[0009] Figure 1 A circuit diagram of an audible and visual alarm device provided in an embodiment of this application. In some embodiments, such as Figure 1 As shown, an embodiment of this application provides an audible and visual alarm device 100, comprising: First interface 101, second interface 102 and third interface 103; The first switch transistor 104, the first interface 101 and the second interface 102 are respectively connected to the first end of the first switch transistor 104; The logic processor 105 has a first terminal connected to the second terminal of the first switching transistor 104, and the third terminal of the first switching transistor 104 is grounded. Relay 106, one end of which is connected to the second end of logic processor 105, and the other end of which is connected to third interface 103.

[0010] In this embodiment, an audible and visual alarm device 100 is proposed, which is a device capable of emitting audible and visual alarms.

[0011] For example, the audible and visual alarm device 100 can be an alarm device for an air compressor, which issues an audible and visual alarm in the event of a malfunction in the air compressor.

[0012] The audible and visual alarm device 100 includes a first interface 101, a second interface 102, and a third interface 103, wherein the first interface 101 and the second interface 102 are signal input interfaces, and the third interface 103 is a signal output interface.

[0013] For example, the first interface 101 and the second interface 102 can be 3.5mm standard stereo audio interfaces, serving as signal input and monitoring ports for each other. During debugging, the signal can be input through the first interface 101 and monitored or bypassed through the second interface 102. If monitoring is not required, only one interface needs to be retained.

[0014] For example, the third interface 103 is a control interface, wherein terminal 2 is a common terminal, terminals 2 and 3 are normally open contacts, and terminals 1 and 2 are normally closed contacts. It can be selectively connected to the control terminal of an audible and visual alarm, allowing selection to either activate or deactivate the alarm. The third interface 103 can output various alarms, including delayed alarm with immediate reset, immediate alarm with delayed reset, and immediate alarm with manual reset.

[0015] The audible and visual alarm device 100 also includes a first switch tube 104, and a first interface 101 and a second interface 102 are connected to the first end of the first switch tube 104.

[0016] For example, the first switching transistor 104 can be a triode.

[0017] The audible and visual alarm device 100 also includes a logic processor 105, the first terminal of which is connected to the second terminal of the first switching transistor 104, and the third terminal of the first switching transistor 104 is grounded.

[0018] For example, the logic processor 105 can be a logic chip of model CD4011BE.

[0019] The audible and visual alarm device 100 also includes a relay 106, one end of which is connected to the second end of the logic processor 105, and the other end is connected to the third interface 103.

[0020] For example, relay 106 may include a coil and a contact switch, and relay 106 is in a normally open state.

[0021] For example, an industrial control computer's audio signal source is used to control the relay 106, providing an alarm trigger signal. This achieves the goal of building an audible and visual alarm system with a small number of components, thus improving the centralized monitoring and alarm system. The type of audible and visual alarm is unrestricted; it can be independently powered (connected only to the control terminal) or share a power supply with the drive unit. This compensates for the shortcomings of ordinary speakers in outputting alarm audio, increasing the alertness. Combined with the host computer screen, it facilitates the location of alarm points, enabling operators to react quickly and make subsequent work arrangements.

[0022] Traditional alarm devices rely on field control cabinets, and the audible and visual alarms are led out by hard wires, making them inconvenient to relocate. If the audible and visual alarm system is rebuilt in the central monitoring room in the same way as the original station, it will consume huge equipment and time costs. However, the audible and visual alarm device 100 in this embodiment does not rely on a field control cabinet, which simplifies the circuit structure of the audible and visual alarm device 100 and reduces the device cost.

The first capacitor 109 has one end connected to the other end of the first resistor 107 and the second resistor 108, and the other end connected to the first end of the first switch transistor 104.

[0024] In this embodiment, the audible and visual alarm device 100 further includes a first resistor 107, a second resistor 108, and a first capacitor 109.

When the first switch 113 is set to end 1 and the second switch 114 is set to end 1, if there is a signal input, the relay 106 will operate. When the signal disappears, the relay 106 will automatically recover.

[0034] When the first switch 113 is set to terminal 3 and the second switch 114 is set to terminal 1, the relay 106 will operate regardless of whether there is a signal input. When the second switch 114 is set to terminal 3, the relay 106 will not operate regardless of whether there is a signal input or the position of the first switch 113.
