Virtual Fence for a Household Farm
This project will be based on a farm to help prevent other animals from intruding into the poultry farm. It is a virtual fence that uses automated technology to control and prevent the entry of other animals in an estimated agricultural poultry farm of 2 hectares.
Project Aims and Objectives
- The project aims at automatically controlling the operation of preventing intruding animals into the poultry farm as well as the movements within the farm
- Increasing the profit of the poultry farm by reducing the labor and maintenance costs
- Besides, the project will help reduce the maintenance cost and also minimize the labor requirement
- Increased portability
- Easy modification and manipulation of the virtual fence
The project will help to protect the farm from illegal entry of intruders and other animals. It will recognize the illegal entrance into the farm then send signals to the LCD which gets displayed on the screen, and possible action is taken. It continuously monitors the intruder while employing less labor and maintenance cost (Squires, 2010, p. 239).
There are various constrains that come along with the application of this system. They include the sensitivity of the sensors- the sensors used to attain a peak sensitivity at 38 kHz carrier wave frequency. At this frequency, there is a superlative performance of the system. However, at this best performance level of peak frequency, false positive beam detection is experienced which is undesirable. Increasing the carrier frequency lowers the sensitivity (Squires, 2010, p. 245).
Design Overview, Innovation, and Feasibility
The virtual fence helps to control intruders from entering into the farm. Invisible beams are generated from the three laser pointers creates the virtual fence in the farm. The laser beams get received by the phototransistor which is the input signal for the microcontroller. The high level of the laser beam indicates the presence of the intrusion where as low-level intensity level will indicate the presence of no intruder in the farm. The message then gets displayed on the laser crystal display screen after which it gets sent to the mobile phone of the user using the GSM (global system mobile) technology. The laser pointers will help to locate the position of the intruder. Below is the block diagram for the virtual fence (Kubik, 2014, p. 116).
- Phototransistors receivers are used for receiving the laser beam
- The boundary monitor block is sued for sending alert signals to the peripherals
- The laser pointer are used for locating the position of the intruder
- The phototransistors are used for sensing the laser beam
- The GSM is used for sending messages on mobile phones and LCD screen.
This design is both innovative and appropriate for the communities of East Santo since it involves the use of sensors and microcontrollers. These communication devices allow automatic control of the system thereby increasing efficiency and reducing labor and maintenance costs.
Below is the flow chart of the working of the design.
The design of the virtual fence will require the following devices for it to operate under all conditions
- Laser crystal display which will help to display information on the screen
- Laser pointer for the position of the intruder
- Phototransistors for sensing the laser beam
- Since the process will be automated, there will be need for Power Supply
- Speaker that amplifies the sound within the farm
- Boundary monitor for sending alert signals to the peripherals(Kubik, 2014, p. 120).
Technology has boosted the fencing technique by providing an efficient and effective way of managing the farm while reducing the labor and maintenance cost.A system for restraining industrial machines can be made by the help of sensor network which forms a virtual fence from infrared beams. Once the virtual fence is constructed, it monitors the region boundaries and produces alert in the user interface. This system will help to assist the community of East Santo to solve the issue of fencing (Kubik, 2014, p. 130).
