Indoor Positioning System

In recent years, indoor positioning systems (IPS) are increasingly very important for a smart factory, and the Lora positioning system based on round-trip time (RTT) has been developed. This paper introduces the ranging characterization, RTT measurement, and position estimation method. In particular, a particle filter localization method-aided Lora pseudorange fitting correction is designed to solve the problem of indoor positioning; the cumulative distribution function (CDF) criteria are used to measure the quality of the estimated location in comparison to the ground truth location; when the positioning error on the x -axis threshold is 0.2 m and 0.6 m, the CDF with pseudorange correction is 61% and 99%, which are higher than the 32% and 85% without pseudorange correction. When the positioning error on the y -axis threshold is 0.2 m and 0.6 m, the CDF with pseudorange correction is 71% and 99.9%, which are higher than the 52% and 94.8% without pseudorange correction.

Regenerative Energy

The conventional distance estimation system only uses a constant speed and a constant level of road elevation to estimate the driving mileage for a vehicle. This technique leads to a low accuracy. In the current project, a new estimation technique namely; the Contour Positioning System (CPS) for an electric vehicle has been proposed. The CPS has a better estimation on the electric vehicle battery usage because of the consideration of road elevation, regenerative energy etc. In order to perform the CPS calculation, the elevation profile of the selected destination must be known. In this paper, the technique to extract the elevation profile i.e. latitude, longitude and altitude has been performed and evaluated using Google Maps or Google EarthÒ. This method enables the user to obtain the road information and compute the amount of energy needed to reach the said destination.

In order to improve the collision problem of getting information of RFID-assisted positioning system in the robot. This paper will build a mathematic model for the time slot method by quoting Markov chain, that use it as the basis analyze the time slot method performance and get the relationship between the number of the time slot and the electronic tag identification, so we can reasonable plan the positioning tag number. This technique is applied to the robotics positioning recognition system.

Contour Positioning System (CPS) is a new system invented for electric vehicles to calculate the remaining battery capacity for reaching a desired destination. Instead of using conventional electric car estimation in terms of distance, a CPS system can figure out extra energy needed when an electric car is traveling on different contour lines. Extra current will be drawn for generating torque required by the electric car on an inclined plane, for instance traveling uphill. By using coordinate conversion, sets of longitude and latitude readings can be converted into distance difference along the pathway and the elevation levels difference are calculated; the extra force and torque needed along an inclined plane can be further counted which will then lead to the extra current drawn from the electric car's battery pack. Data collections and real-time validations have been done to clarify the calculation results. By performing a series of battery capacity calculation, CPS can give a higher precision and accuracy of remaining battery life to reach the desired location
