Technical scheme of tower crane remote monitoring system?

　　Brief introduction of tower crane remote monitoring system: 

　　The tower crane remote monitoring and management system is mainly to monitor and control all tower cranes on a construction site. Monitoring mainly refers to detecting whether each tower crane is sending its own position data; control mainly refers to adding and modifying the static data of the tower crane, sending and receiving the modification and sending of system parameters, and calibrating the radius of the lifting height. The system is a tower crane remote monitoring system, which only plays a role of safety protection for the tower crane. It is mainly used for remote real-time monitoring of the tower crane and remote transmission of tower crane working condition data to avoid safety accidents caused by operator negligence or misjudgment. Greatly guarantee the safe use of the tower crane.

　　The economy is developing rapidly, and a large number of safety accidents continue to occur, especially in engineering construction. Timely and effective supervision of the use process and behavior of cranes, tower cranes, etc. has become the most important thing to effectively control dangerous factors and hidden safety hazards, and prevent and reduce crane safety production accidents.

　　The remote monitoring of the tower crane is a high-tech intelligent product that comprehensively applies microelectronics technology, information sensing technology, and information communication technology. It is a digital electronic recording device for dynamic detection, which can be widely used in various types of cranes to achieve their working conditions. Real-time security protection monitoring.

　　The functions of the remote monitoring system for tower crane real-time status based on GPRS are as follows: 

　　1. Realize the GPRS transmission of data. This is the biggest highlight of the tower crane remote monitoring system compared with the domestic tower crane monitoring system. One of the existing domestic monitoring systems is to realize the monitoring of the stand-alone version, that is, to realize the monitoring of its working parameters on a single tower crane, but the monitoring parameters are limited and only limited to the monitoring of amplitude and torque; the other is based on this The above has been improved, and the group control of tower cranes in a small area has been realized, but it is incapable of monitoring multiple tower cranes across regions. With the seamless connection between GPRS network and INTERNET, we can transmit the collected parameter information to the remote monitoring software terminal on the INTERNET through the GPRS module at the work site of the tower crane, as long as the GPRS network covers all places. Under the monitorable range, the working parameters of the tower crane can be checked by logging into the Internet in the office.

　　2. Complete real-time monitoring of the working status of the tower crane, such as weight, torque, rotation angle, height, amplitude and wind speed. Among the factors that cause tower crane accidents, the lack of real-time status of the tower crane remote monitoring system or the lack of impact on the safety of tower crane parameter monitoring account for a large part of the accident. Therefore, the primary function of the tower crane remote monitoring system is to realize real-time monitoring of the six parameters of the tower crane when it is working, and to set the monitoring threshold of the tower crane monitoring system through the monitoring algorithm, so as to prevent or reduce the occurrence of tower crane accidents.

　　product composition：
　　Tower crane remote monitoring system includes: control host, weight sensor, amplitude sensor, height sensor, rotation sensor. The control host is composed of microprocessor, sensor and signal conditioning module, GPRS transmission module, relay module, keyboard and liquid crystal display module.

　　Product Features：
　　1) Data recording function：
　　During the operation of the tower crane, the remote monitoring system of the tower crane will collect the working parameters of the tower crane in real time with a sampling period of about 10 milliseconds. If the lifting capacity reaches more than 90% of the rated torque, the system will issue an early warning signal and save the data In FLASH, ? mainly includes torque rated weight, actual weight, hook height, hook amplitude, rotation, torque override, etc. The counting result is stored every 1.5 seconds. If an accident occurs, the data recorded by the system can be downloaded and recalled with a U-library disk, and inserted into the computer for querying the reason. The data can be stored for 10 years without loss after being sealed.

　　2) Safety protection function：
　　Tower crane remote monitoring system can realize the functions of various safety limiters of tower crane, such as lifting torque limit, lifting weight limit, lifting height limit, amplitude limit, rotation limit, etc. If the lifting weight reaches more than 90% of the rated torque, the system will send an early warning switch signal to control the crane to run in a safe direction and prohibit it from running in a dangerous direction; when it reaches 105%, the system will send an alarm switch signal to reduce the total The power is cut off to achieve the purpose of preventing accidents.

　　3) Real-time display function：
　　The key parameters of tower crane work, the tower crane remote monitoring system collects the working parameters of the tower crane in real time with a sampling period of about 10 milliseconds, and displays the moment rated weight, actual weight, hook height, hook amplitude, rotation, torque percentage, torque on the LCD screen in real time , Magnification, torque scale, etc. for the operator's reference to achieve safe and reasonable operation of the tower crane.

　　4) Realize GPRS transmission of data
　　Compared with the domestic tower crane monitoring system, the biggest highlight of the tower crane remote monitoring system is the seamless connection between the GPRS network and the Internet. The collected parameter information can be transmitted to the remote station through the GPRS module on the tower crane’s work site. The terminal is placed on the monitoring software terminal on the INTERNET, as long as the places covered by the GPRS network are under the monitorable range.
