What safety protection measures are there for compact cabinets in Zhengzhou?

1. A pair of infrared sensors are installed in the middle of the entrances on both sides of the rack, and reflective panels are installed on the opposite racks, forming an active human-sensing protective barrier. This active infrared sensor has two protective functions. First, if someone suddenly breaks into the rack while it is in operation, the infrared sensors immediately detect it and automatically stop the system. Second, when the compact shelving is opened, the infrared sensors automatically count and register the number of people entering the row area. If all those who have entered have not yet exited, the system will indicate that someone is present and prohibit any form of rack movement. This ensures safe and effective protection for people.

2. This active infrared also realizes automatic control of the lighting in the column area. When the number of people entering is not 0, the system will automatically turn on the lighting in the column area. When the number of people entering is 0, the system will automatically turn off the lighting in the column area.

2. Automatic counting and display of the number of people entering the warning protection function

1. After the Zhengzhou compact cabinet moves into place and detects someone entering the column area, it will automatically enter the prohibited movement protection state. At the same time, the digital display tube of the rack will show the number of people entering and trigger the lighting to turn on. If you need to continue moving, you must lightly press the "Stop" button on the panel.

The lock operation can be released by clicking the "Stop/Clear" button. When the compact shelving is in the prohibited movement state, all operation commands on the shelf are invalid.

2. Automatic shutdown function when no one operates the system for a certain period of time (this function can be turned on or off by the group switchboard):

1) If this function is turned on, when the staff forgets to close the shelves, a voice alarm will sound within a certain period of time, the lights will be automatically turned off, the shelves will be automatically closed, and the compact shelving will be locked.

2) Through computer program management software, when the staff forgets to close the shelves, a voice alarm will sound within a certain period of time, the lights will be automatically turned off, the shelves will be automatically closed, and the compact shelving will be locked.

3. Function of Zhengzhou compact cabinet strip pressure sensor:

1. A strip pressure sensor must be installed at the bottom of the frame. When a person or object touches the strip pressure sensor, the frame will automatically stop and lock.

2. The strip pressure sensor will function when the pressure is ≥ 200g at any location.

3. The electric compact shelving system will stop immediately in the following situations:

1) Trigger the safety system;

2) Press any of the following operation buttons on the handset during exercise:

3) Foreign objects enter the moving channel;

4) Books fall during movement and bookshelves touch objects on the floor of the aisle;

5) Any safety device fails;

6) Experiencing reverse resistance during operation;

4. When any abnormal situation occurs, the fault light will turn on or an alarm will sound.

5. When the safety system is triggered, any moving bookshelf will come to a complete stop within a sliding distance of ≤60mm.

4. Use 24V low voltage DC system power supply

1. The entire control system uses 24V low-voltage DC power. Each cluster has a power supply box that directly converts 220V mains power into 24V DC output. The 220V input is equipped with a fuse and a dedicated leakage circuit breaker to ensure safe operation.

2. Due to the use of 24V DC voltage, the wiring inside the entire metal frame is very safe, eliminating the risk of electric shock to the human body due to leakage of certain high-voltage wires.

5. Automatic power-off function of Zhengzhou compact cabinet

1. A dedicated fuse is also installed in the 24V output circuit. When a short circuit or overcurrent occurs, the fuse will immediately blow and the circuit will be cut off, ensuring safe power use for the entire system.

2. When the motor is overloaded, the bookshelf stops immediately.

6. Fireproof and heat insulation function

1. All motors are powered on and the set time is 25 seconds, which eliminates the safety hazards caused by motor heating and ensures that the motor temperature does not exceed the warehouse temperature by 5℃.

2. All column drive motors are placed in a chassis lined with fireproof and flame-retardant materials.

3. The contact area between the chassis and the motor is equipped with two layers of hollow steel plates, which are sprayed with flame-retardant powder. This allows the heat energy from the motor to be conducted in a targeted manner, preventing the heat from being transferred to the shelf.

7. Zhengzhou compact cabinet monitoring function

Each rack has an independent safety circuit system to monitor the normal operation of the safety system. If any safety protection component is abnormal, the system will automatically lock and prompt, and then wait for maintenance.
