Appendable system and devices for data acquisition, analysis and control
An appendable system includes a plurality of appendable devices that are adapted to interoperate with each other and/or a workstation via a communication network to monitor and/or control a process. Each of the appendable devices can communicate with one or more sensors and/or control outputs and includes a housing that facilitates mounting of the appendable device to a surface.
1. An appendable system for controlling a closed loop process, comprising:
a plurality of appendable devices, each of which includes an antenna, a transceiver, a processor, a memory, an input/output interface adapted to enable the processor to communicate with one of a sensor and a control output, and a housing adapted to facilitate surface mounting of the appendable device to an entity in a process control system; and
a computer system adapted to communicate with one or more of the plurality of appendable devices so that a first one of the plurality of appendable devices senses a first parameter of the process and a second one of the plurality of appendable devices controls a second parameter of the process based on the first sensed parameter as a result of the first parameter used in the closed loop process.
2. The appendable system of claim 1 , wherein each of the plurality of appendable devices is adapted to generate information associated with one of an alarm condition of the process and a condition of the appendable device.
3. The appendable system of claim 1 , wherein the computer system is further adapted to configure the plurality of appendable devices based on configuration information stored in one of a central database and the plurality of appendable devices.
4. The appendable system of claim 1 , wherein the computer system is further adapted to perform a security function that prevents unauthorized access to the appendable system.
5. The appendable system of claim 1 , wherein the computer system is further adapted to interface with a wireless handheld device.
6. The appendable system of claim 1 , wherein each of the plurality of appendable devices includes an internal power source that provides power using one of a capacitor, a battery, vibrations, light and a magnetic field.
7. The appendable system of claim 1 , wherein the housing is adapted to be mounted to a surface using one of an adhesive, a screw, a clamp, a magnet and a tie-wrap.
8. The appendable system of claim 1 , wherein the antenna is one of a wire whip, a coil integrally attached to the housing, conductive traces on a printed circuit assembly and a discrete wire coil.
9. The appendable system of claim 1 , wherein the computer system is one of a controller and a workstation.
