Metro Upgrades to the Internet of Things for Smoother Phase IV Operations | Delhi News


New Delhi: The Delhi Metro Rail Corporation is known for introducing the nation’s capital, and indeed the rest of the country, to the world’s best practices in site management. For its ongoing Phase IV project, the company is using, for the first time, the “Internet of Things” (IOT) – a network of construction factories and machinery interconnected over the Internet via devices such as GPS, sensors , QR codes, data loggers, CCTV cameras and drones, etc.
When DMRC began work some two and a half decades ago, the sight of construction sites hidden behind barricades, truck tires carrying building materials washed to keep dust from blowing away, marshals guiding the traffic etc. was new to most Delhiites. The standards set by DMRC have become standard now. For the construction of its Phase-IV project, DMRC has decided to advance several stages.
A DMRC official said that apart from efficiency and timely completion of construction work, an important objective of adopting IOT in the Phase IV project was safety not only of DMRC workers and employees, but also motorists traveling near construction sites.
For example, all cranes used on Phase IV construction sites are equipped with “data loggers”, which are compact battery-powered devices with sensors, microprocessor and data storage. The data logger in the cranes used by DMRC also has SMS and Web alert function.
“It gives an alert in case of malfunction or tampering with its automatic charge indicator and also sends an SMS,” the official said, adding that the data was saved on its storage drive. Overloading beyond a crane’s capacity can lead to major accidents and alerting via data loggers helps prevent this.
The official said fixed CCTV cameras and Pan-Tilt-Zoom cameras, with at least a week’s backup, were used at all construction sites. “It helps in monitoring construction sites and also has a live view of all areas of construction sites,” he said.
“We are monitoring construction sites using drones as they provide access to site conditions throughout the corridor, especially where we cannot provide CCTV cameras such as above ground plans. water, rivers, launching beams, gantries, etc.,” he said.
For the first time, DMRC uses QR codes on all its facilities and machinery, except for lifting tools and hoists, electrical distribution boxes, etc. the competence of the operators, etc. It also contributes to the paperless work initiative,” he said.
DMRC was also carrying out GPS monitoring of all factories and construction machinery, the official said. “Live monitoring of construction equipment and machinery gives clear information about its speed, stops, approved route, etc.,” he said.
The company has installed cruise control in all construction-related vehicles so they don’t exceed a pre-set, preset threshold, he said. “In addition, all vehicles are fitted with rear-view cameras to give clear visibility through a display screen in the operator’s cabin when reversing,” he said.
“There is also provision of side and rear protection devices (RUPD and LUPD) in construction vehicles,” he said. These devices prevent accidental entanglement of a vehicle from the rear and side if the other vehicle loses control of its motion and prevent serious injury to the occupants of these vehicles.
Apart from these, DMRC continues to use “three-layer protection” on road diversions, which include traffic cones, PVC crash barriers and then concrete barriers. “We create dedicated paths for road users, use retro-reflective tape, ‘work in progress’ signage, illumination of barricade signs through a rope light and light bracket or pole, etc.”, did he declare.
