Description

TECHNICAL FIELD

[0001] The utility model relates to laser radar technical field, especially a kind of laser radar state acquisition device. BACKGROUND

[0002] With the rapid development of global meteorology and environmental protection field, laser radar as an important detection tool, has been widely applied in atmospheric environment monitoring.Laser radar utilizes laser beam to carry out accurate measurement and detection to target object, has the advantages such as long detection distance, wide coverage, high detection precision etc.In meteorological industry, laser radar is often used for atmospheric composition detection, atmospheric wind field detection, cloud height monitoring, aerosol and pollutant concentration monitoring etc., becomes important tool of fine meteorological observation.And in environmental protection field, laser radar is also widely used in pollutant monitoring and atmospheric environmental quality assessment.With the expansion of these application fields, laser radar has gradually become the key equipment of urban air quality monitoring and regional environmental assessment.

[0003] The high-precision detection capability of laser radar depends on its complex optical and electronic system, including laser, photomultiplier tube, data acquisition card and other core components, which have very high requirements for working environment.In practical application, laser radar is usually installed in urban area, suburban area or even multiple locations across cities to realize wide-range meteorological monitoring and environmental protection detection.Because the deployment points of laser radar are usually located in wide area, and the equipment needs to work continuously for a long time, the operation and maintenance work faces great challenges.Firstly, the detection equipment of laser radar is widely distributed, and the daily inspection and fault maintenance of operation and maintenance personnel need to be carried out across regions, which undoubtedly increases the workload of operation and maintenance.Secondly, laser radar system has high professionalism, once fault occurs, non-professional personnel is difficult to quickly locate and solve the problem, which requires operation and maintenance personnel not only to have deep technical knowledge, but also to have strong on-site problem analysis ability.In addition, laser radar users often move the position of equipment arrangement due to the need of monitoring task during use, and the complexity of operation and management is further improved.The change of equipment position puts forward higher requirements for operation and management, and the movement of equipment means that the environment around the equipment, network connection state etc.are also changed, which increases the uncertainty and complexity of remote monitoring and operation and maintenance of laser radar.

[0004] To ensure the stable operation of the LiDAR system, the current operation and maintenance management model relies on operators remotely connecting to the LiDAR's computer system to monitor the device's status in real time and diagnose faults. Technicians can remotely access the computer to obtain the LiDAR's operating parameters, data collection status, and environmental monitoring data. However, if the computer system fails due to a network outage or system crash, operators will be unable to remotely access the device, resulting in an unavailable LiDAR status information. Troubleshooting the device must be performed through on-site maintenance. This not only significantly increases device downtime but also makes it impossible to accurately trace the root cause of the problem due to the loss of logs and data, significantly inconvenient for operation and maintenance management. Furthermore, traditional remote monitoring relies on the normal operation of the computer system, leaving the LiDAR with blind spots in the event of a network or power outage.

[0005] Therefore, how to collect and record the operating status of the equipment when the lidar system is disconnected from the network, power off or in other fault conditions, and transmit the fault information to the remote server through backup power or other communication methods has become a technical problem that needs to be solved urgently.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0029] like Figures 1 to 2 As shown, in order to achieve the above purpose, the present invention proposes a laser radar state acquisition device, comprising:

[0030] The central processing unit is connected to the radar industrial computer through the serial communication module to collect the operation data and status data of the radar industrial computer in real time; and

[0031] The Internet of Things communication unit is connected to the central processing unit and is used to send the operation data and status data collected by the central processing unit to the server.

[0032] Specifically, the central processing unit (CPU) is the core of the entire system, responsible for collecting and processing operational and status data from the radar's industrial computer. The CPU connects to the radar's industrial computer via a serial communication module, receiving data from the computer in real time. The serial communication module facilitates communication between the CPU and the radar's industrial computer, transmitting operational and status data from the computer to the CPU.

[0033] The IoT communication unit is responsible for sending the operational and status data collected by the central processing unit to the server for remote monitoring and maintenance. The server receives the radar industrial computer data from the IoT communication unit for subsequent status monitoring, fault analysis, remote management, and other operations.

[0034] Using this technical solution, the entire LiDAR system can be remotely monitored via the IoT communication unit, reducing the time and cost of on-site maintenance by operators. Furthermore, real-time data upload ensures transparency of device status and improves the accuracy and timeliness of monitoring. The central processing unit collects data from the industrial computer in real time via the serial communication module, effectively reducing the potential risks associated with undetected faults and ensuring efficient system operation. Even in the event of a power outage or network interruption, the IoT communication unit can continue to transmit data via backup communication methods, ensuring that the device remains monitorable. In the event of a device failure, operators can quickly locate the problem and remotely address it based on real-time data received from the server, reducing device downtime and maintenance costs.

[0035] In one embodiment of the present application, a positioning unit is further included, which is used to collect positioning data and send the collected positioning data to the central processing unit through the serial communication module.

[0036] Specifically, the positioning unit is used to collect the geographical location information of the device. The positioning unit obtains the device's location information such as longitude and latitude based on satellite positioning systems such as GPS and Beidou.

[0037] The positioning unit is connected to the central processing unit through a serial communication module, and the serial communication module is responsible for transmitting the collected positioning data to the central processing unit.

[0038] The positioning unit provides real-time device location information, making it particularly useful in scenarios where mobile LiDAR equipment is required. Equipment locations can change frequently, such as when LiDAR equipment is deployed across multiple locations in a city. Accurate location information helps operators quickly locate equipment for maintenance.

[0039] Using this technical solution, the positioning unit can provide precise location information, which not only facilitates remote monitoring of equipment locations but also helps operators quickly locate equipment when it fails or needs to be relocated. This can greatly improve operation and maintenance efficiency and reduce unnecessary time when managing multiple devices across multiple regions.

[0040] In one embodiment of the present application, a temperature sensor is further included for collecting temperature data and sending the collected temperature data to the central processing unit via the serial communication module.

[0041] Specifically, temperature sensors are used to collect ambient temperatures around or within the device. LiDAR equipment is highly sensitive to temperature during operation, and changes in ambient temperature can affect the stability of key components such as the laser and data acquisition card. Temperature sensors collect ambient temperature data in real time and transmit this data to the central processing unit via a serial communication module.

[0042] By adopting the above technical solution, the temperature sensor can ensure that the device operates within the appropriate temperature range, and detect and handle abnormal device temperature in a timely manner.

[0043] In one embodiment of the present application, a humidity sensor is further included for collecting humidity data and sending the collected humidity data to the central processing unit via a serial communication module.

[0044] Specifically, the temperature sensor is used to collect real-time temperature information of the device or its surrounding environment. The temperature sensor continuously monitors the temperature of the device environment and sends the temperature data in the form of a digital signal to the central processing unit via the serial communication module.

[0045] Using this technical solution, real-time temperature monitoring can prevent equipment failures caused by high or low temperatures. When the temperature exceeds a set range, the system can automatically take action, such as sounding an alarm, shutting down equipment, or even initiating cooling. This real-time feedback mechanism helps protect equipment, extend its lifespan, and reduce damage caused by temperature fluctuations.

[0046] In one embodiment of the present application, a battery pack is further included to provide power to the central processing unit.

[0047] Specifically, through the offline battery pack, when the mains power fails, the offline battery pack can be used to continue to supply power to ensure that it can continue to work.

[0048] In one embodiment of the present application, an indication unit is further included, which is connected to the central processing unit and is used to indicate the working status of the laser radar.

[0049] By adopting the above technical solution and setting up an indication unit, maintenance personnel can conveniently observe the working status of the laser radar.

[0050] In one embodiment of the present application, an Ethernet communication module is further included, connected to the central processing unit, for providing an Ethernet data transmission interface.

[0051] By adopting the above technical solution and setting up an Ethernet communication module, stable and high-speed data transmission can be achieved.

[0052] In one embodiment of the present application, the serial communication module includes:

[0053] transceiver, first EMI filter 11, second EMI filter 12, first transient suppression diode 21, second transient suppression diode 22;

[0054] The first end of the first EMI filter 11 is connected to the input end of the transceiver, and the second end of the first EMI filter 11 is connected to the third pin of the terminal; the first end of the second EMI filter 12 is connected to the output end of the transceiver, and the second end of the second EMI filter 12 is connected to the first pin of the terminal; the first end of the first transient suppression diode 21 is connected between the second end of the first EMI filter 11 and the third pin of the terminal; the first end of the second transient suppression diode 22 is connected between the second end of the second EMI filter 12 and the first pin of the terminal, the second end of the first transient suppression diode 21 is connected to the second end of the second transient suppression diode 22 and is grounded; and the second pin of the transceiver is grounded.

[0055] Specifically, the transceiver is responsible for sending and receiving data. The input end of the transceiver is connected to the first end of the first EMI filter 11 to form a signal input path. The output end of the transceiver is connected to the first end of the second EMI filter 12 to form a signal output path.

[0056] The first end of the first EMI filter 11 is connected to the input end of the transceiver for filtering electromagnetic interference (EMI) in the input signal. The second end of the first EMI filter 11 is connected to the third pin of the terminal, ie, the data input end.

[0057] The first end of the second EMI filter 12 is connected to the output end of the transceiver to filter electromagnetic interference (EMI) in the output signal. The second end of the second EMI filter 12 is connected to the first pin of the terminal, that is, the data output end.

[0058] A first end of a first TVS diode 21 is connected between the second end of the first EMI filter 11 and the third pin of the terminal, primarily for protecting the input line from transient voltage shocks. A second end of the first TVS diode 21 is connected to ground and is connected together with the second end of the second TVS diode 22.

[0059] A first end of a second TVS diode 22 is connected between the second end of the second EMI filter 12 and the first pin of the terminal, primarily for protecting the output line from transient voltages. A second end of the second TVS diode 22 is connected to ground and to the second end of the first TVS diode 21.

[0060] The above technical solution, through the first and second EMI filters 12, effectively filters electromagnetic interference (EMI) from input and output signals, improving the system's anti-interference capabilities and ensuring the integrity and stability of communication signals. The first and second TVS diodes 21 and 22 protect the input and output lines, respectively. In the event of a transient high voltage or surge, the diodes can instantly conduct, directing the overvoltage to ground, thereby preventing damage to sensitive components such as the transceiver and improving the module's overvoltage tolerance.

[0061] In one embodiment of the present application, the serial communication module further includes:

[0062] The first gas discharge tube 31 has a first end connected between the second end of the first EMI filter 11 and the third pin of the terminal, and a second end of the first gas discharge tube 31 is grounded.

[0063] Using this technical solution, the gas discharge tube (GDT) is a highly effective overvoltage protection device. When a high-energy transient overvoltage (such as a lightning strike or power spike) occurs, the GDT quickly breaks down and conducts, diverting the overvoltage through its second terminal to ground, thus preventing damage to the input terminals and subsequent circuitry.

[0064] In one embodiment of the present application, the serial communication module further includes:

[0065] The second gas discharge tube 32 has a first end connected between the second end of the second EMI filter 12 and the first pin of the terminal, and a second end of the second gas discharge tube 32 is grounded.

[0066] By adopting the above technical solution, the protection capability of the circuit is improved.

[0067] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, as described in the present application specification and drawings, is included in the patent protection scope of the present application.
