Intelligent networking of measurement and control technology

Avior's devices can run in a real-time synchronous network. There can be two types of devices in this network: active and passive. The active device provides information to the network and reads the information in the network. Each active device has a separate network address. The difference between passive devices is that they can not provide information to the network, but can only read the data needed for work. The total number of all devices shall not exceed 256. All devices are the same, and the type of interaction in the network - active or passive - is determined in the preconfigured phase alone or as part of the configured network. Special software is used to record and configure equipment. The state of each active device that is part of the network is the same as that of other active devices that are also part of the network. There are no leading and leading devices. If any active device is turned off, the network will not lose its health and continue to operate as long as there is at least one active device on the network. The passive device, because it will not affect the function and logic of the network, executes the required working algorithm, and uses the information from the active device required for this work. Shows one of the network and device options. The active equipment is marked in blue and the passive equipment is marked in white.

The speed of the network depends on the number of active devices and the frequency of data transmission, and software is also configured. Both active and passive devices can perform control and display functions, and copy and manage devices that are online. Any device can be connected, disabled and replaced during the network period without affecting the health and functions of the network.

Logic behind the network:

The active device organizes and manages the network. Each device has a separate network address, which is allocated in the network configuration phase. The device with the lowest network address always starts transmission, so even if the network disables the device that starts switching for some reason, its function will move to the next high-level address device. Therefore, as long as there are active devices and working in the network, the switching on the network will continue. The data packets directly follow one another. For example (the number indicates the address of the active device): 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 0 - 2 - 3 -... Once the previous device completes the transmission of the required data packets, the next device starts to transfer the following contents to the qualification. If a continuous sequence of devices is interrupted, such as deleting a device from the network or an interrupt (for example, 0 - 0 - 2 - 3 - 4 - 6 - 7 - 9 -...), a packet with a device address of address 5 will be transferred to the device site of address 5. In this case, the entire network switching cycle will be shortened by the Dina of the device packet transmission at address 5. If a new device is added to the network, it will automatically register on the network, and the switching cycle will be extended to the length of the newly added device package. When the network works through the corresponding branch, any device may be added or deleted. The complete network switching cycle is based on the premise that the invulnerability of the equipment remains unchanged. This is the whole network is indestructible. There is no concept of leading and leading devices. Each data set is composed of three parts, including title, data set and control quantity. The data block cannot exceed 251 bytes in the current version of the network protocol.

Passive devices do not organize networks. If any passive devices are added or deleted, the network cycle and informational content will not be interrupted. The passive device may perform management functions by reading required information from the network, accumulating and registering data, and managing the network. If necessary, the active device can also perform network management. The master synchronization flag is the length of time required in the network. In any network conflict, all devices will be automatically disconnected and put into standby state by the timed out synchronization network. After that, the network will automatically reopen. If necessary, the network can organize local management and data collection in real time, and has high network reliability. If you need to transfer the whole or part of the data set to a remote server or remote management network, you can perform this function across a bridge, which is organized by a passive device to almost any configured external network.
