Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil measurement, and particularly relates to a wireless soil measurement instrument block type integrated design system. BACKGROUND

[0002] In the process of soil research, parameters to be measured include soil temperature, soil humidity, soil salinity, soil PH value and the like. In the process of measuring soil parameters, soil measurement instruments not only need to measure various parameters of soil, but also need to measure data of different depths of soil. The original method is as follows: a deep pit is dug, and sensor units are placed at different depths according to needs, and data of the underground sensor units are collected through a cable. Traditional detection instruments generally have a local display unit, which facilitates detection personnel to read instrument data on site and record them. Instant data can be detected immediately without backfilling soil, and if more real data is needed, the detection must be started after the soil is stabilized.

[0003] Soil data detection not only needs instant detection data, but also needs long-term monitoring of various parameters of soil in many cases. Traditional instruments need detection personnel to check and record detected data every day, which is time-consuming and laborious. SUMMARY

[0004] The application aims to provide a wireless soil measurement instrument block type integrated design system to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the application provides the following technical scheme: a wireless soil measurement instrument block type integrated design system, comprising: a sensor unit, wherein the sensor unit is separately packaged; a central unit, wherein the central unit is separately packaged; a wireless communication unit, wherein the wireless communication unit is separately packaged; a power supply unit, wherein the power supply unit is separately packaged; an alarm unit, wherein the alarm unit is separately sealed; an expansion unit, wherein the expansion unit is separately packaged; The sensor unit, the central unit, the wireless communication unit, the power supply unit, the alarm unit and the expansion unit are all provided with cylindrical shells with waterproof function, and adjacent cylindrical shells can be connected to each other. The various units can be combined together, and sealing gaskets are arranged at the joints to ensure mechanical strength and stability after combination, multiple units are combined to form an integrated measuring instrument, the multiple units are electrically connected by waterproof terminals, and the four-core interfaces of the units are connected, two of which are for power supply, and the other two are for half-duplex 485 communication.

[0006] As a preferred embodiment, the power supply unit uses a disposable battery.

[0007] As a preferred embodiment, the waterproof level of the cylindrical shell is set to IP68.

[0008] As a preferred embodiment, the number of power supply units, wireless communication units and sensor units is greater than or equal to one.

[0009] Compared with the prior art, the technical effects and advantages of the present application are: 1. The entire instrument is divided into different units, each unit is produced separately, which greatly improves production efficiency and facilitates packaging, storage and transportation; 2. Ultrasonic welding process is used, the shell of each unit is composed of upper and lower shells, the upper and lower shells can be tightly buckled together, and the contact surface between the upper and lower shells is directly fused together by ultrasonic welding process, achieving excellent mechanical strength and sealing effect.

[0010] 3. The shell is made of a waterproof material with high strength and toughness, which is difficult to damage during normal use and reduces the probability of being randomly damaged on site; 4. Each sensor unit can work independently, and the entire system is in a master-slave structure, the sensor unit is in slave mode, and there is no mutual interference between the sensor units; 5. The power supply of the sensor unit is controllable, and the sensor unit can be set to a power-off state when not working, which not only avoids the disadvantage of excessive power consumption of some sensors, but also prolongs the service life of some sensors; 6. The 485 bus structure is used between different units, the wiring is simple, and at most 128 units can be connected in series; 7. The central processing unit in the present application uses ultra-low power consumption technology, so that the instrument can be maintained for a longer time; 8. The communication between the units uses a standard and open communication protocol, so that modules that meet the communication protocol can be connected, which facilitates system expansion; 9. According to the needs, the instrument can be connected to multiple power supply units, which is convenient for customers to collect data intensively without worrying about insufficient power; 10. Each unit does not require potting compound. When needed, it can be completely removed by opening the waterproof shell with a special tool, which is convenient for maintenance or hardware upgrades. After the operation is completed, it is only necessary to replace the shell and reseal it, which greatly saves costs. 11. Depending on the needs of use, not only can similar sensor units be combined together to test the same type of data at different depths, but different types of sensor units can also be flexibly combined to measure different types of data at the same location. 12. With the advancement of technology, the corresponding functional units can be flexibly replaced and upgraded without affecting the normal use of other units; 13. When the testing project is completed or the soil parameters to be measured are changed, the soil measuring instrument of this invention can be dug out of the soil, the outer shell can be cleaned, and the instrument can be disassembled into individual independent units. When needed, it can be reassembled according to the new requirements and used repeatedly, which greatly saves costs. 14. When a problem or malfunction occurs in a certain unit, the corresponding unit can be replaced individually, which facilitates maintenance and repair, saves time, effort and money, and avoids unnecessary waste; 15. Because the instrument is buried in the soil, it can sometimes be difficult to find. Therefore, the instrument is designed with an alarm unit. When the wireless module malfunctions, the alarm module will automatically sound an alarm at regular intervals. When the instrument's wireless module receives an alarm command, it will also issue an audible and visual alarm. Attached Figure Description
