Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
In a common road maintenance work scene, a road maintenance worker performs a head burying work in a work area, and a vehicle traveling at a high speed is outside the work area. At present, no effective and high-cost-performance early warning system is available in the market for early warning of road maintenance operators, and all security measures are taken by drivers to avoid traffic safety and dispose warning obstacles such as water horses or conical barrels around an operation area. Therefore, once a vehicle running at a high speed breaks into the operation area, the road maintenance operator is very easy to cause traffic accidents because the vehicle cannot avoid the traffic accidents in time.
In order to solve the above deficiency of the prior art, the embodiment provides a traffic accident early warning system for road maintenance operation, can send out the safe warning suggestion when warning obstacles such as the water horse or the cone-shaped barrel of vehicle collision operation region periphery to remind road maintenance operation personnel to make safeguard measure at once, win more time of fleing for road maintenance operation personnel, thereby ensure road surface constructor's operation security.
As shown in fig. 2, the traffic accident warning system applied to road maintenance operation of the present embodiment includes: at least one traffic accident detection device 1 applied to road maintenance work, and an alarm device 2.
As will be described in detail below.
Specifically, as shown in fig. 3, the road maintenance worker places obstacles such as conical barrels and water horses on the road according to the safety standard, closes the road in advance within a specified distance, and performs construction work within a construction range surrounded by a plurality of conical barrels. After the staff deploys the obstacle shunts such as each conical barrel and the water horse, the traffic accident detection device 1 applied to road maintenance work is respectively arranged on each conical barrel and the water horse. Preferably, the traffic accident detection device 1 applied to road maintenance operation is annular in shape as a whole and can be directly sleeved on a bucket cone (prismatic or conical) of a conical bucket to be fixed. In the case of a water horse, the traffic accident detecting apparatus 1 applied to the road maintenance work may be placed on its horizontal surface or may be fixed to its body by a mounting member such as a bracket, an adhesive tape, or the like, which is not limited by the present invention.
As shown in fig. 4, the internal circuit structure of the traffic accident detection apparatus 1 applied to road maintenance work mainly includes: the sensing module 41, the processing module 42, and the communication module 43, wherein the sensing module 41 and the communication module 43 are electrically connected to the processing module 42, respectively.
In detail:
the sensing module 41 is configured to sense a posture change of the traffic warning obstacle, and preferably employs a posture sensor (similar to a gyroscope) capable of generating a corresponding sensing result according to the posture change when the traffic warning obstacle moves, slightly shakes, largely tilts, or falls over.
The Processing module 42 is a general-purpose Processor, such as a Central Processing Unit (CPU), a Network Processor (NP), etc., and may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other Programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The processing module 42 is configured to enable the communication module 43 to send a detection result signal outwards when the sensing module 41 senses the posture change of the traffic warning obstacle.
Further, the processing module 43 may determine whether to enable the communication module 43 to send a detection result signal according to the posture change sensed by the sensing module 41; if the attitude change meets a preset condition, enabling the communication module to send a detection result signal outwards; otherwise, the communication module is not enabled to send the detection result signal to the outside. For example, when the sensing module 41 senses that the inclination is 45 degrees, the processing module 42 does not make the communication module 43 transmit a signal to the external alarm device 2, and when the sensing module 41 senses that the inclination is 45 degrees or more, the processing module 42 makes the communication module 43 transmit a signal to the external alarm device 2. For another example, when the sensing module 41 senses that the movement is 10cm, the processing module 42 does not make the communication module 43 transmit a signal to the external alarm device 2, and when the sensing module 41 senses that the movement is 10cm or more, the processing module 42 makes the communication module 43 transmit a signal to the external alarm device 2.
By the design, when a running vehicle rushes into an operation area maintained by the conical barrel due to factors such as fatigue driving or mechanical failure and the like, the posture sensor changes the posture due to the action of external force due to the collision of the vehicle to the conical barrel, the communication module is promoted to send a signal to external alarm equipment, and the alarm equipment is enabled to start high-decibel sound and photoelectricity to alarm, so that the beneficial effects of warning operators for emergency avoidance and escape are achieved; when the posture of the conical barrel is slightly changed due to crosswind or other non-vehicle reasons, the alarm device does not give an alarm, so that the occurrence of false alarm is reduced.
The communication module 43 is configured to send the detection result signal to the external alarm device 2 under the control of the processing module 42, so that the alarm device 2 gives an alarm. The communication module 43 may adopt a ZIGBEE module, a LORA module, a 5G module, or other non-delay transmission module. Preferably, the communication module 43 is a LORA module, as shown by reference numeral d in fig. 3. The LORA technology is mature, the cost is low, the electromagnetic wave winding capacity is strong, the transmission distance is long, dozens or more than hundreds of communication signals can be effectively acquired at one time without time delay, and therefore signals are sent to the alarm device 2 in time to enable the alarm device to rapidly give an alarm.
In addition, as shown in fig. 3, the traffic accident detecting apparatus 1 according to the present application further includes: and the indication module a, the lithium battery slot b and the charging interface c are respectively electrically connected with the processing module. The indication module a may be a working indicator lamp, an LED electronic screen, etc. for displaying the current working state of the traffic accident detection apparatus 1. A lithium battery can be placed in the lithium battery tank b to provide power for the traffic accident detection device. Alternatively, the traffic accident detection apparatus 1 may be provided with a rechargeable lithium battery, and the charging interface C may be of a Type-A, Type-B, Type-C or the like.
In light of the above, the alarm device 2 in fig. 2 is an electronic device having a communication function (including an antenna) and an alarm function (e.g., an acoustic alarm and an optical alarm), and preferably includes a LORA base station, so that data communication can be performed between the alarm device 2 and the traffic accident detection apparatus 1 disposed on each of the conical barrels and the water horses through the LORA.
Preferably, the LORA base station is mounted on a vehicle or other transportation device. The transportation equipment moves in a construction area, the LORA base station moves along with the movement of the transportation equipment, and signal transmission is carried out between the LORA base station and each traffic accident detection device 1 through an LORA protocol in the moving process.
The traffic accident detection device applied to road maintenance operation can be sleeved on the cone barrel or hung on the water horse by road maintenance operators by utilizing the original warning obstacles such as the cone barrel without specially manufacturing the cone barrel, the water horse and the like, and if vehicles run into a construction isolation area to collide with the traffic warning obstacles such as the water horse, the cone barrel and the like, the alarm equipment immediately sends out an alarm prompt, thereby winning more escape time for the road maintenance operators, improving the operation safety of the road construction operators and effectively avoiding traffic accidents on the road.
The traffic accident early warning system applied to road maintenance operation, when in actual application, a worker presses a 'reset key' of the alarm device to start the alarm device, and at the moment, the alarm device sends a reset signal to all traffic accident detection devices on the conical barrels, so that sensors of all traffic accident detection devices are synchronously reset and enter the working state of detecting the postures of the conical barrels at the moment. In case of the falling or displacement of the cone-shaped barrel caused by external force, the traffic accident detection device sends out electric pulses to the alarm device, the alarm device immediately sends out high-decibel and high-volume warning whistle, and can also start the warning lamp to carry out double warning, so that the aim of warning road maintenance workers to avoid vehicles possibly collided with the cone-shaped barrel in time is fulfilled, if non-vehicles such as crosswind and the like fall down the cone-shaped barrel, the false alarm condition is generated, the maintenance workers can observe the situation, after the safety is ensured, the reset key of the alarm device is pressed again, and the next early warning work is continued.
In conclusion, the traffic accident detection device and the early warning system applied to the road maintenance operation can warn traffic dangers in advance for road constructors working at a countersunk head, prolong the life time of avoiding the dangers, create a good safety foundation for the construction of road maintenance, effectively overcome various defects in the prior art and have high industrial utilization value.
