Definitions

  • the invention relates to an information emergency call system with a central interrogation point, to which one or more information emergency call pillars are connected via cable connections for the transmission of supply voltages, voice signals and control signals.
  • the invention has for its object to provide an information emergency call system that is designed to be particularly user-friendly, can be used very flexibly and offers maximum security in the transmission of emergency calls and information.
  • a basic idea of the invention is to design the information emergency call pillars connected to the central query point in their control panel in such a way that the user can clearly decide whether he wants to make an emergency call or request information.
  • two separate actuation elements are provided, which can also be characterized in a special way for the intended purpose and the functions triggered by these separate actuation elements within the information emergency call system are such that a distinction can also be made in the central interrogation point as to whether it is the making of an emergency call or the making of an information request call, so that different reactions can also be triggered in the central call station, depending on what kind of call it is.
  • a third actuating element can be placed on the information emergency call pillar be provided, which is arranged at such a height above the ground on the control panel that it can also be easily reached by a wheelchair user or by a child, so that this group of people the possibility to make an emergency call is facilitated.
  • an additional microphone can be arranged in the immediate area of the third actuating element, into which the wheelchair user or the child can speak directly.
  • the information emergency call system can be designed such that each information emergency call column is connected to the central interrogation point via three line pairs.
  • a first pair of lines is used to transmit the voice signals that run from the central query station to the information emergency column
  • a second pair of lines is used to transmit the voice signals that run from the information emergency column to the central query station
  • a third line pair is used to transmit control signals between the information Emergency call station and the central call point.
  • the transmission of the control signals, which can take the form of data signals, over a separate line has the additional advantage that the typical difficulties Avoid that occur when voice signals and data signals are to be transmitted over a common line, since in this case one must either transmit the data in the range of very low frequencies, which reduces the transmission speed, or in the range of very high frequencies, in which the damping properties of the lines cause additional difficulties.
  • the first and second pair of lines can simultaneously serve to supply one polarity of a DC supply voltage. This DC voltage supply can be monitored in each information emergency column by its own monitoring device, so that if the supply voltage fails, a corresponding alarm signal is given to the central interrogation point via the third pair of lines.
  • Another basic idea of the invention is to increase the user-friendliness of the information emergency call system in that a particularly good arrangement and function of the display elements for the functionality of the column and for answering the question of whether a given emergency call has been heard is ensured .
  • This can be done, on the one hand, by arranging around the actuating elements designed as pushbuttons in each case a display element designed as a light-emitting diode ring, which, with a monitoring circuit arranged in the information emergency call column, determines the functionality of the information emergency call column an operating voltage is supplied so that this LED ring lights up and indicates to the user that the column is functional.
  • a second light-emitting diode ring can even be arranged on each of the pushbutton switches, which may light up in a different color and to which an operating voltage is then supplied if, after sending an emergency call or an information request call, an acknowledgment signal issued by the central interrogation point is sent to the information Emergency column has arrived. The user can then safely recognize that the call made has been recognized at the central call point. An acoustic call signal can then also be emitted. Furthermore, an illumination field can be arranged in the upper part of the information emergency column, which also lights up when the information emergency column is functional, as determined by the monitoring device. It can also be provided that the lighting field and / or the corresponding light-emitting diode ring on the pushbutton switch is switched to flashing when an emergency call is made or acknowledged.
  • Another basic idea of the invention is to design the information emergency call system in such a way that a surveillance video camera is connected to all or certain information emergency call pillars via a connection which can be controlled from the central interrogation point.
  • the environment of the information emergency column can then be observed, in particular when an emergency call is made from the central interrogation point which is also an advantage for the detection of blind alarms.
  • all or a certain group of the connected information emergency call pillars are controlled from the central interrogation point into a circuit state in which only the loudspeaker circuit of the respective information emergency call pillars is switched on. General announcements can then be made in this circuit state. It is provided that in this circuit state the microphones of the relevant information emergency call pillars remain switched off, so that constant monitoring or listening to the surroundings of the information emergency call pillars is not possible. In this case, the microphones are only switched on when an emergency call or an information request call is made on an emergency call pillar.
  • the information emergency call system can be designed in such a way that all of its functions are continuously monitored and failures are immediately reported to the central request point.
  • the information emergency call system shown in Fig. 1 has a central office Z with a central cabinet 1, in which the electronic circuits for the control and connection technology are arranged in the central unit in individual inserts, and a main computer, through which the central control and monitoring of the entire system and which is provided with a modifiable programming This technology also enables subsequent changes or extensions to the system.
  • a telephone 2 with a general control panel and a monitor 3, a recording device 4 and a printer 5 are installed in the central station Z.
  • a larger number of information emergency call pillars INS 1, INS 2, INS 16 are connected to the central station Z via lines which are labeled "Line 1", "Line 2", etc., only a few of which are shown for reasons of clarity are.
  • There are Several information emergency call pillars are connected to a line in the manner of a party line, and each line contains three line pairs, the function of which is explained below.
  • Fig. 2 shows an example of the information emergency column INS 1 in a view from the front of the control panel.
  • the information emergency pillar INS 1 has a housing 6, in which the electronic circuits of the pillar described below are arranged.
  • a grating-like opening 6.3 and a further grating-like opening 6.4 are provided in the front panel 6.2 of the housing 6 containing the control panel.
  • a speaker and a microphone are arranged behind these openings in the manner described below.
  • three actuating elements 7, 8 and 9 are arranged in the front plate 6.2, which are designed as push buttons.
  • the pushbutton switch 7 is used to make an emergency call
  • the pushbutton switch 8 is used to make an information request call
  • Each of the pushbutton switches has at least one display element in the form of a light-emitting diode ring 7.1, 8.1 and 9.1, the function of which is explained in more detail below.
  • the housing of the information emergency call pillar INS 1 stands on a base plate 6.1 and has a light field 10 in its upper part, the function of which is also explained below.
  • FIG. 3 shows a basic circuit diagram of the electronic equipment of the information emergency call columns of the system according to FIG. 1 using the example of the column INS 1.
  • each column there is a microcomputer with a modem 11 which controls the functional and monitoring processes taking place in the column.
  • the electronic circuits of the column are connected to the central interrogation point Z shown in FIG. 1 via three line pairs a / Eb / E, a / Sb / S and a / Db / D.
  • the first pair of lines a / Eb / E is connected via a transmitter U1 and a receiving amplifier 14 to a loudspeaker 15 which is arranged in the emergency call column behind the opening 6.3 in the front plate 6.2.
  • the voice signals sent from the central interrogation point to the information emergency column are transmitted via the first line pair a / Eb / E.
  • the second line pair a / Sb / S is connected to two microphones 17 and 18 via a transformer U2 and a transmission amplifier 16 and switching elements 19 and 20.
  • the microphone 17 is located in the information emergency column behind the opening 6.4 in the front panel 6.2, while the microphone 18 is arranged in a manner not shown directly on the push button switch 9, so that a wheelchair user or a child can speak directly into this microphone .
  • the second pair of lines a / Sb / S thus serves to transmit the voice signals that run from the microphones 17 or 18 to the central interrogation point.
  • the switching on of the microphones 17 or 18 or their connection to the transmitter amplifier 16 takes place via electronic switching devices 19 and 20, each after which of the buttons 7, 8 or 9 is actuated, switched by the microcomputer 11.
  • the DC supply voltage for the electronic circuits of the column is simultaneously supplied from the central request point, with the polarity + running over the first line pair and the polarity - over the second line pair.
  • the DC supply voltage is fed to a DC-DC converter 12 and from there forwarded to the individual circuit parts.
  • the supplied DC supply voltage is detected by monitoring devices 13.1 and 13.2, which are connected to the microcomputer 11 and trigger alarm functions there as soon as an interruption in the DC supply voltage occurs.
  • the third line pair a / D-b / D is connected to the microcomputer 11 via a transformer U 3. Control signals in the form of data signals are transmitted in both directions between the central interrogation point and the information emergency column via this line pair.
  • the control for the illuminated field 10 in the upper region of the column is also connected to the microcomputer 11 via an electronic relay 21 and is supplied with the necessary operating current on site via a current source 22.
  • a surveillance video camera can be connected to the column via an output, which is connected to the microcomputer 11 by means of a remote control relay 23, the images of which can be transmitted to the central interrogation point via a special line (not shown).
  • an additional, not shown, light-emitting diode ring on this key can light up in a different color if necessary.
  • a call tone sounds and the light field 10 is switched from permanent light to flashing light.
  • the call tone is switched off and the direct speech connection is switched through on the one hand to the loudspeaker 15 and on the other hand to the microphone 17. This switching does not require any further operation on the information emergency column. It is an intercom connection, ie loudspeaker and microphone are active at the same time. At the end of the call, the connection must be deleted from the central call point. The information emergency column then switches back to the operational idle state.
  • the functional sequence also corresponds to that after the pushbutton switch 7 has been actuated, but there is also a switchover to the microphone 18 which is built into the pushbutton switch 9.
  • the speech height is thus adapted to a wheelchair user.
  • the column can be switched on from the central interrogation point in order to make an announcement.
  • the voice connection is only active in the direction from the central interrogation point to the information emergency column. So it can Announcements can be made without listening to the surroundings of the column.
  • the speech connection is switched through in both directions only when addressed passers-by press one of the push buttons 7, 8 or 9.
  • the remote activation of the column can be signaled by the flashing light of the illuminated field 10.
