Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an implementation of a device pairing method according to a first embodiment of the present disclosure. The method is applied to control equipment and a plurality of controlled equipment, wherein an infrared light source is arranged on the control equipment, and an infrared sensing unit is arranged on the controlled equipment. As shown in fig. 1, the method mainly comprises the following steps:
101. each controlled device receives infrared light emitted by the control device through the infrared light source through the infrared sensing unit, and obtains the infrared light intensity value of the received infrared light.
Specifically, the internet of things device comprises a control device and a controlled device, the control device is controlled by a user, the control device sends a control instruction to the controlled device, and the controlled device responds to the action of the user after receiving the control instruction. Before sending a control instruction to a controlled device, the control device needs to perform pairing operation with the controlled device. In the embodiment of the invention, the control device firstly emits infrared light, and each controlled device measures the intensity value of the received infrared light by using the respective infrared sensing unit and acquires the infrared light intensity value of the received infrared light.
102. And each controlled device receives the light intensity threshold value sent by the control device, generates a threshold lifting request and a new light intensity threshold value according to the infrared light intensity value and the light intensity threshold value, and sends the threshold lifting request and the new light intensity threshold value to the control device.
Specifically, in each pairing operation, the control device is to select the controlled device pointed by the control device to perform pairing, and the infrared light intensity value of the controlled device pointed by the control device is larger. Therefore, in order to determine the directed controlled device, the control device sets a light intensity threshold and sends the light intensity threshold to the controlled devices, each controlled device generates a threshold lifting request and obtains a new light intensity threshold according to the relation between the infrared light intensity value and the light intensity threshold, and sends the threshold lifting request and the new light intensity threshold to the control device, so that the control device adjusts the light intensity threshold, and the controlled device with the maximum received infrared light intensity value is indirectly determined. Optionally, the light intensity threshold sent by the control device for the first time is smaller and may be 0.
103. And the control equipment determines target controlled equipment according to the lifting threshold value requests and the infrared light intensity values sent by the controlled equipment and matches the target controlled equipment.
Specifically, the control device continuously adjusts the light intensity threshold according to the threshold lifting request and the new light intensity threshold, so as to indirectly determine the controlled device with the maximum received infrared light intensity, which indicates the direction of the controlled device closest to the control device, and the controlled device is the target controlled device, so that the target controlled device and the control device are connected in a pairing manner, and the target controlled device subsequently receives and executes the instruction of the control device.

And the control equipment sends the light intensity threshold value to the controlled equipment, so that the controlled equipment generates a new light intensity threshold value according to the light intensity threshold value and sends the new light intensity threshold value to the control equipment, the infrared light intensity value received by the controlled equipment is indirectly compared, the target controlled equipment is further determined, and data is not shared among the controlled equipment for size comparison, and the network overhead is reduced.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an implementation of a device pairing method in a second embodiment provided by the present invention. As shown in fig. 2, the method mainly includes the following steps:
201. each controlled device receives infrared light emitted by the control device through the infrared light source through the infrared sensing unit, and obtains the infrared light intensity value of the received infrared light.
Specifically, the internet of things device comprises a control device and a controlled device, the control device is controlled by a user, the control device sends a control instruction to the controlled device, and the controlled device responds to the action of the user after receiving the control instruction. Before sending a control instruction to a controlled device, the control device needs to perform pairing operation with the controlled device. In the embodiment of the invention, the control device firstly emits infrared light, each controlled device receives the infrared light by using the respective infrared sensing unit, and the infrared light intensity value of the received infrared light is obtained.
The communication protocol between the control device and the controlled devices can be ZigBee. The ZigBee technology is a two-way communication technology, has the characteristics of short distance, low complexity, low power consumption, low speed and low cost, and can be applied to data transmission between control equipment and controlled equipment.
202. And each controlled device receives the light intensity threshold value sent by the control device and calculates the difference between the infrared light intensity value and the light intensity threshold value.
Specifically, each controlled device receives the light intensity threshold sent by the control device, and then compares the infrared light intensity value with the light intensity threshold. If the infrared light intensity value of the infrared light received by the controlled device is not less than the light intensity threshold value, that is, the difference between the infrared light intensity value of the controlled device and the light intensity threshold value is not less than zero, the controlled device can be considered to be in the range of the infrared light emitted by the control device by using the infrared light source. If the infrared light intensity value of the controlled device is smaller than the light intensity threshold value, that is, the difference between the infrared light intensity value of the controlled device and the light intensity threshold value is smaller than zero, the controlled device is considered not to be in the range of the infrared light emitted by the control device by using the infrared light source. In practical applications, after the controlled device receives the light intensity threshold, the state of the controlled device can be marked as "in-range" or "out of range" according to the relationship between the light intensity threshold and the infrared light intensity value.
203. And if the infrared light intensity value acquired by each controlled device through the infrared sensing unit changes, each controlled device updates the infrared light intensity value.
Specifically, if the pointing direction of the control device changes, the emission direction of the infrared light source of the control device changes, the positional relationship between each controlled device and the infrared light source of the control device changes, the infrared light intensity of each controlled device changes, and the infrared light intensity value obtained by the infrared sensing unit changes, so that the infrared light intensity values of the controlled devices are updated.
204. If the difference between the infrared light intensity value and the light intensity threshold value is larger than a preset difference value, the controlled equipment generates a threshold lifting request and a new light intensity threshold value, and sends the threshold lifting request and the new light intensity threshold value to the control equipment.
Specifically, the controlled device is preset with a preset difference value, and the difference between the infrared light intensity value and the light intensity threshold value is compared with the preset difference value, so that a new light intensity threshold value is generated, and the number of the controlled devices in the range of the infrared light emitted by the control device is gradually reduced. And if the difference between the infrared light intensity value of the controlled equipment and the light intensity threshold is larger than the preset difference, the controlled equipment sends a threshold lifting request and a new light intensity threshold to the control equipment. And if the difference between the infrared light intensity value of the controlled equipment and the light intensity threshold value is not greater than the preset difference value, the controlled equipment does not send a threshold value lifting request to the control equipment. It is understood that the preset difference is greater than zero, and the preset difference can be determined according to the user's needs. In practical applications, a new light intensity threshold may be piggybacked on the raise threshold request.
The new light intensity threshold is smaller than the infrared light intensity value, and the new light intensity threshold is equal to the difference between the infrared light intensity value and the preset difference value.
205. The control device selectively receives the lifting threshold request and the new light intensity threshold value sent by one of the controlled devices, and updates the light intensity threshold value according to the lifting threshold request and the new light intensity threshold value of the one of the controlled devices.
Specifically, the plurality of controlled devices send the lifting threshold request and the new light intensity threshold value to the control device, but the control device selects to receive the lifting threshold request and the new light intensity threshold value of one of the controlled devices, and updates the light intensity threshold value according to the new light intensity threshold value, and the updated light intensity threshold value is equal to the new light intensity threshold value. In practical applications, the user may customize the algorithm selection to receive the raise threshold request and the new light intensity threshold.
Wherein the updated light intensity threshold is less than the infrared light intensity value of the one of the controlled devices, and the updated light intensity threshold is equal to a difference between the infrared light intensity value of the one of the controlled devices and the preset difference.
206. And the control equipment sends the updated light intensity threshold to a plurality of controlled equipment until the control equipment does not receive the threshold lifting request any more, and finally the controlled equipment sending the threshold lifting request is target controlled equipment which is paired with the target controlled equipment.
Specifically, after the control device updates the light intensity threshold, the updated light intensity threshold is sent to the controlled devices, and step 202 is executed, so that the light intensity threshold is raised for multiple times, the number of the controlled devices within the range of the infrared light emitted by the infrared light source of the control device is reduced until the control device does not receive the raising threshold request any more, after the controlled device finally sends the sending request of the raising threshold request, no more controlled device sends the raising threshold request, and the controlled device finally sending the raising threshold request is the controlled device with the maximum infrared light intensity value, and then the control device is paired with the controlled device finally sending the raising threshold request.
In practical application, when the controlled device is in the range of the infrared light emitted by the infrared light source of the control device, the indicator light of the controlled device flashes red light, so that the user can observe the flashing condition of the indicator light of the controlled device, judge the number of the controlled devices currently in the range of the infrared light emitted by the infrared light source of the control device, and when the control device does not receive the threshold increasing request any more, the controlled device which finally sends the threshold increasing request flashes red light, so that the user inputs an active query instruction, the control device sends a request pairing instruction to the controlled device in response to the active query instruction, the controlled device returns the pairing instruction to the control device, and the control device and the controlled device are paired.
Optionally, if the infrared light intensity value of the controlled device is greater than the light intensity threshold value but the difference between the infrared light intensity value and the light intensity threshold value is not greater than the preset difference value, that is, the condition of sending the request for raising the threshold value is not met, but the controlled device is also within the range of the infrared light emitted by the infrared light source of the control device, the user inputs an active query instruction, the control device responds to the active query instruction, sends a request pairing instruction to the controlled device, the controlled device returns a pairing instruction to the control device, and the control device and the controlled device perform pairing.
207. And if the difference between the light intensity threshold and the infrared light intensity value before the controlled equipment is updated is smaller than the preset difference, and the difference between the light intensity threshold and the infrared light intensity value after the controlled equipment is updated is not smaller than the preset difference, the controlled equipment generates a falling threshold request and a new light intensity threshold and sends the falling threshold request and the new light intensity threshold to the control equipment.
Specifically, if the difference between the light intensity threshold and the infrared light intensity value before the controlled device is updated is smaller than the preset difference, it indicates that the controlled device is within the range of the infrared light emitted by the control device before the controlled device is updated. If the difference between the light intensity threshold and the updated infrared light intensity value of the controlled device is not less than the preset difference, it indicates that the controlled device is not in the range of the infrared light emitted by the control device after the direction of the control device is changed. That is, when the orientation of the control device is changed, the controlled device changes from being in the range of the infrared light of the control device to not being in the range of the infrared light emitted by the control device, and the controlled device generates a drop threshold request and a new light intensity threshold and transmits them to the control device.
The new light intensity threshold is greater than the updated infrared light intensity value, and the new light intensity threshold is equal to the sum of the updated infrared light intensity value and the preset difference.
208. The control device selectively receives the drop threshold request and the new light intensity threshold sent by one of the controlled devices, and updates the light intensity threshold according to the drop threshold request and the new light intensity threshold of the one of the controlled devices.
Specifically, the plurality of controlled devices send the drop threshold request and the new light intensity threshold to the control device, but the control device selects to receive the drop threshold request and the new light intensity threshold of one of the controlled devices, and updates the light intensity threshold according to the drop threshold request and the new light intensity threshold, and the updated light intensity threshold is equal to the new light intensity threshold. In practical applications, the user may customize the algorithm selection to receive the drop threshold request and the new light intensity threshold.
Exemplarily, as shown in fig. 3, it is a schematic diagram of a first application of the device pairing method in the second embodiment provided by the present invention. The control equipment sends infrared light to the controlled equipment, and each controlled equipment acquires an infrared light intensity value by using an infrared sensing unit of the controlled equipment. The number of control devices is 1, and the number of controlled devices is 4. The 5 steps of the light intensity threshold raising process are illustrated from left to right, respectively. The abscissa in the sub-diagram represents the serial number of the controlled device and the ordinate represents the relative light intensity of 0-100% for ease of illustration. The horizontal lines in each sub-graph represent the light intensity threshold.
In step 1, the light intensity threshold value initially emitted by the control device is at a lower level, and the infrared light intensity values of the controlled devices 1 to 4 are all greater than the light intensity threshold value, so that the controlled devices 1 to 4 are all within the range of the infrared light emitted by the control device. And if the difference between the infrared light intensity value of the controlled equipment 1-4 and the light intensity threshold is greater than the preset difference, the controlled equipment 1-4 generates a threshold lifting request and a new light intensity threshold and sends the threshold lifting request and the new light intensity threshold to the control equipment. Wherein the new light intensity threshold of each controlled device is less than the infrared light intensity value and is equal to the difference between the infrared light intensity value of each controlled device and a preset difference value.
In step 2, if the control device selects the received controlled device as the controlled device 1, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 1, the control device uses the new light intensity threshold value of the controlled device 1 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 1, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 1 and a preset difference value, and the updated light intensity threshold value is sent to each controlled device. The controlled devices 1-4 are all in the range of the infrared light transmitted by the control device at this time. However, the condition for sending the threshold raising request is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold is greater than the preset difference, but the difference between the infrared light intensity value of the controlled device 1 and the light intensity threshold is not greater than the preset difference, so that the controlled device 1 does not send the threshold raising request any more, and the controlled devices 2 to 4 send new threshold raising requests.
Correspondingly, in step 3, if the controlled device selected by the control device to be received is the controlled device 4, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 4, the control device uses the new light intensity threshold value of the controlled device 4 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 4, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 4 and the preset difference value, and the updated light intensity threshold value is sent to each controlled device. The controlled devices 2-4 are all in the range of the infrared light transmitted by the control device at this time. However, the condition for sending the threshold raising request is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold is greater than the preset difference, but the difference between the infrared light intensity value of the controlled device 4 and the light intensity threshold is not greater than the preset difference, so that the controlled device 4 does not send the threshold raising request any more, and the controlled devices 2 and 3 send new threshold raising requests.
Correspondingly, in step 4, if the control device selects the received controlled device as the controlled device 2, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 2, the control device uses the new light intensity threshold value of the controlled device 2 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 2, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 2 and the preset difference value, and the updated light intensity threshold value is sent to each controlled device. Both the controlled devices 2 and 3 are now in the range of the infrared light transmitted by the control device. However, the condition for sending the threshold raising request is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold is greater than the preset difference, but the difference between the infrared light intensity value of the controlled device 2 and the light intensity threshold is not greater than the preset difference, so that the controlled device 2 does not send the threshold raising request any more, and the controlled device 3 sends a new threshold raising request.
Correspondingly, in step 5, if the control device selects the received controlled device as the controlled device 3, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 3, the control device takes the new light intensity threshold value of the controlled device 3 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 3, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 3 and the preset difference value, and the updated light intensity threshold value is sent to each controlled device. The controlled device 3 is now within the range of the infrared light transmitted by the control device. However, the condition for sending the request for raising the threshold value is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold value is greater than the preset difference, but the difference between the infrared light intensity value of the controlled device 3 and the light intensity threshold value is not greater than the preset difference, so that the controlled device 3 does not send the request for raising the threshold value any more.
In the actual pairing process, steps 1-5 can be performed sequentially. After step 1, since the control device selects the received controlled device to be random, steps 2-5 can be performed by skipping part of the steps to accommodate the situation where part of the request for raising the threshold is lost without affecting the process of raising the light intensity threshold upward.
If the direction of the control device changes, a mechanism for updating the light intensity threshold downwards needs to be executed when the infrared light intensity value received by each controlled device changes. Fig. 4 is a schematic diagram of a second application of the device pairing method in the second embodiment of the present invention. Step 1 in fig. 4 follows step 5 in fig. 3, the same as step 5 in fig. 3.
In step 2, the pointing direction of the control device is changed, the updated infrared light intensity value of the controlled device 3 is smaller than the light intensity threshold, and at this time, none of the controlled devices 1 to 4 is in the range of the infrared light sent by the control device. And the controlled device 3 is in the range of the infrared light sent by the control device before the direction of the control device is changed, and is not in the range of the infrared light sent by the control device after the direction of the control device is changed, so the controlled device 3 generates a drop threshold request and a new light intensity threshold and sends the requests and the new light intensity threshold to the control device. Wherein the new light intensity threshold of the controlled device 3 is greater than the infrared light intensity value and is equal to the sum of the infrared light intensity of the controlled device 3 and a preset difference.
In step 3, if the control device selects the received controlled device as the controlled device 3, the control device receives the drop threshold request and the new light intensity threshold of the controlled device 3, the control device uses the new light intensity threshold of the controlled device 3 as an updated light intensity threshold, the updated light intensity threshold is raised to be slightly higher than the infrared light intensity value of the controlled device 3, and the updated light intensity threshold is equal to the sum of the infrared light intensity value of the controlled device 3 and a preset difference, and the updated light intensity threshold is sent to each controlled device. After the light intensity threshold value is updated, the controlled devices 1 and 3 are not in the range of the infrared light transmitted by the control device, the controlled devices 2 and 4 are in the range of the infrared light transmitted by the control device, and the difference between the infrared light intensity value of the controlled devices 2 and 4 and the light intensity threshold value is greater than a preset difference value, so that the controlled devices 2 and 4 transmit a threshold value raising request.
Correspondingly, in step 4, if the controlled device selected by the control device to be received is the controlled device 4, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 4, the control device uses the new light intensity threshold value of the controlled device 4 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 4, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 4 and the preset difference value, and the updated light intensity threshold value is sent to each controlled device. The controlled devices 2 and 4 are now in the range of the infrared light transmitted by the control device. However, the condition for sending the threshold raising request is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold is greater than the preset difference, but the difference between the infrared light intensity value of the controlled device 4 and the light intensity threshold is not greater than the preset difference, so that the controlled device 4 does not send the threshold raising request any more, and the controlled device 2 sends a new threshold raising request.
Correspondingly, in step 5, if the control device selects the received controlled device as the controlled device 2, the control device receives the request for the lifting threshold value and the new light intensity threshold value of the controlled device 2, the control device uses the new light intensity threshold value of the controlled device 2 as an updated light intensity threshold value, the updated light intensity threshold value is lifted to be slightly lower than the infrared light intensity value of the controlled device 2, the updated light intensity threshold value is equal to the difference between the infrared light intensity value of the controlled device 2 and the preset difference value, and the updated light intensity threshold value is sent to each controlled device. The controlled devices 2 are all in the range of the infrared light transmitted by the control device at this time. However, the condition for sending the request for raising the threshold value is that the difference between the infrared light intensity value of the controlled device and the light intensity threshold value is greater than the preset difference value, but the difference between the infrared light intensity value of the controlled device 2 and the light intensity threshold value is not greater than the preset difference value at this time, so the controlled device 2 does not send the request for raising the threshold value any more.
In the actual pairing process, steps 1-5 in fig. 3 and steps 2-5 in fig. 4 may be performed sequentially. After steps 1-3 are performed in fig. 4, since the controlled device selected by the control device for reception can be randomly selected, steps 4-5 can be performed randomly to adapt to the situation that part of the request for raising the threshold is lost without affecting the process of raising the light intensity threshold upwards after updating the light intensity threshold downwards.
In the embodiment of the invention, the control equipment emits infrared light, the controlled equipment receives the infrared light and acquires the infrared light intensity value, and the matched target controlled equipment is determined by the infrared light without using third-party electronic equipment, so that the equipment matching convenience is improved. And the control equipment sends the light intensity threshold value to the controlled equipment, so that the controlled equipment generates a new light intensity threshold value according to the light intensity threshold value and sends the new light intensity threshold value to the control equipment, the infrared light intensity value received by the controlled equipment is indirectly compared, the target controlled equipment is further determined, and data is not shared among the controlled equipment for size comparison, and the network overhead is reduced. In addition, the directional change of the control equipment is considered, and the flexibility of equipment pairing is improved.
