Fig. 1 is a flowchart of rf communication methods for an intelligent switch according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention .
Referring to fig. 1, a method for rf communication of an intelligent switch, comprising the steps of:
firstly, an intelligent household electronic switch control system is the current technical development situation in the industry and the application scene of an intelligent household system, a low-power consumption personal area network protocol Zigbee based on the IEEE802.15.4 standard is selected, the Zigbee is short-distance and low-power consumption wireless communication technologies, the intelligent household electronic switch control system is characterized by short distance, low complexity, self-organization, low power consumption, low data rate and low cost, the intelligent household electronic switch control system is mainly suitable for the fields of automatic control and remote control, various devices can be embedded, the intelligent household electronic switch control system has the advantages of low cost and low power consumption as short-distance wireless networking communication technologies, the remote control is realized through a GSM module, meanwhile, the economy and the reliability are fully considered, the intelligent household electronic switch control system is designed and developed, when the intelligent household electronic switch control system is used, a user sends a control;
the information receiving module integrates short message receiving, network information receiving and local Zigbee information receiving, and converts the information from the three sources into information in a system format used in the system through information analysis, so that the subsequent operation is facilitated.
The short message command receiving process uses a general GSM short message protocol, comprises a GSM short message sending method and a GSM short message receiving method, is only responsible for receiving and sending short message contents, does not analyze the contents in the short messages, and is completed by an information analysis module.
The network command uses socket communication, and in order to ensure the security of the system, firstly, login verification process based on user name and password is carried out through an information analysis module, and then control signaling is interacted through a socket channel.
The method comprises the steps that local Zigbee message receiving is carried out based on a special Zigbee communication module, the Zigbee modules are divided into a central node mode and a terminal node mode, only central nodes are connected to a GSM intelligent gateway, Zigbee modules embedded in other household appliances are in the terminal node mode, a network ID is a network segment to which the Zigbee modules belong, Zigbee must be set to be in the same network segment to be capable of communicating with each other, a default network segment is FF, in order to prevent signals of a system from interfering with each other, network segments of intelligent household related equipment are set to be in other values, source address output of the central node is selected to be output, therefore, a mac address of a sending source can be seen in Zigbee data received by the central node, the terminal node sets the item to be not output, each terminal node only keeps to communicate with , and does not need to judge the mac address.
Then, the intelligent gateway analyzes the control instruction by using an information analysis module, and the module verifies whether the short message user is an authorized user through short message analysis verification, network information analysis verification and local Zigbee information analysis verification; verifying whether the network command password is correct; and verifying the household appliance information.
Short message analysis and verification process:
(1) and obtaining the mobile phone number field from the short signal code field.
(2) It is verified whether the cell phone number field corresponds to the pre-stored cell phone number .
(3) to enter the appliance control module.
(4) Otherwise the data is discarded.
Network information analysis and verification process:
(1) and analyzing the user name and the password field from the network information.
(2) The username and password fields are verified to match the pre-stored username and password fields .
(3) to enter the appliance control module.
(4) Otherwise the data is discarded.
The local Zigbee information analysis and verification process comprises the following steps:
(1) and analyzing the household appliance name from the Zigbee information.
(2) And searching the equipment list to obtain the corresponding mac address.
(3) And judging whether the mac address is found, successfully returning to 1, and failing to return to 0.
After the analysis is finished, the Zigbee module communicates with a related Zigbee module, returns data to the GSM intelligent gateway after receiving the instruction, sends the instruction to the household appliance control module through an I/O (input/output) port of the Zigbee module, and controls the working state of the switch type household appliances through the relay circuit so as to save energy.
The GSM intelligent gateway sends a command signal character string, writes the command signal character string into a serial port where the zigbee equipment is located, targets the mac address of a zigbee module, and checks a state command, wherein the command character string comprises an actual operation command; the command parameters, command contents and data headers are distinguished by separators.
After the command is sent to the terminal node, the terminal node sets the source address not to output, so the terminal node receives the general signal format.
Then the single chip computer analyzes the signal to control the household appliance.
Taking the control of the air conditioner as an example, if the household appliance with mac address ABCDEF00 receives the command, the household appliance is the air conditioner, and the status command 00 is determined to be the check status command, the household appliance does not perform any control operation, and the household appliance status is directly returned.
And transmitting the household appliance information signal in a format as follows:
&A1&1&+27&23&01&FF&0&0\r\n
among the above signals: each state value is divided by a value A1, wherein the value A represents the type of the household appliance, and the value A refers to a household appliance type definition table, wherein the value A is a value returned by a single chip microcomputer embedded in different household appliances; 1 represents the switch state of the household appliance, +27 represents the current temperature, 23 represents the temperature set by the user, 01 represents the current mode, FF is data which is not acquired, F is used for complementing, and the latter two 0 represent the wind speed and the wind direction.
The data format is a format sent by the terminal node, the source address of the terminal node is set to be not output, the default sending target is the central node, only the content of the following message is filled, and the zigbee modules of data such as the frame header, the length, the mac address and the like can be automatically added. At this time, the intelligent gateway receives the following signals:
0136ABCDEF00&A1&1&+27&23&01&FF&0&0\r\n
for example, after receiving the signal character string, the PC end completes the information of the frame header, mac address, etc., thus completing the control and result acquisition of the home appliance.
The system comprises the following components:
AC/DC power supply circuit: the 220V alternating current is converted into 5V direct current.
A level conversion module: the ZIGBEE module mainly comprises MAX232 chips and an auxiliary circuit, the 5V level is converted into 3.3V, the TTL level of the ZIGBEE module is 3.3V, the TTL level of the CPU is 5V, and two ends are conveniently butted through the two 232 chips.
A ZIGBEE module: the ship SZ05-STD and the GSM communication module gateway realize wireless communication.
A CPU module: STC89C52 singlechip.
