  • a practical or convenient connection of the auxiliary electrical power AEP from the vehicle to the auxiliary equipment 20 is thereby established by integrating the electrical connecting interface 34 in the actual docking station 30.
  • the electrical connection interface 34 and the pipe connecting interface 31 is formed as a unit, permitting automatic connection of the auxiliary electrical power AEP when the pipe connection is performed. With such a configuration, the electrical connection will be established without any separate manual maneuvering.
  • the generator 13 delivers nominally 3 kW, 400V AC, and for security reasons the generator 13 is provided with motor protection, load loss and short circuit, as well as a residual current operated circuit-breaker.
  • the auxiliary electrical power AEP is produced by means of a hydraulically driven generator 13 carried onboard the vehicle 10, whereby said hydraulic drive power for the generator will be supplied from a power take-off of a propulsion system of the vehicle 10 in a manner that is obvious to the skilled practitioner and that will therefore not be described in detail herein.
  • the auxiliary electrical power producing generator 13 must also be grounded by means of a grounding line 19 connected to the vehicle 10 through the electrical connecting interface 34.
  • the grounding line from the connecting interface 34 to the vehicle is normally integrated in the supply line 18.1 and has therefore not been specifically illustrated.
  • Fig. 4 is very schematically illustrated the basic principles of a pipe connecting interface 31 for use in the system 1 of the invention.
  • the pipe connecting interface 31 consists of the above mentioned first and second pipe connector elements 32 and 33, respectively.
  • Said connector elements 32, 33 are of any known quick-connection type to be easily mutually connectable to provide a secure, sealed and air-tight connection for the transfer of waste in the air stream produced by the vacuum source 11.
  • Such connector elements are well known within the art and will therefore not be described or illustrated in detail herein.
  • Fig. 4 illustrates the embodiment where the electrical interface 34 is physically integrated in the docking station 30, and likewise only very schematically shows a first connector element 34A connected to the vehicle supported power supply line 18.1 and a second connector element 34B connected to the stationary power line 18.2.
  • Said electrical connector elements 34A and 34B may likewise be of any known quick-connection type and will therefore not be shown or described in detail herein.
  • the electrical connection interface 34 is physically or functionally integrated in the actual pipe connecting interface 31 in the waste pipe docking station 30 for establishing an automatic connection of the supply of auxiliary electrical power AEP from the vehicle to the auxiliary equipment 20.
  • each waste storage tank 3.1; 3.4; 2.2; 2.3; 2.4 in the system 1 is identified so that the generator 13 will be started only when a storage tank 2.2; 2.3; 2.4 requiring auxiliary power is connected for emptying, as was briefly indicated above.
  • FIG. 5 which is a schematical illustration of a storage tank identification arrangement
  • the storage tank identification is performed in the following manner.
  • Each waste storage tank 3.1; 3.4; 2.2; 2.3; 2.4 of the system 1 is conventionally equipped with a tank control box TCB through which several tank control functions are performed in cooperation with a likewise conventional vacuum truck PLC, as is very schematically indicated in FIG. 5 .
  • TCB tank control box
  • the tank control box TCB of each waste storage tank is equipped with an I/O-device 35 having a non-volatile RAM-memory 36, which is a memory that does not loose data when power is switched off.
  • This memory 36 has a default factory value.
  • a control system (not specifically illustrated) in the vacuum truck PLC reads the identification data saved in the I/O-device 35 of the connected waste storage tank. In this way the control system retrieves identification of the currently connected tank. Specifically, the identification numbers are supplied to and retrieved from the respective tank control boxes by the vacuum truck PLC, through a connection line 37 that may be automatically connected through the electrical connecting interface 34 or alternatively through the pipe connecting interface 31 of the respective docking station 30.
  • the vacuum truck PLC control system has identified that a connected waste tank is equipped with an agitator or other equipment requiring auxiliary power, activation of the generator 13 is initiated through a signal line 38. In this manner it is secured that the generator 13 is only started when the vehicle 10 is actually connected to a waste tank requiring auxiliary electric power.
  • Fig. 6A is illustrated an exemplary vacuum fan 40 for use as the vacuum source 11 in the vehicle 10.
  • the vacuum fan 40 comprises a fan housing 41 with an impeller (not shown) rotated by a hydraulic motor 42 that will normally be driven through the vehicle propulsion (likewise not shown).
  • the impeller sucks in air through a fan inlet channel 43 that in the waste collection system application communicates with the vehicle carried waste pipe 12 to create vacuum in said waste pipe and ultimately in a waste storage container 2.2, 2.3, 2.4; 3.1 or 3.4 and exhausts air to the atmosphere through a fan outlet channel 44 and an exhaust air silencer 45.
  • the vacuum fan 40 comprises an atmospheric air intake 46 communicating with the inlet channel 43 and is selectively controlled by an air valve 47. Upstream of the air valve 47 is provided atmospheric air silencers 48 causing a pressure drop of approximately 25 kPa.
  • Fig. 6B is schematically illustrated a vacuum source 11 control arrangement.
  • the waste collection system 1 it is known to continuously monitor the vacuum pressure as well as the air flow in the waste pipes in order to immediately detect any blockage therein.
  • said known continuous detection of the vacuum level and the air flow is used in step S2 as an indication of whether or not blockage has been registered somewhere in the pipe system.
  • this is made by comparing the detected values with predetermined threshold values, based on which it is determined in step S3 whether a blockage has occurred.
  • the atmospheric air intake 46 is opened by opening the atmospheric air valve 47 in step S4. Thereby, a controlled amount of air is introduced.
  • the introduced air will have a controlled subatmospheric pressure.
  • the speed (RPM) of the fan 40 will be increased and, taken together these measures will secure optimum use of the vacuum fan 40 that has a poor energy efficiency in situations where the air intake is close to zero.
  • the controlled subatmospheric pressure will be obtained by producing the correct pressure drop across the silencers 48 being provided upstream of the air valve 47.
  • the speed of the fan 40 will be controlled based on the detected air speed during the emptying sequence, and such speed control may be performed by means of a variable displacement pump that is mounted on a power take-off of the vehicle 10 engine. As soon as the detected values return to normal the atmospheric air valve 47 is closed again, the speed of the fan is adjusted back to normal and the tank emptying sequence is finished in the normal mode in step S5.
