Abstract
An emergency shutdown test system, wherein the emergency shutdown test system includes an emergency shutdown device controller and sensors to provide data to the controller, the controller having a processor, a memory coupled to the processor and an auxiliary input, wherein an emergency shutdown test is stored in the memory, and the auxiliary input is adapted to receive a binary signal and sensor data. Routines are stored in the memory and are adapted to be executed on the processor to cause the emergency shutdown test to be performed in response to the receipt of the binary signal at the auxiliary input and to cause sensor data to be recorded in the memory during the emergency shutdown test.
Claims28
An emergency shutdown test system adapted to communicate with a portable handheld computing device, the test system comprising:
- an emergency shutdown device controller having:
- a processor;
- a memory coupled to the processor, wherein an emergency shutdown test procedure is stored in the memory;
- an auxiliary input coupled to the processor and adapted to receive a binary signal from a switch, wherein the switch is accessible to a user and coupled directly to the auxiliary input;
- a first routine stored in the memory and adapted to be executed on the processor to cause the emergency shutdown test procedure to be performed in response to the receipt of the binary signal at the auxiliary input;
- and
- a second routine stored in the memory and adapted to be executed on the processor to acquire data from a sensor and to cause the data to be stored in the memory, during the emergency shutdown test.
A control device test system adapted to communicate with a portable handheld computing device, the test system comprising:
- a device controller having:
- a processor;
- a memory coupled to the processor, wherein a control device test is stored in the memory;
- an auxiliary input coupled to the processor and adapted to receive a binary signal from a switch;
- a first routine stored in the memory and adapted to be executed on the processor to cause the control device test to be performed in response to the receipt of the binary signal from the switch at the auxiliary input;
- and
- a second routine stored in the memory and adapted to be executed on the processor to cause data to be acquired from a sensor and recorded in the memory during the control device test;
- a communication unit, coupled to the processor, to transfer the data to a user;
- and
- a third routine stored in the memory and adapted to be executed on the processor to cause the control device test to be performed in response to the receipt of a digital signal from the portable handheld computing device at the communication unit.
A method of conducting an emergency shutdown test on an emergency shutdown valve, comprising:
- storing an emergency shutdown test script in a memory of a controller,
- monitoring an input coupled to the controller for the receipt of a binary signal received from a test initiation switch that is accessible to a user;
- monitoring the input for the receipt of a digital signal received from the portable handheld computing device;
- activating the test script in response to at least one of the binary signal received from the test initiation switch, or the digital signal that is received from the portable handheld computing device;
- storing at least one predetermined limit in the memory of the controller;
- activating the test initiation switch to perform the emergency shutdown test, wherein a processor is responsive to the switch activation;
- acquiring sensor data from a sensor and storing the sensor data in the memory;
- and
- comparing the sensor data to the at least one predetermined limit and creating alarms if the difference between the sensor data and the at least one predetermined limit is greater than a predetermined threshold.
