Description
Technical Field
The invention relates to a passenger conveying technology, in particular to a remote maintenance system of a passenger conveying device.
Background
With the rapid development of current city construction, the amount of passenger conveying equipment kept in each country is increasing day by day, so on the premise of ensuring high safety, it is also necessary to consider how to improve the maintenance efficiency of maintenance personnel, for example, under a closed environment such as a rail transit station, it is worth considering how to use one mobile terminal to perform maintenance operation on a plurality of lifting equipment.
The maintenance operation of common passenger conveying equipment of carrying on is maintained through the maintenance computer by maintenance personal at the scene, and at this moment, the computer lab that needs open passenger conveying equipment overhauls the apron, jumps into the computer lab, beats the door plant of switch board, need pass through dedicated communication cable, for example: the simulator or the writer is inconvenient to connect the maintenance computer and the control cabinet, the communication cable is fragile and cannot be pulled forcefully, and the normal use of the passenger conveying equipment cannot be guaranteed even if the communication cable is accurately connected. In order to ensure the safety of connection, patent document 1 (CN 104732323 elevator equipment maintenance management system) discloses a maintenance management system based on wireless tags, and patent document 2(CN 103955205 elevator controller remote debugging system and method) discloses a remote debugging system based on mobile terminal elevator controller. Although this maintenance system is designed in consideration of the security of connection, it cannot achieve a reduction in the work intensity of the maintenance personnel, and for example, chinese patent document CN 104732323 discloses a maintenance management system based on a wireless tag which performs authentication of the maintenance personnel and equipment by using a wireless tag similar to the NFC technology, but the range of use is very limited, and is only within 10 cm. If the technology is adopted, when the passenger conveying equipment is maintained, a maintenance worker still needs to open the machine room maintenance cover plate of the passenger conveying equipment, jump into the machine room, open the door plate of the control cabinet to perform remote maintenance operation, and the workload of the maintenance worker is almost equal to that of the maintenance worker who connects the communication cable. Dismantle the switch board door plant simultaneously and still have the insecure risk of assembly after the maintenance is accomplished, can influence the protection level of screen cabinet, lead to the screen cabinet to intake when outdoor environment uses and lead to inside electron device short circuit to influence passenger conveying equipment's normal use.
