Detailed Description

Referring to fig. 1 and 2, a monitoring and management system using passive Radio Frequency Identification (RFID) according to the present invention includes a passive tag module 1, a reader 2 and a management module 3. The tag module 1 is internally provided with an integrated circuit 11 including a coil 12 as an antenna for receiving and emitting electromagnetic waves. The label module 1 has a plurality of monitor chips 13A-13D respectively connected to a monitored device 4A-4D, and each monitor chip 13A-13D can determine whether to electrically connect to the integrated circuit 11 according to the state of the corresponding device 4A-4D. The tag module 1 is not provided with a power supply inside, when the coil 12 receives an external electromagnetic wave, a current is generated based on an electromagnetic effect, and the integrated circuit 11 is driven, and at this time, the monitoring chips 13A to 13D electrically connected to the integrated circuit 11 generate an electrical signal, and further generate an electromagnetic wave through the coil 12 to be emitted outwards.

The electromagnetic wave received by the coil 12 is emitted from the reader 2. The electromagnetic wave emitted by the reader 2 within a certain distance range of the tag module 1 will generate current after being received by the coil 12, and further drive the integrated circuit 11, and the electrical signal generated by each monitoring chip 13A-13D will generate electromagnetic wave through the coil 12 to be emitted outwards, and the electromagnetic wave will be received by the reader 2. The reader 2 is electrically connected with a management module 3, and transmits the received information to the management module 3, so that the management module 3 can know the state of each monitored device 4A-4D, and further integrate the information.

The utility model discloses all can realize in multiple application. Fig. 3 shows a first embodiment of the present invention, which is an application example of the liquid level meter. In this embodiment, a liquid level meter 51 is disposed in a liquid container, and includes a floating ball 52 floating on the liquid level and moving along with the liquid level, wherein a magnet is disposed on the floating ball 52. In addition, a plurality of reeds 53A-53D are provided at different depths in the container, which represent high, medium, low, and low water level indicators, respectively, and are connected with the monitor chips 13A-13D in the label module 1 in a one-to-one manner. When the floating ball comes to any one of the reeds (in this case, the reed 53C) along the liquid surface, the reed 53C is attracted by the magnet of the floating ball 52 to generate a change, which may be a rotation or movement of a physical property, or an electromagnetic induction of an electromagnetic property, etc., and further electrically connects the corresponding monitoring chip 13C to the integrated circuit 11. On the other hand, the other reeds 53A, 53B, 53D not attracted by the float ball 52 disconnect the corresponding monitor wafers 13A, 13B, 13D from the integrated circuit 11.

Accordingly, when the engineer operates the reader to transmit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates current, and then the monitoring chip 13C is turned on, so that the monitoring chip 13C generates an electrical signal, and the electrical signal is converted into electromagnetic waves through the coil 12 again and transmitted back to the reader. After the reader sends this message back to the management module, the management module can know that the liquid level of the liquid container is at the low level represented by the reed 53C.

Fig. 4 shows a second embodiment of the present invention, which is an application example of the pressure gauge. In the present embodiment, one pressure gauge 6A to 6D is provided for each of the plurality of pressure vessels, and the pressure value of each vessel is displayed by the pointer 61. Each of the pressure gauges 6A to 6D is provided with a monitoring area 62 in a partial area, for example, a low pressure area or a high pressure area, according to the requirement, and a sensing element 63 is provided at the end of the indicating needle 61. The pressure gauges 6A to 6D are connected one-to-one to monitor wafers 13A to 13D in the label module 1. When the pointer 61 of each pressure gauge 6A-6D swings to the monitoring area 62 (in this case, the pressure gauge 6A) according to the pressure of the corresponding container, the sensing element 63 generates a signal, so that the corresponding monitoring chip 13A is electrically connected to the integrated circuit 11; the pressure gauges 6B to 6D whose hands are not swung to the monitoring area disconnect the corresponding monitor wafers 13B to 13D from the integrated circuit 11.

Accordingly, when the engineer operates the reader to transmit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates current, and then the monitoring chip 13A is turned on, so that the monitoring chip 13A generates an electric signal, and the electric signal is converted into the electromagnetic waves through the coil 12 again and transmitted back to the reader. After the reader sends this message back to the management module, the management module can know that the pressure of the pressure vessel in which the pressure gauge 6A is located is in a low pressure state, and the other pressure vessels are not in a low pressure state.

Fig. 5 shows a third embodiment of the present invention, which is applied to switch monitoring of a plurality of electrical appliances. In this embodiment, a switch 7A-7D is disposed on each of the plurality of electrical appliances for controlling the on/off of each electrical appliance. The switches 7A to 7D are connected to the monitor chips 13A to 13D in the tag module 1 one-to-one. When the switches of the electrical devices are in an off state (in this example, the switch 7A is in an on state, and the switches 7B to 7D are in an off state), the corresponding monitor chips 13B to 13D are electrically connected to the integrated circuit 11; the switch 7A in the on state disconnects the corresponding monitor wafer 13A from the integrated circuit 11.

Accordingly, when the engineer operates the reader to transmit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates current, and then the monitoring chips 13B to 13D are turned on, so that the monitoring chips 13B to 13D generate an electric signal, and the electric signal is converted into electromagnetic waves through the coil 12 again and transmitted back to the reader. After the reader sends the message back to the management module, the management module can know that the electrical appliances of the switches 7B-7D are in the off state and the electrical appliance of the switch 7A is in the on state.

Fig. 6 shows a fourth embodiment of the present invention, which is used for monitoring whether a safety pin is actually inserted into a plurality of objects. In this embodiment, a plurality of objects with potential leakage caused by erroneous touch are respectively provided with a safety latch 8A-8D for preventing the erroneous touch from starting. The security pins 8A to 8D are connected to the monitor chips 13A to 13D in the tag module 1 one-to-one. When each safety pin is in a falling state (in this example, the safety pin 8A is in a falling state, and the safety pins 8B to 8D are in a true insertion state), the corresponding monitoring chip 13A is electrically connected to the integrated circuit 11; the safety pins 8B to 8D in the inserted state disconnect the corresponding monitor chips 13B to 13D from the integrated circuit 11.

Accordingly, when the engineer operates the reader to transmit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates current, and then the monitoring chip 13A is turned on, so that the monitoring chip 13A generates an electric signal, and the electric signal is converted into the electromagnetic waves through the coil 12 again and transmitted back to the reader. After the reader sends the message back to the management module, the management module can know that the safety pin 8A falls off, and the safety pins 8B-8D are inserted.

Through the description of the foregoing embodiments, it can be understood that the present invention utilizes the tags of passive rfid technology to monitor a plurality of monitored devices, and can monitor the status of each device without setting up a power supply, and the engineer only needs to operate the reader when needing to know the status of each device, and can immediately and clearly obtain information, and integrate through the management module, thereby achieving the effect of continuous monitoring without energy consumption.

The above description is the preferred embodiment of the present invention and the technical principle applied by the same, and for those skilled in the art, without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention all belong to the protection scope of the present invention.
