Abstract
Description
Die Erfindung betrifft ein mechanisches codegeschütztes Schloß mit Alarmanlage.The invention relates to a mechanical code-protected lock with alarm system.
Das Schloß besteht aus beliebigen zylinderförmigen Schaltern als Öffner (Fig. 1a) und Schließer (Fig. 1b), die in Reihe (Fig. 2 T-A) und Parallel (Fig. 2 T-B) geschaltet sind, und einem Kreuzschalter (Fig. 2 T-C), der veranlaßt, daß der Motor links oder rechts drehen soll und dadurch die Verriegelung oder Entriegelung der Türe verursacht.The lock consists of any cylindrical switches as NC contacts ( Fig. 1a) and NO contacts ( Fig. 1b), which are connected in series ( Fig. 2 TA) and parallel ( Fig. 2 TB), and a cross switch ( Fig. 2 TC ), which causes the motor to turn left or right, causing the door to lock or unlock.
Die Funktion der zylinderförmigen Schalter:
durch Druck am Kopf von Teil 1 (Fig. 1a und 1b) wird Teil 1 und 2 untergeschoben.
Dadurch wird entweder Teil 4 zwischen Teil 5 und 6 geschoben und Verbindung
hergestellt oder Verbindung aufgelöst und entsprechend wird die Feder (Teil 3 Fig.
1) gespannt. Die gespannte Feder sorgt dafür, daß nach Aufhebung des Drucks alle
Teile in den ursprünglichen Zustand zurückkehren.
Das Einordnen der zylinderförmigen Schalter in Reihe und Parallel (T-A und T-B
Fig. 2) verursacht eine bestimmte Codierung. Wenn die Schalter in offener Position
0 und in geschlossener Position 1 bezeichnet werden, muß die Codierung des Schlosses
wie Tabelle in Fig. 2a aussehen.
Nach Einstecken des richtigen Schlüssels sollen alle in Reihe geschalteten Schalter
(S1, . . . . . S4) in geschlossener Position und in Parallel geschalteten Schaltern
(S5, . . . . . S13) in offene Position gebracht werden. Die Tabelle in Fig. 2a zeigt die
richtige Decodierung des Schlosses, d. h. die Position der Schalter S1, S3, S6, S8, S9,
S10, S13 muß durch Druck geändert werden. Dieser Vorgang sorgt dafür, daß die
Transistor-Basis T1 (Fig. 2) Masseanschluß bekommt und umgekehrt die
Transistor-Basis T2 (Fig. 2) von der Masse getrennt wird, dadurch sperrt T1 (Fig. 2)
und macht T2 (Fig. 2) leitend. Aufgrund dieses Vorgangs werden die Transistoren T3
und T4 (Fig. 2) leitend und Relais 1 (Fig. 2) wird angezogen. Dann hat Kreuzschalter
T-C (Fig. 2) Power und kann durch Schalten in Position 1 oder 2 den
Verriegelungsmotor in die eine oder andere Richtung bewegen, dadurch wird die
Tür verriegelt oder entriegelt. Solange der richtige Code durch den Schlüssel nicht
erreicht ist, gibt es in Punkt C (Fig. 2) keine Spannung und beim Umschalten des
Kreuzschalters (T-C Fig. 2) passiert gar nichts.The function of the cylindrical switch:
by pressing on the head of part 1 ( Fig. 1a and 1b) parts 1 and 2 are pushed under. As a result, either part 4 is pushed between parts 5 and 6 and connection is established or connection is broken and the spring (part 3, FIG. 1) is tensioned accordingly. The tensioned spring ensures that all parts return to their original state after the pressure has been released. Placing the cylindrical switches in series and in parallel (TA and TB Fig. 2) causes a certain coding. If the switches are designated in the open position 0 and in the closed position 1, the coding of the lock must look like the table in FIG. 2a. After inserting the correct key, all switches connected in series (S1,.... S4) should be moved to the closed position and switches connected in parallel (S5,..... S13) to the open position. The table in Fig. 2a shows the correct decoding of the lock, ie the position of the switches S1, S3, S6, S8, S9, S10, S13 must be changed by pressing. This process ensures that the transistor base T1 ( FIG. 2) is grounded and conversely the transistor base T2 ( FIG. 2) is separated from the ground, thereby blocking T1 ( FIG. 2) and making T2 ( FIG. 2) conductive. As a result of this process, the transistors T3 and T4 ( FIG. 2) become conductive and relay 1 ( FIG. 2) is attracted. Then cross switch TC ( Fig. 2) has power and can move the locking motor in one or the other direction by switching to position 1 or 2, this locks or unlocks the door. As long as the correct code is not reached by the key, there is no voltage in point C ( Fig. 2) and nothing happens when the cross switch (TC Fig. 2) is switched.
Um diesen Code zu entschlüsseln, muß man 7 aus 13 Schaltern drücken. Hier gibt es 213 = 8192 mögliche Kombinationen und Wahrscheinlichkeit liegt bei 1 zu 8192. Durch Erhöhen der Schalteranzahl kann man die Wahrscheinlichkeit bedeutend heben. To decode this code, you have to press 7 out of 13 switches. There are 2 13 = 8192 possible combinations and the probability is 1 in 8192. By increasing the number of switches you can increase the probability significantly.
Diese Art Verriegelung ist gut geeignet für eine Centralverriegelung im Auto zusammen mit dem Zündschloß.This type of locking is well suited for central locking in the car together with the ignition lock.
Das kann man erzielen, wenn man mehrere Schloßeinrichtungen parallel an das elektronische Teil anschließt (Fig. 4). Dadurch kann man mehrere Motoren zur Verriegelung oder Entriegelung der Türen in Betrieb nehmen.This can be achieved if several lock devices are connected in parallel to the electronic part ( Fig. 4). This means that several motors can be put into operation to lock or unlock the doors.
Dieses System läßt sich einfach mit der Alarmanlage nachrüsten. Beim Verriegeln der Türen bekommt der Set-Eingang der IC2a eine positive Spannung und bringt Q- Ausgang auf High und Q-Ausgang auf Low und entsprechend werden der Eingänge von IC2b K-Eingang auf High und J-Eingang auf Low gebracht Jetzt ist die Alarm anlage in Bereitschaft. Sobald die Tür geöffnet wird, wird der Türschalter S18 geschlossen. Das hat die Folge, daß der Transistor T6 sperrt und positive Flanke am Clock-Eingang von IC2b setzt Q-Ausgang auf High und macht Transistor T7 leitend und Relais 2 zieht an und dadurch wird Alarm ausgelöst. Durch das Entriegeln der Türe wird die Alarmanlage ausgeschaltet. Mit dem gleichen Prinzip kann man das Radio an die Alarmanlage anschließen, d. h. durch das Herausziehen des Schlüssels wird Alarmbereitschaft beim Radio ausgelöst.This system can be easily retrofitted with the alarm system. When the doors are locked, the set input of the IC2a gets a positive voltage and brings Q output to high and Q output to low and accordingly the inputs from IC2b are brought K input to high and J input to low. Now the alarm is plant on standby. As soon as the door is opened, the door switch S18 is closed. This has the consequence that transistor T6 blocks and positive edge at the clock input of IC2b sets Q output to high and makes transistor T7 conductive and relay 2 picks up and this triggers an alarm. The alarm system is switched off by unlocking the door. The same principle can be used to connect the radio to the alarm system, ie when the key is removed, the radio is ready for alarm.
