Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment, and more specifically, to a personnel on-duty status monitoring system based on UWB radar. Background Technology

[0002] In industries such as manufacturing, chemicals, metallurgy, power, transportation, water conservancy, mining, and energy, especially for personnel on duty in important positions, it is inevitable that they will leave their posts or sleep on duty. Therefore, it is particularly important to effectively supervise the behavior of personnel on duty and to promptly detect any violations.

[0003] Regarding the management of the on-duty status and behavior of key personnel in enterprises, the following methods are currently mainly adopted by enterprises to deal with the situation;

[0004] 1. Manual Inspection: This involves assigning dedicated personnel to regularly inspect duty posts, observing staff to determine their presence and work status. This method is inefficient, requiring significant manpower and time. The inspection cycle is long, and it cannot promptly detect staff leaving their posts or sleeping on duty.

[0005] 2. Video Surveillance: This method involves installing cameras to monitor duty posts in real time. Management personnel can review the video feed from the control room to assess the staff's status. However, this solution requires staff to continuously monitor the screen, which can lead to fatigue. It also lacks automatic monitoring and alarm functions, placing high demands on management personnel.

[0006] 3. Machine Vision Behavior Recognition: This method collects image or video data through cameras and then uses artificial intelligence algorithms to analyze and judge the behavior of people in the images. This solution is highly dependent on the on-site environment, has low accuracy in recognizing human behavior, is prone to misjudging human behavior, has high system deployment and implementation costs, and may infringe on the privacy of on-duty personnel.

[0007] 4. Radar video monitoring: such as the critical personnel departure warning device with announcement number CN210243834U, which monitors by combining radar and video. It focuses on warning, but it is inconvenient for personnel supervision. It is difficult for supervisors to understand the site in a timely and clear manner. In addition, it does not involve specific structures and has poor adaptability to different installation occasions. Utility Model Content

[0008] The purpose of this invention is to provide a personnel on-duty status monitoring system based on UWB radar. The system can change the horizontal position of the UWB radar through the mounting slot and radar mounting rod, and can change the angle of the UWB radar through the ball head structure, thereby achieving the optimal angle. The monitoring device is connected to a mobile terminal, which makes it convenient for supervisors to monitor the on-site situation and supervise the work in real time.

[0009] This utility model is achieved through the following technical solution:

[0010] A UWB radar-based personnel on-duty status monitoring system includes several monitoring devices. Each monitoring device includes a housing, which is mounted on a wall via a mounting bracket. The housing has a mounting groove, in which a radar mounting rod is slidably mounted. The radar mounting rod is fitted with a UWB radar via a ball joint structure. A camera is located at the bottom of the housing, and a speaker and microphone are also located on the housing above the camera. All monitoring devices are connected to a switch, which is connected to a control host, which is connected to a mobile terminal.

[0011] Furthermore, the ball joint structure includes an outer ball joint on the radar mounting rod and an inner ball joint on the UWB radar mounting frame, with frictional resistance between the outer ball joint and the inner ball joint.

[0012] Furthermore, the mounting groove is a T-shaped mounting groove, and the mounting part of the radar mounting rod mates with the T-shaped mounting groove.

[0013] Furthermore, it also includes a control motherboard located inside the housing. The control motherboard is connected to the UWB radar, camera, audio module and power module respectively. The speaker and microphone are connected to the control motherboard through the audio module. The control motherboard is also connected to a storage hard drive. The power module supplies power to the entire device.

[0014] Furthermore, each of the aforementioned monitoring devices is connected to the switch via the TCP / IP protocol.

[0015] Furthermore, the control host is connected to a mobile terminal via a 4G network, allowing supervisors to monitor the system at any time.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The horizontal position of the UWB radar can be changed by the mounting slot and radar mounting rod, and the angle of the UWB radar can be changed by the ball head structure, so as to achieve the optimal angle and better adapt to the installation requirements of various spaces. Even if the layout of the monitoring area changes later, there is no need to reinstall the equipment.

[0018] 2. The monitoring device is connected to a mobile terminal, which makes it convenient for supervisors to monitor the situation on site and carry out supervision in real time.

[0019] 3. The camera can take photos and videos to record abnormal situations, making it easy to trace back.

[0020] 4. Highly efficient and accurate, reducing operation and monitoring costs; highly adaptable; relatively simple device structure; easy to install. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figures 1-2 As shown, a UWB radar-based personnel on-duty status monitoring system includes several monitoring devices. Each monitoring device includes a housing 1, which is mounted on a wall via a mounting bracket 8. The housing 1 has a mounting groove 2, within which a radar mounting rod 3 slides. A UWB radar 4 is mounted on the radar mounting rod 3 via a ball joint structure 5. The radar mounting rod 3 can slide within the mounting groove 2 to change the horizontal position of the UWB radar 4. A spherical camera 7 is located at the bottom of the housing 1, and a speaker 6 and a microphone 9 are also located on the housing 1 above the camera 7. All monitoring devices are connected to a switch, which is connected to a control host, which is connected to a mobile terminal. The UWB radar 4 emits non-sinusoidal narrow pulse signals in the nanosecond to picosecond range and receives signals reflected from personnel. These signals carry information about chest rise and fall and heartbeat, allowing real-time monitoring of personnel status and transmitting relevant data to other modules for processing. The specific principles are existing technology and will not be elaborated upon.

[0028] Example 2

[0029] like Figure 3As shown, a personnel on-duty status monitoring system based on UWB radar is disclosed. The ball joint structure includes an outer ball joint mounted on the radar mounting rod 3 and an inner ball joint mounted on the UWB radar 4 mounting bracket, with a certain frictional resistance between the outer and inner ball joints. The mounting groove 2 is a T-shaped mounting groove, and the mounting part of the radar mounting rod 3 mates with the T-shaped mounting groove. It also includes a control mainboard housed within the housing 1, which is connected to the UWB radar 4, camera 7, audio module, and power module. A speaker 6 and microphone 9 are connected to the control mainboard via the audio module. The control mainboard is also connected to a storage hard drive, and the power module supplies power to the entire device. Each monitoring device is connected to a switch via TCP / IP protocol. The control host is connected to a mobile terminal via a 4G network, allowing supervisors to monitor the system at any time. Other aspects are the same as in Embodiment 1. The camera 7 supports pan-tilt rotation to achieve video monitoring functionality, taking photos as evidence when abnormal situations are detected. The audio module and power module are existing technologies.

[0030] The UWB radar 4's ball-head structure allows for adjustable installation angles, better adapting to various spatial installation requirements. Even if the layout of the monitored area changes later, there's no need to reinstall the equipment; simply adjust the angle of the UWB radar 4.

[0031] When personnel are found sleeping on duty or absent from their posts, the UWB radar 4 detects the abnormal status and will sound an alarm through the speaker 6. It will also remotely alert relevant supervisory personnel via a mobile terminal, allowing them to view live footage from the camera 7. Furthermore, the storage hard drive will promptly store the video footage of the anomaly for easy review at any time. Supervisory personnel can also communicate with on-duty staff via their mobile terminals, with on-duty staff using microphones to communicate with supervisory personnel.
