Description

Technical Field

[0001] This utility model relates to the field of public facility testing technology, specifically to an electromechanical testing terminal for public service facilities. Background Technology

[0002] Public service facility electromechanical equipment is the core support system ensuring the normal operation of various public spaces, covering multiple areas such as water supply and drainage, heating and ventilation, power supply, elevator transportation, and fire protection and security. The stable operation of this equipment directly affects the public's daily life, work, and travel experience. For example, elevators and escalators in transportation hubs ensure efficient personnel flow, HVAC systems in large venues maintain a suitable indoor environment, and municipal water supply and drainage equipment ensures residents' basic domestic water use and sewage discharge. In grassroots governance scenarios, the electromechanical equipment in public spaces such as communities and streets is even more closely related to residents' lives, and its stable operation is the foundation for efficient grassroots governance—from water and electricity supply equipment that ensures residents' daily water and electricity needs to fire protection and security systems that maintain community safety, all need to be kept in good working order at all times. Therefore, in design and operation and maintenance, the principles of safety, reliability, and energy efficiency must be followed, and regular inspections, intelligent monitoring, and timely maintenance must be implemented to ensure that the equipment is in good operating condition.

[0003] In the field of electromechanical testing of public service facilities, testing terminals need to be flexibly configured with testing modules according to different scenarios to adapt to the monitoring needs of various equipment such as air conditioners, elevators, and self-service terminals. In grassroots governance scenarios, staff often need to inspect community pump rooms, elevators in corridors, public area lighting, and fire protection facilities, requiring testing terminals to adapt to these diverse equipment testing needs. However, to meet this requirement, the terminals are usually equipped with multiple types of testing modules to adapt to the testing work of electromechanical equipment in different scenarios. This results in a large overall weight for the terminals, causing inconvenience for grassroots staff in daily carrying and on-site operation. Utility Model Content

[0027] 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.

[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1

[0030] A preferred embodiment of the electromechanical testing terminal for public service facilities provided by this utility model is, for example... Figure 1-6 As shown: The electromechanical testing terminal for public service facilities includes: a housing 1, and a cover 2 fixedly installed on the top of the housing 1;

[0031] Detection component 3 is disposed inside the housing 1;

[0032] The detection component 3 includes a sound collection part 31 and a vibration frequency detection part 32, both of which are located inside the outer casing 1.

[0033] The sound collection unit 31 includes a housing 311, a cover 312 fixedly installed on the top of the housing 311, a preamplifier 313 fixedly installed inside the housing 311, an A / D converter 314 electrically connected to one side of the preamplifier 313, a display 315 fixedly installed on the top of the cover 2, a sound sensor probe 316 fixedly installed inside the left side of the housing 311, heat dissipation holes 317 are provided on both sides of the housing 1, the housing 311 is located inside the housing 1, one side of the housing 311 penetrates through the housing 1 and extends into the interior of the housing 1, the preamplifier 313 is electrically connected to the sound sensor probe 316, and the A / D converter 314 is electrically connected to the display 315.

[0034] The vibration frequency detection unit 32 includes a base block 321, which is located inside the housing 1. A piezoelectric accelerometer 322 is fixedly installed on the bottom of the base block 321. A charge amplifier 323 is electrically connected to the top of the piezoelectric accelerometer 322. A power supply box 324 is fixedly installed inside the housing 1. A bottom hole 325 is opened at the bottom of the housing 1. The base block 321 is fixedly installed at the bottom of the housing 311 and is located inside the bottom hole 325. An A / D converter 314 is fixedly installed inside the housing 311. The charge amplifier 323 is electrically connected to the display 315. The power supply box 324 is electrically connected to the display 315.

[0035] This terminal is suitable for detecting air conditioner outdoor units in public areas. The sound sensor probe 316 uses an omnidirectional microphone, which can capture noise within a 360° range around the air conditioner outdoor unit. By holding the handle 411, the detection terminal is moved to the vicinity of the air conditioner outdoor unit at a horizontal distance of 1-1.5 meters. The microphone converts sound wave vibrations into electrical signals, which are amplified by the preamplifier 313 (adjustable gain, range 0-60dB). The analog signal is then converted into a digital signal by the A / D converter 314 (sampling rate 44.1kHz) and transmitted to the display 315. The equivalent continuous A-weighted sound level is calculated according to the acoustic algorithm set in the display 315, which is the average noise value over a certain period of time (usually 1 minute) and directly displayed as "decibels". If it exceeds the decibel level when the air conditioner outdoor unit is operating normally, it indicates that the air conditioner outdoor unit is malfunctioning.

[0036] When detecting the vibration frequency of the outdoor unit of the air conditioner, the terminal is placed on the top of the outdoor unit casing. The piezoelectric accelerometer 322 is in contact with the casing. The sensor converts the mechanical vibration of the air conditioner casing into an electrical signal, which is then converted into a voltage signal (0-10V) by the charge amplifier 323. The terminal performs spectrum analysis on the signal through Fourier transform (FFT) to extract the main frequency components of the vibration and displays the detected vibration frequency on the display 315.

[0037] When neighborhood disputes arise due to the use of public mechanical and electrical equipment in the community, the terminal can serve as an objective basis to assist in mediation. For example, if two residents are arguing over the noise of an air conditioner outdoor unit in a public area, the community mediator can bring the terminal to the site to test the decibel level and vibration frequency of the outdoor unit, display the data to both parties, clarify whether the noise is due to equipment failure, quickly determine responsibility, and promote repairs to prevent the conflict from escalating.

[0038] Example 2

[0039] Based on Embodiment 1, a preferred embodiment of the electromechanical testing terminal for public service facilities provided by this utility model is, for example... Figure 1-6 As shown: Mounting component 4 is located inside the outer casing 1;

[0040] The mounting component 4 includes a mounting part 1 41 and a mounting part 2 42. The mounting part 1 41 is located on the top of the outer shell 1, and the mounting part 2 42 is located inside the outer shell 1.

[0041] Mounting part 1 41 includes a handle 411, which is fixedly mounted on the top of the cover 2. The two sides of the middle part of the cover 2 are fixedly mounted with a first locking block 412. The two sides of the middle part of the outer shell 1 are fixedly mounted with a second locking block 413. The two sides of the outer shell 1 are provided with a sleeve 414. The two sides of the outer shell 1 are provided with a sliding groove 415. The first locking block 412 and the second locking block 413 are both locked inside the sleeve 414. One side of the sleeve 414 is movably mounted inside the sliding groove 415.

[0042] Installation part 2 42 includes a fixing block 421, which is located inside the outer shell 1. A support 422 is fixedly installed on the inner wall of the outer shell 1. A U-shaped rod 423 is movably installed inside the support 422. Round blocks 424 are fixedly installed at both ends of the bottom of the U-shaped rod 423. A spring 425 is fixedly connected to the top of the round blocks 424. A sleeve 426 is provided on the top of the support 422. The fixing block 421 is fixedly installed on both sides of the bottom of the box 311. The support 422 is located on the top of the fixing block 421. The two ends of the bottom of the U-shaped rod 423 pass through the sleeve 426, the support 422 and the fixing block 421 in sequence. The two ends of the bottom of the U-shaped rod 423 extend into the interior of the fixing block 421. The U-shaped rod 423 is movably installed between the fixing block 421, the support 422 and the sleeve 426. One end of the spring 425 is fixedly connected to the bottom of the sleeve 426. The sleeve 426 is fixedly installed to the inner wall of the outer shell 1.

[0043] The cover 2 is fixedly installed with a first locking block 412 on both sides, and the outer shell 1 is fixedly installed with a second locking block 413 on both sides. The cover 2 is placed on top of the outer shell 1 so that the first locking block 412 and the second locking block 413 overlap. Then the sleeve 414 is fitted and engaged with the first locking block 412 and the second locking block 413, and the installation between the cover 2 and the outer shell 1 is completed.

[0044] The housing 311 is located inside the outer shell 1. The left side of the housing 311 penetrates the outer shell 1 and extends to the outside of the outer shell 1. The bottom block 321 fixedly installed at the bottom of the housing 311 is located inside the bottom hole 325, so that the housing 311 can only move laterally inside the outer shell 1. Fixing blocks 421 are fixedly installed on both sides of the housing 311. The two ends of the bottom of the U-shaped rod 423 are located inside the fixing blocks 421 to limit the fixing blocks 421. The housing 311 is installed inside the outer shell 1.

[0045] Lifting the U-shaped rod 423 upwards causes the spring 425 to contract, moving both ends of the bottom of the U-shaped rod 423 out of the fixing block 421. At this point, the housing 311 can be disassembled from the housing 1 for easy replacement with other types of housing modules.

[0046] Example 3

[0047] Based on Embodiments 1 and 2, a preferred embodiment of the electromechanical testing terminal for public service facilities provided by this utility model is as follows: Figure 1-6 As shown: The power supply box 324 provides power support for the entire testing terminal. The outer shell 1 has heat dissipation holes 317 on both sides, which facilitates heat dissipation inside the outer shell 1 and also reduces the weight of the outer shell 1. The terminal is equipped with only a single testing module to perform electromechanical equipment testing in a single scenario. If it is necessary to test electromechanical equipment in other scenarios, only the testing module needs to be replaced. This avoids integrating multiple testing modules into the terminal, making the terminal lightweight and easy to carry.

[0048] The internal detection component 3 of the terminal can be replaced to make the terminal suitable for other scenarios. For example, it can be replaced with a housing module that internally contains an ARM9-based microprocessor, voltage and current sensors, and an RF probe. The microprocessor acquires the operating parameters of the self-service terminal, analyzes and processes them, displays the operating parameters, saves data periodically, and transmits the collected data to the display 315 through the communication interface. The voltage and current sensors are used to detect the power supply parameters of the self-service terminal. By collecting the terminal's operating voltage and current, it can determine whether the power module is working properly and whether there are problems such as overload or short circuit. For example, when the voltage fluctuation exceeds a certain range or the current increases abnormally, it may indicate that the terminal is faulty. The RF probe can monitor the RF field strength of the card reader. If the field strength is lower than 1.2V / m, it may be that the card reader antenna is damaged or the power module is faulty, resulting in the inability to recognize the ID card. If the field strength fluctuates drastically (>±0.5V / m), it is determined to be RF circuit interference.

[0049] In places such as street government service centers and community convenience service stations, terminals equipped with this type of box module can detect self-service terminals and ID card readers. Once a problem such as equipment malfunction or recognition failure is detected, an early warning will be immediately triggered and pushed to the maintenance team to ensure that residents can smoothly handle social security inquiries, certificate printing and other services, improve the convenience of government services and reduce public complaints caused by equipment problems.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
