Embodiments of the present disclosure relate to vehicle signals communicated using POSIX-based directory interfaces. A method of obtaining vehicle signal data. The method includes reading, by a communication service layer application executing on a computer system, a vehicle signal directory, wherein the directory defines vehicle signals as full path file names; receiving, by the communication service layer application, a request from a second application for a value of a vehicle signal, wherein the request identifies the vehicle signal as a full path file name; obtaining, by the communication service layer application, the value of the vehicle signal; and returning the value of the vehicle signal to the second application.

This invention discloses an adaptive collaborative data acquisition system and method for power Internet of Things (IoT) terminals. It aims to solve problems related to limited terminal hardware resources, heterogeneous operating systems, and ensuring the real-time performance of core power services. The method establishes a three-in-one collaborative intelligent acquisition mechanism integrating "resources, links, and services," specifically including: a power service semantic perception module: identifying active core power service types in real time by reading process command lines and TCP ports; a nonlinear sampling frequency decision module: dynamically adjusting the sampling frequency based on service load and network link conditions using a piecewise nonlinear mapping function; a resource game Pareto optimization module: optimizing resource allocation by using an iterative algorithm to solve for the Nash equilibrium point between the probe and the service process online, with a hard constraint that the CPU utilization of the acquisition probe does not exceed 3%; and a lightweight data communication module: achieving efficient inter-process communication using a combination of POSIX shared memory, mmap zero-copy, and anonymous pipes.

A method of obtaining vehicle signal data. The method comprises reading a vehicle signals catalog by a communication service layer application that executes on a computer system, wherein the catalog defines vehicle signals as full path filenames; receiving a request for a value of a vehicle signal by the communication service layer application from a second application, wherein the request identifies the vehicle signal as a full path filename; obtaining the value of the vehicle signal by the communication service layer application; and returning the value of the vehicle signal the second application.

To provide vehicle signals communicated using a POSIX-based directory interface. [Solution] A method for acquiring vehicle signal data. The method includes: reading a vehicle signal catalog by a communication service layer application running on a computer system, wherein the catalog defines vehicle signals as full-path file names; receiving a request from a second application by the communication service layer application regarding the values ​​of vehicle signals, wherein the request identifies the vehicle signals as full-path file names; acquiring the values ​​of the vehicle signals by the communication service layer application; and returning the values ​​of the vehicle signals to the second application.
