Description of drawings
Hereinafter will be according to describing embodiment of the present utility model shown in the Figure of description in detail, described accompanying drawing is as follows:
Fig. 1 illustrates the structural drawing according to the acoustic-optic alarm 100 of embodiment of the present utility model.
Embodiment
Hereinafter, identical Reference numeral refers to components identical.
Fig. 1 illustrates the structural drawing according to the acoustic-optic alarm 100 of embodiment of the present utility model.Shown in Fig. 1 the right, AC power 104 is connected in parallel to each other with other four routes and constitutes first circuit loop, wherein, these four routes in parallel are respectively, the normal opened contact AUR1 of auxiliary relay AUR connects with power module 105 and constitutes first route in parallel, timing relay TIM constitutes second route in parallel separately, auxiliary relay AUR connects with the normally closed contact CAN1 of pump contactor CAN and constitutes the 3rd route in parallel, and pump contactor CAN connects with the normal opened contact TIM1 of timing relay TIM and constitutes the 4th route in parallel.
In addition, power module 105, voice module 106, audible-visual annunciator 107 formation second circuit parallel with one another loops.It should be noted that in the utility model, can bypass voice module 106, and directly that power module 105 is in parallel with audible-visual annunciator 107.
Preferably, can be with resistor of power module 105 series connection in the second circuit loop, the electric current that flows through power module 105 with restriction is unlikely to excessive and burns device.More preferably, this resistor can be a variohm.
In operation, when AC power 104 powered on, output AC voltage for example was the alternating current of 110V.
Correspondingly, this alternating voltage is applied on four routes in parallel in parallel with it in first circuit loop.At this moment, because the normal opened contact TIM1 of timing relay TIM and the normal opened contact AUR1 of auxiliary relay AUR all temporarily are in normally open, therefore the pump contactor CAN that connect with normal opened contact TIM1 and the power module 105 of connecting with normal opened contact AUR1 all are in off state and temporarily also must not.
Yet, timing relay TIM under alternating voltage electric, and because the normally closed contact CAN1 of pump contactor CAN temporarily is in normally off, therefore the auxiliary relay AUR that connects with normally closed contact CAN1 is also.
Then, because that auxiliary relay AUR gets is electric, impel the normal opened contact AUR1 closure of auxiliary relay AUR, so the power module 105 of connecting with normal opened contact AUR1 powers on.Thereupon, the alternating voltage that power module 105 is exported AC power 104 is converted to DC voltage, for example the alternating voltage of 110V is converted to the DC voltage of 12V.This DC voltage is applied in the second circuit loop on the voice module 106 and audible-visual annunciator 107 in parallel with power module 105, thereby start voice module 106 and audible-visual annunciator 107, make voice module 106 send voice messaging, and audible-visual annunciator 107 sends sound and light, and then reminds the personnel around the shuttle car to notice that shuttle car starts.
Meanwhile, timing relay TIM is also getting.After passing through the specific period (for example 6 seconds), timing relay TIM must impel its normal opened contact TIM1 closure under the electricity condition, and like this, the pump contactor CAN that connects with normal opened contact TIM1 gets.Subsequently,, impel the normally closed contact CAN1 of pump contactor CAN to open, thereby the auxiliary relay AUR that connect with normally closed contact CAN1 is cut off the power supply because pump contactor CAN gets electricly.Because auxiliary relay AUR outage, impel the normal opened contact AUR1 of auxiliary relay AUR to reopen, like this, to be connected with AC power 104 disconnections with the power module 105 of normal opened contact AUR1 series connection, thereby make power module 105 no longer to voice module 106 and audible-visual annunciator 107 power supplies, therefore, voice module 106 and audible-visual annunciator 107 will no longer send corresponding signal.
To sum up, employing is according to acoustic-optic alarm of the present utility model, can be under the situation that AC power 104 powers on, keep voice module 106 and/or audible-visual annunciator 107 to send self signal Da Teding period, and after the described specific period, thereby voice module 106 and/or audible-visual annunciator 107 will cut off the power supply and no longer send corresponding signal.
Can regulate the length that timing relay TIM changes the described specific period according to concrete needs.For example, the described specific period can be set at 6 seconds.
