Features fire receiver: sensor networks deployed in the vicinity of 100-300m range, receive fire warning from the sensor network; remote transmission: SMS through GSM or GPRS, or wired network, sent to the management center via TCP / IP protocol (Wisdom forest platform); unattended: the fire position directly sent to the designated person by GSM mobile phone short message; fire alarm: send a strong drive alarm sound and light alarm, the role of range greater than 100m; network management: management of sensor networks routing, collection, inspection, etc; backup power supply: built-in automatic charge management and battery backup power to support 24 hours of work; self-healing: if unusual operating conditions, the device can automatically within 10 seconds to restart the forest fire prevention plan to prevent crashes and avoid maintenance. China Development and Prospect of Biological Fire ---- British card Electronics Co., Ltd., Chongqing (a) the enormous benefits of biological fire belt gradually been recognized by the whole of society to create a broad-leaved trees and economic fruit forest fire, one can change a single forest into mixed Lin, help to optimize the structure of forest tree species, suppression of forest pests and diseases, to maintain biological diversity; on the other hand opened fire on a ridge line in the original planted forest fire, to make full use of land resources, increase forest area, effectively reducing stormwater line of fire The red rinse, to prevent soil erosion, improve soil fertility plays a significant role. Some local construction administrative region at the junction and forest ownership boundaries biological fire protection, fire barriers and making it clear ownership boundaries, to stabilize the forest ownership, forest fires and reduce the incidence of disputes on how forest fire prevention, maintenance of forest District social order and stability, to protect the people's normal production and life order, promote social and economic development. Create biological fire protection point of burning fire line with the creation of adobe with the main measures are to prevent the spread of forest fires, but compared with the latter, green fire has many advantages. One can make full use of land resources. Creation of one kilometer per 10 meter wide barrier strip to be occupied by one hectare of forest land, the country currently occupies 380,000 kilometers require nearly 40 million hectares of land. Second, save and invest. Although after the initial construction of biological fire belt into a larger, but the maintenance and repair of biological fire belt "all-optical" type fire line compared to forest fire monitoring, saving labor and funding, it is understood in the line of fire planting superba, 4 years forest canopy, maintaining one hectare per year from Firebreak need 10 workers, and maintenance of one hectare fire line need 67 workers, compared to save 57 workers, workers 20 yuan per meter of forest fire prevention, can save 1140 yuan per hectare per year Maintenance funds only to reduce spending over a billion. The third is to prevent soil erosion. Most opened fire on the ridge line, hills, these places are generally steep, long-term removal of vegetation, will become barren, a case of heavy rain, most of the topsoil into the soil being washed away, some with trench formation, ground trough, wind fossils exposed individual lots. Fire burn point line will cause environmental pollution, occasionally causing the fire to run. Create a forest fire can avoid the above drawbacks.
