Description
Technical Field
The present invention relates to the field of wireless control technologies, and in particular, to a wireless device communication method and a wireless device control system.
Background
In a network environment, each intelligent device often needs to feed back its operating state to the gateway, but if each intelligent device feeds back its state to the gateway at the same time at the moment of starting or receiving the gateway "feedback state" command, it may cause mutual interference between state feedback signals and cause signal blockage, wherein some intelligent devices with unsuccessful signal transmission will repeatedly transmit until the signal transmission succeeds, further blocking transmission channels, and seriously deteriorating the regional network environment.
In order to solve the problem, in the prior art, a delay random number t is often set for a signal transmitted by the intelligent device as the time for delaying transmission, that is, after a feedback state command is received, a state feedback signal is transmitted after t seconds. In the prior art, t is often generated by setting a certain random number generation rule for the smart device, generally called "pseudo random number", and for this way, if a plurality of identical smart devices exist in the same network environment, because the rules for generating random numbers are the same, there still exists a situation that signals interfere with each other.
In the prior art, another way for generating the random number by the intelligent device is to generate the random number by attaching a random number generation function to a single chip microcomputer in the intelligent device, because the random number is taken by the single chip microcomputer, the randomness of the random number is larger, generally called as a true random number, and this way can greatly reduce the mutual interference of signals in the same network environment, but the single chip microcomputer with the function is often expensive, and the production cost of the intelligent device is greatly improved.
Therefore, a method for generating a true random number by using intelligent devices is needed, which can maintain low production cost of the intelligent devices and enable the intelligent devices to generate the true random number, so that the intelligent devices can smoothly transmit signals without mutual interference, and the signal blockage situation is effectively avoided.

Referring to fig. 1 to 7 of the drawings accompanying the present specification, a wireless device communication method and a wireless device control system according to a first preferred embodiment of the present invention are explained in the following description. The wireless device control system is adapted to one or more wireless devices through which the plurality of wireless devices are connected and controlled. It should be noted that the wireless device control system of the present invention is used for wireless control or remote control of smart home devices. Therefore, the wireless device can be a lamp, a motor, and other smart home systems.
The wireless device control system comprises a switch, an actuator and a gateway, wherein the actuator is arranged on the wireless device, and the actuator controls the working state of the wireless device. It is worth mentioning that in this preferred embodiment of the invention, the wireless device control system is adapted to control one or more wireless devices. Correspondingly, each wireless device is uniquely corresponding to one actuator, wherein each actuator can be respectively paired with the switch, and the switch sends a control command corresponding to the current wireless device to the actuator. The actuator controls the working state of the wireless equipment based on the control command sent by the switch. The gateway and the actuators may be connected in a paired manner, where the gateway may transmit a control command to each of the actuators, and the actuators control the operating states of the corresponding wireless devices based on the control command transmitted by the gateway. The state feedback information of the actuator is fed back to the gateway. The gateway and the switch can also be connected in a matching mode, the switch sends control information to the gateway, and the gateway transmits the control information to each actuator corresponding to the wireless equipment.
It is worth mentioning that the gateway can be connected to the internet, so that the gateway can be connected with a mobile phone, a computer and other electronic equipment with network connection in a communication way through the internet, and the gateway sends the state feedback information of each actuator to mobile-end electronic equipment such as the mobile phone through the internet; the mobile terminal electronic equipment sends the corresponding control information to the gateway through the Internet, and then the gateway sends the corresponding control information to each actuator of the corresponding wireless equipment, so that the wireless equipment is remotely and wirelessly controlled.
The method for realizing the remote control of the wireless equipment needs the following steps that the switch is connected with the actuator in a matching way; the gateway is connected with the actuator; and the connection of the switch to the gateway. In detail, in a control system of the wireless device, a gateway is used as a bridge to be communicated with the internet, so that collection and other intelligent peripheral control can be realized, more complex operation can be completed between a switch and an actuator, and the gateway can be butted with other intelligent home systems. It will be understood by those skilled in the art that the gateway and each of the enforcement offices have independent ID information, i.e., the ID information of each of the devices is independent and different. Determining a connection relationship through a binding operation, wherein the gateway records ID information of the actuator for function control; wherein the executor checks the gateway ID information for identification.
In the preferred embodiment of the present invention, the gateway and the executor are bound by way of a radio broadcast search. The gateway broadcasts a search instruction, when the actuator receives the search instruction broadcasted by the gateway, the ID information of the actuator is sent, and the gateway records after receiving the ID information of the actuator. The method for binding the gateway and the actuator is automatic in process, a plurality of devices can be bound at one time, namely the gateway can be bound with a plurality of actuators at the same time, and the efficiency is high. In order to avoid mutual interference of ID signals sent by the actuators in the binding process of the gateway and the actuators, after receiving the gateway searching instruction, the actuators delay to send ID information of the actuators, the delay time is a multiple of the signal occupation time, and the word signal occupation time is slightly amplified to the real signal occupation time, so that the signals with different multiples cannot mutually interfere, and only the multiples of different actuators are required to be different. That is, a delay time multiple is generated from ID information of an actuator, and the ID information of the actuator is delayed and transmitted based on the generated delay time multiple.
In the preferred embodiment of the invention, the time-delay random number is obtained by utilizing the wireless function through the environmental noise, and the random number is not required to be generated by a random number generator of the main control unit, so that the structure of the whole wireless control system is simplified, and the cost is reduced.
In detail, the receiver of the smart device will always continuously receive the electromagnetic wave in the network environment and continuously interpret the binary information therein (0101010), when the matching reads the corresponding control command identification code, the command content therein is further read, and the identification code that cannot be matched is usually ignored as a noise signal.
It is worth mentioning that the noise signal is related to various factors such as the network environment, the location of the smart device, weather, time, etc., and even if the same device is located at different locations of the network environment, the received noise signal is different, so that the randomness is very high. It is worth mentioning that the factors affecting the noise signal mainly include the electromagnetic environment of the device and the radio frequency characteristics inside the device. The electromagnetic environment of the device comprises the position of the device and the distribution of surrounding electronic devices, and even if two devices are put together, the two devices can affect the nearby devices due to the electromagnetic radiation of the two devices; the RF characteristics inside the device are also different due to the RF chip process variations and matching device errors, because the randomness is very high. Therefore, in the preferred embodiment of the present invention, when the executor receives the search information broadcasted by the gateway, the executor continues to receive the environmental noise information, and converts the binary data in the received environmental noise signal into the delay random number, so that each intelligent device in the same network environment can send a signal at a wrong peak under the condition of non-interference, thereby greatly reducing the network transmission pressure and alleviating the network congestion condition. That is, the wireless device converts the received noise signal according to a certain rule after receiving the 'state feedback' command from the gateway, and converts the binary data in the noise signal into the delay random number, so that each intelligent device in the same network environment can send signals in a staggered mode under the condition of mutual noninterference, thereby greatly reducing the network transmission pressure and relieving the network congestion condition.
Specifically, the gateway is configured to transmit a signal with a length of N bytes, and the actuator continues to receive an N-byte signal from the environmental noise signal after receiving the N-byte signal. It will be appreciated that the n bytes of data are random signals in the absence of additional high power device interference on the frequency channel, the random data being related to the environment in which the actuator is located, i.e. the internal circuit details.
The data from at least one byte in environmental noise is selected from the N + N bytes received by the actuator to serve as the delay multiple of the actuator at present, the actuator sends self ID information based on the delay multiple, and after the gateway receives the ID information of the actuator, the ID information of the actuator is recorded, so that the gateway is bound with the actuator.
For example, when the number of the actuators is less than 50, the gateway sends out a search command of 8 bytes, and after each actuator receives the 8-byte command sent out by the gateway, the actuator receives a 4-byte command of the environmental noise, that is, the actuator receives data of 12 bytes. And selecting the data of the 10 th byte as a multiple, sending self ID information by the executor, and after the time of the maximum multiple, the gateway can receive the ID information sent by all the executors in the environment, and the gateway can be bound with the executor. Optionally, the executor may select the last byte received as the delay multiple of the executor, or the 9 th bit received as the delay multiple corresponding to the executor.
It should be noted that the number of the above-mentioned actuators, the number of bytes sent by the gateway, the selected bytes corresponding to the environmental noise, etc. are only used as examples and are not limited herein. Therefore, the invention does not limit the number of bytes received by the executor.
And if the executors with the same time delay multiple are not bound, performing the next search again. The gateway broadcasts a search instruction message again at the same time, and the bound executors do not reply the search instruction message, so that only the executors left in the first search (the multiple generation is the same), and the ID information is sent after the executors are randomly searched again, the probability of the multiple repetition is very small, and the binding of all the executors can be basically completed by searching twice.
As shown in fig. 4A and 4B, at the first pairing, the gateway broadcasts a search command for the first time, where actuator 1, actuator 2, actuator 3, actuator 4 …, and actuator n each receive the search command as a separate actuator unit and respectively receive an ambient noise signal. And each actuator respectively obtains corresponding delay random numbers based on the received environment noise signals, wherein the delay random number of the actuator 1 is t1, the delay random number of the actuator 2 is t2, and the delay random number of the actuator 3 is t3 …, and the delay random number of the actuator n is tn. For example, t2 is tn, and the delay random numbers of other actuators are different, so that after each actuator corresponds to a multiple of the delay random number, the identity ID information of each actuator is sent, and after the identity ID information of each actuator is recorded by the gateway, the actuator 1, the actuator 3, the actuator 4, and the like are sequentially matched and connected with the gateway.
And for the actuators which are left as the pairs, the gateway sends a search instruction again, wherein the actuator 2 and the actuator n respectively obtain corresponding delay random numbers based on the received environmental noise signals. Thus, after two-sided searching, the probability of repeating the random number of the second time delay of the actuator 2 and the actuator n is extremely small. Thus, two searches may essentially complete binding for all actuators.
After the gateway is bound with the actuator, the gateway can control the actuator through instructions, including operations of state control, state query, pairing state entering, pairing clearing, contact binding and the like. The gateway is bidirectional in control wireless signals of the actuator, the gateway sends out control signals, the actuator executes operation and replies response signals after receiving the signals, the gateway can repeatedly send the control signals when not receiving the corresponding signals, and the gateway is more reliable in control over the actuator than on-off control.
Accordingly, in the preferred embodiment of the present invention, the gateway of the wireless device control system and a plurality of actuators implement binding pairing by the above method, so that the gateway sends control instructions to the actuators corresponding to the wireless devices. After the switch, the actuator and the gateway are connected in a pairing mode, the switch can send a control command to the actuator through the gateway, or the switch directly sends the control command to the actuator. Accordingly, when the state of the actuator changes, the state feedback instruction of the actuator is fed back to the gateway, and is uploaded to corresponding electronic equipment, such as a mobile phone, a computer, remote control equipment with a network connection function, and the like, through the internet by the gateway.
In the step of connecting the switch and the actuator, the binding relationship between the switch and the actuator is realized by pairing, and a specific switch can control a specific actuator after pairing. The step of pairing the switch and the actuator comprises the steps of: the actuator enters a pairing state; the switch sends a signal of pairing information, and the actuator records the information signal of the switch, so that the pairing connection of the switch and the actuator is realized.
After the actuator and the switch are paired and bound, the switch can directly send a control signal to the actuator after the actuator and the switch are completely paired, and the operating state of the actuator is controlled. Preferably, in this preferred embodiment of the invention, the switch is a wireless controlled switch. More preferably, the switch is a passive wireless control switch, that is, the switch generates electric energy through self action, and the electric energy generated by the switch sends a control signal to the outside.
The connection between the switch and the gateway in the above method further comprises: the bent pipe enters a switch binding state; and the switch sends self ID information, and the gateway records the ID information of the switch so as to realize the binding of the switch and the gateway. Because the gateway is connected with the Internet, after the switch is connected with the gateway, the switch can be connected to the whole network, the switch action can be used as a condition for scene triggering, the linkage operation of each actuator is realized through the gateway, and the linkage operation of other network equipment can be realized through the network.
The wireless device control system controls the working state of the wireless device controlled by the actuator in a wireless network transmission and wireless control mode through the definition of the wireless protocol customization and the device connection. It is understood that the actuator can be set as a relay by the wireless communication principle, the transmission distance of the switch and the gateway to the wireless control signal is enlarged, and the program update of the actuator can be realized by the networking function of the gateway.
Referring to fig. 5 of the drawings of the present specification, according to another aspect of the present invention, the wireless device communication method of the present invention includes a wireless device connection method, wherein the wireless device connection method includes the steps of:
(a) reading a search instruction and receiving an environmental noise signal;
(b) generating a delay random number based on the received environmental noise signal, and delaying and sending ID information of a corresponding actuator according to the delay random number as a multiple; and
(c) and recording the ID information of the actuator to a gateway to realize the pairing connection of the gateway and the actuator.
In the above-described method for connecting a wireless device of the present invention, the method further includes, before the step (a), the steps of: a search instruction is broadcast, wherein the executor is to read the search instruction. Further, the length of the instruction sent by the gateway is N bytes, and the executor receives a signal of N + N bytes, where N bytes correspond to a noise signal of a current environment. In step (b) of the above method, the executor converts the environmental noise signal into a corresponding time-delay random number based on a certain rule. Preferably, any byte of data in the n bytes of signals corresponding to the environmental noise signal is selected as the delay random number.
Preferably, the search instruction broadcasted by the gateway is 8 bytes of information, and the actuator receives 12 bytes of information, where the first 8 bytes are the search instruction broadcasted by the gateway, and the last 4 bytes correspond to the ambient noise information received by the actuator. In the preferred embodiment of the present invention, the 10 th byte of data is selected as the delay random number.
In the connection method of the wireless device of the present invention, the method further includes the step (d) of determining whether all the actuators are not paired and connected, and if yes, repeatedly executing the above steps; if not, the pairing is ended. In the method for connecting a wireless device according to the present invention, the method further includes: recording pairing information of switches to corresponding actuators so that the switches and the corresponding actuators are paired; and recording the ID information of the switch to the gateway so as to realize the binding of the switch and the gateway.
When the number of the wireless devices in an environment is large or the number of the actuators of the wireless devices is large, network signal congestion is also easily caused when the states of the actuators are changed to feed back to the gateway. Correspondingly, when the state of the actuator changes, the actuator sends the state feedback information of the actuator in a method of delaying random numbers, so that the situation that information is fed back by a plurality of actuators at the same time to cause information blockage is avoided.
In detail, when the state of the actuator changes, the state information of the actuator needs to be fed back to the gateway, so that the gateway records the current state information of the actuator. The executor combines self ID information and state feedback information and receives environmental noise information; the actuator converts the received noise information into a delay random number corresponding to the actuator delay transmission data according to a certain rule; and the executor delays and sends the ID information and the state feedback information of the executor to the paired gateway based on the delayed random number, and the gateway records the current state information of the executor.
When the state of the actuator changes, the actuator receives noise information in the environment and converts the noise information into corresponding m bytes. It will be appreciated that the n bytes of data are random signals in the absence of additional high power device interference on the frequency channel, the random data being related to the environment in which the actuator is located, i.e. the internal circuit details.
The data of at least one byte in the m bytes received by the actuator is selected as the delay multiple of the actuator at present, the actuator sends self ID information and corresponding state feedback information based on the delay multiple, and the gateway records the corresponding state feedback information after receiving the ID information of the actuator so as to update the state information of the actuator. The gateway updates the state information which is originally recorded in the remote electronic equipment and corresponds to the actuator through the Internet, so that the remote electronic equipment can acquire the working state change of the current actuator.
For example, when the state of the actuator changes, the actuator receives an ambient noise signal and converts the ambient noise signal into a 4-byte instruction according to a certain rule. And selecting any byte of data in the 4 byte instructions as a multiple, and sending self ID information and the actuator state information by the actuator. Theoretically, after the maximum multiple time, the gateway can receive the state change information sent by all the actuators in the environment, and the network updates the state change information of each actuator. Preferably, the 2 nd or 3 rd byte data is selected as the delay random number of the current actuator. Optionally, the executor may select the first or last byte received as a multiple of the delayed random number of the executor.
Referring to fig. 6 of the drawings accompanying the present specification, the present invention further provides an actuator state feedback method of a wireless device control system, wherein the actuator state feedback method comprises the steps of:
(1) receiving an environmental noise signal, and converting the environmental noise signal into a corresponding delay random number;
(2) the ID information and the corresponding state change information of the actuator are sent in a delayed mode based on the delayed random number; and
(3) and recording the state change information of the actuator to a gateway to realize the state feedback of the actuator.
In the above method for feeding back the state of the actuator, when the state of the actuator changes, the actuator receives noise information in the environment and converts the noise information into corresponding m bytes, and the data of at least one byte in the m bytes received by the actuator is selected as the delay multiple of the actuator at present. Preferably, when the state of the actuator changes, the actuator receives an environmental noise signal, converts the environmental noise signal into a 4-byte instruction according to a certain rule, selects any byte of data in the 4-byte instruction as a multiple of the delay random number, and sends the ID information of the actuator and the state information of the actuator. Preferably, in the preferred embodiment of the present invention, the data of the 2 nd or 3 rd byte is selected as a multiple of the delay random number.
According to another aspect of the present invention, the actuator of the wireless device of the present invention may be used as a repeater to receive the control signal and transmit the control signal to the outside to extend the control distance of the switch or gateway. In other words, the actuators of the wireless devices may be interconnected so that control commands sent by the switches or the gateway are conducted by the actuators; or the actuator transmits the state feedback information to the gateway to realize remote transmission.
When a plurality of actuators receive signal commands at the same time and each actuator serves as a relay to send the signal commands to the outside, other actuators may receive the signal commands sent by a plurality of different actuators at the same time, thereby causing signal blockage.
Accordingly, in the preferred embodiment of the present invention, the actuator realizes the relay function of the actuator by generating the delay random number through the environmental noise. In detail, when the actuators receive control command information of the switches, each actuator continues to receive environmental noise information after reading the control command of the switches. The actuators are converted into delay random numbers according to a certain rule based on the received environmental noise information, and each actuator transmits the control instruction in a delay mode based on the respective delay random number.
It should be noted that, in the present invention, one of the actuators may serve as a relay to send out a control command of the switch to a plurality of other actuators, or a plurality of the actuators may serve as a relay to send out a control command of the switch to other actuators. When each actuator is used as a relay, the random delay numbers obtained by the actuators based on the environmental noise are different, and the control information is sent out in a delayed manner by different delay numbers, so that the data jam is reduced. The actuator is used as a repeater to receive the control command of the switch, and the control signal is amplified and then sent out by the actuator, so that a remote actuator can receive the control command sent by the switch.
And setting the switch to send a control instruction signal with the length of X bytes, and after receiving the control instruction signal with the length of X bytes, the actuator continues to receive the signal with the length of X bytes from the environmental noise signal. It will be appreciated that the x bytes of data are random signals in the absence of additional high power device interference on the frequency channel, the random data being related to the environment in which the actuator is located, i.e. the internal circuit details.
And selecting data from at least one byte in the environmental noise from the X + X bytes received by the actuator as the delay multiple of the current actuator, and sending the control command signal by the actuator based on the delay multiple so that other actuators can receive the control command signal relayed by the current actuator.
For example, when the number of the actuators is less than 50, the switch sends out a control command of 8 bytes, and each actuator receives a 4-byte command of the environmental noise after receiving the 8-byte command sent out by the gateway, that is, the actuator receives 12 bytes of data. And selecting the data of the 10 th byte as a multiple, sending the received control instruction by the actuator, and after the time of the maximum multiple, receiving the control instruction information sent by the actuator which is currently used as a repeater in the environment by other actuators. Optionally, the executor may select the last byte received as the delay multiple of the executor, or the 9 th bit received as the delay multiple corresponding to the executor.
It should be noted that the number of the above-mentioned actuators, the number of bytes sent by the gateway, the selected bytes corresponding to the environmental noise, etc. are only used as examples and are not limited herein. Therefore, the invention does not limit the number of bytes received by the executor.

(I) reading a control instruction and receiving an environmental noise signal; and
