Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a method and a device for automatically setting a communication address of a device. Background Art

[0002] With the development of computer and communication technology, the construction demand for data centers and base stations is also increasing, and their role in social and economic development is becoming increasingly prominent. Ensuring the normal power supply and uninterrupted operation of data center and base station equipment is one of the basic needs. Among them, the power distribution unit (PDU) used in data centers and base stations is used to distribute the required power to all equipment and is an indispensable infrastructure. In actual use, the operation and maintenance of data centers is becoming more and more sophisticated. As an important part of the data center, the PDU is becoming more and more intelligent. When managing PDU products, in order to save IP addresses and network port resources, physical connections are usually made in the form of master-slave machines. That is, there is a master device, which can be a PDU or a gateway connected to the network, and connected to the operation and maintenance management system through the network, and then connected to multiple PDU slave devices in a bus manner through this master device for cascade management. During the communication process, since different PDU slave devices are connected in bus mode, different address codes need to be set to facilitate communication between master and slave devices. The common address code setting is to manually configure the address one by one through hardware or software. This manual operation is very cumbersome and time-consuming, and it is easy to cause address confusion and errors, causing malfunctions and difficult to troubleshoot. Summary of the invention

[0003] The present invention provides a method and device for automatically setting the communication address of a device. In a single communication loop, the reliability and stability of the communication address setting can be ensured by executing a level pull-down operation and using an address control line, so that each plug-in box enters a communication address setting preparation state after receiving a low-level signal, avoiding the problems of address conflicts and configuration errors, and can automatically set the communication address, eliminating the tedious process of manual configuration, and improving the configuration efficiency and accuracy; at the same time, the configuration of the dual communication loop provides additional redundancy, enhances the system reliability, and thus provides users with more choices, with strong flexibility and a wide range of applications.

[0004] A method for automatically setting a device communication address, including communication address setting based on a single communication loop and communication address setting based on a dual communication loop; The communication address setting method of the single communication loop comprises: The main control module sets the communication address; The main control module performs a level pull-down operation through the communication port address control line, and transmits the level signal after the pull-down operation to the plug-in box, so that the plug-in box enters a communication address setting preparation state; The plug-in box receives and analyzes the communication address setting command sent by the main control module through the communication bus of the communication port, sets the communication address, and feeds back the communication address setting success information to the main control module; The plug-in box with the communication address set performs a level pull-down operation on the address control line connected to it, and the next plug-in box enters the communication address preparation state after recognizing the level signal of the previous plug-in box, and sets the communication address according to the communication address sent by the main control module; The operation is performed sequentially until the last plug-in box performs the level pull-down operation, and the level signal after the pull-down operation is transmitted to the main control module, thereby completing the communication address setting under the single communication loop; The communication address setting method of the dual communication loop comprises: Based on the first communication port, setting the communication address of the first communication loop; Based on the second communication port, setting the communication address of the second communication loop; The communication address setting of the first communication loop and the communication address setting of the second communication loop are completed in sequence to realize the universal address setting of the dual communication loops.

The communication address can be set automatically, eliminating the tedious process of manual configuration and improving configuration efficiency and accuracy. At the same time, the configuration of dual communication loops provides additional redundancy, enhances system reliability, and provides users with more choices, strong flexibility and a wide range of applications.

[0006] By further constructing, the main control module performs a level pull-down operation through the communication port address control line, transmits the level signal after the pull-down operation to the plug-in box, and makes the plug-in box enter a communication address setting preparation state, including: The main control module performs a level pull-down operation through the first communication port address control line, so that its output level signal is in a low level state; The head-end box receives the low-level signal output by the main control module, and transmits the low-level signal to the plug-in box through the address control line; The controller in the plug-in box detects and identifies the low-level signal, automatically adjusts to a receivable state, and puts the plug-in box into a communication address setting preparation state.

[0007] By executing the level pull-down operation, the output level signal is placed in a low level state.

[0011] By setting up independent communication ports and communication loops, data can be sent and received independently or simultaneously, thereby improving the access speed of the system and accelerating the real-time convergence of data between the plug-in box and the head-end box.

[0012] Furthermore, the first communication loop and the second communication loop share an address control line, and the address control line is controlled by the first communication port or the first communication port of the second communication port, and is used to automatically assign a communication address to the plug-in box.

[0016] Furthermore, the plug-in box is provided with an identity ID tag; the identity ID tag is consistent with the identity ID of the plug-in box.

[0017] Furthermore, an indicator light is provided on the plug-in box; the indicator light includes: A green indicator light, which is a power light; when the green indicator light is always on, it indicates that the power is connected; when the green indicator light is off, it indicates that the power is not connected; The yellow indicator light is a warning light. When the yellow indicator light flashes quickly, it indicates that the plug-in box has no identity ID. When the yellow indicator light flashes slowly, it indicates that the plug-in box has an identity ID but no communication address. When the yellow indicator light is always on, it indicates that the plug-in box has an identity ID and a communication address but there is an alarm. When the yellow indicator light is off, it indicates that the plug-in box has an identity ID and a communication address and there is no alarm. The red indicator light is a switch light; when the red indicator light is always on, it indicates that the switch is in a closed state; when the red indicator light is not on, it indicates that the switch is in an open state; there are multiple red indicator lights.

[0018] By setting indicator lights on the plug-in box, users can intuitively monitor the power connection of the plug-in box, whether there are alarms and the status of the switch, so as to timely discover and deal with potential problems, thereby reducing maintenance costs.

[0019] The beneficial effects of the present invention are: In a single communication loop, the present invention can ensure the reliability and stability of the communication address setting by executing a level pull-down operation and using an address control line, so that each plug-in box enters a communication address setting preparation state after receiving a low-level signal, avoiding address conflicts and configuration errors, and can automatically set the communication address, eliminating the tedious process of manual configuration, and improving configuration efficiency and accuracy; at the same time, the configuration of the dual communication loops provides additional redundancy, enhances system reliability, and thus provides users with more choices, with strong flexibility and a wide range of applications.
