Definitions
- Electro-mechanical switchgear especially alarm system
- the invention relates to an electromechanical switchgear system with a signal-activating receiving part, which triggers a switching process in a microprocessor after checking the authorization of the received signal.
- the invention relates in particular to an alarm system consisting of an alarm center which can be activated by a signal, which is provided with sensors for monitoring one or more rooms against unauthorized entry, and at least one key lock system for arming and / or Disarm the alarm system.
- the object of the present invention is to develop a switchgear of this type which manages with a transmitter and receiver part without complicated wiring and can be integrated into existing systems.
- the system according to the invention essentially consists of a magnetic switching element which is attached to the entrance door and at least one transmitter which is firmly attached to the key.
- a receiver connected to the alarm center can be reached via this transmitter, which can arm or disarm the system.
- the locking functions can be expanded further in that when the key is turned to the left in the lock to be locked, the switch or switches arranged inside the key are switched in a contactless manner in a specific sequence. With each switching process, a pulse is sent to the processor in the key, which sends a coded signal to the receiving part of the alarm system.
- the signals arriving in the receiving part in a specific sequence are checked by a microprocessor. If the incoming code matches the authorization code, the microprocessor forwards a signal to activate the alarm system to the alarm center.
- the coded radio signal for deactivating the alarm system is sent, analogously to the previously described locking process. It is advantageous if the code of the radio signal is changed via a random generator each time the door is closed, so that knowing the radio code cannot be used for unauthorized entry.
- An emergency function in the key transmitter is ensured in that if the radio signal is absent, the alarm system is deactivated manually.
- the user of the alarm system experiences this in that an acoustic or optical signal is generated by the alarm center after the door is opened. Thereupon the user has the opportunity to manually disarm the alarm system within a certain time interval.
- he can have the code entered in a key transponder read in by the alarm center, this preferably being done via a magnetic coil which is connected to a microprocessor. It is possible to equip the transmitting and receiving system of the alarm system according to the invention in such a way that up to ten different key transmitters can be read in and checked.
- the respective key identifiers can be changed, which is preferably done via a master card by means of a magnetic coil and microprocessor of the receiver. It is advantageous if transponder-controlled, key authorizations are assigned or deleted using this master card alone.
- FIG. 1 basic structure of the alarm system according to the invention
- Fig. 2 block diagram of the alarm center
- FIG. 1 the lock 1 with key 2 and magnetic field generator 3 is shown.
- the magnetic field generator 3 is arranged between the lock 1 and the door handle 4 and, as can be seen from the section in FIG. 1 a, can also be positioned concealed in the door panel or support plate 5.
- the reed switch 6 As soon as the key 2 is turned in the lock 1, the reed switch 6 is exposed to a force due to the magnetic field effect, so that the reed contacts 6a, 6b are closed. Then a signal is emitted via the key transmitter 7 in the direction of the alarm center 8, which checks the signal and, if necessary, arming or disarming the system.
- Fig. 2 it is indicated how the signal processing process takes place in the receiving part of an alarm center.
- the signal processing process takes place in the receiver module.
- the coded signal 10 emitted by the transmitter 9 is received via the antenna module 11 and its switching authorization is checked in the processor 12. If the code is not recognized, no signal is forwarded. If the received code is If justified, an electrical pulse 13 goes to a transistor 14, which amplifies the pulse 15, so that a relay or transistor 16 can be controlled, which in turn arm or disarm 17.
- the switchgear according to the invention can be used for various switching operations, preferably those with an electromechanical drive, but also previously stationary power connections.
- the following areas of application can be mentioned as examples: the drive of blinds, roller shutters or water pumps in the household area and servo motor drives in the industrial and leisure area.
- stationary energy supply new solutions can be found for switching heating devices on and off, for stove-oven energy supply, for the stand-by operation of television sets, video recorders, etc., or for external sockets.
- two reed switches are combined in a key or switch system to form a multi-component switch. This results in an improvement in the ease of use and an increased security in the closed position.
- signal sequences can be triggered via the reed switches, e.g. 1-2 with a right turn or 2-1 with a left turn of the key or switch in the magnetic field.
- the switchgear could thus recognize based on simple logic whether the system should be activated or deactivated.
