And the second step is that the master receives the responses of the plurality of slaves to the inquiry signals and records the address information of the slave which has responded, the master receives the response signals after the inquiry signals sent by the master are responded by the slaves in the last step, the received information contains the address information of the slave which responds, and the master also records the address information of the slave which responds when receiving the response signals. And thirdly, the host computer sends the recorded address signal of the slave computer which has responded to the user side, and in the step, the host computer executes a sending task and sends the address information of the slave computer to the client side. And finally, the automatic addition of the address information of the slave computer on the client is realized, so that the problem that the process of manually adding the slave computer to the host computer is too complicated is effectively solved.
Further, the master sends inquiry signals to the plurality of slaves, including: the master machine sequentially sends inquiry data packets to each slave machine according to the slave machine address information; the inquiry packet includes: address information of the destination slave, and inquiry information inquiring whether the slave exists.
In the embodiment of the present application, the master sends the inquiry packets to each slave in a certain order, specifically, the inquiry packets are sent in the order of the address information of the slave, and the inquiry is sequentially made to the slave. The present embodiment describes the specific content of the data packet in detail, and besides the address information, there is also a query message for communicating the query for the presence of the slave to the slave. In an optional example, the address information of the slave includes a number of the slave, and the number of the slave is obtained when the slave leaves a factory.
In an alternative example, the number of the slave in the technical solution of the present application may adopt the SN number of the slave product or the last several bits of the SN number. In the embodiment, the slave machine number is not changed, and when the slave machine leaves the factory, the SN number is already solidified in the slave machine, so that the SN number cannot be changed, the slave machines without the same number in the same network can be ensured, and the communication can be prevented from generating collision.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic diagram illustrating steps executed by a host-side method according to an embodiment of the present application, as shown in fig. 1, the method includes:
step 101: the master sends interrogation signals to the plurality of slaves.
In the specific implementation process of step 101, the master is a part of an irrigation device including a master and a plurality of slaves for irrigation implementation, and in this step, a signal transmission function is executed, the signal transmission may be a one-to-one accurate transmission or a one-to-many transmission at the same time, and the master may simultaneously transmit inquiry signals to a plurality of possible slaves in a certain order.
Step 102: and the master machine receives the responses of the plurality of slave machines to the inquiry signals and records the address information of the slave machines which have responded.
In the specific implementation process of step 102, the master performs a receiving task, specifically, responses to signals sent by the plurality of slaves, where the signals are responses to the inquiry signals sent by the slaves after receiving the inquiry signals sent by the master in the previous step, and are referred to as response signals, the response signals include address information of the relevant slaves responding, and the master also records the address information of the slaves while receiving the response signals.
Step 103: and the host sends the recorded address information of the responded slave to the user side.
In the specific implementation process of step 103, the host already receives the response signal of the slave in response and records the address information of the corresponding slave in the previous step, and in this step, the host needs to execute a sending task, the sending target in this step is the user side, and the host sends the response signal of the corresponding slave recorded in the previous step to the user side.
In an embodiment of the present invention, in step 101, the master sends inquiry signals to the plurality of slaves, and during the sending of the inquiry signals, the master sends inquiry packets to each slave according to the slave address information in sequence. The content of the inquiry packet includes address information of the target slave and inquiry information on whether the target slave exists. The master sends inquiry data packets to the possible slaves according to the address information, and sends inquiries to the corresponding slaves by using the content in the data packets. The master can send signals to each possible slave in a one-to-one manner or in a random order, or can send signals one to many at the same time, and the signals are sent in a certain order. The address information of the slave includes the number of the slave, in this embodiment, the number of the slave can be used as one of the address information of the slave, and the specific corresponding slave can be easily obtained according to the number of the slave. In an embodiment of the invention, the number of the slave is already obtained when the slave leaves the factory, preferably, the number of the slave is the last four digits of the SN number of the slave of the irrigation device, and the number is unique, and it is generally difficult for one irrigation network to reach ten thousand slaves, so that, generally, 9999 numbers are enough, slaves with the same number cannot be provided in the same network, otherwise, communication conflicts. Preferably, the numbering is not changeable, and the slave factory SN is already solidified inside and therefore not modifiable. The slave serial number is a fixed address of slave communication, and the equipment is solidified in a chip when being shipped. Without the concept of an interface, the numbered address is bound to the slave device. If the user clearly knows the number range of the slave device to be inquired, the address information range scanned by the slave device can be properly adjusted according to the corresponding range, so that the time for searching the slave device is reduced. The address information of the slave can be obtained according to the interface with the master, namely the number of the slave itself is not used as the address information, for example, for the interface No. 0001 of the master, the address information of the slave is determined to be No. 0001 No. no matter which slave is connected to the interface No. 0001, and the like.
In another embodiment of the present invention, the master defines the address information of the slaves according to the order in which the slaves feed back the master inquiry signals and the order in which the master receives the slave responses, that is, the slave that sends the response to the master first is defined as address information 0001, and so on.
In an embodiment of the present invention, also in step 101, the inquiry signal sent by the master to the slave refers to an inquiry packet, and the content of the inquiry packet includes address information of the target slave and inquiry information about whether the target slave exists. The master sends inquiry data packets to the possible slaves according to the address information, and sends inquiries to the corresponding slaves by using the content in the data packets.
In an embodiment of the present invention, in step 102, after the master sends the limited response time of the inquiry signal to the plurality of slaves, if the slave does not receive the response data packet sent from the slave, it is determined that the corresponding slave does not exist. The master machine is set with limited response time when receiving the response signal of the slave machine, under the normal condition, when the corresponding slave machine exists, the master machine sends an inquiry signal to the slave machine, the whole time length of the response signal of the slave machine is relatively fixed and is less than a certain time length, the time length is set as the limited response time, when the master machine sends the inquiry signal to the slave machine, and the response signal is not received after the response time is exceeded, the response time is abnormal, and the corresponding slave machine is judged to be absent.
In an embodiment of the present invention, in step 101-. When the host sends the recorded slave state information to the user side, the corresponding state information is also sent to the user side in addition to the existing slave address information.
In one embodiment of the present invention, in step 103, the master may send the corresponding status of the corresponding slave to the user side, but the status sent here is only "no fault", and when the master receives the fault information sent by the slave, the master records the slave number and the fault information, and sends only the slave address whose status is "no fault" to the user side, and the slave number and the status information that have fault are not sent to the user side.
In an embodiment of the present invention, in the steps 101-103, the steps are executed under specific conditions, specifically, after the slave access is completed, after the slave is newly added, after the slave is removed, and after the client request is received, the steps 101-103 are executed under the above four conditions.

Step 202: the plurality of slaves send responses to the interrogation signals to the master.
In the specific implementation of step 202, since the existing slave receives the inquiry signal sent by the master in the previous step, the slave needs to respond to the master.
In one embodiment of the present invention, in step 202, the response signal from the slave to the master includes sending a response packet to the master, where the response packet includes address information of the slave and response information of the slave.
In one embodiment of the present invention, in step 201, the inquiry signal received by the slave includes an inquiry packet, and the inquiry packet includes address information of the destination slave and inquiry information for inquiring whether the slave exists. After receiving the inquiry data packet, the slave analyzes the address information of the target slave in the data packet and verifies whether the address information of the target slave is matched with the address information of the slave, and if not, the slave does not respond to the inquiry signal. The inquiry data packet contains address information, each slave machine is bound with the address information, the slave machines analyze the inquiry data packet after receiving the inquiry data packet, firstly, the address information of the data packet and the address information of the slave machines are verified to see whether the two address information are matched, and the slave machines carry out response operation only when the two address information are matched with each other.
