Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to a control device and a control method for controlling an air conditioner in an equipment room of a transformer substation. Background Art

[0002] Currently, for energy-saving reasons, air conditioners generally lack a power-on auto-start function. This means the air conditioner shuts down after a power outage and fails to restart automatically after a power-on restoration, requiring manual intervention. For substation equipment rooms, this characteristic, if not effectively corrected, would jeopardize the normal operation of the substation equipment room's electrical equipment and create significant additional workload for maintenance personnel. Therefore, a power-on auto-starter for the air conditioner with closed-loop, real-time detection and control is needed. This ensures reliable restart after each power outage, eliminating the risk of failure to restart the air conditioner in response to a power-on restoration, as with conventional infrared remote-controlled products. Summary of the Invention

[0003] The object of the present invention is to provide a control device and a control method for controlling the air conditioner in a substation equipment room.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a control device to ensure the normal operation of the air conditioner in the substation equipment room, comprising an air conditioner self-starting module, a remote control module and a mobile terminal module connected to the air conditioner in the substation equipment room, the air conditioner self-starting module is provided with a self-starting controller, the air conditioner in the substation equipment room is provided with an air conditioner receiver, and the remote control module is provided with a remote control device, wherein the self-starting controller includes a signal transmitter, a receiving window and an indicator light, the signal transmitter transmits a wireless signal to the air conditioner receiver, the receiving window receives the signal sent by the remote control device, one end of the remote control device is connected to a four-wire plug, the four-wire plug is connected to a cable, the other end of the remote control device is connected to a four-wire socket, the four-wire socket is connected to the air conditioner in the substation equipment room, one end of the self-starting controller is connected to a two-wire socket, and the other end of the two-wire socket is connected to the four-wire socket combination.

[0005] Furthermore, the self-starting controller is equipped with a remote controller, which sends learning and locking signals to the self-starting controller.

[0006] Furthermore, the signal transmitter is an infrared tube transmitter, and the distance between the infrared tube transmitter and the receiver is 30 mm to 500 mm.

[0007] Furthermore, the self-starting controller is installed on the air-conditioning surface of the substation equipment room.

[0008] Furthermore, the self-starting controller is a ZND-601 air conditioner power-on self-starting controller.

[0009] Furthermore, the remote control device is configured as a remote WiFi remote control timing switch.

[0010] Furthermore, the switch state of the remote WiFi remote control timer switch is synchronized with the mobile terminal module in real time.

[0011] Furthermore, the mobile terminal module receives, stores and processes the signal sent by the remote WiFi remote control timer switch in real time.

[0012] Furthermore, a control method of a control device includes the following specific steps:

[0013] Step (1): Remote control signal learning and lock setting;

[0014] Step (2): Automatic detection function setting remote control lock setting;

[0015] Step (3): remote control signal unlocking;

[0016] Step (4): Start and test the machine.

[0017] Furthermore, the signal learning method in step (1) is as follows: disconnect the power supply of the air conditioner and the starter (simulate a power outage), and then plug in the air conditioner and the starter. Within the first T1 time after powering on, the starter indicator light flashes once slowly for 1 second (if the indicator light flashes quickly, please release the remote control signal lock first). Within the T1 time, press the remote control switch key with the pre-set mode, temperature and wind speed to send the air conditioner start-up signal to the starter remote control receiving window. At this time, after the starter receives the signal, the indicator light stays on for 2 seconds, indicating that the signal learning is successful; the remote control signal locking method in step (1): after the starter is powered on and the above-mentioned signal learning operation is completed, if the indicator light is still in the state of flashing once slowly for 1 second, continue to press the remote control switch key to send the signal; if the starter receives the signal t1 times within the T2 time, the starter indicator light stays on for 2 seconds and then changes from flashing once per second to flashing twice per second, indicating that the signal locking is successful.

[0018] After adopting the above technical solution, the present invention has the following advantages:

[0019] 1. In the present invention, when power is restored after a power outage, the remote control module sends a start signal to the air conditioner self-starter module, and the air conditioner self-starter module sends a control signal to the air conditioner in the substation equipment room. The air conditioner in the substation equipment room starts and feeds back the information to the remote control module, forming a closed-loop real-time detection and control function to ensure that the air conditioner can be reliably restarted after each power outage. The remote control device is connected between the four-wire plug and the four-wire socket, and the four-wire plug is installed on the cable. The self-start controller is connected between the cable and the two-wire socket, and the two-wire socket and the four-wire socket are combined and connected together, so that the remote control device and the self-start controller can realize a streamlined hardware circuit solution, reduce the number of components, reduce the failure rate, and extend the service life, while also controlling power consumption and volume.

[0020] 2. The self-start controller is equipped with a remote control. By issuing commands through the remote control, the self-start controller can learn the settings of the substation equipment air conditioner before the power outage, and can lock the learning signal after completion.

[0021] 3. The signal transmitter is an infrared transmitter. The distance between the infrared transmitter and the receiver is 30mm to 500mm, so that the infrared transmitter can learn infrared commands from air conditioners of different brands.

[0022] 4. The self-start controller is installed on the surface of the air conditioner in the substation equipment room. In this way, the distance between the infrared and the pipe is limited. Installing it on the air conditioner in the substation equipment room can achieve more precise control.

[0023] 5. By setting the self-start controller to the ZND-601 air conditioner power-on self-starter, the ZND-601 air conditioner power-on self-starter will automatically start the air conditioner according to the preset state when the power is restored after a power outage, ensuring that the air conditioner will automatically start. It is suitable for unattended substations.

[0024] 6. By setting the remote control device as a remote WiFi remote control timer switch, the remote WiFi remote control timer switch has a simple and intuitive switch button, supports multiple groups of timing events, supports single, repeated, and delayed timing, and can be modified, deleted, and added at any time, which is safer and more convenient.

[0025] 7. Synchronize the on / off status of the remote WiFi remote control timer switch with the mobile terminal module in real time. This will facilitate real-time monitoring of the air conditioner.

[0026] 8. The mobile terminal module receives, stores and processes the signals sent by the remote WiFi remote control timer switch in real time, which is conducive to real-time monitoring of the air conditioner and remote response to emergency situations. The storage function can store data to facilitate the inspection of the number of self-start times of the air conditioner.

[0027] 9. The present invention also provides a control method for a control device as described in any of the above technical solutions, wherein the steps include: (1) remote control signal learning and lock setting; (2) automatic detection function setting remote control lock setting; (3) remote control signal unlocking; and (4) start-up and test operation. This control method can well implement the most streamlined hardware circuit solution; can effectively resist various electrical interferences, reduce the number of components, reduce the failure rate, extend the service life, and also control power consumption and volume.

[0028] 10. Through specific signal learning methods and remote control signal locking methods, the accuracy of control can be better guaranteed, which is conducive to further reducing the failure rate of the air conditioner in the substation equipment room, and at the same time further improving the service life of the air conditioner in the substation equipment room.

[0035] like Figure 1 、 2As shown, the present invention provides a control device for ensuring the normal operation of the air conditioner in the substation equipment room, including an air conditioner self-starting module, a remote control module and a mobile terminal module connected to the air conditioner in the substation equipment room, the air conditioner self-starting module is provided with a self-starting controller, the air conditioner in the substation equipment room is provided with an air conditioner receiver, the remote control module is provided with a remote control device, the air conditioner self-starting module is wirelessly connected to the air conditioner module in the substation equipment room, and the air conditioner module in the substation equipment room is wirelessly connected to the remote control module; when a power outage occurs and a power is restored, the mobile terminal module sends a control signal to the remote control module, the remote control module receives the signal for processing and sends a self-starting signal to the air conditioner self-starting module, the air conditioner self-starting module sends a self-starting signal to the air conditioner module in the substation equipment room, and performs self-starting control on the air conditioner, the air conditioner module in the substation equipment room transmits a signal to the remote control module after self-starting, the remote control module feeds back the signal to the mobile terminal module, forming a closed-loop control loop, detecting the control function in real time, and ensuring that the air conditioner can be reliably restarted after each power outage, thereby solving the problem that the substation equipment room cannot start the air conditioner in time after a power is restored when cooling is urgently needed.

[0036] Specifically, the air-conditioning self-starting module is provided with a self-starting controller 1. The self-starting controller 1 is a ZND-601 air-conditioning call self-starter and is equipped with a controller. The controller is used to issue instructions, which can enable the self-starting controller to learn the settings of the air-conditioning before the power outage and lock the learning signal after completion. The self-starting controller 1 includes a signal transmitter 13, a receiving window 11 and an indicator light 12. The signal transmitter 13 is used to transmit wireless signals to the air-conditioning receiver 4 of the air-conditioning 5 in the substation equipment room. The receiving window 11 is used to receive the signal sent by the remote control device 2; the signal transmitter 13 is an infrared tube device, and the distance between the infrared tube device and the receiver is 3cm-50cm, so it is installed on the surface of the air-conditioning 5 in the substation equipment room, so as to better learn the infrared instructions of air-conditioning of different brands and more accurately control the air-conditioning 5 in the substation equipment room; remote control Device 2 is set as a remote WiFi remote control timing switch, and the switch status is synchronized with the mobile terminal module in real time.

It can be modified, deleted, and added at any time, which is safer and more convenient, and is conducive to real-time monitoring of the air conditioner; one end of the remote control device 2 is connected to the four-wire plug 33, the four-wire plug 33 is connected to the cable 34, and the other end of the remote control device 2 is connected to the four-wire socket 32, the four-wire socket 32 ​​is connected to the substation equipment room air conditioner 5, one end of the self-start controller 1 is connected to the two-wire socket 31, and the other end of the two-wire socket 31 is connected to the four-wire socket 32 ​​in combination, so that the remote control device and the self-start controller can realize a streamlined hardware circuit solution, reduce the number of components, reduce the failure rate, extend the service life, and also control power consumption and volume.

[0037] Of course, the present invention also provides a control method for the control device in any of the above technical solutions, and the specific steps are as follows:

[0038] Step (1): Remote control signal learning and lock setting;

[0039] Step (2): Automatic detection function setting remote control lock setting;

[0040] Step (3): remote control signal unlocking;

[0041] Step (4): Start and test the machine.

[0042] With such a setting, this control method can well realize the most streamlined hardware circuit solution for speed display; it can effectively resist various electrical interferences, reduce the number of components, reduce the failure rate, extend the service life, and also control power consumption and volume.

[0043] Specifically, the signal learning method in step (1) is as follows: disconnect the power supply of the air conditioner and the starter (simulate a power outage), and then plug in the air conditioner and the starter. Within the first T1 period after powering on, the starter indicator light flashes once slowly per second (if the indicator light flashes quickly, please release the remote control signal lock first). Within the T1 period, press the remote control switch key with the pre-set mode, temperature and wind speed to send the air conditioner start signal to the starter remote control receiving window. At this time, after the starter receives the signal, the indicator light stays on for 2 seconds, indicating that the signal learning is successful. The remote control signal locking method in step (1) is as follows: after the starter is powered on and the above signal learning operation is completed, if the indicator light is still in the state of flashing once slowly per second, continue to press the remote control switch key to send the signal. If the starter receives the signal t1 times within the T2 period, the starter indicator light stays on for 2 seconds and then changes from flashing once per second to flashing twice per second, indicating that the signal locking is successful. The advantage of this setting is that through specific signal learning methods and remote control signal locking methods, the control accuracy can be better guaranteed, which is conducive to further reducing the failure rate of the air conditioner in the substation equipment room, and at the same time further improving the service life of the air conditioner in the substation equipment room; among them, T1 is 1 minute, T2 is 12 seconds, and t1 is 8 times.

[0044] Furthermore, the remote control signal learning and lock settings: After the starter is set to learn the remote control signal, the air conditioner can be controlled to start and operate according to the preset mode, temperature, and fan speed according to the learned remote control signal 2 minutes after power-on. The learning signal lock can be selected according to the use environment. Locking can prevent accidental pressing of the remote control in the first minute after an incoming call or in environments with infrared interference. Under normal circumstances, the signal lock can be disabled.

[0045] Automatic detection function setting and remote control lock setting: Disconnect the power supply of the air conditioner and starter and then plug in the power supply. In the second minute after power-on, the indicator light goes out and flashes twice for 5 seconds (the 30-minute automatic detection function is turned on). At this time, use the remote control to point at the starter and quickly press the remote control power button 8 times within 12 seconds to send a signal. After the starter receives the signal, the indicator light stays on for 2 seconds and changes from off and flashing twice for 5 seconds to off and flashing once for 5 seconds. The 30-minute automatic detection function is successfully turned off.

[0046] To unlock with the remote control signal: Disconnect the air conditioner and starter from the power source, then plug them back in. During the first minute after powering on, the starter indicator light will flash twice per second. Within 12 seconds, quickly press the remote control power button eight times to send a signal. Once the starter receives the signal, the indicator light will stay on for two seconds, changing from two quick flashes per second to one slow flash per second. This indicates successful unlocking.

[0047] Disabling the 30-minute automatic detection function applies to devices whose display doesn't change when the remote control's power button is pressed, as well as devices with remote controls without a display. This includes some Kelon air conditioners and infrared remote controls for TV set-top boxes. Because these remote controls send the same power-on and power-off codes, disabling the 30-minute automatic detection function is necessary.

[0048] Test Drive: After completing setup, disconnect the air conditioner and controller from the power supply (simulating a shutdown), then plug them back in. The controller will delay for two minutes. During the first minute, the indicator light will flash once per second at a moderate rate (if the signal is locked, the indicator light will flash twice per second at a rapid rate). In the second minute, the indicator light will pause for five seconds and then flash twice (if the 30-minute auto-detect function is disabled, the indicator light will pause for five seconds and flash once). After the delay, the controller will issue a power-on command, and the controller indicator light will turn solid, turning the air conditioner on. (If you hear feedback from the air conditioner but the air conditioner doesn't turn on, check the controller. The signal it's recording might not be a power-on signal, but a power-off signal. Follow step two to reset the controller.)

[0049] More specifically, the operating parameters are:

[0050] Adapter operating voltage: ~220V

[0051] Adapter USB interface voltage: +5V

[0052] Operating temperature: -20°C ~ +60°C

[0053] Infrared carrier frequency: 32KHz ~ 55KHz

[0054] In addition to the above preferred embodiments, the present invention has other implementation modes. Those skilled in the art can make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
