Ways to create a safe industrial working environment for the future

• Workers are more satisfied with their work
• Accidental drop to zero
• Building a good corporate image

Background

The construction industry has made a significant contribution to Hong Kong, shouldering the mission of building a better future, promoting the development of Hong Kong and providing a large number of employment opportunities.

 

 

 

 

However, work-related accidents are frequent in the construction industry, and there are many deaths from work-related injuries. Last year, there were nearly 3,000 industrial accidents involving the construction industry. Work accidents bring huge losses and heavy burdens. It will cause great pain for the injured workers and their families; for the company, it will cause huge financial losses and damage its image.

 

At present, the measures adopted by most contractors to prevent accidents mainly include:

• Provide safety training
• Use fall prevention facilities
• Carry out strict security audits

However, to reduce the chance of loss and casualties, the company must take more effective measures to prevent accidents, focus on on-site safety, and set up safety measures to avoid accidents.

The site safety device can effectively reduce the chance of accidents. Most accidents at construction sites are caused by human error, such as:

• The maintenance hole cover is not properly covered, causing the worker to fall accidentally
• Into the dangerous range of the excavator accidentally knocked down
• Water in the collection well is flooded, flooding the construction site.

Solution

As long as site safety devices are installed on the construction site, the chance of accidents will be greatly reduced. The site safety device is a combination of LoRaWan and sensor technology. The purpose is to reduce the possibility of accidents.

IoT technology LORAWAN – Thousands or even tens of thousands of node capacity connect easily

LoRaWan is a wireless communication technology designed to create low-power wide-area networks (LPWAN) required for machine-to-machine (M2M) and Internet of Things (IoT) applications. The information can be sent to any base station connected to the cloud platform at low cost, low power consumption, safety, and long-distance.

Management system optimization & Powerful back-end

There are four other functions in the back-end:

1. Multi-identity login interface: hierarchical access
2. Data visualization chart: Data will be displayed in various chart, such as column chart, bar chart, line chart, pie chart.
3. Instant data transmission: transfer messages in real-time via LoRaWan, Json, MQTT communication protocols
4. Complete data export

For construction site manholes

The magnetic control induction switch device can be installed on the manhole cover, and the magnetic control induction switch device can be arranged at the manhole head and the manhole cover position.

If the manhole cover is not properly covered:

• The device will immediately transmit the real-time location and real-time alarm to LoRaWan
• LoRaWan will send the alert to the cloud back-end

Managers can learn the real-time situation of the construction site through the management system or application, effectively preventing accidents.

For catchment wells

Devices can be placed in different locations outside the well to detect water level and flow.

If the water level reaches the upper or lower limit of water storage:

1. The real-time alarm system will immediately sound the alarm and then send out a full or lack of water alarm
2. Instant delivery to LoRaWan
3. LoRaWan will send the alert to the cloud backend

Managers can know the real-time situation of the construction site through the management system or application.

 

For mud digger

 

The contractor only needs to issue a luminous, sound, and vibrating smart worker card to each worker in advance and install a safety range signal transmitter and receiver device on the excavator.

If the worker exceeds the established safety range and is too close to the excavator:

1. The luminous, sound and vibrating smart worker card will sound to remind the workers to return to the safe range
2. The data will be transmitted to LoRaWan instantly
3. LoRaWan will transfer the data to the cloud backend
4. The management personnel can know the real-time situation of the construction site through the management system or application program. At the same time, the data can be used to train employees in the future.

For angle bracket

The contractor only needs to install a sensor device on the angle bracket, which can detect the data of tension and pressure and analyze the safety factor simultaneously.

 

If the pressure of the dog boom exceeds the normal range:

1. The device will immediately transmit the real-time location and real-time alarm to LoRaWan
2. LoRaWan will send the alert to the cloud backend
3. The management personnel can learn the real-time situation of the construction site through the management system or application program to take corresponding actions to prevent accidents effectively.

 

Conclusion

Installing site safety devices is the first step to create an ideal business environment for you.

Workers’ lives and the company’s image are priceless. It is the employer’s responsibility to protect workers’ safety. Site safety devices care for workers and at the same time defend all kinds of priceless treasures. Providing a safe working environment, reducing accidents to zero, and building a good corporate image is believed to be the goal of every employer. Furthermore, all government sectors are also actively encouraging contractors to focus on work safety and reduce the chance of accidents at work, thereby enhancing the organization’s good corporate image and minimizing any losses.
