Device for acquiring and wirelessly transmitting air quality data in forest environment

An embodiment of the invention discloses a device for acquiring and wirelessly transmitting air quality data in the forest environment. The device mainly comprises a CPU (central processing unit) module, an AD (analog to digital) conversion module, an RS232 serial port module, a GPRS wireless transmission module, a flash data storage module, a calendar time generation module, a temperature acquisition module and a power management module, wherein the CPU module exchanges commands and data with a forest environment air quality detection device through an RS232 serial port, on one hand, measurement data of the detection device are acquired, and on the other hand, the work state of the detection device is monitored. The temperature acquisition module is used for measuring the indoor temperature of an ecological station and is used for guaranteeing that the air quality detection device runs in an appropriate temperature environment. The AD conversion module can further be used for acquiring other environment data, adding timestamps for all acquired data and saving the data in a flash chip. Meanwhile, the GPRS module is adopted to wirelessly upload the acquired data and the working state information of the detection device to a network server, so that the means for acquiring air quality detection data of the forest environment becomes simple, convenient and reliable.

Satellite signal acquisition and tracking method and device, and satellite signal receiver

ActiveCN110058271AShorten the timeSolve the problem that the cold start takes a long timeSatellite radio beaconingHigh level techniquesNatural satellitePrior information
The invention discloses a satellite signal acquisition and tracking method and device, and a satellite signal receiver and a readable storage medium. Because the satellite signal receiver cannot obtain prior information during cold start, obtaining real-time geographic information such as real-time calendar time is easily; after a satellite signal cluster including a plurality of satellite signalsis received, the real-time geographic information is obtained, and the real-time geographic information is input into a pre-trained discrimination model for describing the relationship between the geographic information and satellite types to obtain satellite groups which meet search criteria, and the range of satellites for comparison search is reduced; then, pseudo-codes of the satellites in the satellite groups are used for searching in the satellite signals to obtain preset number of target satellite signals; and finally, the target satellite signals are tracked and locked. Because searching in the whole satellites is not required, the acquisition and tracking signal processing time of the satellite signals is greatly reduced, so that the problem of long time-consuming cold start of the satellite signal receiver can be effectively solved.

Climate- regulating- system

For many millennia's Earth has had an active and very effective process of controlling-limiting earth climate factors that have fostered the evolution of many varieties of life forms in both plants and animals. Earths two Polar ice fields have functioned as the controllers of earth's climate by cycling earth temperature in repetitive ice ages-periods followed by warming trends. Human activity, burning huge quantity of carbon fuels, has warmed the earth to the point now that the polar ice has significantly melted, and receded in area. Earth now is not capable of reverting to the prior state of stability. Now, press reports, scientific journals, and individuals, have published information supporting the prediction and observational fact that human controlled use of carbon containing fuels, are primarily responsible. Those carbon materials when burned in large quantity in machines created by humans have altered earth's climate.
Overview
Now earth's climate is critically changed and altered. Earth is no longer capable of maintaining, let alone restoring, natural systems that permit a future stable climate as was common in pre fossil fuel use. For a continuing stable climate, human designed, substitute controls, must be constructed and be made operational for earth to have an enduring future self-regulating and stable climate. Humans have created the situation where they must act and create methods for earth to maintain a suitable natural self-regulating-system in the future. Correcting the path that Earth is proceeding toward include plant and human life extinction, has been addressed, by scholars and academics, where a variety of possible solutions that perhaps can control, stop, reverse, the path earth is now on, those writings suggest a variety of corrections. Those subjects, writings, now are, classified, labeled as GEOENGINEERING. Out of the list of possible remedies for reversing, the direction of earth's deterioration, many have included, a SUN-SHIELD somewhat like one included herein. The calendar time during which humans must act to remediate change is limited, so prompt initiation of action is required. Most of the writers on this subject generally conclude that in space orbiting structures are too expensive, so they dismiss space located structures as one to follow or recommend. This inventor takes the position that humans should not compromise when selecting a path to correct earth warming. Extinction applies to all regardless of wealth. Therefore, cost cannot be a determining factor. The invention revealed here consists of a shield formed from suitable sheet cloth materials configured to have tight weavings that block light transmission through the material. That effectively blocks a portion of daily sunlight as it falls on earth. The shading effectively reduces energy from the sun that provides all the energy supporting life on earth surface. That sunlight also provides all the energy that powers weather events. The loss of polar ice now provides extra energy to the atmosphere, water exposed at the poles absorb much more energy than the snow and ice now disappearing. Extra energy results in more violent storms on mid latitudes, where abnormal levels of destruction now increasingly appear. The placement of the sun shield in earth orbit requires global coordination, leadership, and finance to install the shield. Launching shield materials from earth with Powerful high lift rockets well known for launching and positioning satellites will apply to this work. They are necessary to connect the shield in space to its supply source on earth. Deploying the shield is a worldwide social challenge, where humans from various cultures must cooperate and support efforts to deploy and maintain the shield in its operation.
