[0002] With the deepening of research on highway slope monitoring and disaster warning systems, more and more automated monitoring equipment has been put into use on slopes. Since there is no stable mains electricity on the slope, the monitoring equipment actually used is powered by solar energy. Therefore, the solar power supply system plays an important role in the power supply of the slope monitoring system. In order to ensure stable and sufficient power supply, the power supply parameter design and power supply status monitoring research of the solar power supply system are of great significance to the construction and stable operation of slope monitoring projects.

[0003] For the design of power supply parameters, the local daily sunshine time, the number of power supply days on rainy days, the working mode of the power supply equipment and the power consumption all affect the selection of solar panel parameters, battery parameters and controller parameters. At present, there are some parameter analyses for solar panels and batteries, but it is still necessary to optimize the solar energy system based on the following factors. First, the parameters in each working environment are different. For example, the working hours on rainy days in different places affect the design of battery capacity, the working hours of the equipment affect the actual power consumption of the equipment, and the local light time affects the actual power output of the solar panel. These parameters all affect the parameter design. Second, the equipment on the slope will take into account the energy saving of the equipment. The actual working mode is the sleep mode, that is, the working time of the equipment can be set by minutes, hours and other frequencies. The actual power consumption is related to the setting frequency. A parameter calculation method based on the sleep state is needed to ensure reasonable parameter selection.

[0004] Therefore, it is urgent to take into account more influencing factors in practice and more reasonably optimize the parameter design of the solar power supply system of highway slope monitoring equipment, so that designers can more reasonably choose the solar panel power, battery capacity and controller in the solar power supply system of highway slope monitoring equipment.

[0043] This embodiment provides a method for designing parameters of a solar power supply system for a slope monitoring device. Figure 1 The figure shows the power supply principle diagram of the solar energy system. The solar energy system is divided into three parts, namely, solar photovoltaic panels, controllers and batteries. Solar photovoltaic panels can convert light energy into electrical energy during the day, and store the electrical energy in batteries through controllers, and then supply DC loads. In the slope, the load is the relevant automatic monitoring equipment. The solar power supply system design of the monitoring equipment usually uses a single panel-single battery power supply method, but due to the extreme environment on the slope, such as weeds, mountains and dust on the surface of the solar panels, the light intensity of the power supply system is greatly weakened. The original power supply system cannot meet the current power supply needs, so sometimes it is necessary to install on the original system, considering the following: Figure 2 The dual-panel-dual-battery parallel power supply method shown in the figure can ensure the power supply demand of the equipment, but the parameters of the solar panel, controller and battery must be the same. At this time, the solar panel power and battery capacity are both twice that of the single-panel-single-battery power supply method, while the voltage remains unchanged. The main consideration of the solar power supply system is to meet the actual power supply demand of the monitoring equipment. In the calculation process, the power consumption P of the slope monitoring equipment is mainly considered. w, voltage U, acquisition frequency and other parameters. The power consumption P is generally given in the instruction manual of the slope monitoring equipment. w And the voltage U.

[0044] First, this embodiment takes into account the effective illumination time of the solar photovoltaic panel in practice and the actual working time of the battery on rainy days, and uses the power consumption and working time of the slope monitoring equipment as well as the utilization efficiency of the solar panel and the effective illumination time of the solar photovoltaic panel as calculation parameters to determine the power P required by the solar photovoltaic panel in real-time working conditions. s1 , calculated according to the following formula:

[0045]

[0046] Where A is the working time of the slope monitoring equipment, P w is the power consumption of the slope monitoring device, B is the utilization efficiency of the solar panel, and C is the effective illumination time of the solar photovoltaic panel. When the slope monitoring device works in real time, due to the difference between the working time of the device and the effective working time of the solar panel, this embodiment calculates the required parameters of the solar panel according to the cycle of each day, that is, A=24. The solar panel has a certain damage to the battery charging. The utilization efficiency B of the solar panel is calculated as 60%-80%. The effective illumination time C of the solar panel within the working time A of the slope monitoring device is calculated as 4-8 hours. Therefore, the above formula can be converted into:

[0047]

[0048]

[0049] Considering the actual situation in Guangdong and the remote location of the slope project, which makes operation and maintenance difficult, the maximum solar panel power P is used according to the minimum effective illumination time and utilization efficiency. s1 To ensure sufficient power conversion, according to the formula Calculate, P s1max =10P w .

[0050] In addition, the power consumption, working time, nominal voltage of the slope monitoring equipment, the energy storage efficiency of the battery and the working time of the battery in rainy weather are used as calculation parameters to determine the capacity S required by the battery in real-time working conditions. b1 , calculated according to the following formula:

[0051]

[0052] Where A is the working time of the slope monitoring equipment, P wis the power consumption of the slope monitoring equipment, E is the energy storage efficiency of the battery, U is the nominal voltage of the slope monitoring equipment, and D is the working time of the battery in rainy days. Similarly, the required parameters of the solar panel are calculated according to the cycle of each day, A=24. In addition, the energy storage efficiency of the battery is calculated according to 70%-80%. When the working time on rainy days is D, the maximum required capacity of the battery is used to ensure sufficient power. At this time, the required capacity of the battery is calculated as follows:

[0053]

[0054] Among them, E min is the minimum value in the battery energy storage efficiency range. Substituting the above parameters into the formula is converted to:

[0055]

[0056] Therefore, the above calculation method can more reasonably determine the selection parameters of solar panels and batteries under real-time working conditions.

[0057] In addition to the parameter calculation for the slope monitoring device in real-time operation, this embodiment also adds the influencing factor of the dormant working mode of the slope monitoring device, and determines the power P required by the solar photovoltaic panel in the dormant working state by taking the power consumption, working time, collection frequency, and collection time of the slope monitoring device as well as the utilization efficiency of the solar panel and the effective illumination time of the solar photovoltaic panel as calculation parameters. s2 Then, the power consumption, working time, nominal voltage, acquisition frequency, and acquisition time of the slope monitoring equipment are used as calculation parameters to determine the capacity S required for the battery in dormant working conditions. b2 Since the equipment on the slope usually works at a frequency of minutes or hours, when measuring once every H hours, each data collection takes N minutes, and the power consumption of each collection is Then the daily power consumption becomes The power required by the solar panel is:

[0058]

[0059] Where A is the working time of the slope monitoring equipment, P w is the power consumption of the slope monitoring equipment, N is the collection time of the slope monitoring equipment, B is the utilization efficiency of the solar panel, C is the effective illumination time of the solar photovoltaic panel, and H is the collection frequency of the slope monitoring equipment.

[0060] After substituting the corresponding parameters, the formula is transformed into:

[0061]

[0062] At this time the current is Then the required capacity per day becomes Therefore, the required capacity of the battery is S b2 It can be calculated as:

[0063]

[0064] Similarly, A is the working time of the slope monitoring equipment, P w is the power consumption of the slope monitoring equipment, N is the collection time of the slope monitoring equipment, H is the collection frequency of the slope monitoring equipment, E is the energy storage efficiency of the battery, U is the nominal voltage of the slope monitoring equipment, and D is the working time of the battery in a rainy day environment.

[0065] After substituting the corresponding parameters, the formula is transformed into:

[0066]

[0067] Therefore, the above calculation method can more reasonably determine the selection parameters of the solar panels and batteries in dormant working conditions.

[0068] In addition, the rated current selection of the solar controller required by the automated monitoring equipment in real-time operation and dormant operation is the same, that is, the controller only needs to meet the working current of the current equipment, and the working current mainly depends on the ratio of the power of the solar panel to the battery voltage U_ and the ratio of the load power to the battery voltage. The larger one is selected. Therefore, this embodiment uses the rated voltage of the battery and the power consumption of the slope monitoring equipment and the power required by the solar photovoltaic panel in real-time operation as calculation parameters to determine the rated current I of the solar system controller, and calculates according to the following formula:

[0069]

[0070] Where P s1 is the power required by the solar photovoltaic panel in real-time operation, P w is the power consumption of the slope monitoring equipment, U - is the rated voltage of the battery; by comparing the ratio of the power required by the solar photovoltaic panel in real-time working conditions to the rated voltage of the battery with the ratio of the power consumption of the slope monitoring equipment to the rated voltage of the battery, the coefficient 1.2 is considered to take current fluctuations into account, and the larger value is taken as the rated current I of the solar system controller.

[0071] It can be seen that the technical solution of the present invention takes into account the influencing factors such as the effective illumination duration that the solar photovoltaic panels are actually exposed to, the actual working time of the battery on rainy days, and the sleep working mode of the slope monitoring equipment, and optimizes the parameter calculation scheme for the solar power supply system of the highway slope monitoring equipment, so that designers can more reasonably select the solar panel power, battery capacity and controller parameters in the solar power supply system of the highway slope monitoring equipment.

[0072] Based on the above calculation method, this embodiment also provides a solar power supply system parameter calculator for slope monitoring equipment. The calculator uses the solar power supply system parameter design method for slope monitoring equipment of this embodiment to automatically calculate the power required by the solar photovoltaic panel in real-time operation, the capacity required by the battery in real-time operation, the power required by the solar photovoltaic panel in dormant operation, the capacity required by the battery in dormant operation, and the rated current of the solar system controller. Figure 3 As shown,

[0073] The program of this calculator is set up with two main functions, one for calculating the power consumption in real-time operation and the other for calculating in dormant operation. The input parameter in real-time operation is the energy consumption P of the device. w , equipment voltage U, equipment working hours A, rainy day working hours D, battery rated voltage U_, after inputting, click the real-time working button, then the required value for real-time working can be calculated. The parameters to be input for dormant working are collection frequency H, collection time N, after inputting, click the dormant working button, then the required value for dormant working can be calculated. The calculated values ​​in the first column are the actual required values, and the values ​​in the second column are the actual selected values. That is, when the solar panel calculates the power P s1 When the rated current I is 50W, the solar system controller with a rated current of 100W can be selected on the market. When the rated current I is 10A, the solar system controller with a rated current of 10A can be selected. The battery capacity parameters of the battery are generally different for each manufacturer, so the first line is designed as the capacity S required for one day. b1 The second line is the capacity S required for D days of work on rainy days b1max .

[0074] The calculator of this embodiment can take into account the influencing factors such as the effective illumination duration that the solar photovoltaic panels are actually exposed to, the actual working time of the battery on rainy days, and the sleep working mode of the slope monitoring equipment, and optimize the parameter calculation scheme for the solar power supply system of the highway slope monitoring equipment, so that designers can more reasonably select the solar panel power, battery capacity and controller parameters in the solar power supply system of the highway slope monitoring equipment.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
