Description

A data center air conditioner remote control system and its realization method

technical field

The invention relates to the field of automatic starting of air conditioners, in particular to a system for automatically controlling the remote control of the air conditioner to remotely start the air conditioner and restoring to the working mode and setting parameters before the power failure when the air conditioner is powered off again and a system for setting parameters and a method for realizing the same.

Background technique

In the prior art, air conditioners in small data centers (computer rooms) generally use ordinary air conditioners based on cost considerations, while ordinary air conditioners do not have the function of self-starting when incoming calls are based on the consideration of energy conservation and environmental protection. Intervention to start. In order to ensure that the computer, network, communication and other equipment in the data center (computer room) can operate normally when the power grid is powered off, most computer rooms are equipped with an uninterruptible power supply (UPS), which is used to supply power to the above equipment when the power grid is powered off. The equipment continues to operate normally, and continues to operate when the power grid returns to its power supply state. Considering that the power grid is generally not powered off for a long time, and based on cost, air conditioners in small data centers (computer rooms) will not be equipped with intermittent power UPS to supply power. Ordinary air conditioners need manual intervention to restart. Therefore, if the air conditioner cannot be restarted after the power supply is restored, it will endanger the normal operation of other equipment in the data center (computer room). In order to restart the air conditioner in time after the power supply is restored, it will bring maintenance personnel Lots of extra work.

As we all know, after the ordinary air conditioner is powered off, all the information will be lost, and the setting mode and parameters of the last operation cannot be saved. When the power is turned off and the call comes back again, directly click the "ON/OFF" button on the main panel of the air conditioner to turn on the air conditioner, and the turned on air conditioner will operate according to the mode and parameters fixed by the air conditioner manufacturer.

In order to turn on the ordinary air conditioner of the data center (computer room) without manual intervention when the power is turned off again, the workload of maintenance personnel can be reduced, and the air conditioner can be operated according to the mode and parameters set before the power failure. The technical solutions currently used are:

(1) Add an air conditioner power-off memory module on the air conditioner host side, which is used to update and learn the remote control signal synchronously. When the power is turned off again, the air conditioner will be automatically restarted with the learned remote control signal, and its signal input/output line and the remote control receiver on the air conditioner host It is used to transmit the remote control signal received by the host of the air conditioner in real time to the power-off memory module of the air conditioner to learn, update and save, and to output the saved remote control signal to the host of the air conditioner when the power is cut off again. Control the air conditioner to restart. The defect is that to dismantle the main unit of the air conditioner, you must invite professionals to install it at your door, which is troublesome, and because the air conditioner code and carrier frequency cannot be consistent between manufacturers, so: the additional air conditioner power-off memory module must be compatible with the air conditioner model, otherwise, the power will be cut off. The air conditioner cannot be automatically restarted correctly when the phone is called again later. Such as: general Gree air conditioner power-down memory module, Midea air-conditioning power-down memory module, air-conditioning unit Haier air-conditioning power-down memory module, etc. Therefore: an air conditioner power-off memory module is added to the main unit of the air conditioner, which is more suitable for purchase and customization. When an air conditioner with an air conditioner power-off memory module is added, and the data center (computer room) is moved to be another one that does not need to be powered off and restarts when the power is turned off again, the power-off memory module of the air conditioner has to be removed from the host side of the air conditioner, which is troublesome.

(2) Add an electric air conditioner automatic starter outside the main unit of the air conditioner, so as to overcome the problem of disassembling the air conditioner to modify the circuit and welding the circuit in the above (1). The learning method is used to pre-store the parameters such as the mode opening mode of the remote control of the air conditioner. When the power is cut off again, the automatic starter of the air conditioner will automatically restart the air conditioner with the learned remote control signal. , therefore: the parameters of the remote control air conditioner restart signal sent by the automatic starter of the incoming air conditioner are not necessarily the remote control signal parameters modified by the user halfway. study. Because its infrared receiver is not the same as the air conditioner host infrared receiver, in order to correctly start the air conditioner when the incoming call comes back after a power failure, most of the incoming air conditioner automatic starters use the pre-stored method to learn the air conditioner remote control. Remote control power-on signal. Such as: JCD-ZQ8.0 air conditioner self-starting controller for incoming calls, Western France air conditioner automatic starter, AC-001 infrared air conditioner starter, etc.

(3) It is also recorded in the patent literature that it can overcome the defects in the above (1) and (2) by adding an incoming call detection circuit outside the main unit of the air conditioner to control the "on/off" button action on the remote control of the air conditioner when an incoming call occurs, and send a remote control signal to turn on the air conditioner and make the air conditioner. Re-run according to the mode and parameters set by the user on the air conditioner remote control, but both cannot effectively control the opening of the air conditioner, and it is inconvenient for the user to take the air conditioner remote control. For example, a lever automatic starter with the application number of 201010518807.6, after detecting an incoming call, it uses the lever method to push the "on/off" button on the air conditioner remote control, except that the lever contact is difficult to align the "on/off" button on the air conditioner remote control. ” button, and it is inconvenient for users to take and place the remote control of the air conditioner, there is also a single hit on the “on/off” button on the remote control of the air conditioner, which cannot effectively control the air conditioner to turn on. Another example is an air conditioner self-starter with an application number of 201920295336.3. After detecting an incoming call, it uses a wired method to control the additional switch connected in parallel with the "on/off" on the air conditioner remote control to turn on, unless there is a user taking the air conditioner remote control. In addition to the inconvenience, there is also a switch connected in parallel with the "on/off" on the remote controller of the air conditioner that is added for one-time control, which cannot effectively control the opening of the air conditioner.

Detailed ways

As shown in FIG. 1, a data center air conditioner remote control system includes an incoming call monitoring control circuit 200, an air conditioner remote control 100, and a power supply module 300 obtained from an air conditioner power supply 400; Connect the power input of the air conditioner; operate the "on/off" button 101 of the air conditioner remote control 100 to send the set operating mode and parameters and switch the air conditioner remote control signal; the air conditioner remote control 100 is additionally provided with a switch and an "on/off" button 101 switches the reed switches 6 connected in parallel, and the output of the incoming call monitoring control circuit 200 is magnetically connected to the reed switches 6 in the air conditioner remote control 100, instead of manually operating the “on/off” button 101 of the air conditioner remote control 100.

The incoming call monitoring control circuit 200 includes a control processor connected with a temperature sensor 2 , a clear button 3 , an electromagnet drive circuit 4 , a remote control module 7 for detecting an air conditioner, an indicator light 8 , a buzzer 9 and an electronically controlled tripping device 10 . The unit 1, the electromagnet 5; the electromagnet drive circuit 4 is connected to the coil of the electromagnet 5, and the electromagnet 5 is connected with the reed switch 6 added in the air conditioner remote control 100 by magnetic force.

The reed switch 6 is a normally open type, the reed switch 6 is arranged on the inner side of the rear cover at one end of the air conditioner remote control 100 in the length direction, and the reed switch 6 is connected in parallel with the "on/off" button 101 switch through a lead wire. . The on/off button 101 of the air conditioner remote control 100 is replaced by the manual operation of the "on/off" button 101 of the remote controller 100 of the air conditioner.

The air conditioner remote control 100 is an air conditioner remote control corresponding to the air conditioner switch, operation mode and parameter setting and adjustment, and a reed switch 6 connected in parallel with the switch of the "on/off" button 101 is added. The remote control corresponds to the air conditioner switch, operation mode and parameter setting and adjustment of the air conditioner remote control. When the operation mode and parameters are selected, the "on/off" button 101 is operated to turn on the air conditioner and the selected operation mode is sent together. and parameters. Since the "on/off" button 101 is a multiplexing button, the signals for remote power on and off are alternately switched.

The air conditioner remote control 100 is placed at the set position on the incoming call sending table with the front side facing up and the emission window facing outward. The set position is an inclined plane whose slope and direction can be adjusted. For the groove of the remote control 100, adjust the slope and direction so that the length of the slope is directed to the infrared receiving window of the air conditioner. The height of the incoming call sending table is lower than the height of the air conditioner infrared receiving window, and the linear distance from the air conditioner infrared receiving window is less than 3, so that the air conditioner can effectively receive the remote control signal sent by the air conditioner remote control 100 on the incoming call sending table.

The electronically controlled tripping device 10 is connected to the input of the control processor unit 1. The electronically controlled tripping device 10 is used to lock the remote control 100 of the air conditioner on the counter to send incoming calls during a power outage, and to trip the remote control for the air conditioner on the counter during power-on. The controller 100 can move the remote controller 100 of the air conditioner on the transmission table for incoming calls. During a power failure, the electronically controlled release device 10 locks the air conditioner remote control 100 on the incoming call sending table under the action of a spring, thereby effectively restricting the movement of the air conditioner remote control 100 on the incoming call sending table; during power-on, the control process The controller unit 1 sends a control signal to the electronically controlled tripping device 10 to control its lock and trip to send the remote control 100 of the air conditioner on the counter for incoming calls, so that the user can move the remote control 100 of the air conditioner on the counter for incoming calls. If the user can consciously avoid moving the air conditioner remote controller 100 during a power outage, the electronically controlled tripping device 10 can be removed, that is, the electronically controlled tripping device 10 is not provided.

The detection air conditioner remote control module 7 is connected to the control processor unit 1, and is used for the control processor unit 1 to detect whether the air conditioner remote control 100 exists on the set position of the incoming call transmission table by detecting the air conditioner remote control module 7 during the power-on period, If the air conditioner remote control module 7 detects an existence signal, it is determined that the air conditioner remote control 100 is at the set position of the incoming call sending table; otherwise, it is determined that the air conditioner remote control 100 is moved.

The detection air conditioner remote control module 7 is a photoelectric switch (photoelectric sensor), or a Hall switch and a magnet.

When detecting that the air conditioner remote control module 7 adopts a photoelectric switch, set the photoelectric switch at the set position of the air conditioner remote control 100 on the incoming call transmission table, and use the object to be detected to block or reflect the light beam to detect whether there is an object. When it is detected that an object (air conditioner remote control 100) is put in, a state is sent to the control processor unit 1 to determine that the air conditioner remote control 100 is at the set position, and when no object (air conditioner remote control 100) is detected to be put in When entering, another state is input to the control processor unit 1, and it is recognized that the air conditioner remote control 100 is moved. The transmitter in the photoelectric switch is connected with the output of the control processor unit 1 , and the receiver in the photoelectric switch is connected with the input of the control processor unit 1 . The selected photoelectric switch of the present invention detects that the air conditioner remote control 100 is put in, its receiver outputs a high level, and when it does not detect that the air conditioner remote control 100 is put in, its receiver outputs a low level.

When it is detected that the air conditioner remote control module 7 adopts a Hall switch and a magnetic steel, the magnetic steel is added in the air conditioner remote control 100. In order to prevent the reed switch 6 from being interfered by the magnetic steel, the magnetic steel is placed in the air conditioner remote control. On the inner side of the rear cover without the 6 end of the reed switch in the length direction of the 100, on the setting position where the air conditioner remote control 100 is placed on the incoming call transmission table, the magnetic steel set in the air conditioner remote control 100 corresponds to the Hall switch embedded in the Hall switch. The output is connected to the control processor unit 1 input. When the Hall switch detects the magnetic field, it outputs a state to the control processor unit 1, and it is determined that the air conditioner remote control 100 is in the set position; when no magnetic field is detected, it outputs another state to the control processor unit 1, It is recognized that the air conditioner remote controller 100 has been moved. Therefore, when the Hall switch and the magnetic steel are used as the detection air conditioner remote control module 7, during the power-on period, when the Hall switch detects the presence of the air conditioner remote control signal, the placement direction of the air conditioner remote control 100 is also limited at the same time. Therefore, in the present invention, it is preferable to use a Hall switch and a magnetic steel to detect the remote control module 7 of the air conditioner. The Hall switch selected by the present invention outputs a high level when detecting a magnetic field, and outputs a low level when the magnetic field is not detected; that is, when it is detected that the air conditioner remote control 100 is put in, the Hall switch outputs a high level, and no air conditioner is detected. When the remote controller 100 is put in, its Hall switch output is low.

The present invention requires the user to set and adjust the operation mode and parameters of the air conditioner through the air conditioner remote control 100, and keep the operation mode and parameter setting and adjustment of the air conditioner on the air conditioner remote control 100 unchanged, place the air conditioner remote control 100 on the Call sending platform.

If the air conditioner is not turned on at this time, it is necessary to manually turn on the air conditioner and set the operation mode and parameters through the air conditioner remote control 100 . The lighted indicator light 8, if it is recognized that the air conditioner remote control 100 is moved during the control process of the reed switch 6, the lighted indicator light 8 will be turned off, otherwise, the control process of the reed switch 6 will naturally end when to turn off the lit indicator 8.

The buzzer 9 is connected with the output of the control processor unit 1, and is used to send out a first prompt sound when moving the air conditioner remote controller 100 in the control process of the reed switch 6 after an incoming call, and for the reed switch 6. After the natural end of the control process and the operation of the clear button 3 to terminate the first prompt sound, the remote control 100 of the air conditioner is monitored to be moved during the power-on period, and the buzzer 9 emits a second prompt sound, and the second prompt sound will not be monitored until the remote control of the air conditioner is detected. Terminates when the device 100 is put in place. That is, when the indicator light 8 is off and the buzzer 9 has no prompt sound, it is detected that the air conditioner remote control 100 is moved, and the buzzer 9 emits a second prompt tone. 100 stops when placed in place. In the present invention, the first prompt tone adopts the continuous long tones of "di...di..."; the second prompt tone adopts the continuous short tones of "di di...".

The clear button 3 is a tact switch button, and the clear button 3 is connected to the input of the control processor unit 1, and is used to clear the control processor unit 1 in the process of controlling the reed switch 6, and recognizes that the air conditioner remote control 100 is activated. The buzzer 9 emits the first prompt sound when moving. The control processor unit 1 controls the reed switch 6 after the power is turned off. During the control process of the reed switch 6, when the air conditioner remote control module 7 recognizes that the air conditioner remote control 100 is moved, the buzzer 9 is activated. Enter the first prompt tone. While the buzzer 9 outputs the first prompt tone, when the air conditioner remote control module 7 recognizes that the air conditioner remote control 100 is restored (placed in the original position), click the clear button 3, and the buzzer 9 stops outputting the first prompt sound.

The input of the electromagnet drive circuit 4 is connected to the output of the control processor unit 1 , and the output of the electromagnet drive circuit 4 is connected to the coil of the electromagnet 5 . The control processor unit 1 outputs through the electromagnet drive circuit 4 to control the electromagnet 5 to work, and when the control processor unit 1 outputs through the electromagnet drive circuit 4 to control the electromagnet 5 coil to be energized, the electromagnet 5 generates magnetic force; When the output of the device unit 1 is controlled by the electromagnet drive circuit 4 and the coil of the electromagnet 5 is powered off, the electromagnet 5 loses its magnetism, that is, the electromagnet 5 has no magnetic force.

The electromagnet 5 is a sucker type electromagnet. When the coil of the electromagnet 5 is energized, a magnetic attraction force is generated. The electromagnet 5 is magnetically connected with the reed switch 6 added in the air conditioner remote control 100, and the electromagnet 5 is used to specifically control the switch on and off of the reed switch 6. When the coil of the control electromagnet 5 is energized, a The magnetic force makes the switch of the reed switch 6 turn on. When the coil of the control electromagnet 5 is powered off, it will lose its magnetism and the switch of the reed switch 6 will be turned off. Since the electromagnet 5 is a sucker type electromagnet, so that a magnetic force can be generated in a certain area, it is convenient to install the electromagnet 5 and the reed switch 6 .

At the set position where the air conditioner remote control 100 is placed on the incoming call sending table, the electromagnet 5 is embedded in the reed switch 6 corresponding to the additional reed switch 6 in the air conditioner remote control 100 .
