Definitions

  • the storm water may be filtered when entering the storm drain or when resident within the storm drain, in order to reduce the amount of pollutants in the storm water.
  • Another strategy is to lead the storm water to a purifying plant where the storm water is purified generally using different mechanical and chemical purifying steps.
  • Yet another strategy is to filter the storm water in the storm drain and subsequently lead the storm water to a purifying plant for a second subsequent cleaning.
  • a sudden discharge of a pollutant into the storm drain may damage the filter device resident within the storm drain.
  • a purifying plant connected to the storm drain concerned may become damaged if subjected to a sudden and/or considerable discharge of a pollutant.
  • any sudden discharge of a pollutant into the storm drain may result in that the capacity of the filter resident in the storm drain is insufficient, thus allowing polluted storm water to leave the storm drain unfiltered or at least unsatisfactory filtered.
  • Another problem is that, as the filter resident in the storm drain becomes saturated with pollutants, other objects or substances present in the storm water, the efficiency of the filter becomes reduced. As the filter becomes saturated the percolation capacity of the filter may also become reduced. As the percolation capacity of the filter is decreasing, the function of the storm drain may be affected, as the storm drain might no longer be able to receive the required amount of storm water per unit time, due to the reduced percolation capacity of the filter. This condition of insufficient percolation capacity may lead to flooding or undesired discharge of pollutions as the storm drain is no longer capable of receiving a required amount of storm water.
  • sensor any type of device or entity being capable of sensing a condition of any kind in the storm drain.
  • a sensor may for instance be configured to determine or sense a physical quantity such as the temperature or humidity in the storm drain, but may also be configured to determine e.g. the presence of a substance in the storm drain.
  • a sensor may be configured to determine e.g. a pressure or a flow. Consequently, depending on what is to be determined, various kinds of sensors may be employed.
  • the sensor or sensors in the storm drain are arranged in communication with or connected to a sub node. By arranging the sensors in communication with the sub node, information regarding the conditions as determined by the sensors may be transmitted to the sub node.
  • connection may be a physical galvanic connection, e.g. realized by means of conductive wires.
  • the connection may alternatively be any type of wireless connection based on radio frequency communications or any other suitable wireless technology, such as an optical connection, an acoustic connection, an inductive connection or the like.
  • sub node is to be interpreted as any device or entity being capable of receiving data from a sensor and transmitting data to a second entity, such as a main node. Further, the sub node may employ capabilities of processing the data received from the sensor. For instance, the sub node may convert the data from an analog format to a digital format or vice versa. The sub node may also compress, modulate, encrypt or in any other way alter the data received from the sensor.
  • data is meant any representation of information, analog or digital. Further, the data may be, compressed, modulated, encrypted or modified in any other way depending on the needs of the actual application in question.
  • main node is to be interpret as any device being capable of receiving data from a second entity, such as a sensor or a sub node, to which second entity the main node has been arranged in communication. Further, the main node may employ capabilities of processing the data received, e.g. in order monitor an environmental condition of a storm drain. For that reason the main node may be employed with a central processing unit, CPU, or similar. The CPU of the main node may run one of several programs for e.g. monitoring an environmental condition in the storm drain. The main node may convert the data from an analog format to a digital format or vice versa. The main node may also compress, modulate, encrypt or in any other way alter the data received. The main node may further comprise storage capabilities such as a hard drive, a memory card or any other type of volatile or non-volatile memory being capable of storing data.
  • the at least one sensor may be arranged in communication with the sub node by means of a radio frequency connection.
  • a radio frequency connection By arranging the sensor in communication with the sub node by means of a radio frequency connection, the sub node and the sensor may be located remote from one another without the need of installing any physical connection between the sensor and the sub node. Further, the use of a radio frequency connection requires no line of sight between the sensor and the sub node. The use of a radio frequency connection is thus advantageous in that the installation becomes easy and at the same time insensitive to the relative positioning of the sensor and the sub node.
  • the at least one sensor may be arranged on the filter unit of the filter device, on the floating carrier of the filter device, or in the storm drain in a position separate from the filter device. This is advantageous in that the position of the sensor may be altered depending on the need.
  • the sensor By arranging the sensor on the filter unit of the filter device, physical quantities related to the filter unit may be measured, as the sensor is brought in contact with the filter unit. In addition to the above, the sensor may easily be exchanged or inspected when exchanging the filter unit.
  • the sensor may be exchanged or inspected when exchanging or inspecting the floating carrier.
  • the senor may be arranged in any other position in the storm drain, such as in the storm water present in the catch basin or in the air filled vertical pipe above the filter device.
  • the arrangement of the sensor in question will depend on the condition to be measured, meaning that the sensor may be arranged in a, for the particular application, favorable position in the storm drain.
  • the at least one sensor may be chosen from the group consisting of: a pressure sensor, a flow sensor, a temperature sensor, a humidity sensor, a light sensor, a gas sensor, a carbon dioxide sensor, an acceleration sensor, a hydro carbon sensor, an electrical field distribution sensor and an electrical field penetration sensor. This is advantageous in that a sensor suitable for the current need may be chosen.
  • the sub node may be arranged in communication with the main node by means of a radio frequency connection.
  • a radio frequency connection exhibits several advantages, as discussed above.
  • the main node may be arranged in communication with at least one external sensor arranged outside the storm drain for determining an environmental condition outside the storm drain, the communication being direct from the external sensor outside the storm drain to the main node or indirect to the main node by means of a sub node.
  • an external sensor outside the storm drain By arranging an external sensor outside the storm drain, an environmental condition outside the storm drain may be determined.
  • conclusions regarding conditions external to the storm drain may be drawn, such as the weather, the temperature, the light conditions or precipitation. The conclusions drawn may then be used as a basis for monitoring an environmental condition in the storm drain.
  • data from the external sensor outside the storm drain may be transmitted to the main node, where it may for example be stored, processed or transmitted further.
  • the at least one external sensor arranged outside the storm drain may be chosen from the group consisting of: a temperature sensor, an oxygen sensor, a carbon dioxide sensor, a moisture sensor, a light sensor, an acceleration sensor and a combustion gas sensor. This is advantageous in that a sensor suitable for the current need may be chosen.
  • the main node may be arranged in communication with at least one remote resource, which is advantageous in that the main node may communicate with and transmit data to and/or receive data from the remote resource.
  • the wording "remote resource" is to be interpret as any remotely located resource with which the main node may communicate.
  • the remote resource may for example be a server or several servers located remote from the main node.
  • the remote resource may be a data base which is updated or complemented by data transmitted from the main node.
  • the remote resource may be a database from which the main node may retrieve data.
