Railway skylight operation is an important guarantee for the safe operation of trains. High speed railways generally set up comprehensive maintenance skylights for 5-6 hours at night to perform comprehensive maintenance on the lines, communication signals, and power supply equipment. Maintenance personnel need to enter the railway through the maintenance channel for equipment maintenance.

Most railway maintenance channels are set outdoors, and due to the difficulty of outdoor wiring, traditional padlocks are mostly used for the fence doors of maintenance channels. With the advancement of technology, traditional padlocks are gradually being replaced by smart locks such as password locks and electronic locks. However, during maintenance, it is inevitable that there may be delays in work progress due to unlocking. For example, poor outdoor weather can cause locks to become waterlogged, frozen, rusty, and unable to open, multiple locks on a door require multiple departments to be present to unlock, keys lost and unable to open locks, etc.

In response to these situations, we recommend a 4G dual channel intelligent padlock with a good perspective.

The Good View 4G dual channel smart padlock has three unlocking methods: remote, Bluetooth, and smart key unlocking. The smart key unlocking has two unlocking channels: contact channel and non-contact channel, which are independent of each other. Maintenance personnel can choose the unlocking method based on the actual situation of the day, and all unlocking methods have the function of uploading opening and closing lock records, which can be viewed on the APP, WeChat mini program or platform. Locks have anti disassembly, anti pry, high temperature, water immersion, and vibration alarms. The lock is equipped with a wide temperature battery that can supply power normally at -40 ℃ -+80 ℃. There are 9600mAh rechargeable batteries and 16000mAh disposable batteries to choose from. The lock body is made of 316L stainless steel material, and the outer shell is made of PA66 imported material. All internal components are waterproof treated to ensure that the lock will not rust or malfunction due to weather conditions or water ingress. A fence door only requires one padlock, and maintenance personnel can unlock it remotely or with an authorized key. The 4G dual channel intelligent padlock can achieve multi person authorization and management, no longer worrying about too many locks on the door and the need for personnel to arrive before entering. The padlock also has GPS+Beidou+base station positioning. After authorization with a smart key, all 4G dual channel smart padlocks within the responsible road section can be opened. The locks have inspection functions, reducing the difficulty of key management and strengthening lock information management.
