Independent systems for collecting and transmitting data with a wireless communication channel

Abstract

The need for the protection of material property appeared together with the notion of "private property", that is, immediately after the collapse of the communal system. The desire to hide, to find a cozy place to store such property is at the level of instincts, in this person does not differ from the animal. Therefore, the first stage in the development of a conscious action to prevent the location of the place of storage of property was the commission of special protective and preventive measures. From all sorts of ditches and stones, which laid holes for access to places of storage, humanity in the process of evolution gradually switched to the use of auxiliary devices. The main purpose of the security system (burglar alarm) consists in operative and guaranteed notification of the hosts or law enforcement agencies about unauthorized entry into the premises that are guarded. The decision of this task is possible only with the competent equipping of the object of protection with modern high-reliability technical means of the security alarm system.The security alarm system can be autonomous - the purpose of such an alarm is to scare off the attackers and announce neighbors with the use of powerful sirens. But the greatest effect of the burglar alarm is achieved by connecting it to the remote control unit or on the central monitoring panel of the private security company.Systems of any complexity are built on the basis of the same technical devices. When solving technical tasks of security, it is first necessary to choose the basic parameters of devices that will provide sufficient reliability of the functions assigned to them. The system of the security alarm fixes the fact of unauthorized access to the protected area, transmit an alarm, for example, to the remote control and include executing devices. The system of the security alarm system includes: sensors, remote-concentrator, actuating devices.Independent systems that read and transmit information are up to date, thanks to individual sources that allow the device to function independently, without communication with power systems. They use them where the objects are impossible or problematic to connect to the main line of power supply. The main advantage of this system is that the device can function continuously, regardless of the stationary power supply. This is important when using appliances that require constant power, such as signaling or autonomous heating. Therefore, these systems have become widely used, they operate in stand-by mode and are characterized by low energy consumption, but energy is not endless., considered various options for recharging and options for the implementation of data transmission. In order to restore energy resources, various options for recharging have been considered and proposed. Also, to save energy, various ways of data transmission, their advantages and disadvantages in the energy plan, dependence on external factors, range of action and method of information transmission were considered. On the basis of this, the conclusions drawn were drawn on the most suitable for the use of the transmission system in stand-alone systems, which in turn have less power consumption and the most optimal for data transmission, and also considered the expediency of using certain charging methods depending on their advantages.
