Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] The purpose of the present utility model is to provide a guardrail monitoring device with solar hybrid power supply in view of the defects of the prior art.

[0028] Embodiment 1

[0029] This embodiment provides a guardrail monitoring device with solar hybrid power supply, as Figure 1 shown, including a solar module 11, a lithium battery module 12, a charging management module 13, a monitoring module 14, a central processor module 15, and a communication module 16; the solar module 11 is respectively connected to the charging management module 13, the monitoring module 14, the central processor module 15, and the communication module 16, the lithium battery module 12 is respectively connected to the charging management module 13, the monitoring module 14, the central processor module 15, and the communication module 16, and the central processor module 15 is respectively connected to the monitoring module 14 and the communication module 16.

[0030] The monitoring module 14 is used to monitor the data information corresponding to the guardrail and send the monitored data information to the central processor module.

[0031] In this embodiment, the monitoring module 14 may include an attitude monitoring module and other sensors (such as a temperature and humidity sensor, a displacement sensor, etc.); it should be noted that in the monitoring of the guardrail, the attitude change of the guardrail is particularly important, which can timely know the direction and position of the guardrail, and then determine whether there is a problem with the guardrail; therefore, this embodiment does not elaborate on other sensors, and they can be set according to actual needs.

[0032] The attitude monitoring module uses the attitude sensor chip SC7A20ETR of Silan Micro to monitor the attitude state of the guardrail, determine the direction and position of the guardrail, and send the monitored attitude state to the central processor module 15.

[0033] The central processor module 15 uses the single-chip microcomputer GD32L233CCT6 of Beijing GigaDevice Semiconductor Inc. to receive and process the data information of the attitude monitoring module and other sensors, and send the processed data information to the communication module 16.

[0034] The communication module 16 is for NB-IoT communication. The NB-IoT communication uses the BC26YCNFA module of Shanghai Quectel Wireless Solutions Co., Ltd., and is paired with a supporting China Telecom Internet of Things SIM card, which is used to wirelessly transmit the processed data to an external platform.

[0035] The solar module 11 uses a PET-type solar panel with a size of 83MM * 42MM 5V100MA, which is used to convert solar energy into electrical energy, supply power to the monitoring module 14, the central processor module 15, and the communication module 16, and also send the electrical energy to the charging management module 13.

[0036] The charging management module 13 uses a dedicated charging management chip CN3170 (Ru Yun Electronics) to manage the charging process of the solar module 11 and the lithium battery module 12, that is, the electrical energy converted by the solar module 11 is used to charge the lithium battery module 12 through the charging management module 13.

[0037] The lithium battery module 12 uses 18650 lithium batteries, which are used to store the electrical energy charged by the charging management module 13 and supply power to the monitoring module 14, the central processor module 15, and the communication module 16 when the electrical energy of the solar module 11 is insufficient (such as at night or on cloudy days).

[0038] It should be noted that the monitoring method, processing method, etc. involved in this embodiment can be implemented by the specific models of the products adopted, and this embodiment does not improve the methods.

[0039] In this embodiment, the external platform is the network layer platform 17. The network layer platform 17 is communicatively connected to the guardrail monitoring device through the communication module 16. The network layer platform 17 is also connected to the network management platform 18 and the mobile phone APP 19, so that the guardrail monitoring device wirelessly transmits the processed data to the network layer platform 17 through the communication module 16, and then the network platform transmits it to the network management platform 18 and the mobile phone APP 19, as Figure 2 shown.

[0040] As a renewable energy source, solar energy can provide continuous and stable power supply for the guardrail monitoring device through the solar panel. Moreover, the solar panel is also connected to the 18650 lithium battery through the charging management module. By mixing the power supply of the solar panel and the lithium battery, the solar energy is used to supply power to the guardrail device and charge the lithium battery during the day, while the lithium battery provides power at night or on cloudy days, thus ensuring the normal operation of the device all day long and ensuring the normal and stable operation of each functional module on the guardrail device.

[0041] The specific usage method of a guardrail monitoring device with solar hybrid power supply in this embodiment is as follows:

[0042] 1. After the installation of the guardrail monitoring device, short-circuit the contacts on the device and the magnetic switch will be attracted for more than 10 seconds to power on. There is a corresponding indicator light on the device to indicate the device status. The flashing of the indicator light means that the device is successfully powered on and activated. At the same time, the device will automatically calibrate the tilt value internally, which is used as a reference. Subsequent relevant alarms will refer to this reference value.

[0043] 2. In the guardrail monitoring device, the solar panel is responsible for converting solar energy into electrical energy and supplying power to the guardrail device. The solar panel also charges the 18650 lithium battery through the charging management module so that when the solar energy is insufficient (such as at night or on cloudy days), the 18650 lithium battery can supply power to the guardrail device.

[0044] 3. After the installation of the guardrail monitoring device, it is used to monitor the attitude status of the guardrail in real time and transmit the data to the central processor. The central processor processes the received data and sends it to the network layer platform in a wireless network manner through the NBIOT communication module. Finally, the data is pushed to the corresponding network management platform and the mobile APP, and the point reporting information can be received.

[0045] 4. After the guardrail monitoring device is powered on and starts up normally, scan the QR code pasted on the device through the mobile APP. The QR code contains the IMEI number of the NBIOT module in the device and the MAC address information of the device. After scanning, the device-related information will be automatically recognized. By simply adding the device number and device type, it can be added to the mobile APP platform for subsequent viewing and management. After successful addition, in addition to viewing some corresponding statuses, relevant alarm parameters can be set on the platform if needed.

[0046] 5. After the installation of the guardrail monitoring device, when there is no tilt, vibration, etc., the device will automatically enter the sleep mode and be in a low-power state for a long time. When there is tilt, vibration, etc., after being awakened, the device will push the corresponding alarm to the mobile APP platform. The mobile APP platform can receive the corresponding alarm information in time, and relevant maintenance personnel can judge and respond to the corresponding fault situation in time after receiving it. When the tilt fault is processed and restored, the guardrail monitoring device will also push the corresponding fault recovery alarm to indicate that the point on the device side is normal.

[0047] This embodiment provides a power supply system for a guardrail monitoring device that is efficient, economical, and environmentally friendly. It not only reduces the maintenance cost, reduces environmental pollution, but also improves the power supply reliability and service life of the device, and further enhances the road traffic safety level.

[0048] Note that the above is only the preferred embodiment of the present utility model and the applied technical principles. Those skilled in the art will understand that the present utility model is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present utility model. Therefore, although the present utility model has been described in more detail through the above embodiments, the present utility model is not limited to the above embodiments. Without departing from the concept of the present utility model, more other equivalent embodiments can be included, and the scope of the present utility model is determined by the scope of the appended claims.
