Description

Technical Field

[0001] This utility model relates to the field of signal display device technology, and more specifically, to a signal display device for a multi-frequency combiner. Background Technology

[0002] A signal display device is a device or system that can receive, process, and display various signal information in an intuitive manner. It can convert different forms of signals, such as electrical signals, optical signals, and digital signals, into information that is easy for people to understand through visual, auditory, or other sensory means, so that operators and users can interpret this information in a timely manner and make corresponding decisions. Signal display devices are mainly used in industrial production, transportation, and communication fields.

[0003] A search revealed that publication number CN220669045U discloses a multi-signal simultaneous display device, comprising: a display device base and a display body; the display body is fixedly installed on the top of the display device base, and the display body includes three external screens in the shape of an equilateral triangular cylinder, and three internal screens in the shape of an equilateral triangular cylinder are lifted and lowered in the center of the external three screens. This device can realize multi-screen selection, and is small in size, simple to operate, and practical in function. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:

[0004] Traditional multi-frequency combiners rely solely on simple digital displays to show the strength of the combiner's transmitted signal, resulting in a limited range of information. Furthermore, they cannot provide timely data feedback to maintenance personnel when the combiner signal malfunctions, causing delays in combiner repairs. Additionally, after prolonged use, existing multi-frequency combiner signal display devices generate thermal noise from internal electronic components due to heat accumulation, interfering with accurate signal display and rendering the displayed data inaccurate.

[0005] Therefore, a signal display device for a multi-frequency combiner is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a signal display device for a multi-frequency combiner to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a signal display device for a multi-frequency combiner, comprising a signal processing component, a signal expression component, a mounting mechanism, and a combiner body. The mounting mechanism is mounted on the top of the combiner body, and the signal processing component is placed on the upper inner wall of the mounting mechanism. The signal expression component is placed on the top of the signal processing component. The mounting mechanism includes a limiting component and a fixing component, and the fixing component is mounted on the side of the limiting component.

[0008] Preferably, the signal processing component includes a signal strength detection chip, an analog-to-digital converter, and a control panel, with the analog-to-digital converter placed on the side of the signal strength detection chip and the control panel placed on top of the analog-to-digital converter.

[0009] Preferably, the signal expression component includes a first indicator light, a second indicator light, and a buzzer, wherein the second indicator light is placed on the side of the first indicator light, and the buzzer is placed on the side of the second indicator light away from the first indicator light.

[0010] Preferably, the limiting component includes a housing, a connecting plate, heat dissipation holes and heat sinks, and the housing has heat dissipation holes drilled in the side wall, heat sinks are installed on the side of the housing, and the connecting plate is placed on the side of the housing away from the heat sinks.

[0011] Preferably, the fixing component includes a fixing bolt, a first anti-loosening washer and a second anti-loosening washer, wherein the first anti-loosening washer is placed on the outer diameter surface of the fixing bolt, and the second anti-loosening washer is placed below the first anti-loosening washer.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with existing technologies, this signal display device for a multi-frequency combiner displays and responds to the signals emitted by the multi-frequency combiner in a timely manner through signal expression components. Compared with traditional electronic screens that display signal strength, the indicator lights provide a more intuitive display effect. Maintenance personnel can judge the signal strength simply by observing the color of the indicator lights. Furthermore, the buzzer can alert maintenance personnel to any abnormal signal conditions, enabling them to promptly inspect and repair the combiner.

[0014] Compared with existing technologies, the signal display device of this multi-frequency combiner dissipates heat from inside the housing in a timely manner through the heat sink and heat dissipation holes in the limiting component, effectively reducing the low thermal noise inside the housing and making the signal display more accurate. This improves the display quality and stability of the signal display device. High temperature is also a major factor causing the aging of electronic components. The limiting component dissipates heat from inside the housing in a timely manner, thereby extending the service life of the components and even the entire device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] As attached Figures 1 to 4 The signal display device of a multi-frequency combiner shown includes a signal processing component 1, a signal expression component 2, a mounting mechanism 3, and a combiner body 4. The mounting mechanism 3 is mounted on the top of the combiner body 4. The signal processing component 1 is placed on the upper inner wall of the mounting mechanism 3. The signal expression component 2 is placed on the top of the signal processing component 1. The mounting mechanism 3 includes a limiting component 5 and a fixing component 6. The fixing component 6 is mounted on the side of the limiting component 5.

[0022] Specifically: When the staff installs the signal display device onto the combiner, they first need to connect the signal processing component 1 and the signal expression component 2 with wires, and then fix them to the limit component 5 of the installation mechanism 3 with bolts. Then, the limit component 5 and the combiner body 4 are connected and fixed by the fixing component 6. After the signal display device is installed, the staff opens the combiner body 4. At this time, the combiner body 4 will collect the surrounding signals, and then the signal processing component 1 will process the collected signals and display them through the signal expression component 2. If the signal strength is not up to standard, the signal processing component 1 will upload the data to the monitoring platform, and the signal expression component 2 will sound an alarm, so that the maintenance personnel can find the signal problem of the combiner as soon as possible and deal with it. Example 2

[0023] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0024] In a preferred embodiment, the signal processing component 1 includes a signal strength detection chip 7, an analog-to-digital converter 8, and a control panel 9. The analog-to-digital converter 8 is model AD652, which is a voltage-frequency converter type. It converts analog voltage into pulse signals, and the frequency of its output pulse signal is proportional to the magnitude of the input voltage, which facilitates data analysis by the control panel 9. It is often used in digital control systems that require high-resolution analog-to-digital conversion and have requirements for signal anti-interference capability and long-distance transmission. The analog-to-digital converter 8 is placed on the side of the signal strength detection chip 7, and the control panel 9 is placed on top of the analog-to-digital converter 8. When the signal processing component 1 is running, the signal strength detection chip 7 converts the radio frequency signal output by the combiner body 4 into a quantifiable DC voltage signal. Then, the analog-to-digital converter 8 converts the analog voltage signal output by the signal strength detection chip 7 into a digital signal for the control panel 9 to read and analyze. After the control panel 9 finishes analyzing the data, it controls the signal expression component 2 to display the corresponding strength of the signal output by the combiner body 4.

[0025] In a preferred embodiment, the signal expression component 2 includes a first indicator light 10, a second indicator light 11, and a buzzer 12. The buzzer 12 is a common small passive buzzer 12, model PB-2405, which typically operates at around 5V. It requires an external drive signal of a specific frequency to produce sound. Its advantage is good sound quality, and different tones can be produced by changing the frequency of the drive signal. It is commonly used in devices that require simulating multiple sounds, such as electronic keyboards and music boxes. The second indicator light 11 is placed on the side of the first indicator light 10, and the buzzer 12 is placed on the side of the second indicator light 11 away from the first indicator light 10. When the output signal of the combiner body 4 is within the qualified threshold, the first indicator light 10 of the signal expression component 2 will light up green. When the output signal of the combiner body 4 is below the qualified threshold, the second indicator light 11 will light up red and the buzzer 12 will sound an alarm, allowing maintenance personnel to detect problems with the output signal of the combiner body 4 immediately and make timely adjustments and repairs.

[0026] In a preferred embodiment, the limiting component 5 includes a housing 13, a connecting plate 14, heat dissipation holes 15, and heat sinks 16. The side wall of the housing 13 has heat dissipation holes 15, and the heat sinks 16 are welded to the side of the housing 13. The connecting plate 14 is placed on the side of the housing 13 away from the heat sinks 16. When the worker fixes the limiting component 5 and the combiner body 4, the housing 13 containing the signal expression component 2 and the signal processing component 1 and the connecting plate 14 on the combiner body 4 need to be fixed by the fixing component 6. When the signal display device is running, the heat dissipation holes 15 on the side wall of the housing 13 and the heat sinks 16 installed on its surface can quickly cool down its interior.

[0027] In a preferred embodiment, the fixing component 6 includes a fixing bolt 17, a first anti-loosening washer 18, and a second anti-loosening washer 19. The first anti-loosening washer 18 is placed on the outer diameter surface of the fixing bolt 17, and the second anti-loosening washer 19 is placed below the first anti-loosening washer 18. When the operator needs to fix the limiting component 5 and the combiner body 4, the first anti-loosening washer 18 and the second anti-loosening washer 19 need to be placed on the outer diameter surface of the fixing bolt 17, and then the fixing bolt 17 is screwed into the limiting component 5 with a wrench to achieve the fixing between the limiting grip and the combiner body 4.

[0028] The working process of this utility model is as follows: First, when the operator installs the signal display device onto the combiner, the signal processing component 1 and the signal expression component 2 need to be connected by wires. Then, the first anti-loosening pad 18 and the second anti-loosening pad 19 of the fixing component 6 need to be placed on the outer diameter surface of the fixing bolt 17. Then, the housing 13 of the limiting component 5 and the connecting plate 14 fixed by bolts on the combiner body 4 are connected and fixed by the fixing bolt 17. After the signal display device is installed, the operator opens the combiner body 4. At this time, the combiner body 4 will collect the surrounding signals. Then, the signal strength detection chip 7 of the signal processing component 1 will convert the radio frequency signal output by the combiner body 4 into a quantifiable DC voltage signal.

[0029] The analog-to-digital converter 8 converts the analog voltage signal output by the signal strength detection chip 7 into a digital signal for the control panel 9 to read and analyze. After analyzing the data, the control panel 9 controls the signal expression component 2 to display the strength of the signal output by the combiner body 4. When the output signal of the combiner body 4 is within the qualified threshold, the first indicator light 10 of the signal expression component 2 will light up green. When the output signal of the combiner body 4 is below the qualified threshold, the second indicator light 11 will light up red and the buzzer 12 will sound an alarm, so that maintenance personnel can find the problem of the output signal of the combiner body 4 as soon as possible and make timely adjustments and repairs. During the operation of the signal display device, a lot of heat is generated inside. The heat dissipation holes 15 on the side wall of the housing 13 and the heat sink 16 installed on its surface can quickly cool down the inside. The above is the working principle of the signal display device of this multi-frequency combiner.
