Description

Technical Field

[0001] The present invention belongs to the technical field of liquid level measurement, and in particular relates to a wireless static level measurement system and method based on Internet of Things technology. Background Art

[0002] At present, all automatic static leveling systems are wired systems, that is, each device is connected in series with wires. Such equipment is easily damaged by lightning strikes and has extremely high maintenance costs, which seriously hinders the application and promotion of static leveling technology.

[0003] CN217845170U provides an automated settlement detection system, which points out that the GNSS solution is used to detect two static leveling sensors, a data acquisition gateway and a data processing unit; the data processing unit uses the real-time coordinates and elevation data received from the GNSS receiver as the reference data, and compares the settlement of each static leveling sensor, thereby calculating the settlement data of each monitoring point. This solution has low settlement monitoring accuracy, the GNSS solution cannot achieve sub-meter accuracy, and the GNSS+RTK can only achieve centimeter accuracy, which cannot meet the needs of settlement detection.

[0004] CN211205265U provides a constant temperature static level system including a static level and a gateway. The static level package controls the static level in a constant temperature manner, thereby improving the comprehensive measurement accuracy of the system around the clock. It does not propose how to transmit the relevant data of the level, and does not solve the problem of the level working in a harsh environment, which is prone to detection failure due to line reasons. Summary of the invention

[0005] In order to solve the problem of system instability caused by lightning strikes, unstable power grids and physical disconnection, the present invention provides a wireless static leveling measurement system based on Internet of Things technology. A single wireless static leveling device measures relevant static leveling data, and then multiple (no less than 256) wireless static leveling devices are connected together through a wireless chain network, and the measurement data is transmitted to the cloud platform through a wireless gateway, thereby avoiding the problem of system instability caused by lightning strikes, unstable power grids and physical disconnection. The wireless chain network of the present invention can be single-hop or multi-hop, and the abnormality of one device does not affect the overall signal acquisition, thereby improving the stability and anti-interference ability of the entire system.

[0026] Furthermore, the working process of the wireless static leveling device is as follows:

[0027] Step 1: After power-on, the system enters initialization, configures the working status of related modules, and then enters sleep mode. The wireless static level device wakes up at a scheduled time, or the wireless gateway sends a wake-up command to the wireless static level device to work;

[0028] Step 2: After the wireless static leveling device is awakened, determine whether the data exceeds the threshold;

[0036] When the base sinks, the liquid level in the storage tank changes. By detecting the pressure change of the wireless static level device at the base, the relative movement distance of the base is obtained through the pressure change.

[0039] The present invention is a wireless static level device. A single wireless static level device can perform wireless measurement without the need to arrange power and signal lines. Combined with a wireless detection system, it can meet application scenarios such as pre-installation, post-installation and later modification of equipment, reduce the difficulty of on-site deployment, improve system stability, and has low cost.

[0040] The present invention uses a single-hop or multi-hop wireless communication method in the form of a chain network to upload the collected angle data. The wireless chain network can realize long-distance data transmission. Through the relay of multiple nodes, the coverage of the wireless signal can be extended to a very far place. Compared with the traditional wired network, the wireless chain network has obvious advantages in construction cost. Laying long-distance cables or optical fibers requires a lot of manpower, material resources and financial resources, including the purchase of cables, the implementation of laying projects and the subsequent maintenance costs. However, the wireless chain network does not need to carry out large-scale cable laying, and only needs to install wireless node equipment, which greatly reduces the construction cost and construction difficulty. In practical applications, the flexibility of the wireless chain network is very high. If it is necessary to increase or decrease the nodes in the network, the operation is relatively simple. In some complex environments, the stability of the wireless chain network is excellent. Even if a node fails due to natural disasters, man-made damage and other reasons, as long as it is not a key node or multiple adjacent nodes fail at the same time, the network can continue to maintain a certain data transmission capacity by replanning the transmission path or enabling spare nodes, etc., to ensure the basic operation of the entire system.

The present invention uses a wireless transmission method of a chain network to transmit data in a single-hop and multi-hop manner. The wireless chain network is a special wireless network topology with a unique transmission method. In this network, each node is connected in sequence to form a chain-like shape. Data transmission usually adopts a relay method. The signal starts from the source node and is transmitted to the next adjacent node one by one in the form of wireless communication. Each node carries the data of the previous node until it reaches the target node, completing the transmission of all node data.

By detecting the pressure change of the wireless static level device 101 at the base 108, the relative movement distance of the base 108 is obtained through the pressure change, and then the original data is compared with the data of the base 108 to calculate the displacement of the base 108.
