Abstract

Analysis that has been previously performed on digital sensor I/O features does not adequately test a set of sensor based features and system that will ultimately be installed in a customer's "nonideal" environment. Such parameters as electrical noise, cable types and lengths and typical customer sensor I/O attachments have not been adequately evaluated in the past.

Sensor Input/Output Subsystem Synthesizer

Analysis that has been previously performed on digital sensor I/O features does not adequately test a set of sensor based features and system that will ultimately be installed in a customer's "nonideal" environment. Such parameters as electrical noise, cable types and lengths and typical customer sensor I/O attachments have not been adequately evaluated in the past.

The interface between a digital sensor-based system and its application consists of several parameters: cable types, lengths, and routines used in the application; typical sensor I/O attachments such as relays, drivers, sensors and receivers; and electrical noise present in the customer's environment. The sensor I/O subsystem synthesizer ties up these parameters and presents them to a digital sensor-based system configuration during a systems assurance evaluation in a way that simulates typical customer's environment.

The synthesizer is composed of three individual units or areas: a customer sensor I/O interface box 1, an electrical noise generator 2 and customer-type cable busses 3. The diagram shows how the three areas and system being evaluated are related. The sensor I/O interface box presents typical customer- type transistor logic and contact sense inputs and outputs in various modes of operation to a digital sensor-based system. The cable busses are used to connect the digital sensor-based system to the sensor I/O interface box and to act as a medium fo...
