[0043] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the system further includes a positioning accuracy evaluation module for regularly evaluating the accuracy of the positioning module to ensure the accuracy and reliability of the positioning information;

[0044] The positioning accuracy assessment module evaluates positioning accuracy using the following formula:

[0045]

[0046] Where: P acc (t) is the average positioning accuracy within time t; λ is the attenuation factor, which is used to consider the impact of historical positioning errors on the current evaluation; L true (τ) is the real geographical location of the forestry machinery at time τ; L est (τ) is the estimated geographical location of the forestry machine at time τ; e -λτ It is an exponential decay function, which is used to give more recent data a higher weight; range explanation: P acc The smaller the value of (t), the higher the positioning accuracy. acc When (t) approaches 0, it means that the positioning is very accurate;

[0047] The specific application process of the above formula is as follows:

[0048] 1. Data Preparation

[0049] Real geographic location data: The real geographic location data of forestry machinery in a specific time period is obtained through high-precision measurement equipment (such as GPS receivers, laser rangefinders, etc.), denoted as L true (τ). These data can be latitude and longitude coordinates, altitude, etc.

[0050] Estimated geographic location data: Obtain the estimated geographic location data of the forestry machinery in the same time period from the positioning module, denoted as Lest (τ). These data are calculated by the positioning module.

[0051] 2. Formula Application

[0052] Determine the attenuation factor λ: The attenuation factor λ is used to consider the impact of historical positioning errors on the current evaluation. In practical applications, the value of λ can be set according to specific circumstances and can be determined through experiments or experience.

[0053] Calculate the exponential decay function e -λτ :For each moment τ, calculate the exponential decay function e -λτ The purpose of this function is to give more recent data a higher weight, so that recent positioning errors have a greater impact on the evaluation results.

[0054] Calculate the positioning accuracy evaluation value P acc (t): According to the formula, two integrals are calculated: one is Another one is Then, substituting the values ​​of these two integrals into the formula, we can get the average positioning accuracy P within time t. acc (t).

[0055] 3. Results Analysis

[0056] Evaluate positioning accuracy: P obtained by calculation acc (t) value, the accuracy of the positioning module can be evaluated. acc The smaller the value of (t), the higher the positioning accuracy. acc A large value of (t) indicates that the positioning accuracy is low, and it may be necessary to further optimize the positioning module or adjust the value of the attenuation factor λ.

[0057] Optimize system performance: Based on the evaluation results, the system can be optimized. For example, if the positioning accuracy is low, you can consider upgrading the positioning module, improving the data transmission method, or optimizing the algorithm on the management platform.

[0058] As can be seen from the above, in this embodiment, the role of the positioning accuracy evaluation module is to regularly evaluate the accuracy of the positioning module to ensure that the provided positioning information is both accurate and reliable; in order to achieve this goal, the module adopts a specific formula for evaluation; this formula comprehensively considers the impact of historical positioning errors on the current evaluation and adjusts it by introducing an attenuation factor; at the same time, it also uses the difference between the actual geographical location and the estimated geographical location of the forestry machinery at a specific moment as the basis for evaluation; in addition, the formula also incorporates an exponential decay function, a design that gives recent data a higher weight in the evaluation, making it closer to the current actual situation; ultimately, the value obtained by calculation can intuitively reflect the level of positioning accuracy: the smaller the value, the more accurate the positioning; when the value approaches 0, it means that the positioning has achieved a very high accuracy.
