Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to the accompanying drawings 1 to 5, a doorbell system 200 and a communication method 100 of the doorbell system are illustrated, wherein the doorbell system 200 comprises at least one doorbell assembly 21, a communication base 22 and an intelligent terminal 23, wherein the at least one doorbell assembly 21 is adapted to be installed outside a door, and the at least one doorbell assembly 21 is adapted to be communicatively connected to the communication base 22, and the communication base 22 is adapted to be communicatively connected to the intelligent terminal 23. The doorbell component 21 can send the acquired information data to the communication base station 22, and the communication base station 22 sends the acquired information data to the intelligent terminal 23, so as to give out a prompt to a user of the doorbell system 200. It is understood that the smart terminal 23 includes, but is not limited to, a smart phone, a computer, a smart wearable device, and smart furniture.
Further, the doorbell assembly 21 has an awake state and an awake state, wherein in the awake state, the doorbell assembly 21 is triggered, for example, pressed by a person outside the door, the doorbell assembly 21 collects environment information of a predetermined space outside the door, the environment information includes but is not limited to image information and sound information outside the door, and sends the environment information to the communication base station 22 by wireless transmission; in the non-awake state, the doorbell component 21 is not triggered, and the doorbell component 21 acquires state information of itself, such as electric quantity and working parameters, and sends the state information to the communication base station 22 through a 433MHz wireless frequency band. The communication base station 22 can send the acquired environment information and the acquired state information to the intelligent terminal 23, so that a user can acquire the environment information and the state information conveniently.
Specifically, the environmental information collected by the doorbell component 21 is sent to the communication base station 22 by way of wireless communication with a frequency band of 2.4G or 5G. It can be understood that the doorbell assembly 21, as a reminder device installed outdoors, may be in the not-wakening state for a long time, when the doorbell assembly 21 is in the not-wakening state, the status information of the doorbell assembly 21 is sent through the 433MHz wireless frequency band with low power consumption, which can reduce the energy loss during the information sending process, and can meet the requirement of remote transmission.
Correspondingly, the doorbell assembly 21 further comprises a first communication unit 211, and the communication base 22 further comprises a second communication unit 221, wherein the environmental information collected by the doorbell assembly 21 and the status information of the doorbell assembly 21 can be sent to the second communication unit 221 by the first communication unit 211.
It is expected that the 433MHz communication is still not driven well, and when one communication base station 22 corresponds to a plurality of doorbell assemblies 21 or a plurality of groups of doorbell systems 200 exist in the same space, data is likely to collide in the channel transmission process, which results in data transmission failure and affects the normal use of the doorbell systems 200. For example, since the data of different doorbell assemblies 21 are transmitted to the communication base station 22 in the same channel, since the communication capacity of one channel is limited, when the total amount of data of different doorbell assemblies 21 is greater than the total communication capacity of the channel, a part of the data is inevitably lost. On the other hand, even if the communication capacity of the same channel can meet the transmission requirement of the total amount of data of different doorbell assemblies 21, when the data of different doorbell assemblies 21 are transmitted in the same time slice, the data still cannot be successfully transmitted due to collision.
In order to prevent the data transmission failure of the doorbell system 200 caused by the collision during the transmission process, in the process of transmitting the status information of the doorbell assembly 21, the channel for transmitting the status information is selected, and when the data in the same channel is collided, the time slice is delayed to prevent the collision between the data, so as to ensure that the status information is effectively transmitted.
Specifically, the communication base station 22 further comprises a free channel determination unit 222, wherein the free channel determination unit 222 is configured to determine a free channel of a plurality of channels of the communication base station 22, so that the status information of the doorbell component 21 can be transmitted on the free channel. When the idle channel determining unit 222 determines the idle channel, the idle channel is sent to the doorbell component 21, so that the doorbell component 21 sends the status information of the doorbell component 21 to the communication base station 22 through the idle channel. That is, the status information of the doorbell component 21 is sent by the first communication unit 211 to the second communication unit 221 on the idle channel.
It should be noted that, after the idle channel determining unit 222 determines the idle channel, the second communication unit 221 sends the idle channel to the first communication unit 211 of the doorbell assembly 21 by way of wireless communication with a frequency of 2.4G or 5G, so as to increase the transmission speed and increase the response speed of the doorbell assembly 21.
Specifically, the idle channel determination unit 222 further includes a channel reading module 2221, a data detection module 2222, and a channel determination module 2223, wherein the channel reading module 2221 is configured to read a first channel pre-stored in a plurality of channels of the communication base station 22; after the first channel is read, the data detecting module 2222 is configured to detect whether data is transmitted on the first channel, and when it is detected that no data is transmitted on the first channel, the channel determining module 2223 determines the first channel as the idle channel; when detecting that there is data being transmitted on the first channel, the data detecting module 2222 detects the number of data packets transmitted in a preset unit time in the first channel; when the number of data packets transmitted by all channels of the communication base station 22 in the preset unit time is detected, the channel determining module 223 determines that the channel with the least number of data packets received in the preset unit time in all channels of the communication base station 22 is the idle channel; wherein not all channels of the communication base station 22 are detected to transmit the number of data packets in the preset unit time, and sequentially determining whether data is transmitted in the undetected channel and the number of data packets transmitted in the preset unit time.
In other words, when there is no data transmission in the first channel of the communication base station 22, the first channel is determined as the idle channel; when there is data transmission in all channels of the communication base station 22, the channel with the least amount of data transmission in all channels of the communication base station 22 is determined as the idle channel, so that the status information of the doorbell assembly 21 can be transmitted efficiently.
Further, the communication base station 22 further includes a storage unit 223, after the idle channel determining unit 222 determines the idle channel, the storage unit 223 can store the idle channel and the doorbell corresponding to the idle channel, so that the doorbell system 200 can read the stored idle channel when starting up next time. It is understood that the first channel is the free channel stored the last time the doorbell system 200 was shut down.
Specifically, the length of the preset unit time that determines the number of received packets in the preset unit time in each channel of the communication base station 22 is 3 seconds. Alternatively, the length of the preset unit time can be other time lengths.
Further, the doorbell component 21 further comprises an idle time slice determination unit 212, the idle time slice determination unit 212 being configured to determine an idle time slice corresponding to the doorbell component 21 and the idle channel, such that the status information of the doorbell component 21 does not collide with other data packets when the idle time slice is sent in the idle channel, such that the status information of the corresponding doorbell component 21 can be efficiently transmitted.
Specifically, the idle time slice determining unit 212 further includes a time slice reading module 2121, a collision detecting module 2122, a time slice determining module 2123, and a random delay module 2124.
The time slice reading module 2121 is configured to read a first time slice in the idle channel. After the time reading module 2121 reads the first time slice in the idle channel, the doorbell component 21 sends the status information of the doorbell component 21 to the communication base station 22 at a preset frequency in the first time slice of the idle channel.
The collision detection module 2121 is configured to detect whether the sending of the status information of the doorbell assembly 21 in the first time slice of the idle channel is successful. I.e. for detecting whether the data transmitting the status information of the doorbell assembly 21 in the first time slice of the free channel collides with other data. And when the state information is successfully transmitted, the collision with other data is not generated, and when the state information is unsuccessfully transmitted, the collision with other data is generated.
When the collision detection module 2121 detects that the status information is unsuccessfully transmitted in the first time slice of the idle channel, it determines whether the number of times of transmitting the status information corresponding to the first time slice to the communication base station 22 is within a preset number of times; when the number of times of sending the state information corresponding to the first time slice to the communication base station 22 is within the preset number range, the random delay module 2124 delays the first time slice by combining the first time slice with a random value within a preset time range to obtain a second time slice, and sends the state information corresponding to the first time slice to the communication base station 22 again at the second time slice by using the preset frequency. When the number of times of sending the status information corresponding to the first time slice to the communication base station 22 is not within the preset number range, it is determined that the sending of the status information corresponding to the first time slice fails.
When the collision detection module 2121 detects that the status information is successfully transmitted in the first time slice of the idle channel, it determines whether the time slice corresponding to the successful transmission of the status information to the communication base station 22 is the first time slice; when the time slice corresponding to the successful transmission of the status information to the communication base station 22 is not the first time slice, the time slice determining module 2123 determines the time slice corresponding to the successful transmission of the status information to the communication base station 22 as the idle time slice; when the time slice corresponding to the successful transmission of the status information to the communication base station 22 is the first time slice, the time slice determining module 2123 determines the first time slice as the idle time slice.
The doorbell component 21 sends the status information of the doorbell component 22 to the communication base station 22 through the idle channel in the idle time slice at the preset frequency that one second is used as an interval to send data packets to the communication base station 22 for taking account of response speed and low power consumption. Alternatively, the preset frequency can also be implemented as another frequency value.
Specifically, the first time slice is delayed by combining the first time slice with a random value in the preset time range to obtain a second time slice, where the preset time range is 50ms to 300ms, that is, the random time value is taken in the time range of 50ms to 300ms to be combined with the first time slice to delay the first time slice to obtain the second time slice, and the state information corresponding to the first time slice is sent again in the second time slice.
It should be noted that, in the same channel, after different data have undergone multiple collisions and random delays, multiple doorbell assemblies 21 corresponding to the same communication base station 22 or multiple doorbell systems 200 can communicate with each other in their respective time slices, so that the probability of collision of subsequent data can be greatly reduced.
It should be further noted that, in the preferred embodiment, when two sets of data collide, the time slices corresponding to the two sets of data are respectively delayed randomly, so as to effectively stagger the time slices corresponding to the two sets of data. Optionally, when two sets of data collide, only the time slice corresponding to one set of data can be randomly delayed.
Referring to fig. 4 of the specification, in order to better illustrate the present invention, the number of the doorbell assemblies 21 is implemented as three, three doorbell assemblies 21 are a first doorbell assembly, a second doorbell assembly and a third doorbell assembly, respectively, and the first doorbell assembly, the second doorbell assembly and the third doorbell assembly communicate with the communication base 22 on the same channel, respectively.
When a first state information x1 corresponding to the first doorbell assembly collides with a second state information x2 corresponding to the second doorbell assembly, 80ms delay is randomly made for a time slice sending the first state information x1, and 280ms delay is randomly made for a time slice sending the second state information x2, so that the first state information x1 and the second state information x2 are staggered, and the first state information x1 is prevented from colliding with the second state information x 2.
