Embodiment 1

[0054] Please refer to figure 1 , is a schematic flow chart of a method for controlling a radiator fan of a villa elevator control cabinet in an embodiment, the method comprising:

[0055] Step 1, obtain the braking resistor power.

[0056] Obtain the inverter braking current and inverter bus voltage of the elevator to calculate the braking resistor power. During the operation of the elevator, the elevator needs to consume part of the electric energy on the braking resistor, and the braking resistor converts the electric energy into heat energy to consume energy, so the braking resistor will generate a lot of heat. Therefore, the temperature rise of the braking resistor will increase the temperature of the entire control cabinet, and the temperature rise of the control cabinet will cause the temperature of the internal components to rise, which will have an adverse effect on the reliable operation of the electronic components of the elevator. If the components If the tempera...

Embodiment 3

[0085] Please refer to Figure 5 , is a structural schematic diagram of a control system for a radiator fan of a villa elevator control cabinet in another embodiment, the system includes a power monitor 10 , a temperature sensor 20 and a controller 30 . The temperature sensor 20 is used to monitor the temperature of the radiator. The power monitor 10 is used to monitor the inverter braking current and inverter bus voltage of the elevator to calculate the braking resistor power. The controller 30 is used to obtain the estimated temperature of the radiator according to the temperature of the radiator and the power of the braking resistor, and is also used to control the motor 50 and the The working state of the radiator fan 40. When the estimated temperature of the radiator is greater than the first preset temperature, the controller 30 reduces the operating speed of the motor 50 and prolongs the stop time of the motor 50 . When the estimated temperature of the radiator is le...

Abstract

A control method and system for a radiator fan of a villa elevator control cabinet relate to the field of heat dissipation of elevator control cabinets. By obtaining the brake current of the frequency converter of the elevator and the bus voltage of the frequency converter to calculate the power of the braking resistor, and at the same time obtain the real temperature of the radiator to calculate the estimate of the radiator based on the power of the braking resistor and the real temperature of the radiator temperature, and then according to the estimated temperature of the radiator and the actual temperature of the radiator, the working status of the motor and the radiator fan used to drive the elevator is controlled, so that the control cabinet of the villa elevator can not only ensure the heat dissipation effect, but also reduce the elevator's temperature. Running noise.

Description

technical field [0001] The invention relates to the field of heat dissipation of an elevator control cabinet, in particular to a control method and system for a radiator fan of a villa elevator control cabinet. Background technique [0002] The elevator control cabinet is a device used to control the operation of the elevator. It is generally placed in the elevator machine room. The control cabinet of the machine room-less elevator is placed in the well. There are multiple functional components in the control cabinet. These functional components need to be dissipated from time to time, such as the braking resistor of the elevator. During the operation of the elevator, energy needs to be consumed on the braking resistor. Therefore, the control cabinet must be equipped with a radiator. The radiator includes cooling fins and The fan is used to improve the cooling effect of the radiator. [0003] In recent years, with the development of China's economy, villa elevators have bee...
