3, voltage stabilizing diode and two diodes ground that is in series in backup voltage-limiting protection branch road.

4, rectangular-shaped radio reception channel module is to be connected with shielding line with external antenna.

5, the external antenna of radio reception is long 20mm, the square antenna of wide 15mm.

6, the modulator tube in multi-code transmitter circuit is low frequencies pipe.

For having a clear understanding of the meaning of the technical program, below special work, explain and explanation:

One, monitoring of the present invention finds that device mainly consists of jointly sampling part and wireless remote control radiating circuit two parts, the former effect is that monitoring ground is dry or has ponding situation, if there is the situation of ponding, send immediately signal, allow wireless remote control launch start launch.The Main Function of the latter's wireless remote control radiating circuit is to send signal to allow, and is placed in the reception programme control circut starting action in receiver within doors, auto dialing, notice a plurality of litiganies within doors.

Two, phone transmitting portions, reception programme control circut, several parts of highly sensitive radio system are jointly to dress up one, be mounted in telephone set, its reason is that these several parts are several parts that are closely related, be convenient to receive by monitoring and find the signal that device sends, produce the function that auto dialing is notified litigant.Its another reason is that the present invention can realize a tractor serves several purposes, can make communication telephones, can realize again relief logical.

Between highly sensitive radio system and external antenna, adopt shielding line to be connected, can greatly improve receiving sensitivity, can largely reduce furniture and the impact of weather on remote control in family.

Three, in the common communication telephones in market, generally all have a number storage function, it is easy to use that telephone set designs the telephone number that is with often puts through of argument of this function, its reason is if be stored in after the storage key in telephone set often dialling plane No. code in advance, putting through while often dialing, a plurality of keys should be dialled and the mode of the code of long number could be transferred to, become and only press the simple and direct form that a key just can be transferred to multidigit number, thereby use very convenient, because there is such characteristic, thereby created important prerequisite for receiver section implementing measure of the present invention, the present invention utilizes this characteristic exactly, in advance in phone, all telephone numbers of litigant have within doors been stored, radio system receives that ground has after the signal of ponding, started reception programme control circut circuit, with it, replace traditional manual dial's mode, this also becomes the important foundation of phone transmission of information for the present invention.

In telephone set, radio reception circuit Main Function is the starting point that control to receive programme control circut, that is to say old man with the signal that sends of transmitter, once receiver receives signal, just can send instruction, allow receive programme control circut and start and start working.The function of order circuit is stored telephone set moves successively except allowing, and can regularly stop simultaneously.Its connotation is, to will no longer opening all storage keys after closing telephone set Hands-free key certain time, will realize the shutdown of telephone set and the automatic stop of whole control system.

Four, why the present invention will make a part of the present invention with telephone set, main cause is can form a complete production network with relevant producer when producing, utilize this part of function of telephone set and structure can save a lot of parts required for the present invention, be convenient to produce also cost-saving, be convenient to produce, be convenient to integrated, to produce larger economic benefit.

Five, adopt 4066 as telephone set lead-in wire and the interface circuit that receives programme control circut, to be connected with following benefit:

(1), volume is little, because just include 4 electronic switches for one 4066, thereby same function can only just can complete compared with the integrated circuit of small size with one, because reception programme control circut is to be contained in telephone set, obvious whole printed circuit board area is less, is conducive to install.

(2), when receiving programme control circut and not working, the electronic switch of 4066 IC interiors is not worked, the extension line of telephone set does not produce any negative interaction to telephone set, telephone set can normal talking.And while receiving programme control circut work, telephone set is produced to correct logic.

Six, the monitoring in the present invention finds that device divides jointly and forms by sampling part, multi-code transmitter and interface circuit between the two.

Its principle is, when ground is while being dry, sampling part is dry, and monitoring finds that part does not have signal, when having ponding, produces state variation, and excitation multi-code transmitter is opened and sent signal.

In measure 1, used multi-code transmitter circuit, main benefit is to be difficult for producing malfunction.Use now the apparatus of remote control many, as locking that car door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the many yards of artificial interferences that just can thoroughly stop afterwards this class.This circuit is realized or its principle of gate-type multi-code transmitter is; When the first end of transmitting programme control circut is exported a high position, it is low that the phase inverter output connecting makes the chip select of this coding integrated circuit of connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner only have corresponding section's chip select work.Due to each coding integrated circuit with or a door mode be input to modulator tube, so form the form of multi-code transmitter.

Seven, after employing measure 4 and measure 5, receiving sensitivity can be greatly improved, furniture and the impact of weather on remote control in family can be largely reduced.

Eight, power supply is an emphasis of the present invention, and the stable of power supply determined the stable of whole properties of product, so special, power supply is made the following instructions to (doing as shown in Figure 7 following explanation):

1, the cardinal principle of voltage stabilizing:

Voltage adjustment triode (903) has adopted to be penetrated with output, there is very strong negative feedback, once after line parameter circuit value is determined, voltage is adjusted triode (903) and just can be stabilized on a concrete numerical value, and this numerical value can meet the requirement of supporting electronic equipment.

2, there is good overcurrent protection and the explanation of Monitoring Performance:

(1), the composition of this part: main overcurrent protection adapted resistance (908) in accompanying drawing 7, overcurrent protection triode (909), light emitting diode (910), jointly composition.

(2), produce overcurrent protection principle: when supporting equipment is short-circuited after fault, (after electronic equipment part is bad, the normal fault occurring is that complete machine electric current increases), electric current through overcurrent protection adapted resistance (908) increases, after voltage between the emitter over overcurrent protection triode (909) and base stage, overcurrent protection triode (909) is open-minded, at this moment voltage is adjusted the base bleeder current of triode (903), thereby sealing voltage is adjusted the output of triode (903), the shunting route of base flow is from the emitter of overcurrent protection triode (909) to collector, and after light emitting diode (910) to ground wire.

(3), produce the principle of indication after the fault that is short-circuited: the one, overcurrent protection triode (909) is open-minded, electric current has passed through light emitting diode (910), forms light indication.The 2nd, triggered the indication of alert sound sheet (911) formation sound.At this moment light emitting diode (910) also has a vital role, to alert sound sheet (911) pressure limiting, is unlikely to damage.

(4), there is automatic protection and automatic restorability: when overcurrent protection adapted resistance (908) voltage increases, overcurrent protection triode (909) is automatically open-minded, after Failure elimination, automatically recovers.

3, there is the explanation of good overvoltage capabilities:

Lightning protection and overvoltage are also emphasis of this bright research, because functional effect is good for this reason, can work at thundery sky, and needn't power-off.

The first, be furnished with backup voltage-limiting protection branch road, this branch road is in accompanying drawing 7 905, during Main Function, when having thunderbolt to gush pressure, output terminal is carried out to voltage-limiting protection.The protection philosophy becoming is; the steady value of this pipe is higher than the adjustable voltage stabilizing branch road being comprised of voltage accurate adjustment resistance (906) and voltage coarse adjustment voltage stabilizing diode (907); so when rectification is exported in by the state of adjustable voltage stabilizing branch road clamper; it is open circuit; if rectification output end has thunderbolt to gush pressure; adjustable voltage stabilizing branch road both end voltage is too high, and backup voltage-limiting protection branch road (905) is opened again voltage is adjusted to triode (903) base stage pressure limiting, protection output terminal.The benefit of design is like this, is furnished with backup voltage-limiting protection branch road when overvoltage not, in open-circuit condition, does not produce " electrical wear ", does not damage, and is a kind of " backup " state, thereby when rectification overvoltage, can plays one's part to the full, and produces unexpected possibility minimizing.

The second, voltage adjustment triode is high inverse-voltage tube, and lightning protection effect is good.

Its reason is, this pipe breakdown reverse voltage is conventionally at hundreds of volts, and 78 serial back-pressures are generally 30 volts.Than 78 conventional series, to exceed more than 10 times, so overvoltage is had remarkable power of endurance.

Three, be equipped with anti-thunder tube, this pipe breakdown protection voltage is tens of volts, after coordinating, has very large surplus with the voltage adjustment triode of high back-pressure.

4, in the higher place of civil power and period, can not damage the reason of circuit: because of voltage, adjusting triode is high inverse-voltage tube, although the voltage of now bridge-type output is high, also can be far below high inverse-voltage tube withstand voltage.

5, can be in the main cause of the lower place of civil power and period work: the one, the voltage in circuit is adjusted triode, can not produce additional electrical pressure drop, as long as bridge-type voltage is higher than output voltage, this pipe just can work, with regard to energy voltage stabilizing.(illustrate: if the input voltage expansion scheme that adopts traditional triode to connect with three end integrated circuit, three end integrated circuit normal operation required voltages must be provided, also need triode operating voltage, main product has been given birth to triode supplementary loss voltage so simultaneously.And when civil power is low, this is valuable voltage.) it two is that because of voltage, to adjust triode be high inverse-voltage tube, so can bridge-type output voltage can be designed higherly when design, when civil power is low, at this moment bridge-type voltage be can not output very low, just can do certain compensation.

6, can expand the explanation of civil power variation range: because civil power does not damage circuit when high, and still can work when lower.So can expand the working range that civil power changes.

7, can adjust the reason of different output voltage stabilizing values.In adjustable voltage stabilizing branch road, the pressure drop of voltage coarse adjustment voltage stabilizing diode is leading role, and the shared ratio of the voltage accurate adjustment resistance of connecting is very little, so also can do the use of accurate adjustment, the benefit of accurate adjustment is can the furnishing normal voltage required to accumulator floating charge, as 6.6 volts; 12.8 volts, etc.

After the invention process, there is following outstanding advantage:

1, supporting power supply has following advantage: (1), source of stable pressure can provide stable voltage, there is again monitoring effect, if the equipment being equipped with has moderate fault, warning immediately, due to this announcement is that initiatively its meaning is to have " fault " just to accuse it, non-fault is not indicated, so more supporting special electronic equipments are as very large in protector meaning, because can avoid security personnel's " blank ".

(2), indicating fault meaning performance, the light indication of existing light emitting diode, has again the moderate sound indication of sound.

(3), over-flow protecting effect is good, protection is large, and adjust the heating degree of pipe can be very not large.

(4), anti-thunder and overvoltage protection are effective.Can be because thundery sky quits work, if be that security personnel's series products is supporting with this power supply, not guarantee that " security personnel " do not produce blank, and by three traditional end integrated circuit or traditional triode and the co-design of three end integrated circuit, be difficult to realization.

(5), adapt to widely, than traditional stabilized voltage supply, have wider adaptive faculty, high at the voltage that meets accident, can not damage.And also can work in the lower place of voltage and period.

(6), there is the voltage stabilizing value of decimal in available adjustment output generation, be convenient to the floating charge of accumulator science.There is overcurrent protection simultaneously.Be fruitful or other electronic products have excellent performance after supporting.

(7), circuit letter essence, the benefit one of generation is easily to produce and debugging, the 2nd, out of order is few, so the reliability of the circuit improving.

2, when having excess surface water, the present invention will notify personnel outside automatically, to take measures as early as possible, this is for saving water source, and the consequence that reduces ponding generation is all very useful to oneself, to other people.

3, advanced in performance, owing to utilizing network platform transmission of information, hurry up, and with people place range-independence, single also have following characteristics with regard to this function: one of be, can call out multi-section phone simultaneously, allow a plurality of people know, the telephone alarm of having avoided a lot of other class character to report to the police can only be notified a people deficiency; Two be that each phone is repeatedly called out, can discharge many objective unfavorable factors, as the line is busy, the factor such as network signal is bad, so notify from a phone call great efforts.Three, after closing of the circuit, not only have voice message, and can listen to that water valve does not close and at the acoustic scene of flowing water, true feeling is strong.

4, anti-accident is good because monitoring part with transtelephonic partly for wireless remote control contacts, can find devices with a plurality of monitorings, the benefit of generation is to avoid an accident of monitoring discovery part malfunctioning, the 2nd, can realize the monitoring of a plurality of points.

5, after the invention process, telephone set still has all communication functions of phone, and a tractor serves several purposes does not increase ornaments and the apparatus of family, does not affect life and the custom of family, and family does not have too much ornaments and affects attractive in appearance.

6, monitoring part is effective, and element is few, and volume is little, and fault is few.

7, highly sensitive radio remote control receiver has been used external antenna, makes signal transmission more accurate.

8, the various electrical equipment of having stopped social upper existence disturb, and it is more accurate to launch.
