fig. 2 is a flow chart of an energy saving method of an elevator communication system according to an embodiment of the present invention.
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 energy saving system of an elevator communication system according to an embodiment of the present invention includes a sensing module 30 and a timer 50 connected to the elevator communication system. An elevator communication system is used to overlay mobile network signals of an elevator car. The elevator communication system comprises a car unit 10 and a host unit 20. Wherein the car unit 10 moves with the elevator; the host unit 20 is stationary; the host unit 20 and the car unit 10 communicate wirelessly over the operating frequency band to achieve elevator car signal coverage.
Specifically, the sensing module 30 is connected to the car unit 10 and the host unit 20, respectively. The timer 50 is communicatively connected to the car unit 10.
In this embodiment, the sensing module 30 is configured to sense whether the elevator corresponding to the car unit 10 is in a running state or a stationary state. In particular, the sensing module 30 may be a radar sensor or an infrared sensor. For example, the radar sensor or the infrared sensor determines whether the state of the car unit 10 is in the running state or the stationary state by sensing whether the elevator car is moving. In other embodiments, the sensing module 30 may also be a gravity sensor. For example, the gravity sensor determines whether the elevator car is used by a user by sensing whether the weight of the elevator car is increased to determine whether the elevator is to be in a running state or a stationary state.
In the present embodiment, the timer 50 is used to calculate whether the elevator corresponding to the car unit 10 is in a stationary state for more than a first preset time period. The energy-saving control module 70 turns off the power amplifier of the car unit 10 after the elevator corresponding to the car unit 10 is in a stationary state for more than a first preset period of time. Thus performing energy-saving operation on the elevator communication system. Preferably, the timer 50 is also used for calculating whether the elevator corresponding to the car unit 10 is in a stationary state for more than a second preset time period. The energy saving control module 70 transmits a stop notification to the host unit 20 after the elevator corresponding to the car unit 10 is in a stationary state for more than a second preset period of time. Specifically, the stop notification is used to notify the host unit 20 to turn off its power amplifier. After receiving the stop notification of all the car units 10 corresponding to the host unit 20, the power amplifier of the host unit 20 is turned off, and the control frequency band of the host unit 20 is started. Specifically, the second preset time period is longer than the first preset time period.
It will be appreciated that the energy consumption of the control band of the car unit 10 or the host unit 20 is much less than the energy consumption of the operating band thereof. The operating frequency band of the car unit 10 or the host unit 20 includes a power amplifier operating at the car unit 10 or the host unit 20. Closing the power amplifier of the car unit 10 is to perform energy-saving operation on the elevator communication system. When the timer 50 is recording or calculating that the elevator corresponding to the car unit 10 is in a stationary state for more than 30 minutes in the second expected duration, the corresponding host unit 20 or the power amplifier which occupies the main energy consumption and is connected with the network signal of the car unit 10 is further turned off, and further energy is saved.
Further, the car unit 10 that has sent a stop notification to the host unit 20 turns on the power amplifier of the car unit 10 after sensing that the elevator corresponding to the car unit 10 starts to run; and transmits a start notification to the host unit 20 through the control band of the car unit 10. The start-up notification is used to notify the host unit 20 to turn on the power amplifier of the host unit 20.
The above embodiments illustrate the states that the car unit 10 and the host unit 20 are both in the open operating frequency band and in the closed control frequency band when the elevator is operating normally. In this case, after the elevator corresponding to the car unit 10 is in the stationary state for more than the second preset time period, the car unit 10 sends a stop notification to the host unit 20 through the operating frequency band notification energy saving control module 70, and the host unit 20 receives the stop notification through the operating frequency band. At this time, after the host unit 20 receives the stop notification, the control band is started while the working band is closed, so that after the elevator corresponding to the car unit 10 starts to run, the control band of the host unit 20 can receive the start notification sent by the car unit 10 while saving energy.
In other embodiments, since the control frequency band of the car unit 10 and the host unit 20 has low energy consumption, the control frequency band can be kept open while the operation frequency bands of the car unit 10 and the host unit 20 are opened during normal operation of the elevator. After the elevator corresponding to the car unit 10 is in a stationary state for more than a second preset time period, the car unit 10 can send a stop notification to the host unit 20 through the working frequency band notification energy-saving control module 70; the power saving control module 70 may also be notified of the stop notification to the host unit 20 through its control band. When the power is turned on, only the operating frequency band of the car unit 10 and the operating frequency band of the host unit 20 are turned off, and the control frequency band can be kept in an on state.
In the case where one host unit 20 in the elevator communication system covers a plurality of car units 10, that is, one host unit 20 and car units 10 of a plurality of elevator cars transmit network signals to each other to realize the coverage of a plurality of elevator car network signals; at this time, the energy-saving control module 70 is configured to detect that the power amplifiers of all the car units 10 covered by one host unit 20 are turned off, and then notify the timer 50 to start calculating whether the time for which all the elevators corresponding to the car units 10 are in the stationary state exceeds the second preset duration.
In an alternative solution, in the case where one host unit 20 covers a plurality of car units 10, when the host unit 20 receives the stop notification of all the corresponding car units 20, the power amplifier of the host unit 20 is turned off.
An energy saving method for an energy saving system of an elevator communication 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 host unit 20 and the car unit 10 perform wireless communication through a working frequency band so as to realize elevator car signal coverage;
s3, sensing whether the elevator corresponding to the car unit 10 is in a running state or a static state;
and S5, when the elevator corresponding to the car unit 10 is in a static state and exceeds a first preset time period, closing the power amplifier of the car unit 10. In this way, an energy-saving operation is performed on the elevator communication system.
Preferably, when the elevator corresponding to the car unit 10 is in a stationary state and exceeds a second preset time period, a stop notification is sent to the host unit 20. The stop notification is used to notify the host unit to turn off its power amplifier. It will be appreciated that the second predetermined time period is longer than the first predetermined time period.
When the host unit 20 receives the stop notification of all the corresponding car units 10, the power amplifier of the host unit 20 is turned off, and the control frequency band of the host unit 20 is started. As such, further energy savings are made to the elevator communication system.
Further, the car unit 10 which has sent a stop notification to the host unit 20 starts the power amplifier after sensing that the elevator corresponding to the car unit 10 starts to run; and transmits a start notification to the host unit 20 through the control band of the car unit 10. The start-up notification is used to inform the host unit 20 to turn on its power amplifier.
Further, after receiving the start notification, the host unit 20 immediately starts its power amplifier to bring the elevator communication system into a normal operation state. Preferably, the host unit 20 turns on its power amplifier, and after entering the working state, the control frequency band of the host unit 20 may be turned off, so as to further save energy.
The foregoing examples only illustrate preferred embodiments of the invention, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that modifications and improvements can be made without departing from the spirit of the invention, such as combining different features of the various embodiments, which are all within the scope of the invention.
