The Valve and Actuators Manufacturing Cluster of South Africa, VAMCOSA – was established in 2011 under the auspice’s of the South African Capital Equipment Export Council (SACEEC) in an effort to stem imports and re-establish the South African valve manufacturing industry, through the dti’s industrial development framework.

The Procurement of locally manufactured products is one of the levers identified by government to support Industrial Development in South Africa. The amended regulations to the Preferential Procurement Policy Framework Act (PPPFA) in 2011 empowers the dti to designate industries, sectors and sub-sectors for local production at a specified level of local content. National treasury issued the instruction note to all procuring public entities in 2014 – affectively making the local content minimum threshold for the procurement of valves and actuators at 70%. This is applicable to all public entities including state owned entities, government departments, municipalities, and water boards – even if the entity is procuring through a contractor or consultant.

VAMCOSA as a cluster represents 90% of the local manufacturing market for valves and actuators and through its efforts continues to promote the capability and capacity of the South African industry to service not only the needs of South African customers but also a global market.

VAMCOSA is committed to seeing the sustainability and growth of the industry through the value chain from the foundry sector through to transport and – this is key to unlocking the multiplier effects around supporting the impact of manufacturing in South Africa. Emphasis is placed on key programmes such stakeholder engagement with key customers, to understand and develop the industry according to their requirements as well as skills development, finding and attracting critical skills for the sector at a high school level as well as empowering the industries next generation.

Local Content means local manufacturing and adding value within the South African economy, creating and sustaining jobs in South Africa, putting our economy back on the road to recovery.

A people counter is a device used to measure the number and direction of people traversing a certain passage or entrance per unit time. The resolution of the measurement is entirely dependent on the sophistication of the technology employed. The device is often used at the entrance of a building so that the total number of visitors can be recorded. Many different technologies are used in people counter devices, such as infrared beams, computer vision, thermal imaging and pressure-sensitive mats

Infrared beams
The simplest form of counter is a single, horizontal infrared beam across an entrance which is typically linked to a small LCD display unit at the side of the doorway or can also be linked to a PC or send data via wireless links and GPRS. Such a beam counts a ‘tick’ when the beam is broken, therefore it is normal to divide the ‘ticks’ by two to get visitor numbers. Dual beam units are also available from some suppliers and can provide low cost directional flow ‘in’ and ‘out’ data. Accuracy depends highly on the width of the entrance monitored and the volume of traffic.
Horizontal Beam Counters usually require a receiver or a reflector mounted opposite the unit with a typical range up to 6 metres (20 ft), although range finding beam counters which do not require a reflector or receiver usually have a shorter range of around 2.5 metres (8 ft 2 in).
Vertical beams are somewhat more accurate than horizontal, with accuracies of over 90% possible if the beams are very carefully placed. Typically they do not give ‘in and out’ information, although some directional beams do exist.

Computer vision
Computer vision systems typically use either a closed-circuit television camera or IP camera to feed a signal into a computer or embedded device. Some computer vision systems have been embedded directly into standard IP network cameras. This allows for distributed, cost efficient and highly scalable systems where all image processing is done on the camera using the standard built in CPU. This also dramatically reduces band width requirements as only the counting data has to be sent over the Ethernet.
Accuracy varies between systems and installations as background information needs to be digitally removed from the scene in order to recognize, track and count people. This means that CCTV based counters can be vulnerable to light level changes and shadows, which can lead to inaccurate counting. Lately, robust and adaptive algorithms has been developed that can compensate for this behavior and excellent counting accuracy can today be obtained for both outdoor and indoor counting using computer vision

Main concept behind this project is to measure and display the number of persons entering in any room like seminar hall, conference room. LCD or seven segment display display placed outside the room displays this value. And when number of persons inside the room are zero, power supply inside the room can be cut using a relay interface. Second part of project serves the functionality of a door-latch opening using a password entered through keypad. As well as sending this data to a computer through serial port. This module also turn on buzzer if 3 wrong passwords are entered consequently. User can change this password anytime he/she wish using a keypad.
