The one shown is a monitoring and management system using passive radio frequency identification (RFID) technology provided by the present invention, which includes a passive tag module 1, a reader 2, and A management module 3. An integrated circuit 11 is provided inside the tag module 1, including a coil 12 as an antenna for receiving and emitting electromagnetic waves. The label module 1 is equipped with a plurality of monitoring chips 13A ~ 13D, respectively connected to a monitored device 4A ~ 4D, each monitoring chip 13A ~ 13D can be determined according to the state of the corresponding device 4A ~ 4D electrical Connect the integrated circuit 11. There is no power supply inside the label module 1. When the coil 12 receives electromagnetic waves from the outside, it will generate current based on the electromagnetic effect, which can then drive the integrated circuit 11, which is electrically connected to the integrated circuit 11 at this time. The monitoring chips 13A~13D will generate an electrical signal, and further generate an electromagnetic wave through the coil 12 and send it out.

The electromagnetic wave received by the coil 12 is emitted by the reader 2. The electromagnetic wave emitted by the reader 2 within a certain distance of the tag module 1 is received by the coil 12 and generates a current, which then drives the integrated circuit 11, and the telecommunications generated by each monitor chip 13A~13D The signal will generate electromagnetic waves through the coil 12 and send them out, which will be received by the reader 2. The reader 2 is electrically connected to a management module 3 to transmit the received information to the management module 3 so that the management module 3 can know the status of each monitored device 4A-4D , And achieve the effect of further integrating information.

The invention can be realized in various application fields. As shown in Figure 3, it is the first embodiment of the present invention, which is an application example of a level gauge. In this embodiment, a liquid level gauge 51 is provided in a liquid container, including a floating ball 52 that floats on the liquid surface and can move with the height of the liquid surface, wherein a magnet is provided on the floating ball 52. In addition, there are a plurality of reeds 53A~53D at different depths in the container, representing high, medium, low, and low water level marks, and they are one-to-one with the monitoring chip 13A~13D in the label module 1. connection. When the floating ball comes to any reed with the liquid surface (reed 53C in this example), the reed 53C will change when attracted by the magnet of the floating ball 52. The change can be physical Rotation or movement of nature, or electromagnetic induction of electromagnetic nature, etc., which can further electrically connect the corresponding monitoring chip 13C to the integrated circuit 11. On the other hand, other reeds 53A, 53B, and 53D that are not attracted by the floating ball 52 disconnect the corresponding monitoring chips 13A, 13B, and 13D from the integrated circuit 11.

Accordingly, when the engineer operates the reader to emit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates a current, which then turns on the monitoring chip 13C, so that the monitoring chip 13C generates an electrical signal and transmits it again The coil 12 converts the electrical signal into electromagnetic waves and transmits it 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 water level represented by the reed 53C.

Figure 4 shows the second embodiment of the present invention, which is an application example of a pressure gauge. In this embodiment, a pressure gauge 6A to 6D is respectively provided on the multiple pressure vessels, and the pressure value of each vessel is displayed through the pointer 61. Each pressure gauge 6A to 6D is provided with a monitoring area 62 in some areas according to requirements, such as a low pressure area or a high pressure area, and a sensing element 63 is provided at the end of the pointer 61. The pressure gauges 6A to 6D are connected to the monitoring chips 13A to 13D in the label module 1 one to one. When the pointer 61 of each pressure gauge 6A-6D swings to the monitoring area 62 (in this example, the pressure gauge 6A) according to the pressure of the corresponding container, the sensing element 63 generates a signal, which in turn causes the corresponding monitoring chip 13A to be electrically connected. It is connected to the integrated circuit 11; and the pressure gauges 6B-6D whose pointer does not swing to the monitoring area disconnect the corresponding monitoring chips 13B～13D from the integrated circuit 11.

According to this, when the engineer operates the reader to emit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates a current, which then turns on the monitoring chip 13A, so that the monitoring chip 13A generates an electrical signal and transmits it again The coil 12 converts the electrical signal into electromagnetic waves and transmits it back to the reader. After the reader transmits this information back to the management module, the management module can know that the pressure of the pressure vessel where the pressure gauge 6A is located is in a low pressure state, while other pressure vessels are not in a low pressure state.

Figure 5 shows the third embodiment of the present invention, which is applied to the on-off monitoring of multiple electrical appliances. In this embodiment, a switch 7A-7D is respectively provided on a plurality of electrical appliances to control the opening and closing of each electrical appliance. The switches 7A to 7D are connected to the monitoring chips 13A to 13D in the tag module 1 one to one. When the switches of the electrical appliances are in the off state (in this example, the switch 7A is in the on state, and the switches 7B to 7D are in the off state), the corresponding monitoring chips 13B to 13D are electrically connected to the integrated circuit 11; The switch 7A in the open state disconnects the corresponding monitoring chip 13A from the integrated circuit 11.

Accordingly, when the engineer operates the reader to emit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates a current, which then turns on the monitoring chips 13B to 13D, so that the monitoring chips 13B to 13D generate an electrical signal , And again through the coil 12 to convert the electrical signal into electromagnetic waves and transmit back to the reader. After the reader sends this message back to the management module, the management module can know that the electrical system where the switches 7B-7D are located is in the off state, and the electrical device where the switch 7A is located is in the on state.

Figure 6 shows the fourth embodiment of the present invention, which is used to monitor whether the safety pins of a plurality of objects are actually inserted. In this embodiment, a safety plug 8A-8D is respectively provided on a plurality of objects with the possibility of accidental touch and leakage to prevent accidental activation. The safety pins 8A to 8D are connected to the monitoring chips 13A to 13D in the label module 1 one to one. When each safety plug is in the off state (in this example, the safety plug 8A is in the off state, and the safety plugs 8B to 8D are in a positively inserted state), then the corresponding monitoring chip 13A is electrically connected to the integrated circuit 11; The safety pins 8B-8D that are in a positively inserted state disconnect the corresponding monitoring chips 13B-13D from the integrated circuit 11.

According to this, when the engineer operates the reader to emit electromagnetic waves to the tag module 1, the coil 12 receives the electromagnetic waves and generates a current, which then turns on the monitoring chip 13A, so that the monitoring chip 13A generates an electrical signal and transmits it again The coil 12 converts the electrical signal into electromagnetic waves and transmits it back to the reader. After the reader sends this message back to the management module, the management module can know that the safety pins 8A are off, and the safety pins 8B to 8D are indeed inserted.
