[0001] The utility model relates to the technical field of environmental monitoring, and in particular to a portable intelligent monitoring and early warning device for sand accumulation on railway tracks in desert areas. Background Art
[0002] With the development of infrastructure in western my country, the number of railways passing through the western region has also increased. However, sandstorms are severe in some parts of the west, and the activities of wind and sand flows have a great impact on the normal operation of the railways. To solve this problem, it is necessary to set up corresponding sand prevention systems and early warning equipment on both sides of the railway. The commonly used early warning technologies are laser ranging or relying on passing vehicles as excitation sources or sensor carriers.
[0003] However, the existing sand accumulation monitoring and early warning technology has major shortcomings, which are mainly manifested in three aspects: first, the cost is high and it is difficult to apply on a large scale; second, the results are not robust enough. For example, image recognition through natural light cameras is prone to false alarms under naturally changing lighting conditions; third, when relying on passing vehicles as the excitation source, the condition of passing vehicles is required, which cannot meet the needs of intelligent monitoring.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0024] The embodiment of the present application provides a portable intelligent monitoring and early warning device for sand accumulation on railway tracks in desert areas, which can solve the technical problems in the prior art that early warning of sand accumulation is not timely and is prone to false alarms.
[0025] Figure 1 It is a structural schematic diagram of a portable intelligent monitoring and early warning device for sand accumulation on railway tracks in desert areas provided in an embodiment of the present application. The intelligent monitoring and early warning device for sand accumulation on railway tracks in desert areas in the present application includes a collection part and an action part. Specifically, the collection part includes an outer shell 1, and a plurality of photoresistor sensors 2 arranged longitudinally outside the outer shell 1 are used to sense the brightness of external light according to the number of buried photoresistors, and a fill light 3 arranged on one side of the photoresistor sensor 2 for fill light in a night environment, and a power supply battery 4 is arranged in the outer shell 1; the action part includes a central processing unit 5 arranged in the outer shell 1 for receiving the light signal sensed by the photoresistor sensor 2 and making a corresponding early warning, and a communication component 6 for transmitting data of the central processing unit 5 to a monitoring center is provided at the top of the outer shell 1.
[0026] During installation, the outer shell 1 is set on the side of the track, and the side where the photoresistor sensor 2 is set is away from the track, so that the photoresistor sensor 2 and the fill light 3 are set facing the wind. Multiple photoresistor sensors 2 are set vertically, responsible for sensing external light and converting light intensity into analog electrical signals. The number of photoresistor sensors 2 is determined according to actual use requirements, and there is no specific restriction in the present application. When sand accumulates on the rails, part of the photoresistor sensors 2 set at the bottom will be buried under the sand and dust first. The deeper the sand accumulation, the less external light can penetrate the sand, resulting in the overall light sensed by the photoresistor sensor 2 becoming darker, and the analog electrical signal that can be converted will also be weakened. Conversely, the analog electrical signal will be enhanced. Furthermore, the photoresistor sensor 2 can also be used in conjunction with an amplifier. The input end of the amplifier is connected to the photoresistor sensor 2, and the output end of the amplifier is connected to the central processor 5 to increase sensitivity and reliability.
[0027] The dimming of light at night will also cause the analog electrical signal emitted by the photoresistor sensor 2 to weaken. Therefore, in order to improve the accuracy of detection and reduce measurement errors, a fill light 3 is set on one side of the photoresistor sensor 2 to provide a stable light source for the photoresistor sensor 2 at night, effectively eliminating the impact of weak ambient light at night. Furthermore, the fill light 3 can flexibly set the working time according to the use area and season. The power supply battery 4 is set in the outer shell 1, mainly used to provide power for the entire device. The power supply battery 4 can select ordinary storage type or solar cell according to the inspection frequency, and the monitoring equipment in this application can set the sleep mode. When a monitoring work is completed, it automatically enters sleep mode, and the power consumption during operation is not high. Therefore, setting the power supply battery 4 can meet the detection needs.
[0028] The central processing unit 5 is arranged in the outer shell 1, and is mainly used to collect the analog electrical signal emitted by the photoresistor sensor 2, and the central processing unit 5 can calculate the intensity of the light in the external environment by the strength of the analog electrical signal. Furthermore, the minimum threshold of the analog electrical signal received by the central processing unit 5 can also be set in advance. When the analog electrical signal is lower than the minimum threshold, the central processing unit 5 sends a sand accumulation alarm signal. The chip in the central processing unit 5 integrates an eight-channel analog-to-digital converter, which is responsible for collecting the analog electrical signal of the photoresistor sensor 2 and simulating the light intensity in the environment, and can also be responsible for functions such as communication and system control.
[0029] The communication component 6 is wireless communication and is arranged on one side of the top of the outer shell 1. It is connected to the electrical serial port of the central processor 5 and transmits data. The communication component 6 needs to be configured with the monitoring center server in advance, and can send the information output by the central processor 5 directly to the terminal computer in time for the staff to do corresponding processing. The communication component 6 is arranged on the top of the outer shell 1. Its setting position is relatively high, which can also avoid being buried by accumulated sand and causing poor communication. Furthermore, if the use environment is harsh and the wind and sand are strong, a wind shield can be set around the communication component 6 without affecting the normal operation of the communication component 6.
[0030] Furthermore, in one embodiment, the outer shell 1 is a closed cylinder. The early warning device in the present application is mainly used at railroad tracks in desert areas where there is strong wind and sand and the natural environment is relatively harsh. The cylindrical shape helps to reduce the thrust generated by wind flow. Furthermore, the outer shell 1 can also be a column with a teardrop-shaped cross-section, with its narrower side facing the wind. The full enclosure of the outer shell 1 can effectively isolate external sand and water vapor, preventing sand or water vapor from entering the outer shell 1 and affecting the normal operation of the equipment.
[0031] Furthermore, the monitoring and early warning equipment in the present application is usually connected to the ground or to a track. Therefore, in order to facilitate fixation, a fixed base 7 is provided at the bottom of the outer shell 1. The setting methods of the fixed base 7 include but are not limited to a disc shape, a right-angle code, etc., which can facilitate the outer shell 1 to be connected to the ground or the track. There is no specific restriction in the present application. Furthermore, a connector 8 for connecting to the ground is provided on the fixed base 7. The connector 8 includes but is not limited to connectors such as bolts, ground nails, clamps, etc. that pass through the base.
[0032] Furthermore, the outer shell 1 is provided with a plurality of first openings 201 arranged longitudinally, the photoresistor sensor 2 is arranged in the first opening 201, a second opening 301 is arranged above each first opening 201, and the fill light 3 is arranged in the second opening 301. Figure 2 A left side schematic diagram of an outer shell 1 in a portable intelligent monitoring and early warning device for sand accumulation on railway tracks in desert areas provided in an embodiment of the present application, wherein the junction between the photoresistor sensor 2 and the photon faces outward and a fill light 3 is arranged above each photoresistor sensor 2. It should be noted that the number of fill lights 3 and the number of photoresistor sensors 2 are both multiple, and the number of fill lights 3 is not less than the number of photoresistor sensors 2, which can effectively improve the uniformity of fill light and help obtain more accurate and scientific monitoring results.
[0033] Furthermore, the fill light 3 is an LED (Light-Emitting Diode) lamp, which is a commonly used light-emitting component in the prior art. It has the characteristics of long life, low energy consumption, and low manufacturing cost. It can be well applied to the use scenario of the early warning device in this application, and will not be elaborated here.
[0034] Furthermore, the connection end of the communication component 6 is electrically connected to the central processing unit 5 via the communication interface 601. In one embodiment of the present application, the communication component 6 is a LoRa (a low-power local area network wireless standard for receiving and sending radio signals) antenna. The LoRa antenna has a long transmission distance and strong anti-interference ability. It can be flexibly configured with relay, sleep and other modes, and is connected to the central processing unit 5 via the communication interface 601 to facilitate data transmission. It is suitable for use in unmanned remote areas. The LoRa antenna sends data via a radio frequency antenna, and a LoRa data receiving gateway must be equipped in the terminal computer of the monitoring center in advance.
[0035] The working process of the monitoring and early warning equipment in this application is as follows: after the equipment is installed and powered on, the working mode of the communication component 6 is configured, and the corresponding receiving gateway is configured on the terminal computer of the monitoring center. When the environmental light monitoring is started, the photoresistor sensor 2 first obtains the external light level according to the number of buried objects, and converts the external light into an analog electrical signal of corresponding intensity. The central processing unit 5 calculates the degree of sand accumulation through the strength of the analog electrical signal. When the analog electrical signal emitted by the photoresistor sensor 2 is lower than the threshold set in advance, the central processing unit 5 issues a warning, and then the communication component 6 sends the calculated result to the terminal computer of the monitoring center. After executing an environmental light monitoring and reporting, the equipment enters a sleep state. When the next monitoring is required, the equipment starts working again, and the monitoring is cyclically carried out.
[0036] The intelligent monitoring and early warning equipment for sand accumulation on railway tracks in desert areas in the present application adopts a measurement method of a photoresistor sensor 2 in combination with LED fill light technology, which effectively solves the monitoring errors caused by environmental factors at night, improves the accuracy of the monitoring results, and greatly reduces the false alarm rate of the equipment; compared with the wired transmission in the prior art, the present design adopts the LoRa wireless communication technology based on the Internet of Things, which can realize stable long-distance data communication, and the signal on the device side will not be affected by the obstruction of sand accumulation; at the same time, the monitoring and early warning equipment in the present application supports deep sleep mode, has low energy consumption, can extend the use time, and the overall manufacturing cost of the equipment is low, can be laid over a large area, has a small overall size, can be flexibly set on unmanned railway tracks or around the railway tracks, and is also convenient for later installation and maintenance.
