  • January, 2019

    Very detailed presentation of the ZAC Pajol, in the 18th arrondissement of Paris, its history, its photovoltaic power station of 3500 m², its thermal power plant with 5 levels of heat recovery, and stormwater recovery to feed citizen garden reservoirs.

  • March, 2019

    Presentation of the first paths of development of activities around the photovoltaic power plant of the ZAC Pajol, with comparisons between the model and the real. And then we immerse ourselves in the presentation of the M-Rex, and finally open our menus to the new discipline of second, "Digital Sciences and Technology", known as SNT.

  • May, 2019

    The introduction of computer science as a discipline in its own right in the teaching of the school changes the lines. In this May issue, you will find its use in SNT, high school networks, and digital electronics (hardware). And a very big place for our work on M-Rex, thanks to the support of the FFR, Thales and the Université Paris-Descartes.

  • September, 2019

    Instrumented man, measured man, disruptive innovation, or continuity, multidisciplinary teams, ... as many terms that appear in the new programs, college, high school, and that are present with the M-Rex developed with engineers, technicians, and professors of university, of the FFR, of the University Paris-Descartes, and of Thalès TRAINING AND SIMULATION.

  • November, 2019

    How do I switch between my browser and a web page? How do I see all the packets running on my local network in real time? Give each student the means to memorize sustainably the essentials of a course, with simple techniques. Measure the electrical signals caused by the contraction of my biceps. All these points are discussed in this November newsletter.

  • January 2020

    The first activity around the ZAC Pajol that will be set up on Tpline, will have the objective of correctly situating the problem. Precisely locate the Halle, geographically, count the PV panels, and measure their inclination and azimuth, to finally know how much this PV power plant is likely to produce electricity. For the M-Rex, a first draft of the health part and the notion of muscular effort.

  • March 2020

    This special issue was originally intended to focus on Tpline, its operations and the various resources that could be found there and that are increasing from year to year. And then SARS-Cov-2 (the name of the virus) set in, and the rapid spread of Covid-19 (the name of the disease) led us to refocus this issue on reading the tests for this pandemic.

    • May, 2020

      This issue of deconfinement takes stock of the new activities of Tpline, put in place in March, April and May and shows you in the main lines, everything that is under construction and that should appear "soon!". The re-engineering of the activity on the control of the unloading speed of a pushbutton mechanism at Schneider is presented in detail.

      In the Halle Pajol - Paris 18e


      The pluri-technological project "ZAC Pajol" takes place in three dimensions and forms the basis of several pedagogical sequences:
      - A socio-cultural dimension which enables a work in the construction field to be placed and questioned. The main pedagogical approach is that of the investigation, which makes it possible to understand the various references and needs that led to the creation of this work. It fully addresses sustainable development and eco-design concerns.
      - A scientific and technical dimension that enables analysis, experimentation and simulation from numerical models of the work to understand their functioning and justify constructive solutions.
      - An engineering-design dimension to imagine, create, design and build an HEQ (high environmental quality) and VHEP (very high energy performance) for tomorrow’s buildings.

      The interconnection of networks with the internet
      

      In 2011, the "Lycée de l'Essouriau des Ulis" formed a partnership with Distrame around their intelligent energy management solution. The measuring sensors are connected to a server that integrates into the school’s Ethernet network, which itself is connected to the Internet.
      The objective of this practical work is to analyse the functioning of the network integrating this measuring system, find its private IP address, and the public IP address, identify the class of the network, etc.

      Energy balance of the Valmoutier pavilions
      

      All of Valmoutier pavilion has two pavilions equipped with temperature sensors, humidity and measuring the consumed electric power.
      The pavilion A (A1 until June 2015 and A2 since October 2015) is more energy, while the Pavilion B is rather less.
      The reasons are various:
      - Energy facilities or not (eg wood stove, CAP, ...),
      - Like radiators,
      - Family: two retirees or 4 people including 2 children,
      - Etc.

      Galileo High School in Cergy groups of three students prepare STIDD bachelor's degrees in the following options:
      - EE Electricity and Environment,
      - AC: Architecture and Construction,
      - SIN: Computer Systems and Digital
      .

      Is this refrigerator energy?
      

      We will study, by measuring the energy consumed each day, if a refrigerator is energy and it is possible to replace it with a return on investment.

      The refrigerator is housed in a housing south of the Isle of France (south of Paris).

      It consists of the refrigerator bought in 2008, and a system for measuring the power consumption CurrentCost. This material includes three current probes connected to a transmitter (433 MHz), which sends the values of the currents measured at a receiver (Envir housing CurrentCost).

      The latter is connected via a RS232 / USB adaptation cord to a computer itself connected to the internet. Thus, FTP transmission, the information is transmitted to TPLine server that can interpret and deduce the cost of electricity consumption.

      Schneider - Isméca manipulator
      

      This manipulator, located at the end of assembly line contacts of pushbuttons, has the function to enter contacts assembled on pallets placed on a moving belt, to drop them on another mat that takes them to the chain finish.

      This system consists of a mechanical part made around two cams for the actuation of a horizontal slide and a vertical slide. These cams are rotated, via a set pulleys / toothed belts, by an asynchronous motor reducer supplied by a frequency converter.

      The whole is controlled by a PLC.

      Our measurements are taken by accelerometers placed on the slides, a dynamic torque transducer mounted between the motor and the gearbox, a strain gauge mounted on the horizontal slide, an absolute encoder in reflected binary code placed after the gearbox and an oscilloscope Scopix measures the voltage and current input and output of the inverter.

      The various practical exercises proposed below on this system are available in their original version on the tpline.net site, accessible automatically from the buttons below, and on which you will have to identify yourself with your couple login / password Pass, provided by your establishment, or as a guest.

      Mistral vs TGV
      

      The system that we propose to study, shows the driver the speed to be respected to ensure traffic in complete safety of the TGV for the characteristics of the measured wind.

      It consists of a series of 12 Weather Stations (located near the LN5: Line Paris-Méditerranée) which are collections vane / anemometer, measuring one hand speed and wind direction, and performing of furthermore the real-time analysis of these measures such as short-term forecasting (a few minutes) the characteristics of the wind.

      These weather stations are maintained in perfect working condition by train specialized staff.
      Since these weather stations, information is processed and then transmitted to the TGV drivers approaching the critical point. The driver can adjust the speed of the train on the basis of the received signal in order to guarantee the perfect safety of passengers, despite the influence of wind (the Mistral) on the train.
