Description

A system and method for measuring and controlling the environment in a vehicle compartment

technical field

The invention relates to the technical field of environmental engineering, and more specifically, to a system and method for measuring and controlling the environment in a vehicle compartment.

Background technique

Transportation enables products to be transported from one place to another. This process is often a process of product value-added, but the transportation process will also cause product losses, which virtually increases production costs. In order to reduce the loss of goods during transportation, some appropriate measurement and control technologies are usually adopted to minimize the loss. Due to the different types of transported goods, the control methods adopted are also different, especially for food products. If improper measures are taken during the transportation process, it will inevitably cause a huge cost burden.

At present, in the transportation process of some perishable foods, the use of cold chain transportation will greatly reduce the quality loss of products during transportation. Therefore, the development of cold chain transportation equipment in various countries in the world has emerged in an endless stream over the years, but there are very few equipment for environmental control during the transportation of live agricultural and livestock products. The environment of the carriages during transportation is dirty and poor, not only the welfare of animals cannot be guaranteed, but also it will cause a great stress response to the living animals, which seriously affects the survival rate and quality of animal transportation, and even the quality of products at sales terminals such as meat products. Will be greatly discounted. The traditional method is that the personnel on the vehicle should always pay attention to the condition of the living animals, requiring a special person to take care of the vehicle, which increases the transportation cost and is inefficient. It can only appease the living animals that have already experienced stress reactions after the event, and cannot avoid stress in advance. The occurrence of the reaction cannot accurately collect the data changes of the mixed gas concentration and temperature and humidity in the transport compartment, which may easily cause stress reactions and even death.

The most important thing is that during the transportation of living animals, due to the respiration and excretion of animals, carbon monoxide, hydrogen sulfide, ammonia and methane will be produced in the compartment, and oxygen and carbon dioxide will exist in the air. In the transportation of living animals, oxygen needs to be maintained at a certain concentration to ensure the survival of animals; because carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, and methane will cause animal death or explosion hazards, carbon monoxide, carbon dioxide, hydrogen sulfide, The concentration of ammonia and methane needs to be controlled below a certain range to ensure the survival of animals and the safety of transportation.

Specifically, a measurement and control system for the environment inside a vehicle includes an environment detection module 11 and an environment control module 12 . The environment detection module 11 is electrically connected with the environment control module 12 to transmit electric signals.

After the environment detection module 11 obtains the concentrations of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the vehicle compartment, it transmits the obtained concentrations of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen to the environment control module 12.

After the environment control module 12 receives the concentration of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the compartment obtained by the environment detection module 11, it analyzes the concentration of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the compartment , when the concentration of any one of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the compartment is not within the appropriate range, adjust the gas concentration in the compartment so that carbon monoxide, carbon dioxide, hydrogen sulfide, hydrogen sulfide, The concentrations of ammonia, methane and oxygen are in suitable ranges.

The embodiment of the present invention obtains the concentration of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the compartment, and analyzes the gas in the compartment according to the concentration of carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, methane and oxygen in the compartment obtained.

The gas sensor array is used to detect various gases in the mixed gas. Several gas sensing regions are arranged on the gas sensor array. Each gas-sensing zone responds to each gas in the mixture, but produces a high response to only one gas and a low response to the others. Thus, the gas sensor array can generate responses to the various gases in the gas mixture.

In the embodiment of the present invention, the gas sensor array includes six sensing areas: a carbon monoxide sensing area, a carbon dioxide sensing area, a hydrogen sulfide sensing area, an ammonia sensing area, a methane sensing area and an oxygen sensing area.
