Problems solved by technology

[0003] Using a large number of different data collectors in the same system will make the system complicated, which is not conducive to integration and maintenance, and is also not conducive to centralized processing and uploading of data. In addition, traditional data collectors must work normally in severe cold areas It is necessary to use low-temperature resistant devices, which greatly increases the cost of equipment, which will form useless redundant high costs of the entire system

Embodiment 1

[0029] Such as figure 1 with figure 2 As shown, a sensor data collection box under severe cold conditions includes a device box body, and the device box body is provided with a power supply module, a sensor interface module, a data storage module, a data upload module, a programmable control module, and a heat preservation control module. The sensor interface module is used to receive real-time data collected by external sensors; the data storage module is used to store real-time data collected by external sensors; the data upload module is used to transmit real-time data collected by external sensors to remote data Monitoring center; the heat preservation control module is used to keep the temperature of the external sensors; the programmable control module is used to control the sensor interface module to receive real-time data collected by different types of sensors, and control the data upload module to transfer the external sensors The collected real-time data is transmitt...

Embodiment 2

[0040] The overall structure of the invention includes a power supply module, a sensor interface module, a data storage module, a data upload module, a programmable control module and a heat preservation control module.

[0041] Power module:

[0042] In order to adapt to a variety of sensors, the present invention adopts 3.3V, 5V, and 12V of the LM2596 switching power supply series to realize 24V, 12V, 5V, 3.3V and other voltages for external sensors; the advantage of using a switching power supply is: In the power supply circuit, under the excitation of the excitation signal, the transistor V works alternately in the on-off and off-on switching states. The conversion speed is very fast, the frequency is generally about 50kHz, and it can even be hundreds or close. 1000kHz. This makes the power consumption of the switching transistor V very small, and the efficiency of the power supply can be greatly improved, and its efficiency can reach 80%. From the principle block diagram of t...

Abstract

The invention provides a sensor data collecting box under severe cold condition, comprising a device box body. A power module, a sensor interface module, a data storage module, a data uploading module, a programmable control module and a heat preservation control module are provided in the device box body. The sensor interface module is used for receiving the real-time data collected by an external sensor. The data storage module is used for storing the real-time data collected by the external sensor. The sensor data collecting box can stably work under severe cold condition, is low in cost, high in stability, integrates collection, storage and uploading functions, and can accommodate a variety of sensors.

Description

Technical field [0001] The present invention relates to the technical field of sensor data collection, in particular to a sensor data collection box under severe cold conditions. Background technique [0002] In many areas with steep terrain, harsh conditions, extremely cold weather, and large temperature differences between day and night, it has great geological research value. Many sensors are designed to work in such an environment, but data collection equipment must be used to obtain data from these sensors. In general, sensors are equipped with corresponding data collectors, but in some large-scale systems, more than one type of sensor is used, and a large number of different data acquisition devices will be used in the same system. [0003] Using a large number of different data collectors in the same system will make the system complicated, not conducive to integration and maintenance, and not conducive to centralized processing and uploading of data. In addition, traditiona...
