Shanghai application of networking technology into the elevator management
Source：Updated：2015-05-28 08:35:28
In the wisdom of urban construction, Shanghai recently applied Internet of things to lift the elevator become smart ". Tens of thousands of elevator into the net, once fault occurs, it uploads the central control center, locking the focus where, but also through the sensor, remote automatic physical, warning sub healthy state.
175000 in the whole city with the elevator, Shanghai has become the largest city in the world to lift the elevator. However, the life of the elevator actually than building much shorter, about one tenth has over 15 years of service life, and some even "sick" operation. As a special equipment, each elevator is the statutory monthly maintenance 2 times, while many elevators often do not bad or maintenance ".Which the elevator is what the map intuitive
Changning District, Jing'an District, Shanghai City, Changhua Road, new enabled user service center in Shanghai Mitsubishi large screen wall, from Chinese map zoom into a map of Shanghai to as a pilot zone and free trade area of the test, the "wisdom" of the elevator distribution all visualization. They bear the responsibility of national enterprise technology center, R & D of this elevator networking, the current network of elevator up to 40000 units. On this basis, the center also with the Municipal Quality Supervision Bureau, the 110 linkage, as the elevator emergency management center in Shanghai city to assume the whole city emergency command work.
So far, the largest domestic elevator manufacturing sales enterprises, has more than 500000 elevators to the market. And the elevator retains the quantity is more than 300 million units, the eighties and nineties of the last century the installation of the elevator most still in use, enter "aging" and "super aging" period, serious wear of parts, repair and maintenance costs, neither safe, and the cost of manpower. When a lift works, hundreds of parts cooperate with the work, "the wisdom lift" can monitor dozens of state parameters. Once a lift something, big screen in the center of the map that shows, for the first time to complete the remote fault diagnosis and maintenance personnel to make rapid response to "suit the remedy to the case". For the newly installed elevator, networking module can be embedded; for in the elevator, can be convenient to install.
Remote sensing of the critical components of the prophet
Elevator networking is not Zhu Geliang after the event, but the governance is not sick ". For example, in the elevator door card is such a common fault, door sensors can monitor closed resistance size, if the normal closing current as long as 1 Amp, while the fault occurs before the current is often used 1.5 amps, is likely to is the elevator door pulley, a sliding chute memory in different things. According to reports, the elevator door is blocked some small trash and switch resistance will be increased, and the wisdom of the elevator can not only anticipate failure, but also accurate determination of which floor the elevator doors encounter obstacles.
Even more amazing is that the wisdom of the elevator networking can take the initiative to detect potential risks. The elevator brake, brake, for example, elevator things will be in the morning in the dead of night, to the "wisdom" of the elevator issued a directive, suspended kept unmanned, and brake test. The Internet of things to the elevator motor torque is applied, the simulation of elevator in case of overload lifting stressing, examine whether it in the designated floor stop. If the brakes a bit powerless, it should arrange "preventive maintenance", nip in the bud.
Maintenance is no longer "walking through the field"
With the new generation of elevator running state security monitoring system spread, the wisdom of the elevator plan in 2018 to 100000 more than. At the same time, the new system is changing the traditional mode of maintenance operation.
At present, over 90% of the elevator enterprises of after-sales maintenance, inspection, still rely on the a pen and a piece of paper the way were, pen and paper to record information can not be fast query, retrieval and analysis. Most of the time, some routine maintenance is often just a hook "touch on lightly, as a mere formality". While networking with the elevator supporting, it is the maintenance service management based on mobile terminal. Maintenance personnel are held similar to mobile phone terminal, on a handheld terminal system to distribute the task package "to accept, they to not to maintenance, on-site to how much time, step by step operation can go on the record. Even in a certain part of the surgery, the smart terminal supports camera upload, to the control staff live process, until the task completely compliance.
