Keywords: construction elevator, TS1000, frequency converter, all-in-one machine I. INTRODUCTION The construction elevator is a kind of construction machinery that is used to carry people up and down along the guide rails. It is an important important vertical transportation in modern high-rise construction. Equipment plays an extremely important role in the construction of high-rise buildings. It plays an irreplaceable role in guaranteeing construction period and safety, reducing construction costs, and reducing labor intensity.
II. Development of Construction Elevators The most common type of construction elevators in China at present is the construction of SC gear racks and dual-purpose construction elevators, of which more than 90% are 1 to 2 tons.
The common lift is generally used as a contactor-relay control method, direct start and forced braking of mechanical brakes, large braking shock, large damage to the mechanical structure and mechanism, electrical components are also easily damaged, and easily caused in the lift The fall of materials not only affects the construction speed but also affects the benefits of construction companies. In particular, there are great potential safety hazards in the construction of dual-use elevators for people and goods.
With the continuous development of China's construction industry and the continuous improvement of the level of mechanization of construction, the requirements for the quality of construction elevators and the technical level of the whole machine are also increasing. The use of variable frequency speed control technology can realize the start-up acceleration and deceleration of the construction elevator and the stepless speed regulation of the braking process, reduce the impact of the motor on the mechanical system during the shutdown, and improve the smoothness and comfort of the construction elevator during operation. It extends the service life of the construction elevator and greatly improves the work efficiency. The application of frequency converters on construction elevators will become the development trend of the construction machinery industry.
III. Introduction of TS1000 Series Construction Elevator Drive One Machine Solution

It integrates high-performance vector frequency converters, braking units, lifting weight limiters, construction elevator logic control boards, leveling expansion cards and special operation consoles. Can provide a complete one-stop solution for manufacturers.
The product focuses on solving problems such as loose brake timing and leveling function of construction elevators. It has been optimized in terms of new floor learning, start-up acceleration control, leveling speed curve, interactive interface, etc. Industry-specific logic guarantees sequential control, Improves system safety and comfort, unique leveling control algorithms, and precise automatic leveling of lifts.
IV. Features and Benefits of TS1000 Construction Elevator Drive System (1) Modular design, one-stop solution, integrated high-voltage and low-voltage electrical cabinets integrated design, drive integrated special inverter, braking unit, lifting weight limiter, Construction elevator special logic control board, flat floor expansion card and GPS/GPRS monitoring system, etc.; customers in the low voltage electrical cabinet (main circuit breaker, main contactor, isolation transformer, loose contactor, lighting open) Optional, easy to integrate the elevator integrator, the system installation wiring is simple, convenient transportation, saving installation materials, labor and other costs.
(2) Intelligent operation platform, simple and intuitive operation The TS1000 dedicated operation platform integrates man-machine interface, floor calls, floor buttons, bells, sockets, operation buttons and control handles, with floor call function, call information and all running status of the elevator. The signals are clearly displayed on the large LCD screen. The intuitive man-machine interface reduces labor intensity and reduces hidden accidents.
(3) Built-in braking unit and lifting weight limiter, the customer does not need to configure the IGBT braking unit with built-in 1:1 power in the driver separately, and the direct connection of the braking resistor can achieve rapid shutdown.
The man-machine interface displays the current load weight KG. The weighing signal directly controls the drive to realize the limited-weight protection function, which is simple to use, high in accuracy, reliable and durable.
(4) Built-in GPS/GPRS communication port Built-in GPS/GPRS communication port, used for satellite positioning and remote monitoring, remote lock and unlock function, convenient for installment payment customer management (need special GPS module).
(5) Lifting special brake timing, safe and reliable lifting dedicated brake timing control, monitoring the inverter output frequency and output torque, using dual logic brake signal, so that the motor output sufficient torque when the lift starts or falls To prevent "slip hook", it also prevents the motor from impacting the mechanical system and causing vibration at the start of rising.
(6) The special S-curve acceleration and deceleration design for excellent start and stop comfort greatly improves start and stop comfort. When it is stopped, the inverter truly achieves "zero speed" braking, smooth leveling, small impact, reduced gear wear, and durability of the disc brake is greatly improved.

Waterproof design of the whole machine, rain proof experiment, IP54 waterproof rating.
(11)Easy installation, debugging and maintenance The special logic control board for elevators integrates the hardware protection logic of the elevator. The input and output have LED status indication and silk screen identification. The control terminal adopts cable or plug-in terminals, and the system is easy to install and connect; The modular design reduces installation man-hours, increases production efficiency, and reduces assembly failure rate. The system has a built-in dedicated control program. The inverter parameters can be set at factory setting. The system is simple to install, easy to debug, and simple and intuitive to maintain and maintain.
V. Brief introduction to installation and debugging 1. System wiring diagram 
When the main circuit and the control circuit are connected correctly, the system starts to debug. The debugging process is as follows: 
2. Setting parameters The TS1000 construction elevator driving integrated machine has solidified the elevator-specific parameters. Different types of elevators only need to set part of the specification parameters, and the other parameters can be operated at the factory value. The inverter's operation panel can conveniently set the elevator's specifications, encoder specifications, and motor specifications.
3, manual mode test peripheral inspection is completed, the power limit detection, limit switch, console buttons and LCD display is normal, according to the requirements set the construction elevator specifications, push the operating lever jog operation, determine the motor direction and three The phase sequence of the motor is the same. After the test is normal, the manual mode test runs.
4. Leveling mode floor learning and commissioning manual debugging is normal, through the TS1000 special console for floor self-study mode, manual control of the construction elevator operation through the operating lever, to the leveling floor of the floor, according to the "learned floor +1" method In order to learn new floors, the floor heights that have been learned are stored in the floor information. After the floor is learned, the console operation mode selects the leveling operation, which is to say, the leveling test run.
5. According to the national standard, the experimental debugging safety is the most important standard for construction elevators. When the system is commissioned, safety testing must be carried out in accordance with the national standard, and no-load commissioning, rated load debugging and overloading debugging shall be performed. Out-of-cage operation test, select the operation mode outside the cage in the console setting, and insert the cage outside the operation box to test; drop the experimental test, the same way is set to fall test mode, insert the drop test box to test.
