Introduction
Now Yaroslavsky Broiler is the only specialized enterprise in production and processing of meat of broiler chickens in the Yaroslavl region. Today in the company there is a closed production cycle: from the production of hatching eggs to the finished product. A distinctive feature of the factory is its own network of company stores and its own fleet of vehicles and the availability of wholesale warehouses make possible the quickly delivering of meat products to the consumer, including central and remote regions of Russia.
Poultry farm has about 20 chicken houses with about 5 rooms in each. As the equipment for automation of the poultry breeding in the factory the poultry automation of the 'Big Dutchman' (http://www.bigdutchman.com) company is used, it is represented by specialized computers Viper, one in each room.
However, the decision of the company for the operational process monitoring ('Infomatic') has the set of limitations on productivity, which is further exacerbated by a large number of specialized computers and large amounts of data from one computer (200-500 signals). Since data from the room computers are concentrated in one BFN(BigFarmNet) module, and then are acquired by the dispatching program. The specialized software for the modules' acquisition makes the acquisition of the BFN module of one chicken house within five minutes, and can not make a parallel inquiry of the BFN modules of separate chicken houses, that in total is approximately 1.5 hours to update data for all twenty poultries. Naturally, this can not be called the operational control and the factory decided to solve the problem.
1. Work
To solve this problem, it was decided to implement optimized and compact inquiry of the BFN modules' data of the chicken house in the amount of the current values of signals and alarms in parallel mode. Since the OpenSCADA system has developed mechanisms for data acquisition, storage and presentation, as well as it is an open system, it was decided to write the BFN acquisition module for it.
As a result of the work it was written the module of the BFN inquiry, which allows you to acquire all the controllers' data, which are connected to the BFN of the chicken house with alarms for each. In general, the amount of obtained data from one chicken house (6 rooms) is 1500 signals with an average time of inquiry - 12 seconds. As the inquiry of an individual chicken house (BFN module) is made regardless, the total time of the inquiry of twenty chicken houses will be those same 12 seconds. Archives of signals, as required, are included and stored in the OpenSCADA system with optimization on access time and size that allows you to fully control the history of the process.
Acquisition and visualization of data of the poultry are implemented on the dedicated server, the dispatcher's station and the direction's workplaces:
- The dedicated server is implemented on an office PC with Intel Atom D520. On the server the inquiry and data archiving of the chicken houses (BFN modules) are running.
- The dispatcher's station is implemented on an office PC with Intel Atom D520 and is used for operational control of the process through the data obtained by the dedicated server.
- On the direction's workplaces the Web-based interface through the dedicated server is provided to assess the current state of the process and its history.
Visualization interface is represented by two signal objects with the following composition:
- 'General': The main mnemonic scheme of the poultry contains the chicken house blocks with the set of the rooms and their alarms.
- "Chicken house 1": The chicken house mnemonic scheme with the table of the selected signals and their alarms; alarms report of the chicken house with their history.
There is the possibility of expanding the visualization interface by adding a new chicken houses to the signal objects and to the main mnemonic scheme by copying the first chicken house.
