Background
In the field of irrigation, it is often necessary for a master to utilize communication to control slaves distributed throughout. The user side can issue instructions to the slaves with the designated numbers, so that the slaves can irrigate after receiving the instructions.
Communication between the master and the slave needs to be established first before the master takes control of the slave. It is necessary to add relevant slave address information to relevant user terminals, and then implement point-to-point communication between the master and each slave. Before adding the slave address, the master needs to know different slave addresses, and in a common scheme, the slave addresses need to be manually added one by one, however, the whole irrigation network is hung down by hundreds or thousands of slaves, so that adding numbers one by one from the user side manually is very troublesome.

In this embodiment, the primary operation performed by the master of the device includes a first step of sending an inquiry signal to a plurality of slaves to begin inquiring whether the corresponding slaves are present. And the second step is that the host receives the responses of the plurality of slaves to the inquiry signals, records the address information of the responded slaves, and after the inquiry signals sent by the host are responded by the slaves in the last step, the host receives the response signals, the received information contains the address information of the responding slaves, and the host also records the address information of the responding slaves when receiving the response signals. And thirdly, the host sends the recorded address signal of the replied slave to the user side, and in the step, the host executes a sending task and sends the address information of the slave to the client side. Finally, the automatic addition of the slave address information on the client is realized, so that the problem that the process of manually adding the slave to the host is excessively complicated is effectively solved.
Further, the master transmits an interrogation signal to the plurality of slaves, including: the host sequentially sends an inquiry data packet to each slave according to the slave address information; the interrogation data packet includes: address information of the destination slave, and inquiry information for inquiring whether the slave exists.
In the embodiment of the present application, the manner in which the master transmits the query packet to each slave has a certain order, specifically, the query packet is transmitted according to the address information sequence of the slave, and the slave is sequentially queried. The present embodiment details the specific contents of the data packet, and in addition to the address information, there is also an inquiry information for the purpose of conveying to the slave an inquiry as to whether the slave is present. In an alternative example, the address information of the slave includes the number of the slave, and the number of the slave is obtained when the slave leaves the factory.
In an alternative example, the number of the slave machine in the technical scheme of the application can adopt the SN number of the slave machine product or the last few bits of the SN number. In the embodiment, the number of the slave is unchanged, and when the slave equipment leaves the factory, the SN number is solidified in the slave, so that the number cannot be changed, the slave with the same number can be ensured to be absent under the same network, and the communication collision is avoided.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
Fig. 1 is a schematic diagram of steps performed by a method at a host side according to an embodiment of the present application, as shown in fig. 1, where the method includes:
step 101: the master transmits an interrogation signal to the plurality of slaves.
In the implementation of step 101, the master, as part of an irrigation device comprising a master and a plurality of slaves for irrigation implementation, performs a signaling function in this step, where the signaling may be one-to-one accurate signaling or one-to-many signaling at the same time, and the master may send interrogation signals to a plurality of possible slaves simultaneously in a certain order.
Step 102: the host receives the responses of the plurality of slaves to the inquiry signals and records the address information of the responded slaves.
In the implementation process of step 102, the host executes a receiving task, specifically, responses to signals sent by the slaves, where the signals are responses to the query signals sent by the slaves after receiving the query signals sent by the host in the previous step, and the response signals include address information of the relevant slaves that respond to the responses, and the host records the address information of the slaves while receiving the response signals.
Step 103: and the host sends the recorded address information of the replied slave to the user terminal.
In the implementation process of step 103, the host machine has received the response signal of the response slave machine and records the address information of the corresponding slave machine in the last step, in this step, the host machine needs to execute the sending task, the sending object of this step is the user end, and the host machine sends the response signal of the corresponding slave machine recorded in the last step to the user end.
In one embodiment of the present application, in the step 101, the master transmits an interrogation signal to the plurality of slaves, and during the transmission of the interrogation signal, the master transmits an interrogation packet to each of the slaves in order of the slave address information. The content of the inquiry data packet contains address information of the destination slave and inquiry information about whether the destination slave exists. The host transmits inquiry data packets to the possible slaves according to the address information, and uses the content in the data packets to transmit an inquiry to the corresponding slaves whether the slaves exist or not. The master may send signals to each possible slave one by one or in a random order, or may send signals one by one at the same time, where the signal sending has a certain order, and in the present application, the signals are sent in particular in the order of addresses of the slaves. The address information of the slave includes the number of the slave, and in this embodiment, the slave number can be used as one of the slave address information, and the specific corresponding slave can be easily obtained according to the number of the slave. In one embodiment of the application, the number of the slave is obtained at the time of leaving the factory of the slave, preferably the last four digits of the slave SN number of the irrigation device are unique, and one irrigation network is generally difficult to reach ten thousand slaves, so that 9999 numbers are enough in general, the slaves with the same number cannot be located under the same network, otherwise communication conflicts. Preferably, the number is not changeable, and the slave device factory SN is already cured inside and therefore cannot be changed. The slave number is the address fixed by the slave communication, and the device is solidified in the chip when leaving the factory. Without the concept of an interface, the numbering address is bound to the slave device. If the user clearly knows the range of the slave device numbers to be queried, the address information range scanned by the slave can be appropriately adjusted according to the corresponding range, so that the time for searching the slave is reduced. The address information of the slave can be obtained by its interface with the master, i.e., the number of the slave itself is not used as the address information, for example, for the 0001 number interface of the master, whichever slave is connected to this 0001 number interface, the address information of the slave thereof is determined to be 0001 number, and so on.
In another embodiment of the present application, the order in which the slaves feed back the master's interrogation signals, the order in which the slaves receive the slaves' replies, i.e. the first slave to send a reply to the master is defined as address information 0001, and so on.
In one embodiment of the present application, also in step 101, the interrogation signal sent from the master to the slave refers to an interrogation packet, where the content of the interrogation packet includes address information of the destination slave and interrogation information about whether the destination slave exists. The host transmits inquiry data packets to the possible slaves according to the address information, and uses the content in the data packets to transmit an inquiry to the corresponding slaves whether the slaves exist or not.
In one embodiment of the present application, in the step 102, after the master sends the inquiry signals to the plurality of slaves for a limited response time, the response data packet sent by the slave is still not received, and it is determined that the corresponding slave is not present. The host sets a limited response time when receiving the response signal of the slave, normally, when the corresponding slave exists, the whole time length from the transmission of the inquiry signal by the host to the reception of the response signal of the slave is relatively fixed and is lower than a certain time length, the time length is set to be limited to the response time, and when the host transmits the inquiry signal to a certain slave until the response signal is not received yet after the response time is exceeded, the host is abnormal, and the corresponding slave is judged to be absent.
In one embodiment of the present application, in the above steps 101-103, the master sends an inquiry signal to determine whether the corresponding slave is functioning properly in addition to whether the corresponding slave is present, so that the response signal received by the master also includes a status response to whether the slave is malfunctioning. When the host sends the recorded slave state information to the user terminal, the host sends corresponding state information to the user terminal in addition to the existing slave address information.
In one embodiment of the present application, in step 103, the host sends the corresponding state of the corresponding slave to the client, but the state sent here is only "no fault", when the host receives the fault information sent by the slave, the host records the slave number and the fault information, and only sends the slave address whose state is "no fault" to the client, and does not send the fault slave number and the state information to the client.
In one embodiment of the present application, in the steps 101-103, the steps 101-103 are performed under specific conditions, specifically, after the slave has completed access, after the new slave has been added, after the slave has been removed, and after the client request has been received.
Fig. 2 is a schematic diagram of steps performed by a slave-side method according to an embodiment of the present application, as shown in fig. 2, where the method includes:
step 201: the plurality of slaves receives the interrogation signals transmitted by the master.
In the implementation process of step 201, a plurality of slaves receive an interrogation signal sent from a master, and only the slaves that exist receive the interrogation signal sent from the master, it is obvious that if the corresponding slave does not exist, the corresponding slave cannot receive the interrogation signal sent from the master.
Step 202: the plurality of slaves sends a response to the interrogation signal to the master.
In the implementation of step 202, since the slave computer receives the inquiry signal sent by the host computer in the previous step, the slave computer needs to respond to the host computer, and in this step, sends a response signal to the host computer as a response to the host computer.
In one embodiment of the present application, in the 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 responding slave and response information of the slave.
In one embodiment of the present application, in the step 201, the interrogation signal received by the slave includes an interrogation packet, where the interrogation packet includes address information of the destination slave and interrogation information for querying whether the slave exists. After receiving the inquiry data packet, the slave analyzes the address information of the target slave in the data packet, verifies whether the address information of the target slave is matched with the address information of the slave, and does not respond to the inquiry signal if the address information of the target slave is not matched with the address information of the slave. The inquiry data packet contains address information, each slave machine also binds the address information, when the slave machine receives the inquiry data packet, the slave machine analyzes the inquiry data packet, firstly, the address information of the data packet is verified with the address information of the slave machine to see whether the two are matched, and only when the two address information are matched with each other, the slave machine can respond.
Fig. 3 is a schematic diagram of overall method execution steps according to an embodiment of the present application.
Step 301: the master transmits an interrogation signal to the plurality of slaves.
In the implementation of step 301, a master initiates a query of a plurality of slaves.
Step 302: the plurality of slaves receives the interrogation signals transmitted by the master.
In the implementation of step 302, if a corresponding slave exists, the corresponding slave receives the interrogation signal sent by the master.
Step 303: the plurality of slaves send a response to the interrogation signal to the master.
In the implementation process of step 303, when the slave has received the inquiry signal sent by the host in the previous step, the slave needs to respond to the host after receiving the inquiry signal, and the specific response form is that the slave sends a response signal to the host.
Step 304: the host receives the responses of the slaves to the inquiry signals and records the address information of the responded slaves.
In the implementation process of step 304, when the slave machine sends a response signal to the master machine in the previous step, the master machine needs to receive the response signal sent by the slave machine, and records address information corresponding to the slave machine sending the response signal while receiving the response signal.
Step 305: and the host sends the recorded address information of the replied slave to the user terminal.
In the implementation process of step 305, the host executes the sending task, and sends the slave address information recorded in the previous step to the client.
Fig. 4 is a schematic diagram of a host device according to an embodiment of the present application.
Referring to fig. 4, a host 400 is a host 400 applying for an irrigation device networking device. It should be understood that the host 400 may correspond to the embodiment of the method of fig. 1 described above, and is capable of executing the steps involved in the embodiment of the method of fig. 1, and specific functions of the host 400 may be referred to in the description of the related embodiments of the present application, and are omitted herein as appropriate to avoid repetition. In addition, the host 400 may perform different host-slave matching methods according to its modules without departing from the scope of the present application.
The host 400 includes: an interrogation module 401 for transmitting interrogation signals to the plurality of slaves. Under the action of module 401, the master sends an interrogation signal to multiple slaves, performing the task of initiating an interrogation. The present module performs a signaling function that is not a one-to-one accurate transmission, and module 401 will send interrogation signals to a plurality of possible slaves in a certain order.
A reply receiving module 402, configured to receive reply conditions of the plurality of slaves to the query signal and record address information of the replied slaves. The module 402 performs a receiving task, in particular a response to a signal sent by a plurality of slaves, which signal is a response to an interrogation signal sent by a slave after receiving the interrogation signal sent by the master in the previous step, referred to herein as a response signal, which response signal contains address information of the relevant slave in response to the response, and the module 402 records the address information of the slaves at the same time as the response signal is received.
An information sending module 403, configured to send the recorded replied slave address information to the user side. The host has received the response signal of the response slave and recorded the address information of the corresponding slave in the previous step, and in this step, the module 403 needs to perform a transmission task, and the transmission object of this step is the user terminal, and the module 403 transmits the response signal of the corresponding slave recorded in the previous step to the user terminal.
Optionally, in an embodiment of the present application, the query module 401 sends query signals to the plurality of slaves, and during sending of the query signals, the module 401 sends query packets to each of the slaves in order of slave address information. The content of the inquiry data packet contains address information of the destination slave and inquiry information about whether the destination slave exists. The module 401 sends an inquiry packet to the possible slaves according to the address information and uses the content in the packet to send an inquiry whether the corresponding slaves are present. The interrogation modules may send signals to each of the possible slaves one-to-one or in a random order, or may send signals one-to-many at the same time, with the signal sending having a certain order, in the present application, specifically in the order of the slaves' addresses.
Optionally, the address information of the slave includes the number of the slave, and in this embodiment, the slave number may be used as one of the slave address information, and the specific corresponding slave may be easily obtained according to the number of the slave.
Alternatively, the interrogation signal sent by module 401 to the slave refers to an interrogation packet, the contents of which include the address information of the destination slave and the interrogation information about whether the destination slave is present. The module 401 sends an inquiry packet to the possible slaves according to the address information and uses the content in the packet to send an inquiry whether the corresponding slaves are present.
Optionally, after the limited response time of the query signals sent by the module 402 to the plurality of slaves, no response data packet sent by the slaves is received yet, and it is determined that the corresponding slaves do not exist. The module 402 sets a limited response time when receiving the response signal of the slave, and normally, when the corresponding slave exists, the whole time period from when the slave module 401 transmits the inquiry signal to when the response signal of the slave is received is relatively fixed, and is lower than a certain time period, such time period is set to be limited to the response time, and when the module 401 transmits the inquiry signal to a certain slave until the response signal is not received after the response time is exceeded, the module 402 judges that the corresponding slave does not exist.
Optionally, the module 401 sends an inquiry signal to determine whether the corresponding slave is functioning properly in addition to determining whether the corresponding slave is present, and thus the response signal received by the module 402 also includes a status response to whether the slave is malfunctioning. When the module 403 sends the recorded slave status information to the client, the corresponding status information is also sent to the client in addition to the existing slave address information. The module 403 will send the corresponding state of the corresponding slave to the user terminal, but the state sent here is only "no fault", when the module 402 receives the fault information sent by the slave, the module 402 only records the number and the fault information of the slave, and only sends the address of the slave whose state is displayed as "no fault" to the user terminal, and the module 403 will not send the number and the state information of the slave with fault to the user terminal.
Optionally, the modules 401-403 may perform the above functions only in the four cases after the slave has completed access, after the slave has been newly added, after the slave has been removed, and after receiving the client request.

It should be understood that, corresponding to the above embodiment of the method of fig. 2, the slave 500 is capable of executing the steps involved in the embodiment of the method of fig. 2, and specific functions of the slave 500 may be referred to in the description of the related embodiments of the present application above, and are omitted here as appropriate to avoid repetition. In addition, the slave 500 may perform different master-slave matching methods according to its modules without departing from the scope of the present application.
The slave 500 includes: an interrogation receiving module 501 for receiving an interrogation signal sent by the host. The query receiving module 501 receives the query signal sent from the host, and only the modules 501 of the slave that are present receive the query signal sent from the host, and it is obvious that if the corresponding slave is not present, the corresponding modules 501 cannot receive the query signal sent from the host.
A reply module 502 for sending a reply to the interrogation signal to the host. Since the slave corresponding module 501 receives the inquiry signal sent by the host, it needs to answer the host, and in this step, the module 502 sends an answer signal to the host as an answer to the host.
Optionally, the module 502 sends a reply packet to the host, where the reply packet includes address information of the reply slave and reply information of the slave.
Optionally, the interrogation signal received by module 501 includes an interrogation packet that includes address information of the destination slave and interrogation information that interrogates whether the slave is present. After receiving the query packet, the module 501 parses the address information of the destination slave in the packet, verifies whether the address information of the destination slave matches with the address information of the destination slave, and if not, the module 502 does not respond to the query signal. The query packet includes address information, and each slave machine also binds the address information, and when the module 501 receives the query packet and then analyzes the query packet, the module 502 first verifies the address information of the packet and the address information of the slave machine to see whether the two match, and only when the two address information match with each other, the module 502 performs a response operation.
