Description

Technical Field

[0001] The present invention relates to the technical field of rain gauges, and particularly to an integrated dual-channel low-power rain gauge. Background Art

[0002] Currently, ground rainfall monitoring technology mainly relies on self-recording rain gauges. Some hydrological stations with on-site personnel still retain manual measurement methods such as siphon rain gauges and manual rain gauges. Data reporting is mainly through an external instrument box. Equipment such as acquisition terminals, communication modules, and solar charging controllers are all integrated in a sealed instrument box. The solar panel is connected to the instrument box through a connecting wire; satellite communication requires adding a satellite terminal to the instrument box, and a satellite antenna is connected outside the instrument box through a cable. Such a rainfall monitoring station has a large number of devices, complex installation and maintenance, and high costs. Summary of the Invention

[0003] To solve the above problems, the present invention discloses an integrated dual-channel low-power rain gauge, which is quick and convenient to install, without the need to externally connect any accessories. The device can be installed by simply fixing it on a fixed base; installation, debugging, operation, and maintenance are convenient, greatly reducing construction and maintenance costs, and having good application prospects. It is a full-scale technical solution for the second line of defense in the rain and water situation monitoring and forecasting "three lines of defense".

[0004] The specific solution is as follows:

[0005] An integrated dual-channel low-power rain gauge, characterized in that: it includes a rain cylinder and an integrated control box arranged on the side of the rain cylinder. The integrated control box includes a front panel and a rear shell arranged front and back. The front panel is inclined, and a solar panel is provided on the upper section of its surface. After a certain distance from the solar panel, the lower section protrudes forward and internally houses an inclined Beidou satellite antenna. A Beidou satellite antenna fixing bracket, a circuit main board, a lithium battery, and an aviation plug are installed between the front panel and the rear shell. The Beidou satellite antenna fixing bracket is used to install and support the Beidou satellite antenna. The circuit main board includes a low-power microcontroller, a 4G / 5G module, a Beidou communication module, a Beidou positioning module, a switch input interface, a Bluetooth module, a USB interface, and a charging control module. The lithium battery is used for power supply. There are two aviation plugs, which are placed under the inner side of the rear shell.

[0006] Further, the 4G / 5G module is the main channel, and the Beidou communication module is the backup channel. Data transmission adopts a dual-channel working mode. In the normal mode, 4G / 5G communication is preferentially used. When 4G / 5G communication fails, Beidou communication is enabled, or Beidou communication can also be directly used through settings. The dual-channel mode can be used in places where network signals cannot cover, or in extreme environmental conditions (such as natural disasters causing network signal interruptions).

[0007] Furthermore, both the Beidou communication module and the Beidou positioning module are connected to the Beidou satellite antenna. This antenna supports Beidou short message communication and positioning functions.

[0008] Furthermore, the digital input interface can be connected to a single-layer tipping bucket device and a double-layer tipping bucket device. The single-layer tipping bucket has a simple, reliable, and stable structure, is easy to maintain and use. However, when used for small resolution, its accuracy is affected. The double tipping bucket rain gauge is divided into upper and lower layers. The upper layer is a transition tipping bucket, and the lower layer is a measuring tipping bucket. The double tipping bucket can improve the accuracy of rain measurement. There are individual products used in tipping bucket rain gauges with a resolution of 0.1 mm, but their structures are complex and their reliability and stability are poor.

[0009] Furthermore, the Bluetooth module and the USB interface are used for communication with remote terminals, including configuring parameters, sending commands, viewing data, and software upgrading, etc. Among them, the Bluetooth module is configured through the mobile phone side, and the USB interface is configured through the PC side. The configured parameters include station number, transmission protocol, rain gauge accuracy, rain threshold, acquisition interval, storage interval, sending interval, transport layer protocol, IP address or domain name, and network port. Among them, the transmission protocol includes ASCII for hydrological monitoring data communication protocol, HEX for hydrological monitoring data communication protocol, water resources transmission protocol, etc.; and it can send commands such as restart, reset parameters, clear storage, set time, collect once immediately, and collect and send. In addition, it also has a remote parameter configuration function. In addition to locally configuring the above parameters using USB and Bluetooth, the parameters can also be configured through 4G / 5G, and the relevant parameters can be configured through the server of the central station.

[0010] Furthermore, the charging control module is used to control the charging of the lithium battery.

[0011] Furthermore, the lithium battery consists of 25 single 18650 lithium batteries with a single capacity of 3.7V and 3000mAh, and the total capacity is 75Ah. It adopts a large-capacity battery design.

[0012] Furthermore, the aviation plug is a four-core waterproof plug. One is connected to the tipping bucket device, and the other is reserved for backup. It can be externally connected to a solar panel, a battery, and other devices.

[0013] Furthermore, an electronic level is also built-in, which is used to report an alarm signal when the rain gauge is tilted, notifying the maintenance personnel that the equipment needs maintenance. This can reduce the number of regular inspections and reduce the work intensity of the maintenance personnel.

[0014] The beneficial effects of this application are as follows:

[0015] 1. A dual-channel communication design is adopted. The main channel is 4G / 5G communication, and the backup channel is Beidou communication (supporting the second-generation and third-generation Beidou). It has a wide range of applications, including single rainfall monitoring devices in the wild without satellite channels, effectively ensuring the stability and reliability of rainfall information transmission at stations in remote mountainous areas with weak communication signals.

[0016] 2. An integrated design is adopted. The functions of data acquisition, storage, and transmission are integrated in an integrated control box, including 4G / 5G antennas, Bluetooth antennas, and Beidou satellite antennas.

[0017] 3. A low-power design is adopted. All functional modules have power control functions. The main control chip uses a low-power microcontroller. In the non-working state, the controller is in the sleep state, and other modules are in the power-off state.

[0018] 4. The solar panel adopts an inclined design. On the premise of meeting the specifications of rainfall observation instruments, the solar panel is inclined to the maximum extent to receive light to the greatest extent.

[0019] 5. The Beidou satellite antenna is inclined and installed below the solar panel. There is a certain distance between its upper edge and the lower edge of the solar panel, and it faces the satellite, that is, the equator direction. This not only reduces the absorption of Beidou signals by the solar panel but also maximizes the power of the solar panel, effectively balancing the Beidou signal strength and the power of the solar panel.

[0025] The following further clarifies the present invention in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0026] As shown in the figure, the present invention provides an integrated dual-channel low-power rain gauge, which includes a rain gauge cylinder and an integrated control box arranged on the side of the rain gauge cylinder. The integrated control box includes a front panel 2 and a rear shell 8 arranged front and back. The panel is inclined. On the upper section of its surface, there is a solar panel 1. After leaving a certain distance from the solar panel 1, the lower section protrudes forward and internally has an inclined Beidou satellite antenna 3. Between the panel 2 and the rear shell 8, there are installed a Beidou satellite antenna fixing bracket 4, a circuit main board 5, a lithium battery 6 and an aviation plug 7. The Beidou satellite antenna fixing bracket 4 is used to install and support the Beidou satellite antenna 3. The circuit main board 5 includes a low-power microcontroller, a 4G / 5G module, a Beidou communication module, a Beidou positioning module, a switch input interface, a Bluetooth module, a USB interface and a charging control module. The lithium battery 6 is used for power supply. There are two aviation plugs 7, which are placed under the inner side of the rear shell 8.

[0027] In this embodiment, the 4G / 5G module is the main channel, and the Beidou communication module is the backup channel. The data transmission adopts a dual-channel working mode. In the normal mode, the 4G / 5G communication is preferentially used. When the 4G / 5G communication fails, the Beidou communication is enabled. It can also be directly set to use the Beidou communication. The dual-channel mode can be used in places where some network signals cannot cover, or in extreme environmental conditions such as natural disasters that cause network signal interruption.

[0028] In this embodiment, both the Beidou communication module and the Beidou positioning module are connected to the Beidou satellite antenna 3. This antenna supports the Beidou short message communication and positioning functions.

[0029] In this embodiment, the switch input interface can be connected to a single-layer tipping bucket device and a double-layer tipping bucket device. The single-layer tipping bucket has a simple structure, is reliable, has good stability, is convenient to maintain and easy to use. However, when used for small resolution, the accuracy is affected. The double-tipping bucket rain sensor is divided into upper and lower layers. The upper layer is a transition tipping bucket, and the lower layer is a measuring tipping bucket. The double tipping bucket can improve the accuracy of rain measurement. There are individual products used for tipping bucket rain gauges with a resolution of 0.1 mm, but the structure is complex and the reliability and stability are poor.

[0030] In this embodiment, the Bluetooth module and the USB interface are used to communicate with a remote terminal, including configuring parameters, sending instructions, viewing data, software upgrading, etc. Among them, the Bluetooth module is configured through the mobile phone side, and the USB interface is configured through the PC side. The configured parameters include station number, transmission protocol, rain gauge accuracy, rain threshold, acquisition interval, storage interval, sending interval, transport layer protocol, IP address or domain name, and network port. Among them, the transmission protocols include ASCII for hydrological monitoring data communication protocol, HEX for hydrological monitoring data communication protocol, water resource transmission protocol, etc.; and it can send instructions to the device to restart, reset parameters, clear storage, set time, acquire once immediately, and acquire and send. In addition, it also has a remote parameter configuration function. In addition to locally configuring the above parameters using USB and Bluetooth, the parameters can also be configured through 4G / 5G, and the relevant parameters are configured through the server of the central station.

[0031] In this embodiment, the charging control module is used to control the charging of the lithium battery 6.

[0032] In this embodiment, the lithium battery 6 is composed of 25 single 18650 lithium batteries with a single capacity of 3.7V and 3000mAh, and the total capacity is 75Ah. A large-capacity battery design is adopted.

[0033] In this embodiment, the aviation plug 7 is a four-core waterproof plug. One is connected to the tipping bucket device, and the other is reserved for backup. It can be externally connected to a solar panel, a battery, and other devices.

[0034] In this embodiment, an electronic level is also built in, which is used to report an alarm signal when the instrument is tilted to notify the maintenance personnel that the device needs maintenance. This can reduce the number of regular inspections and reduce the work intensity of the maintenance personnel.

[0035] The rain data acquisition of this application is carried out in an interrupt manner. Under normal circumstances, the system is in a sleep state to reduce power consumption. When there is a rain signal, a digital input signal will be introduced into the system to wake up the system and enter the working state, and at the same time process the rain signal. At this time, the acquisition work is completed.

[0036] Among them, there are two ways of data transmission. The first is the rainfall increment report, which needs to be judged according to the values of two parameters, namely the rainfall gauge accuracy and the rainfall threshold. If they are the same, the data will be sent immediately after the acquisition is completed; if they are different, it is necessary to count according to the rainfall gauge accuracy. When the count value accumulates to the rainfall threshold, the data will be sent. For example, if the rainfall gauge accuracy is 0.1 and the rainfall threshold is 1, the rainfall value will be counted ten times and then the data will be sent. The second is the regular report. The system reads the clock time in real time as the system time, and the current time can be set using a mobile phone or a PC; the microcontroller will set the alarm according to the acquisition interval, transmission interval, and storage interval of the configuration parameters. The alarm will send a wake-up level signal to the system according to the next wake-up time. After the system wakes up, it will first complete the acquisition and then send the data. When collecting the regular report, the data of the Beidou positioning module will be collected, the current longitude and latitude of the device will be read, and whether to send the positioning data will be determined according to the set parameters.

[0037] In this embodiment, for data transmission, the data is first packed according to the transmission protocol. After that, the 4G / 5G module is started, the power of the 4G / 5G module is turned on, the 4G / 5G module is initialized, and the packed data is sent to the specified server according to the IP address and port number. After the sending is successful, wait for the receipt. After receiving the receipt, turn off the power of the 4G / 5G module, and the system enters the sleep mode. If the initialization of the 4G / 5G module fails, the network cannot be connected, or no receipt is received after sending three times, the Beidou communication module will be started, the Beidou communication module will be initialized, and wait for the Beidou communication module to search for satellites. After completion, the packed data will be sent to the specified receiver according to the set satellite center number.

[0038] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
