Problems solved by technology
[0004] Because the load change in the actual operation of the elevator is related to the working environment, for the elevator with the same rated load, some elevators often work at full load, and some elevators often work at light load. If the same counterweight is used, the efficiency of the elevator will decrease. very low

Embodiment Construction
[0018] The following is combined with the specific figure 1, attached figure 2 The present invention is further described.
[0019] Figure 1 is The structural layout system diagram of the elevator in this embodiment.
[0020] figure 2 It is the structural diagram of the elevator load monitoring system.
[0021] like Figure 1 Shown: the elevator structural balance system is made up of car 2 and passenger 3, steel cable 4, motor 5, pulley 6 and counterweight 7. During the operation of the elevator, the weight of the car is composed of the weight of the car 2 and the passenger 3 . The weight of the car and the weight of the counterweight 7 form a balance system through the steel cable 4, the motor 5, and the pulley 6; when the weight values of the two are not equal, the difference is performed by the motor 5 to complete the running task; of course, in the actual elevator system The frictional resistance is also overcome by the motor doing work. The accompanying cabl...

An energy conservation design method for an elevator balance weight is provided with an elevator load monitoring system. The elevator load monitoring system is composed of an elevator car detection unit and an elevator data processing unit. The elevator car detection unit is composed of an elevator weighing sensor, an amplifier, an A / D converter, an upper level sensor, a lower level sensor and a power module. The elevator data processing unit is composed of a storage unit module, a CPU module and an LCD display module. The elevator weighing sensor, the upper level sensor and the lower level sensor respectively store collected elevator car load and stroke data into the storage device module of the elevator data processing unit. Statistic analysis is carried out on elevator load and stroke data in the storage device module according to months, seasons and years, the optimal elevator balance weight is calculated and displayed by the LCD module, operation personnel reasonably compensate the potential energy changes of an elevator car by observing displaying, and the satisfying energy conservation effect is achieved.
Description
technical field [0001] The invention relates to the field of elevators, in particular to an energy-saving design method for elevator counterweights. Background technique [0002] With the development of urbanization, the number of elevators has increased sharply, and the power consumption of elevators is huge. The national energy policy puts forward new requirements for energy-consuming products. Traction elevators are high-energy-consuming special equipment in buildings. The research on their energy consumption has become the basis for elevator energy efficiency evaluation, energy-saving supervision, and elevator design. [0003] In reality, when the elevator car rises or descends for a certain distance, the car and the counterweight each have a certain amount of reverse potential energy change, and the total mass of the car will also change due to the change in the number of passengers in the car, so even if The displacement of the car is the same, and the amount of chan...
