Closely related to the growth of fish and the water dissolved oxygen, dissolved oxygen in the water not only affects the growth and feeding of fish, but also directly lead to death in severe fish. So, aquaculture production becomes the mainly factor in improving the amount of dissolved oxygen. Oxygen pump, which is to increase the amount of dissolved oxygen in water is an electromechanical device that is widely used in our country.Nowadays,the most used is manually controlled air pump, aquaculture staff decide whether to open the aerator by observing he situation of fish floating head, this approach may result in insufficient oxygenation caused large fish deaths. Another way is to control the oxygen pump automatic control system, dissolved oxygen and dissolved oxygen limit set by the oxygen sensor detects oxygen compared to decide whether to activate the pump, the weak point is thatwhen oxygen pump fails farming were unable to detect.In order to reduce the cost of farmers, increase aquaculture production and accelerateautomation aquaculture, development of a remote monitoring system ponds oxygen is necessary. Circuit remote control system based on GSM ponds oxygen pump includes microcontroller circuit, data acquisition circuit, power circuit, liquid crystal display circuit, device control interfaces, GSM wireless communication modules and other components. Whenthe dissolved oxygen is not set range, the system automatically starts the pump oxygen environment parameters simultaneously send SMS text messages to a designated phone to remind farming staff. Aquaculture staff can also send SMS text messages remotely controlled oxygen pump start and stop. And when the oxygen pump fails, water dissolved oxygen decreased rapidly, the system will make a call to a designated phone in the shortest possibletime in order to promptly notify the breeding staff turned spare air pump, so this set of equipment to improve the pond water soluble security oxygen environment.Through testing, the system can automatically monitor temperature, dissolved oxygenmonitoring water ponds, so that the amount of dissolved oxygen is always in between5mg/L~9mg/L. When the dissolved oxygen contents under5mg/L, oxygen pumps automatically turn on, sending an alarm message, alarm sound and light warning light almost simultaneously.15min after starting again collected oxygen pump oxygen content, if not rise immediately send a designated phone call. During the test, the time delay to send text messages ab out13s, call delay of about10s.
