Networked intelligent warehouse status detection control system

Abstract

The invention discloses a networked intelligent warehouse status detection control system, and the system comprises a network information layer, an on-site management layer, and an on-site control layer, which are divided into three standard industrial networks from the top to the bottom. The information layer comprises at least one remote computer. The on-site management layer comprises at least one on-site management and control computer and at least one on-site measurement and control host. The on-site control layer comprises at least one measurement and control extension set and terminal equipment or an instrument in communication with the measurement and control extension set. The remote computer is in communication connection with the on-site management and control computer through a network based on a TCP / IP network protocol. The on-site management and control computer is in wired or wireless communication connection with the measurement and control extension set through a USB or a WIFI or a network interface. The measurement and control extension set is in bus data connection or communication connection with the terminal equipment or instrument. The network architecture tends to flatness and standardization, thereby improving the system reliability.

Description

technical field [0001] The invention relates to storage condition detection technology in industries such as warehousing and logistics, in particular to a networked intelligent storage condition detection and control system. Background technique [0002] Taking the grain situation measurement and control system in the grain storage industry as an example, the network-based grain situation detection and control system in the prior art has the following characteristics: [0003] 1. Both remote operation and local operation are realized by connecting the computer with the measurement and control host; [0004] 2. The measurement and control extension and the field terminal equipment are connected through an expansion interface or some specific equipment such as a fault diagnostic device; [0005] 3. Multiple measurement and control extensions belong to a parallel structure, and the wireless communication path between each extension and the host is uniquely set; [0006] 4. Wh...

AI Technical Summary

Problems solved by technology

[0006] 4. When an extension node on the communication path fails, the communication path needs to be reset;

[0009] 7. The solar panel is only responsible for charging the battery, and the entire device and accessories are powered by the battery;

[0012] (1) The implementation of remote measurement and control is difficult, costly and unreliable;

[0013] (2) The remote microcomputer realizes remote measurement and control by connecting with the measurement and control host, and the host needs to have an interface such as the Internet, which is costly; the remote microcomputer also needs to install the corresponding software program to obtain or control the field equipment through the measurement and control host, which is troublesome to operate; multiple When the remote microcomputer communicates with the measurement and control host at the same time, there will be data command conflicts and other phenomena;

[0014] (3) There are many stages in the network structure and the efficiency is low:

[0015] From the measurement and control extension to the final on-site control equipment, it needs to go through the standard expansion interface, so that the communication rate is reduced and the failure rate is increased;

[0016] (4) The networking mode is not flexible:

[0017] The parallel connection method is adopted for the wireless communication of the measurement and control extension. The communication between the extension and the host must set a routing path. The rest of the associated devices will not be able to communicate, and the wireless communication path needs to be reset after replacing the device, which has poor flexibility;

[0018] (5) Poor environmental adaptability:

[0019] The entire power supply system only has solar panels and batteries. When some buildings cannot get enough sunlight and the battery capacity is limited, the power supply system will be paralyzed;

[0020] (6) Low energy utilization:

[0021] The power of the solar panel is generally about 0.5W. The glue drop board is prone to yellowing after 3 years of use, the light transmittance is low, and the conversion efficiency of solar energy is also low;

[0022] (7) Short service life:

Existing products still supply power to the system normally during this 98% time period, which causes a great waste of energy and relatively high power consumption
