Detailed Description

Cryo Compressor device class.

This class implements API No. 32 for the OVRO Cryo Compressor CAN module. Note that this class doesn't directly subclass IDL generated interfaces. I've decided instead to use delegation which should provide a small level of indirection if we ever decide to switch the underlying high level communication model.

Constructor & Destructor Documentation

carma::antenna::ovro::CryoCompressor::CryoCompressor	(	carma::canbus::nodeType	node,
		carma::canbus::CanOutput &	io,
		carma::monitor::OvroSubsystem &	ovroSubsys
	)

Constructor.

Parameters

node	Location id of this instance (node location id).
io	Reference to CanOutput class.

carma::antenna::ovro::CryoCompressor::~CryoCompressor ( )

Destructor.

Member Function Documentation

void carma::antenna::ovro::CryoCompressor::enableCompressor ( bool on )

Turn helium compressor on or off.

Parameters

on	flag indicating ON or OFF (on if true).

void carma::antenna::ovro::CryoCompressor::enableTemperatureServo ( bool on )

Turn temperature servo on or off.

This control command enables or disables the temperature servo loop.

Parameters

on	Enable temperature servo (true = enable, false = disable).

void carma::antenna::ovro::CryoCompressor::fillCompressor ( )

Fill the helium compressor.

This command will cause a one second mesasured charge of helium gas to be added to the helium compressor.

std::map<carma::canbus::msgType, std::string> carma::antenna::ovro::CryoCompressor::getControls ( ) const

virtual

Retrieve a map of this devices controls.

Returns: a map of control message string descriptions keyed by message id.

Reimplemented from carma::canbus::Device.

std::map<carma::canbus::msgType, std::string> carma::antenna::ovro::CryoCompressor::getHalfSecMonitors ( ) const

virtual

Retrieve a map of this devices half second monitor points.

The monitor points returned from this routine will be simulated if the device is in the OFFLINE state.

Returns: a map of the devices half second monitor points string descriptions keyed by message id.

Implements carma::canbus::Device.

std::map<carma::canbus::msgType, std::string> carma::antenna::ovro::CryoCompressor::getSlowMonitors ( ) const

virtual

Return a map of this devices slow monitor points.

These monitor points will be simulated every 5 seconds if the device is in the OFFLINE state.

Returns: a map of the devices slow (5 sec) monitor points string descriptions keyed by message id.

Reimplemented from carma::canbus::devices::XacDevice.

void carma::antenna::ovro::CryoCompressor::processMsg	(	carma::canbus::msgType	mid,
		std::vector< carma::canbus::byteType > &	data,
		bool	sim
	)

virtual

Process a CAN message addressed to the CryoCompressor module.

This routine is responsible for processing all CAN messages addressed to this device.

Parameters

mid	the 10bit message id (carma::canbus::msgType)
data	reference to the byte vector containing the raw data.
sim	Indicates if message is real or simulated.

See Also: carma::canbus::Device::processMsg

Implements carma::canbus::Device.

void carma::antenna::ovro::CryoCompressor::purgeCompressor ( )

Purge the helium compressor.

This command will cause a 0.5 second measured charge of helium gas to be purged from the helium compressor.

void carma::antenna::ovro::CryoCompressor::resetCompressor ( )

Reset the helium compressor.

void carma::antenna::ovro::CryoCompressor::setInletLouver ( float volts )

Set inlet louver position.

This control commands sets the position of the cabinet inlet louver. If the temperature servo is on, the temperature control loop will override this setting.

Parameters

volts Command voltage for louver (1.8-8.0 V).

void carma::antenna::ovro::CryoCompressor::setOutletLouver ( float volts )

Set outlet louver position.

This control command sets the position of the cabinet outlet louver. Again, if the temperature servo is on, the temperature control loop will override this setting.

Parameters

volts Command voltage for louver (1.8-8.0 V).

carma::canbus::Message carma::antenna::ovro::CryoCompressor::simulateMsg ( carma::canbus::msgType mid )

virtual

Produce a simulated CAN message for a given msgType.

This routine creates a Message with simulated data for an input message id. The returned message is automatically placed in the CAN message queue for retrieval and processing by the Master class. It thus can be used to test the processMsg method above.

Parameters

mid	the 10bit message id (carma::canbus::msgType)

Implements carma::canbus::Device.

void carma::antenna::ovro::CryoCompressor::updateFrameData ( )

virtual

Update Frame Data.

Reimplemented from carma::canbus::Device.
