Problems solved by technology

However, urban road guardrails must be in a movable state due to the need for safety, so the mains power cannot be used. In the existing guardrail monitoring results, some or all circuits are in a normal working state from time to time, and there is a problem of relatively large circuit power consumption. Prolonged rainy weather, especially in the rainy season, can easily exhaust the power of the alarm system and lose the alarm function; at the same time, the system design is too complicated, which is not conducive to miniaturization, so it is not easy to install in the road guardrail or will increase the volume of the guardrail, which is not easy good for road safety

Embodiment 1）

[0054] See figure 1 , the urban road guardrail state monitoring device in this embodiment includes a solar module 101 , a detection unit 102 , an energy storage unit 104 and at least one side pressure reed switch 103 . See Figure 5 , wherein the solar module 101 includes a solar cell panel 1011 and a protective cover 1012 . The area of ​​the solar panel 1011 is 4cm*8cm, and the performance parameters are as follows: when the outdoor light intensity is 500lx on a cloudy day, the output open-circuit voltage is 5.5V, and the short-circuit current reaches 5mA, which ensures that even in cloudy days, the tiny current can flow to the circuit. Sufficient standby current is provided, and there is also a weak charging current to charge the energy storage unit 104; when the sunlight intensity outdoors is 10000lx on a sunny day, the output open-circuit voltage is 7V, and the short-circuit current reaches 30mA, which can fully charge the 900mAH Li-MH battery within 4 days Electricity; ...

Embodiment 2）

[0070] This embodiment is basically the same as Embodiment 1, and the difference lies in that: the burst power storage circuit 1021 adopts a Farad capacitor.

Embodiment 3）

[0072] This embodiment is basically the same as Embodiment 1 or 2, except that some or all of the solar module 101 , the detection unit 102 and the energy storage unit 104 are attached to any position of the guardrail.

Abstract

The invention relates to an urban road guardrail system and a working method thereof. The system includes at least one guardrail unit and an urban road guardrail state monitoring device; the guardrail units are connected together by a common column; the urban road guardrail state monitoring device includes a solar module , detection unit, energy storage unit and side pressure reed switch; detection unit is composed of burst power storage circuit, power management circuit, microprocessor circuit and wireless communication module. The guardrail posture is normal, the side pressure reed switch is closed, the detection unit is in standby state, and the solar module charges the energy storage unit; the guardrail posture is abnormal, the side pressure reed switch is disconnected, and the power management circuit of the detection unit controls the power supply to the microprocessor circuit , the microprocessor circuit controls the charging of the burst power storage circuit and makes the wireless communication module send out the abnormal information of the guardrail after the charging is completed. After the transmission is completed, the power management circuit enters the low power consumption mode and waits for maintenance. The urban road guardrail system has a long standby time.

Description

technical field [0001] The invention relates to the field of urban road guardrail maintenance and intelligent monitoring, in particular to an urban road movable guardrail system with a state monitoring device and a working method thereof. Background technique [0002] On all kinds of highways, especially urban roads, movable road guardrails have become one of the necessary traffic settings. They are widely used and widely distributed, resulting in a huge workload of maintenance and overhaul of guardrails. Traffic accidents and bad weather lead to guardrails. The phenomenon of shifting, lying, and rolling over occurs at a high rate, and it is extremely difficult to accurately locate the guardrail at the first time, which brings great inconvenience to the maintenance of the guardrail, and is also prone to secondary traffic accidents, reducing people's sense of safety when traveling. At present, there are also many researches on the intelligent management of road traffic guardr...
