In the description of the present application, it should be noted that the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.
The specific structural relationship of the communication control system and the included devices in the embodiment of the present application are specifically explained below.
Fig. 1 is a schematic structural diagram of a communication control system according to an embodiment of the present application, referring to fig. 1, the communication control system includes: a master control apparatus 100 and a plurality of sub-apparatuses 200; the main control equipment 100 is connected with each sub-equipment 200 through a bus, and the bus is used for communication connection between the main control equipment 100 and the sub-equipment 200; each sub-device 200 includes: a controller 210 and a switch assembly 220; the controller 210 is respectively connected with the switch assembly 220 and the bus 300, and is used for controlling the switch assembly 220 to be disconnected when the sub-device 200 is powered on for the first time, and sending an identity request signal to the main 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 slave device to the slave device 200 through the bus 300.
Optionally, the communication control system may specifically be a system for controlling a plurality of sub-devices through a master control device, and may specifically be applied to, for example, the irrigation field, where each sub-device may specifically be an irrigation device correspondingly disposed in a field of a certain area, for example, each sub-device may be controlled by one master control device in a bus manner.
The communication control system in the irrigation field shown above is only an example, and can be applied to any scenario meeting the control conditions in actual production and life, and is not limited thereto.
Alternatively, the master device 100 may specifically be any type of computer device, such as: computers, tablet computers, cell phones, special-purpose electronic devices, etc., are not particularly limited herein; the sub-device 200 may be any electronic device controlled by the main control device 100, or may be a computer, a tablet computer, a mobile phone, a special sub-device (e.g. an automatic irrigation device), etc.
Alternatively, bus 300 may be specifically any type of working bus, such as: RS485 bus, CAN (Controller Area Network ) bus, etc., without specific limitation herein. The master device 100 and each slave device 200 are connected by a bus, and the bus 300 is used for communication connection between the master device 100 and each slave device 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 bus, and the power supply is cut off while the communication is cut off.
It should be noted that, the power cut-off corresponds to the phase-change cut-off communication, and all belong to the scope of the method of the present application.

When the controller 210 is powered up, if the first power up is detected, the switch assembly 220 may be controlled to be disconnected.
It should be noted that, since the switch assemblies 220 of the plurality of sub-devices 200 are sequentially connected in series on the bus, when one of the switch assemblies 220 is disconnected, the communication between the sub-device at the subsequent 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 first power-on identity authentication of the sub-device, since the switch assemblies 220 of the sub-devices 200 are in a serial connection relationship, when each sub-device 200 is authenticated, the main control device 100 communicates with the first sub-device 200 through the communication bus 300, and the controller 210 determines whether the identity of the main control device 100 is an initial identity, if the identity is the initial identity, the sub-device can be determined to be powered on for the first time, and if the switch assemblies 220 are disconnected, the communication between other sub-devices and the main control device 100 is disconnected due to the serial connection relationship, and the controller 210 of the first sub-device can send an identity request signal to the main control device 100 through the bus, and the main control device 100 determines the identity of the sub-device based on the identity request signal and the currently allocated identity, for example: the initial identity of the sub-device is "0", the identity determined after the authentication of the first sub-device is "1", and after the authentication is completed, the master control device may send the identity to the controller 210 of the corresponding sub-device, where the controller of the sub-device may store the identity as a new identity (instead of the initial identity).
When authenticating the second sub-device 200, since the identity of the first sub-device is not already the initial identity, the controller 210 thereof determines that the first power-up is not performed, and the switch assembly 220 thereof is not disconnected; the second sub-device 200 repeatedly performs the foregoing authentication process, and during the authentication process, the master device 100 may determine the identity of the sub-device based on the identity request signal and the currently allocated identity, for example, may determine that the identity of the second sub-device is "2" (different from the initial identity and the authenticated identity, specifically may be set according to the actual requirement by increasing or decreasing the number, and the like, which is not limited herein). Accordingly, the master device may send the identity to the controller 210 of the corresponding slave device, which may store the identity as a new identity (instead of the initial identity).
The authentication process is repeated, so that the authentication of each piece of sub-equipment can be sequentially realized, and the process is the same as that described above and is not repeated here.

By utilizing the association relationship, information and the like of the sub-equipment associated with each land block can be timely obtained
Taking each piece of sub-equipment as an example, the identification of the piece of land is "land 1", "land 2" … … "land N"; the identity of the child device is "ID1", "ID2" … … "IDN".
