Architectural & Engineering Specification For Buried Seismic Detection System 1.0

General performance specifications 1.1

System description

The buried seismic detection system shall function as an electronic perimeter intrusion detector. The system shall be used with / without fences to protect the perimeter of a site. The system shall consist of a series of seismic sensors connected by cables in a row, and a microprocessor-based signal processor. The system shall be capable of detect and classify two types of intrusions – by foot and by vehicle. The sensor shall detect intruders who walk or run. The system shall be capable of functioning as either a standalone system or as an integral part of a centralized control and maintenance facility.

1.2

System technology

The signal processor shall analyze the signals from seismic sensors that detect minute vibrations in ground. The processor shall utilize adaptive algorithms to discriminate between actual, false and nuisance alarms. 1.2.1

Seismic Sensors

The seismic sensors comprise a spring-mounted magnetic mass moving within a wire coil to generate an electrical signal The response of the seismic sensor is proportional to ground velocity The sensors shall generate signals when an attempt is made to dig , walk, run or to drive a vehicle in the area. Signals from the sensors are transferred to an analyzing unit that decides if an alarm is to be generated or not. 1.2.2

Signal processing algorithms

The system shall utilize digital signal processing techniques that employ adaptive algorithms, capable of adapting to soil types environmental conditions. The system should be capable of classifying intrusion to footsteps and vehicles classifications and to set different sensitivity level for each (for example : to filter out vehicles and to detect only footsteps).

1.3

Detection properties

1.3.1

Detection sensitivity

The system shall detect digging and intruders by foot / vehicles while rejecting other environmental stimuli.

False and nuisance alarms

1.3.2.1 System-generated alarms (False alarms) The maximum rate for alarms generated by internal electronic processes (cables excluded) shall be less than one per 1km per year, averaged over the total number of Km in the system. 1.3.2.2 Environmental alarms (Nuisance alarms) The system shall operate within specification in typical outdoor environments. The system shall be installed in accordance with the manufacturer’s recommendations to minimize the probability of alarms from the following factors while maintaining the full detection capability for valid intruders: 

Precipitation including rain, snow, hail and fog



Sunrise/sunset



Winds up to 60 km/h (37 mph)



Temperature changes



Sandstorms



nearby vegetation



nearby sources of radio-frequencies and electro-magnetic interference



acoustic or magnetic effects

1.3.2.3 Notification of environmental concerns Before installation begins, the installer shall alert the customer, in writing, as to all site-specific conditions that may contribute to a higher environmental alarm rate. The customer shall decide whether to remedy the situation or to accept the nuisance alarm sources without any further responsibility on the part of the installer or the manufacturer.

1.4

Sensor characteristics

1.4.1

Sensors Spacing

Two seismic sensors shall be interconnected by 5 to 30 m length of sensor cable. The selected spacing depends on required threats to detect by the client (walking, vehicle, and digging) 1.4.2

Zone length

The maximum length of each zone shall be 20m. Smaller zone lengths can be requested by the client (for better localization if required). 1.4.3

Sensor Line

The sensor line that interconnects the sensors shall be capable of transmitting the detection signals for up 500m to a central unit. Rev A

Performance history

1.5.1

Previous installations

The system shall have been installed and operational for at least 4 years. 1.5.2

Customer references

The vendor shall submit the names and telephone numbers of at least four users who shall serve as references for the satisfactory performance of the equipment. The users shall have a minimum of one year’s performance experience with the equipment.

2.0

Signal processor specifications

2.1

Signal processor description

1- 3 sensors are analyzed by one processor (the processing is done at sensor level and not by comparing adjacent channels). The processor shall operate either as a standalone unit with local alarm relays, or as an integral component of a centralized control and maintenance facility. The processor shall include internal circuitry to protect against lightning and voltage transients.

2.2

Signal processor operation

2.2.1

Distributed processing

The signal processors distributed along the perimeter shall receive and process the signals from the sensor line while providing fail-safe operation. The failure of one processor shall not affect the signal processing of the other processors along the perimeter. 2.2.2

Total sensor length

Total sensor cable length shall be expandable to 500m, and can be extended to an unlimited length using multiple sensors lines. The detection zone shall be continuous and uniform, and there shall be no gap between the individual zones, when installed in accordance with the manufacturer’s recommendations. 2.2.3

Alarm outputs

The signal processor shall identify alarms locally by relay contacts. Alarms caused by walking, running, digging and moving vehicles shall be identified as intrusion alarms. Alarms caused by, power failure, low input voltage, cable fault, or internal electronic fault shall be identified as supervisory alarms. Supervisory alarms shall be distinguished from intrusion alarms.
