Description

Technical Field

[0001] This utility model relates to the field of gas leak detection, specifically to a dual-power supply equipment operation status monitoring device and a gas leak early warning monitoring terminal device. Background Technology

[0002] In the oil and gas sector, methane leaks in industrial plants or pipelines not only directly cause energy waste and economic losses, but also pose a series of hazards to the environment, safety, and business operations. Methane is a flammable and explosive gas; when it accumulates to a certain concentration in the environment, it can easily cause fires, explosions, and other safety accidents, threatening human lives and facility safety. Simultaneously, methane leaks directly lead to local environmental pollution, posing a potential threat to surrounding ecosystems and residents' health. Therefore, leak early warning and monitoring terminal equipment has already been deployed at key points in industrial plants and pipelines.

[0003] However, traditional leak detection and early warning terminal equipment generally uses two types of power supplies: the first is solar power, which is environmentally friendly and can operate continuously for a long time as long as sunlight intensity is guaranteed; the disadvantage is that the power generation efficiency of the photovoltaic panels will decrease in cloudy or rainy weather, winter when sunlight is scarce, as well as in high temperatures and thunderstorms. The second type uses disposable lithium batteries, which has the advantages of high energy density and good climate resistance; the disadvantage is that it does not have recharging capability and the cost of battery replacement is high. Now, some companies have proposed dual-power supply solutions for gas leak detection. For example, CN215112069U discloses a method of switching between external atmospheric pressure power and solar power to achieve long-term monitoring of gas leaks.

[0004] However, considering that solar-powered energy storage batteries are generally lead-acid or rechargeable lithium batteries, their discharge capacity decreases and charging efficiency drops sharply as temperature decreases. For example, with lead-acid batteries, the range decreases by about 2% for every degree Celsius drop below 0°C. When the temperature drops to -20°C, the discharge capacity of lead-acid batteries is reduced to only about 40% of the total capacity, and even lower for batteries that are not brand new. Therefore, in low-temperature environments, dual power sources should be switched to disposable lithium batteries. Since the energy supplied by disposable lithium batteries is limited, it is necessary to minimize the number of times and duration of power supply from disposable lithium batteries in non-low-temperature environments; that is, in non-low-temperature environments, solar power should be used as much as possible.

[0005] Furthermore, in practical applications, leakage early warning monitoring terminal equipment is usually installed in outdoor environments. Due to the complex factors of the outdoor environment, solar power supply may encounter various problems. For example, excessive dust accumulation on the surface of the solar photovoltaic panels and strong winds can cause the solar photovoltaic panels to tilt or even fall over, all of which can affect the power supply from the solar power source. Therefore, it is necessary to monitor the status of the solar photovoltaic panels in the dual-power supply equipment in a timely manner to ensure that the solar power supply conditions are met; and to switch to solar power supply mode in a timely manner when the solar power supply conditions are met.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1

[0031] like Figure 1 and 2 As shown, this embodiment provides a dual-power supply equipment operation status monitoring device. The dual-power supply equipment includes a disposable lithium battery power supply unit, a solar power supply unit, and a power switching execution unit. The solar power supply unit includes a solar photovoltaic panel 1 and an energy storage battery.

[0032] The dual-power supply equipment operation status monitoring device includes a main control board, a temperature sensor, an ambient temperature and humidity sensor 2, a first illuminance sensor 3, a second illuminance sensor 4, an attitude sensor 5, and a first battery voltage detection circuit. In one possible embodiment, the attitude sensor 5 is a T0100 high-precision single / dual-axis tilt sensor from Jiaxing Najie Microelectronics Technology Co., Ltd.; the temperature sensor is a PT100 temperature sensor; and the ambient temperature and humidity sensor is a ZS0301 temperature and humidity module from Zhengzhou Weisheng Electronics Technology Co., Ltd.

[0033] The main control board includes a main controller and a communication transmission unit, such as... Figure 2 As shown, in one embodiment, the communication transmission unit is preferably an EC801E wireless module, and the main controller is an ATXMEGA16A4-MH.

[0034] Both the first illuminance sensor 3 and the second illuminance sensor 4 are SM9560B type illuminance sensors from Shanghai Soobo Industrial Co., Ltd.

[0035] Specifically, such as Figure 2 As shown, the first illuminance sensor 3, the second illuminance sensor 4, and the attitude sensor 5 are all connected to the main control board via the 485 bus communication interface U3.

[0036] Specifically, such as Figure 2 As shown, the power switching execution unit includes a first switching circuit composed of power transistors P1 and N3, and a second switching circuit composed of power transistors P2 and N4. When power is required from the solar power unit, the main controller control pin Pw_V_SE goes low, and the power transistors N4 and P2 of the second switching circuit are turned on, allowing the energy storage battery to supply power to the device directly. When power is required from the solar power unit, the main controller control pin Pw_V_BAT goes low, and the power transistors N3 and P1 of the first switching circuit are turned on, allowing the disposable lithium battery to supply power to the device directly.

[0037] The first battery voltage detection circuit consists of a power transistor N2 and resistors R7, R8, R9 and R10; a detection signal output pin SE_AD is provided between resistors R7 and R8 to connect to the main controller; when the Chk_SE pin controlled by the main controller is low, the power transistor N2 is turned on, and the voltage of the energy storage battery is detected through the detection signal output pin SE_AD.

[0038] In practical use, the PT100 temperature sensor is installed on the surface of the energy storage battery to detect the surface temperature of the battery.

[0039] The first illuminance sensor 3 is installed on the upper surface of the solar photovoltaic panel 1 to detect the natural light intensity on the upper surface of the solar photovoltaic panel 1; the second illuminance sensor is installed on the lower surface of the solar photovoltaic panel to detect the natural light intensity on the lower surface of the solar photovoltaic panel.

[0040] The ambient temperature and humidity sensor is installed on the lower surface of the solar photovoltaic panel 1 and is used to detect ambient temperature and humidity.

[0041] The attitude sensor 5 is installed on the lower surface of the solar photovoltaic panel 1 and is used to detect the attitude of the solar photovoltaic panel 1.

[0042] The first battery voltage detection circuit is connected to the energy storage battery and is used to collect the battery voltage of the energy storage battery;

[0043] The main control board is connected to the temperature sensor, the first illuminance sensor 3, the second illuminance sensor 4, the ambient temperature and humidity sensor 2, the attitude sensor 5, and the first battery voltage detection circuit, respectively, and is used to collect the detection signals output by the temperature sensor, the first illuminance sensor 3, the second illuminance sensor 4, the ambient temperature and humidity sensor 2, the attitude sensor 5, and the first battery voltage detection circuit, and to upload the collected detection signals to the monitoring terminal through the communication transmission unit;

[0044] The main control board also receives power switching commands from the monitoring terminal through the communication transmission unit and triggers the power switching execution unit to perform power switching.

[0045] The monitoring terminal can be an edge gateway or a cloud monitoring server.

[0046] In this embodiment, taking the edge gateway as an example, in the initial state, the dual power supply equipment uses a solar power supply unit as the direct power supply to supply power to the device.

[0047] The first battery voltage detection circuit detects the battery voltage (V1) of the energy storage battery and uploads the detection result to the edge gateway. When the edge gateway determines that the battery voltage (V1) of the energy storage battery is less than or equal to the preset energy storage battery discharge voltage alarm threshold (VL1), it generates a switching command so that the power switching unit of the dual power supply device can switch the primary lithium battery power supply system to the direct power supply.

[0048] When the primary lithium battery power supply system is used as the direct power supply, when the edge gateway determines that the battery voltage (V1) of the energy storage battery is greater than or equal to the preset energy storage battery charging voltage threshold (VH1), it generates a switching command so that the power switching unit of the dual power supply equipment can switch the solar power supply system to the direct power supply.

[0049] The above switching strategy can ensure that the usage time and number of times the disposable lithium battery power supply system is minimized without interrupting power.

[0050] It is understandable that in scenarios where a solar power unit is used as a direct power source to supply power to the device, the ambient temperature and humidity sensor 2 also detects the ambient temperature and humidity and uploads the detection results to the edge gateway.

[0051] When the edge gateway determines that the received ambient temperature is less than or equal to a set temperature threshold, such as -10°C, it generates a switching command so that the power switching unit of the dual power supply device can directly switch the disposable lithium battery power supply system to the device's direct power supply.

[0052] When the edge gateway determines that the ambient humidity is above 80%RH for an extended period (e.g., 24 consecutive hours), it identifies the weather at the installation location as cloudy or rainy and raises the energy storage battery discharge voltage alarm threshold, for example, by setting a preset energy storage battery discharge voltage alarm threshold (VL1) + 0.1V. At this point, it continues to assess the relationship between the energy storage battery voltage (V1) and the energy storage battery discharge voltage alarm threshold (VL1) + 0.1V. When the energy storage battery voltage (V1) is less than or equal to the raised energy storage battery discharge voltage alarm threshold (VL1) + 0.1V, it generates a switching command so that the power switching unit of the dual-power supply equipment can directly switch the primary lithium battery power supply system to the device's direct power supply. Simultaneously, it alerts management personnel to the charging efficiency of the solar power system.

[0053] Under normal circumstances, the air humidity is 40%RH~70%RH; during cloudy and rainy weather, the air humidity is 80%RH~90%RH, or even as high as 95%RH. It is understandable that during continuous cloudy and rainy weather, charging efficiency is low. At this time, by increasing the discharge voltage alarm threshold of the energy storage battery, abnormal charging caused by self-discharge of the energy storage battery can be avoided.

[0054] Under normal circumstances, the light intensity on the upper surface of the solar photovoltaic panel 1 should be greater than that on the lower surface; otherwise, the upper surface might be covered by dust or other debris. In this embodiment, the first illuminance sensor 3 and the second illuminance sensor 4 collect and upload the illuminance data from the upper and lower surfaces of the solar photovoltaic panel 1. When the edge gateway determines that the illuminance (Lx1) on the upper surface collected by the first illuminance sensor 3 is significantly less than the illuminance (Lx2) on the lower surface collected by the second illuminance sensor 4 (assuming Lx1 is less than or equal to 2*Lx2), it generates a cleaning warning (the solar photovoltaic panel may need cleaning), reminding management personnel to perform maintenance to restore the charging capacity of the solar photovoltaic panel 1 as soon as possible.

[0055] In addition, under normal circumstances, the tilt angle of the solar photovoltaic panel 1 is fixed, specifically facing the direction with the highest solar energy reception efficiency within a day. When affected by strong winds or human damage, the tilt angle of the solar photovoltaic panel 1 may change, thereby affecting the charging capacity of the solar photovoltaic panel 1. Therefore, in this embodiment, a T0100A high-precision single and dual-axis tilt sensor is used as the attitude sensor 5 to collect the tilt angle of the solar photovoltaic panel 1 and upload it to the edge gateway. When the edge gateway determines that the difference between the tilt angle of the solar photovoltaic panel 1 and the preset angle threshold is greater than or equal to the alarm threshold, it generates a tilt and collapse warning message (the difference is greater than or equal to the alarm threshold, which means that the solar photovoltaic panel 1 may have tilted or even collapsed), reminding the management personnel to perform maintenance in order to restore the charging capacity of the solar photovoltaic panel 1 as soon as possible.

[0056] In addition, when the direct power supply of the dual power supply equipment is a disposable lithium battery power supply system, and the edge gateway detects that the battery voltage of the solar power supply system's energy storage battery has not increased for a long time (e.g., 7 days) (i.e., it has failed to charge), it is considered that there is a fault in the solar power supply system, and a fault warning message needs to be generated to remind the management personnel to perform maintenance.

[0057] Furthermore, this embodiment also includes a second battery voltage detection circuit, which is connected to the disposable lithium battery power supply unit and used to collect the battery voltage of the disposable lithium battery power supply unit and upload it to the edge gateway. When the edge gateway determines that the battery voltage (V2) of the disposable lithium battery power supply system is less than or equal to the voltage alarm lower limit (VL2) of the disposable lithium battery, it needs to generate a lithium battery replacement warning message to remind the management personnel to perform maintenance (replace the disposable lithium battery).

[0058] like Figure 2 As shown, the second battery voltage detection circuit consists of a power transistor N1 and resistors R3, R4, R5 and R6; a detection signal output pin Bat_AD is provided between resistors R3 and R4 to connect to the main controller; when the Chk_Bat pin controlled by the main controller is low, the power transistor N1 is turned on, and the voltage of the disposable lithium battery is detected through the detection signal output pin SE_Bat.

[0068] Specifically, the working principle of the dual power supply equipment operation status monitoring device is described in Example 1, and will not be detailed here.

[0069] In one possible embodiment, the control module and the main controller in the dual-power supply equipment operation status monitoring device are the same control unit, as can be seen from [reference needed]. Figure 3 and Figure 4 Of course, the control module can also be a different control unit from the main controller in the dual-power supply equipment operation status monitoring device.

[0070] like Figure 4 As shown, the vibration sensor, the first illuminance sensor 3, the second illuminance sensor 4, and the attitude sensor 5 are all connected to the main control board via a 485 bus communication interface U3.

[0071] The gas sensor, the image sensor, and the communication transmission unit are connected to the main control board via a 74HC4052 analog switch circuit for communication.

[0072] The gas sensor is connected to the control module and is used to detect the concentration of the target gas at the monitoring point in real time and store it in the control module.

[0073] The image sensor is connected to the control module and is used to capture images / videos of the detection point in real time and store them in the control module.

[0074] The wind speed and direction sensor is connected to the control module and is used to detect the environmental wind speed and direction at the monitoring point in real time and store the data in the control module.

[0077] It is understandable that gas leak early warning and monitoring terminal equipment generally operates intermittently, that is, it periodically collects the target gas concentration, on-site images / videos of the detection point, the location of the detection terminal, vibration information, ambient wind speed and direction, and ambient temperature and humidity, and periodically uploads the target gas concentration, on-site images / videos of the detection point, the location of the detection terminal, vibration information, ambient wind speed and direction, and ambient temperature and humidity, and is in a low-power standby state when not collecting / uploading data, so as to minimize the overall power consumption of the device.
