Does the maintenance of turnstiles affect the operation of shopping malls?

一, Common sorts of problems and their causes in rotating turnstiles
1. Failure of the mechanical structure
Wear on the bearing: The 304 stainless steel shaft and bearings are the most important parts of the rotary brake. They can handle thousands of daily opening and shutting impacts for a long time, but they can wear out if they aren't lubricated enough or if dust gets in. For instance, the turnstile at a certain mall made strange noises because the bearings were stuck. It takes two hours to take apart the machine core and replace the bearings during maintenance.

Loose transmission parts: If screws or other connecting parts are loose, the brake lever may not be in the right place, or the stop lever may shake. A passenger collision happened at a subway station because the lever screw came free, which caused the gate rod to stop 15 centimeters off course.
In place magnet displacement: If the Hall element and the reducer cam position are not aligned correctly, the brake may not be able to tell what state the switch is in. A certain retail mall's gate had a safety hole because the magnet was out of place, which let people through without the gate rod going back to its place.
2. The electronic control system isn't working right.
Problem with the power supply: The gate can shut down if the power sockets are broken, the voltage is unsteady, or the wiring is old. The gate controller at a certain mall burned out because the voltage kept changing. This made the entrance route unusable for an hour and a half.
Sensor failure: If the light-sensing sensor is blocked or broken, the gate may not be able to tell if someone is passing through. For instance, a certain gate opened automatically when no one was passing by because dust had built up on the sensors. This led to the theft of commodities.
Communication failure: If the gate and the top computer can't talk to each other, data may be lost or remote control may not work. Because to bad communication, the gate at a certain mall lost 30% of the daily passenger flow statistics data.
3. Problems with software and algorithms
Error in parameter configuration: If the speed, sensitivity, and other settings on the gate are not adjusted correctly, traffic may not flow as well. The gate of a certain shopping mall was slowed down, which meant that people had to wait in line for up to 10 minutes at the entry during busy times.
Algorithm vulnerability: The facial recognition gate might not work right or might not let someone in because of problems with the algorithm. In bright light, the facial recognition rate at a certain shopping mall entrance has plummeted to 60%, which means that customers have to swipe their cards over and over again.
二,The immediate effect of maintenance work on how the mall works
1. Blocked channels and crowded passenger flow
Keeping up with a single channel: Fixing just one gate channel in a mall with one entry can cut the number of people who can enter by half. For instance, when a shopping mall was fixing one of its gates, the number of people waiting to go in went up to 50, and the wait time went up to 8 minutes.
Full channel shutdown: When all gates need to be closed at the same time for emergency repair, the entrance is fully blocked. Because the gate control system wasn't working right, a certain mall had to check tickets by hand, which caused a 2-hour backup at the entry.
2. Increasing the danger of security
Unprotected passage: If maintenance doesn't put up temporary barriers to keep people out, anyone can get in. While the gate at a certain mall was being fixed, the passageway was not closed, thus three kids were able to get into the entertainment area without checking their tickets.
Data interruption: Passenger flow statistics may be affected by maintenance, which could have an impact on the safety warning system. For instance, a theft happened while a certain shopping mall gate was being repaired, and security couldn't respond quickly since they didn't have real-time data on how many people were coming and going.
3. Merchants lose money
Customers leave: Customers may go to rival malls if there is a lot of traffic at the entrance. Research shows that a broken gate at a certain mall caused foot traffic to drop by 12% and revenues for nearby businesses to drop by 8%.
Logistics blockage: The freight channel is closed for maintenance, which could slow down the merchant's ability to restock. During the upkeep of a gate in a certain shopping mall, the fresh food vendor couldn't restock the items quickly enough, which led to a daily loss rate of 5%.
三,Optimization strategy for reducing the effects of maintenance
1. Building a system for preventive maintenance
Modular design: Using a modular construction that can be easily replaced, which cuts the average time to repair (MTTR) to less than 30 minutes. For instance, one shopping center gate has a DC brushless motor and a separate control board. During maintenance, just the broken module needs to be replaced.
Intelligent self-checking system: Sensors included into the system keep an eye on things like motor temperature, bearing vibration, and other factors in real time, letting you know about possible problems before they happen. A self-checking mechanism at the entrance to a certain mall has cut the number of times it breaks down suddenly to 0.3 times a month.
Plan for periodic maintenance: Set up a three-level maintenance system that includes daily, weekly, and monthly inspections. Focus on checking parts that are likely to break, like cleaning sensors and lubricating bearings. After doing preventive maintenance on a certain shopping mall's gate, it now lasts for 8 years.
2. Improving the workflow for emergency maintenance
Managing the inventory of spare parts: Set aside a safety supply of spare parts that are utilized often, like bearings, motors, and control boards, to make sure that replacements can be made within four hours. A spare parts management system has cut the time it takes for maintenance to respond at a given mall to 1.5 hours.
Parallel operation mode: When fixing the primary channel, turn on the backup channel and send more security guards to redirect passenger traffic. One retail center uses a "1 main+1 backup" channel setup, and the traffic flow only slows down by 20% during maintenance.
Support for remote diagnostics: IoT technology makes it possible to change parameters and find faults from a distance, which cuts down on the time needed for on-site maintenance. A certain mall gate supplier fixed 30% of the problems online by diagnosing them from a distance.
3. New ways to work together on operations
Managing the maintenance window: Schedule maintenance work for times when there aren't many passengers (like 2–4 am) and let them know ahead of time. A certain shopping mall was able to cut the effect of maintenance on operations down to 0.5 hours per time by doing it during off-peak hours.
How merchants are paid: Give merchants whose businesses are hurt by repairs a break on their rent or money for advertising. A certain retail complex gave merchants a 50% discount on their daily fee while the gates were being repaired.
Improving the customer experience: Create temporary ticketing areas in the repair area and make it easy for people to pay using their phones or by scanning their faces. During the time the gate was being fixed, a specific mall kept customers waiting for no more than three minutes by putting temporary gates and improving the flow line.
