The technical problems that the operation load of the internet of things terminal is increased and the electric quantity is wasted when the internet of things terminal transmits data in real time are solved. In one embodiment, an internet of things terminal is provided. The network framework of the internet of things shown in fig. 1 comprises a server, a gateway, M access points, N repeaters and a plurality of internet of things terminals, wherein the access points are connected with the gateway through the ethernet or network forms such as 2G, 3G and 4G, the repeaters are connected with the plurality of internet of things terminals and the access points, the internet of things terminals transmit collected data through the repeaters, and the data are uploaded to the server through the access points and the gateway equipment to exchange the data. Similarly, the terminal of the internet of things receives data sent by the server through the gateway device, the access point or the repeater.
The terminal of the internet of things disclosed by the invention only receives and/or sends data, and receives and/or sends the data at regular time, namely, the terminal of the internet of things only receives and/or sends the data within specific time, and does not work in other time.
Specifically, as shown in fig. 2, a method for transmitting data by an internet of things terminal includes:
step S102: and generating a transmission starting instruction when a preset first period duration arrives.
The internet of things terminal comprises a transmission starting module, the transmission starting module can comprise a timer, and when a preset first period duration arrives, a transmission starting instruction is generated and comprises an equipment identifier, a cache file list, a network state and the like of the internet of things terminal.
Optionally, the first period duration is a preset period duration or a period duration of a heartbeat packet communicated between the internet of things terminal and the internet of things server.
The preset period duration may be 20 seconds, 1 minute, 5 minutes or self-defined by the user setting the first period duration in the "timing time" tab, and the default setting is 20 seconds. And the heartbeat packet is a time period of message interaction specified between the terminal of the internet of things and the server of the internet of things, the frequency is similar to the heartbeat, and the default is 10 seconds.
For example, if 1 minute is set as the heartbeat packet, the internet of things terminal sends the acquired data to the internet of things server every 1 minute, or the internet of things terminal receives the data sent by the internet of things server every 1 minute.
Step S104: and establishing network connection with a remote Internet of things server.
And after receiving the transmission starting instruction, connecting the Internet of things terminal with the Internet of things server. That is to say, there is the connection module at thing networking terminal, and thing networking terminal just can carry out data interaction with thing networking server when receiving and open transmission instruction, and thing networking terminal does not carry out any transmission operation in the rest of time.
Step S106: and transmitting the data to be transmitted with the Internet of things server through the network connection.
And after the connection between the Internet of things terminal and the Internet of things server is established, transmitting the data to be transmitted with the Internet of things server through network connection.
In order to further reduce the power consumption of the Internet of things terminal, the equipment identification of the Internet of things server is verified, the Internet of things server which passes the verification can be connected with the Internet of things terminal, and the data to be transmitted is determined according to the transmission speed between the Internet of things terminal and the Internet of things server.
The internet of things server stores a series of internet of things terminals and corresponding equipment identifications according to the type of the transmission data, sends verification information to the internet of things terminals after the internet of things server is connected with the internet of things terminals, and verifies successfully when the verification information is matched with preset verification information of the internet of things terminals.
The preset verification information of the terminal of the internet of things, namely the equipment identifier of the terminal of the internet of things, refers to identification information which is arranged in a chip of the terminal equipment of the internet of things and is used for distinguishing other equipment, and the identification information cannot be changed after the equipment leaves a factory, and comprises information such as a serial number of a manufacturer, a model of the equipment, an MAC address of the equipment and the like. And generating the equipment authentication code according to the equipment identification information, namely converting the information into a character code form, such as a specific format of 'serial number-model number-MAC address', and facilitating the reading of other equipment.
The terminal of the Internet of things is a device which is connected with a sensing network layer and a transmission network layer in the Internet of things and used for acquiring data and sending the data to the network layer, and different device identifications are used for distinguishing different devices. For example, the device identifier of the terminal of the internet of things may be a MAC address of the terminal of the internet of things, where the MAC address is also called a physical address or a hardware address, and is used to define the location of the network device, the date of accessing the internet of things may be added with the terminal type, or a default name of the terminal of the internet of things by a computer program, or a combination of the terminal type and a number, or a name of the terminal of the internet of things saved by a user. It should be noted that the device identifier of the terminal of the internet of things in one internet of things should have uniqueness.
In combination with a specific embodiment, as shown in fig. 3, there are 1 gateway, 1 access point, and 3 internet of things terminals at a node of the internet of things, which are an internet of things terminal J, an internet of things terminal K, and an internet of things terminal L, respectively. And generating a device authentication code according to the device identification information, wherein the device authentication code of the terminal J of the Internet of things is '001-A1070-00010010', the device authentication code of the terminal K of the Internet of things is '011-BC 79-00101100', and the device authentication code of the terminal L of the Internet of things is '001-D1008-10010110'. It is assumed that only the terminal L of the internet of things is the terminal of the internet of things disclosed in the embodiments of the present invention, that is, the terminal L of the internet of things transmits data with the server of the internet of things at a specific time. After the Internet of things server is connected with the Internet of things terminal J, the Internet of things terminal K and the Internet of things terminal L, the Internet of things server sends verification information to the Internet of things terminal, and the verification information is '001-D1008-10010110'. And if the fact that the Internet of things terminal connected with the Internet of things server is the Internet of things terminal L is known through verification, the Internet of things terminal L transmits data to be transmitted. Therefore, the power consumption of the terminal of the Internet of things is reduced.
Optionally, after the connection is established, because a certain time is required for transmission, the data to be transmitted can be divided into a plurality of data packets with specific sizes, and the data packets are transmitted in sequence, so that the transmission process is accelerated, and the power consumption of the terminal of the internet of things is reduced. The method specifically comprises the following steps: acquiring verification information sent by the Internet of things server, and executing the step of establishing network connection with a remote Internet of things server when the verification information is matched with preset verification information; acquiring and detecting the transmission speed of the Internet of things server to the Internet of things terminal; determining the size of a cache space according to the transmission speed; writing the data to be transmitted into the cache space, and determining first backup data contained in the cache space; and when the first backup data reach the size of the cache space, transmitting the first backup data to the Internet of things terminal.
The data to be transmitted comprises the data itself, and also comprises the name of the data to be transmitted, the data type, the relative path stored on the terminal of the internet of things and other data basic information. When the data to be transmitted is written into the first cache space, the first backup data package contains the data to be transmitted and the data basic information of the data to be transmitted.
And determining the size of the cache space according to the transmission speed, and sequentially transmitting, thereby accelerating the transmission process and reducing the power consumption of the terminal of the Internet of things. For example, if the transmission speed between the internet of things terminal and the internet of things server is 2M/s, the size of the cache space can be determined to be 10M, 10M data to be transmitted is acquired as first backup data, and the first backup data is transmitted to the internet of things terminal; and then 10M data to be transmitted is acquired as second backup data, the second backup data is transmitted to the terminal of the Internet of things, and the like, so that the data transmission efficiency and the storage space utilization rate are improved.
Step S108: and when the preset second period duration arrives or the transmission of the data to be transmitted is finished, disconnecting the network connection with the Internet of things server.
The second period duration may also be a preset period duration or a period duration of a heartbeat packet of the internet of things terminal communicating with the internet of things server. As with the first period of time, the predetermined protocol may be that the user sets the time for the receive time period in the "timed" tab to be 20 seconds, 1 minute, 5 minutes, or custom, with a default setting of 20 seconds. The heartbeat packet is a time period of message interaction specified between the internet of things terminal 10 and the internet of things server 108, the frequency is similar to the heartbeat, and the default is 10 seconds.
Optionally, the second period duration is determined by a control parameter, where the control parameter includes a transmission bandwidth occupancy rate or a packet loss rate of the data to be transmitted; and when the transmission bandwidth occupancy rate or the packet loss rate is greater than a first threshold value, prolonging the second period time, thereby improving the effectiveness of data transmission.
And when the occupancy rate of the transmission bandwidth of the network is low, the current network is considered to be in a network idle state and is suitable for network transmission. And when the transmission bandwidth occupancy rate of the network is high, the network transmission speed is low, the efficiency is low, and the second period time can be prolonged.
For example, assuming that the first threshold of the transmission bandwidth occupancy is 80%, the second cycle duration is set to 30 seconds. When the occupancy rate of the transmission bandwidth is 95%, the duration of the second period needs to be extended, and the duration of the second period is set to 50 seconds.
And when the packet loss rate of the network is high, the accuracy of the current transmission data is considered to be low, and the second period duration is prolonged. Assuming that the first threshold of the packet loss rate is 80%, the second period duration is set to 30 seconds. And if the packet loss rate is detected to be 89%, the second period time needs to be prolonged, and the second period time is set to be 40 seconds.
For another example, assuming that the duration of the second period is 10 seconds, the transmission speed is faster 20M/s, the size of the currently transmitted data capacity is 30M, and the duration of the second period is set to 2 seconds according to the transmission speed.
As a special example, assuming that the second threshold is 5M, when the duration of the second period does not reach, after the transmission of the data to be transmitted is completed, the network connection is disconnected with the internet of things server, so as to ensure that the transmission of the data to be transmitted is completed.
In addition, in the second period duration, if the transmission data needs to be modified, the second period duration can be extended. Specifically, the command for modifying the received data is received, and the duration of the second period is prolonged.
For example, the second cycle duration is 5 seconds, and when the second cycle duration is received before arrival (assuming the first 2 seconds), the second cycle duration is set to 20 seconds.
Furthermore, the control parameter may be a data type or a capacity size, or the like. That is, the second period duration may also be determined by a priority determined by a data type or a capacity size of the received data.
The transmission sequence of the effective data is determined according to the data type of the data to be transmitted and the preset threshold interval, and the effective data is transmitted, so that the data transmission efficiency is improved, and the power consumption of the terminal of the Internet of things is reduced. The method specifically comprises the following steps: searching the data to be transmitted which meet a preset threshold interval as effective data, and determining the transmission sequence of the effective data according to the data type of the effective data; transmitting the effective data through the network connection according to the transmission sequence of the effective data; the method further comprises the following steps when the preset second cycle duration arrives or the belt transmission data transmission is finished: and generating a data report according to the uploading time of the effective data and the data type.
The internet of things terminal in the intelligent home scene comprises a mobile terminal, a game machine, a television, a computer, an electronic lock anti-theft door, a refrigerator, a washing machine and the like. For example, assuming that the preset threshold interval is 1M to 5M, since the transmission capacity of the game machine is 0.02M, the computer is 5M, the electronic lock security door is 0.2M, the refrigerator is 3M, and the washing machine is 4M, valid data obtained through the preset threshold interval are data of the computer, the refrigerator, and the washing machine, and the data report displays the data capacity of the computer, the refrigerator, and the washing machine.
As another example, the data report generated by the data included in the washing machine 4M data is shown in fig. 4, and the time is 9:00 to 9:50, and assuming a first cycle duration of 5 minutes, data is transmitted every 5 minutes, from which data file reports it can be seen that water is being taken in from 9:00 to 9:05, water is being taken in from 9:05 to 9:16, spin is being taken from 9:16 to 9:21, water is being taken from 9:21 to 9:26, water is being taken from 9:26 to 9:41, spin is being taken from 9:41 to 9:46, that is to say the time taken for water to be taken in and spin is 5 minutes, the time taken for the first wash is 11 minutes, and the time taken for the second wash is 15 minutes. The reading data report can fully know the working condition of the washing machine, and is beneficial to self-defining the washing program and reasonably utilizing the time.
Optionally, when the data type of the data to be transmitted is an emergency reception type, that is, its priority is the highest priority, the data to be transmitted is preferably transmitted.
Optionally, the receiving status of the data to be transmitted after transmission is marked as received; taking the data to be transmitted which is not received in the receiving state as target data; and transmitting the target data to the Internet of things server through the network connection.
In the method for transmitting data in the internet of things depicted in fig. 2, when a preset first period duration arrives, a transmission start instruction is generated; establishing network connection with a remote Internet of things server; transmitting data to be transmitted with the Internet of things server through the network connection; and when the preset second period duration arrives or the transmission of the data to be transmitted is finished, disconnecting the network connection with the Internet of things server. Because data are transmitted only in specific time, data are transmitted in a centralized mode, and the data do not work in other time, on one hand, electricity is saved, on the other hand, the operation load of the Internet of things terminal is reduced, and the message interaction between the Internet of things server and the Internet of things terminal is reduced, so that the operation efficiency and the endurance time of the Internet of things terminal are improved.
The technical problems that the operation load of the internet of things terminal is increased and the electric quantity is wasted when the internet of things terminal transmits data in real time are solved. In one embodiment, a method for transmitting data by an internet of things terminal is provided. As shown in fig. 5, the apparatus for transmitting data by the terminal of internet of things includes:
