Abstract
A snow removal system wherein snow removers located in remote locations can be monitored and controlled at a computing device. Data collected by sensors on the snow removal unit or data collected from a secondary source can be used to control the operation of the snow removers. In one embodiment, data regarding whether it is snowing at a particular location can be collected by moister sensors on the snow removal device and verified by on-line contemporaneous weather reports corresponding to the same location.
Claims15
A method of monitoring a plurality of railroad switch snow removal devices, the method comprising:
- monitoring whether a snow removal device is on or off;
- querying data from a weather reporting source and determining whether the snow removal device should be on or off;
- determining if there is a discrepancy regarding whether the snow removal device is on or off;
- and
- automatically alerting an operator if a discrepancy is detected and continues to exist for a delay period.
A method of monitoring a plurality of railroad switch snow removal devices, the method comprising:
- measuring at least a temperature at a location of a snow removal device to determine if snow is falling at the location;
- querying data from a secondary source of weather information for information relating to whether snow is falling at the location;
- determining if there is a discrepancy regarding whether snow is falling at the location;
- and
- automatically alerting an operator after a discrepancy is detected and continues to exist for a delay period.
A railroad snow removal network comprising:
- a plurality of snow removal devices positioned at geographic locations, wherein each snow removal device is configured to automatically turn on when snowfall is detected;
- a computing device configured to acquire weather data from a weather reporting source wherein the data corresponds to the geographic locations of the snow removal devices,
- wherein the computing device is configured to send an alert when a snow removal device is turned off when the weather reporting source indicates that snow is falling at the corresponding location for a first delay period, and
- wherein the computing device is configured to send an alert when the snow removal device is turned on when the weather reporting source indicates that snow is not falling at the corresponding location for a second delay period.
