Abstract

The procedure involves telephone subscriber:s appts. with two memories for numbers and timing modules (ZM,Z1,Z2), a VHF radio remote control with a key and receiver, a 24-hour module, a battery with voltage regulator and charger, a mains outage unit, a stabilised power supply and a heavy-current relay. On receipt of a call for help, the system manager can read the telephone number of its source and communicate with it from any fixed or mobile telephone. ADVANTAGE - Both the service operator and the user benefit from a highly mobile emergency call acceptance station which can identify callers without recourse to fixed terminals and wiring.

Description

The invention relates to a method for transmission of emergency calls from people in need of help after the Preamble of the claims.

Procedures for transmitting emergency calls are from the euro European patent application 21 425 and from the patent document DE 31 37 147 C1 known.

The known methods have the disadvantage that on the Receiver side (emergency call center) "wired" terminals (usually MODEM and private additional facilities on public long distance network and a personal computer) can be installed need to identify the emergency participant with him To be able to contact and arrange appropriate help to be able to.

This makes for a round-the-clock occupation of the House emergency call centers necessary.  

Because after an emergency call, often a force of the service provider rushes to the help seeking participant to provide help or to hand over the front door key to the emergency services give and since this force with the dispatcher of the Home emergency call center cannot be identical, otherwise the House emergency call center would no longer be manned, would have to such a process can even hold 2 forces. In any case, a not insignificant personnel expenditure necessary (note also Sundays and public holidays) to the Ensure 24-hour presence, which causes high costs.

These costs are either apportioned to the user or Often, this leads to the installation of a home emergency call systems must be dispensed with, although the customer potential remains would be there.

On the other hand, aid organizations hold and also private institutions provide mobile background services (e.g. the head of operations on duty) who the task of a house emergency call center could take over, provided the technical Prerequisites can be created.

In the described method - claims - there is Receiver device from a city call receiver numerics with the known dimensions (approx. 4X 3cm).

The advantage of this highly mobile control center is that the dispatcher on duty can move freely and thus Can carry out multiple activities.

So it is with the system described z. B. possible that a head of operations from the service of an aid organization also the The task of the house emergency call center can take over without being on site to be bound.

Since a numeric city call receiver has 1 numeric destination and 2 sound-only destinations, the city call receiver can not only be used to receive house emergency calls (numeric destination), but also for other destination calls (e.g. 2 destination-only tone: call back to the emergency center; 3 Destination call tone only: call back at the service station).

The method described - claims - thus carries makes a significant contribution to reducing costs and makes it special installing a house in smaller catchment areas emergency call system at affordable prices for the user only possible.

Another useful application example would be in the area of social services to see.

In this way, particularly vulnerable people in need of care, a house emergency call device claims as described above receive.

The receiving device (city call receiver numerics) receives the service having a nurse.

If help is needed, it confirms the radio finger. The city call recipient of the sister on duty strikes the nurse recognizes which patient is helping on the diplay needs and visits this patient.  

The system is described below.

The system consists of the system components:

• - Telephone unit with 2 memory locations for Storage of telephone numbers and hands-free system -Time modules ZM, Z1 and Z2.

These are time modules with known technology that after applying an operating voltage a one-time realize adjustable pull-in or drop-out delay and after a voltage drop (interruption of operating voltage) in the Go original state.

• - VHF radio remote control with radio finger and receiver unit
• - 24 hour module
• - Lead acid battery with regulator and charger
• - power failure unit
• - Power supply with stabilization device
• - Power switch relay (SAR).

An emergency call is triggered via the VHF radio finger the time relay Z1 switches in the radio receiver unit. It is a delayed release relay.

The contacts z1 to z3 go into work and result in:

• - z1 in progress activates the time module ZM <Zm1 contact bridges the memory button 1 <.

The telephone set takes up an office and dials the city call center of the Deutsche Bundespost - Telekom. ZM1 has a drop delay of approx. 1.5 seconds.

• - z12 in progress activates the time module Z2 <Delayed on, the Z2 relay goes into operation and the z21 contact bridges the memory key 2 in the telephone set unit <The subscriber identification (in DTMF dialing) and 2X pound key press is given to the telephone line. The time of the delay in the arrival of Z2 depends on the length of the first part of the announcement text of the city call computer of the Deutsche Bundespost-Telekom ("City call, you have dialed the radio call number...") And can be entered with 23 seconds.

The city call is sent.

• - z13 contact switches the time relay z3 active <after one Time of t = 35 sec (alarm completed) switches on z31 contact the power switch relay S1 to the Amtsleitg.
• - The city call recipient at the dispatcher strikes and and the subscriber ID appears on the display of the Numeric receiver
• - The dispatcher calls the participant:
• - The power switch relay is activated, the s1 contact bridges the handsfree key in the Telephone unit <subscriber loop <communication between dispatcher and participant is established.
• - After a time of t = 3 minutes, the Z1 relay drops out and the Original state is created.

Options

Optionally, the device with a 24 hour clock and / or with a gas detector in a known mode of operation be prepared.

The working contacts of these institutions would then cause the Z1 relay to tighten.

The emergency call can also be triggered on the device or on external emergency triggers.

The working contacts of these institutions would then cause the Z1 relay to tighten.

Power failure

In the event of a power failure, there is a power failure relay and a battery with charge monitoring and controller in a well-known Working method available.
