The specific structural relationship of the communication control system in the embodiment of the present application and the included devices are specifically explained below.
Fig. 1 is a schematic structural diagram of a communication control system according to an embodiment of the present application, and referring to fig. 1, the communication control system includes: a master device 100 and a plurality of child devices 200; the main control device 100 is connected with each sub-device 200 through a bus, and the bus is used for communication connection between the main control device 100 and the sub-devices 200; each child device 200 includes: a controller 210 and a switch assembly 220; the controller 210 is respectively connected to the switch component 220 and the bus 300, and is configured to control the switch component 220 to be disconnected when the child device 200 is powered on for the first time, and send an identity request signal to the master control device 100 through the bus 300; the switch assemblies 220 of the sub-devices 200 are sequentially connected in series; the master device 100 receives the identity request signal through the bus 300 and transmits the identity of the child device to the child device 200 through the bus 300.
Optionally, the communication control system may specifically be a system that controls a plurality of sub-devices through the main control device, and may specifically be applied to the field of irrigation, for example, each sub-device may be controlled by one main control device in a bus manner, and each sub-device may specifically be an irrigation device and the like correspondingly disposed in a field in a certain area.
The communication control system in the irrigation field shown above is only an example, and may be applied to any scene meeting the control condition in the actual production life, and is not limited thereto.
Optionally, the master control device 100 may specifically be any type of computer device, such as: a computer, a tablet computer, a mobile phone, a dedicated electronic device, etc., which are not specifically limited herein; the sub-device 200 may be any electronic device controlled by the main control device 100, and may also be a computer, a tablet computer, a mobile phone, a special sub-device (such as an automatic irrigation device), and the like.
Alternatively, the bus 300 may specifically be any type of working bus, such as: RS485 bus, CAN (Controller Area Network) bus, etc., and is not particularly limited herein. The master device 100 and each of the child devices 200 are connected by a bus, and the bus 300 is used for communication connection between the master device 100 and the child devices 200.
Alternatively, the bus 300 may be a power bus in power carrier communication, that is, the power supply and the communication are the same set of bus, and the power supply is cut off while the communication is cut off.
It should be noted that the method of the present application is intended to cut off the power supply, which corresponds to phase change cut-off communication.
Optionally, the controller body 210 in the sub-device 200 may be an MCU (micro controller Unit), and the switch component 220 may be a switch for controlling connection to be turned off, and the switch component is kept in a normally closed state in an initial state, so that when one of the sub-devices is abnormal, access to the bus of the other sub-devices is not affected. When the controller 210 is powered on, if it is detected as being powered on for the first time, the switch assembly 220 may be controlled to be disconnected.
It should be noted that, because the switch elements 220 of the sub-devices 200 are sequentially connected in series on the bus, when one of the switch elements 220 is turned off, the communication between the sub-device at the later stage and the main control device is disconnected.
When identity authentication is performed, the specific authentication process is as follows:
in the process of performing the identity authentication of the first power-on of the sub-devices, because the switch components 220 of the sub-devices 200 are in a serial relationship, when each sub-device 200 is authenticated, the sub-devices 200 are sequentially authenticated, when the first sub-device 200 is authenticated, the main control device 100 communicates with the first sub-device 200 through the communication bus 300, the controller 210 determines whether the identity of the main control device is an initial identity, if the initial identity is the first sub-device, it can be determined that the sub-device is powered on for the first time, the switch components 220 can be controlled to be turned off, after the switch components 220 are turned off, due to the serial relationship, the communication between the other sub-devices and the main control device 100 is turned off, the controller 210 of the first sub-device can send an identity request signal to the main control device 100 through the bus, the main control device 100 determines the identity of the sub-device based on the identity request signal and the currently assigned identity, for example: the initial identity of the sub-device is "0", the identity determined after the first sub-device is authenticated is "1", after the authentication is completed, the main control device may send the identity to the controller 210 of the corresponding sub-device, and the controller of the sub-device may store the identity as a new identity (replacing the initial identity).
When the second sub-device 200 is authenticated, since the identity of the first sub-device is not the initial identity, the controller 210 determines that the first sub-device is not powered on for the first time, and the switch component 220 is not turned off; the second sub-device 200 repeatedly performs the foregoing identity authentication process, and during the authentication process of the main control device 100, the identity of the sub-device may be determined based on the identity request signal and the currently assigned identity, for example, the identity of the second sub-device may be determined to be "2" (different from the initial identity and the authenticated identity, specifically, the setting may be performed according to a digital increment or decrement according to an actual requirement, which is not limited herein). Accordingly, the master device may send the identity to the controller 210 of the corresponding sub-device, and the controller of the sub-device may store the identity as a new identity (instead of the original identity).
The authentication process is repeated to sequentially implement the authentication of each sub-device, and the process is the same as the above process, which is not repeated herein.
In a communication control system provided in an embodiment of the present application, a master control device is connected to each of sub-devices through a bus, and the bus is used for communication connection between the master control device and the sub-devices; each sub-device comprises: a controller and a switch assembly; the controller is respectively connected with the switch assembly and the bus, and is used for controlling the switch assembly to be disconnected when the sub-equipment is powered on for the first time and sending an identity request signal to the main control equipment through the bus; the switch components of each sub-device are sequentially connected in series; the master control equipment receives the identity request signal through the bus and sends the identity of the sub-equipment to the sub-equipment through the bus. The bus is sequentially connected with the switch assemblies of the sub-devices in series, so that the corresponding identity can be sequentially determined for each sub-device when the sub-devices are powered on for the first time, the identity corresponding to each sub-device can be recorded on the main control device, and accordingly, the efficiency and accuracy of identity configuration can be improved.
The following specifically explains a specific structural relationship of the switch assembly in the communication control system provided in the embodiment of the present application.
Fig. 2 is a schematic structural diagram of a communication control system according to an embodiment of the present application, and referring to fig. 2, a switch element 220 includes: a switch 221 and a driving unit 222; the switch 221 is connected with the driving unit 222, and the driving unit 222 is connected with the controller 210; the controller 210 is configured to send a level signal to the driving unit 222 when the sub-device 200 is powered on for the first time; the driving unit 222 is used for controlling the switch 221 to disconnect according to the level signal.

Optionally, the switch assembly 220 may further include: one end of the pull-down resistor 223 is connected to the driving unit 222, and the other end of the pull-down resistor is grounded, specifically, the pull-down resistor may be a 10K Ω resistor, when the controller 210 is not powered, the driving unit 222 may be pulled down, so that the driving unit 222 controls the switch 221 to be kept closed, wherein the switch 221 is an analog switch or a normally closed relay, and when the switch 221 is a normally closed relay, if a sub-device of a certain node is damaged, the switch 221 may still be kept in a closed state, so that communication of a rear-stage sub-device is prevented from being cut off.
Optionally, the identity of the sub-device is associated with one or more plots.
Taking field irrigation as an example, in a field irrigation system, there may be a plurality of plots, each sub-device is used for irrigating one or more of the plots, and each plot may be provided with a plot identifier.
For example: an identifier can be set for each land, and the identifier of each land and the identity of the corresponding sub-equipment for irrigation are associated.
By utilizing the incidence relation, the information and the like of the sub-equipment associated with each region can be obtained in time
For example, each sub-device is associated with a parcel, the parcel is identified as "parcel 1", "parcel 2" … … "parcel N"; the identities of the kid devices are "ID 1", "ID 2" … … "IDN". Then "parcel 1" may be associated with "ID 1," parcel 2 "may be associated with" ID2, "parcel N" may be associated with "IDN.
The above is only one possible example, and not intended to be limiting.
The following specifically explains a specific implementation procedure of the identity determination method of the communication control system provided in the embodiment of the present application.

The switch assemblies of the sub-devices can be sequentially connected in series through the bus, so that the corresponding identification can be sequentially determined for each sub-device when the sub-devices are powered on for the first time, the identification corresponding to each sub-device can be recorded on the main control device, and accordingly timeliness and accuracy of identification determination for each sub-device can be improved.
Optionally, when the sub-device is powered on for the first time, controlling the switch assembly to be turned off includes: when the sub-device is powered on for the first time, a level signal is sent to the driving unit, so that the driving unit controls the switch to be switched off based on the level signal.

Optionally, before the control switch works, it may be determined whether the current power-on is the initial power-on, since the controller may update according to the identity sent by the main control device after the initial power-on, the identity of the current sub-device may be detected during power-on, and if the current identity is the initial identity, the sub-device is determined to be the initial power-on; if the identity is not the initial identity, it can be determined that the sub-device has been powered on, and a subsequent identity determination process is not required.
The following specifically explains a specific implementation procedure of the identity assignment method of the communication control system provided in the embodiment of the present application.
Fig. 4 is a flowchart illustrating an identity allocation method of a communication control system according to an embodiment of the present application, please refer to fig. 4, where the method is applied to a master control device, and the method includes:

Optionally, generating an identity for the target sub-device based on the identity request signal and the currently assigned identity, including: and based on the identity request signal, adding one to the currently allocated identity to obtain the identity of the target sub-equipment.
For example, an initial identity may be set to "0", and if the currently allocated identities are 0, the identity of the child device from which the identity request signal originates may be determined to be "1" based on the identity request signal; accordingly, if there are 10 currently assigned ids, the id of the source sub-device of the id request signal may be determined to be "11" based on the id request signal.
Optionally, the foregoing allocation manner is only an example, and in an actual implementation process, a determination order of each identity may be set according to an actual requirement, for example: increasing, decreasing, or other permutation order, etc., without limitation.
Optionally, after adding one to the currently allocated identity based on the identity request signal to obtain the identity of the target sub-device, the method further includes: and taking the identity of the target sub-device as a new currently allocated identity.
Optionally, after each id of one sub-device is determined, the currently allocated id stored in the master device may be updated, for example: after the sub-device with the identity identifier of "2" is determined, the currently allocated identity identifier may be updated to "2", and when the identity identifier of the next sub-device is determined, one may be added directly on the basis of the updated currently allocated identity identifier to complete the determination process.
In the identity allocation method of the communication control system provided by the embodiment of the application, a current identity request signal sent by a target sub-device can be received; generating an identity for the target sub-device based on the identity request signal and the currently allocated identity; and sending the identity to the target sub-equipment. The switch assemblies of the sub-devices can be sequentially connected in series through the bus, so that the corresponding identification can be sequentially determined for each sub-device when the sub-devices are powered on for the first time, the identification corresponding to each sub-device can be recorded on the main control device, and accordingly timeliness and accuracy of identification determination for each sub-device can be improved.

In the process of allocating the identity of the sub-device by the main control device, the association relationship between the target sub-device and the target parcel can be established.
For example: in a farmland irrigation system, each sub-device corresponds to one or more target plots, the sub-device is used for carrying out irrigation and other work on the corresponding target plots, and after an identity is distributed to a first sub-device, the plot identification of the target plot corresponding to the first sub-device can be determined, so that the plot identification of the target plot corresponding to the identity of each sub-device can be determined, and the corresponding incidence relation is established and stored.
The main control device (or other electronic devices connected to the main control device) may determine the target parcel corresponding to each sub-device based on the association relationship, and when the user queries information of the sub-device based on the main control device, the main control device may provide information of the target parcel corresponding to each sub-device, where the information of the target parcel may be pre-stored in the main control device, and may be called and acquired after determining a parcel identifier of the target parcel.
Optionally, the main control device may be in communication connection with a mobile terminal, where the mobile terminal may be a mobile phone or other electronic devices, an application program may be set in the mobile terminal, and a user may operate the application program, for example: the mobile terminal can respond to the query of the user to the target sub-device, and can acquire the identity of the target sub-device and the parcel information of the target parcel corresponding to the target sub-device through the main control device.
In practical applications, based on the association relationship pre-stored in the main control device, the target parcel may also be queried through the mobile terminal, so as to determine the target sub-device corresponding to the target parcel, and the like, which is not limited herein.
According to the identity distribution method of the communication control system, the incidence relation between the target sub-equipment and the target plot can be established and stored based on the identity of the target sub-equipment and the identity of each plot, so that a user can conveniently obtain the information of each sub-equipment and the information of the plot corresponding to each sub-equipment in time, and the working efficiency of the farmland irrigation system is improved.
