Description

Technical Field

[0001] This utility model relates to the field of sound and light alarms, and in particular to a sound and light alarm and voice prompt device. Background Technology

[0002] With the widespread application of intelligent systems, equipment fault monitoring and alarm technology has become a crucial link in ensuring stable system operation. Traditional alarm devices mostly use single light or sound signals for prompting, which suffers from problems such as ambiguous alarm information, difficulty in identifying fault types, and unfriendly interaction between alarm information and management personnel. Especially in complex systems with multiple scenarios such as communication failures, abnormal system pressure, and flooded environments, staff often have to spend a lot of time troubleshooting the source of the fault, delaying emergency repairs. Although there are audible and visual alarm devices in existing technologies, they generally lack the function of differentiated voice broadcasting of fault types. In addition, conventional devices lack fault early warning mechanisms and cannot provide early warnings when the system is in a critical state, resulting in insufficient emergency response time in the event of a sudden failure. For water-related faults (such as water accumulation in puddles, flooded ground, etc.), existing devices mostly use a single threshold triggering mechanism, lacking multi-level early warning and intelligent fault type discrimination capabilities, making it difficult to meet the accurate alarm requirements under complex operating conditions.

[0003] Therefore, there is an urgent need to develop an audible and visual alarm and voice prompt device that integrates sound and light alarms, provides differentiated voice broadcasts, and offers tiered early warnings. Utility Model Content

[0004] To address the current inability to provide differentiated voice broadcasts, this invention provides an audible and visual alarm and voice prompt device that can provide integrated audible and visual alarms for faults and can provide corresponding voice alarms based on different fault types.

[0025] This utility model embodiment provides an audible and visual alarm and voice prompt device, see reference. Figure 4The device includes a chassis 1, inside which is a sound and light alarm module. The electrical connection components of the sound and light alarm module include a signal filtering component, a signal processing component, a light alarm component, and a voice alarm component, all connected in parallel and forming a circuit with the power supply. The electrical connection components refer to the collection of all electrical circuits in an electrical product. For example, the signal filtering component is used to filter interference signals, which are typically short signals while alarm signals are long signals. The signal filtering component usually needs to be connected to an external signal output source. The signal processing component processes the alarm signal. The light alarm component emits a light alarm upon receiving an alarm signal, typically a flashing light. The voice alarm component emits a voice alarm upon receiving an alarm signal and can emit different voices depending on the alarm signal. For example, the total input voltage of the sound and light alarm module is AC220V 50Hz. Figures 1-3 In Chinese, wires starting with L represent live wires, and wires starting with N represent neutral wires.

[0026] Before describing the components, let's first explain the basic working principle of a relay: A relay generally consists of a coil and contacts, such as normally open and normally closed contacts. A normally closed contact is one that is closed when the relay coil is not conducting; that is, the normally closed contact is conducting when the coil is not conducting. A normally open contact is one that is open when the relay coil is not conducting; that is, the normally open contact is not conducting when the coil is not conducting. When the relay coil conducts, the contacts will change accordingly, for example, the normally open contact will close, and the normally closed contact will open. Similarly, the principle of a time-delay relay is the same. When the coil of a time-delay relay conducts, its contacts will respond after a set delay time. If the coil of the time-delay relay no longer conducts within the delay time, then the contacts will not open. This delay response mechanism can effectively filter out short signals.

[0027] Signal filtering components: See Figures 1-3 This includes a first intermediate relay KA1, a energized delay relay KT1, and an indicator light HL1 connected in parallel. The input bus of the signal filtering component also has a total alarm signal input ZBJ connected in series. For illustrative purposes, as... Figure 1As shown, the main alarm signal input ZBJ is normally open (i.e., disconnected). When a fault occurs, the external signal output source will close the main alarm signal input ZBJ (i.e., conduct), thus energizing the coils of the first intermediate relay KA1 and the energized time-delay relay KT1. If the duration of the alarm signal exceeds the delay time of the energized time-delay relay KT1, the normally open contact of the energized time-delay relay KT1 will close. Typically, the alarm signal fed back from the external signal output source will remain valid until the fault is addressed, keeping the contacts of the energized time-delay relay KT1 open. Conversely, interference signals usually have a shorter duration. Therefore, the energized time-delay relay KT1 in this invention can filter interference signals fed back from the external signal output source. As for the indicator light HL1, it illuminates when an alarm signal is input and turns off when the alarm signal disappears. However, the indicator light HL1 does not serve as a final determination of whether a fault exists; it is merely an indicator light used to provide tiered warnings and alert personnel to potential faults.

[0028] Signal processing components: See Figures 1-3 The system includes a control relay FB, with the normally open contact of the first intermediate relay KA1 and the normally open contact of the energized time-delay relay KT1 connected to the control relay FB. For illustration, the function of the control relay FB is to receive signals from the first intermediate relay KA1 and the energized time-delay relay KT1 and provide corresponding feedback. Its working principle is as follows: when the normally open contacts of the first intermediate relay KA1 and the energized time-delay relay KT1 are closed, the two contacts FB-1 and FB-2 of the control relay FB will conduct. Contacts FB-1 and FB-2 are located in the circuit of the lighting alarm component and are used as the overall output control for the lighting alarm. Conversely, to disconnect contacts FB-1 and FB-2, the normally open contact of the energizing delay relay KT1 and the normally open contact of the first intermediate relay KA1 must be disconnected sequentially. If only the normally open contact of the energizing delay relay KT1 is disconnected without disconnecting the normally open contact of the first intermediate relay KA1, contacts FB-1 and FB-2 will still be conductive. This is a characteristic inherent to the control relay FB itself. (See reference...) Figure 3 .

[0029] Light alarm component: See Figures 1-3The system includes an alarm light HL2, a second intermediate relay KA2, and a self-reset button SB1. The alarm light HL2 and the second intermediate relay KA2 are connected in parallel. The normally closed contact of the second intermediate relay KA2 is connected in series with the alarm light HL2. The normally open contact of the second intermediate relay KA2 is connected in parallel with the self-reset button SB1. Both the normally open contact of the second intermediate relay KA2 and the self-reset button SB1 are connected in series with the second intermediate relay KA2. The output bus of the light alarm assembly also has a contact of a control relay FB connected in series. For illustration, when there is no alarm signal, the normally open contact of the intermediate relay KA2, the self-reset button SB1, and the two contacts of the control relay FB (contacts FB1 and FB2) are open, so the second intermediate relay KA2 and the alarm light HL2 are not conducting. When contact FB1 and contact FB2 are connected, the alarm light HL2 will conduct. When staff want to reset the alarm, pressing the self-reset button SB1 will activate the coil of the second intermediate relay KA2. This will open the normally closed contact of KA2, deactivating the alarm light HL2 and extinguishing it. Conversely, the normally open contact of KA2 will close, keeping KA2 in a continuously conducting state, thus achieving self-locking of KA2. A diagram illustrating the self-locking state of KA2 can be found [link to diagram]. Figure 3 .

[0030] Voice alarm component: See Figures 1-4 The system includes a voice alarm integrated unit and a control unit located inside the unit. The control unit includes multiple voice alarm outputs connected in parallel. Generally, the unit also includes a speaker mounted on the outer wall of the chassis 1. All voice alarm outputs are connected to the speaker and amplify the alarm sounds. For illustration, the control unit can be an embedded control chip with an internal judgment program. Upon receiving a certain alarm signal, the control unit can trigger the corresponding voice alarm output to emit a signal, causing the voice alarm integrated unit to broadcast a voice alarm. Different voice alarm content can typically be set according to different types of faults, and the voice triggering method, number of broadcasts, and broadcast frequency can be set accordingly based on the alarm situation.

[0031] Circuit breaker: See Figures 1-3 The input bus of the signal processing component is connected in series with a first circuit breaker QF2, and the input bus of the light alarm component is connected in series with a second circuit breaker QF3. The input bus of the audible and visual alarm module is connected in series with a third circuit breaker QF4. For illustrative purposes, the first circuit breaker QF2, the second circuit breaker QF3, and the third circuit breaker QF4 all serve as trip protection, used to disconnect the corresponding circuit in the event of a short circuit or leakage.

[0032] Constant current source: See Figures 1-3 The audible and visual alarm module also includes a constant current source that forms a circuit with the power supply, and the output of the constant current source serves as the power supply for the voice alarm component. For illustration, the constant current source provides a stable DC current to the voice alarm component, with an input voltage of AC220V 50HZ (mains power) and an output voltage of DC24V 1.25A 30W.

[0034] In this embodiment, the chassis 1 is rectangular in shape.

A main circuit breaker QF1 is provided in the input bus. The delay time of the power-on delay relay KT1 is approximately 5 seconds. The control unit has a total of 7 voice alarms, with scenarios including: system fault, ground flooding alarm, communication fault, system flooding alarm, water accumulation in puddles alarm, abnormal system water ingress, and abnormal system output pressure.
