Description

Technical Field

[0001] The utility model relates to the field of lightning early warning devices, and in particular to a split-type visual lightning early warning device. Background Art

[0002] Lightning is a common natural phenomenon, with extremely high electric field strength and current. It poses numerous hazards to human society and the natural environment, including damage to power facilities, interference with air traffic, and impacts on agricultural production. Therefore, predicting the time and location of lightning strikes is crucial for preventing lightning disasters.

[0003] Existing lightning warning systems usually integrate the interactive control host and the equipment for collecting atmospheric environment information on the same support column. The overall structure of the system is bulky, and there are problems such as insufficient flexibility during installation and use and poor maintainability. At the same time, since the host is fixedly installed on the equipment for collecting atmospheric environment information, when operators operate the various devices in the lightning warning system, they need to reach the installation location of the lightning warning system, and cannot perform data interaction locally. Utility Model Content

[0004] The purpose of this utility model is to provide a split-type visual lightning warning device to solve the problems of the existing lightning warning system, such as the large overall structure, insufficient flexibility during installation and use, poor maintainability, and inability to perform local data interaction.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A split-type visual lightning warning device comprises a host end for interaction and a collection end for acquiring data, wherein the host end and the collection end are connected via a first communication unit.

[0007] The existing lightning warning system has a problem of large overall structure and inability to interact with data locally. The utility model provides a split-type visual lightning warning device, which reduces the degree of coupling of system functional modules compared to traditional lightning warning systems by adopting a method of splitting the host for interactive control and the equipment for collecting information. While reducing the volume of the system structure, the system has a small installation footprint and more flexible location selection during installation and layout. The host end for data interaction can be set at any location according to actual needs, which improves the flexibility and maintainability of the lightning warning device during installation and use. In addition, the collected data can be operated locally without having to go to the device in an outdoor field environment, reducing the operating burden of the operator.

[0008] Furthermore, the host end includes a housing and a logic processing unit, a data storage unit and a display operation unit built into the housing. The data storage unit and the display operation unit are both connected to the logic processing unit, and the logic processing unit is provided with a first interface connected to the first communication unit.

[0009] Different equipment operating environments have different requirements for the functions of the lightning warning system. By designing the host to be controlled based on a logic processing unit and providing multiple interfaces, the functional modules can be adapted according to actual needs, reducing the functional coupling of the device and making the host more expandable while ensuring a streamlined structure.

[0010] Furthermore, the acquisition end includes a support and a sensor provided on the support, the support is provided with a second interface, and the sensor is connected to the first communication unit via the second interface.

[0011] By configuring the acquisition end to include only sensors and supporting fixed components and transmitting data through a communication unit, the structure of the lightning warning system can be streamlined.

[0012] Furthermore, the host end also includes a second communication unit connected to the logic processing unit and used to connect to a third-party device.

[0013] By setting up a second communication unit on the host side to connect with third-party equipment, the flexibility of data query and equipment control of the lightning warning device is further improved.

[0014] Furthermore, the first communication unit is provided with a first protection circuit, a second protection circuit and a third protection circuit connected in sequence, the first protection circuit is connected to a gas discharge tube, the second protection circuit is connected to a resettable fuse, and the third protection circuit is connected to a transient voltage suppression tube.

[0015] In addition to protective design of the lines themselves, data transmission in the lightning warning system also requires preventive protection against the impact of external lightning. By setting up a three-level protection circuit, preventive protection against external lightning shocks, current overload faults, and circuit electrostatic shocks can be achieved to ensure the safety of the lightning warning system itself and the effectiveness and accuracy of data transmission.

[0016] Furthermore, the communication mode of the first communication unit adopts a serial communication protocol.

[0017] Data is transmitted between the data acquisition device and the remote host by adopting the serial communication protocol. Compared with communication modes based on Ethernet and 4G / 5G, serial communication is more stable and has strong anti-interference ability, and is more suitable for the use scenarios of lightning warning devices.

[0018] Furthermore, the logic processing unit is also connected to an audible and visual alarm unit.

[0019] By connecting an audible and visual alarm unit to the host, the warning function of the lightning warning system in the device can be enhanced.

[0020] Furthermore, the support member is fixedly connected to a lightning rod, and there is a gap between the lightning rod and the sensor.

[0021] Since the sensor for data collection is set on a rod-shaped support with a certain height, it is easily affected by lightning strikes during thunderstorms. By fixing a lightning rod on the support at a certain distance from the sensor, the device itself has a lightning protection function to prevent damage to the sensor caused by lightning.

[0022] Furthermore, the logic processing unit is a microcontroller, the logic processing unit is connected to the second communication unit via a reduced media independent interface, and the data storage unit is a flash memory chip.

[0023] By using a microcontroller as the logic processing unit and a simplified media independent interface as the interface for connecting to the second communication unit, the host-side structure is made more streamlined by utilizing the small structure of the component body. At the same time, the functions integrated in the microcontroller itself meet the host control requirements, and the microcontroller is provided with a variety of types of interfaces, which improves the scalability of the device. In addition, a flash memory chip is used as the data storage unit, which has a compact and exquisite structure and occupies a small space, which can further reduce the volume of the host-side structure.

[0024] Furthermore, the support member is fixedly provided with a plurality of sensor reserved interfaces connected to the second interface.

[0025] By reserving sensor interfaces instead of directly installing multiple sensors on the acquisition end during installation, the overall structure and volume of the acquisition end can be simplified, and the installation difficulty and workload can be reduced. At the same time, additional sensors can be installed later according to actual needs, thereby improving the functional expandability of the acquisition end.

[0026] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0027] (1) The utility model provides a split-type visual lightning warning device. By adopting a method of splitting the host for interactive control and the equipment for collecting information, compared with the traditional lightning warning system, the degree of coupling of the system functional modules is reduced, the system structure volume is reduced, and the installation footprint of the system is small during installation and layout, and the location selection is more flexible. In addition, the host end for data interaction can be set at any location according to actual needs, thereby improving the flexibility and maintainability of the lightning warning device during installation and use. In addition, data operations can be performed locally without having to go to the device located in an outdoor field environment, thereby reducing the operating burden of the operator.

[0028] (2) The utility model provides a split-type visual lightning warning device, which realizes preventive protection against external lightning shocks, current overload faults, and circuit electrostatic shocks by setting a three-level protection circuit, so as to ensure the safety of the lightning warning system device itself and the effectiveness and accuracy of data transmission.

[0029] (3) The utility model provides a split-type visual lightning warning device. By adopting a design based on a microcontroller as a logic processing unit and relying on the microcontroller's external functional modules, the host side structure is made more streamlined by taking advantage of the microcontroller's own small structure and high integration. A simplified media independent interface is used as the interface for connecting to the second communication unit and a flash memory chip is used as the data storage unit to further reduce the structural volume of the host side device. At the same time, the acquisition side adopts a method of reserving sensor interfaces instead of directly installing multiple sensors on the acquisition side during installation, making the overall structural volume of the acquisition side smaller. Lightweight structural designs are adopted on both the host side and the acquisition side to reduce the weight and volume of the lightning warning device, thereby reducing the workload and difficulty required for installation, making the equipment more convenient during transportation and handling.

[0039] Please refer to Figure 1-Figure 4 An embodiment of the present invention provides a split-type visual lightning warning device, comprising a host terminal 1 and a collection terminal 2. The collection terminal 2 is used to obtain environmental data in the atmosphere in real time, such as electric field strength, magnetic field changes, etc., to determine the possibility of lightning activity. Figure 2As shown, the acquisition end 2 includes a sensor 202 and a support 201 for supporting and fixing the sensor 202. The support 201 is fixed to the ground through a base 204 provided at the bottom. The base 204 is provided with a second interface 208 for connecting to the first communication unit. In order to reduce the damage caused by the sensor 202 being struck by lightning, a lightning rod 203 is also fixed on the support 201. A certain distance is maintained between the lightning rod 203 and the sensor 202, and an independent lightning protection down conductor is provided to ensure that the lightning rod 203 will not conduct lightning to the space area where the sensor 202 is located while protecting the lightning. On the sensor 202, the sensor 202 can be an atmospheric electric field sensor or an atmospheric electromagnetic sensor. The host end 1 and the acquisition end 2 are split into a design, that is, the host end 1 and the acquisition end 2 are two relatively independent parts. The acquisition end 2 is set in the corresponding area according to needs, and the host end 1 is set at a designated location according to actual needs. The two are based on the connection of the first communication unit to carry out data transmission. The host for interactive control and the equipment for collecting information are set separately. Compared with the traditional lightning warning system, the coupling degree of the system functional modules is reduced, while reducing the system structure volume and making the system installation layout more flexible. In addition, data operations can be performed locally without having to reach the device set in the outdoor field environment, reducing the operating burden of the operator. Among them, the host end 1 can be a conventional electronic device with data transmission and display functions. The communication protocol adopted by the first communication unit can be Ethernet, 4G / 5G communication protocol or serial communication protocol. As a preferred solution, the communication protocol adopted by the first communication unit is a serial communication protocol. The host end 1 and the acquisition end 2 are respectively provided with a first interface 105 and a second interface 208. The control unit in the host end 1 is connected to the acquisition end through a communication cable. 2 is connected to the sensor 202 and data transmission is realized. The first interface 105 and the second interface 208 can be an RS232 serial interface or an RS485 serial interface. In the same set of devices, the serial interfaces of the host terminal 1 and the acquisition terminal 2 are consistent. The support member 201 of the acquisition terminal 1 is fixed with a sensor reserved interface 206. By adopting the method of reserving sensor interfaces instead of directly installing multiple sensors on the acquisition terminal 1 during installation, the overall structural volume of the acquisition terminal 1 can be simplified, and the installation difficulty and workload can be reduced. At the same time, sensors can be installed according to actual needs in the future, thereby improving the functional expandability of the acquisition terminal.

[0040] The host end 1 includes a housing 101, a power supply interface 104 for supplying power to the host end 1, and a first interface 105 for connecting to the first communication unit. A wall-mounted locking structure 106 is fixed on the back of the housing 101. 106 is used to fix the housing 101 on the wall. The wall-mounted locking structure 106 and the wall can be connected by bolts or hooks. The host end 1 is provided with a second communication unit, which includes a second communication unit first sub-interface 108 and a second communication unit second sub-interface 110. The second communication unit first sub-interface 108 can be a 4G antenna SMA interface and a 5G antenna The host terminal is provided with an external storage interface 109 for exporting the internal data of the host terminal 1 or mounting a program. The external storage interface 109 can be a USB interface or an SD card data interface. The host terminal 1 is also provided with a leakage protection switch 107 to ensure the safe operation of the internal module. The main functional units built into the housing 101 include a logic processing unit, a data storage unit and a display operation unit. The data storage unit and the display operation unit are both connected to the logic processing unit. The logic processing unit is provided with an interface connected to the first communication unit. The interface can It is an RS232 serial interface or an RS485 serial interface. As a preferred solution, a microcontroller is used as the controller of the logic processing unit. The functions integrated in the microcontroller itself can meet the control requirements of the host end 1. In addition, the use of the microcontroller makes the structure of the host end 1 lightweight. At the same time, the microcontroller is provided with various types of interfaces, which can also improve the scalability of the device. The model of the microcontroller can be STM32 series or STM8 series. The data storage unit can be a hard disk or a flash memory. As a preferred solution, a flash memory chip is used as the data storage unit, wherein the number of flash memory chips used as the data storage unit can be multiple chips and Reusing the same SPI bus, the flash memory chip has a relatively small and exquisite structure, occupies a small space, and thus the host-side structure is more lightweight. The display operation unit can be a conventional LCD screen or a touch screen. In addition, the host end 1 also includes a second communication unit connected to the logic processing unit and used to connect to a third-party device. The communication protocol of the second communication unit can adopt Ethernet, 4G or 5G communication protocol. The third-party device can be a mobile electronic device or a desktop computer. By setting a second communication unit on the host side to connect to the third-party device, the flexibility of data query and device control of the lightning warning device is further improved. The logic processing unit can also be connected to an external sound and light alarm unit. The sound and light alarm unit is an existing alarm device with sound and light alarm function and can be connected to a microcontroller to enhance the prompt function of the lightning warning device.

[0041] Exemplarily, the logic processing unit adopts an STM32F207VC microcontroller, which has multiple hardware peripheral interfaces such as RMII, UART, SPI, I2C, USB FS, etc., reducing the need to add additional electronic chips to meet circuit functions. The data storage unit adopts two W25Q128 Nor Flash chips as extended storage, reuses the same SPI bus to be connected to the main control chip, and realizes separate control of the two Flash chips through two chip select interfaces; for the first sub-interface of the second communication unit, a 4G Cat.1 module is selected, which has low cost and low power consumption, and is connected to the main control chip using a serial communication interface. For the second sub-interface of the second communication unit, a LAN8720A low-power 10 / 100Mbps physical layer transceiver is selected, and a precise independent interface is used to connect to the main control chip. The clock signal adopts the clock signal output of the main control chip, and the transceiver port adopts the RJ45 interface with its own network transformer, thereby making the circuit design of the host end 1 more streamlined, occupying less circuit board space, and further reducing costs. Furthermore, because the main control chip's built-in real-time clock has significant errors, this device uses an external DS3231M high-precision clock, which can maintain an error of ±0.432 seconds per day. This chip is connected to the main control chip via an I2C interface. The display and operation unit uses a 10.1-inch industrial-grade capacitive touchscreen, connected to the logic processing unit via a standard RS232 serial communication interface. Furthermore, the SP3232EEN chip is used for interface level conversion, which is low-cost and compatible with 3.3V TTL levels.

[0042] In addition to protective design for the lines themselves, data transmission in the lightning warning system also requires preventive protection against the impact of external lightning to ensure the safety of the lightning warning system device itself and the effectiveness and accuracy of data transmission. The first communication unit is provided with a first protection circuit, a second protection circuit, and a third protection circuit connected in sequence. The first protection circuit is connected to a gas discharge tube, the second protection circuit is connected to a resettable fuse, and the third protection circuit is connected to a transient voltage suppressor.
