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 storing a travel path of pneumatic carrier through a pneumatic carrier system where the pneumatic carrier system includes a plurality of user stations, pneumatic tubes and communication devices, comprising the steps of:

using a communication device, reading identification information from an identification device of a pneumatic carrier, wherein the pneumatic carrier is at an origination location within a pneumatic carrier system;

receiving a destination location for the pneumatic carrier via a user interface;

storing the identification information, the origination location and the destination location to a transaction record on a computer readable storage medium;

launching the pneumatic carrier through the pneumatic system to the destination location;

reading the identification device at a plurality of intermediate locations in the pneumatic carrier system using communications devices having known intermediate locations between the origination location and the destination location;

upon reading the identification device at an intermediate location, storing the known intermediate location of said communications device to the transaction record, wherein the transaction record records a travel path of the pneumatic carrier through the pneumatic carrier system; and

using the transaction record to identify a portion of the pneumatic system on which to perform maintenance.

2. The method of claim 1, wherein using the transaction record further comprising:

retrieving said transaction record from the computer readable storage medium at a time subsequent to storing information to the transaction record; and

identifying the travel path of the pneumatic carrier that generated the transaction record.

3. The method of claim 2, further comprising:

deactivating at least a portion of the travel path.

4. The method of claim 1, wherein the step of reading comprises reading a radio frequency identification device (RFID).

5. The method of claim 1, further comprising storing a time when the identification device was read at each intermediate location to the transaction record.

6. The method of claim 1, wherein the identification information includes at least one of:

a numerical identifier for the pneumatic carrier; and

a carrier type identifier.

7. The method of claim 2, further comprising:

cleaning at least a portion of the travel path.

8. The method of claim 2, further comprising:

identifying other carriers that passed through the travel path at a time subsequent to generating the transaction record.
