Description

Inventory sensing device, distribution system and distribution method for barreled liquid gas

The present invention relates to an inventory sensing device, a distribution system and a distribution method, in particular to an inventory sensing device, a distribution system and a distribution method for barreled liquid gas.

Gas is an important item for people's livelihood. In addition to water heaters, it is also an essential source of heat energy for cooking. The existing gas supply methods are divided into natural gas and barreled liquid gas, each of which has a considerable number of users. Except for the natural gas installed in the apartment buildings when they were newly built, most of them still use barreled liquid gas. Although natural gas is convenient and does not take up space, in addition to billing by the meter, it is necessary to pay an installation fee first when installing natural gas, and must pay the basic fee on a monthly basis, and users at the end of the natural gas pipeline are easy to use in winter. When the air pressure drops, it becomes difficult to use. In contrast, barreled liquid gas needs to pay the cost of buying a barrel when it is used for the first time, and then only buy gas according to the consumption, which greatly reduces the cost. In addition, the barreled liquid gas has a higher thermal mass than natural gas, which can provide higher heat in use, and because the installation of barreled liquid gas is simpler than that of natural gas, barreled liquid gas is still the gas supply. important way and also an option used by the catering industry.

However, barreled liquid gas is a dangerous fuel and must be stored in a closed steel container, and its stock cannot be observed with the naked eye, and the sensor cannot be installed and penetrated into the steel container, making barreled liquid gas less easy to know. For the remaining amount inside, after the user runs out of barreled liquid gas, the user should notify the gas supplier to replace the gas cylinder. Knowing in advance creates a dilemma for suppliers not being able to deliver immediately. Today's gas suppliers still use the service mode of maintaining telephone calls, that is, passively waiting for customers to notify them when they have run out of gas, and then change the service; ordinary users often find out that the gas is out of gas when they are eating, and then notify the gas delivery. At this time, it was the peak traffic period, and the deliveryman was exhausted and could not quickly deliver the new gas cylinders to all the customers' residences; not only did the customers complain, but the deliveryman delivered in the chaotic traffic, causing a traffic accident. The chances are also greatly increased.

In addition, some people use a weight sensor to test the remaining amount of gas in a steel container, but all kinds of weight sensors can not withstand the pressure for a long time, for example, the elastic elements are elastic fatigue phenomenon, after the sensor is used for a long time , it is easy to cause damage to the sensor or loss of accuracy. Some people use the air pressure sensor to sense the air pressure to predict the stock of liquid gas, but in a closed container where liquid and gaseous gas coexist, the pressure is the saturated vapor pressure, which is easily affected by the temperature and causes the air pressure sensor to sense inaccurately, and The saturated vapor pressure will only drop significantly when the liquid state completely disappears, so it is impossible to warn the safety stock in advance.
