Radio system for reporting of loss events

The invention relates to a system for reporting adverse events, such as burglaries, fires, vandalism events, the system being designed to report the occurrence of damage events via radio networks, in particular via telephone radio networks, using frequencies and radio programs of mobile radio techniques and is designed to automatically search for a smooth frequency for single frequency interference.

In the reporting of loss events, in particular burglaries, thefts of motor vehicles, and the like, it is known that the occurrence of loss events occurs to the relevant local exchange via radio networks, especially telephone radio networks present. In this way, priority is given to reducing the costs incurred in establishing loss-reporting systems provided by radio networks, in particular modern mobile radio networks.

For example, such reporting systems may use Nokia's ACTIONET. All that is required is the ability to transmit data through the control channels to which the data of the alarm processing devices are loaded.

From patent application WO / 05553, a reporting system is known which essentially corresponds to the reporting system to which the invention relates. This well-known reporting system is connected to a wired telephone network. It is not protected against vandalism or theft, as is the alarm reporting unit. Accordingly, the object of the invention is to provide a system for reporting adverse events, which is itself protected from vandalism and theft.

The task is solved by having a security alarm reporting system in a protected embodiment for multiple controlled objects, which can be reported by alarm transmitters using conventional sensors for reporting events such as glass breakage, displacement sensors (on motor vehicles, fire alarms and the like, whereby alarm processing devices can be queried for their readiness to function at a predetermined rhythm adapted to the transmission potential, and alarm handling devices made safely against sabotage and have a trench-proof steel trench in the shape of an IP20 metal enclosure for wall mounting, the enclosure having cable glands via rubber nozzles with tensile relief and a contact contact with the cover due to warnings when opening a device whose supply voltage is optionally changed 230 V or 12 V DC, but also have an emergency power supply and operating mode for standby.

U.S. Pat. No. 5,247,564 discloses a wireless motor vehicle reporting system that communicates an alarm to a control panel. However, there are no permanent installations for processing alarms for several objects in a design that is safe from theft or vandalism. The same applies to the system described in EP 0 574 200 Al.

External alarm processing devices in which group signals are emitted from alarm transmitters consist of microcontroller units with multiplexed digital input / output and a radio modem. The problems that arise with such a large number of external alarm processing devices, whose signals must be transmitted over a small number of frequencies, are solved in the same way as with the mobile telephony network. That is, if an event occurs, the alarm processing facility at the switchboard is activated. If any frequency is free, then it is assigned to this preparation. However, if, for example, no frequency is free, this device is put in the waiting loop by the switchboard and given the next free frequency. In this way, none of them is lost in the flood of notifications.

External alarm evaluation devices are designed to operate with conventional sensors for reporting adverse events through distributed alarm transmitters. Distributed alarm transmitters provide potential alarm contact for preparation for alarm reporting. Electronic alarm transmitters can only be used through signal transducers because signals from external alarm transmitters and key switches are taken in the multiplex.

An external device for processing alarms via separate lines supplies the slave alarm transmitters with supply voltage. Preferably, two reporting lines are provided per housing unit. Delayed message line 1 triggers an alarm, such as when breaking glass. The answering line 2 triggers an alarm with a delay of, for example, a time interval of 30 seconds after the house door is opened. This is intended to enable the user to deactivate the preparation via a key switch.

All external devices for alarm processing are checked at the control panel during the operation of the broadcast call, that is, cyclically, whether the radio connection is OK and the device is reporting correctly. It takes a maximum of 2 seconds to set up the connection, transmit data, and disconnect one alarm device. If there is an attempt to sabotage any of the external data processing devices, an alarm is triggered for each query cycle in the control panel. As a cycle time, depending on the number of outsiders, it turns out to be minutes to a maximum of 1.5 hours.

If alarms are accumulated, the appropriate alarm processing devices shall be reported to the control panel and processed in the order in which they are due. So even then there is no loss of notifications.

As a rule, external data processing devices are powered by mains power. In addition, the external alarm evaluation devices are equipped with their own battery, which ensures continuous operation for about two hours in the event of a power failure. Therefore, a buffer battery of 12 V and 6.5 Ah is included in each preparation - basic and expansion device. Preferably, the network connection parts in the devices are expanded with a circuit for maintaining the charge and provide maintenance-free operation of the devices. The batteries are further preferably equipped with a charge control that automatically forms a telegram in the control panel when the capacity of the battery is exhausted. This results in a very secure and reliable system.

The invention is explained in more detail with the aid of drawings, from which further features of the invention can be understood as well as from the sub-claims. The drawings are provided with information on the performance of the components presented. Simatic is the registered trademark of the applicant and indicates programmable memory control. In this, FIG. 1 is a view through the burglar alarm device, FIG. 2 is an apparatus for processing alarms for a multi-family house; 3 is a basic preparation, FIG. 4 is an extension apparatus and the like; 5 building of reception center.

A burglary or theft reporting system comprises a central reporting site with a processing terminal and a reporting printer as well as a radio station designed for, for example, 5,000 alarms and configurable by customers, such as city government, police department, and the like, and can be expanded to a size of 10,000 units (LI, ..., L10000 lines) (receiving control panel includes KF terminal, SE transmitters, SS transmitter control circuit, ACTIONET SK system console, BK console, SER server, printer DR, simatic circuit SI).

Alarm processing devices shall be located either stationary in residential homes or similar places or mobile in motor vehicles. The transmission of the alarm is via a radio modem, for example, providing one basic preparation for up to three residential units. Expansion arrangements for each of the eight residential units can also be presented, as well as independently configured by customers

The interconnection of the reporting site with the alarm processing facility is via radio connections, for example at a frequency of 410 MHz to 430 MHz, for example on Nokia's ACTIONET system. Other standard frequencies and systems may also be used. For example, such a system exhibits four control channels with automatic switching to the data channel of the interrupters. Monitoring of the alarm processing devices in the operational view is possible by cycling the clock or minute rhythm as previously stated.

Basic GG preparation (includes microprocessor μΡ, SSE interface for M expansion modules, SE transceiver; data streams are marked with YES), ie AA preparation for alarm processing (for up to 35 residential units WE1, ..., WE35 per station ), exhibits an IP20 metal housing for wall mounting. The metal housing has cable entries through the rubber nozzles with tension relief and a reporting contact on the warning cover when opening the device. The supply voltage (PSU power supply is designed for 60 VA, also has an external ext Ver power supply) is optionally 230V AC or 12V DC.

The FM radio modem for alarm preparation has a connection module, somehow for three housing units, with a key switch and further three LEDs and an alarm detector input for delayed transmitted alarms as well as an alarm detector input for delayed transmitted alarms.

Furthermore, synchronous sequential SSE interfaces are provided for the connection of up to four EGI, ..., EG4 extension devices, as well as a service interface for start-up and maintenance assistance. The basic setup also shows the self-configuring of the extension devices (they include the SSGM interface for connecting the base module, the output-input module M 'and the PSU' power supply for 10 VA, also intended for external ext Ver power supply).

The processing device for the extension device also has an IP 20 - metal wall mount housing with cable gland via a rubber mount with tension relief and a reporting contact on the warning cover when opening the device. It is also designed as a basic device, and additionally comes an interface for connection to the basic device.

The mobile alarm system also features an IP 20 metal housing for motor vehicle mounting, with cable entries through rubber mounts with tension relief and reporting contact with the warning cover when opening the device. Power is provided by 12 V DC for a power consumption of about 5 A - for about 2 s - in transmitter operation and with a maximum of 1 A - including heating - in standby mode. Heating is provided as an integrated heating device. The radio modem is executed just as with the on-site preparations. The alarm processing device also has a service interface for startup and maintenance assistance and is designed for a temperature range of -40 ° to + 50 °. Its electronics are capable of being used in motor vehicles, that is to say, it is safely executed for shocks and disturbances.

The modular structure described previously, using external expansion modules, results in a compact design and small size for uniquely designed hardware for all external components. The electronics are optimized in terms of price because they only carry out the truly necessary functions and all components - except the radio modem - can be installed in a single unit. The multiplexing technique also contributes to this.

Preferably, the extension modules can be up to 100 m away from the basic device, so that the installation of the extension devices can be carried out close to residential units and with low cable consumption. Self-configuring the expansion modules is especially preferred, i.e. addressing is done automatically. Therefore, the local installer only needs to connect the cable. Using the service interface, fault detection is quick and easy, for example through a mobile terminal.

It is also particularly advantageous that the new system according to the invention be independent of the local current network for at least a limited time. Therefore, it is largely safe from sabotage. The housing made of sheet steel also contributes to this.
