- each means of connecting the unit 31 provides and / or receives specific signals, such as this is described in detail below.
- the first means of linking unit 31 provide signals designated UC1_OK, UC2_OK, ORDER1 and CRS_END, and receive the signals UC2_OK and CRS_END and a signal designated ORDER2.
- the control means 30 do take more account of the instructions provided by unit 31.
- the ORDER1 signal is supplied as a setpoint by unit 31, and allows unit 32 to control the validity of the instruction provided by unit 31.
- Unit 32 can determine if the ORDER1 signal is correct when the access door is locked, or when the lock works as a time lock.
- unit 31 sets the CRS_END signal to low, the motor likely to change the position of the bolt 22 can start in the direction defined by the control means 30.
- this cam maintains the CRS_END signal at low level, allowing this cam to continue its race.
- signal CRS_END is set high, and the motor is again blocked. So if unit 31 wants apply the ORDER1 and ORDER2 signals, it puts the CRS_END signal low for 100 ms.
- the signal CRS_END also allows unit 31 to detect if the came to realize its movement. Unit 31 can thus detect an engine problem, if the signal CRS_END initially at the high level is maintained at the low level for a predetermined period, typically less than 200 ms or more than 5 s.
- the UC2_OK signal is high, this signal indicates that unit 32 is operational. If unit 32 is reset, it puts the signal UC2_OK at the level low, then this signal goes high again when this reset procedure is complete. The unit 31 can impose a low level on the UC2_OK signal and, in this case, the control means 30 no longer take into account the ORDER2 signal.
- the ORDER2 signal is supplied as a setpoint by unit 32. This signal is redefined every half-second, and corresponds to an "unlock request” when this signal is high, and at a “request to lock "when this signal is low.
- the second means of connecting the unit 31 provide signals designated EEP1, MDE0, MDE1, MDE2 and RESET2, and receive signals designated EEP2 and RESET1.
- the EEP1 signal supplied by the unit 31 is used to indicate to unit 32 that unit 32 can access the EEPROM memory without risk of conflict with the unit 31.
- the signal EEP1 is used to indicate to unit 32 the period during which access to memory EEPROM is reserved for unit 31. Every second, the unit 31 sets the signal EEP1 to the high level or to the level low. Thus, the signal EEP1 at the high level indicates that access is reserved for unit 31, and therefore unit 32 cannot access EEPROM memory.
- the signal EEP2 supplied by the unit 32 is used to indicate to unit 31 that unit 31 can access EEPROM memory without risk of conflict with unit 32.
- the signals MDE0, MDE1 and MD2 supplied by the unit 31 to the unit 32 represent the current activity of the unit 31.
- Table 1 represents eight different activities of the unit 31, as well as the predetermined values of the signals MDE0, MDE1 and MD2, associated with these activities.
- Activity A corresponds to an ongoing failure of a component of the control device 20, for example an inconsistency in the content of the EEPROM memory.
- Activity B corresponds to the provision of a new event in EEPROM memory.
- Activity C corresponds to an occupation during access User.
- Activity D corresponds to a synchronization of unit 32 by unit 31.
- Activity E corresponds to a remote control locking of said access door.
- Activity F corresponds to an activation of the emergency system 25.
- Activity G corresponds to a reliability check performed on components of the lock.
- Activity H corresponds to an operation in normal situation of unit 31, and is supplied by default at unit 32, such an operation being defined later in detail. So the signals MDE0, MDE1 and MDE2 go through the state "111", when the unit 31 goes from one state to another. Such changes can happen when the next second passes.
- the RESET1 signal allows the unit 32 to reset unit 31, when unit 32 lowers this signal for at least 40 ⁇ s. This procedure occurs when unit 32 detects that unit 31 is not operating in normal situation. In the event of a prolonged malfunction, the unit 32 keeps the RESET1 signal low, and the unit 31 is then disconnected.
- RESET2 signal is used by the unit 31 to reset or disconnect the unit 32.
- control signals of the control device 20 are static, when operation of the control device 20. Otherwise says, the signals EEP1, EEP2, MDE0, MDE1, MDE2, RESET1 and RESET2 are equal to low and high levels. Such advantageously allows control with precision of the level of each signal, which allows precisely control the activity in progress. So, this operation provides the control device 20 with a high noise immunity, unlike a operation based on dynamic signals.
- the third means of linking unit 31 provide signals designated WP, SCL and SDA to the EEPROM memory, and receive SDA signal from memory EEPROM.
- the signal WP allows the unit 31 to have access in write to said reserved protected area of the memory EEPROM.
- the SCL signal is the clock signal which allows synchronize data transfers from and to the EEPROM memory.
- the SDA signal provides serial data between the EEPROM memory and the unit 31, 32.
- the fourth connecting means of unit 31 provide a signal designated RST_SOS1.
- the signal RST_SOS1 allows to reset the system watchdog 24.
- the unit 31 When unit 31 operates in normal situation, the unit 31 resets the system of watchdog 24, reversing every second the level of this signal.
- unit 31 When unit 31 is no longer in activity, or if it wants to activate the backup system 25, unit 31 no longer resets the dog system guard 24.
- the unit's fourth connecting means 32 provide a signal designated RST_SOS2 which allows unit 32 to reset the watchdog system 24, and activate the backup system 25.
- the fifth means of connection for unit 31 receive a signal designated BOLT_LCK.
- the seventh means of connection for unit 31 provide a signal designated TXD, and receive a signal designated RXD.
- the TXD signal provides asynchronously data from unit 31 to external indicator 28, such as this is known to those skilled in the art.
- the RXD signal provides asynchronously data from outdoor indicator 28 to unit 31, such as this is also known to those skilled in the art.
- the eighth connection means of unit 31 provide signals designated REL1_SET, REL2_SET and REL_RST, these signals being used as signals of alarm control.
- the REL1_SET signal activates the first bistable relay alarms 29.
- the REL2_SET signal activates the second bistable relay alarms 29.
- the REL_RST signal deactivates the first and second bistable alarm relays 29.
- control system 23 with redundancy of the control device 20 comprises two units 31 and 32 which perform common functions relating to the management of a change of state of the lock according to predetermined conditions, and at the guarantee of the maintenance of the current state until the next change of state. Therefore, only the operation of unit 31, this unit then being chosen arbitrarily.
- a normal situation as a situation during which the two units 31 and 32 provide the same instruction to the control means 30.
- an abnormal situation like a situation at during which an internal or external effect at control device 20 modifies the operation of this device in relation to its operation in situation normal.
- Such an effect is usually caused by a disturbance the nature of which may be voluntary, for example example a change of position of the bolt 22 or a lock picking, or involuntary, by example component failure, activity adjacent industrial, or atmospheric activity such as a solar explosion or discharge high intensity electromagnetic.
- an exceptional situation like a situation producing following the detection of a disturbance or an abnormal situation resulting in: the supply of two different setpoints by the two units 31 and 32, for example one asking mechanism 21 to unlocking the access door, and the other asking its locking; or the absence of presence of activity of minus one of units 31 and 32.
- the control device 20 then triggers a specific procedure to restore the operation corresponding to the operation in normal situation prior to said detection.
- control device 20 there are basically two modes of operation of the control device 20: a operation in normal situation, and operation in an exceptional situation.
- Figure 4 represents operating chronograms of the redundant control device 20 according to the present invention, in the case of a normal situation during which the control device 20 will unlock the access door, then lock it again.
- references 41 to 58 of Figure 4 designate the timing diagrams of the signals RESET1, RESET2, RST_SOS1, RST_SOS2, UC1_OK, UC2_OK, ORDER1, ORDER2, CRS_END BOLT_LCK.

- the two units 31 and 32 reset periodically the watchdog system 24, such so that the backup system 25 is not activated.
- the signal RST_SOS1 (curve 43) and the signal RST_SOS2 (curve 44) are inverted so that the signal RST_SOS1 (curve 43) is set high when the signal RST_SOS2 (curve 44) is set low, and vice versa.

- the signal EEP2 (curve 55) is inverted every second, so that the signal EEP1 (curve 54) is set high when the signal EEP2 (curve 55) is set low, and vice versa.
- the means control 30 receive these two instructions as input and, after validation by the signal CRS_END (curve 49), provide the mechanism 21 with an order to maintain the current state of the lock, i.e. the motor does not is not triggered, and that the bolt 22 has not changed position.
- the signal CRS_END (curve 49) and the signal BOLT_LCK (curve 50) are at the high level.
- the control means 30 receive as input this change of status of the instructions and, after validation by signal CRS_END (curve 49), provide output to mechanism 21 the order to change the current state of the lock, i.e. to trigger the engine to change the position of the bolt 22.
- the signal CRS_END (curve 49) is set low so that the cam of this motor leaves its end position. Then this cam keeps signal CRS_END (curve 49) low so that it continues its course.
- the cam is at the end of the race, it puts the signal CRS_END (curve 49) at the high level, which blocks the engine.
- the access door is then unlocked. Other says, the bolt 22 has changed position, which is detected by the position change detection system bolt 26.
- the signal BOLT_LCK (curve 50) is then set to low level.
- the signal EEP1 (curve 54) is at the high level.
- the unit 31 has access by write to EEPROM memory, and write a new event in the reserved shared area of this memory, by via the SDA signal (curve 57) and the SCL signal (curve 58). For example, this event is the locking the access door at a time t6.
- the unit 31 informs the unit 32 that a new event is available in EEPROM memory, this which corresponds to activity B described above in relation with table 1.
- the signal MDE0 curve 51
- the signal MDE1 curve 52
- the signal MDE2 curve 53
- the signal EEP2 (curve 55) being at high level, unit 32 has read access to the zone shared from EEPROM, and reads the new event available in this area, via signal SDA (curve 57) and the SCL signal (curve 58).
- the unit 31 informs the unit 32 that it works in normal situation, which corresponds to activity H described above in relation to the table 1.
- the signal MDE0 (curve 51) is maintained at high level
- the situation is therefore similar to the initial situation, and repeats, except for signal ORDER1 (curve 47) and signal ORDER2 (curve 48) which are at the high level so that maintain the current state of the lock, i.e. the locking the access door.
- Figure 5 represents operating chronograms of the control device according to the present invention, in the case of an exceptional situation linked, in this case, to no activity of unit 32.

- unit 31 decides to "disconnect" unit 32 maintaining the RESET2 signal (curve 60) at the low level. Thereafter, the control device 20 only works from unit 31.
- the access door is unlocked following the only supply of signal ORDER1 (curve 65) which is set at the high level, which realizes the change of state of the lock at the instant previously programmed.
- the control system 23 has implemented its function redundancy to manage a change of state of the lock according to predetermined conditions, and for guarantee the maintenance of the current state until the next change of state.
- the unit 31 does not no longer provides the instruction to lock the door again access, without outside technical intervention does not take place.
- the access door is then advantageously unlocked, which avoids to carry out a destructive intervention on this door or on his lock.
