So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

An embodiment of the present application provides an information interaction method, and fig. 1 is a first flow diagram of the information interaction method in the embodiment of the present application.

The information interaction method shown in fig. 1 is applied to an air conditioner, the air conditioner comprises a main machine and a sub machine, the main machine comprises a first socket, and the sub machine comprises a second socket corresponding to the first socket. To this end, the present application provides a structure diagram of an air conditioner, fig. 2 is a schematic diagram of a structure of the air conditioner in the embodiment of the present application, and as shown in fig. 2, the structure of the air conditioner includes an upper air conditioner main component and a lower expansion functional component, the upper air conditioner main component realizes basic functions of cooling and heating of the air conditioner, the lower expansion functional component includes a lower air duct air inlet side portion and an upper air duct air outlet side portion, air duct cavities of the upper air duct and the lower air duct are communicated, the lower air duct air inlet side portion includes an air inlet valve assembly, the upper air duct air outlet side portion includes an installation cavity (including a first socket) and an air outlet valve assembly of one or more sub-machines (also referred to as plug-and-play functional modules), the sub-machines can be pushed and pulled out (plug-and-play) in a drawer-type manner, and the plurality of sub-machines share an air duct after being all inserted. Illustratively, the submachine at least comprises a HEPA filter screen device, an ion generator device, a humidifying device or an oxygen generating device. Wherein, the HEPA filter screen device is used for removing fine particles (including fine particles with the diameter less than 2.5 microns) in the air; the ion generator device generates negative ions by utilizing a method of boosting power frequency voltage to required voltage by using a high-voltage transformer, and releases the negative ions into air to purify the air; the humidifying device can increase the content of moisture in the air so that the air becomes humid; the oxygen generator can increase the oxygen content in the air, increase the oxygen content of blood through human respiration, and make people have better spirit.

As shown in fig. 1, the information interaction method may include the specific steps of:

step 101: when the sub-machine is determined to be installed in place on the main machine and the output voltage and the output current of any one communication socket meet communication conditions when the first communication socket is connected with the second communication socket, the main machine is controlled to send a first instruction to the sub-machine through an information transmission line formed by the first communication socket and the second communication socket;

here, the first socket on the master unit includes a first communication socket, and the second socket on the slave unit includes a second communication socket.

It should be noted that when the first communication jack on the host computer is connected with the second communication jack on the sub computer, the contact resistance (including the shrinkage resistance and the film resistance) exists at the position of the communication contact, and the communication contact may deform due to long-time plugging and unplugging operations, and may also be oxidized due to environmental pollution, resulting in an increase in the contact resistance, and the situation that the film resistance cannot be punctured, and further resulting in a failure in information interaction may occur. In order to avoid the situation of information interaction failure, after the submachine is determined to be installed in place on the main machine, when the connection between the first communication jack and the second communication jack is detected in advance, whether the output voltage and the output current of the first communication jack or the second communication jack meet the communication condition is determined, and when the communication condition is determined to be met, the film resistor is directly punctured when the first communication jack and the second communication jack are contacted, so that the information interaction between the main machine and the submachine can be ensured; otherwise, when the communication condition is determined not to be met, the film resistor cannot be broken down when the first communication jack is contacted with the second communication jack, namely, information interaction cannot be carried out between the host machine and the submachine.

In some embodiments, the first outlet further comprises a first power supply outlet, and the second outlet further comprises a second power supply outlet; the first communication socket is connected with the first voltage and current detection module, and the second communication socket is connected with the second voltage and current detection module; after the submachine is determined to be installed in place on the main machine, the method further comprises the following steps: the control host computer supplies power to the submachine through the first power supply socket and the second power supply socket; the control host sends a first self-checking signal to the first voltage and current detection module, and the first voltage and current detection module is used for detecting whether the output voltage and the output current of the first communication socket meet communication conditions; or, the sub-machine is controlled to send a second self-checking signal to the second voltage and current detection module, and the second voltage and current detection module is used for detecting whether the output voltage and the output current of the second communication socket meet the communication condition.

That is, the first voltage and current detection module is installed on the host side, the first voltage and current detection module is used to detect whether the output voltage and the output current of the first communication socket satisfy the communication condition, and when the communication condition is determined to be satisfied, the information interaction between the host and the slave machine is described, wherein the host can send command information (i.e. the first command mentioned above) to the slave machine through the information transmission line formed by the first communication socket and the second communication socket.

Or, a second voltage and current detection module is installed on the slave unit side, the second voltage and current detection module is used for detecting whether the output voltage and the output current of the second communication socket meet the communication condition, and when the communication condition is determined to be met, the host unit and the slave unit can perform information interaction, wherein the host unit can send instruction information (namely the first instruction) to the slave unit through an information transmission line formed by the first communication socket and the second communication socket.

For example, when the submachine is an oxygen generator, the first command may be an oxygen generation command.

In some embodiments, the communication conditions include: the output voltage of the first communication socket is greater than a preset voltage threshold, and the output current is greater than a preset current threshold; or the output voltage of the second communication socket is greater than the preset voltage threshold, and the output current is greater than the preset current threshold.

Here, the preset voltage threshold is a voltage allowable value of the contact resistance, and the preset current threshold is a current allowable value of the contact resistance.

That is to say, the output voltage of first communication socket is greater than and predetermines voltage threshold and output current is greater than and predetermines the electric current threshold, or, the output voltage of second communication socket is greater than and predetermines voltage threshold and output current is greater than and predetermines the electric current threshold, directly punctures rete resistance when first communication socket contacts with second communication socket, guarantees the normal interaction of information between host computer and the parasite aircraft.

In some embodiments, a first voltage and current amplification module is connected in series between the output end of the main machine and the first voltage and current detection module, and a second voltage and current amplification module is connected in series between the output end of the sub machine and the second voltage and current detection module; the first voltage and current amplification module is used for amplifying the output voltage and the output current of the host computer, so that the output voltage passing through the first communication socket is larger than a preset voltage threshold value, and the output current passing through the first communication socket is larger than a preset current threshold value; the second voltage and current amplification module is used for amplifying the output voltage and the output current of the submachine so as to enable the output voltage passing through the second communication jack to be larger than a preset voltage threshold value and enable the output current passing through the second communication jack to be larger than a preset current threshold value.

In practical application, because the output voltage and the output current of the host machine and the output voltage and the output current of the submachine are too low to break down the film resistor, the output end of the host machine is connected with the first voltage and current amplification module, the output end of the submachine is connected with the second voltage and current amplification module, so that the output voltage of the host machine is amplified to be greater than a preset voltage threshold value and the output current of the host machine is amplified to be greater than a preset current threshold value by using the first voltage and current amplification module, and the output voltage of the submachine is amplified to be greater than the preset voltage threshold value and the output current of the submachine is amplified to be greater than the preset current threshold value by using the second voltage and current amplification module.

Step 102: the sub machine responds to the first instruction to generate response information, and the control host machine receives the response information sent by the sub machine through the information transmission line.

In some embodiments, the communication mode of the information transmission line is a single-wire half-duplex communication mode.

It should be noted that, general information interaction includes 4 lines, namely, a VCC power line, an RXD receiving line, a TXD transmitting line and a GND ground line, and the more signal bits, the more the socket is affected by structural design and installation errors, and the possibility of alignment failure exists in the socket. In order to reduce the risk of alignment failure, the RXD receiving wire, the TXD transmitting wire and the GND ground wire share one wire, namely information interaction is adjusted to be 2 wires (comprising a power supply socket and a communication socket) from 4 wires, and therefore the risk of alignment failure is reduced. Wherein, power supply socket and communication socket can set up to the haplopore and aim at, also can set up to spring, magnetism to inhale the formula butt joint.

Specifically, the host machine and the slave machine are both arranged in a single-wire half-duplex communication mode, the single-wire half-duplex communication mode refers to simplex communication capable of switching directions, namely, the host machine sends information to the slave machine (corresponding to step 101) and the slave machine sends information to the host machine (corresponding to step 102) through the same information transmission line based on the single-wire half-duplex communication mode.

Exemplarily, the submachine is the oxygenerator, and when first instruction was the oxygenerator instruction, the host computer sent the oxygenerator instruction to the submachine, and when until the submachine response oxygenerator instruction, the control submachine was sent the response information that the information transmission line corresponds the oxygenerator instruction to the host computer, and when the host computer received this response information, stopped sending the oxygenerator instruction to the submachine. When the first instruction is a shutdown instruction, the host machine sends the shutdown instruction to the submachine, the submachine responds to the shutdown instruction and controls the submachine to send shutdown information to the host machine through the information transmission line, and when the host machine receives the shutdown information, the host machine stops supplying power to the submachine.

Here, the execution subject of steps 101 to 102 may be a processor of the information interaction apparatus.

In the embodiment, the situation that the information interaction fails because the voltages and currents of the output ends of the host machine and the sub machine are small and the contact resistance cannot be broken down is pointed out, and the corresponding voltage and current amplification modules are arranged on the host machine and the sub machine; in order to ensure that information interaction is correct, the corresponding voltage and current detection module is arranged on either the host machine or the submachine, and when the voltage and current detection module detects that the output voltage and the output current of the communication socket meet communication conditions, the correctness of the information interaction between the host machine and the submachine can be ensured. In view of the above, the present application provides a first voltage-current amplifying circuit for a first voltage-current amplifying module on the host machine, and a second voltage-current amplifying circuit for a second voltage-current amplifying module on the slave machine, and fig. 3 is a schematic structural diagram of the first voltage-current amplifying circuit and the second voltage-current amplifying circuit in the embodiment of the present application, where in fig. 3, a first voltage-current detecting module is installed on the host machine, or a second voltage-current detecting module is installed on the slave machine (schematic diagram is not given here).

As shown in fig. 3, taking the first output voltage of the host as 5V and the second output voltage of the slave as 5V, the first voltage-current amplifier and the second voltage-current amplifier amplify the voltage into 12V respectively, and amplify the current in the circuit, and the first voltage-current detection module detects that the amplified voltage 12V is greater than the preset voltage threshold at the point where the CN1 end and the CN2 end communicate with each other, and the amplified current is greater than the preset current threshold at the point where the CN1 end and the CN2 end communicate with each other, so that the film resistor can be directly broken through, and the normal interaction of information between the host and the slave is realized.

It should be noted that the first voltage-current amplification circuit and the second voltage-current amplification circuit shown in fig. 3 are only exemplary circuits, and any other circuits may be used as long as the above functions can be achieved.

Based on the above embodiment, the present application further provides an information interaction method, and fig. 4 is a second flow diagram of the information interaction method in the embodiment of the present application.

As shown in fig. 4, the information interaction method is applied to an air conditioner, the air conditioner comprises a host machine and a sub machine, the host machine comprises a first jack, and the sub machine comprises a second jack corresponding to the first jack; the information interaction method comprises the following steps:

step 401: when the host receives the second instruction, responding to the second instruction, and detecting whether the submachine is installed in place on the host;

here, the second instruction is a detection instruction. Illustratively, the host receives the detection instruction by clicking a detection key on a terminal Application (APP), clicking a detection key on a remote control board of the control host, or clicking a detection key on the host.

Here, after the host receives the detection instruction, in order to avoid the occurrence of an unsafe problem caused by operations such as the host directly supplying power to the slave when the slave is not installed in place, it is necessary to first detect whether the slave is installed in place on the host.

In some embodiments, the host further includes a first switch and a second switch, and the open-close state of the first switch represents whether the sub-machine is covered by an upper panel of the host; the opening and closing state of the second switch represents whether the sub machine is inserted into the main machine installation cavity or not; whether the detection parasite aircraft is installed in place on the host computer includes: detecting whether the first switch and the second switch are both in a closed state; if both are in a closed state, determining that the submachine is installed in place on the main machine; and if any one switch is in an open state, determining that the sub machine is not installed in place on the main machine.

That is to say, the panel switch state of the host machine covering the sub machine and the switch state of the second switch in the installation cavity of the sub machine are detected, if the panel switch is detected to be in the open state and the second switch is detected to be in the closed state, children may drive to pull out the sub machine due to curiosity, at the moment, the sub machine is in the charged state, sparks are easily generated when the sub machine is directly pulled out, and electric shock is possibly unsafe; if the second switch is detected to be in an open state, the sub machine is not inserted into the main machine mounting cavity no matter the panel switch is in a closed state or an open state at the moment; therefore, only when the panel switch and the second switch are both in a closed state, the sub-machine is installed in place on the main machine, and the unsafe problem does not exist.

For the setting of the first switch (for example, a panel switch), the lower expansion functional component in fig. 2 includes a panel and a chassis, and the panel switch is mounted on the chassis, and for example, the panel switch may be a magnetic switch or a push switch.

The positioning contact is a magnetic component which can be identified by a magnetic control switch (namely a second switch) or a mechanical component which can push a key switch (namely the second switch), and the magnetic control switch or the key switch which is matched with the positioning contact for use is arranged in an oxygen making device installation cavity on the host machine. Airflow interface includes the air inlet, oxygen gas vent and nitrogen gas vent, after oxygenerator packs into the air conditioner, oxygenerator's air inlet and the lower wind channel intercommunication of the lower extension functional unit of air conditioner, the back is opened to lower wind channel air inlet valve, the air reachs the oxygenerator air inlet through upper and lower wind channel, oxygenerator oxygen gas outlet and the air outlet intercommunication of expanding functional unit down, can arrange oxygen to indoorly from the air outlet, the nitrogen gas outlet pipeline that has still pre-buried on the lower extension functional unit, the nitrogen gas outlet pipeline extends to outdoors, the direct butt joint of pre-buried nitrogen gas outlet pipeline on oxygenerator packs into air conditioner back nitrogen gas outlet and the air conditioner, in order to discharge nitrogen gas outdoors.

Step 402: when the submachine is installed in place on the host computer, detecting whether the output voltage and the output current of any communication socket meet communication conditions when the first communication socket is connected with the second communication socket;

here, the first socket indicated above includes a first communication socket, and the second socket includes a second communication socket;

in some embodiments, the first socket further comprises a first power supply socket, and the second socket further comprises a second power supply socket; the first communication socket is connected with the first voltage and current detection module, and the second communication socket is connected with the second voltage and current detection module; after the submachine is determined to be installed in place on the main machine, the method further comprises the following steps: the control host computer supplies power to the submachine through a first power supply socket and a second power supply socket; the control host sends a first self-checking signal to the first voltage and current detection module, and the first voltage and current detection module is used for detecting whether the output voltage and the output current of the first communication socket meet communication conditions; or the submachine is controlled to send a second self-checking signal to the second voltage and current detection module, and the second voltage and current detection module is used for detecting whether the output voltage and the output current of the second communication socket meet the communication condition.

In some embodiments, a first voltage and current amplification module is connected in series between the output end of the host machine and the first voltage and current detection module, and a second voltage and current amplification module is connected in series between the output end of the sub machine and the second voltage and current detection module; the first voltage and current amplification module is used for amplifying the output voltage and the output current of the host computer, so that the output voltage passing through the first communication socket is larger than a preset voltage threshold value, and the output current passing through the first communication socket is larger than a preset current threshold value; the second voltage and current amplification module is used for amplifying the output voltage and the output current of the submachine so as to enable the output voltage passing through the second communication socket to be larger than a preset voltage threshold value and the output current passing through the second communication socket to be larger than a preset current threshold value.

Step 403: when the communication condition is met, the control host sends a first instruction to the submachine through an information transmission line consisting of the first communication socket and the second communication socket;

in practical application, when the first communication socket and the second communication socket meet communication conditions, the control host computer sends a first instruction to the submachine according to a preset time period through the information transmission line, and the host computer stops sending the first instruction to the submachine until the submachine receives and responds to an oxygen generation instruction.

Step 404: the sub machine responds to the first instruction to generate response information, and the control host machine receives the response information sent by the sub machine through the information transmission line.

Exemplarily, the submachine is the oxygenerator, and when first instruction was the oxygenerator instruction, the submachine response oxygenerator instruction, and the response information that control submachine will make the oxygenerator instruction and send to the host computer through information transmission line, and the host computer stops sending the oxygenerator instruction to the submachine.

Illustratively, if the response information is fault information, the host stops supplying power to the submachine and sends alarm information to prompt a user that the submachine has a fault.

In some embodiments, the method further comprises: when the host receives the shutdown instruction or detects that the first switch is in an open state, the host is controlled to send the shutdown instruction to the submachine through the information transmission line; the submachine responds to the stop instruction and returns corresponding stop information to the mainframe through the information transmission line; and the control host controls the submachine to be in a non-working state based on the shutdown information.

Here, use the parasite aircraft as oxygenerator for the example, the host computer receives the instruction of shutting down, probably because the host computer sends oxygen concentration inquiry instruction to the parasite aircraft through information transmission line, the parasite aircraft returns oxygen concentration in with current air to the host computer through information transmission line, the host computer detects oxygen concentration in the air and reaches the threshold value, send alarm information with the suggestion user click on terminal APP make oxygen system shut down the button, click the system oxygen on the remote control board of control host computer and shut down the button or click the system oxygen on the host computer and shut down the button, so that the host computer receives the instruction of shutting down. The host sends the received stopping instruction to the submachine, and after the submachine responds to the stopping instruction to stop oxygen generation, the host stops supplying power to the submachine so that the submachine is in an out-of-operation state.

Or, when detecting that the panel switch (i.e. the first switch) is in the open state, the problem of insecurity exists, so the host computer also needs to be controlled to send the shutdown instruction to the submachine through the information transmission line, and after the submachine responds to the shutdown instruction to stop oxygen generation, the host computer stops supplying power to the submachine so as to enable the submachine to be in the non-working state. Compared with the mode that the host directly stops supplying power to the submachine after receiving the stop command, the mode of controlling the submachine to be in the non-operating state can prolong the service life of the submachine.

Based on the above embodiments, the main machine of the embodiment of the present application takes an air conditioner, and the sub-machine takes an oxygen generator as an example, and a control structure diagram of the oxygen generator is provided, and fig. 6 is a schematic diagram of the control structure of the oxygen generator in the embodiment of the present application.

As shown in fig. 6, when the air conditioner 61 receives the detection instruction, the control detection component 614 detects whether the first switch and the second switch indicated in the above embodiment are both in the closed state, and when both are in the closed state, the air conditioner control board 615 receives the related instruction information, and then controls the air inlet/outlet valve component 618 to open and close, and controls the power module 610 of the high-power switch to turn on or off through the relay driving circuit 616, and after the power module 610 of the high-power switch turns on or off, the air conditioner 61 cannot supply power to the oxygen generation device 60 through the first power supply socket 612 in the oxygen generation load interface board 611 and the second power supply socket 606 in the oxygen generation input interface 605, that is, the oxygen generation device 60 turns on or off accordingly. After the oxygen generating device 60 is powered on, the oxygen generating device 60 waits for receiving an oxygen generating starting instruction sent by the air conditioner 61 through the first communication socket 613 and the second communication socket 607, and after the oxygen generating starting instruction is received, the oxygen generating device 60 controls the oxygen generating core component 601 to work and starts oxygen generation; after receiving the fault or oxygen concentration query information, the oxygen generator 60 returns the information pre-queried by the air conditioner 61; after receiving the shutdown instruction, the oxygen generation device 60 controls the oxygen generation core component 601 to execute the shutdown operation and then sends shutdown information to the air conditioner 61, and the air conditioner 61 controls the oxygen generation device 60 to power off and closes the air inlet valve assembly 618. The first voltage and current amplifying circuit 617 pre-adjusts the output voltage of the first communication jack 613, and the second voltage and current amplifying circuit 604 pre-adjusts the output voltage of the second communication jack 607, so that the film layer resistance between the communication contacts can be directly broken down after the first communication jack 613 and the second communication jack 607 are in contact with each other, thereby realizing information interaction between the oxygen generating device 60 and the air conditioner 61. Here, the voltage and current detection module is not illustrated in fig. 6, and specifically, the first voltage and current detection module may be connected in series between the first communication jack 613 and the first voltage and current amplification circuit 617, or the second voltage and current detection module may be connected in series between the second communication jack 607 and the second voltage and current amplification circuit 604.
