Problems solved by technology

[0002] Elevator is a multi-functional mechanical lifting equipment. According to the driving mode, it can be divided into traction type and forced type. The development of elevator technology is at a peak state. In order to improve the utilization rate of the site, most units or individuals have more A multi-storey building is selected, so a device is also needed to facilitate the transportation of goods up and down or construction. The elevator is widely used in multi-storey factories because of its advantages of convenient use, low cost, large load capacity, and convenient maintenance. However, in the process of operation and daily inspection and testing of existing elevator equipment, there is no relatively complete and efficient system for comprehensive measurement and control including safety monitoring, operation control and status detection.

Embodiment 1

[0023] like figure 1 As shown, an elevator comprehensive performance measurement and control system includes a measurement and control terminal, a monitoring system, a control system and a power supply system. Both the monitoring system and the control system establish signal connection with the measurement and control terminal. The control system includes an uplink and downlink control unit, a car door control unit, an emergency stop control unit, an inspection control unit and a landing door switch control unit, and the monitoring system includes a stress monitoring unit, a wire rope state monitoring unit, a landing door monitoring unit, a current The voltage monitoring unit and the car running state monitoring unit, in which: the stress monitoring unit monitors the stress state of the main stress mechanism of the elevator in real time; the steel wire rope state monitoring unit monitors the broken wire amount and diameter of the elevator steel wire rope; The switch state of ...

Embodiment 2

[0025] Further, the monitoring system also includes a door interlock monitoring unit and an electrical interlock monitoring unit, the door interlock monitoring unit monitors the safety switch state of the door interlock device, and the electrical interlock monitoring unit monitors the electrical interlock safety contact switch The state of the system is monitored, and the door interlock monitoring unit and the electrical interlock monitoring unit both feed back the monitoring results to the measurement and control terminal; there are several stress monitoring units, and there are several stress detection points on the main force-bearing mechanism of the elevator , each detection point is equipped with a stress monitoring unit; the wire rope state monitoring unit includes a wire rope flaw detector data processing base station and a wire rope flaw detection probe connected to each other, the wire rope flaw detector data processing base station is connected with the measurement and...

Embodiment 3

[0027] A four-core connection terminal is set in the stress monitoring unit to connect the full-bridge strain gauge, and then measure the full-bridge strain of the force-bearing mechanism. It has good temperature compensation performance and high measurement accuracy. At the same time, the stress monitoring unit is equipped with a 120 ohm selector switch; the stress monitoring unit adopts CAN bus to carry out monitoring data transmission, and connects with CAN to Ethernet adapter, and finally transmits the monitoring data through the network port; the pulse collector adopts RS485 bus for signal transmission, and communicates with 485 to Ethernet adapter connection, and finally the monitoring signal is transmitted through the network port; the data processing base station of the wire rope flaw detector and other monitoring units finally transmit the monitoring data to the measurement and control terminal through the network port, and the measurement and control terminal realizes ...

Abstract

The invention discloses a comprehensive performance measurement and control system of a lifter. The lift comprises a measurement and control terminal, a monitoring system and a control system, whereinthe monitoring system and the control system are in signal butt joint with the measurement and control terminal correspondingly, the control system comprises an uplink and downlink control unit, a lifter car door control unit, an emergency stop control unit, a maintenance control unit and a landing door switch control unit, wherein the monitoring system comprises a stress monitoring unit, a wirerope state monitoring unit, a landing door monitoring unit, a current voltage monitoring unit and a car running state monitoring unit. When the comprehensive performance measurement and control systemof the lift is applied, the comprehensive running state and performance of the lifter can be detected in real time, so that the daily management, the periodic inspection and the performance evaluation of the lifter are facilitated, the abnormal situation in the running process of the lifter can be found in time, and the safe and stable operation of the lifter can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a comprehensive performance measurement and control system of an elevator. Background technique [0002] Elevator is a multi-functional mechanical lifting equipment. According to the driving mode, it can be divided into traction type and forced type. The development of elevator technology is at a peak state. In order to improve the utilization rate of the site, most units or individuals have more A multi-storey building is selected, so a device is also needed to facilitate the transportation of goods up and down or construction. The elevator is widely used in multi-storey factories because of its advantages of convenient use, low cost, large load capacity, and convenient maintenance. In construction, but in the process of operation and daily inspection and testing of existing elevator equipment, there is no relatively complete and efficient system for comprehensiv...
