Accompanying drawing
Describe the present invention in detail below in conjunction with two embodiment shown in the drawings:
Fig. 1 represents the calcspar of the regulating circuit that alarm self-adaptation adjusting operational factor is used, and this regulating circuit is adjusted to a fixing resonant frequency of this alarm;
Fig. 2 represents the calcspar of the regulating circuit that alarm self-adaptation adjusting operational factor is used, and wherein the sound of this alarm is transformable.
The explanation of embodiment
Fig. 1 represents the calcspar of the regulating circuit that self-adaptation adjusting alarm operational factor is used.This alarm 1 for example has US 5 414 406 described structures, only shows a field coil 2 in Fig. 1, and by electric current the time, this field coil causes the diaphragm vibration of this alarm.The field coil 2 of alarm 1 is for example powered by automobile storage battery by a power supply 3.In the feed line between power supply 3 and field coil, be provided with a switch 4, this alarm starts by the operation of this switch.
The electric current I of field coil of flowing through is controlled by the electric-controlled switch 5 in the current return that inserts field coil 2.The automatically controlled signal of electric-controlled switch 5 is from a pulse producer 6, and this pulse producer sends one to have certain pulse sequence frequency and have the pulse train of certain percent make.The pulse train that driver 7 that is connected between pulse producer 6 and the electric-controlled switch 5 sends pulse producer reaches a level that is applicable to electric-controlled switch 5.Electric-controlled switch 5 is a semiconductor switch preferably, for example a field effect transistor.So electric-controlled switch 5 switches on and off according to the pulse train that pulse producer 6 produces, thereby the exciting current I of the field coil 2 of flowing through has a shape by the pulse train of pulse producer 6 pulsed frequency given in advance and percent make.
The task of following regulating circuit is, make the alarm that is not subjected to catabiosis or temperature effect or other ectocines carry out work consistently under its resonant frequency, this resonant frequency depends on other parts of total, field coil, magnetic core, diaphragm, shell and the alarm of alarm.An operational factor of alarm 1 is determined as regulating parameter.The operational factor of alarm 1 is its resonant frequency or promptly the flow through exciting current I of field coil 2 and electric-controlled switch 5 of proportional with it parameter preferably.
In the embodiment shown in fig. 1, exciting current I itself is as regulating the parameter input conditioning circuit, but voltage U that derives from exciting current I, exciting current I is transformed into voltage U to be realized with a current-to-voltage converter, in the simplest situation, this current-to-voltage converter is an Ohmage 8.
In the circuit component 9 below current-to-voltage converter 8, voltage U reaches the signal level of the analog-digital converter 10 that is suitable for below.Analog-digital converter 10 just needs when only proceeding digital signal Processing in this regulating circuit.When the signal Processing of simulation, can be without analog-digital converter 10.Digitized adjusting parameter is that voltage U is transfused in the spectrum analyzer 11 of a numeral.Spectrum analyzer 11 is determined one or more eigenwerts of voltage signal U.These eigenwerts for example may be that the relative phase of certain harmonic spectrum component and/or the spectrum of signal U distribute.
One or more eigenwerts of the signal U that is determined by spectrum analyzer 11 are transfused in the signal processor 12.The ratings of these eigenwerts is stored in the signal processor 12, and the operational factor that these ratings are equivalent to a requirement promptly is equivalent to the exciting current I of the requirement of alarm 1.Signal processor 12 is determined the error between one or more ratings that the one or more eigenwerts determined by spectrum analyzer 11 and signal processor 12 store.Signal processor 12 is that signal generator 6 is prepared one or more and this proportional adjusting parameter of error of determining.These one or more adjusting parameters are used for the pulsed frequency and/or the percent make of clamp-pulse generator 6.By this adjustment process, the pulsed frequency of pulse producer 6 and/or percent make are adjusted to like this, be that the actual value determined of signal processor 12 and the error between the ratings become minimum, thereby alarm 1 is to move under the situation of resonant frequency in its optimum frequency.
In order to start alarm, when switch 4 operations, signal processor 12 obtains an enabling signal S.Signal processor 12 be preferably in the ratings of one or more storages and one or more actual values of providing by spectrum analyzer 11 between compare; In other words, adjustment process does not continue, but is undertaken by certain repetition interval.During adjustment process of signal processor 12 each startups, it all sends an enabling signal A to analog-digital converter 10, and this analog-digital converter converts the input signal U of simulation to the digital signal of spectrum analyzer 11 then.Analog-digital converter 10 needn't necessarily only start in the time of signal processor 12 startup adjustment processes, but this analog-digital converter can carry out continuously.
In the embodiment shown in Figure 2, regulating circuit has the identical circuit elements with earlier figures 1 embodiment.So whole squares of Fig. 2 are identical with the reference number among Fig. 1.Compare with Fig. 1, the difference of Fig. 2 embodiment only is that signal processor 12 has an independent signal wire 13.When carrying out explanation embodiment illustrated in fig. 1, mentioned already, in signal processor 12, stored one or more fixedly ratings given in advance.The signal input part 13 of signal processor 12 shown in Figure 2 then can be from outside amount of imports definite value, and these ratings can make the frequency of alarm 1 be different from its resonant frequency to change.So the sound that is produced by this alarm all can change on its frequency and on its volume.The variable ratings that provides on the signal input part 13 of signal processor 12 for example can be from a centralized control unit of automobile.In this case, also can cancel the switch 4 shown in Fig. 1 embodiment, because signal processor 12 is also received the enabling signal of a startup alarm 1 by signal input part 13.In this case, the connection of alarm is from signal processor 12, realizes by the circuit of pulse producer 6 and electric-controlled switch 5 connection field coils 2.
