Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance operations, and specifically relates to a highway pavement operation safety warning system based on the Internet of Things. Background Technique

[0002] With the continuous expansion of China's highway network, the traffic volume has been increasing day by day, which has brought severe safety challenges to highway maintenance operations. Maintenance units not only have to ensure smooth traffic, but also face huge safety risks and management problems.

[0003] Many traffic accidents are caused by vehicles breaking into the construction operation area. Since the vehicle speed on highways is relatively fast, daily maintenance operations often require closing some lanes, resulting in changes in the traffic environment, and the vehicle speed and distance also change violently. If the on-site defense is improper, coupled with individual drivers speeding or being inattentive, it is very likely that the vehicle will lose control and rush into the operation area, causing casualties to the operating personnel and even triggering major accidents with multiple deaths and injuries. Content of the Utility Model

[0004] The purpose of the utility model is to provide a highway pavement operation safety warning system based on the Internet of Things, which can measure the speed of vehicles approaching the pavement for maintenance on the highway. When there are speeding vehicles, it can remind the relevant construction operation personnel, enabling the relevant construction operation personnel to make safety precautions in advance.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a highway pavement operation safety warning system based on the Internet of Things, which is characterized in that: it includes a speed limit sign component arranged in front of the highway pavement operation area and a smart bracelet worn on the hands of relevant construction personnel; the speed limit sign component includes a speed limit signboard with a speed limit sticker, and a radar speed detector, a speed display screen, a single-chip microcomputer controller and a rechargeable battery are installed on the speed limit signboard. The radar speed detector and the speed display screen are respectively connected to the single-chip microcomputer controller; the single-chip microcomputer controller is connected to the smart bracelet through a wireless communication module; the radar speed detector monitors the speed of passing vehicles and displays it on the speed display screen. When the speed of the passing vehicle exceeds the speed marked on the speed limit sticker, the single-chip microcomputer controller sends a control signal for vibration to the smart bracelet through the wireless communication module, and the smart bracelet vibrates and alarms after receiving the control signal.

[0006] Further, a flash lamp is also installed on the speed limit signboard. When the speed of the passing vehicle exceeds the speed marked on the speed limit sticker, it flashes at the vehicle to remind the driver that they are speeding.

[0007] Further, the wireless communication module is a wifi module or a bluetooth module.

[0008] Further, a base is connected to the lower end of the support rod of the speed limit sign board.

[0009] The beneficial effects of the present utility model are as follows: By setting a speed limit sign assembly in front of the road surface near highway maintenance operations, the radar speedometer monitors the speeds of passing vehicles to determine whether the speeds of the vehicles traveling in this area exceed the limited speed. If the limited speed is exceeded, a control signal is sent to the smart bracelet to remind the relevant construction personnel that there are speeding vehicles approaching the operation area, and they need to pay attention to safety and take safety precautions.

[0010] In addition, a flash lamp is also provided on the speed limit sign board. When the speed of a passing vehicle exceeds the speed indicated on the speed limit sticker, it can flash at the vehicle to remind the driver that they are speeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic structural diagram of the present utility model;

[0012] Figure 2 is a schematic diagram of the installation position of the speed limit sign assembly when the present utility model is applied. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0014] As Figure 1 shown, a highway pavement operation safety warning system based on the Internet of Things of the present invention includes a speed limit sign assembly 100 arranged in front of the highway pavement operation area and a smart bracelet 200 worn on the hands of relevant on-site construction personnel. In actual application, the number of smart bracelets 200 is configured according to the actual number of on-site operators.

[0015] The speed limit sign assembly 100 includes a speed limit sign board 102 with a speed limit sticker 101. The speed limit sticker 101 is an adsorptive sticker with a speed limit value. The values on the adsorptive sticker are 60, 80, etc. When applying, a speed limit sticker 101 with a suitable value is selected according to the actual situation and pasted on the speed limit sign board 102.

[0016] On the speed limit sign 102, a radar speed detector 103, a speed display screen 104, a single-chip microcomputer controller and a rechargeable battery are also installed. Among them, the radar speed detector 103 and the speed display screen 104 are respectively connected to the single-chip microcomputer controller; the single-chip microcomputer controller is connected to the smart bracelet 200 through a wifi module or a Bluetooth module. The radar speed detector 103 monitors the speed of passing vehicles, and the speed display screen 104 displays the speed of the monitored passing vehicles. When the speed of a passing vehicle exceeds the speed marked on the speed limit sticker, the single-chip microcomputer controller sends a vibration control signal to the smart bracelet 200 through a wireless communication module. After receiving the control signal, the smart bracelet 200 vibrates to give an alarm. In this way, the smart bracelet 200 can vibrate to remind the operator that a speeding vehicle has entered the work section and pay attention to safety.

[0017] Preferably, a flash lamp 105 is also installed on the speed limit sign 102. When the speed of a passing vehicle exceeds the speed marked on the speed limit sticker, the flash lamp 105 lights up and flashes at the vehicle to remind the driver that they are speeding. In this way, through the flashing reminder of the flash lamp, a driver with inattentive attention can be alerted and reduce the vehicle speed to within the speed limit range to pass through the work area safely.

[0018] Further, a base is connected to the lower end of the support rod of the speed limit sign. Due to the temporary nature of the construction work, the general working time is not too long. By setting a load-bearing base, the stability of the speed limit sign can be increased, it is convenient to place, and the position can be moved at any time.

[0019] In addition, the above rechargeable battery powers the radar speed detector 103, the speed display screen 104, the flash lamp 105, and the controller. When it runs out of power, the battery can be replaced or charged through a charger.

[0020] Further, the radar speed detector is also provided with a load-bearing base to increase stability and can move the working position at any time.

[0021] Specifically, such as Figure 2As shown in the figure, when carrying out construction operations on the highway with an original speed limit of 100 km / h, various signs and enclosures are set up along the highway as required, and a speed limit sign assembly of the present utility model is additionally provided at position A in front of the construction area. The specific work process is as follows: When a vehicle enters position A, the speed is monitored by a radar speed detector, and the vehicle speed is compared with the speed on the speed limit sticker. When it is judged that the vehicle speed is below the limit speed, no control operation is required, and passing vehicles are continuously monitored. When it is judged that the vehicle speed of a vehicle passing through position A exceeds the limit speed, the flash lamp at position A flashes at the vehicle to remind the driver to pay attention. At the same time, the controller issues a control signal to control the intelligent bracelet to vibrate continuously for a period of time, reminding the construction-related personnel that there is an overspeed vehicle entering the adjacent operation area and they need to pay attention to safety. Among them, the continuous vibration time of the intelligent bracelet can be set according to actual needs, such as 5 seconds, etc.

[0022] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents; all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
