Outdoor Security System

This is the first outdoor security system that requires no electricity. It uses sensors and trap sensors to detect intruders and risk situations. With no need for building works or channelling, since the technology it uses is completely cordless.

The system cosists of an electronic unit and a number of sensors and trap sensors (three different types) plus, if neccesary, an actuator with up to 50 components per installation. The coverage range can be up to 50 metres between each trap sensor and the Electronics Unit. Remote communications are achieved by using a SIM card from any operator, slotted into the Electronics Unit. Optimal power management means that the system can send one alarm every day for a whole year.

Trap sensors for detecting people

With conventional security a large number of electronic devices are used, but they're not traps. They are detectors that make no attempt to be hidden: barriers, cameras, volumetric devices, etc. Burglars are aware of their existence and so try not to be detected. They are intended to detect intruders in closed compounds.

Our system can detect and surprise intruders anywhere out in the open, applying logic: if someone wants to steal they must pass along a certain path, approach a certain machine, enter a given site, open this box, go up those stairs, etc.

Sensors for risk situations

Issuing an alert if an animal leaves a fenced area, when the water level is too low or too high, when somewhere is flooded, if there is a power outage, or for any other application without the need for a power supply.

Applications

For tracks, fencing, gates, farm machinery, irrigation wells, barns, silos, pens, tools, etc. From now on traps can protect the things that previously were at risk of being stolen or damaged.

Big return in corn

When it came to deciding whether or not to spend $120,000 to install a center pivot in an area where the systems are a rarity, “We had to do some serious thinking,” says John Grant, who farms hill land in north central Mississippi.

John Grant, and his son, Kenneth, say the difference in corn yield over dryland in 2008 helped them pay almost half the cost of installing a center pivot system on a 170-acre field. They’re hoping to recoup the rest of the cost this year.

Drilling wells in the area is an expensive — and often futile — proposition, given the depths required to try and get adequate water to run an irrigation system. Grant and his son, Kenneth, who farms with him, had a go at drilling a well on a field where they planned to grow corn in 2008, but called it quits when they got to 600 feet and still couldn’t get sufficient water to run a center pivot. They weren’t ready to give up on irrigation, though.

“Bogue Creek runs along one edge of the field,” says John. “You can walk across it in most places and not get too wet, and just to look at it, you wouldn’t think there’s enough water flow to support a quarter-mile center pivot. But, it doesn’t go dry in the summer, and when we checked the flow, it averaged 3,000 gallons per minute. The pivot would require only 1,000 gallons per minute.

“We worked with the Big D folks at Greenwood, Miss., to design a Valley system that would pump water from the creek, uphill through an underground line, to the pivot". “We had to pay the electric company $9,600 to run a line to power the pump in the creek and the pivot, but when we looked at operating costs, electricity was much less than diesel.

“We ran the system 16 days last year, and we’ve already used it several times this season. It takes 36 hours to make a full circle on 167 acres, putting down a half-inch of water.”

When harvest time came, says John, any reservations they may have had about the irrigation investment vanished. “We averaged 195 bushels on the field, and the yield monitor on the combine was showing some spots with 230 bushels. On areas outside the pivot, we averaged 54 bushels. With the price we got for our corn, we figure we recouped half the cost of the system in just one year". “If corn prices hold this year, and we’ve already got a lot of it booked, we’ll likely make back the rest of what it cost us. As soon as we get this pivot paid for, we’ll look at putting in another.”

Vehicle collides with Pivot Irrigation System

State police are looking for the driver of a vehicle who fled after colliding with a Pivot irrigation system southwest of Bridgeville.
Police say a faulty stop arm on the irrigation system – a large metal structure more than a thousand feet long that moves on wheels around a central pivot point to water farm crops – placed it onto Cannon Road between Wesley Church Road and Federalsburg Road, where it was struck by the car traveling east about 2:45 a.m.
The collision left both the vehicle and the irrigation structure inoperable. The occupants fled after removing the license plates from the vehicle, police said.
They said there was no sign anyone was injured. The pivot had to be removed from the vehicle by a towing company, which then removed the vehicle.
The Bridgeville Fire Department and the De Department of Natural Resources and Environmental Control responded to remove hydraulic fluid that spilled onto the road. The road was closed for about two hours.

Installation of 23 Center Pivot in Pakistán

The Government of Sindh intends to install 23 Center Pivot Toeable Sprinkler Irrigation Systems, one each of 50 acres, at each district of the province. The list of districts: Hyderabad, Karachi, Thatta, Matiari, Jamshoro, Dadu, Badin, Mirpurkhas, Sanghar, Tando Mohd Khan, Tando Allah Yar, Umer Kot, Nawabshah (Daur), Naushehro Feroze, Khairpur (Nara), Tharparkar, Larkana, Ghotki, Sukkur, Jacobabad, Kambur-Shahdadkot, Kashmore-Kandhkot, Shikarpur.
