Description

Technical Field

[0001] This utility model belongs to the field of vehicle-mounted safety monitoring equipment, and in particular relates to a vehicle-mounted environmental safety monitoring device. Background Technology

[0002] Port freight vehicles such as container trucks and forklifts are core to port operations, but their operational characteristics also make them a highly concentrated area of ​​safety hazards. These hazards not only threaten the lives of drivers and on-site staff but also seriously affect port operational efficiency and cargo safety. The main safety hazards can be categorized into vehicle-related hazards and those related to the operating environment. Heavy trucks, container trucks, and forklifts, due to their length and height, have numerous blind spots in all directions, especially directly in front, to the right, and close to the rear. These blind spots make them highly susceptible to collisions with pedestrians, other vehicles, or equipment during starting, turning, and reversing, and are a major cause of fatal accidents. The port area experiences dense traffic flow of vehicles, personnel (drivers, tally clerks, inspectors, etc.), and equipment (gantry cranes, forklifts), with intersecting traffic routes. Negligence by any party can lead to collisions or run-over accidents. In pursuit of efficiency, drivers may speed; prolonged, high-intensity work leads to driver fatigue and slowed reaction times. Speeding significantly increases the severity of accidents; fatigued driving is a major cause of vehicle loss of control and rear-end collisions. Therefore, it is very important to install environmental safety monitoring devices on port freight vehicles, especially trucks, lorries, and forklifts, to ensure the safety of drivers, passengers, and freight.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figure 1 As shown, the vehicle-mounted environmental safety monitoring device 10 consists of multiple modules, including a central control module 11 and a vision module 12, a locking module 13, an alarm module 14, and a pressure sensing module 15 that are communicatively connected to it. Taking a forklift transporting goods as an example, the central control module 11 acts as a central controller, located in the vehicle's central control system. It is communicatively connected to the vision module 12, the locking module 13, the alarm module 14, and the pressure sensing module 15, acquires and processes the information monitored by the vision module 12 and the pressure sensing module 15, and generates command signals to regulate the operation of the alarm module 14 and the locking module 13.

[0035] Two vision modules 12 are installed on the left and right sides of the vehicle. Each vision module 12 includes three cameras mounted on the A-pillar of the vehicle via mounting brackets 22, corresponding to the front, side, and driver positions of the vehicle, respectively. These cameras monitor obstacles in front of the vehicle, the driver's condition inside the vehicle, and obstacles on the sides, transmitting the monitoring information to the central control module 11. The central control module 11 analyzes the images to monitor pedestrian and vehicle traffic in front of and to the sides of the vehicle. It can also monitor the driver's working condition, whether there is fatigue driving, or emergency departure from the driver's seat. Compared with automotive radar solutions, the vision solution for vehicle safety has the advantages of lower cost and easier installation, but it requires higher ambient lighting. However, the lighting environment in application scenarios such as freight ports and warehouses is generally good and meets the requirements of the vision solution. In scenarios with good network environments, the vision solution also has the advantage of facilitating real-time access to on-site images by big data monitoring and control centers, aligning with the future development direction of smart ports and smart transportation.

[0036] In this embodiment, there are two vision modules 12, located on the A-pillars 21 on both sides of the front of the vehicle. Each vision module 12 has a forward-facing camera 23 for monitoring obstacles in front of the vehicle, such as pedestrians and vehicles, and the central control module 11 analyzes the distance and potential collision. A side camera 25 monitors pedestrians and vehicles approaching from the side, and the central control module 11 also analyzes the distance and potential collision. When the central control module determines whether the surrounding environment is dangerous based on the analysis results, it controls the locking module 13 to activate the door locking and seatbelt unlocking as a warning. If the vision module 12 detects a dangerous signal indicating that a vehicle or pedestrian is too close in front of or to the side of the vehicle, there are typically two hazard handling methods depending on the vehicle's current state.

[0037] (1) When the vehicle is in motion: the central control module 11 sends a control signal to the alarm module 14 to remind the driver to brake in an emergency to avoid a collision.

[0038] (2) When the vehicle is stationary: It is not advisable to open the door in this situation, as it may cause collision damage to pedestrians or vehicles, or injury to the driver during the opening process. In this state, the central control module 11 issues a command, which, through the locking module 13, prevents the driver from leaving the seat or opening the door, thus preventing injury to themselves or pedestrians. The locking module 13 locks the seatbelt buckle, and if it is forcibly opened, the driver will be alerted through the in-vehicle broadcast system of the alarm module 14.

[0039] The alarm module 14 is typically a loudspeaker, located in the vehicle's in-vehicle broadcast system and external horn, to alert the driver and surrounding vehicles. For example, in a freight vehicle, the alarm module 14 functions as a buzzer inside the vehicle and an electric horn outside, both controlled by the central control module 11. When the vision module 12 senses that someone is passing by and it is inappropriate to open the door, both the buzzer and the electric horn sound simultaneously. For safety risks to the driver, the central control module 11 will control the in-vehicle broadcast system and buzzer to sound an alarm, preventing the driver from unfastening their seatbelt in dangerous situations. For potential collision risks to pedestrians on the roadside, the central control module 11 will control the external electric horn to sound an alarm, alerting pedestrians to the vehicle. Simultaneously, it will also lock the doors controlled by the locking module 13, preventing the driver from opening the doors.

[0040] Pressure sensing modules 15 are installed in the seat cushions and backrests of each seat in the vehicle. They can detect whether the driver is driving normally and whether there is any tendency to leave the driver's seat based on sensor data, so that the central control module 11 can comprehensively analyze the driver's real-time status. Working in conjunction with the vision module 12, it also has the function of monitoring and alarming for dangerous behaviors such as driver inattention and drowsiness.

[0041] For applications requiring high safety, such as those where there are no obstacles in front of the vehicle, the vision module 12 can also be equipped with only two cameras: a side camera 25 and a driver camera 26.

[0042] Equipment installation status: The hardware of vision module 12 is mainly composed of mounting bracket 22, such as... Figure 2 and 3 As shown, the mounting bracket 22 is shaped to match the A-pillar 21 of the vehicle to which it is installed, and is fixedly connected. It is preferably installed on the outer side of the A-pillar 21 of the vehicle, and can be bolted or welded to the A-pillar 21 of the vehicle as needed. For extra-long or extra-wide vehicles, the mounting bracket 22 can also be added in the parking space or other places with greater safety risks to form a set of vehicle environmental safety monitoring devices 10.

[0043] To accurately connect the mounting bracket 22 to the vehicle's A-pillar 21, a positioning pin groove 32 is formed on the outer side of the A-pillar 21, and a side positioning groove 31 is formed laterally on the front side. The side positioning groove 31 extends out of the outer side of the A-pillar 21. A positioning pin 34 is set in the corresponding positioning pin groove 32 on the inner side of the mounting bracket 22, and a side positioning block 33 is set in the corresponding side positioning groove 31. The side positioning block 33 protrudes above the positioning pin 34. The side positioning block 33 and the side positioning groove 31 are assembled, and the positioning pin 34 and the positioning pin groove 32 are assembled. For temporary installation scenarios such as in ports, where on-site installers are often not professionally trained, a simple positioning and matching setup allows on-site personnel to easily master the installation techniques. During installation, simply aligning the corresponding grooves and positioning protrusions allows for quick and accurate positioning, followed by bolting or welding using conventional tools.

[0044] The positioning pin slots 32 and positioning pins 34 are in two sets, with different diameters corresponding one-to-one. As shown in the figure, the diameter of the upper positioning pin 34 is significantly larger than that of the lower positioning pin 34. This ensures that inexperienced installers will not make mistakes. If the installation position is incorrect, the different hole diameters will prevent proper locking and positioning. In this case, the operator can easily detect the installation error, readjust the installation position, and avoid incorrect installation.

[0045] For applications with high usage intensity and significant camera wear, to facilitate rapid camera replacement, a camera mounting base 201 can be equipped with a camera clip 202, such as... Figure 4 As shown, the camera mounting bracket 202 is welded to the mounting bracket 22, serving as a quick-release base. It has a groove inside for the camera base 201 to be snapped into place, and the groove wall is coated with a soft rubber-like material to facilitate the snapping of the camera base 201.

[0046] The vision module 12 can also connect to a real-time monitoring network via the signal transmitter 24 to synchronize audio and video information to the transportation management center in real time, facilitating remote monitoring and management.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
