Description

Technical Field

[0001] The present application relates to the field of alarm control, and in particular to an integrated sound and light warning system. Background Art

[0002] Audible and visual alarm is also called sound and light alarm, which is set to meet customers' special requirements for alarm volume and installation location. It can send out both sound and light alarm signals at the same time, and is often used in iron and steel metallurgy, telecommunication towers, lifting machinery, engineering machinery, ports and docks, transportation, wind power generation, ocean-going ships and other industries; it is an accessory product in industrial alarm systems.

[0003] In the prior art, common sound and light alarms mainly include a shell, in which an LED light, a buzzer, a control unit, etc. are installed. The sound and light alarm is often used in conjunction with a sensor. The control unit is connected to the sensor through a data cable or a wireless network module signal. The control unit receives the sensing signal output by the sensor and compares it. When the signal is abnormal, the LED light can be controlled to flash and the buzzer can be controlled to sound a warning sound, so as to achieve the technical effect of real-time monitoring and alarm.

[0004] However, common sound and light alarms do not emit light or sound unless an abnormal signal is detected. After installation, operators often need to use an external remote control to test the sound and light alarm. After installation, it is difficult for workshop workers to determine whether the sound and light alarm is damaged, which is inconvenient to use and needs improvement. Utility Model Content

[0005] In order to facilitate operators to grasp the operating status of the sound and light alarm in real time, the present application provides an integrated sound and light warning system.

[0006] The integrated sound and light warning system provided by the present application adopts the following technical solution:

[0007] An integrated sound and light warning system includes a sound and light alarm body, in which a buzzer, a first prompt light, a second prompt light and a driving circuit are fixedly installed; the driving circuit includes:

[0008] The sampling circuit has an input terminal connected to the output terminal signal of the sensor, and is used to collect the sensing signal and output the sampling voltage;

[0009] A single chip microcomputer, the input end of which is electrically connected to the sampling circuit, for receiving and comparing the sampling voltage, and outputting a low level signal when the sampling voltage is lower than a set value, and outputting a high level signal when the sampling voltage is higher than the set value;

[0010] The output end of the single-chip microcomputer is controlled and connected with the first prompt light, the second prompt light and the input end of the buzzer. The first prompt light receives the low-level signal and emits light; the buzzer receives the low-level signal and emits a first prompt sound, and receives the high-level signal and emits a second prompt sound; the second prompt light receives the high-level signal and emits light.

[0011] By adopting the above technical solution, when the operator has installed the sound and light alarm and turned on the power, the sampling circuit collects the induction signal output by the sensor and outputs the sampling voltage. After receiving the sampling voltage, the single-chip microcomputer compares it and outputs a low-level signal when the sampling voltage is normal. At this time, the buzzer emits a first prompt sound and the first prompt light is lit. The operator can determine that the sound and light alarm is operating normally and the induction signal collected by the sensor is normal, and it can be determined that the sound and light alarm has not issued an alarm; when the sensor outputs an abnormal induction signal and the sampling circuit outputs an abnormal sampling voltage, the single-chip microcomputer outputs a high-level signal, the first prompt light stops emitting light, the second prompt light is emitting light, and the buzzer emits a second prompt sound, and the sound and light alarm issues an alarm, which can achieve the technical effect of reporting an error or prompting the on-site operator. In actual use, the on-site operator can judge whether the sound and light alarm is operating normally by whether the buzzer emits the first prompt sound and whether the first prompt light is lit. The installer can also judge whether the sound and light alarm is installed by the sound emitted by the buzzer and the state of the first prompt light, which can effectively facilitate the installer and operator to judge the state of the sound and light alarm.

[0012] Preferably, the single chip microcomputer comprises a first output terminal, the first output terminal is signal-connected to a first transistor Q1, and the output terminal of the first transistor Q1 is control-connected to the input terminal of the buzzer;

[0013] The first transistor Q1 receives the low level signal and controls the buzzer to emit the first prompt sound, and receives the high level signal and controls the buzzer to emit the second prompt sound.

[0014] By adopting the above technical solution, the buzzer can be controlled to emit the first prompt sound or the second prompt sound according to the high level signal or the low level signal output by the single chip microcomputer through the first transistor Q1.

[0015] Preferably, the single chip computer includes a second output terminal, the second output terminal is signal-connected to a second transistor Q2, and the output terminal of the second transistor Q2 is control-connected to the input terminals of the first prompt light and the second prompt light;

[0016] The second transistor Q2 receives the low level signal and controls the first indication light to emit light, and receives the high level signal and controls the second indication light to emit light.

[0017] By adopting the above technical solution, the first transistor Q1 can control the first indication light or the second indication light to emit light according to the high level signal or the low level signal output by the single chip microcomputer.

[0018] Preferably, it also includes a mounting base, and the sound and light alarm body is detachably connected to the mounting base.

[0019] By adopting the above technical solution, during the actual installation process, the installer can pre-fix the mounting base on the rack of the structure or equipment, and then fix the sound and light alarm through the mounting base. During actual use, when the sound and light alarm fails, the operator can disassemble the sound and light alarm body and reinstall it after inspection, without repeatedly disassembling the installation screws, etc., which can improve the convenience of the operator to disassemble and assemble the sound and light alarm body and perform inspection operations on the sound and light alarm body.

[0020] Preferably, the sound and light alarm body comprises a mounting portion, two mounting rods are fixedly connected to the side wall of the mounting portion, and a mounting groove adapted to the mounting portion is provided on the mounting seat;

[0021] Two clamping grooves are arranged on the inner groove wall of the installation groove, and the two installation rods are respectively detachably installed in the two clamping grooves.

[0022] By adopting the above technical solution, through the mutual matching and use of the card slot and the installation rod, the technical effect of detachable installation between the sound and light alarm body and the installation slot can be achieved.

[0023] Preferably, the slot includes an insertion portion for the installation rod to extend into, a terminal end of the insertion portion is connected to a clamping portion, a direction of the clamping portion is perpendicular to a direction of the insertion portion, and the installation rod is clamped and fixed in the clamping portion.

[0024] By adopting the above technical solution, during the process of installing the sound and light alarm body on the mounting base, the operator can preliminarily extend the mounting rod into the interior of the mounting groove through the insertion portion on the card slot, and then the operator rotates the sound and light alarm body to rotate the connecting rod into the card connection portion. The two groove walls opposite to each other of the card connection portion restrict the position of the mounting rod, thereby achieving the fixation of the mounting rod and further achieving the detachable installation and fixation of the sound and light alarm body.

[0025] Preferably, a spring sheet is fixedly connected to the bottom of the mounting groove, and the spring sheet is tightly pressed between the mounting portion and the bottom of the mounting groove.

[0026] By adopting the above technical solution, the spring sheet forms elastic support for the mounting part of the sound and light alarm, so that the mounting rod on the mounting part can be tightly pressed against the inner groove wall of the clamping part, which can effectively improve the installation stability between the sound and light alarm and the mounting base.

[0027] In summary, the integrated sound and light warning system of the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the combination and use of sensors, sampling circuits, single-chip computers, buzzers, first prompt lights and second prompt lights, the buzzer can be controlled to emit a first prompt sound (i.e., a beeping sound) in a normal state and when powered on, and the first prompt light can be controlled to light up at the same time, which can remind the installer or on-site operator that the sound and light alarm is operating normally; when the buzzer emits an alarm sound and the second prompt light lights up, the on-site operator can determine that the sound and light alarm has issued an alarm; when the buzzer does not emit a sound and the first prompt light and the second prompt light are not operating, the operator (or installer) can determine that the sound and light alarm has a fault and needs to be repaired and maintained, which can improve the convenience of the operator to grasp the operating status of the sound and light alarm;

[0029] 2. Through the card slot in the mounting base and the mounting rod on the sound and light alarm body, the technical effect of detachable installation between the mounting base and the sound and light alarm body can be achieved, which is convenient for operators to disassemble and assemble the sound and light alarm when inspecting and maintaining the sound and light alarm.

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] Example

[0036] The present application embodiment discloses an integrated sound and light warning system. Figure 1 , including a sound and light alarm body 1, in which a buzzer 2, a first prompt light 3, a second prompt light 4 and a driving circuit are fixedly installed.

[0037] Reference Figure 2 The driving circuit includes: a sampling circuit 5, whose input end is signal-connected to the output end of the sensor, for collecting the sensing signal and outputting the sampling voltage; a single-chip microcomputer, whose input end is electrically connected to the sampling circuit 5, for receiving and comparing the sampling voltage, and outputting a low-level signal when the sampling voltage is lower than the set value, and outputting a high-level signal when the sampling voltage is higher than the set value.

[0038] The output end of the single-chip microcomputer is controlled and connected to the first prompt light 3 (emitting green light), the second prompt light 4 (emitting yellow light) and the input end of the buzzer 2. The first prompt light 3 receives a low-level signal and emits light; the buzzer 2 receives a low-level signal and emits a first prompt sound (a beeping sound), and receives a high-level signal and emits a second prompt sound (a humming sound); the second prompt light 4 receives a high-level signal and emits light. Generally speaking, in industrial production and manufacturing, green light represents safety and normal production, yellow light represents pause and waiting, and red light represents accidents and emergencies. The single-chip microcomputer needs to control the first prompt light 3 and the second prompt light 4 to emit different light sources to achieve the effect of visual prompts.

[0039] When the operator has installed the sound and light alarm and turned on the power, the sampling circuit 5 collects the sensing signal output by the sensor and outputs the sampling voltage. The single-chip microcomputer receives the sampling voltage and compares it, and outputs a low-level signal when the sampling voltage is normal. At this time, the buzzer 2 emits a first prompt sound, and the first prompt light 3 is lit. The operator can determine that the sound and light alarm is operating normally and the sensing signal collected by the sensor is normal, and it can be determined that the sound and light alarm has not issued an alarm; when the sensor outputs an abnormal sensing signal and the sampling circuit 5 outputs an abnormal sampling voltage, the single-chip microcomputer outputs a high-level signal, the first prompt light 3 stops emitting light, the second prompt light 4 emits light, and the buzzer 2 emits a second prompt sound, and the sound and light alarm issues an alarm, which can achieve the technical effect of reporting an error or prompting the on-site operator.

[0040] During actual use, on-site operators can judge whether the sound and light alarm is operating normally by whether the buzzer 2 emits the first prompt sound and whether the first prompt light 3 is lit. Installers can also judge whether the sound and light alarm is installed by the sound emitted by the buzzer 2 and the status of the first prompt light 3, which can effectively facilitate installers and operators to judge the status of the sound and light alarm.

[0041] Reference Figure 2 The single chip microcomputer includes a first output terminal, namely, pin P12, the pin P12 is signal-connected to the first transistor Q1, the output terminal of the pin P12 is electrically connected to the base of the first transistor Q1, and the collector of the first transistor Q1 is control-connected to the input terminal of the buzzer 2.

[0042] The first transistor Q1 receives a low level signal and controls the buzzer 2 to emit a first prompt sound, and receives a high level signal and controls the buzzer 2 to emit a second prompt sound.

[0043] The first transistor Q1 can control the buzzer 2 to emit a first prompt sound or a second prompt sound according to the high level signal or the low level signal output by the single chip microcomputer.

[0044] Reference Figure 2 The single chip computer includes a second output terminal, namely, pin P14. The pin P14 signal is connected to the second transistor Q2. The output terminal of the pin P14 is electrically connected to the base of the second transistor Q2. The collector of the second transistor Q2 is electrically connected to the input terminals of the first prompt light 3 and the second prompt light 4.

[0045] The second transistor Q2 receives a low level signal and controls the first indication light 3 to emit light, and receives a high level signal and controls the second indication light 4 to emit light.

[0046] The first transistor Q1 can control the first indication light 3 or the second indication light 4 to emit light according to the high level signal or the low level signal output by the single chip microcomputer.

[0047] It also includes a mounting base 6, and the sound and light alarm body 1 is detachably connected to the mounting base 6.

[0048] During the actual installation process, the installer can pre-fix the mounting base 6 on the rack of the structure or equipment, and then fix the sound and light alarm through the mounting base 6. During actual use, when the sound and light alarm fails, the operator can disassemble the sound and light alarm body 1, repair it, and then reinstall it, without repeatedly disassembling the installation screws, etc., which can improve the convenience of the operator to disassemble and assemble the sound and light alarm body 1 and perform maintenance operations on the sound and light alarm body 1.

[0049] Reference Figure 1 and Figure 2 The body 1 of the sound and light alarm includes a mounting portion 11, on the side wall of which two mounting rods 12 are fixedly connected, and a mounting seat 6 is provided with a mounting groove 61 adapted to the mounting portion 11; the inner groove wall of the mounting groove 61 is provided with two card slots 62, and the two mounting rods 12 are respectively detachably mounted in the two card slots 62. By matching and using the card slots 62 and the mounting rods 12, the technical effect of detachable installation between the body 1 of the sound and light alarm and the mounting groove 61 can be achieved.

[0050] Reference Figure 3 The slot 62 includes an insertion portion 621 for the installation rod 12 to extend into, and the end of the insertion portion 621 is connected to a clamping portion 622 . The direction of the clamping portion 622 is perpendicular to the direction of the insertion portion 621 , and the installation rod 12 is clamped and fixed in the clamping portion 622 .

[0051] During the process of installing the sound and light alarm body 1 on the mounting base 6, the operator can first extend the mounting rod 12 into the interior of the mounting groove 61 through the insertion portion 621 on the card slot 62, and then the operator rotates the sound and light alarm body 1 to rotate the connecting rod into the card connection portion 622. The two opposite groove walls of the card connection portion 622 restrict the position of the mounting rod 12, thereby achieving the fixation of the mounting rod 12 and further achieving the detachable installation and fixation of the sound and light alarm body 1.

[0052] Reference Figure 1 A spring piece 63 is fixedly connected to the bottom of the mounting groove 61 , and the spring piece 63 is tightly pressed between the mounting portion 11 and the bottom of the mounting groove 61 .

[0053] The spring piece 63 forms elastic support for the mounting portion 11 of the sound and light alarm, so that the mounting rod 12 on the mounting portion 11 can be tightly pressed against the inner groove wall of the clamping portion 622, which can effectively improve the installation stability between the sound and light alarm and the mounting base 6.
