Microwave intruder-alarm system for safety-supervision of extended and complex facilities.

Kurzfassung

A Hungarian state medium size company developed an intruder-alarm system for security-supervision of extended and complex facilities. Main advantage: high reliability and continuous operation. The technology is suitable for military, industrial facilities, airport, agricultural area, power plant and oil refinery operators. The company seeks servicing partners for further technical development tasks or for commercial tasks with technical consultancy and antenna manufacturing.

Details

The Hungarian company deals with defence industrial products (fire control, radars, etc. repairing, testing and development), manufacturing and installation of safety-technology systems (H-field detector, microwave sensors, signal processing centres and their software), and development, manufacturing and distribution of satellite remote surveillance systems (eg. vehicle-fleet follow-up system).

The company's H-field sensor technology is based on the following principle: a person moving in microwave space generates amplitude- and phase-modulation due to the reflected waves. Amplitude modulation depends on the movement speed and movement direction of intruder. Amplitude modulation: information can be added to several methods to carrying frequency, one method is the change of signal amplitude. The amplitude modulation is described in percent. If there is no modulation it is 0%, if fluctuates between 0 and maximum, it is 100%. Phase modulation: change of high frequency electromagnetic waves phase-degree according to the electronic form of information requested to be sent.

By the process the penetration to enclosed strip sector can be sensed and signed with the opposite side sited transmitter-receiver. The outdoor intruder-sensor signs are processed by signal processing centres. In extended and complex facilities these systems work as sub-centres and co-operate with main computer centre. To reduce possibilities of false alarms the sectorial installed sensors can be organised to logical groups. All defensive sections can be handled independently. Printer can be connected to computer and automatically recorded events can be printed.

The power source is a battery (continuously charged from network) so in case of interruption of electricity supply the system remains serviceable. The signal processing system has modular structure, so it can be supplemented later. Design: protected against sabotage

Software characteristic:

• Provides visual information about the whole system, subsystems and defensive sectors.
• Contains arrangement list regarded to defensive sectors
• Signs handled according to priority sequence
• Records the last 10.000 incident
• Reliably identify the authorisation of technology treater (fingerprint checking with mouse connection or by card authorisation).

Innovative Aspects:
Innovation of the technology: exceptionally reliability. Other products available in market are made for civil purposes, the company's technology basically developed for military purposes.

Advantages of company's technology:

• Adjustable by computer: can be adjusted to environment at installation and operating (easily configurable).
• Reliable operation in rain and snow.
• Easily repairable.
• Cost-efficient.
