Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment and industrial equipment, and in particular relates to a high-reliability mining intrinsically safe wireless inclination sensor system and a use method thereof. Background Art

[0002] Inclination sensors are mainly used in the field of mines and mining, including underground mines, open-pit mines, ports, grain depots, and factories. Inclination sensors are used to detect the posture and tilt of equipment. They play an important role in hydraulic support monitoring, support posture control, rock formation detection, and monitoring of the tilt angle, posture, and working status of equipment. However, most of the existing inclination sensors are wired and have high cost. At the same time, in actual applications, the on-site environment is harsh and requires a higher level of waterproof and dustproof. There are even extreme situations such as flooding, high-pressure water guns, collisions and burials on site. Actual application needs put forward higher requirements for high-reliability inclination sensors. At the same time, in the process of production, testing, and actual application, it is also found that the reliability of single sensor and controller solutions is low. When the sensor is subjected to stress, the chip will be virtual and peeled off, resulting in abnormal working status of the sensor. Summary of the invention

[0003] In view of the problems of low reliability, poor stability and high cost of existing sensors during use, the present invention provides a high-reliability intrinsically safe wireless inclination sensor system for mining and a method for using the system.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A high-reliability intrinsically safe wireless inclination sensor system for mining, the system comprising a high-reliability wireless sensor device, a wireless gateway, and a cloud platform;

[0006] The wireless gateway is wirelessly connected to the high-reliability wireless sensor device and the cloud platform respectively;

[0007] The wireless gateway is used to receive the sensing data of the high-reliability wireless sensor device or send a wake-up instruction to the high-reliability wireless sensor device;

[0008] The high-reliability wireless sensor device periodically sends or receives a wake-up signal from the wireless gateway and then sends data. The high-reliability wireless sensor device collects current angle data according to the timed wake-up instruction of the wireless gateway, and uploads the collected angle data to the wireless gateway in a chain network using a single-hop or multi-hop wireless communication method; a single-hop is a wireless communication transmission performed by two adjacent high-reliability wireless sensor devices in relay; a multi-hop is a wireless communication transmission performed by one or more high-reliability wireless sensor devices in relay;

[0009] The cloud platform conducts comprehensive analysis and judgment on the angle data uploaded by the wireless gateway.

[0010] Further, the high reliability wireless sensor device includes a main system, one or more backup systems, a battery, a wireless transmission circuit and a housing;

[0011] The main system includes a main controller, a main sensor, and a main antenna;

[0012] The backup system includes a backup controller, a backup sensor, and a backup antenna;

[0017] Furthermore, the high-reliability wireless sensor device or wireless gateway is disposed in a housing, the housing is sealed with epoxy resin and meets the IP65 protection grade;

[0018] The wireless transmission circuit of the high-reliability wireless sensor device or wireless gateway adopts a circuit board microstrip antenna and is connected to the respective main controllers through a feeder line.

[0019] Furthermore, the main controller and the backup controller are both wireless communication units with MCU functions; and the main sensor and the backup sensor are both angle sensors.

[0020] Furthermore, the main system and the backup system of the high-reliability wireless sensor device adopt dual-machine hot standby, and when a failure occurs in the main system, the system switches to the backup system to work.

[0021] Furthermore, the main controller in the high-reliability wireless sensor device collects angle data of the main sensor and the backup sensor respectively, analyzes and calculates the data, and synchronizes and communicates data with the backup controller; after the main controller works normally and successfully sends the sensor data, it sends a synchronization signal to the backup controller 202, and the backup controller enters a sleep mode or a non-actual function mode;

[0022] When the main controller fails to collect data from the main sensor via SPI or I2C, it switches to the backup sensor to collect data via SPI or I2C;

[0023] After the main controller transmits abnormally, it synchronizes with the standby controller via SPI or UART. When there is no synchronization signal, the standby controller starts to work, collects the angle data of the main sensor, and transmits the data via wireless communication.

[0024] Furthermore, the working process of the high reliability wireless sensor device is as follows:

[0025] Step 1: After power-on, the system enters initialization, configures the working status of related modules, and then enters sleep mode. The high-reliability wireless sensor device wakes up regularly, or the wireless gateway sends a wake-up command to the high-reliability wireless sensor device to work; after the wireless sensor device is awakened, it is determined whether the main controller is working normally;

[0026] Step 2: When the main controller cannot work normally, determine whether the standby controller works normally;

[0027] Step 2.1: When the standby controller fails to work properly, this sensor fails and the process ends;

[0028] When the standby controller is working normally, determine whether the main sensor is working normally;

[0029] Step 2.2: When the main sensor works normally, the main sensor data is obtained, and then the backup antenna sends the data to the wireless gateway, and then the high-reliability wireless sensor device enters a dormant state;

[0030] Step 2.3: When the main sensor fails to work properly, the backup sensor data is obtained, and then the backup antenna sends the data to the wireless gateway, and then the high-reliability wireless sensor device enters a dormant state;

[0031] Step 3: When the main controller works normally, determine whether the main sensor works normally;

[0032] Step 3.1: When the main sensor is working normally, the main sensor data is obtained, and then the main antenna sends the data to the wireless gateway. Subsequently, the high-reliability wireless sensor device enters a dormant state; the main antenna sends the data and the data is synchronized to the standby controller at the same time; then, it is determined whether the standby sensor is working normally, and steps 2.1 to 2.3 are repeated;

[0033] Step 3.2: When the main sensor cannot work normally, the backup sensor data is obtained, and then the main antenna sends the data to the wireless gateway. Subsequently, the high-reliability wireless sensor device enters a sleep state; the main antenna sends data and the data is synchronized to the backup controller at the same time; then determine whether the backup sensor is working normally, and repeat steps 2.1-2.3.

[0034] Furthermore, the design standard of the high-reliability wireless sensor device refers to the mine safety and coal safety design, and the installation method is magnetic suction installation, fixed hole installation, and installation with matching structural parts;

[0035] Furthermore, the equipment information and installation information of the high-reliability wireless sensor device are printed on the surface of the shell in the form of a QR code or a bar code by a marking machine, and the code is scanned on site for installation, deployment and configuration.

[0036] A method for using a high-reliability intrinsically safe wireless inclination sensor system for mining, the method comprising:

[0037] The wireless gateway sends a timed wake-up command to the high-reliability wireless sensor device through wireless communication. The high-reliability wireless sensor device then collects angle data through the angle sensor. At the same time, the high-reliability wireless sensor device uploads the collected data to the cloud platform through the wireless communication of the chain network. The cloud platform conducts comprehensive analysis and judgment on the obtained data.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] The invention proposes a high-reliability mine-use intrinsically safe wireless inclination sensor system and a method of use. The sensor uses a dual-path redundant design and performs dual-machine backup to reduce the failure probability of the sensor. The failure of a single component does not affect the overall function, which fundamentally solves the problem of low reliability. At the same time, the sensor can monitor in real time, can promptly discover potential safety hazards, and take corresponding measures to prevent and deal with them, thereby reducing the incidence of accidents, ensuring safe production operation, and protecting the lives of workers.

[0040] The present invention is a high-reliability wireless sensor device. A single wireless sensor can perform wireless measurement without the need to lay out power and signal lines. Combined with a wireless detection system, it can meet application scenarios such as equipment pre-installation, post-installation, and later modification, reduce the difficulty of on-site deployment, improve system stability, and has low cost.

[0041] The present invention uses a high-precision angle sensor to measure the angle, and uses wireless communication technology to transmit the attitude sensor data to the cloud platform wirelessly.

[0042] The present invention is powered by batteries as a whole and adopts a low-power design. A single battery can meet a service life of up to 8 years. The overall device meets at least IP65 waterproof grade. The outer shell is made of polymer materials, and the main system part, the backup system part, and the power supply battery are sealed with epoxy resin, etc. to maximize waterproof and dustproof performance.

[0043] 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.

[0084] The topology of the wireless chain network is clear and the connection between nodes is simple and linear. This structure makes the network planning and management relatively easy.

[0086] Each node not only needs to receive data from the previous node, but also needs to forward the data to the next node accurately, so it needs to have both receiving and forwarding functions. This places certain requirements on the hardware and software design of the node. The node needs to have sufficient processing power and stable wireless communication capabilities.
