Remote current sensor monitoring system and GPS tracking system and method for mechanized irrigation systems

A wireless interface remote monitoring system for self-propelled irrigation systems (center pivot and lateral move sprinklers) includes a remote terminal unit (RTU) mounted on an outer drive tower of the irrigation system. The RTU includes a radio transceiver capable of sending and receiving data packets over a satellite or terrestrial telemetry backbone to and from a central control computer. The RTU further includes a current sensor and a GPS receiver both for detecting movement or non-movement of the sprinkler, a microprocessor with nonvolatile memory for storing current data and GPS coordinate data from readings taken in series over time, and a pressure or flow sensor for detecting the presence or absence of water flow at the outer drive tower of the sprinkler. The current sensor connected between the RTU and a tower drive motor, allows the RTU to calculate the “movement” or “non-movement” of the irrigation system over a specified time period. Redundantly, the GPS receiver records changes in position to indicate movement or non-movement within the GPS error tolerance. Once a change from movement to non-movement or vice-versa is determined, the RTU transmits the data by satellite or radio telemetry to a central control computer which logs the movement or non-movement of the monitored drive tower, the GPS coordinate data and the water status readings, all with time and date stamp. The central control computer creates “page message” and “text message” updates as necessary on the status of individual irrigation systems and “groups” of irrigation systems that are in turn delivered to wireless devices and computers for sprinkler operators.

Automatic cleaning treatment method and automatic cleaning treatment system of air-conditioning heat exchanger

The invention discloses an automatic cleaning treatment method and an automatic cleaning treatment system of an air-conditioning heat exchanger. The automatic cleaning treatment method comprises the following steps: after an air-conditioner is started, judging whether the starting condition of automatic cleaning treatment of the air-conditioning heat exchanger is met; if yes, starting the refrigerating mode of the air-conditioner to enable surface of the heat exchanger to frost, and judging whether frosting is finished; after the frosting is finished, controlling the refrigerating mode of the air-conditioner to turn off, starting the air supply mode, then, starting an indoor draught fan to enable frost on the surface of the indoor heat exchanger to melt to water, and judging whether defrosting is finished; and after the defrosting is finished, controlling the heating mode of the air-conditioner to start, drying the heat exchanger, and ending cleaning. According to the invention, the inner side heat exchanger frosts after the temperature is rapidly decreased and covers and wraps dust and germs during frosting, the dust and germs on the heat exchangers are rapidly discharged along with water flow of a large quantity of defrosting water generated during the defrosting process, and automatic cleaning is realized through redrying treatment.

Method and apparatus for producting negative and positive oxidative reductive potential (orp) water

ActiveUS20050121334A1Effective and efficient and economicalCellsWater treatment parameter controlParticulatesElectrolysis
A method and apparatus for electrolytically producing oxidation reduction potential water from aqueous salt solutions for use in disinfection, sterilization, decontamination, wound cleansing. The apparatus includes an electrolysis unit having a three-compartment cell (22) comprising a cathode chamber (18), an anode chamber (16), and a saline solution chamber (20) interposed between the anode and cathod chambers. Two communicating (24, 26) membranes separate the three chambers. The center chamber includes a fluid flow inlet (21a) and outlet (21b) and contains insulative material that ensures direct voltage potential does not travel through the chamber. A supply of water flows through the cathode and anode chambers at the respective sides of the saline chamber. Saline solution flows through the center chamber, either by circulating a pre-prepared aqueous solution containing ionic species, or, alternatively, by circulating pure water or an aqueous solution of, e.g., aqueous hydrogen chloride and ammonium hydroxide, over particulate insulative material coated with a solid electrolyte. Electrical current is provided to the communicating membranes separating the chambers, thus causing an electrolytic reaction that produces both oxidative (positive) and reductive (negative) ORP water.

Method for re-cycling wellbore cuttings

A method for remediating cuttings from a wellbore has been invented which, in certain aspects, includes transporting a system for remediating the cuttings to an offshore rig in transportable containers, the system including a thermal treatment system and a condensing system; feeding a slurry of the cuttings with oil and water to the thermal treatment system and heating the cuttings therein producing heated cuttings an a stream with oil and water; discharging the heated cuttings from the thermal treatment; feeding the stream with oil and water to a condenser system producing a liquid stream; and feeding the liquid stream to an oil/water separator producing an oil stream and a water stream. In another method for remediating cuttings according to the present invention, the method includes feeding a slurry of the cuttings with oil, fine particulates, and water to a thermal treatment system and heating the cuttings therein producing heated cuttings and a stream with oil and water, discharging the heated cuttings from the thermal treatment, feeding the stream with oil and water to the filter system, filtering out fine particulates from the stream with oil and water, feeding the stream with oil and water to a condenser system producing a liquid stream, and feeding the liquid stream to an oil/water separator producing an oil stream and a water stream.
