Vision, the new real-time monitoring application

JEAN LUTZ S.A. releases its monitoring application for Android.
For customers who have JEAN LUTZ S.A. devices that communicate (such as the DIALOG), the Vision application allows them to supervise the progress of the work in real time, on their smartphone and tablet. In particular, it offers the possibility to check the parameters and the quality of the work in progress thanks to the operator's screen view.
It is a mobile solution that meets the current need to access complete and relevant data for jobsite monitoring.

Developed on the basis of Vision web, the Android application enhances its offer with new features.

It is now possible to view:

  • the screens of the devices in real time,
  • the information of the jobsite,
  • the real time position of the machines on a map,
  • the recorded parameters,
  • statistics (depth, volume, overconsumption and records),
  • the generated reports,
  • messaging.

NORMA2, measure of highly accurate Geographic North (True North)

The NORMA2, coupled with the Dialog, accurately measures the orientation and inclination of the mast on which it is mounted.
Robust sensor developed to withstand shock and deformations, it is composed of two precision GPS receivers and a central unit protected by a robust stainless steel structure.

It is an efficient aid for Kelly piles, auger cast piles and mine or quarry parameters. It enables an accurate inclination and drilling direction control, independently of the positioning of the machine.

The NORMA2 relies entirely on GPS for orientation determination, so it is insensitive to magnetic interference and nearby metal objects.
No effort or additional calculation is required, the driller controls the positioning of the mast on the screen of the DIALOG.

Sensors for measuring the deviation of piles

Experts in auger or Kelly piles are aware of this: the verticality of the structures may need to be carefully controlled when making secant piles and certain types of isolated piles. For this, Jean Lutz has designed two new measurement systems: Prad and Taupe sensors.

The Prad sensor fits both the auger and Kelly at the bottom of the tool. It measures the deviation and the bottom pressure: at each ascent of the drilling, the Prad transmits the data by radio to a computer and display interface installed in the machine's cabin - typically the Dialog interface.
Jean Lutz SA devices are able to manage data transfer to the supervisory offices of the company, and  to receive instructions or operating procedures, and produce configurable reports.

In the case of Kelly piles, the Prad provides measurements are transmitted after each ascent, close to real time each time the bucket comes out of the excavation.
For continuous auger piles, data transfer occurs only once the pile is complete, after drilling and concreting. The operator then has all the information that will allow him to better reposition the next pile, to consider the possible deviation of just finished pile. It can also adjust the amount of concrete to be injected.

The Taupe measurement system, specific to augers, measures and transmits in real time all the information of deviation and pressure of concrete: adjustments during drilling and concreting are possible.
The transmission of data between the bottom and the head of the auger is ensured during the construction of the pile by a single-stranded conductor, which will be put in place along the auger.

Prad and Taupe sensors use advanced technologies based on accelerometers and gyroscopes.

Measurement, control and recording of injection parameters with CINTAC

CINTAC 15 is a device for measuring, controlling and recording injection parameters.
Equipped with a large touch screen with a graphical intuitive interface, its use extends from the measurement and the recording of the parameters (pressure, flow, volume) to the control of the pumps (regulation of the pressure and the flow), as well as controlling and following complex instructions.

CINTAC can control and manage up to 12 pumps.

Parameters :

  • Smoothed / instantaneous pressure
  • Flow / Volume
  • Recording according to time / events
  • Description of the sections (numbering, ribs, ...)
  • Events described by the operator
  • External events captured (uprising, ...)
  • Up to 12 pumps

Piloting :

  • Simple manual / pilot mode switching
  • On / off regulation
  • Proportional pressure / flow rate regulation in automatic mode

    (The pump must be equipped with proportional valves)

Controls :

  • Fixed / variable safety pressure
  • Absolute instructions or per unit of depth
  • Stop on thresholds (set volume, set pressure and holding time, GIN, minimum flow)
  • Automatic hold or refusal / reminders
  • Servo-controlled pressure / flow rate: (fixed, variable in time GIN, cut into time phases)

Thanks to the Vision system data is accessible from any device connected to the internet, the measurements can be monitored at any time on a remote screen.
This also makes it possible to obtain graphical representations of the measurements and data for the purpose of quality control.

The NEMO BT, a sensor for diaphragm walls

The NEMO BT is a deviation and inclination sensor for grabs.
It is equipped with a Bluetooth radio transmitter and a battery. In the absence of communication (immersed sensor), the measured values ​​are stored in the internal memory of the NEMO BT, they are transmitted from the sensor to the device.

The DIALOG MX measures the trajectory made by the grab as it descends into the wall. The differences between the vertical axis of the wall and the path followed by the bucket measure the deviation.

The three main axes of deviations are measured:

  • in the vertical plane, parallel to the axis of the wall
  • in the vertical plane, perpendicular to the axis of the wall
  • the deviation due to the rotation of the bucket around its own axis

The trajectory of the grab is calculated by integrating the inclinations as a function of depth and rotation as a function of time. The algorithms of the DIALOG MX correct the systematic errors generated by the sensors.

The DIALOG MX TRB set includes 2 sensors: a depth sensor and the NEMO BT sensor installed on the grab.
The NEMO BT sensor measures the inclination of the grab (inclinometers) and its rotation (gyroscope). During the descent of the grab into the wall, the NEMO BT sensor stores its internal measurements in memory. When the grab returns to the surface, the NEMO BT sensor transmits its measurements to the DIALOG MX which displays the trajectory followed by the grab (horizontal & vertical deviation and top view for rotation). The measurements are simultaneously saved in memory by the DIALOG MX.

Thanks to the Vision system data is accessible from any device connected to the internet, the measurements can be monitored at any time on a remote screen.
This also makes it possible to obtain graphical representations of the measurements and data for the purpose of quality control.
