Technical Field

[0001] The present application relates to the field of Internet of Things control, and in particular to a device power control system and method based on MODBUS. Background Art

[0002] The MODBUS network is an industrial communication system, which is composed of programmable controllers with intelligent terminals and computers connected through public lines or local dedicated lines. Its system structure includes both hardware and software. Through this protocol, controllers can communicate with each other and with other devices via a network (such as Ethernet). It has now become a universal industrial standard. By building a MODBUS network, control devices produced by different manufacturers can be connected into an industrial network for centralized monitoring.

[0003] However, existing IoT control systems are generally complex, with cumbersome configuration and operation, which is not conducive to installation, deployment and maintenance. Most of them are B / S architectures and rely on WEB services, which not only have high delays and costs, but also make it difficult to achieve cross-platform operations. Summary of the invention

[0006] Furthermore, the client host is bound to part of the MODBUS server.

[0007] Furthermore, the central control server obtains the status information of the MODBUS server by periodically polling the MODBUS server, and registers with the central control server.

[0008] Furthermore, the client host periodically transmits status information of the client host to the central control server and registers with the central control server.

[0009] Furthermore, when the control terminal executes the instruction, the central control server is used to query the status information of the MODBUS server, and the Internet of Things intelligent switch group is controlled by sending instructions to the online MODBUS server.

[0010] Furthermore, controlling the IoT intelligent switch group by sending instructions to the online MODBUS server includes: performing cluster control on the IoT intelligent switch group corresponding to the MODBUS server, or individually controlling switches of the IoT intelligent switch group.

[0011] Furthermore, when the instruction is a shutdown instruction, it also includes: if the MODBUS server is bound to the client host, the shutdown operation of the client host is first triggered, and after a predetermined time, it is determined whether the client host is shut down; if the client host is shut down, the IoT smart switch group is controlled to shut down.

[0012] Furthermore, after determining whether the client host is shut down after a predetermined time, the method further includes: if the host device is not shut down, stopping the shut down instruction and performing problem troubleshooting.

[0013] According to one aspect of the present application, a device power control method based on MODBUS is also proposed. The method is implemented by the device power control system based on MODBUS described above, and includes the following steps:

[0014] Configuring the device information in the device database;

[0018] Furthermore, the control terminal controls the IoT intelligent switch group through the central control server and the MODBUS server, including:

[0019] The control terminal executes an opening instruction, uses the central control server to query the status information of the MODBUS server, and controls the IoT intelligent switch group by sending an opening instruction to the online MODBUS server;

[0020] The control terminal executes the shutdown command and uses the central control server to query the status information of the MODBUS server. If the MODBUS server is bound to the client host, the shutdown operation of the client host is triggered first, and it is determined whether the client host is shut down after a predetermined time. If the client host is shut down, the IoT smart switch group is controlled to shut down; if the host device is not shut down, the shutdown command is stopped and the problem is checked.

[0032] Example 1

[0033] Figure 1 The system block diagram of the device power management system based on MODBUS according to an embodiment of the present application is shown. Figure 1 The system includes: a central control server 100, a MODBUS server 200, an IoT intelligent switch group 300, a control terminal 400, a device database 500 and a client host 600. The various parts of the system are connected through network protocol communication.

[0034] Specifically, see Figure 2, Figure 2 The following is a schematic diagram of the module-based flow of a device power management system based on MODBUS according to an embodiment of the present application. The various parts of the system can be connected by wire and communicated through a network protocol, and communicate through the central control server 100. Different from the B / S architecture, the system does not need to rely on WEB services, so that cross-platform operation can be achieved.

[0035] The central control server 100 is used to connect various parts of the system for communication. Specifically, the central control server 100 is connected to the MODBUS server 200, the control terminal 400, the device database 500, and the client host 600 through the network protocol, and is responsible for the communication of each part. The central control server 100 will periodically poll the MODBUS server 200 to obtain the status information of the MODBUS server 200, including online information, and whether it is bound to the client host, and register in the central control server 100.

[0036] The central control server 100 can be run in a computer host or in a platform system, and the network can use LAN or WAN as a transmission endpoint, which is not specifically limited here.

[0037] The MODBUS server 200 is used to control the IoT smart switch group 300 according to the instructions of the control terminal 400. Specifically, there may be one or more MODBUS servers 200, and each MODBUS server 200 corresponds to an IoT smart switch group 300. Through the MODBUS server, devices produced by different manufacturers can be compatible, and each IoT smart switch group can communicate with the central control server 100 through the corresponding MODBUS server, thereby building an industrial network for centralized monitoring.

[0038] The IoT smart switch group 300 is used to control the device and realize the device power management. By controlling the power on and off of the IoT device, the IoT device can be turned on and off, and the IoT device can be turned on and off. Specifically, the IoT smart switch group 300 can be one or more. By dividing different IoT smart switch groups, cluster control of devices can be realized, and devices in the cluster can also be controlled individually, taking into account both efficiency and flexibility.

[0039] The control terminal 400 is used to send instructions to control the device. Specifically, the following steps are included:

[0040] The control terminal 400 first obtains the status of the central control server 100 by communicating with the central control server 100, and determines whether the central control server 100 is online. If it is not online, it is displayed as offline. If it is online, the next step is performed.

[0041] The control terminal 400 queries and displays the device information through the central control server 100, and the central control server 100 obtains the device information transmission through the device database 500.

[0042] When the control terminal 400 sends an opening instruction, the control terminal 400 queries the status of the MODBUS server 200 through the central control server 100, and if it is not online, it is marked as offline; if it is online, it sends an opening instruction to the MODBUS server 200, and MODBUS controls the corresponding IoT smart switch group according to the instruction, thereby realizing the opening operation of the device power supply.

[0043] When the control terminal 400 sends a shutdown command, the control terminal 400 queries the status of the MODBUS server 200 through the central control server 100, and if it is not online, it is marked as offline; if it is online, it determines whether the MODBUS device is bound to the client host 600. If bound, the client host 600 is first shut down, and a shutdown command is sent to the client host 600. After the predetermined time arrives, it determines whether the client host 600 is shut down successfully. If it is shut down successfully, a shutdown command is sent to the MODBUS server 200. MODBUS controls the corresponding IoT smart switch group according to the command, thereby realizing the power off operation of the device, that is, shutting down the corresponding IoT device; if the shutdown fails, the shutdown command is stopped and the fault is checked.

[0044] Through the above steps, the power supply of the device can be controlled, and the properties of offline detection and fault detection can be achieved.

[0045] The device database 500 is used to configure device information. Specifically, the device information includes the device type and the device ownership. The device database contains information about all devices, including the central control server, the MODBUS server, the client host, the control terminal, and the IoT intelligent switch group. Each IoT intelligent switch group will contain control switches for multiple different IoT components, and the IoT components and devices in the IoT intelligent switch group can be opened and closed through the MODBUS server. Each device can be connected through a communication line and can communicate through the modbus communication protocol. After configuring the device information, the device database 500 is connected to the central control server 100 through the network, and the central control server 100 can query in the device database 500 to provide device information to the control terminal 400. This makes it easier for the operator to view the device status and manage the device. Among them, the client host of this system refers to the corresponding IoT intelligent switch group and the IoT device corresponding to the IoT intelligent switch group, which is equipped by the manufacturer or the corresponding service host. When controlling in this system, the client host corresponding to the corresponding IoT device is first turned off, and then the power is disconnected through the MODBUS server. Ensure the normal operation of the client host corresponding to the IoT device.

[0046] The client host 600 is used to record device information and transmit the status information of the client host 600 to the central control server 100. Specifically, the client host 600 will periodically transmit the status information of the client host 600 to the central control server 100, including heartbeat information, to determine the online status and connection status of the client host, and register with the central control server 100. The client host 600 is bound to some MODBUS servers 200, so as to record device information during device operation and realize safety monitoring.

[0051] Step 1100, configure device information in the device database.

[0052] Step 1200: The central control server periodically polls the status information of the MODBUS server and registers on the central control server. In this step, when the MODBUS server is connected to the entire control system, it can first register on the central control server. When the central control server controls the IoT smart switch group, it controls the IoT smart switch group through the MODBUS server.

[0053] Step 1300: The client host periodically transmits the client host status information to the central control server and registers with the central control server. In this step, each client host can register with the central control server before accessing the entire control system. When the central control server controls the IoT smart switch group, it will query whether there is a registered client host, and if there is a registered host, it will control the client host first, and then control the IoT smart switch group through the MODBUS server.
