Description

Technical Field

[0001] This utility model relates to the field of laser intrusion detector technology, and more specifically to a dual-source laser intrusion detector with voice function. Background Technology

[0002] A laser intrusion detector is an active intrusion detector that uses a laser as its light source. Laser intrusion detectors are generally used on the perimeter of various key security areas as high-performance detectors to prevent unauthorized intrusion. To improve the concealment of the intrusion detector, most laser intrusion detectors use invisible lasers as their light source. However, when using invisible lasers as the light source, aligning the laser beams of the laser transmitter and receiver has always been a headache for users. Currently, the method for adjusting the laser transmitter and receiver of laser intrusion detectors using invisible lasers on the market is as follows: The user moves a handheld audible and visual locator between the laser transmitter and receiver to search for the invisible laser signal. When the locator detects the invisible laser signal, it emits an audible and visual alert. Based on the audible and visual alert, the user can confirm the current position of the invisible laser beam and then adjust the laser beam direction by adjusting the vertical / horizontal angle to point it towards the corresponding receiver window of the laser receiver. This method of searching for laser signals bit by bit using a handheld audio-visual locator is extremely inefficient and makes it difficult to achieve precise alignment between the laser transmitter and receiver beams, causing significant inconvenience and confusion for laser intrusion detector users. On the other hand, while the number of auxiliary functions in laser intrusion detectors on the market is increasing, none offer a user-friendly, intuitive, and efficient operating interface. Currently, auxiliary function selection in laser intrusion detectors relies on function buttons, with different beeps or LCD codes indicating the current operation option. This method requires users to carefully listen to the beeps and interpret the LCD codes, making it complex and prone to errors, thus undermining user confidence in using the laser intrusion detector.

[0003] The current problems with existing laser intrusion detectors on the market have significantly hindered their widespread adoption, making it difficult for users to decide whether to use them. Therefore, designing a laser intrusion detector with a user-friendly interface, simple operation, and precise and efficient light adjustment is a pressing challenge for the laser intrusion detector industry. Utility Model Content

[0004] In view of this, the present invention provides a dual-source laser intrusion detector with voice broadcast function that is simple to operate, intuitive, and has precise and efficient light adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-source laser intrusion detector with voice function, characterized in that the laser intrusion detector includes a laser transmitter and a laser receiver used in conjunction with the laser transmitter; wherein the laser transmitter is provided with a dual-source laser transmitter, a laser modulation and beam encryption microprocessor, a first voice chip, a first power amplifier circuit, a first speaker, a first power supply circuit, and a first rotary encoder; the laser receiver is provided with a laser receiver, a signal demodulation and identification microprocessor, an alarm signal processing and output control microprocessor, a second voice chip, a second power amplifier circuit, a second speaker, a second power supply circuit, and a second rotary encoder.

[0007] Preferably, in the above-mentioned dual-source laser intrusion detector with voice function, the laser transmitter has two working modes: detection and debugging. The user can switch between the two working modes by operating the first rotary encoder of the laser transmitter.

[0008] Preferably, in the aforementioned dual-source laser intrusion detector with voice function, each set of dual-source laser emitters within the laser transmitter includes a visible light laser and an invisible light laser; the visible light laser and the invisible laser on each set of dual-source laser emitters have overlapping laser beam focal points; the visible light laser operates in the laser transmitter's debugging mode, and the invisible laser operates in the laser transmitter's detection mode; in debugging mode, the user can sequentially illuminate the visible light laser of each beam by operating the first rotary encoder; when the visible light laser is operating, the precise alignment of each visible light laser beam of the laser transmitter with each receiving window of the laser receiver is achieved by adjusting the dual-source laser beam angle adjustment mechanism; each time the user switches modes or performs function operations through the first rotary encoder, the voice circuit of the laser transmitter will play the voice corresponding to the operation content.

[0009] Preferably, in the above-mentioned dual-source laser intrusion detector with voice function, the laser receiver has multiple auxiliary functions available. The user can switch between auxiliary functions by operating the second rotary encoder of the laser receiver. Each time the user performs an auxiliary function switch operation through the second rotary encoder, the voice circuit of the laser receiver will play the voice corresponding to the operation content.

[0010] Preferably, in the above-mentioned dual-source laser intrusion detector with voice function, the first power amplifier circuit and the second power amplifier circuit inside the laser transmitter and the laser receiver are included inside the voice chip.

[0011] Preferably, in the above-mentioned dual-source laser intrusion detector with voice function, the laser transmitter and laser receiver are paired devices, and in the same pair of detectors, the number of laser beams of the laser transmitter and laser receiver is the same.

[0012] Preferably, in the above-mentioned dual-source laser intrusion detector with voice function, the laser transmitter and laser receiver are installed face-to-face in two housings to form a pair to form a through-beam laser intrusion detector, or the laser transmitter and laser receiver are installed in the same housing and a reflector is used to form a reflective laser intrusion detector.

[0013] As can be seen from the above technical solution, compared with the prior art, this utility model improves the traditional laser intrusion detector's single invisible light source laser emitter into a dual-source laser emitter with both visible and invisible light. At the same time, it adds voice circuits to the laser transmitter and laser receiver, so that each step of the laser transmitter and laser receiver's operation is accompanied by voice prompts. When the laser transmitter and laser receiver are aligned and debugged, they are guided by the visible light laser, thereby achieving fast and efficient completion of laser transmitter beam alignment and function settings. This solves the problems of low light debugging efficiency and complex function operation of traditional laser intrusion detectors, and has the technical characteristics of being easy to understand, intuitive, simple and efficient.

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.

[0019] This utility model discloses a dual-source laser intrusion detector with voice function.

[0020] Please see the appendix Figure 1 The present invention discloses a dual-source laser intrusion detector with voice function, specifically comprising:

[0021] A laser transmitter 1 and a laser receiver 2 used in conjunction with the laser transmitter 1; wherein the laser transmitter 1 is provided with a dual-source laser transmitter 3, a laser modulation and beam encryption microprocessor 4, a first voice chip 5, a first power amplifier circuit 6, a first speaker 7, a first power supply circuit 8, and a first rotary encoder 9; the laser receiver 2 is provided with a laser receiver 10, a signal demodulation and identification microprocessor 11, an alarm signal processing and output control microprocessor 12, a second voice chip 13, a second power amplifier circuit 14, a second speaker 15, a second power supply circuit 16, and a second rotary encoder 17.

[0022] To further optimize the above technical solution, in the above-mentioned dual-source laser intrusion detector with voice function, the laser transmitter has two working modes: detection and debugging. Users can switch between the two working modes by operating the rotary encoder of the laser transmitter.

[0023] To further optimize the above technical solution, in the aforementioned dual-source laser intrusion detector with voice function, each set of dual-source laser emitters within the laser transmitter includes one visible light laser and one invisible light laser; the visible light laser and the invisible laser on each set of dual-source laser emitters have overlapping laser beam focal points; the visible light laser operates in the laser transmitter's debugging mode, and the invisible laser operates in the laser transmitter's detection mode; in debugging mode, the user can sequentially illuminate the visible light laser of each beam by operating the rotary encoder, and adjust the beam angle of the dual-source laser to... The entire mechanism ensures precise alignment between each visible laser beam from the laser transmitter and each receiving window of the laser receiver. Since the focal points of the visible and invisible laser beams of each dual-source laser overlap, when the visible laser beam from the laser transmitter is precisely aligned with the corresponding receiving window of the laser receiver, it indicates that the invisible laser beam from the same dual-source laser has also been precisely aligned with the corresponding receiving window of the laser receiver. Each time the user switches modes or performs function operations via the rotary encoder, the voice circuit of the laser transmitter will play the corresponding voice prompt.

[0024] To further optimize the above technical solution, in the aforementioned dual-source laser intrusion detector with voice function, the laser receiver has multiple auxiliary functions available. Users can switch between auxiliary functions by operating the rotary encoder of the laser receiver. Each time the user performs an auxiliary function switch operation through the rotary encoder, the voice circuit of the laser receiver will play the voice corresponding to the operation content.

[0025] To further optimize the above technical solution, in the above-mentioned dual-source laser intrusion detector with voice function, the first power amplifier circuit and the second power amplifier circuit inside the laser transmitter and the laser receiver are included inside the voice chip.

[0026] To further optimize the above technical solution, in the aforementioned dual-source laser intrusion detector with voice function, the laser transmitter and laser receiver are paired devices, and in the same pair of detectors, the number of laser beams of the laser transmitter and laser receiver is the same.

[0027] To further optimize the above technical solution, in the aforementioned dual-source laser intrusion detector with voice function, the laser transmitter and laser receiver are installed face-to-face in two housings to form a pair to form a through-beam laser intrusion detector, or the laser transmitter and laser receiver are installed in the same housing and a reflector is used to form a reflective laser intrusion detector.

[0028] After purchasing a laser intrusion detector and installing it at the site, users must first perform beam alignment adjustments and configure the detection and alarm functions of the laser transmitter and receiver to ensure the laser intrusion detector is in normal working order and meets the application requirements of the installation site. Under normal power-on conditions, users first need to perform alignment adjustments on each beam of the laser transmitter and receiver. At the laser transmitter end, the user simply presses the rotary encoder for 3 seconds, and the laser transmitter will issue a voice prompt "Enter debugging mode." At this time, the visible light laser in the first dual-source laser of the laser transmitter emits visible laser light. Since the visible light and invisible light lasers in each dual-source laser of the laser transmitter are pre-calibrated to a state of focal overlap at the factory, the user can determine the beam direction of the invisible laser that overlaps with its focal point based on the direction of the visible light laser beam. If the beam direction of the visible light laser in the first dual-source laser is not precisely aligned with the first receiving window of the laser receiver, the user can adjust the vertical and horizontal angles of the first dual-source laser of the laser transmitter until the visible light laser beam in the first dual-source laser of the laser transmitter is precisely aligned with the first receiving window of the laser receiver. Then, the user rotates the rotary encoder of the laser transmitter, and the laser transmitter enters debugging mode. In the second dual-source laser debugging mode, the laser transmitter emits a voice prompt saying "Second beam debugging." The visible light laser within the second dual-source laser emits visible laser light. The user can adjust the angle up / down and left / right based on the beam direction of the visible light laser in the second dual-source laser until the visible light laser beam from the laser transmitter is precisely aligned with the second beam receiving window of the laser receiver. Next, the user rotates the rotary encoder of the laser transmitter to perform the third beam alignment debugging. Repeat the above operations until all beams are precisely aligned. Since the focal points of the visible and invisible laser beams of each dual-source laser overlap, when the visible light laser beam from the laser transmitter is precisely aligned with the corresponding receiving window of the laser receiver, it indicates that the invisible laser beam from the same dual-source laser has also been precisely aligned with the corresponding receiving window of the laser receiver. At the laser receiver end, users can enter the function setting state by pressing the rotary encoder of the laser receiver for three seconds. The laser receiver will then issue a voice prompt saying "Enter settings." Users can then rotate the rotary encoder to switch function settings, such as "trigger mode," "response time," and "beam shielding selection." Each time the user operates the rotary encoder, the laser receiver will automatically broadcast the corresponding operation command pre-set in the voice module, allowing users to easily understand each step of the operation through voice and know what to do next. This simple and efficient way of setting up various functions meets the different application needs of laser intrusion detectors in different locations.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
