Abstract
Description
Technical Field
[0001] The present invention belongs to the field of monitoring technology, and in particular relates to an autonomous communication interaction method and system for distributed logistics transmission equipment. Background Art
[0002] In the control process of transmission equipment, usually one controlled device corresponds to one logistics frequency converter. There are one or more PLCs in each logistics frequency converter, and no pre-processing module is set. As a result, when the on-site working conditions are complex, multiple logistics frequency converters are required. This requires multiple PLCs, which is costly. In addition, the various logistics frequency converters are unrelated during operation, which is not conducive to unified management. In addition, when attacking the PLC, it is easy to locate the PLC, causing excessive losses.

[0011] S6. The preprocessing module [Y1, Y2···Y n ] respectively pre-process the received data and forward it through the corresponding forwarding modules [Z1, Z2···Z n ] is transmitted to the main logistics frequency conversion integrated machine B a , through the main logistics frequency conversion integrated machine B a After unified data processing, corresponding control instructions are issued.
[0012] Furthermore, each logistics frequency conversion integrated machine has a unique number;
[0013] Each logistics frequency conversion integrated machine stores the number information of the n logistics frequency conversion integrated machines at the site.
[0014] Furthermore, the on-site staff handheld terminal stores the serial number information of each logistics frequency conversion integrated machine and the corresponding placement position information of each logistics frequency conversion integrated machine.
[0015] Furthermore, each logistics frequency conversion integrated machine is provided with a pre-processing module, a data acquisition module and a forwarding module.
[0016] Furthermore, the logistics frequency conversion integrated machine B b The corresponding preprocessing module is Y b , the corresponding data acquisition module is C b , the corresponding forwarding module is Z b , the corresponding controlled device is K b ;
[0017] Among them, 1≤b≤n.
[0018] Furthermore, the main logistics frequency conversion integrated machine B a The preprocessing module is Y a ; said Y a After the election process is completed, the Y aThe activation also requires the PLC to send an activation signal through the self-organizing network.
[0019] Furthermore, each logistics frequency conversion integrated machine collects the working parameters of the corresponding controlled equipment, specifically:
[0020] Each data acquisition module respectively acquires the operating parameters of the corresponding controlled device, and the operating parameters of the controlled device are: conveyor belt transmission speed, motor speed and whether there are goods on the conveyor belt.

After multiple logistics frequency conversion integrated machines are self-organized and networked, an election is conducted to select the main logistics frequency conversion integrated machine. PLC is only installed on the main logistics frequency conversion integrated machine. Other logistics frequency conversion integrated machines only have data collection, data forwarding, and data preprocessing functions. The pre-processed data of each logistics frequency conversion integrated machine is sent to the main logistics frequency conversion integrated machine. All data are processed by a PLC, and each controlled device is controlled based on the instructions corresponding to the preset working conditions. Except for the main logistics frequency conversion integrated machine, other logistics frequency conversion integrated machines only provide instruction forwarding function during the control instruction issuance process, which can effectively save PLC, save electricity, reduce production costs, and enable unified management of various devices.
[0028] 2. To reduce the workload of the PLC, a pre-processing module is set up in other logistics frequency converters except the main logistics frequency converter to perform preliminary data processing. The PLC can directly query the warning information and the existence of goods and make decisions on issuing instructions.
[0029] 3. After the main logistics frequency conversion integrated machine is determined through election and then deployed through the central control center, the PLC is manually installed and activated. This process can increase the randomness of the main logistics frequency conversion integrated machine, making it difficult for attackers to determine the location of the PLC, thereby increasing system security.
[0030] 4. During the networking process, any logistics frequency conversion integrated machine can initiate the networking process, and for any logistics frequency conversion integrated machine, it sends a networking request to the other n-1 logistics frequency conversion integrated machines, and receives the networking requests sent by the other n-1 logistics frequency conversion integrated machines except itself. All n logistics frequency conversion integrated machines simultaneously feedback the networking information of agreement to the other n-1 logistics frequency conversion integrated machines except themselves. The above method can ensure that the devices that access the network by broadcasting networking information are all logistics frequency conversion integrated machines required for networking; at the same time, the logistics frequency conversion integrated machine initiated by networking and the other n-1 logistics frequency conversion integrated machines are processed separately during the networking process, which can avoid signal conflicts during the networking process and facilitate monitoring of the networking process.
[0031] 5. Querying early warning information through PLC to trigger a click deceleration instruction can avoid malfunctions during transportation. At the same time, by confirming whether there is cargo on the controlled device to determine whether to stop the controlled device, it can save system resources. BRIEF DESCRIPTION OF THE DRAWINGS
