Background
The construction industry is a high-risk area for safety accidents. Tower cranes are widely used in construction due to their high-efficiency vertical transportation capabilities.
However, improper operation of tower cranes can lead to numerous high-risk situations. Traditional management methods rely on the driver's self-discipline and visual supervision by safety officers, resulting in many blind spots.
Construction companies urgently need a technological means to remotely monitor the operating status of tower cranes in real time, effectively warn of dangerous operations, and reduce accident risks.
Client Requirements
- Collecte de données
Real-time acquisition of various sensor data from the tower crane is required, including output data from tower lifting sensors, width sensors, height sensors, angle sensors, etc.
- Early Warning
Equipped with real-time automatic warning capabilities, the system triggers both audible and visual alarms when approaching or exceeding rated limits, prompting immediate corrective action.
- Operations/management
All operational logs and alarm information are recorded, creating an unalterable "black box" for tracking incidents and ensuring complete traceability for safety and maintenance.
- Visual Analysis
The platform offers a monitoring view of the entire tower crane fleet, displaying real-time statuses and locations, along with historical data access, alarm statistics, and operator behavior analysis for enhanced decision-making.
Technical Solution
The system consists of three parts: tower crane monitoring devices, a wireless transmission module, and a monitoring and management center.
IOTRouter provides the ET3410 remote I/O data acquisition and control module as an intelligent terminal for the tower crane remote management solution, connecting to various sensors and uploading data to the wireless remote management platform via a 4G network.
ET3410 core features include
1. Multi-channel acquisition capability: 4*DI, 4*DO, 1*RS485
2. Seamless expansion: Its unique head-to-tail cascading design enables seamless and easy expansion of I/O interfaces.
3. Easy integration: Supports Modbus RTU/TCP and JSON protocols, eliminating complex configuration. It automatically adapts register addresses for plug-and-play functionality, simplifying the device integration process.
4. Stable Transmission: It can accommodate flexible combinations of digital and analog interfaces, easily achieving 12, 16, or 20-channel configurations while ensuring smooth network transmission.
Main System Functions
1. Acquisition des données : The host unit acquires real-time sensor signals such as amplitude, height, angle, weight, and wind speed.
2. Traitement des données : Calculates the torque value under current operating conditions in real time and compares it with preset lifting characteristic curves, executing local alarm and control logic.
3. Transmission des données : Processed key data, alarm information, and operation records are uploaded to the cloud platform in real-time via a 4G network.
4. Data Analysis: The platform stores and visualizes various types of data, providing different views and reports for different roles.
5. Multi-Level Alarms: 1. Early Warning (reaching 90% of rated value); 2. Alarm (reaching 100% of rated value, audible and visual alarm)
6. Remote Operation and Maintenance Function: Administrators can remotely view equipment status and, in special circumstances (such as severe weather), remotely issue commands to control the guide rails and grab buckets.
Advantages and Value
- Improved Site Safety
- Digital Compliance Records
