Definitions

  • the innovation relates to a gate alarm device for monitoring the gate open time of a gate according to the preamble of claim 1.
  • Such security areas can, for example, be areas in companies where products requiring confidentiality are still being developed and tested, e.g. in the area of technical development or prototype construction.
  • a gate contact on the gate the switching state of which corresponds to a closed state or open state of the gate and which is actuated directly by the gate in accordance with its position.
  • Local gate alarm devices in the gate area are controlled via a gate alarm control unit to which the gate contact is connected.
  • an acoustic loudspeaker and / or an optical beacon are activated and actuated as a local gate alarm device when the gate is open.
  • the object of the innovation is to develop a generic gate alarm device in such a way that improved monitoring of the gate open time of a gate is possible.
  • the gate alarm control unit contains a gate status display unit which displays the switching status of the gate contact and thus the opening status of the gate via an optical gate status indicator.
  • This gate alarm control device is preferably located in a monitoring room, for example in a gate room or company safety room.
  • the gate status display unit corresponds to a remote display, by means of which the opening status of even a distant and invisible gate can be read at any time.
  • the gate alarm control unit also contains a pre-alarm unit with a pre-alarm timer which is activated when the gate contact is switched over according to the open state of the gate and which initiates the expiry of a predetermined pre-alarm time.
  • the gate may be open without any alarm triggering or warning from the local alarm transmitter, i.e. that when the gate contact is switched over according to the closed state of the gate during the pre-alarm time, the pre-alarm unit with the pre-alarm timer is reset.
  • the gate alarm control unit also contains a main alarm unit with a main alarm timer which is actuated by the pre-alarm unit after the pre-alarm time has elapsed and which initiates the expiry of a predetermined main alarm time if the door contact does not switch over during the pre-alarm time in accordance with the closed state of the gate. Simultaneously with this activation of the main alarm unit by the pre-alarm unit, the local gate alarm transmitter is activated.
  • the gate If the gate is still closed during this main alarm time or if the gate contact is switched according to the closed state of the gate, the main alarm unit and the pre-alarm unit are reset and the local gate alarm transmitter is switched off. Until the main alarm time has elapsed, the gate can thus be closed without any measures or signaling taking place beyond the local gate area.
  • the gate alarm control unit further comprises an alarm and acknowledgment unit which is controlled by the main alarm unit after the main alarm time has elapsed, if the gate is not closed during the main alarm time or the gate contact is not switched over according to the closed state of the gate.
  • This alarm and acknowledgment unit contains a plant protection alarm transmitter for alarming the company plant protection (or another monitoring institution).
  • a remote display on the gate alarm control unit is thus made available for a monitoring person, with which it can be seen that an irregularity occurs at the monitored gate by a predetermined, critical gate open time (pre-alarm time plus main alarm time) being exceeded.
  • the alarm and acknowledgment unit comprises a manually operable acknowledgment button, which is to be actuated when the gate is then properly closed again, ie when the gate contact is switched according to the closed state of the gate to switch off the local gate alarm transmitter and to reset the main alarm unit and pre-alarm unit.
  • the plant protection alarm can therefore only be acknowledged by the plant protection on the gate alarm control unit (and not only by closing the gate) when the gate is closed again. After pressing the acknowledge button, the gate alarm device is again reset and armed overall.
  • the gate alarm device thus responds in a graduated form to the open state of a door to a security area: in a first, predetermined period of time as a pre-alarm time, the door may be open without any alarm triggering. After this time in a second period as the main alarm time, a local reminder and warning assigned to the gate area is issued via acoustic and / or visual alarm devices for closing the gate. This is the last option to close the gate without any further consequences, since only by closing the gate within this time period the local alarm devices are switched off and reset.
  • This graded monitoring ensures, on the one hand, that the door runs smoothly when the door is operated correctly within the permitted, predetermined door open times, with no unwanted interference from local alarms being switched on, particularly during the pre-alarm time. These are only switched on when the pre-alarm time has actually been exceeded, for example due to carelessness. Only when it can be assumed that a serious irregularity or malfunction occurs at the monitored gate after the subsequent main alarm time has elapsed, will the plant security be called for a remote control. Monitoring of the expiry of a critical and impermissible gate open time is carried out automatically by the gate alarm control unit. The alarm for The plant protection remains in effect until a check is actually carried out and the gate is closed, after which an acknowledgment is only possible via an acknowledgment button on the control unit and the system can be armed again.
  • the gate status display preferably consists of two indicator lamps of different colors, a green indicator lamp for the closed state and a red indicator lamp for the (more critical) open state of the gate being provided based on conventional color codes.
  • the expiry time of the pre-alarm time and / or the main alarm time should be designed to be adjustable on the pre-alarm unit or main alarm unit. This ensures universal use and the ability to adapt to different monitoring conditions.
  • the local gate alarm should consist of both an optical alarm as a beacon and an acoustic alarm as a loudspeaker, both alarms should be controllable independently of each other. This enables effective local alarms that are adapted to different needs.
  • a permanent, acoustic alarm has a disruptive effect in the long run, especially if the fault was not caused by unauthorized persons but, for example, by a technical defect in the door operator and longer times are required before an error is shut down and the door is closed properly.
  • the local, visual alarm signal should be preserved so that a malfunction is also indicated in a long-term case.
  • outputs are created there on the alarm and acknowledgment unit, to which device-external work safety alarm devices can be connected as optical and / or acoustic alarm devices. This means that the plant security or other monitoring personnel can be alerted at other locations or additionally at other locations, such as where the gate alarm control unit is installed.
  • an acknowledgment button could also be attached to the device with a corresponding connection if required.
  • the gate alarm device or the gate alarm control device is designed for a special function.
  • the main alarm time can be set to zero. With this setting, the function of the pre-alarm unit is also switched off. If the monitored gate is now opened, the plant security is immediately alerted and a local gate alarm, in particular a rotating light, is activated.
  • the gate alarm device works as an alarm system that immediately alerts the plant security when a gate is opened. Such monitoring is useful for gates or doors that should not normally be opened, e.g. Emergency exits.
  • each gate alarm control unit of the above-described design for several gates and doors in one unit with a common supply unit.
  • the construction can take place in a common housing, and each alarm control device assigned to a gate can be designed as a plug-in circuit board with the necessary signal transmitters and actuating elements.
  • a gate alarm device 1 shows a block diagram for a gate alarm device 1, which comprises a gate alarm control device to which a gate contact 3, local tone alarm transmitter in the gate area as a local beacon 4 and local loudspeaker 5, and a device-external work safety alarm device as a device-external alarm lamp 6 and device-external alarm speaker 7 are connected are.
  • the gate alarm control unit contains a gate status display 8, a pre-alarm unit 9, a main alarm unit 10 and an alarm and acknowledgment unit 11.
  • the gate status display unit 8 contains a red and green lamp as a green light-emitting diode LED 12 for indicating the closed state of the gate and a red light-emitting diode LED 13 for displaying the open state of the gate in accordance with the switching state of the gate contact 3.
  • the gate contact 3 is further connected to the pre-alarm unit 9, whereby the sequence of a predetermined pre-alarm time VAt is started when the gate is opened. If the gate or gate contact 3 is closed within the pre-alarm time VAt, no alarm is given.
  • the beacon 4 and the loudspeaker 5 are activated via a control line 14, as is a yellow lamp as a yellow LED 15.
  • the sequence of the predetermined main alarm time HAt in the main alarm unit 10 is started . (For the functional sequence see also flow diagram according to Fig. 2.)
  • the beacon 4 and the loudspeaker 5 are switched off again via a control line 16 and the gate alarm control unit 2 is reset overall.
  • the loudspeaker 5 is switched off via the control line 16, while the rotating beacon 4 remains switched on.
  • the alarm and acknowledgment unit 11 is activated, a red alarm lamp flashing as a red alarm LED 17 and the device-external alarm lamp 6 and the alarm loudspeaker 7 being activated for alarming the works protection service WSD. Only when the information that the gate or gate contact switch is properly closed again is supplied via the connecting line 18 for the gate contact 3 of the alarm and acknowledgment unit 11 can the arrangement be reset and armed via an acknowledgment button 19 and a control line 20 .
