Abstract
Description
Technical Field
[0001] This utility model relates to a three-element environmental measuring instrument based on MSP430. Background Technology
[0002] Existing multi-element weather stations require the collection of various conventional elements, such as temperature, humidity, and air pressure. When collecting these data, multiple devices are typically distributed across the observation field. The data logger collects data from multiple sensors, aggregates the data, and performs derived calculations. However, data acquisition from multiple sensors usually relies on distributed wireless communication. This distributed deployment presents several problems: it is relatively complex, requires significant space, and is difficult to maintain. When the wireless network fails, there is no communication between the devices, hindering real-time data linkage. Furthermore, the need for wireless connections to aggregate data to the logger makes communication failures prone to occur. Additionally, the limited data throughput of the communication interface leads to data loss and instability during second-level data acquisition. Therefore, to ensure reliable and stable data acquisition, the logger typically only collects minute-level data. Summary of the Invention
[0003] To address the aforementioned problems, the purpose of this invention is to provide a three-element environmental measuring instrument based on the MSP430, which centrally houses temperature, humidity, and air pressure sensors in one device. The MSP430 microprocessor directly connects to the three sensors, enabling direct acquisition of sensor signals without intermediate links. It can perform data sampling and statistical analysis at the second level, overcoming the problems caused by traditional distributed deployment.
[0004] To achieve the above objectives, the solution of this utility model is as follows:
[0005] A three-element environmental measuring instrument based on MSP430, used for on-site environmental monitoring, includes a measuring instrument housing, a temperature sensor, a humidity sensor, and a pressure sensor. A control circuit board with an MSP430 microprocessor chip is fixed in the measuring instrument housing. A signal acquisition circuit and a communication interface circuit are arranged around the MSP430 microprocessor chip on the control circuit board. The pressure sensor is fixed on the control circuit board and connected to the signal acquisition circuit. A temperature sensor connector and a humidity sensor connector are also provided on the control circuit board, connected to the signal acquisition circuit. The measuring instrument housing has a temperature sensor connector, a humidity sensor connector, a gas interface connector, and a communication interface socket. The temperature sensor connects to the temperature sensor connector on the control circuit board via the plug of the temperature sensor connector. The humidity sensor connects to the humidity sensor connector on the control circuit board via the plug of the humidity sensor connector. The gas interface connector has a pipe interface; a gas connection tube is inserted into the pipe interface of the gas interface connector and connected to the pressure sensor on the control circuit board. The communication interface socket connects to the communication interface circuit on the control circuit board via pins.
[0006] A further aspect of the solution is that the temperature sensor connector and the humidity sensor connector are located on one side of the measuring instrument housing, while the gas interface connector and the communication interface socket are located on the opposite side of the measuring instrument housing.
[0007] The solution further includes: the temperature sensor connector, humidity sensor connector, and gas interface connector are provided with external threads, and the temperature sensor connector, humidity sensor connector, and gas interface connector are fixedly connected to the measuring instrument housing through the external threads and nuts.
[0008] A further aspect of the solution is that the temperature sensor and the humidity sensor are respectively fixed in the temperature sensor connector and the humidity sensor connector, or led out from the temperature sensor connector and the humidity sensor connector via connecting wires.
[0009] The advantages of this utility model are: compared with the existing technology, it has the characteristics of simplification, high reliability, and real-time joint data acquisition in the existing three-element measurement.
[0010] 1. Simplify
[0011] The measuring instrument transforms the measurement of the three elements from a distributed setup to a centralized device, requiring only a pole and ventilation hood for deployment. It is simple to install, easy to use, easy to maintain, and compact in size.
[0012] 2. High reliability
[0013] This invention directly collects three elements without the need for communication between devices, effectively avoiding communication failures, and the device structure is simple.
[0014] This invention offers greater real-time performance than existing data acquisition systems. In addition to the aforementioned shortcomings, it overcomes the limitation of existing systems, which only allow for minute-level data acquisition due to the distribution of sensors. It achieves stable and reliable data acquisition at the second level. In particular, when this invention is used for sea level three-element data acquisition, its ability to acquire data at the second level effectively improves the real-time performance of data in fields such as meteorological forecasting and weather system monitoring, navigation and aviation navigation, and climate model construction.
[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

Figure 1As shown, the three-element environmental measuring instrument includes a measuring instrument housing 1, a temperature sensor 2 (platinum resistance thermometer), a humidity sensor 3 (humidity-sensitive capacitor), and a pressure sensor 4 (silicon resonant pressure sensor). The measuring instrument housing is assembled from profile plates and includes left and right end plates 101 and 102 and upper and lower cover plates 103 and 104. The left and right end plates 101 and 102 are connected and clamped to the upper and lower cover plates 103 and 104 by long bolts 105 to form a closed housing. A control circuit board 5 with an MSP430 microprocessor chip is fixed in the measuring instrument housing. The control circuit board 5 is surrounded by the MSP430 microprocessor chip 6 and has a signal acquisition circuit, a communication interface circuit, and a memory unit. The signal acquisition circuit includes signal acquisition circuits for the temperature sensor 2, humidity sensor 3, and pressure sensor 4 respectively. The signal acquisition circuit for the pressure sensor 4 is a frequency acquisition circuit. These circuits are conventional acquisition circuits composed of operational amplifiers. The pressure sensor 4 is fixed on the control circuit board 5 and connected to the signal acquisition circuit. A temperature sensor connector 501 and a humidity sensor connector 502 are also provided for connection to the signal acquisition circuit. A temperature sensor connector 7 (with temperature sensor 2), a humidity sensor connector 8 (with humidity sensor 3), a gas interface connector 9, and a communication interface socket 10 are respectively provided on the measuring instrument housing. The temperature sensor 2 is connected to the temperature sensor connector 501 of the control circuit board 5 via the plug of the temperature sensor connector 7. The humidity sensor 3 is connected to the humidity sensor connector 502 of the control circuit board 5 via the plug of the humidity sensor connector 8. The gas interface connector 9 has a pipe interface 901 inside the housing. A gas connection pipe 11 is inserted into the pipe interface 901 of the gas interface connector 9 and connected to the pressure sensor 4 on the control circuit board 5. The communication interface socket 10 is connected to the communication interface circuit on the control circuit board 5 via pins. The communication interface uses an RS232 interface. The information processing server retrieves the ambient temperature, temperature, and pressure information collected by the MSP430 microprocessor through the RS232 interface.
[0018] In this embodiment, for ease of operation: the temperature sensor connector 7 and the humidity sensor connector 8 are disposed on one end face of the measuring instrument housing, such as... Figure 1 As shown, the right end plate 102, the gas interface connector 9, and the communication interface socket 10 are located on the opposite end face of the measuring instrument housing, as shown. Figure 1 The left end plate 101 shown has a positioning hole 101-1 for positioning the measuring instrument. In actual application, the measuring instrument can be positioned at the monitoring position through the positioning hole 101-1.

The temperature sensor connector, humidity sensor connector, and gas interface connector are fixedly connected to the measuring instrument housing through the external threads and nuts, which facilitates the installation and fixing of the connectors.
[0020] For greater flexibility, the temperature and humidity sensors can be fixed in the temperature and humidity sensor connectors respectively, along with the housing, at a monitoring position, or they can be led out from the temperature and humidity sensor connectors via connecting wires, making it easy to select the optimal detection point. Of course, the gas interface connector 9 also has an external pipe interface 902 on the outside of the housing, which is convenient for connecting gas pipes and facilitating the location of gas sampling points. A dust filter is provided in the gas interface connector 9.
[0021] The MSP430-based three-element environmental measurement instrument described in the above embodiment overcomes the distributed acquisition defects caused by the distributed setting of various sensors in the existing acquisition system. It can achieve stable and reliable data acquisition. In particular, when this utility model is used to calculate sea level air pressure, it can calculate sea level air pressure data at the second level because it can perform second-level data acquisition of the three meteorological elements. This can effectively improve the real-time data in fields such as meteorological forecasting and weather system monitoring, navigation and aviation navigation, and climate model construction.
