1.Introduction: What do you know about the electrical plugs and sockets used in different countries? In pairs, describe some specific designs.

2.Vocabulary: Introduction (p. 23, source 4): an advantage/disadvantage of this format is….. another advantage/disadvantage is…., the problem with this system is…., this (shape/format/feature) stops…. from …ing, this (shape, format, feature) allows it to /helps it to/makes it easy to/make it difficult to….

3.Pre-reading vocabulary: Exercise 2, p. 22 (source 2). e lectrical plug, socket format, configuration, pin, rectangle, rectangular, triangle, triangular, cylinder, cylindrical, line, linear

4.Reading: Exercise 2, p. 22 (source 2). Read and translate the text.

1.There are circular pins for live and neutral. There is no earth pin. This is quite a common format in Europe and Russia. Its also quite widely used in India.

2. Here you have got circular slots for live and neutral. And the earth slot’s got a flat base with one side rounded over to form a semi-circle. This type only used in few places.

3. This one has rectangular blades for live, neutral and earth, in triangular configuration. This is the standard in the UK and Ireland, and a few other places. Malaysia and Singapore, for instance.

4. This plug has got circular pins for live and neutral, and has a cylindrical slot to receive the earth pin. It’s quite common in continental Europe, and in parts of Africa.

5. There are circular pins for live, neutral and earth, and the pins are arranged in linear configuration. This is a very commonly used format.

6. This is the standard in North America, and quite common in Central and South America. Used in Japan, as well. There are flat blades for live and neutral, and a round pin for earth, and there are laid out in triangular configuration. So an extremely widely used format.

5.Follow-up: Exercise 3, p. 22 (source 2). Match the descriptions (1-6) to pictures (a-f).

8.Communicative task (group-work or pair-work): In pairs think of some examples of manufacturing operations that often use the electrical plugs and sockets of different formats.

Monitoring and control

Цель: проведение в виде интерактивного занятия “Система управления зданием” the Building Management System (BMS) p.62-64 (source 2) http://en.wikipedia.org/wiki/Building_management_system изучение лексического материала по теме “Monitoring and control”;

Задание на занятие:

1. Introduction: In pairs, discuss the difference between an automated and a manual system. Suggest some operations that can be monitored and controlled automatically by the Building Management System (BMS) in a large building such as offices.

2.Vocabulary: Introduction p.62 (source 2): Sensor, detector, pick up, regulate, set off, trigger, measurement, control (adjust),sense, activate

3.Pre-reading vocabulary: Installation, security system, environment, humidity, operating fan, achieve, waste, a fire alarm system, electrical components, network

4.Reading: Read and translate the text. http://en.wikipedia.org/wiki/Building_management_system

A Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware.

Invented by Dr Peter Wright BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.

Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States. As well as controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.

An electric power system is a network of electrical components used to supply, transmit and use electric power. An example of an electric power system is the network that supplies a region's homes and industry with power - for sizable regions, this power system is known as the grid and can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centres to the load centres and the distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings and homes. The majority of these systems rely upon three-phase AC power - the standard for large-scale power transmission and distribution across the modern world.

5.Follow-up: Exercise 6, p. 64 (source 2). Match the words (1-10) to the definitions (a-j).

8. Communicative task (group-work or pair-work) Exercise 4, p 64 (source 2): In pairs, think of monitoring and control systems that are widely used around the home. Discuss how the following parameters are measured and/or controlled in these common domestic appliances.

Parameters: temperature, pressure, time, actions/movement

Appliances: boilers, heating systems, refrigerators, washing machines

The sensor or measuring systems

Pressure measurement is checking the force exerted by steam inside a vessel.

Temperature measurement is measuring the level of heat generated by an exothermic reaction.

Flow measurement is monitoring the speed of water travelling along a supply pipe.

Level measurement is monitoring the amount of cans moving along a conveyor belt.

Process recorders measurement is monitoring the amount of ethanol contained in a storage tank.
