System and method for determining and controlling status and location of an object
Techniques are described with regard to determining and controlling a location and status of assets directly and/or indirectly. The techniques may be used to track and control the respective locations and status of any number of objects. Applications include but are not limited to tracking dry and refrigerated trailers and their status in a supply-chain yard; tracking pallets and boxes and their status in a warehouse; tracking items in a retail environment; tracking finished goods and work in progress in and around a manufacturing plant; tracking vehicles in a parking lot; tracking cargo and equipment at an airport; tracking equipment in a lay down yard; etc. In all cases the laborious and error prone data gathering is replaced with automated data collection methods reducing cost, increasing accuracy, and increasing efficiency.
1. A method for determining and controlling a status of an asset in a facility using a central control server, comprising:
receiving, at said central control server, communication from a plurality of mobile vehicles;
collating and aggregating, at said central control server, information from said received communication across a predetermined time interval and a predetermined geographical range of space;
based on said collated and aggregated information, determining by the central control server, the status of the asset and computing by an algorithm at said central control server used to locate positions of assets the location of the asset in the facility;
based on said collated and aggregated information, generating, at said central control server, at least one actuator action for said asset;
transmitting, by said central control server, said at least one actuator action intended for said asset; and
further comprising, by said central control server:
gathering and subsequently collating information gathered by additional stationary sensors;
collating and aggregating information about mobile vehicle location, speed, and heading of a particular mobile vehicle of said plurality of mobile vehicles and generating a list of assets that are in range at said location; reverse engineering said information to determine where in a 3D coordinate point in the facility and when an asset having equipment is in range; and based on said information computing a most likely location of said asset at a given time;
resolving inconsistent data in said collated information by identifying, weighing, and applying particular redundancies in the collated information to increase overall accuracy of said information;
comparing said collated information with data entered by human operators or predicted by system models, and determining a reliability of data from each data source;
comparing data between user generated asset movement information and said computed most likely asset location information and using similar data to increase location accuracy of said asset;
when particular data from said data from each data source is determined to be unreliable, replacing said unreliable data with said data determined reliable;
presenting current status information to human operators or other automated control modules;
receiving input from said other automated control models and said human operators; and
transmitting control instructions to said plurality of mobile vehicles, said instructions comprising:
actions on the asset actuators; and
actions on the mobile vehicle trajectory.
2. The method of claim 1 , wherein said at least one actuator action comprises any of:
turn on;
turn off;
adjust temperature setting;
adjust communication protocol;
adjust communication frequency; and
clear error codes.
3. The method of claim 1 , wherein said central control server communicates with said mobile vehicle over any of:
cellular infrastructure;
cellular infrastructure comprising any of: 3G, 4G, 5G, 1×RTT, GPS, GSM, or CDMA;
Y-max;
802.11x;
mesh networks;
Zigbee; and
any communication technology.
4. The method of claim 1 , wherein generating said at least one actuator action further comprises using data from any of or any combination of a human source, a third party control system, and a business rule.
