The pressure with which the cleaning hose 3 acts and with the the cleaning liquid from the cleaning nozzle 6, which in the Canal structure 5 has been introduced, is acted upon by a pressure sensor 22 at the entrance to the hose drum 2, preferably after the last valve. Alternatively, the print for example also by a fix in the sewer cleaning car 1 built-in pressure sensor can be detected.

The pressure at which liquid emerges from the cleaning nozzle 6 and which is essential for working with the cleaning trolley 1 (a too little pressure leads to insufficient cleaning, too high pressure leads to damage to the sewer structure 5) detected by "calibration". The calibration nozzle is used for calibration 6 a pressure sensor attached and the pressure drop across the Hose 3 detected and as a fixed calibration factor in the computer entered in the black box 21. This also includes the one used Calibrated nozzle.

To calibrate, proceed as follows:

The principle is that each type of nozzle in combination with the used hose 3 (length and diameter of the same) calibrated must become. The calibration is preferably saved in the menu program.

Before starting work, the data of the sewer pipe to be cleaned 5 entered: tube diameter, tube shape (circular profile, egg profile or special shapes), pipe material. This is important because for each pipe material from the manufacturer the maximum permissible flushing pressures and specifications for the nozzle to be used as well as jet angle and Nozzle holes and amount of water are available.

With the method according to the invention, using a cleaning as an example of a canal structure, a protocol is created in which the essential data are given, and in the form of diagrams the pressure curve is shown when working with the sewer flushing car is. So time and place and the actual execution of the Work and the course of cleaning the channel 5 are precisely recorded and be proven. The "cleaning speed" will from the duration (time) of cleaning and the length of the least Route determined. The length of the cleaned route can, for example can be determined in the area of the hose reel 2 a displacement sensor acting on the cleaning hose 3 is provided, which, for example, via a roller on the hose 3, the each wound length recorded on the cleaning hose 3 and so outputs determined values to the computer.

An example of such a protocol is given below. 2 shows the pressure curve in the course of the according to the protocol performed channel flushing again.

example

The course of the pressure of the cleaning liquid on the flushing car 1, the determined by the pressure sensor 22 mounted on the flushing car 1 is, on the one hand, and the pressure with which the cleaning fluid emerges from the cleaning nozzle 6 in the sewer structure 5, on the other hand, results in the diagram shown in Fig. 2. This shows in the upper curves (higher pressures), the pressure at the flushing car 1 and in the lower curves (lower pressures), the pressure of the cleaning fluid at the nozzle 6.

In particular, the method according to the invention can be carried out using the described device, for example as follows, in detail described, carried out. In the case described below Example as a computer a portable computer with Microsoft Windows CE is connected to the computer.

testing procedure

• Bei einem bestehenden Auftrag werden die Stammdaten, die schon bei vorherigen Messungen eingegeben wurden, in der Eingabemaske vorgegeben. Der Benutzer paßt nur die Daten entsprechend an.
• Wurde ein neues Projekt begonnen, so muß der Benutzer die Stammdaten erst eingeben. Diese Stammdaten werden dann in das neue Projekt übernommen.

The user activates the PC of the Black Box 21. A link to "Hemar KRK" is visible on the display in the main menu (Fig. 3a). Tap the symbol twice in quick succession with the stylus. Then click once on the "New measurement" button to start a new measurement. The Project selection screen appears (Fig. 3b). Before master data is entered, the user decides whether to continue an existing order (project) or start a new order:

• In the case of an existing order, the master data that have already been entered in previous measurements are specified in the input mask. The user only adjusts the data accordingly.
• If a new project has been started, the user must first enter the master data. This master data is then transferred to the new project.

At the beginning of the master data entry (Fig. 3c) is automatically over the Black Box 21 read out the GPS time. This time is the beginning of the Working hours. There is the option in the Project selection menu (Fig. 3b) select an existing project or a new project to apply.

If you now tap the "Next» "button with the pen, the project master data are automatically entered into the Master data adopted.

The process can be stopped at any time by tapping the "Cancel" button quit and return to the main menu.

To scroll down the input mask (Fig. 3d), the Scrollbar on the right side of the screen is used by clicking on the arrows is typed to scroll. The scroll bar can also be pulled by yourself (briefly tap with the stylus and pull without stopping), to move the mask.

If the mask is moved all the way up, appear at the bottom again two buttons. By tapping "Next» "the Process continued and measurement started.

After entering the master data, the user starts the test process (using a button in the master data mask). The PC reads at this point the current GPS time from the computer. This Time is the beginning of the cleaning time.

The current measurement data are now shown on the PC display - as from the Computers are transferred - displayed. Furthermore, here in The measurement curve of the computer data is displayed in real time. Also the means the curves and the calibration data stored in the PC Data can be displayed during the test process.

The current measurement data are shown on the screen during the measurement shown (Fig. 3f), the measurement by tapping the button "Start" is started. If the measurement is running, the jumps "Start" button to "End". Doing so will appear on the screen (Fig. 3f) the measurement data are displayed as a curve, similar to that in Fig. 3 shown diagrams. By tapping the button "End" the measuring process is completed. The button jumps then continue on "Next» ", this is now tapped to the rest Enter master data.

When the cleaning process is complete, the user ends the Testing process on the PC using a button in the user interface.

The PC reads the current GPS time from the computer again. This Time is the end of the cleaning time. The test process is completed and an input mask for the remaining master data shown.

The user can now enter the remaining master data (Fig. 3e). When he has finished this process, the PC reads automatically via the Calculates the current GPS time. That time is the end of the Working hours.

Transfer to PC

To transfer the data to the PC, the PC is connected to the computer connected. In the example, the software 'ActiveSync' is on the computer installed by Microsoft. ActiveSync puts the data on the PC available as a drive on the computer.

This enables the software to load the data from this drive and to decompress further processing. The master data can be saved on the computer edited again.

The final measurement is saved on the computer and left on the PC, to the master data for further measurements related to this project belong to be able to take over.

The individual measurements on the PC are there for the various projects assigned. There is already a file on the computer with the corresponding one Project exists, then the measurements for that project saved. Otherwise the project data are read from the PC and a new project file has been created in which the measurements are taken become.

Once a project has been completed, the project data can be viewed using the Computer software can be deleted separately from the PC. It is also possible to transfer projects saved on the PC back to the PC to continue the work.

calibration

In the calibration, the calculated pressure at the nozzle as well the loss of friction of the hose is saved. The loss of friction the hose is specified by the manufacturer or in a separate one Measurement determined.

The calibration is carried out by two separate measurements be brought together. These measurements are initially in the usual form carried out at different pressure levels. Then the pressure data are measured at the flushing nozzle. For these two Measurements, the data is extracted in the form of a calibration table, which make the print data possible from the measured values to be calculated on the flushing nozzle.

Several of these tables for different hose lengths are in the calibration file. This calibration file will compressed and encrypted stored on the PC so that corresponding calculated data is displayed during the test process can be.

An example of calibration tables is given below: Hemar KRK calibration Jet : atomiser Diameter: 69 mm Nozzle bore: 2.5 mm Number of nozzles: 12 tube Friction loss: 0.05 bar / m Length: 150 m Pressure loss: 7.5 bar Pump pressure Nozzle pressure Pressure loss measured calculation.

Nozzle = pressure at nozzle + pressure loss hose

The calibration data are provided with a date which is from Calibration officer is entered. The calibration must all be carried out again for two years. So that this appointment in time can be perceived, the software in the H / PC alerts the Users three months before reach this appointment each time restart of the software. If the calibration date is exceeded measurement is no longer possible.

report

The test report consists of three parts and is by the calculator software printed. The first part contains the master data and an overview of the essential measurement data. The second part is a numerical representation of the measuring process (see the table on Page 4). The third part is the graphical representation of the measuring process (Fig. 2).

The measurement graphic contains three curves. The actual measurement curve from the measured pressure data (as supplied by the computer) consists. Another curve shows the pressure curve at the flushing nozzle This curve is made up of the measurement data and the calibration data calculated. The third curve represents the pressure curve of the vacuum pump (this data is also supplied by the computer).

The numerical representation contains the same data as the measurement graphic as a series of pressure values.

The master data essentially consists of the data of the user entered on the PC. There will be other, essential data prepared from the measuring process. All data that is determined automatically (such as date, times, etc.) are not from Enter user.

project report

The project report is a collective list of all the projects carried out Measurements of a project. In addition to the master data of the project the number and length of each posture as well as the total working hours listed.

In addition, the user can enter additional data can also be saved in the project file.

Computer software

The computer software is used to read in the measurements from Handheld computer 25 also manages the projects and enables Print test reports.

Data

The individual measurements are stored on the PC in compressed form so that the Make better use of storage space. When importing to the computer the data is decompressed and saved in the final variant.

The individual measurements are saved in separate files on the PC. There is also a project file that contains the master data of the project contains. This project file is compressed Variant saved on the PC to transfer the data to new ones Enable measurements.

The compressed files contain the same data as the final ones Files, just with an efficient compression algorithm packed.

The data of a project (the project master data as well as the individual measurements) are saved in a single file. It is therefore not possible for individual measurements to be "lost" go.

project data

In addition to the pressure history and the GPS data supplied by the computer and are saved in the measurement, there are still those Master data from the user partly on the PC and partly on the computer can be entered.

For example, the following master data can be saved become:
