Definitions

  • the invention relates to a monitoring system for a district heating distribution network, which is provided with a plurality of control electronics, which are controlled and interrogated by a central unit at the connection points of the district heating distribution network, with a plurality of sensor electronics, the measurement wires of measuring wires inserted into the insulation material of the pipes of the district heating distribution network and / or detect measuring elements.
  • connection points To transmit the heat energy between a district heating distribution network and the heating circuit in each building home stations (connection points) are used, in which the energy exchange between the heating circuit and the district heating circuit via heat exchangers.
  • the control of this process via district heating which is provided with a control electronics.
  • This control electronics can be controlled and queried by a central unit.
  • These regulators have different signal inputs, which can be used to measure different measurands, such as temperatures, and signal outputs, via which pumps and valves are controlled and output via the data to the central unit.
  • the control panel is usually connected to a process visualization, which graphically represents the operating status of the individual controllers and the house stations connected to them.
  • the pipes of a district heating distribution network are regularly provided with measuring leads and / or measuring elements whose measured values are detected by a sensor electronics (see eg DE-3930530).
  • the measurement wires are interconnected to larger monitoring sections and from monitored a continuous monitoring device.
  • Larger networks use centralized systems consisting of a centralized unit and locally distributed meters, each of which monitors specific monitoring sections for moisture and locates the site of damage.
  • the measured value output, the message output as well as the parameterization of the individual devices are carried out from a central device. These central devices are usually equipped with display devices for the graphical representation of the system status and the incoming messages.
  • the invention has for its object to provide a monitoring system for a provided with a controller electronic district heating distribution network, which allows for the absence of a separate transmission system for the measured values of the sensor electronics a simple, accurate localization of a damaged site.
  • each of the sensor electronics for determining the measured values detected by them is set to an electronic controller associated with one of the connection points, and the measuring wires and / or measuring elements extend from the sensor electronics connected thereto to a connection point adjacent to the respective connection point.
  • the measured values transmitted by the sensor electronics to the associated control electronics are preferably the insulation resistance of the thermal insulation, other electrical parameters influenced by moisture in the thermal insulation (voltages, currents in amplitude and / or signal form), or the resistance value of the measuring arm.
  • the measuring elements may be formed as a measuring loop, which is formed by a sensor wire and a scrubluminatader.
  • the district heating distribution network consists of tubes 18, which leads to connection points 10. At the connection points are arranged regulators, which are provided with pumps and / or valves, which are controlled by a controller electronics 14. This controller electronics is controlled and queried by a central unit 12.
  • the monitoring system furthermore has a plurality of sensor electronics 16 which detect measured values of the sensors 20 which consist of measuring leads and / or measuring elements introduced into the insulating material of the tubes 18 of the district heating distribution network 20.
  • Each of the sensor electronics 16 is set up to transmit the measured values acquired by them to the controller electronics 14 associated with the connection point.
  • the sensors 20 extend from the sensor electronics 16 connected to them to a connection point 10 adjacent to the respective connection point 10.
  • the proposed training can be carried out with very simple devices complete monitoring even complex district heating networks.
  • the infrastructure which is already available for the control system (ie for the controllers) is used:
  • a query of the measured values of the sensor electronics that is, e.g. a query of the insulation resistance of the pipe section between the requested controller electronics and the adjacent connection point. Since in each case only relatively short sections are queried, it is also possible to keep a differentiated statement about the network status, for example, to detect multiple errors.
  • a further advantage is that with extensions or densifications of the district heating distribution network increasingly differentiated statement is possible, since the junction of each queried controller electronics and the adjacent junction are known, the respectively queried sensor loop is known.
