[0002] Thermostats, as a common temperature control device, are widely used in large residences, shopping malls, hotels, and various commercial and industrial sites for temperature control. Because thermostats are in a state of frequent on / off operation once put into use, they are prone to damage, thus requiring maintenance by personnel.

[0003] However, when the thermostat malfunctions, it requires timely repair by staff. The staff needs time to react after the thermostat malfunctions, making it difficult to repair immediately if a fault occurs during use, which affects daily work.

[0004] Therefore, existing technologies need further development. Summary of the Invention

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] See Figures 1 to 5 According to an embodiment of the present invention, a temperature control system is provided, comprising: a temperature control component 1; a first temperature controller 2 connected to the temperature control component 1 to control the temperature control component 1 to start or stop; a second temperature controller 3 connected to the temperature control component 1 to control the temperature control component 1 to start or stop; and a temperature sensing module; wherein, when the first temperature controller 2 stops working, the second temperature controller 3 controls the temperature control component 1 to start or stop according to the temperature detected by the temperature sensing module.

[0030] By adopting the above configuration, the temperature control system is controlled by setting up two thermostats, one main and one backup. When the main thermostat (the second thermostat 3) fails, the backup thermostat (the second thermostat 3) can instantly replace the main thermostat to control the entire system, making the entire system more stable and safer to operate, and solving the technical problem of untimely thermostat maintenance in related technologies.

[0031] See Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes: a first relay 5, which is connected to the temperature control component 1; a first control circuit 10, which is connected to both the first relay 5 and the first temperature controller 2, and the first relay 5 is provided with a first switch 101 for turning on or off the first control circuit 10.

[0032] Specifically, the first control circuit 10 supplies power to the temperature control component 1, and the first relay 5 controls whether the temperature control component 1 operates through the first switch 101 set on the first relay 5. The structure is simple and the operation is convenient.

[0033] In the temperature control system of this embodiment, see Figures 1 to 5 The temperature sensing module includes a first thermocouple 41 disposed on the first temperature controller 2. The first temperature controller 2 controls the first switch 101 according to the temperature detected by the first thermocouple 41.

[0034] Specifically, when the temperature is detected to have reached the predetermined value, the first relay 5 is triggered to turn off the first switch 101, thereby controlling the temperature control component 1 to stop working. When the temperature is detected to have not reached the predetermined value, the first relay 5 is triggered to close the first switch 101, thereby ensuring the normal operation of the temperature control system.

[0035] See Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes: a second relay 6, which is connected to the second thermostat 3; a second control circuit 20, which is connected to the first control circuit 10; the second control circuit 20 is connected to the second relay 6; when the first switch 101 closes the first relay 5, the second control circuit 20 is disconnected from the first control circuit 10.

[0036] With the above configuration, when the first switch 101 closes the first relay 5 and the first thermostat 2 is working, the second control circuit 20 is disconnected from the first control circuit 10, so that the second thermostat 3 is not powered, thereby avoiding multiple thermostats working and causing system chaos, and saving energy consumption.

[0037] In the temperature control system of this embodiment, see Figures 1 to 5 The temperature control system includes a control resistor 201, which is disposed on the second control circuit 20. When the first switch 101 closes the first relay 5, the control resistor 201 is used to block the current on the second control circuit 20.

[0038] With the above configuration, when the first switch 101 closes the first relay 5, the current flows through the first control circuit 10, while the second control circuit 20 is blocked. This ensures that when the first temperature controller 2 is working, the second control circuit 20 is disconnected from the first control circuit 10, so that the second temperature controller 3 is not powered. The structure is simple and the cost is low.

[0039] See Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes a third control circuit 30, which is connected to the first control circuit 10. The second temperature controller 3 is provided with a second switch 301 for controlling the third control circuit 30 to be turned on or off.

[0040] Specifically, a third control circuit 30 is provided. When the third control circuit 30 is turned on, it is connected to the first control circuit 10, and the second temperature controller 3 operates. When the third control circuit 30 is turned off, the second temperature controller 3 does not operate. In this way, the second temperature controller 3 can be controlled independently, thereby meeting more needs.

[0041] In the temperature control system of this embodiment, see Figures 1 to 5 The temperature sensing module includes a second thermocouple 42 disposed on the second temperature controller 3; the second temperature controller 3 controls the second switch 301 according to the temperature detected by the second thermocouple 42.

[0042] With the above settings, the second temperature controller 3 controls the switching of the second temperature controller 3 according to the temperature detected by the second thermocouple 42. Thus, when the first temperature controller 2 fails to control, the second temperature controller 3 can replace the function of the first temperature controller 2, ensuring the normal operation of the temperature control system.

[0043] See Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes: a first indicator light 7, which is disposed on the second control circuit 20; and a second indicator light 8, which is disposed on the third control circuit 30.

[0044] With the above settings, when the first indicator light 7 illuminates, it indicates that the first temperature controller 2 has stopped working, which serves as a reminder to the staff. When the second indicator light 8 illuminates, it indicates that the second temperature controller 3 is working, which also serves as a reminder to the staff.

[0045] In the temperature control system of this embodiment, the temperature control component 1 is a heater. This configuration constitutes a heating system, ensuring normal operation of the heating system even if the temperature controller fails.

[0046] The temperature control device in this embodiment includes a temperature control system, which is the temperature control system described above.

[0047] By adopting the above configuration, the heating system is controlled by two thermostats, one main and one backup. When the main thermostat fails, the backup thermostat can instantly take over the control of the entire system, making the entire system more stable and safer to operate.

[0048] The control method of this embodiment is applicable to the temperature control system described above. The control method includes: detecting whether the temperature control component 1 is closed; when the temperature control component 1 is closed, detecting whether the first temperature controller 2 is normal; if the first temperature controller 2 is not normal, then turning on the second temperature controller 3; if the first temperature controller 2 is normal, then not turning on the second temperature controller 3.

[0049] With the above setup, two thermostats, one primary and one backup, are used to control the heating system. The backup thermostat can instantly take over the control of the entire system when the primary thermostat fails. When the primary thermostat is working properly, the backup thermostat is not used, making the entire system more stable and energy-efficient.

[0050] In the control method of this embodiment, see Figure 5 The method for detecting whether the first temperature controller 2 is normal includes: using the temperature sensing module to detect the temperature; if the temperature detected by the temperature sensing module is lower than the preset temperature, then the first temperature controller 2 is determined to be abnormal.

[0051] By adopting the above settings, it can be ensured that when the first thermostat 2 fails, the second thermostat 3 can replace the function of the first thermostat 2.

[0052] Example 1:

[0053] The temperature control system in this embodiment mainly consists of two thermostats and two relays. The thermocouples on the first thermostat 2 and the second thermostat 3 are placed on the same detection end. The first thermostat 2 is directly powered by the neutral and live wires. The second thermostat 3 is powered by the neutral and live wires through the second relay 6, and the second relay 6 is controlled by the first thermostat 2 to open and close. The heating module is connected to the neutral and live wires through the first relay 5.

[0054] Example 2:

[0055] The control method of the temperature control system in this embodiment is as follows:

[0056] The first step is to set the sensing resistance of the thermocouples of the first temperature controller 2 and the second temperature controller 3 to the corresponding resistance value of the preset temperature, and place them at the detection point.

[0057] The second step is to close the neutral and live wire switch, which will energize the first thermostat 2.

[0058] Third, the system starts running. If the first thermostat 2 is working normally, the second thermostat 3 is in a power-off state; if the first thermostat 2 malfunctions, the second thermostat 3 will be activated to take over the work of the first thermostat 2.

[0059] Example 3:

[0060] See Figure 4 In this embodiment, once the thermocouples are configured and the circuit connections are complete, the temperature control system will operate according to the following steps:

[0061] The first step is to set the sensing resistance of the thermocouples of the first temperature controller 2 and the second temperature controller 3 to the corresponding resistance values ​​of the preset temperature, and place them at the detection point.

[0062] The second step is to close the neutral and live wire switch, which will energize the first thermostat 2.

[0063] Thirdly, after the first temperature controller 2 is energized, if the temperature of the detection unit is lower than the set temperature, the RS switch of the first temperature controller 2 will close, the first control circuit 10 will close, and the second control circuit 20 will open, causing the first relay 5 to connect and the second relay 6 to disconnect. The effect is that the heating module is energized and begins heating, while the second temperature controller 3 is de-energized. If the first temperature controller 2 malfunctions at this time, causing the RS switch to open, the first control circuit 10 will open, the second control circuit 20 will close, LED1 will light up, activating the second temperature controller 3. The RS switch of the second temperature controller 3 will close, the combination of the third control circuit 30 and the first control circuit 10 will close, LED2 will light up, ensuring that the first relay 5 remains closed, and the heating module heats normally.

[0064] Fourth step: After the first temperature controller 2 is powered on, if the temperature of the detection unit is greater than the set temperature, the RS of the first temperature controller 2 will be disconnected, the second control circuit 20 will be connected and LED1 will light up, the second temperature controller 3 will be powered on, but because the temperature of the detection unit is greater than the set temperature, it will also remain disconnected, the heating module will not be powered on, and the temperature of the detection unit will naturally drop.

[0065] Step 6: Under normal circumstances, once the predetermined temperature is reached, the RS switch of the first temperature controller 2 disconnects, the first control circuit 10 disconnects, the second control circuit 20 closes, and LED1 illuminates. The RS switch of the second temperature controller 3 disconnects, the third control circuit 30 disconnects, the first relay 5 loses power, and the heating module shuts down. When the first temperature controller 2 malfunctions, its RS switch disconnects, the first control circuit 10 disconnects, the second control circuit 20 closes, LED1 illuminates, the second temperature controller 3 detects that the predetermined temperature has been reached, its RS switch disconnects, the third control circuit 30 disconnects, and the heating module shuts down.
