[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 The embodiment of the present application discloses a generator level gauge measurement system for an intelligent controlled lighting tower, including a constant current source module 1, a conversion module 2, an acquisition module 3 and a control module 4.

[0032] The constant current source module 1 is used to output a supply current with a constant current value to the liquid level meter.

[0033] The conversion module 2 is used to detect the real-time voltage value of the liquid level meter and output the liquid level data based on the real-time voltage value.

[0034] The acquisition module 3 is used to acquire the resistance data of the liquid level meter and the detection data of the real-time voltage value.

[0035] The processing module is used to calculate the current value of the power supply current based on the resistance data and the detection data, and the processing module is used to send the calculation result to the constant current source module 1.

[0036] The implementation principle of the liquid level meter measurement system of the generator of the intelligent lighting tower in the embodiment of the present application is: it can realize accurate measurement of the liquid level. The constant current provided by the constant current source module 1 ensures that the power supply current is not affected by external factors, thereby improving the stability and reliability of the system. The conversion module 2 can accurately detect the real-time voltage value of the liquid level meter and output the liquid level data based on the voltage value, thereby realizing real-time monitoring and accurate measurement of the liquid level.

[0037] Reference Figure 2 The present application also discloses a method for measuring a liquid level meter of a generator of an intelligent lighting tower, including: Set the power supply current; the current value of the power supply current is constant, and the power supply current is used to provide electrical energy for the liquid level meter; Detect the real-time voltage value of the liquid level meter; Output liquid level data based on real-time voltage value.

[0038] Wherein: the constant current source module 1 is used to output a supply current with a constant current value to the liquid level meter.

[0039] Steps to set the supply current include: Get the resistance data of the liquid level meter; the resistance data includes the current resistance, maximum resistance and minimum resistance; Acquire detection data of the real-time voltage value; the detection data includes range information and resolution information, and the range information includes a range middle value, a range maximum value, and a range minimum value; Based on the resistance data and the detection data, the current value of the power supply current is calculated.

[0040] Among them: the resistance data is the current resistance, maximum resistance and minimum resistance of the liquid level meter. For example, the current resistance of a liquid level meter is 120Ω, the maximum resistance is 200Ω, and the minimum resistance is 10Ω; the detection data is the range information and resolution information of the conversion module 2. For example, the range information of a conversion module 2 is 0-10V (the middle value of the range is 5V, the maximum value of the range is 10V, and the minimum value of the range is 0V), and the resolution information is 1V.

[0041] The steps to calculate the current value of the supply current include: When the maximum value of the measuring range / maximum value of the resistance value is less than the resolution information / minimum value of the resistance value, the working condition data of the liquid level meter is obtained; the working condition data includes the liquid level decreasing, the liquid level increasing or the liquid level being uncertain; The operating data includes the case where the liquid level is reduced, and is calculated based on the maximum resistance value and the maximum value of the range; When the real-time voltage value∈preset range, the current value of the power supply current is updated based on the current resistance value and the maximum value of the range.

[0042] Specifically: When the maximum value of the range / maximum value of the resistance=10V / 200Ω<resolution information / minimum value of the resistance=1V / 10Ω, When the liquid in the container is continuously consumed (for example, the fuel in the tank is continuously consumed during the driving of the vehicle), the operating data includes a decrease in the liquid level, and the maximum value of the range / maximum resistance (10V / 200Ω) is calculated as the current value of the power supply current, and the current real-time voltage value is 6V.

[0043] At this time, if the liquid level drops to the minimum (i.e., the current resistance value of the liquid level meter = the minimum resistance value), the real-time voltage value is 0.5V < resolution information = 1V; therefore, the current value of the power supply current needs to be updated; The preset range is determined based on the range information; for example, the preset range is 0-20% and 80-200% of the maximum range. Substituting the above data, the preset range is 0-2, 8-20V, When the liquid is continuously consumed and the real-time voltage value drops to or below 2V, the maximum value of the range / current resistance value (10V / 40Ω) is calculated to update the current value of the power supply current.

[0044] The steps for calculating the current value of the supply current also include: The operating data includes calculations based on minimum resistance and resolution information when the liquid level rises; When the real-time voltage value∈preset range, the current value of the power supply current is updated based on the current resistance value and resolution information.

[0045] When the liquid in the container is increasing (for example, the container is used to collect the liquid), the operating data includes a liquid level increase, and the resolution information / minimum resistance value (1V / 10Ω) is calculated as the current value of the power supply current, and the current real-time voltage value is 12V.

[0046] 12V∈(8V,20V), then calculate (current voltage value - resolution information) / current resistance value to update the current value of the power supply current; after updating the power supply current, the real-time voltage value is updated to 10V, Continue to calculate (current voltage value - resolution information) / current resistance value to update the current value of the power supply current.

[0047] The steps for calculating the current value of the supply current also include: The working condition data includes the case where the liquid level is uncertain, and the calculation is based on the current resistance value and the mid-range value; When the real-time voltage value∈preset range, the current value of the power supply current is updated based on the current resistance value and the mid-range value.

[0048] Specifically: When the liquid level in the container needs to be maintained within the liquid level range (for example, the water in the pool is constantly circulating to keep it clean, and the water level in the pool needs to be maintained within a specific range), and the working condition data includes an uncertain liquid level, the mid-range value / current resistance value (5V / 120Ω) is calculated as the current value of the power supply current, and the current real-time voltage value is 5V. The liquid level may rise or fall, and the real-time voltage value will rise or fall accordingly. When the real-time voltage value∈(0,2V)∪(8V,20), the mid-range value / current resistance value is calculated to update the current value of the power supply current.

[0049] The steps for calculating the current value of the supply current also include: When the maximum range value / maximum resistance value ≥ resolution information / minimum resistance value, calculation is performed based on the resolution information and minimum resistance value.

[0050] For another example: when the maximum range of another conversion module 2 is 10V and the resolution information is 0.05V, and the maximum resistance of another liquid level meter is 100Ω and the minimum resistance is 1Ω, the maximum range / maximum resistance=10V / 100Ω>resolution information / minimum resistance=0.05V / 1Ω, then the resolution information / minimum resistance is calculated as the current value of the power supply current; at this time, if the liquid level drops to the lowest level, the real-time voltage value is 0.05V; if the liquid level rises to the highest level, the real-time voltage value is 5V.

[0051] It should be noted that the steps to output liquid level data based on the real-time voltage value include: Calculate the real-time voltage value / current value of the supply current, Compare the calculation result with the resistance data of the liquid level meter and output the liquid level data.

[0052] The implementation principle of the method for measuring the liquid level gauge of a generator of an intelligent lighting tower in the embodiment of the present application is as follows: by setting a constant power supply current, it is ensured that the voltage value change of the liquid level gauge at different liquid levels is only caused by the resistance change, thereby improving the measurement accuracy. At the same time, the voltage value of the liquid level gauge is detected in real time and the liquid level data is output based on the voltage value, making the entire measurement process more stable and reliable, and suitable for a variety of application scenarios.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
