6 circle, and last sealing wax is fixed.Reception antenna can be used the flexible conductor about 1M.

After circuit installs, connect circuit, make transmitting antenna and reception antenna at a distance of about 1M, regulate emission tank capacitor and reception antenna tank capacitance device, make the two resonance frequency unanimity, all can make 555 the 2nd pin voltages will be in operate condition at following LED of 1V and J1 (musical film) so press AN at every turn.Check that the straightforward procedure whether radiating circuit vibrates is, ammeter of AN switch ends string, the electric current increase then illustrates and vibrates when grabbing antenna with hand.555 outputs can not become the reason of high level, are connected with the fault except element has problem or circuit, and the resonance frequency that is exactly launching circuit and reception antenna loop is inconsistent, should careful tuning the two unanimity that makes work until timing.

Claims

Mother and sons' machine is subordinate to the anti-lost gadget that electronic applications is a kind of radio transmission and reception.Radio transmission and reception have been very usual technology, and I install a small-sized relay additional at the output of machine tool receiver, the function in the time of prolonging emission and accept electric wave and break, play all valuable objects of easily losing of protection can for.

What here need protection is that the terminal efferent of (1) receiver installs miniature relay additional, bears mutually with combination (2) the machine tool handset of microphone device and to draw back be the tongue tube function of turning circuit on the plane.
