[0009] In a preferred embodiment, the top of the support column is provided with a threaded hole;

[0010] The support platform plate has a circular groove in the middle, and a circular hole in the center of the circular groove.

[0011] The movable seat includes a fixed plate, the fixed plate being the same size as the circular groove. A rotating seat is movably provided on the top surface of the fixed plate, and a threaded post is provided at the bottom of the fixed plate.

[0016] The safety production voice alarm device provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0017] (1) By setting up a sensor module containing an RFID reader, the RFID tags worn by personnel entering the maintenance area can be read in real time and accurately, thereby accurately counting the number of personnel. In conjunction with the control module, the total number of personnel in the area can be effectively controlled. When the number of personnel reaches the preset threshold, an early warning will be triggered in time, greatly reducing the risk of safety accidents caused by personnel exceeding the limit.

[0028] A support platform plate 6 is provided above the support column 5, and a rotatable movable seat 7 is provided on the support platform plate 6. A monitoring mechanism 8 is provided on the top of the movable seat 7.

[0029] In a preferred embodiment, the monitoring mechanism 8 includes a camera 11 and a sensor module 14. Both the camera 11 and the sensor module 14 are connected to the control module, and the control module is remotely wirelessly connected to the remote monitoring screen via a LoRa communication module.

[0030] In a preferred embodiment, the sensor module 14 includes an infrared human body sensor and an RFID reader, the RFID reader being used to read the RFID tags worn by the person.

[0031] In a preferred embodiment, a limiting key 502 is provided on the outer wall of the support column 5. The support column 5 extends into the guide cylinder 4, and the radial positioning of the support column 5 is achieved through the cooperation of the slot on the inner wall of the guide cylinder 4 and the limiting key 502.

[0032] In a preferred embodiment, the support column 5 is provided with a threaded hole 501 at its top;

[0033] The support platform plate 6 has a circular groove 601 in the middle, and a circular hole 602 is provided in the center of the circular groove 601.

[0034] The movable seat 7 includes a fixed plate 701, the fixed plate 701 being the same size as the circular groove 601, a rotating seat 702 being movably provided on the top surface of the fixed plate 701, and a threaded post 703 being provided at the bottom of the fixed plate 701, the threaded post 703 passing downward through the circular hole 602 and being fixed in the threaded hole 501 by threads.

[0035] In a preferred embodiment, a first motor 10 is provided on the fixed plate 701, and an annular groove 704 is provided on the outer wall of the rotating seat 702. The drive shaft of the first motor 10 is connected to the annular groove 704 by a transmission belt.

[0036] In a preferred embodiment, the main body of the monitoring mechanism 8 is a plate structure with an ear seat 13. The camera 11 is movably mounted on the ear seat 13. A pin on one side of the ear seat 13 extends out of the ear seat 13. The monitoring mechanism 8 is also equipped with a second motor 12. The drive shaft of the second motor 12 is connected to one end of the pin extending out of the ear seat 13 via a transmission belt.

[0037] In a preferred embodiment, the top surface of the rotating base 702 is provided with a grooved mounting hole 705, and the bottom of the monitoring mechanism 8 is provided with a connecting post 801 with a protruding key, the connecting post 801 being inserted into the mounting hole 705.

[0038] In a preferred embodiment, the base 1 is equipped with a voice playback device 9, and the control module is connected to the voice playback device 9.

[0039] The present invention discloses a safety production voice alarm device, taking its use in a large generator maintenance workshop as an example:

[0040] The base plate 1 is securely installed on the designated monitoring area floor of the maintenance workshop, and the push cylinder 2 and bracket 3 are then fixed in place. Based on the actual maintenance work space and monitoring requirements, the push cylinder 2 is activated, and its push rod 201 extends upwards from the bottom of the guide cylinder 4, pushing the support column 5 to move vertically within the guide cylinder 4. Because the limiting key 502 on the outer wall of the support column 5 cooperates with the slot on the inner wall of the guide cylinder 4, radial displacement is effectively prevented during the movement of the support column 5, precisely and stably adjusting the support platform plate 6 and the monitoring mechanism 8 installed on it to the appropriate height.

[0041] Regarding personnel management, maintenance personnel wear RFID tags containing unique identification information before entering the work area. The RFID reader (using an RS485 non-contact RFID reader) in sensor module 14 operates continuously, scanning the RFID tags worn by personnel entering the maintenance area in real time and transmitting the read personnel information to the control module. The control module performs statistical analysis on the personnel information. When the number of personnel entering the area reaches a preset threshold, such as 50 people, the control module immediately triggers the voice playback device 9 on base 1 to issue a voice warning to the site stating "The number of personnel has reached the limit, please postpone entry." At the same time, the personnel exceeding the limit information is simultaneously sent to the remote monitoring screen via the LoRa communication module, allowing management personnel to promptly grasp the on-site situation and take appropriate measures.

[0042] An infrared human body sensor (using an HC-SR505 pyroelectric infrared sensor) works in conjunction with camera 11 to achieve comprehensive monitoring of personnel activities. The infrared human body sensor constantly senses the dynamic activities of people in the area. Once abnormal behavior is detected, such as prolonged stillness or rapid running, a signal is immediately transmitted to the control module. The control module then controls camera 11 to focus and capture images, and transmits the scene to a remote monitoring screen in real time via the LoRa communication module. At the same time, the control module will also issue targeted warning voices through the voice playback device 9 according to a preset program, such as "Please maintain normal working speed to avoid accidents."

[0043] To adjust the monitoring angle, the first motor 10 on the fixed plate 701 can be activated. The drive shaft of the first motor 10 drives the annular groove 704 on the outer wall of the rotating seat 702 to rotate via a transmission belt, thereby rotating the movable seat 7 and causing the monitoring mechanism 8 to adjust its horizontal angle, thus expanding the monitoring range. To adjust the pitch angle of the camera 11, the second motor 12 on the monitoring mechanism 8 can be activated. The drive shaft of the second motor 12 drives the pin protruding from the ear seat 13 to rotate via a transmission belt, thereby changing the vertical angle of the camera 11 to meet the precise monitoring needs in different scenarios.
