[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0025] In the related art, the current photoelectric switch detection solutions on the market all use a single-channel photoelectric switch detection circuit for detection.

[0026] There are the following problems: to detect the signals of two photoelectric switches, two single-channel photoelectric switch detection circuits are required for detection, and two chip I / O ports are also required. This solution leads to many peripheral circuit components, occupies more chip I / O ports and resources, and is relatively expensive.

[0027] In response to the above problems and taking into account the problems existing in the prior art, the applicant has proposed a detection method and electronic device according to an embodiment of the present application, which are applied to a photoelectric switch detection circuit. The photoelectric switch detection circuit includes an MCU and a photoelectric switch. The I / O port of the MCU provides a power cutoff for the photoelectric switch. The AD sampling port of the MCU is used to detect the voltage value at both ends of the photoelectric switch. The photoelectric switch includes a first photoelectric switch and a second photoelectric switch. The detection method includes: obtaining the voltage value at both ends of the photoelectric switch, and determining the working state of the grating of the photoelectric switch based on the voltage value. This achieves circuit simplification without reducing functions, reduces components, saves chip I / O ports, reduces chip resource requirements, and uses one I / O to detect the states of two photoelectric switches. An I / O port of the MCU is used to provide a power cutoff function for the photoelectric switch detection circuit. The detection method is described in detail in subsequent embodiments.

[0028] In this embodiment, the detection method can be applied to electronic devices, where the electronic device, taking a complete machine as an example, can be a complete machine for heating, cooling and air production, and can have functions such as folding, etc. This application does not limit it.

[0029] The detection method involved in the embodiment of the present application can be applied to Figure 4 The electronic device 200 shown includes the above-mentioned photoelectric switch detection circuit, a memory 202 and a processor 204.

[0030] The following will describe various embodiments of the present application in detail with reference to the accompanying drawings.

[0031] See also Figure 1 , Figure 1 A flow chart of a detection method provided in an embodiment of the present application is applied to a photoelectric switch detection circuit, the photoelectric switch detection circuit includes an MCU and a photoelectric switch, the I / O port of the MCU provides power disconnection for the photoelectric switch, the AD sampling port of the MCU is used to detect the voltage value at both ends of the photoelectric switch, the photoelectric switch includes a first photoelectric switch and a second photoelectric switch, and the method may include steps S110 to S120.

[0032] See also Figure 2 ,exist Figure 2In the photoelectric switch detection circuit shown, by designing and combining two photoelectric switches with an MCU I / O port and a resistor, different resistance values ​​can be set in the circuit to achieve load control, that is, the various operating states of the photoelectric switch's grating can be controlled. The detection method may include steps S110 to S120.

[0033] Step S110: obtaining the voltage value across the photoelectric switch.

[0034] In the embodiment of the present application, the voltage value across the photoelectric switch is obtained through an I / O port.

[0035] Step S120: determining the working state of the grating of the photoelectric switch based on the voltage value.

[0036] In the embodiment of the present application, the working state of the grating of the photoelectric switch is determined based on the voltage value obtained from the AD sampling port of the MCU, thereby judging the state of the entire machine by detecting the voltage value at both ends of the photoelectric switch, reducing the use of components and reducing development costs.

[0037] In an embodiment of the present application, an I / O is used as an AD sampling port to compare the detected voltage values ​​to determine the status of the two gratings. This achieves circuit simplification without reducing functions, reduces components, saves chip I / O ports, and reduces chip resource requirements.

[0038] In some embodiments, the detection method further includes step S130: determining the placement state of the whole machine based on the voltage value, wherein the whole machine includes: a foldable whole machine, and the placement states include: the whole machine folded and closed, the whole machine fully unfolded, and the whole machine unfolded on one side.

[0039] In the embodiments of this application, Figure 3 As shown, the appearance of the whole machine can be foldable, and it can be set to four placement states: the whole machine is closed, one side is open, the other side is open, and the whole machine is fully unfolded. It can be controlled by setting a relay to turn on different loads through different modes, and the voltage value is detected through the AD port. The placement state of the whole machine can be determined by the voltage value. Knowing the state of the whole machine, the state and working mode of the fan can be more effectively controlled.

[0040] In some embodiments, the entire machine includes operating modes with different gears.

[0041] It should be noted that the whole machine has multiple modes (low-range, mid-range, high-range), and the corresponding multiple gears and modes can be set according to user needs.

[0042] See also Figure 4 The workflow diagram of a detection method is as follows:

[0043] In some embodiments, the working mode includes: a high-end working mode, and step S120 may include: steps S121 to S123.

[0044] Step S121: judging whether the whole machine belongs to the high-end working mode based on the voltage value.

[0045] In an embodiment of the present application, the voltage value can be obtained according to the actual detection situation to obtain the current working mode of the whole machine, that is, it can be determined whether the whole machine belongs to the high-end working mode, where the high-end working mode indicates high energy consumption, power, etc.

[0046] Step S122: When it is determined that the entire machine is in the high-end working mode, power is supplied to the grating of the photoelectric switch.

[0047] Step S123: When it is determined that the entire machine does not belong to the high-end working mode, the power supply to the grating of the photoelectric switch is stopped.

[0048] On the one hand, when the gear is turned on to low or medium or in standby mode, the power supply to the grating is stopped and the I / O controlling the power supply to the grating is at a low level. On the other hand, when the gear is turned on to high, the power supply to the grating is turned on and the I / O controlling the power supply to the grating is at a high level.

[0049] In the embodiment of the present application, the power supply to the grating is adjusted and controlled by determining whether the entire machine is initially operating at a high speed.

[0050] In some embodiments, the first photoelectric switch is provided with a first grating, and the second photoelectric switch is provided with a second grating, and step S120 may include: steps S124 to S125.

[0051] Step S124: Determine the voltage value.

[0052] In the embodiment of the present application, the voltage value can be detected through the AD port to determine whether the voltage value meets the preset conditions.

[0053] Step S125: When it is determined that the voltage value is 0, it is determined that the first grating and the second grating are disconnected at the same time.

[0054] In some embodiments, when it is determined that the voltage value is not 0, step S120 may include: steps S126 to S128.

[0055] Step S126: Determine whether the voltage value is greater than a first threshold.

[0056] Step S127: when it is determined that the voltage value is greater than the first threshold, it is determined that the first grating and the second grating are closed at the same time.

[0057] Step S128: When it is determined that the voltage value is less than or equal to the first threshold, determine that the first grating is disconnected and the second grating is closed, or the first grating is closed and the second grating is disconnected.

[0058] It should be noted that the first threshold may also be set to a corresponding threshold range, which is determined according to actual usage.

[0059] In the embodiment of the present application, when the open gear is low or medium or in standby mode, the power supply to the grating is stopped and the I / O controlling the grating power supply is low. When the open gear is high, the power supply to the grating is turned on and the I / O controlling the grating power supply is high. At this time, the grating can have four states: two closed at the same time, two opened at the same time, the first opened and the second closed, and the second opened and the first closed.

[0060] For example, by designing different resistance values ​​on the grating circuit, the four voltage values ​​of the voltage across the photoelectric switch are detected using the AD detection port, which are 0V, aV, bV, and cV respectively. When the voltage is equal to 0, it is in two simultaneously disconnected states; when the voltage is greater than av and less than b, it is in the first disconnected state and the second closed state; when the voltage is greater than b and less than c, it is in the first closed state and the second disconnected state; when the voltage is greater than c, it is in two closed states.

[0061] In some embodiments, step S130 may further include: step S131 to step S132.

[0062] Step S131: Determine the voltage value

[0063] Step S132: when it is determined that the voltage value is 0, the placement state of the whole machine is determined to be that the whole machine is fully unfolded.

[0064] In some embodiments, when it is determined that the voltage value is not 0, step S130 may further include: steps S132 to S134.

[0065] Step S132: Determine whether the voltage value is greater than a first threshold.

[0066] Step S133: when it is determined that the voltage value is greater than the first threshold, determining that the placement state of the entire device is that one side of the entire device is unfolded.

[0067] Step S134: when it is determined that the voltage value is less than or equal to the first threshold, determining that the placement state of the entire device is the entire device is folded and closed.

[0068] In the embodiment of the present application, the four placement states of the above-mentioned whole machine are: the whole machine is closed, one side is open, the other side is open, and the whole machine is fully extended. The voltage value is detected through the AD port, and the voltage value is used to determine the state of the grating and the placement state of the whole machine. Knowing the state of the whole machine can more effectively control the state and operation mode of the fan. In order not to affect the service life of the grating, the traditional method is to complete this working process through two I / O ports and two photoelectric switches. Turning on the corresponding load based on the state of the whole machine can more effectively complete the state detection and reduce the probability of state errors caused by component failure.

[0069] In some embodiments, the detection method may further include steps S140 to S180.

[0070] Step S140: Determine the voltage value.

[0071] Step S150: when it is determined that the voltage value is 0, all loads in the high-end working mode are turned on.

[0072] In an embodiment of the present application, the operation of the entire machine can be set by turning on all loads in high-end working mode when it is confirmed that the entire machine is in a fully expanded state or the first grating and the second grating are both disconnected at the same time.

[0073] Step S160: When it is determined that the voltage value is not 0, determine whether the voltage value is greater than a first threshold.

[0074] Step S170: when it is determined that the voltage value is greater than the first threshold, turning on a load in the high-end working mode.

[0075] In the embodiment of the present application, when it is confirmed that the whole machine is in a folded state or the first grating and the second grating are closed at the same time, a load in the high-end working mode is turned on to adapt to the operating conditions of the whole machine.

[0076] Step S180: when it is determined that the voltage value is less than or equal to the first threshold, starting the duty cycle operation of the high-end operation mode.

[0077] In the embodiment of the present application, the high-end load-on duty cycle can be used when it is confirmed that the entire machine is in a semi-folded state or when the first grating and the second grating are both opened and closed.

[0078] For example, Figure 3 As shown, the load conditions of different modes can be determined by adjusting the working conditions of the relays in the whole machine and the placement of the whole machine.
