Biological investigation data mobile acquisition system

Abstract

The invention relates to a biological investigation data mobile acquisition system which comprises a PDA terminal and a network server end which are connected in a wireless or wired communication manner, wherein the PDA terminal comprises a GPS hardware module and a surveying point management module and is used for generating a surveying point record according to the GPS positioning information, registers, alters and deletes the surveying point to the network server end or performs navigation by using the existing surveying point; when the surveying point record is generated, a unique identifier GUID value is generated at random for marking the surveying point during the process of information exchange and updating between the PDA terminal and the network server end; and simultaneously, the PDA terminal further comprises a rapid data entering module, a data storage and transmission module, a counting device module, a WEB browser module, and the like. The invention can be applicable to the field data investigation of the scientific research in various industries such as agriculture, forestry, environmental protection industries, and the like, improves the integration of the software and the hardware in the prior art, avoids the data record from being confused, improves the working environment of the investigators and improves the working efficiency.

Description

technical field [0001] The invention relates to the field of scientific research and investigation of field data, in particular to a mobile collection system for biological investigation data. Background technique [0002] Investigating weeds, insects, plant diseases, etc. in the field is a basic task of scientific research in agriculture, forestry, environmental protection and other industries. It is necessary to record the geographical location of the survey site and the type, quantity, and shape of the surveyed object. Realizing the above functions requires GPS (Global Positioning System), PDA (Personal Digital Assistant) and other equipment. GPS can meet the needs of navigating destinations or accurately locating unknown locations in survey work, and PDA can realize Paperless information recording, GPS can be integrated with PDA through built-in or Bluetooth connection, and PDA with wireless communication function can also directly send data to a remote server in the fie...

Problems solved by technology

When entering survey information, it is necessary to fill in information such as the Latin scientific name and Chinese name of biological species. These information are not English words or commonly used Chinese phrases, and the number of characters is relatively large (for example, a Latin scientific name may be as many as dozens of letters). When using a PDA The input efficiency is very low when the input method is commonly used, and it is inconvenient to input information

When the number of survey objects is large, manual counting requires the use of auxiliary tools, and investigators also need to carry counters and other tools with them, which greatly increases the complexity of the implementation of the survey work

[0005] In addition, due to the traditional GPS survey point positioning and navigation equipment, only a simple coordinate point is provided to the staff, and if a second sampling is performed at the same location, the coordinate points displayed on the remote server are the same, so it is difficult to distinguish the sent back The actual situation represented by each of the two data, so it is easy to cause confusion in data records

Moreover, in the process of field operations, the reliability of network utilization is often greatly reduced. In the case of being unable to connect to the remote network server, the collected data is often not saved and transmitted in time, resulting in adverse consequences such as incomplete data collection.
