public class RoofInfo
extends Object

NEEDS UPDATE 16.10.02 A helper class collecting as much information about a roof as possible. The information gathered consists of 24 individual triggers. They can be represented in the STELLA-roof curcuit by checking the (potentialfree) bridges in the following relays (see also JRoofView):

• T1: K2 10-6^*
• T2: K12 10-6^*
• T3: K6 10-6^*
• T4: K16 10-6^*
• T5: K3 10-6
• T6: K4 10-6
• T7: K13 10-6
• T8: K14 10-6
• T9: K8 10-6
• T10: K10 10-6
• T11: K18 10-6
• T12: K20 10-6
• T13: K103 3-4
• T14: K113 3-4
• T15: K104 13-14
• T16: K114 13-14
• T17: K105 13-14
• T18: K115 13-14
• T19: K01 11-7
• T20: K03 11-7
• T21: K101, fully used. Use a combination of
  !S0 & !S1 & T10 & T12 & T19 & T1 & !T23
• T22: K111, fully used. Use a combination of
  !S0 & !S1 & T10 & T12 & T19 & T2 & !T24
• T23: K102, fully used. Use a combination of
  !S0 & !S1 & T10 & T12 & T20 & T3 & !T21
• T24: K112, fully used. Use a combination of
  !S0 & !S1 & T10 & T12 & T20 & T4 & !T22

^*: Not potential free, but on the same potential used for retrieving S0-S3 (limit switch failure, motor protection, roof open, roof shut).

The individual switches T1-T24 mean (normally in a N/S-pair):

• T1, T2: limit switch on open.
• T3, T4: limit switch on shut.
• T5, T7: X-switch on shut.
• T6, T8: X-switch on open.
• T9, T11: lock deployed.
• T10, T12: lock receded.
• T13, T14: command fast move.
• T15, T16: command deploy lock.
• T17, T18: command recede lock.
• T19: command open is set (no N-S pair).
• T20: command close is set (no N-S pair).
• T21, T22: command slide open.
• T23, T24: command slide shut.

Field Summary

private boolean	open If this is true, the roof is open and no problems have been seen.
private static String	OPEN The trigger state without the leading 0F of the roof for total open.
private boolean	shut If this is true, the roof is closed and no problems have been seen.
private static String	SHUT The trigger state without the leading 0F of the roof for total shut.
private Trigger[]	t24 The status of all triggers.

Constructor Summary

RoofInfo()
Constructs a new roof-info whithout any information in it.

Method Summary

Trigger[]	getTriggers() Returns all triggers.
boolean	isOpen() Returns true, if the roof is open and all switches have reported in the state necessary for a true, flawless open.
boolean	isShut() Returns true, if the roof is shut and all switches have reported in the state necessary for a true, flawless close.
static RoofInfo	parse(String raw) Returns a new roof info object, parsed from a hex-representation of the idividual bits T1-T24.
void	setTrigger(Trigger[] trigger) Sets all triggers.

Field Detail

OPEN

private static final String OPEN

The trigger state without the leading 0F of the roof for total open.

Constant Field Values

SHUT

private static final String SHUT

The trigger state without the leading 0F of the roof for total shut.

See Also:

Constant Field Values

t24

private Trigger[] t24

The status of all triggers.

open

private boolean open

If this is true, the roof is open and no problems have been seen.

shut

private boolean shut

If this is true, the roof is closed and no problems have been seen.

Constructor Detail

RoofInfo

public RoofInfo()

Constructs a new roof-info whithout any information in it. All trigger arrays are constructed, but not assigned with any triggers.

Method Detail

parse

public static RoofInfo parse(String raw)

Returns a new roof info object, parsed from a hex-representation of the idividual bits T1-T24. Input to this method is the direct reading of a roof switch, like !0F07A3FAFF. The first three characters are not used, thus the actual string parsed looks like:

              0SAABBCC
       

Herein, S is the 4-bit hex-representation of S0 to S3, AA to CC is a hex-representation of T1-T20, Meaning that the last four bits are not used, but reserved for direct assignment to T21-T24.

As T21-T24 cannot be deduced directly (relay fully wired), it is constructed from S's and T's in the following way:

       T21 = !S0 & !S1 & T10 & T12 & T19 & T1 & !T23
       T22 = !S0 & !S1 & T10 & T12 & T19 & T2 & !T24
       T23 = !S0 & !S1 & T10 & T12 & T20 & T3 & !T21
       T24 = !S0 & !S1 & T10 & T12 & T20 & T4 & !T22
       

isOpen

public boolean isOpen()

Returns true, if the roof is open and all switches have reported in the state necessary for a true, flawless open. This equals the triggers in OPEN.

isShut

public boolean isShut()

Returns true, if the roof is shut and all switches have reported in the state necessary for a true, flawless close. This equals the triggers in SHUT.

getTriggers

public Trigger[] getTriggers()

Returns all triggers.

setTrigger

public void setTrigger(Trigger[] trigger)

Sets all triggers.
