Description

Technical Field

[0001] This utility model belongs to the technical field of warning line equipment, specifically relating to a warning line with voice broadcast. Background Technology

[0002] In scenarios such as maintaining public safety, protecting evidence at the scene, or preventing personnel from entering dangerous areas, including accident scenes, crime scenes, construction restricted areas, leak and contamination areas, and power repair areas, setting up warning lines is a common and necessary measure. Warning lines are usually composed of strips printed with warning signs, and are stretched at both ends by fixed stakes, fences, or other objects to form a physical isolation boundary.

[0003] Traditional safety barriers rely on visual warnings, which are limited in effectiveness. The color of the barrier itself and the printed text / graphics are passive visual warnings. In low light, cluttered environments, or with visual obstructions, safety barriers are easily overlooked and fail to effectively attract the attention of approaching individuals. Traditional safety barriers themselves lack sensing capabilities and cannot actively detect whether people or objects are approaching or attempting to cross them. Furthermore, when people approach the boundary, traditional safety barriers do not emit any active, immediate audible or visual warning signals to alert or prevent further approach.

[0004] There is an urgent need for a new type of warning device that retains the advantages of traditional warning lines—simple, easy to use, and flexibly deployable—while also being able to proactively detect approaching behavior and issue timely and effective warning information. This would overcome the aforementioned shortcomings of existing technologies and significantly improve the security, warning effect, and proactive defense capabilities of the warning area. Therefore, a warning line with voice broadcast is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a warning line with voice broadcast, which automatically senses the human body and issues a voice alarm. It can be widely used for protection and warning in the warning area, and solves the problem that traditional police equipment lines lack active warning functions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a warning tape with voice broadcast, including a warning tape with induction switches at both ends and the middle section of the warning tape. A voice broadcaster is arranged next to the induction switches, and three voice broadcasters are connected in parallel. A battery is installed at one end of the warning tape. Figure 2 As shown, there are three inductive switches. The three inductive switches are connected in parallel to each other, and then connected in series to the parallel circuit of the battery and the three voice broadcasters.

[0007] Preferably, the inductive switch is one or more combinations of a pressure sensor, a photoelectric sensor, or an infrared proximity sensor.

[0008] Preferably, the voice broadcaster and the corresponding sensor switch are encapsulated together in a waterproof housing, which is fixedly connected to the warning tape.

[0009] Preferably, an LED warning light is also provided next to the voice broadcaster, and the LED warning light is connected in series with the voice broadcaster.

[0010] Preferably, the battery is connected to a power management module, which includes a charging interface.

[0011] Preferably, the warning tape is a rollable strip structure with hooks at both ends for fixing, and the battery is placed in a roll box at one end of the warning tape.

[0012] Preferably, the warning line also includes a wireless communication module, which is electrically connected to the inductive switch.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model adds a voice prompt function in addition to physical isolation. When someone approaches, the voice prompt will play automatically, which will remind you in time and avoid noise pollution caused by frequent and uninterrupted broadcasts.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 As shown, a voice-announcing warning line includes a warning tape 1. The warning tape 1 provides physical isolation and serves as a basic structure. Once installed, it forms a visible physical boundary, clearly delineating the warning area. It has the advantages of traditional warning tape 1, such as simplicity, lightness, low cost, and ease of rapid deployment and storage. At the same time, it provides physical support and wiring channels for integrated electronic functions, such as internal circuit wiring, and provides basic visual warnings through color and printed text.

[0023] The warning strip 1 is equipped with induction switches 2 at both ends and in the middle. The induction switches 2 are responsible for detecting whether a person or object is approaching or touching the warning strip. When a target is detected, the switch state changes and sends a trigger signal to the subsequent circuit, which solves the problem of traditional warning strips being completely passive and can provide early warning of approaching behavior.

[0024] Three sensing points are set at both ends and the middle section of the warning strip 1 to cover key locations and reduce the risk of being ignored or crossed. Triggering any one of the sensing switches 2 will activate the alarm, preventing the entire line from failing due to the failure of a single point. A voice announcer 3 is installed next to each sensing switch 2, with three voice announcers connected in parallel. A battery 4 is installed at one end of the warning strip 1, providing power to all electronic components. The three sensing switches 2 are connected in parallel, and then connected in series with the battery 4 and the three voice announcers 3 in a parallel circuit.

[0025] When sensor switch 2 is triggered, voice announcer 3 plays a preset warning message, such as "Warning area, do not approach" or "Danger, entry prohibited," clearly informing approaching personnel of the nature of the area and the prohibition order, which is more effective than simple visual signs. The sound travels a long distance, is not limited by light, and effectively attracts attention, especially for those who are distracted or have poor eyesight. The announcement is made immediately after sensor triggering, providing real-time alerts, and only occurs when someone approaches, avoiding continuous noise pollution. The three announcers are distributed along the warning line, ensuring the sound is clearly audible near the approaching point and providing wider coverage. Any one announcer can be triggered to sound, and the simultaneous operation of all three results in a louder volume and better coverage. The failure of one announcer does not affect the operation of the others.

[0026] The specific design of the aforementioned key components will be discussed in detail below:

[0027] The inductive switch 2 is one or more combinations of a pressure sensor, a photoelectric sensor, or an infrared proximity sensor. A pressure sensor detects direct touch or stepping, has a relatively low false alarm rate, and is suitable for situations with clearly defined boundaries. Photoelectric or infrared sensors detect approaching behavior, providing earlier warnings and are suitable for situations requiring a greater safety distance; combining them can meet different needs.

[0028] The voice announcer 3 and its corresponding sensor switch 2 are encapsulated together within a waterproof housing 5, which is fixedly connected to the warning tape 1. The waterproof housing 5 protects the core electronic components from damage caused by rain, dust, splashes, and other environmental factors. This significantly enhances the reliability and lifespan of the equipment in harsh outdoor environments, such as rain, snow, sandstorms, and humidity, preventing functional failures due to moisture or dust ingress into components. The housing's fixation to the warning tape 1 provides additional mechanical protection.

[0029] An LED warning light is also installed next to the voice broadcaster 3, and the LED warning light is connected in series with the voice broadcaster 3. When the sensor switch 2 is triggered, the LED light lights up, providing a strong visual warning signal. Working in conjunction with the voice broadcast, it provides a dual-sensory warning, doubling the effect, especially important for visual warnings in noisy or nighttime environments. The LED light is conspicuous and has strong penetrating power, further enhancing the warning effect. The series design of the LED light and the voice broadcaster 3 working synchronously simplifies the control logic.

[0030] The battery 4 is connected to a power management module, which includes a charging interface. The power management module connects the battery 4 to the back-end circuitry and is responsible for the proper distribution, conversion, and protection of electrical energy. The battery 4 is charged via an integrated charging interface, such as USB-C or Micro USB. This charging interface allows users to easily recharge the device using a universal charger.

[0031] The warning tape 1 is a rollable, retractable strip structure with hooks at both ends for securing it. The battery 4 is housed in a roll case at one end of the warning tape 1. The roll case holds the rolled-up warning tape 1 for easy carrying and storage, and serves as a storage and protective container for the battery 4. The entire device is easy to roll up, store, and transport. The hooks at both ends of the warning tape 1 are used to quickly and easily attach the warning line to fixed objects such as railings, tree branches, posts, door and window handles, etc. This eliminates the need for complex installation tools and steps, enabling rapid deployment of the warning line and adapting to various fixing points in different environments. Note: Velcro can be attached to the edges of the warning tape 1; Velcro is another quick fixing method suitable for wrapping and securing.

[0032] The warning line also includes a wireless communication module 6, which is electrically connected to the induction switch 2. When the induction switch 2 is triggered, alarm information is sent to a remote monitoring center, management personnel's mobile phone, or intercom system via wireless signals such as Wi-Fi, Bluetooth, LoRa, NB-IoT, and GSM. This overcomes on-site limitations, allowing security personnel to be aware of the warning line's triggering status in real time, even if they are not nearby. Alarm events can be recorded for post-event analysis or auditing, making it particularly suitable for unattended or large-scale monitoring of important areas.

[0033] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
