Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, an elevator signal coverage system in an energy saving system of an elevator signal coverage system according to an embodiment of the present invention is used for covering a mobile network signal of an elevator car. The elevator signal coverage system comprises a car unit 10 moving with the elevator and a host unit 20 communicating mobile network signals with the car unit 10 and stationary. As can be appreciated, the car unit 10 is mounted to an elevator car; both the host unit 20 and the elevator drive motor 30 driving the elevator car are mounted in the elevator machine room or at the top of the hoistway in which the elevator car is running. Specifically, the car unit 10 communicates wirelessly with the host unit 20 through the operating frequency, thereby achieving elevator car signal coverage. The drive motor 30 of the elevator has a power cord for supplying power thereto.
The energy saving system of the elevator signal coverage system includes a current sensing module 50, a timer 60, and an energy saving control module 70. In this embodiment, one end of the current sensing module 50 is connected to a power line for supplying power to the driving motor 30 of the elevator, so as to sense the current variation condition of the power line for supplying power to the driving motor 30; and the current sense module 50 is integrated into the host unit 20. The timer 60 is connected to the host unit 20 of the integrated current sensing module 50 and the energy saving control module 70 at both ends, respectively. The current sensing module 50 integrated with the host unit 20 monitors whether the current of the driving motor 30 of the elevator corresponding to the car unit 10 is changed. The timer 60 is used to calculate whether the time during which the current of the driving motor 30 is not changed exceeds a preset time. The energy saving control module 70 is used for sending a stop notification to the corresponding car unit 10 of the elevator when the time that the current of the driving motor 30 is not changed exceeds the preset time. The stop notification is used to notify the car unit 10 to turn off its power amplifier. After the car unit 10 turns off its power amplifier, the car unit 10 subsequently performs wireless communication by controlling the frequency.
In this embodiment, the other end of the current sensing module 50 is connected to the host unit 20, and the host unit 20 knows whether the current in the power line of the elevator driving motor 30 is changed or not through the direct feedback of the current sensing module 50. It will be appreciated that the current in the power cord of the elevator drive motor 30 will become greater when the elevator car is in operation. For example, if the current sensing module 50 monitors a change in current in the power cord of the elevator drive motor, then the elevator car is deemed to be running and the network signal coverage system of the elevator car needs to remain operational. Otherwise, if the current sensing module 50 monitors that the current in the power line of the elevator driving motor has not changed, it is determined that the elevator is in a stationary state without a user.
Further, the energy-saving control module 70 is further configured to turn off the power amplifier of the host unit 20 after the host unit 20 sends a stop notification to all the corresponding car units 10. The car unit 10 also turns off its power amplifier upon receiving the stop notification. In this way, the power amplifiers of the host unit 20 and the car unit 10 are turned off, and energy saving of the elevator signal coverage system is achieved.
It will be appreciated that both the car unit 10 and the host unit 20 have an operating frequency band and a control frequency band. Wherein the operating frequency band of the car unit 10 or the host unit 20 includes the operation of the power amplifier. The power amplifier is a main power consumption part of the elevator signal coverage system, and the power consumption of the working frequency bands of the car unit 10 and the host unit 20 is large. In this embodiment, when the elevator is operating normally, the operating frequency band and the control frequency band of the car unit 10 and the host unit 20 may be both in the on state. When the energy-saving operation is performed, the operating frequency bands of the car unit 10 and the host unit 20 are closed, and the control frequency bands thereof are kept open for communication with each other. For example, when the host unit 20 monitors that the drive motor current of the elevator corresponding to the car unit 10, for which the stop notification has been sent, changes, the host unit 20 can send a start notification to the car unit 10 through its control frequency band. The start notification is used to notify the car unit 10 of turning on its power amplifier. In this case, the control band of the car unit 10 is turned on, and a start notification transmitted from the control band of the host unit 20 can be received.
In this embodiment, the energy-saving control module 70 is configured to send a start notification to the car unit 10 through the control frequency band of the host unit 20 when the host unit 20 monitors that the current of the drive motor 30 of the elevator corresponding to the car unit 10 that has sent the stop notification changes. After receiving the start notification, the car unit 10 immediately starts its power amplifier.
Preferably, after the car unit 10 starts its power amplifier, the control frequency of the car unit 10 is turned off, further saving energy.
In another embodiment, when the host unit 20 monitors that the current of the driving motor 30 of the elevator corresponding to the car unit 10, which has sent the stop notification, changes, the host unit 20 may first turn on its power amplifier and send a start notification to the car unit 10, notifying the car unit 10 to turn on its power amplifier. In this case, the energy saving control module 70 is used to turn on the power amplifier of the host unit 20 when the host unit 20 monitors that the current of the drive motor 30 of the elevator corresponding to the car unit 10, which has sent the stop notification, is changed. And at the same time transmits a start notification to the car unit 10 through the control band of the host unit 20. It will be appreciated that a start notification may also be sent to the car unit 10 through the operating band of the host unit 20 after the power amplifier of the host unit 20 is started. In this way, both the power amplifiers of the host unit 20 and the car unit 10 are turned on, and the normal coverage of the network signals of the elevator signal coverage system is restored.
An energy saving method of an energy saving system of an elevator signal coverage system according to an embodiment of the present invention will be described in detail with reference to fig. 1 and 2, and includes the following steps:
s1, the car unit 10 and the host unit 20 perform wireless communication through a working frequency band, so that the signal coverage of the elevator car is realized;
s3, monitoring the current of a driving motor of the elevator corresponding to the car unit 10 through the host unit 20;
s5, if the host unit 20 monitors that the current of the driving motor 30 is not changed and exceeds the preset time, a stop notification is sent to the corresponding car unit 10 of the elevator. The stop notification is used to notify the car unit 10 to turn off its power amplifier. The car units then communicate wirelessly by controlling the frequency.
Further, after the host unit 20 sends a stop notification to all the car units 10 corresponding thereto, the power amplifier of the host unit 20 is turned off. At this time, the host unit 20 may transmit a stop notification to the car unit 10 through the operating band or the control band. It will be appreciated that the car unit 10 corresponds to a stop notification sent over its operating frequency band to the receiving host unit 20 operating frequency band. The car unit 10 corresponds to a stop notification transmitted through its control band reception host unit 20 control band.
In the present embodiment, when the host unit 20 monitors that the current of the drive motor 30 of the elevator corresponding to the car unit 10, which has sent the stop notification, changes, a start notification is sent to the car unit 10 through the control band of the host unit 20. The start notification is used to notify the car unit 10 of turning on its power amplifier. In this case, the host unit 20 may first turn on the power amplifier of the car unit 10, and then turn on the power amplifier of the host unit 20 itself. Preferably, the car unit 10 starts the power amplifier, and after the working frequency band is started, the control frequency band of the car unit 10 can be closed, so that further energy saving is achieved.
In an alternative embodiment, when the host unit 20 monitors that the current of the drive motor 30 of the elevator corresponding to the car unit 10, which has sent a stop notification, changes, the power amplifier of the host unit 20 is turned on; and transmits a start notification to the car unit 10 through the control band of the host unit 20. After receiving the start notification, the car unit immediately starts the power amplifier. That is, the host unit 20 starts the power amplifier, then makes the car unit 10 start the power amplifier, and then sends a start notification to the car unit 10 to start the power amplifier of the car unit 10.
