How to ensure the safe operation of hospital elevators through traction motor power self-detection and door system? ​

Intelligent guard: traction motor power self-detection intelligent control system ​
During the frequent use of hospital elevators, the braking force of the traction motor will change with the increase of time and the number of times used, and potential fault hazards will arise quietly. The traction motor power self-detection intelligent control system equipped with MRL hospital elevator always protects the safe operation of the elevator. ​
The system has a powerful self-diagnosis function, which can regularly and timely detect the braking force of the traction motor. Unlike the traditional manual detection method, this intelligent self-detection does not require too much human intervention, and can autonomously and accurately determine whether the braking force of the traction motor is within the normal range. When a slight change in the braking force is detected, even an extremely small abnormal fluctuation, the system will immediately activate the early warning mechanism. Through the built-in algorithm and data analysis model, the system will conduct an in-depth analysis of the abnormal situation to determine whether this change will develop into a potential fault or safety problem. ​
Take the situation where the elevator runs continuously for a long time, causing the traction motor to overheat, which may affect the braking force. The self-detection intelligent control system can keenly capture the subtle effects of temperature changes on the braking force at the beginning of the motor temperature rise. By real-time monitoring of various operating parameters of the motor, such as current, voltage, speed, etc., and combining the preset safety standards and historical data for comparative analysis, the system can quickly determine the changing trend of the braking force. Once it is found that the braking force is at risk of falling below the safety threshold, the system will immediately take corresponding measures, such as automatically adjusting the elevator's operating mode, reducing the elevator's operating speed, and reducing the motor's load, thereby avoiding serious safety accidents such as elevator slippage caused by insufficient braking force. ​
In addition, the system also has learning and adaptive capabilities. As the elevator's operating time increases and the use environment changes, the system can continuously accumulate data and optimize the detection algorithm and judgment criteria. It can automatically adjust the frequency and accuracy of braking force detection according to factors such as different floor heights, load conditions, and operating time periods, ensuring that potential safety hazards can be discovered in a timely manner in various complex situations, providing all-round and dynamic protection for the safe operation of the elevator. ​
Safety barrier: door system and door opening restriction device​
The elevator door is the only way for passengers to enter and exit the elevator, and its safety is directly related to the personal safety of passengers. The door system of MRL hospital elevator also adopts a series of advanced technologies to build a solid safety barrier for passengers. ​
The design of the door system fully considers the particularity of the hospital environment. In hospitals, it is common for patients with limited mobility to enter and exit the elevator in wheelchairs or stretchers, which requires the elevator door to have sufficient width and stability. While ensuring the strength of the door body, the door system of MRL hospital elevator optimizes the structural design of the door and increases the door opening width, which facilitates the smooth passage of patients and medical staff. At the same time, the door body is made of high-strength and lightweight materials, which not only ensures the durability of the door, but also reduces the energy consumption of the door. ​
In order to prevent the elevator door from pinching passengers during the closing process, the door system is equipped with high-precision sensors. These sensors can sensitively detect the slight contact between the door and the object. Once an obstacle is detected, the door will immediately stop closing and automatically reopen. This anti-pinch function not only improves the safety of elevator use, but also reflects the humane care for passengers. ​
The door opening restriction device is another major safety highlight of the door system. When the elevator is not completely stopped or is in an abnormal operating state, the door opening restriction device will play a role to prevent the elevator door from opening. This device works closely with the elevator control system to monitor the elevator's operating status and location information in real time. When the elevator fails, such as abnormal operating speed, loss of floor signal, etc., the door opening restriction device will respond quickly and lock the elevator door to prevent passengers from walking out of the elevator in dangerous situations and avoid serious accidents such as falling. ​
In actual applications, when the elevator encounters a sudden power outage and stops running, the door opening restriction device will determine whether the elevator is at the floor leveling position based on the elevator's real-time location information. If the elevator is not at the leveling position, the door opening restriction device will keep the door locked to ensure the safety of passengers in the elevator and wait for the arrival of professional rescue personnel. Only when the elevator is safely rescued to the leveling position will the door opening restriction device be unlocked to allow the elevator door to open normally. ​
MRL hospital elevators fully guarantee the safe operation of the elevator through the coordinated work of the traction motor power self-detection intelligent control system, the door system and the door opening restriction device. The traction motor power self-detection intelligent control system prevents risks from the core power source of the elevator, and the door system and the door opening restriction device provide safety protection at the key link of passengers entering and exiting the elevator. The application of these technologies not only reflects the high attention paid to the safe operation of hospital elevators, but also creates a safe and reliable vertical transportation environment for patients, medical staff and all people who use elevators, making hospital elevators a truly safe passage to protect lives.
