Capacity sensing device

Abstract

The invention relates to a capacity sensing device, which is used for measuring the volume of an article in a holding space and comprises a first transmitter and a receiving device. The first transmitter is disposed in the holding space and transmits first signals, and the receiving device is arranged at an opening of the holding space, receives the first signals and calculates the capacity of the article according to signal strength of the first signals.

Description

【Technical field】 [0001] The invention relates to a capacity sensing device, in particular to a device for detecting storage capacity by sending and receiving wireless signals, which can detect the storage capacity of liquid or solid. 【Background technique】 [0002] The management of real-time internal storage capacity of storage or the real-time capacity of liquid tanks is an urgent problem for existing enterprises. The main thing is to be able to control the utilization rate of storage or liquid tanks, so that managers can make better resources. distribute. [0003] To manage the storage in the warehouse, most of the common technologies set barcodes or RFID on the outer packaging of the boxes to be stored to correspond to the codes of the boxes. When the boxes enter the warehouse, the administrator uses the reader to read the above codes and store them in the Management control in the warehouse management software. When the box leaves the warehouse, the administrator need...

[0003] To manage the storage in the warehouse, most of the common technologies set barcodes or RFID on the outer packaging of the boxes to be stored to correspond to the codes of the boxes. When the boxes enter the warehouse, the administrator uses the reader to read the above codes and store them in the Management control in the warehouse management software. When the box leaves the warehouse, the administrator needs to read the code again and delete this data in the warehouse management software. The advantage of using the code corresponding to the box to manage the warehouse is that it can have precise control However, it needs to spend the cost of coding management and it is necessary to ensure that all cabinets have been equipped with barcodes or RFID. If the barcodes or RFIDs are defaced or fall off, it may not be managed correctly. In addition, if the cabinets are stolen, It is also necessary to count all the cabinets to know the missing cabinets, which causes difficulties in management

[0004] In addition, in the measurement of the capacity of the liquid tank, the common technique is to use the height of the float to manage. When the float floats on the liquid surface and exceeds a certain height, the mechanism connected to the float will start the motor to enter the water. When the float is lower than A certain height will stop the motor from entering water. This method is often used in the management of water towers in homes. This method can manage water inflow and inflow, but it is impossible to know the real-time height of the current water level; Hit the airtight container to generate a sound signal, and there is a storage in the airtight container, the sound receiving device collects the sound signal and transmits it to the signal analysis device, and obtains the amount of the storage in the airtight container by analyzing the sound signal, although it can be obtained Immediate capacity, but not perfectly suitable for all tanks, for example, brick storage tanks cannot use the means of tapping airtight containers
