Abstract
The utility model relates to an air pressure speech alarm monitoring automotive brake. The power supply input end of the utility model is connected in series with an air pressure probe, and when air pressure is lower than a limit value, a K is closed and the alarm works. The power supply voltage of the utility model is simultaneously input in the power supply end and the triggering end of a speech generator I< C3 > through voltage regulation by a voltage dependent resistor R < V >, a diode D< 1 >, a capacitor C< 1 >, a C< 3 > filtration, a three-terminal voltage stabilizer I< C1 > and a voltage stabilizing tube DW. A speech signal generated by the I< C3 > is coupled by a C< 6 > to a power amplifier I< C2 > for a loudspeaker R< L > to produce sound. The utility model strengthens various anti-interference and impact resistant circuits and has the advantages of reducing false triggering, extending the service life of the alarm and reducing failure rate.
Description
The utility model relates to a kind of annunciator of monitoring automobile brake air pressure.
At present, automobile is because the accident that the braking pressure system failure causes is a lot, the buzzer warnings that adopt in the prior art more, because buzzer warning is all adopted at a plurality of positions on the automobile, in case ring, the driver is difficult for resolution accident position, Chinese patent application CN2167902Y discloses a kind of ＂ automobile with multi-functional language alarm ＂, can carry out language alarm to automobile multi-section position fault, as driving engine voltage, coolant water temperature, braking pressure, lubricating oil pressure and amount of fuel etc., structure is complicated, the cost height, the sensor of each testing circuit of this annunciator adopts normally closed mode, can send language alarm when breaking down, and so long-time energising can influence the work life of annunciator; Because automobile power source is extremely unstable; do not take safety methods such as anti-power supply reversal connection, shock resistance voltage, disturbance rejection; also can influence the annunciator life-span; and this annunciator adopts the multichannel language chip; be subject to disturb and false triggering, the probability height of damage is when a certain road language generation obstacle; the complete machine function is just ineffective, must change a new annunciator again.
The purpose of this utility model is to obtain a kind of air pressure language alarm, no power at ordinary times, and the just energized work of breaking down, and have multiple disturbance rejection, defencive function, fault rate is low.
The purpose of this utility model is achieved in that
A kind of air pressure language alarm, it comprises language generator, power amplifier and loudspeaker, and its key problem in technology is: the power input of annunciator is connected with the air pressure probe K, and power line voltage is gone into language generator I behind protective circuit, mu balanced circuit and filter circuit
C3Power end 1 pin, trigger end 2 pin, the speech signal of generation is from I
C34 pin horsepower input amplifier I
C22 pin, through I

Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is the utility model air pressure language alarm circuit diagram.
Fig. 2 is the scheme of installation of this annunciator.
Referring to Fig. 1,2, the utility model air pressure language alarm assembly JB connects with the air pressure probe K, and K disconnects when air pressure reaches specified value, K closure when air pressure is lower than specified value, and alarm work, at this moment power line voltage is through pizo-resistance R
vAbsorb surge voltage, diode D
1Do the power supply reverse connecting protection, capacitor C

3Filtering is through three terminal regulator I
C1With by resistance R
1, behind the second stage mu balanced circuit formed of stabilivolt DW, input language producer I
C3As operating voltage (1 pin) and energizing signal (2 pin), capacitor C
2Play low-voltage filter and trigger the disturbance rejection double action, I takes place in language
C3The speech signal that produces from 4 pin via R
3, C
4The I that forms
C3Behind the filtered analog signal device, through capacitor C
6Be coupled to I
C22 pin, resistance R
2, capacitor C
5Form speech frequency and adjust circuit, speech signal is via I
C2, C

8The power amplifier of forming is delivered to loudspeaker R
LSounding.
This annunciator can directly substitute the air pressure buzzer phone, needn't change automobile line, and strengthen various interference protection measures, has adopted the kinds of protect circuit: pizo-resistance R
vMatch with three terminal regulator, but impact voltage plays the buffering sorption, three terminal regulator makes the working power quality of whole annunciator very high, with capacitor C
1, C
3In conjunction with making power supply purer; Operating voltage is 10～30VDC, and big or small vehicle can both be general.The trigger end of language generator is in parallel with power end, does not work at ordinary times, does not consume energy, in case there is something special annunciator energized just uses single language sheet can prolong the work life of whole annunciator, reduces fault rate.
