Definitions

  • the invention relates to a method according to the preamble of claim 1 for providing control of the component devices of an electromechanical locking system including at least a plurality of electromechanically controlled locking units.
  • Electromechanical locking and monitoring systems for a plurality of doors or other objects requiring to be locked are known in which each locking unit is separately connected via a cable to a central control unit, from which the basic programming of the system, as well as the subsequent continuous control of the locking units, is effected. Installation of a system of this kind is laborious and costly due to the considerable cable installing work and switching work required. Initial programming of the individual devices in the system and reprogramming when subsequent changes thereto are required is accomplished one by one from the central control unit, which is time consuming and increases the degree of communications needed.
  • One aim of the present invention is to provide a novel way of providing control for electromechanical locking systems, from which the drawbacks mentioned above have at least been reduced and preferably have essentially been eliminated.
  • a further aim is to develop the control system so that it becomes possible to provide a system which is constructionally uncomplicated and cost effective as to its installation and maintenance.
  • a still further aim is to improve the security of the electric control of the locking system and the possibility of flexibly modifying the operation of the component devices in the system to correspond to the circumstances applicable in each case.
  • a message is transmitted through the data transmission bus to all the component devices in the system and is provided with an identifier for the transmitting locking unit or device in question.
  • At least one (and preferably all) of the attachment units is provided with a control data register, into which identification data is fed relating to those devices, which are authorised to control the locking unit or device attached to the attachment unit in each case.
  • identification of the message and execution of the operations implied by the message is determined in each attachment unit on the basis of the identifier of said transmitting device and control data preprogrammed in the control data register.
  • Security for its part is improved by the fact that as an identifying address in the control messages to be transmitted through the data transmission bus is the identifier or identification data of the device sending the message, whereby those component devices for which the message is directed need not be named separately.
  • the execution of the operations implied by the message is determined on the basis of control data to be preprogrammed in each attachment unit, the operations to be accomplished can be encrypted in a code form in the messages passed through the data transmission bus.
  • each attachment unit is also provided with an operating data register, into which different operating data for the locking unit or device attached to that attachment unit are supplied. Then a control command for accomplishing the operation of a component device in the locking system can be formed in the attachment unit so that on the basis of the received message and the data in the control data register it is first determined, which part of the operating data register is to be utilised. Thereafter the control is provided on the basis of both the data in the operating data register and the data to be provided by indicator means, e.g. limit switches, in the locking unit or device and indicating the state of the device in each case.
  • indicator means e.g. limit switches
  • the method of the invention includes the use of a known form of programming device, for instance a portable micro computer, which is connected to said transmission bus for accomplishing programming of said registers.
  • a known form of programming device for instance a portable micro computer, which is connected to said transmission bus for accomplishing programming of said registers.
  • Each attachment unit can be separately programmed, but by arranging the programming device to operate through the data transmission bus parameters of the entire locking system can be put into a special programming state, under which the locking units or other component devices are allowed to utilise the data transmission bus only under the control of the programming device, the programming needed by the separate devices can be accomplished through any of the attachment units connected in the system.
  • Connection to the data transmission bus 8 takes place by means of a transmitter/receiver circuit 1, which is of a kind in which a received signal shows the state of the bus even when the device itself is transmitting, in other words the receiving mode is continuously on.
  • a timer/counter circuit 2 is used for timing reception and transmission operations and for computing values for desired delays.
  • a RAM memory circuit 3 is used as a data buffer, into which the actual operational data part in a received message is supplied.
  • An EEPROM memory circuit 4 is provided with a control data register, into which data is fed about those devices which are authorised to exert control over the operating device 6 attached to the attachment unit in question.
  • the memory circuit 4 also includes an operating data register, into which is fed different operating data for the locking unit or other operating device 6 attached to the attachment unit in question.
  • identification data for example, a password or encryption data for the operating device 6 is stored in the memory circuit 4.
  • a processing unit 5 controls the data transmission bus operations and the operations of the associated operating device 6.
  • "INPUT” in Figure 1 refers to the operational limits for the operating device 6 itself or the signals from limit switches connected to the device and indicating its state and operation in each case. When the device 6 is a locking device the limit switches indicate for instance different positions and states of operation for a lock bolt.
  • "OUTPUT” in Figure 1 indicates the role of the unit 5 in controlling the operation of the operating device 6, for instance its relays or an electric motor operating the lock bolt.
  • Figure 2 shows in principle how the transmission, reception and processing of a message 7 occurs. As will be clear from the foregoing, all these operations take place through the attachment unit in each device.
  • a message 7 can be associated with control, supervision or registration of data of the component devices depending on the application and the device.
  • a first operating device 6a (Device 1) transmits a message 7 into a data transmission bus 8.
  • the message 7 includes a data checking part 7a, an operating data part or data part 7b, an identifier part 7c for the sending device itself and a part 7d indicating the type of the message.
  • the device 6a transmits its message 7 when there is a change in its input or after a certain time has elapsed from a previous transmission.
  • the message 7 is sent via the data transmission bus 8 to all the other devices 6b, 6c ... etc. attached to the data transmission bus 8. Those of the devices 6b (Device 2), 6c (Device 3) ... etc., which need the message 7, start processing it further in phase 1.
  • the message 7 and the identification data of the various devices 6 that are authorised to the act on the message in question have been stored in the control data register in the EEPROM memory circuit 4 of the attachment unit for the device in question.
  • the identification data can be arranged as a special address list 9 in the EEPROM circuit 4 for speeding up and simplifying the operation.
  • the data checking part 7a of the message 7 is first checked against the identification data of the device 6 and in case of a correct match, the data part 7b of the message 7 is fed into a STATES buffer in the RAM memory circuit 3.
  • This buffer includes the data parts 7b of the messages from all the other devices in the system needed by the receiving device 6 in question.
  • phase 2 of device 6b a control command is formed in accordance with the control data register in the EEPROM memory circuit 4 and the data part 7b of the message stored in the RAM memory circuit 3.
  • the control command determines which part of the operation data register in the EEPROM memory circuit 4 is to be utilised.
  • phase 3 an OUTPUT control command is formed for the device 6 on the basis of its own INPUT state and the operation data register in the EEPROM memory circuit 4. Forming of the commands on the level of bits can be accomplished in a way known as such and will not be described more fully here.
  • Figure 3 shows the attachment of a programming device 10 to a data transmission bus 8 for programming one or more devices 6 in the system.
  • the means needed for this purpose are generally known and are indicated by the reference number 11.
  • the programming device 10 can be a fixed part of the system but it can, as well, be attached to an established system only when needed.
  • the various devices 6 in the locking system can be programmed either one by one or several at a time, for instance according to the type of the devices used.
  • the programming device 10 changes all the devices 6 in the system so that they are all in a programming state, whereby each is allowed to use the data transmission bus 8 only when the programming device 10 allows it.
  • the device 6 to be programmed is determined by a message, which includes the identification data for the device in question and its password , possibly in encrypted form (phase 1).
  • the programming can relate to the EEPROM memory circuit 4 of the device or the device can be, for instance, commanded to transmit the data in its EEPROM memory circuit into the programming device (phases 2 and 3).
  • This kind of system is advantageous and flexible i.a. due to the fact that its basic elements, the different locking units and the possible control or supervising devices therefor, as well as the principles for forming the system can remain the same, whereby the need for modification and changes for different applications can be taken account of simply through programming. Flexibility is increased by the fact that programming of the different devices can be accomplished through the respective attachment unit, and a separate portable programming device like a micro computer can be used for the purpose.
