Abstract

A system and method provides for the identification and monitoring of carriers within a pneumatic carrier system. Each carrier which is to be employed within the system includes an identification device such as a radio frequency identification (RFID) chip which has stored thereon identification information for the carrier. Positioned throughout the system are communications devices such as antennas and readers which are employed to read and/or write identification information on the chip. When a carrier is put in the system, a destination location can be associated with the particular carrier ID. This associated information is then employed to, among many things, monitor and confirm identity of the carrier as it moves to its destination.

Claims

1. A method for reinitiating operation of a pneumatic carrier system after shutdown of the carrier system where one or more pneumatic carriers are stranded within the system and where the carrier system comprises a plurality of user stations, pneumatic tubes and communication devices, comprising the steps of:

initiating power to the pneumatic carrier system;

identifying a stranded pneumatic carrier within the pneumatic carrier system;

using a communications device, reading identification information from the pneumatic carrier;

receiving the identification information from the communication device at a controller, wherein the controller is operative to;

obtain a carrier transaction record from a readable storage medium, wherein the transaction record includes destination information for the pneumatic carrier; and

route the pneumatic carrier to a location identified by the destination information.

2. The method of claim 1, wherein the step of reading comprises reading a radio frequency identification device (RFID) connected to the pneumatic carrier.

3. The method of claim 1, wherein components within the system are sequentially checked to identify the pneumatic carrier.

4. The method of claim 1, further comprising generating a first output at an origination user station of the pneumatic carrier.

5. The method of claim 1, wherein a second output is generated at a destination user station of the pneumatic carrier.

6. The method of claim 1, wherein said transaction record is generated at a time prior to initiating power to said system and generating said transaction record comprises:

obtaining identification information from an identification device connected to the pneumatic carrier at a carrier origination location in a pneumatic carrier system;

receiving destination information for the pneumatic carrier; and

storing the identification information and the destination information to the computer readable storage medium.
