METHOD FOR REDUCING DETECTION DATA OF A MONITORING DEVICE IN A VEHICLE, AND METHOD FOR MONITORING A VEHICLE DEFECT IN NEAR REAL TIME USING SAME
First Claim
1. A method for reducing data of sensor devices, comprising:
- collecting detection data periodically detected from the sensor devices;
calculating an average value of the data collected during a cycle;
comparing each collected data with each calculated average value;
calculating, by an upper and lower value difference method, a deviation with previous data which is equal to or greater than an average value for a data in which a result of the comparing is equal to or greater than the average value, and a deviation with previous data which is less than the average value for a data which is less than the average value; and
storing the deviation value obtained by performing the calculating by the upper and lower value difference method.

Abstract
A method for reducing data of sensor devices in a vehicle includes collecting detection data periodically from the sensor devices and calculating an average value of the data collected during a cycle. The collected data may be compared with the calculated values and a deviation with previous data may be calculated by an upper and lower value difference method. A difference between the collected data and average values may also be calculated by a deviation method. The calculated value is stored. Data from a plurality of running vehicles may be periodically transmitted to a driving control center in order to monitor devices related to operations of all of the running vehicles in near real time.

3. A method for monitoring a vehicle defect in near real time, comprising:
-
collecting detection data periodically detected from a plurality of defect monitoring devices that are installed in a vehicle and monitor a defect associated with an operation of the vehicle; calculating a deviation from the collected detection data; generating a frame including the calculated deviation, a unique vehicle number set for each vehicle, a unique device number set in the corresponding vehicle, a final data which is equal to or greater than an average value during a previous cycle, a final data which is less than the average value during the previous cycle, and a bit size to express the deviation; transmitting the generated data frame to a driving control center; restoring the data to its original data by calculating each deviation of the previous data and of the bit size unit by distinguishing the transmitted vehicle number and device number in the driving control center; and detecting a defect in the corresponding device of the vehicle from the restored data. - View Dependent Claims (4, 5)
