Embodiment 1

[0035] Such as figure 1 As shown, in the elevator balance coefficient detector of the present invention, its measurement data processing system is composed of a tablet computer 9. The present embodiment selects Chiwei Hi8Pro dual-system 8-inch tablet computer, and the USB interface 6 of the tablet computer is connected to the speed controller via the communication module 5. The measurement system 1 and the power measurement system 3 constitute a communication connection between the measurement system and the data processing system.

[0036] In this embodiment, the speed communication circuit 2 and the power communication circuit 4 are RS232 interface communication circuits, the tablet computer 9 of the measurement data processing system is a USB interface, and the communication module 5 is a USB / RS232 interface converter, which realizes the connection between different communication interfaces. data transfer between.

[0037] figure 2 It is a block diagram of the communicat...

Embodiment 2

[0041] In this embodiment, both the speed communication circuit 2 and the power communication circuit 4 are USB interface communication circuits, and the communication module 5 is a USB one-to-two hub, which simplifies the data transmission system. Others are the same as in Example 1.

Abstract

The invention relates to an elevator balance coefficient detector. A measuring data processing system is composed of a tablet personal computer (9), power is supplied to a power measuring system (3) and a speed measuring system (1) by the tablet personal computer (9), and a USB interface (6) of the tablet personal computer is respectively connected with a power supply module (14) and a communication module (5) through plugs and wires; the other end of the power supply module (14) is respectively connected to a power supply circuit (16) of the power measuring system and a power supply circuit (15) of the speed measuring system; the other end of the communication module (5) is respectively connected to a communication circuit (4) of the power measuring system and a communication circuit (2)of the speed measuring system; and a TF card slot (8), an on-off key (10) and the USB interface (6) of the tablet personal computer are respectively connected with an SD card slot (7), an instrument switch (12) and a charging socket (12) in an instrument case. The elevator balance coefficient detector has the advantages of simple structure and convenience in operation, and the cost performance isimproved.

Description

technical field [0001] The invention relates to a detection instrument, more specifically, a special detection instrument for testing the balance coefficient of a traction elevator. Background technique [0002] China is the world's largest elevator producer and elevator consumer. About 700,000 new elevators are installed and used every year, of which traction elevators account for more than 90%. According to the requirements of the current elevator technical specifications, these newly installed elevators must be tested and adjusted for the balance coefficient, and can only be put into use after passing the test. Therefore, the detection of balance coefficient is a large-volume, wide-ranging and demanding technical work in the elevator industry. [0003] The current elevator technical standards and elevator inspection rules adopt the test method as follows: the car is loaded with 30%, 40%, 45%, 50%, and 60% of the rated load for the whole journey up and down, when the car ...
