Embodiment 1
[0041] Such as figure 1 with figure 2 As shown, a cable joint wireless passive real-time temperature measurement sensor device in this embodiment includes a temperature sensor 1 and an antenna 2, and the temperature sensor 1 and the antenna 2 are embedded in the place through an epoxy resin 4 injection curing molding process. In the cable joint 3, the temperature sensor 1 is in contact with the wires in the cable joint 3, and the antenna 2 is fixed on the temperature sensor 1 and communicated with it. The cable joint 3 is connected to one end of the cable 5 and conducts with the wires in the cable 5 .
[0042] In the embodiment of the present invention, the temperature sensor and the antenna are embedded in the cable joint through the epoxy resin injection curing molding process, so that the temperature sensor is in contact with the wire in the cable joint, that is, the temperature sensor is directly in contact with the high-voltage end of the cable joint, and the temperatur...
Embodiment 2
[0053] A kind of temperature sensing system of the present embodiment comprises:
[0054] The temperature collector is used to send temperature acquisition signals, and is also used to receive and send temperature signals;
[0055] The temperature measuring and sensing device as described in Embodiment 1 is used to receive and process the temperature acquisition signal, obtain a temperature signal and send the temperature signal to the temperature collector;
[0056] The terminal device is used to receive and display the temperature signal sent by the temperature collector.
[0057] Every temperature response time T, the terminal device is also used to control the temperature sensor to send a temperature collection signal, and within the preset time after the temperature sensor sends the temperature collection signal, the terminal device does not receive the temperature signal, the terminal equipment sends out an alarm signal.
[0058] The terminal device is also used to com...
