Description

Technical Field

[0001] The utility model belongs to the technical field of electric push rod control, in particular to an electric push rod cluster system with an automatic switching function. Background Art

[0002] The trunking system is a communication system used for group dispatching and commanding communications, and is mainly used in the field of professional communications. The available channels of this system can be shared by all users of the system, and it has the function of automatic channel selection. It has many advantages such as sharing resources, sharing costs, and sharing channel equipment and services.

[0003] For example, in an electric linear actuator cluster system, it includes N electric linear actuators, a central node and a networking controller. The controller sends networking instructions to the central node, and the central node is generally powered by the controller.

[0004] In the actual application of electric push rod clusters, it is found that if an electric push rod fails, it is relatively easy to replace it with a new one and then connect the new electric push rod to the network through the controller. However, once the central node fails, the entire system will be paralyzed, and the controller will not be able to perform any effective control on the push rods in the cluster. Usually, it is necessary to replace the central node at the site of use, and the electric push rods of all the child nodes need to be de-networked from the original network and then re-networked with the central node. This process is time-consuming and costly. Therefore, a technical means is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an electric push rod cluster system with an automatic switching function to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, a technical solution adopted by the utility model is: an electric push rod cluster system with automatic switching function, including a networking controller, a central node module, a backup central node module and an electric push rod;

[0007] The networking controller, the central node module and the electric push rod are in communication connection in sequence, the networking controller backup central node module and the electric push rod are in communication connection in sequence, and the networking controller includes a switching unit that switches the connection to the central node module or the backup central node module;

[0008] The central node module stores information about the electric push rod controlled by it;

[0009] The backup central node module includes a plurality of backup units, each of which corresponds to a central node module, and each of which stores information on the electric push rod of the central node module corresponding thereto.

[0010] Preferably, each of the electric push rods is communicatively connected to a central node module and a backup central node module.

[0011] Preferably, at least two of the electric push rods are communicatively connected to a central node module and a backup central node module.

[0012] Preferably, the communication method among the networking controller, the central node module, the backup central node module and the electric push rod includes any one of wireless communication or wired communication.

[0013] Preferably, the networking controller is powered on by a power supply to the central node module and the backup central node module, and the switching unit can cut off the power on between the networking controller and the central node module or the backup central node module.

[0014] Preferably, the networking controller further comprises an error reporting and restarting unit, and the error reporting and restarting unit is used to restart the faulty central node module to confirm whether the central node module can be reactivated.

[0015] The beneficial effects of the utility model are as follows: in the electric push rod cluster system applying the present solution, if a central node module abnormality occurs causing the electric push rod to fail to work normally, first, the error restart unit will restart the central node module to confirm whether the central node module can be enabled normally. If the central node module cannot be enabled normally, the switching unit will switch to the backup central node module, and the backup unit that backs up the central node module information in the backup central node module will start to ensure the normal operation of the electric push rod, thereby effectively ensuring work efficiency.

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] Example:

[0020] See also Figure 1 , an electric push rod cluster system with automatic switching function, including a networking controller, a central node module, a backup central node module and an electric push rod;

[0021] The networking controller, the central node module and the electric push rod are in communication connection in sequence, the networking controller backup central node module and the electric push rod are in communication connection in sequence, and the networking controller includes a switching unit that switches the connection to the central node module or the backup central node module;

[0022] The central node module stores information about the electric push rod controlled by it;

[0023] The backup central node module includes a plurality of backup units, each of which corresponds to a central node module, and each of which stores information on the electric push rod of the central node module corresponding thereto.

[0024] Each of the electric push rods is communicatively connected to a central node module and a backup central node module, wherein wireless communication may adopt Bluetooth, ZigBee, WiFi or other similar wireless technologies.

[0025] Among them, each central node module and each backup unit can communicate with one electric push rod, and each central node module and each backup unit can also communicate with two or more electric push rods.

[0026] The communication method among the networking controller, the central node module, the backup central node module and the electric push rod may be either wireless communication or wired communication.

[0028] Among them, the networking controller also includes an error reporting and restarting unit, which is used to restart the faulty central node module to confirm whether the central node module can be re-enabled. The error reporting and restarting unit can switch from the switching unit to the backup central node module if it is determined that the central node module cannot be enabled after multiple confirmations.

[0029] Working principle and process:

[0030] In the electric push rod cluster system applying the present solution, if a central node module abnormality occurs and causes the electric push rod to fail to work normally, first, the error restart unit will restart the central node module to confirm whether the central node module can be enabled normally. If the central node module cannot be enabled normally, the switching unit will switch to the backup central node module, and the backup unit that backs up the central node module information in the backup central node module will start to ensure the normal operation of the electric push rod. This saves time and effort and ensures work efficiency.
