Abstract
The invention discloses a pressure-sensor-contained RFID tag for a chemical pump. The pressure-sensor-contained RFID tag comprises an RFID circuit, an antenna, a pressure sensor, and a fluid sensitive switch. A first terminal of the antenna is connected with a first signal output terminal of the RFID circuit; a signal output terminal of the pressure sensor is connected with a pressure signal input terminal of the RFID circuit; a first terminal of the fluid sensitive switch is connected with a second signal output terminal of the RFID circuit; and a second terminal of the fluid sensitive switch is connected with a second terminal of the antenna. According to the invention, pressure monitoring of all points in the chemical pump can be realized; and the manual error can be reduced. Meanwhile, the RFID tag functions can be expanded comprehensively. Therefore, the RFID technology has the wide application prospects in the mechanical engineering field.
Description
Technical field
The present invention relates to the RFID label tag for chemical pump, particularly relate to a kind of RFID label tag for chemical pump band pressure transducer.
Background technology
In Chemical Manufacture, be link very important during chemical industry is done to the monitoring of pump pressure.General, to pump pressure monitoring, be generally carry out reading by tensimeter.Traditional tensimeter can monitor out pump inlet and outlet pressure, but imports and exports pump and far away be difficult to monitoring, often needs to think in addition and patrols and examines, could read inlet and outlet pressure.If there is a kind of equipment, can monitoring pressure at any time, producing guaranteeing both quality and quantity of producing, is very important.Data can be made on the one hand more accurate, and the pressure data in position monitor production at any time in chemical pump, can eliminate the error that artificial origin causes on the other hand, can also reduce the labour intensity of workman.
Electronic tag, also known as radio-frequency (RF) identification, is a kind of contactless automatic identification technology.By the radiowaves launched at a distance of several centimetres to several meters distance inner sensors, the information that can store in reading electronic labels, the identity of the article of identification representated by electronic tag, people and utensil.Pressure transducer is one of the most basic, demand is large sensor type, is widely used in the field such as industrial and agricultural production, Chemical Manufacture.RFID label chip can identify the information of destination object, but it can not obtain the pressure information residing for it.
Summary of the invention
Object of the present invention is just to provide a kind of RFID label tag for chemical pump band pressure transducer to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes RFID circuit, antenna, pressure transducer and fluid sensitive switch, the first end of described antenna is connected with the first signal output part of described RFID circuit, described pressure sensor signal output terminal is connected with the pressure signal input end of described RFID circuit, the first end of described fluid sensitive switch is connected with the secondary signal output terminal of described RFID circuit, and the second end of described fluid sensitive switch is connected with the second end of described antenna.
Particularly, described fluid sensitive switch comprises cable, ball float shell and microswitch, described microswitch is arranged in described ball float shell, described cable is connected with described microswitch, through hole and steel ball is provided with in described microswitch, described steel ball is placed in described through hole, and described cable is placed in the one end in described through hole.
Beneficial effect of the present invention is:
The present invention transforms on the basis of existing RFID label tag, add pressure transducer and switch, form a RFID label tag can measuring pressure improved, solve the pressure monitor of each point in chemical pump, decrease artificial error, full extend RFID label tag function, makes RFID technique have a wide range of applications in chemical industry simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of RFID label tag of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
The present invention includes RFID circuit 2 and antenna 4, the first end of antenna 4 is connected with the first signal output part of RFID circuit 2, also comprise pressure transducer 3 and fluid sensitive switch 5, pressure transducer 3 signal output part is connected with the pressure signal input end of RFID circuit 2, the first end of fluid sensitive switch 5 is connected with the secondary signal output terminal of RFID circuit 2, second end of fluid sensitive switch 5 is connected with the second end of antenna 4, fluid sensitive switch 5 comprises cable 6, ball float shell 8 and microswitch 7, microswitch is arranged in ball float shell 8, cable 6 is connected with microswitch 7, through hole and steel ball 9 is provided with in microswitch 7, steel ball 9 is placed in through hole, cable 6 is placed in the one end in through hole.Particularly, fluid sensitive switch 5 utilizes microswitch 7 to do contact to export, when surface level and the line angle degree that raises up are more than 10 °, the steel ball 9 of floating-ball level switch 5 inside can roll and is pressed onto microswitch 7 or departs from microswitch 7, and fluid sensitive switch 5 contact point signal that is closed or that disconnect is exported.When fluid sensitive switch 5 is in off-state, RFID circuit 2 follows the antenna 4 be connected with RFID circuit 2 to be in off state, and label 1 can not work; When fluid sensitive switch 5 is in closure state, RFID circuit 2 follows the antenna 4 be connected with RFID circuit 2 to be in normal condition, and label 1 normally can experience pressure, receives and transmits.
