[0067] As an extension and refinement of the above embodiment, the present application provides another embodiment of the electric heating equipment monitoring system 100, referring to Figure 2 As shown, the electric heating equipment monitoring system 100 provided in this embodiment is Figure 1 The structure of the electric heating equipment monitoring system 100 provided in the embodiment shown is different in that: the electric heating equipment monitoring system 100 provided in this embodiment further includes a second temperature sensor 104, a fourth acquisition module 108, a fourth processing module 124 and a fourth alarm module 134. Figure 1 The same partial structures of the electric heating equipment monitoring system 100 provided in the illustrated embodiment will not be described in detail, and reference is made to the above description for details.

[0068] In some embodiments, the second temperature sensor 104 is located on the electric heating belt 110 and is used to monitor the second working temperature of the electric heating belt 110 in real time; the fourth processing module 124 is used to calculate the difference between the first working temperature and the second working temperature, and determine whether the absolute value of the difference is greater than the threshold difference. If so, the second temperature alarm information is output. For example, Figure 3 As shown, the first acquisition module 105 can be connected to the fourth acquisition module 108 .

[0069] In some embodiments, a fourth acquisition module 108 and a fourth alarm module 134; wherein: the fourth acquisition module 108 is respectively connected to the second temperature sensor 104 and the fourth processing module 124, for acquiring the second working temperature and transmitting the second working temperature to the fourth processing module 124; the fourth alarm module 134 is connected to the fourth processing module 124.

[0070] Exemplarily, the second temperature sensor 104 may be a thermistor. It should be noted that the second temperature sensor 104 may be a contact temperature sensor or a non-contact temperature sensor, as long as it can accurately measure the working temperature of the electric heating cable 110 .

[0071] Specifically, after the first acquisition module 105 acquires the first working temperature of the electric heating belt 110 monitored by the first temperature sensor 101, it transmits the data of the first working temperature to the fourth acquisition module 108. After the fourth acquisition module 108 acquires the second working temperature of the electric heating belt 110 monitored by the second temperature sensor 104, it transmits the data of the second working temperature and the data of the first working temperature to the fourth processing module 124. After receiving the data of the first working temperature and the data of the second working temperature, the fourth processing module 124 calculates the difference between the first working temperature and the second working temperature, and determines whether the absolute value of the difference is greater than the threshold difference. If so, it outputs the second temperature alarm information; the fourth alarm module 134 responds to the second temperature alarm information and issues an alarm prompt. It should be noted that the fourth alarm module can be a single sound alarm or a single light alarm, or a sound and light alarm. By setting up the second temperature sensor 104, not only can it continue to monitor as a backup sensor when the first temperature sensor 101 fails, but it can also calculate the difference between the first working temperature and the second working temperature, and determine whether the absolute value of the difference is greater than the threshold difference. If so, the two temperatures of the electric heating belt 110 are too high, that is, the heating belt 110 has a local heat failure. The operator can observe the second temperature alarm information based on the fourth alarm module 134 and the touch display screen 135, so as to promptly repair the local heat failure of the electric heating belt 110.

The data processing module 120, the programmable controller 140 and the alarm module 130 are all arranged in the electric heating equipment monitoring control box B.

[0074] As an extension and refinement of the above embodiments, the present embodiment provides a system 100a for equipment to be heated. The system 200 for equipment to be heated includes: the electric heating equipment monitoring system 100 provided in any of the above embodiments of the present application, the electric heating cable 110 and the body 110a of the equipment to be heated.

[0075] Exemplarily, the body 110a of the equipment to be heated may be a pipe.
