Description

A power failure SMS alarm device for farms

technical field

The utility model relates to the field of farm environment monitoring, in particular to a short message alarm device for a power failure in a farm.

Background technique

At present, domestic farms generally use environmental controller products to control the temperature of poultry houses. The environmental controller can use advanced sensing technology to collect multi-point temperature in the poultry house into the controller. According to the feeding process, through intelligent algorithms, it can automatically control heating, ventilation, humidification, and wet curtain pumps to precisely control and adjust the temperature in the poultry house. The ambient temperature can achieve the effect of adjusting and controlling the environmental factors in the poultry house. However, when there is a power outage, the environmental controller cannot work, and it is impossible to effectively monitor the power outages caused by various situations.

The inability to implement effective monitoring of power outages has the following disadvantages: First, with the promotion of intelligent control technology and the rise of cage equipment, the demand for automation equipment is also increasing, and sufficient power supply can ensure that automated breeding equipment can function. It will seriously affect the environmental control of the farm, and then affect the efficiency of poultry farming. Second, if the power outage of the farm is too long, if it cannot be discovered in time, it will have a catastrophic impact on the breeding, and the economic loss is unimaginable. If the information can be sent to the mobile phone in time during a power outage, the monitoring of the poultry house will be effectively realized.

The current domestic power outage monitoring and alarming mainly relies on power outage alarms, which rely on sound transmission for alarm reminders. The problem is that the sound from the alarm is too small to be heard from a distance; too loud a sound not only wastes battery power but also easily generates noise. , affecting the environment of the surrounding residents.
