Embodiment 1

[0025] Embodiment one ( figure 1 ), the PLC I (2) is composed of two CPUs, CPU1 (2.1) and CPU2 (2.2), the CPU1 (2.1) and CPU2 (2.2) can form a redundant or hot standby type, and the CPU1 ( 2.1) and CPU2 (2.2) keep data synchronization at all times, once a CPU breaks down, only an alarm will be issued, and the other CPU will continue to keep the monitoring system in the elevator machine cluster described in the present invention in a good working condition; in practical applications, The PLC I (2) can also be composed of a CPU, namely CPU1 (2.1), see Embodiment 2 ( figure 2 ).

[0026] The difference between embodiment one and two is also that, figure 1 Among them, seven of the PLC III (6.1b~6.7b) are remote substations of the PLC I (2), or small PLCs of the same series as the PLC I (2), for example, the PLC I ( 2) If it is Siemens S7-1500 series, then the 7 mentioned PLC III (6.1b~6.7b) can be Siemens S7-1200 series; figure 2 Among them, the 7 PLC III (6.1b~6.7b) can als...

Abstract

The invention belongs to hoists and a control technology thereof and provides a centralized monitoring system for a mine hoist cluster, which can simultaneously perform centralized monitoring on N hoisting equipment in the same mine by only arranging one to two monitoring personnel in each shift. The system mainly comprises a network switch, a PLC (Programmable Logic Controller), a server, an engineer station, N groups of human-computer interfaces, N field monitoring boxes and the like, wherein the man-machine interfaces, the field monitoring boxes and the lifting equipment are in one-to-one correspondence; a two-layer network is formed based on a network switch, a lower layer is a ring network of optical cables, an upper layer is a star network of shielding network cables, networked communication is formed between the ring network and the star network, and monitoring personnel conduct remote centralized monitoring and control on N lifting devices through corresponding human-computer interfaces. Sensors used for detecting running states of the devices are additionally arranged on the using site of the N lifting devices, no driver is arranged, unattended operation is achieved, labor cost is saved, working efficiency of the lifting system is improved, and social and economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of hoists and their control, and specifically proposes a cluster monitoring system for mine hoists. Background technique [0002] The traditional mine hoist usually needs to be equipped with two drivers (winners) and one deputy (winner) per shift. It is calculated as four shifts per day. For one mine hoist, at least eight winches are required. If a mine has N mine hoists If the machine is used, at least 8N winches are equipped, which is not a small expense for the mine. [0003] The unattended mine hoist can save winch workers and expenses, and also improve the efficiency and safety of the hoisting system. The problem is that once the equipment fails or requires personnel intervention, if it is purely unattended, the response may not be fast enough, which will also affect production. [0004] The present invention is based on the PLC two-wire network control of the existing mine hoisting electric control e...
