Detailed Description
The invention is further described below with reference to the accompanying drawings and specific examples.
Embodiment 1, referring to fig. 1-2, a tunnel lighting dome lamp includes a lighting module, a housing, and a circuit board disposed in the housing, wherein the circuit board includes a microcontroller module 101, and a wireless communication module 102 and an ultrasonic transceiver module 103 connected to the microcontroller module 101; the ultrasonic transceiver module 103 is used for detecting whether a newly added stationary object exists in a preset lane area, and the direction of the probe can be vertically downward or deviated to the left or right of the lane on the basis of vertical downward according to the actual installation position of the tunnel lighting dome lamp; when detecting that a newly added stationary object exists on the lane, the microcontroller module 101 controls the wireless communication module 102 to externally send a detection signal including object existence information and an equipment number; when the ultrasonic transceiver module 103 detects that a newly added stationary object exists on the lane and the wireless communication module 102 does not receive a detection signal of the tunnel lighting dome lamp in front of the lane within a preset time period before and after, the microcontroller module 101 controls the wireless communication module 102 to upload an alarm signal including object alarm information and a device number. The tunnel lighting dome lamp determines the front-back relation of the equipment in the driving direction of the lane by comparing the equipment number in the detection signal with the equipment number of the tunnel lighting dome lamp. In this embodiment, the wireless communication module 102 includes two types of communication modules with different purposes, one is used for data interaction with similar devices, and a wireless radio frequency transceiver module is preferred; the other is used for data interaction with the data platform, an NB-IoT communication module, a GPRS communication module, an LoRa communication module and the like can be selected, and the NB-IoT communication module is preferred.
In this embodiment, the ultrasonic transceiver module 103 determines whether a stationary object exists in a preset lane area according to the detected ultrasonic data; the specific principle is as follows: the ultrasound data includes a sustained echo time and an echo intensity value corresponding to the echo time. The ultrasound transceiver module 103 has several advantages: firstly, the launching angle is larger, and the detectable preset lane area range is larger; the ultrasonic transceiver module 103 can detect the intensity value of the reflected echo, that is, the echo intensity value, in addition to obtaining the distance data with the nearest object according to the reflected ultrasonic wave, and when the ultrasonic transmitter transmits the ultrasonic wave to a certain object, the ultrasonic receiver does not stop timing when receiving the reflected echo, so as to obtain the echo intensity value and the echo time; since the ultrasonic wave has a large beam angle, there may be many reflection points capable of reflecting the ultrasonic wave on the surface of the object within the beam angle range, and the distance between the reflection point and the ultrasonic device is large or small, the ultrasonic transceiver module 103 may continuously detect the echo intensity value corresponding to the echo time as the echo time increases. If no vehicle exists in the preset lane area, the echo time point corresponding to the ground at the nearest distance from the tunnel lighting dome lamp vertically downwards is taken as a demarcation point, the echo time point can be called a demarcation time point, the echo intensity value corresponding to the demarcation time point has an echo intensity value peak with larger intensity, the echo intensity value corresponding to the echo time period smaller than the demarcation time point approaches to zero, and the echo intensity value corresponding to the echo time period larger than the demarcation time point has vertical change; under the condition that the condition of a lane road surface is not changed and no vehicle exists, the echo time points corresponding to all wave crests in ultrasonic data obtained through multiple detections basically do not change or change slightly.
If vehicles exist in the preset lane area, an obvious new strong echo intensity value wave peak appears in the echo time period smaller than the demarcation time point, or an obvious change occurs in the echo time point corresponding to the wave peak in the echo time period larger than the demarcation time point, namely, the new echo intensity value wave peak appears or the original echo intensity value wave peak disappears; these significant changes are due to vehicle reflections; in general, the tunnel lighting dome lamp of the embodiment can comprehensively judge whether an object or a vehicle exists according to the data of the continuous echo time and the echo intensity value corresponding to the echo time, which are detected by the ultrasonic transceiver module 103, so that the judgment is more comprehensive and accurate; and thirdly, the ultrasonic data can be further used for assisting in judging conditions such as high temperature, flame, smoke and the like, the high temperature and the flame can cause air flow aggravation so as to cause the echo intensity value corresponding to the echo time point in the multi-time ultrasonic detection signal to fluctuate up and down violently, and the smoke can cause the echo intensity value corresponding to the echo time point in the multi-time ultrasonic detection signal to attenuate. The specific principle can be seen in patent CN111179561A (a kitchen ignition monitoring and judging method, kitchen fire monitoring and judging method).
The tunnel lighting dome lamp of this embodiment is the same with current tunnel lighting dome lamp mounting means, all uses in highway tunnel, along the inside top of tunnel direction interval preset distance distribution and fixed mounting, also has the illumination function in the function. On the basis, the tunnel lighting dome lamp of the embodiment also has the function of detecting the static object on the preset lane area, wherein the static object is exemplified by a parking vehicle in the embodiment. When the existence of a static object in the preset lane area is detected, although the tunnel lighting dome lamp can determine that a parking vehicle exists in the lane, the parking vehicle cannot be determined to be illegally parked or parked due to the fact that a front road is blocked; the first option is to directly upload detection signals including object existence information and equipment numbers to a data platform, and the first option is that when traffic jam or the like occurs, all tunnel lighting top lamps along a tunnel detect the existence of objects and upload detection signals to the data platform, so that the concurrent pressure of an NB network is increased, the data platform needs to receive and process a large amount of data to increase the platform burden, and the source of traffic jam in the tunnel needs to be additionally judged; in the embodiment, a second option is adopted, namely, the detection signal is not directly uploaded to the data platform, but the detection signal is firstly sent to other tunnel lighting top lamps at the periphery through the wireless radio frequency transceiver module; when the tunnel lighting dome lamp detects that a newly-added static object exists on the lane, and the detection signal of the tunnel lighting dome lamp in front of the lane is not received within the preset time, that is, when the lane in front of the tunnel lighting dome lamp is smooth, the warning signal including the object warning information and the equipment number is uploaded to the data platform through the NB-IoT communication module, in other words, even if the second mode is in traffic jam, only one tunnel lighting dome lamp which detects the object finally uploads the warning signal to the data platform. As for how the tunnel lighting dome lamp judges whether the detection signal belongs to the tunnel lighting dome lamp in front of the lane, the fact that the received detection signal comes from the tunnel lighting dome lamp in front of or behind the lane can be determined by comparing the equipment number of the equipment with the equipment number in the detection signal, and the tunnel lighting dome lamp is required to be installed from large to small or from small to large according to a certain sequence condition along the vehicle advancing direction when being installed.
In the existing tunnel, the conditions of fault parking, illegal parking or cargo scattering and the like can occur, and the conditions are not easy to be found by other vehicles in time in the tunnel due to the visual field, so that traffic accidents are easy to cause and even secondary traffic accidents are easy to cause. According to the invention, the existing tunnel lighting dome lamp with single function is improved, so that the tunnel lighting dome lamp can collect data to detect whether objects or vehicles exist on a lane, and the wireless networking interaction data of the devices in the signal range is used, so that each tunnel lighting dome lamp node in the tunnel is a data collector and is also a data analyzer, edge calculation is carried out by combining the data of other surrounding tunnel lighting dome lamps, and an alarm signal is uploaded only when the comprehensive analysis judgment is that the tunnel lighting dome lamp is at the source of parking. The tunnel lighting dome lamp can reduce the concurrent pressure of an NB (NB) network, reduce the data volume and times received by a data platform, and improve the reliability of data communication.
In the highway tunnel, except that the situations of vehicle parking, cargo scattering and the like may occur, fire accidents needing to be handled urgently, such as spontaneous combustion, fire, explosion and the like of the vehicle, may also occur, and the prior art cannot timely monitor the fire accidents and report the fire accidents to a fire department, so that a driver or drivers of other passing vehicles are often required to actively call an alarm, and the possibility of delay is very high. In order to solve the hidden trouble, the circuit board in the tunnel lighting dome lamp of the embodiment further includes an environmental parameter detection module 104 connected to the microcontroller module 101, and the environmental parameter detection module 104 is configured to detect an environmental parameter of the surrounding environment; the microcontroller module 101 controls the wireless communication module 102 to externally send environmental parameters and environmental data including the equipment number; when the environmental parameters detected by the tunnel lighting dome lamps change more than the preset conditions compared with the environmental parameters of the surrounding tunnel lighting dome lamps, the microcontroller module 101 controls the NB-IoT communication module to upload alarm signals including fire alarm information and device numbers to the data platform. The environmental parameter detection module 104 includes at least one of a smoke concentration detection module, a temperature detection module, a humidity detection module, a flammable and explosive gas detection module, and a toxic gas detection module, and can detect environmental parameters such as smoke concentration, temperature, humidity, flammable and explosive gas concentration, and toxic gas concentration, respectively.
