Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to a universal multi-interface low-power Internet of Things data acquisition controller. Background Art

[0002] With the improvement of industrial automation level, the process of data collection is often linked with industrial control links to form a complete data collection and monitoring system. Many business departments such as environmental protection, meteorology, electricity, industrial automation and other industries, as well as scientific research fields such as military, ocean, hydrology and ecology, often have a large amount of widely distributed field data that needs to be remotely automatically collected, stored and transmitted. The sensing, monitoring and control network based on the Internet of Things is becoming more and more popular. Its key link lies in data acquisition and transmission. It is through the data collector terminal that massive environmental data is gathered and uploaded to the network, such as analog current and voltage signals representing various physical information, digital signals, image file information, etc., for subsequent data analysis and equipment control. At present, most of the Internet of Things data collectors are aimed at a specific field or specific functional demand scenario to realize specific data collection and control functions, such as large-scale regional hydrological monitoring and governance, agricultural and forestry ecological monitoring, geological and geographical monitoring, pipeline line monitoring, road traffic real-time monitoring and energy consumption equipment monitoring and other collection controllers. Data collectors for a specific field or application scenario often have fixed sensor hardware interfaces or software protocols, and a single networking or networking method, which cannot be compatible or quickly and conveniently expanded to other fields or scenarios. Therefore, some manufacturers have also tried to develop multi-functional general data collectors. For example, some have added sensor interfaces and communication protocols, some have added access network communication methods, and some have focused on low-power applications, etc., which have broadened the application scope of the collector to a certain extent. However, there are no data collection controllers that can truly meet the data collection and monitoring needs of most occasions and functional requirements in the current industrial control field. Therefore, a general low-power IoT data collection controller that can be suitable for most IoT monitoring and control scenarios and field requirements has good application value and market prospects. Summary of the invention

[0011] Furthermore, the minimum system functional circuit includes a crystal oscillator, a reset circuit, and a SWD download interface.

[0019] Furthermore, a button battery is arranged in the core base plate.

[0020] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0021] 1. A variety of access networks and networking methods, wired or wireless, can be networked through public networks or private networks. Access network methods include Ethernet, wireless WIFI and 4G, which are suitable for applications in scenarios covered by public networks. Indoor or short-distance communications can be achieved through Ethernet or wireless WIFI, and outdoor or large-area application scenarios can be connected through 4G. In areas not covered by the public network, WIFI and LORA self-organizing networks can also be used. Short distances can be achieved through WIFI LAN, and long distances can be achieved through LORA self-organizing networks. The collector can be used as a LORA node or LORA gateway according to needs and application scenarios, which can fully meet most IoT monitoring and control scenarios and field requirements. Existing IoT collectors usually only use 1 to 2 of these access network methods for a specific scenario.

[0022] 2. Rich sensor hardware interfaces and software protocols. Sensor parameters can be configured on-site or remotely, and sensor port protocols can be modified remotely. Select sensors with corresponding functions according to different application fields. Sensor interfaces include RS485, RS232, UART, SDI-12, CAN, pulse, switch quantity and other digital signal interfaces, 0-5V voltage / 4-20mA current analog signals, RJ45 network ports, etc. The corresponding sensor configuration information can be written to the SD card through the card reader or set through the corresponding remote cloud platform client. When the sensor port protocol needs to be modified, it can be achieved through remote firmware upgrades. Traditional data collectors are often targeted at a specific field and application scenario, with fewer interface types, fixed protocols, and cannot be modified remotely.

[0023] 3. Various interface function modules are selected and reused. Under the premise of meeting the requirements of different application scenarios and functional fields, the limited interface resources of MCU are utilized to the maximum extent, the overall structure size of the collector is effectively reduced, and the product cost is reduced. In terms of the hardware structure design of the core baseboard of the collector, except for the general functional circuits such as power management circuit, MCU minimum system circuit, storage circuit, sensor interface drive circuit, etc., independent modular design is adopted. Each functional module is designed through stamp holes or board connectors. It is selected and welded to the core baseboard according to the application scenario and functional requirements, and then the software mode selection is realized through the corresponding DIP switch. And the same functional modules share MCU interface resources and structural space. For example, the Ethernet interface module and WIFI module in the data upload mode share an SPI interface and space, the Bluetooth and RS232 modules in the device debugging interface module share the same UART interface and space, and the RS485 and SDI-12 in the general sensor interface share the same UART processor resources.

[0024] 4. System-level low-power design. The hardware design uses high-performance low-power MCU, high-efficiency power conversion chip, extremely low quiescent current power switch control device and low working current functional chip and module. The software controls the power supply of the corresponding module circuit according to the workflow, shuts down the power supply of all functional modules in the standby state, and the main control enters the lowest power consumption shutdown mode. The acquisition controller MCU uses ST's STM32L476 low-power processor, and the Energybenchmark score reaches the industry-leading 294 ULPMark™ CP score. The shutdown mode current is about 300nA. The power control device of each module uses TI's high-performance MOSFET switch, and the quiescent current is less than 10uA. The acquisition controller system is tested with a current of less than 500uA in low-power mode, and its performance is significantly better than its similar multi-functional general collectors.

[0025] 5. The collector can be used for data collection and monitoring in most application occasions and functional requirements. For example, in the field of agricultural Internet of Things, it can realize the environmental temperature and humidity in the agricultural production process, soil temperature, moisture, fertility and other sensor data collection, and upload them to the cloud server in a variety of networking methods. After corresponding analysis and processing, it can perform specific control operations such as sprinkler irrigation, drip irrigation, supplementary lighting, heating, ventilation, shading, and CO2 supplementation. The sensor interface in this field is usually UART, RS485, 0-5V analog input, pulse, switch input and output, etc.; in the field of hydrology and water quality monitoring, water safety indicators are realized, including turbidity, residual chlorine, dissolved oxygen, PH, temperature, COD, DO and other water quality related parameters monitoring. The sensor interface in this field is mostly RS485, SDI-12 and analog etc., and are often located in the wild, requiring low-power design; in the field of agricultural and forestry ecology, large-scale remote monitoring of forest growth is achieved. This field is mostly remote and wild, without network coverage, and requires private network networking to transmit and collect data; in the field of geological and geographical disaster monitoring and early warning, stress sensors or image sensor information is used to achieve landslide monitoring, debris flow monitoring, slope monitoring, settlement monitoring, collapse monitoring, ground collapse monitoring, dam monitoring, tunnel monitoring, bridge monitoring, etc. This field often requires image sensors, and the interface is generally an RJ45 network port; in the field of industrial equipment energy consumption monitoring, the real-time energy consumption data of energy consumption metering equipment such as electricity meters, water meters, gas meters, and oil meters can be automatically collected, analyzed, processed, and reported. The sensor interfaces in this field are mostly CAN and RS485. BRIEF DESCRIPTION OF THE DRAWINGS
