Air conditioner centralized control system for granary

Abstract

The invention discloses an air conditioner centralized control system for a granary. Multiple air conditioner indoor units are installed in a warehouse of the granary. The air conditioner centralizedcontrol system for the granary mainly comprises air conditioner remote controllers, six-axis sensor modules, infrared emission modules, communication modules and a centralized control box. The air conditioner remote controllers, the six-axis sensor modules, the infrared emission modules and the communication modules correspond to the air conditioner indoor units, and the centralized control box isinstalled outside the warehouse of the granary. Each six-axis sensor module is installed on the outer side of a fan blade in an air outlet of the corresponding air conditioner indoor unit, and each infrared emission module is installed on the corresponding air conditioner indoor unit. The six-axis sensor modules, the infrared emission modules and the communication modules are connected with the air conditioner remote controllers. Each air conditioner remote controller is connected with the centralized control box. According to the air conditioner centralized control system for the granary, the air conditioner control mode extends to the exterior of the warehouse under the condition that an existing air conditioner indoor unit installation structure is not destroyed, and the situation thatthe warehouse is kept in the airtight state in the whole cold supplement operation period is ensured. Due to the fact that all air conditioners of the warehouse are subjected to centralized remote management and control in the mode that the warehouse serves as the minimum unit, the human cost is reduced, and the real-time states of the air conditioners can be effectively and really monitored.

Description

technical field [0001] The invention relates to the field of grain depot management and control, in particular to an air conditioner centralized control system for grain depots. Background technique [0002] my country is a country with a large population, and it is also a country with a large grain storage. The development of the country cannot be separated from grain, so it is particularly important for grain storage. On the basis of conventional grain storage technologies such as ventilation, fumigation, and controlled atmosphere, the country has begun to test, demonstrate, and promote the application of green and environmentally friendly grain storage technologies such as low-temperature grain storage and controlled atmosphere grain storage in large grain depots. The low-temperature grain storage technology uses the cold energy generated by the refrigerator to cool, cool and dehumidify the natural air. The cooled air passes through the grain pile through the fan and the ...

AI Technical Summary

Problems solved by technology

During the whole process, personnel need to enter the warehouse at least twice, which means that the door of the grain surface needs to be opened at least twice. When the temperature of the grain surface reaches a quasi-low temperature condition, this will inevitably cause cold air to leak out, thereby causing waste of resources

[0004] Through on-the-spot investigation and understanding of the actual needs of warehouse managers for air-conditioning control, extending the air-conditioning control mode to outside the warehouse is an effective measure to solve the above problems. However, many commercial air conditioners on the market do not have remote control interfaces, and need The system design is carried out on the basis of the completed air conditioner, and the control mode of the air conditioner is not modified in principle to avoid after-sales disputes

At present, the remote controller of the air conditioner on the market monitors the status of the air conditioner by installing a current transformer on the power line of the air conditioner, and monitors whether the air conditioner is really turned on through the current change of the transformer. , or destroy the wall, and put the transformer on the live line of the switch panel. The way of destroying the wall will cause the system installation cost to be too high, which is not conducive to promotion, and it is easy to affect the airtightness of the warehouse

The method of breaking the power cord of the air conditioner will inevitably damage the integrity of the air conditioner and cause after-sales disputes. In addition, this method cannot monitor the temperature setting status of the air conditioner.
