[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] See also 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 thermostat 2, the first thermostat 2 being connected to the temperature control component 1 to control the temperature control component 1 to start or shut down; a second thermostat 3, the second thermostat 3 being connected to the temperature control component 1 to control the temperature control component 1 to start or shut down; and a temperature sensing module; wherein, when the first thermostat 2 stops working, the second thermostat 3 controls the temperature control component 1 to start or shut down according to the temperature detected by the temperature sensing module.

[0030] With the above arrangement, the temperature control system is controlled by setting two thermostats, one main and one backup. When the main thermostat (the first thermostat 2) fails, the backup thermostat (the second thermostat 3) can instantly replace the main thermostat to control the entire system, making the entire system run more stably and safely, and solving the technical problem of untimely maintenance of thermostats in related technologies.

[0031] See also Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes: a first relay 5, the first relay 5 is connected to the temperature control component 1; a first control circuit 10, the first relay 5 and the first thermostat 2 are both connected to the first control circuit 10, 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 is running through a first switch 101 provided on the first relay 5 , which has a simple structure and is easy to operate.

[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 thermostat 2 , and the first thermostat 2 controls the first switch 101 according to the temperature detected by the first thermocouple 41 .

[0034] Specifically, when it is detected that the temperature reaches 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 it is detected that the temperature does not reach 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 also Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes: a second relay 6, the second relay 6 is connected to the second thermostat 3; a second control circuit 20, the second control circuit 20 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 arrangement, 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 the operation of multiple thermostats, causing system confusion, 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 arranged 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 arrangement, when the first switch 101 closes the first relay 5, current passes through the first control circuit 10, while the second control circuit 20 is blocked. In this way, it can be ensured that when 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, with a simple structure and low cost.

[0039] See also Figures 1 to 5 In the temperature control system of this embodiment, the temperature control system includes a third control circuit 30, the third control circuit 30 is connected to the first control circuit 10, and 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, the third control circuit 30 is connected to the first control circuit 10, and the second thermostat 3 works. When the third control circuit 30 is turned off, the second thermostat 3 does not work. In this way, the second thermostat 3 can be controlled separately, thereby meeting more requirements.

[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 thermostat 3 ; the second thermostat 3 controls the second switch 301 according to the temperature detected by the second thermocouple 42 .

[0042] With the above arrangement, the second thermostat 3 controls the switch of the second thermostat 3 according to the temperature detected by the second thermocouple 42, so that when the first thermostat 2 is out of control, the second thermostat 3 can replace the function of the first thermostat 2, ensuring the normal operation of the temperature control system.

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

[0044] With the above arrangement, when the first indicator light 7 is on, it indicates that the first thermostat 2 has stopped working, which can serve as a reminder to the staff. When the second indicator light 8 is on, it indicates that the second thermostat 3 is working, which can serve as a reminder to the staff.

[0045] In the temperature control system of this embodiment, the temperature control component 1 is a heater. The above arrangement constitutes a heating system, so that when the temperature controller of the heating system is damaged, the heating system can be guaranteed to work normally.

[0046] The temperature control device of this embodiment includes a temperature control system, and the temperature control system is the temperature control system mentioned above.

[0047] With the above arrangement, the heating system is controlled by setting two thermostats, one main and one backup. When the main thermostat fails, the backup thermostat can instantly replace the main thermostat to control the entire system, making the entire system run more stably and safely.

[0048] The control method of this embodiment is applicable to the above-mentioned temperature control system, and 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 thermostat 2 is normal; if the first thermostat 2 is abnormal, turning on the second thermostat 3; if the first thermostat 2 is normal, not turning on the second thermostat 3.

[0049] With the above setting, two thermostats, one main and one backup, are set to control the heating system. When the main thermostat fails, the backup thermostat can instantly replace the main thermostat to control the entire system. When the main thermostat does not fail, the backup thermostat is not put into use, making the entire system run more stably and energy-saving.

[0050] In the control method of this embodiment, see Figure 5 The method for detecting whether the first thermostat 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, it is determined that the first thermostat 2 is abnormal.

[0051] The above arrangement can ensure that when the first thermostat 2 fails, the second thermostat 3 can replace the function of the first thermostat 2 .

[0052] Embodiment 1:

[0053] The temperature control system of this embodiment is mainly composed of two thermostats and two relays, wherein the thermocouples on the first thermostat 2 and the second thermostat 3 are placed at 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 to open and close by the first thermostat 2; the heating module is connected to the neutral and live wires through the first relay 5.

[0054] Embodiment 2:

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

[0056] The first step is to set the inductive resistance of the thermocouples of the first thermostat 2 and the second thermostat 3 to the corresponding resistance of the preset temperature and place them at the detection position;

[0057] The second step is to close the neutral and live wire switches, and the first thermostat 2 will be powered.

[0058] In the third step, the system starts to run. If the first thermostat 2 works normally, the second thermostat 3 is in a power-off state; if the first thermostat 2 fails, the second thermostat 3 will be activated to replace the first thermostat 2.

[0059] Embodiment three:

[0060] See also Figure 4 After the thermocouple is configured and the circuit is connected, the temperature control system of this embodiment will work according to the following steps:

[0061] The first step is to set the inductive resistance of the thermocouples of the first thermostat 2 and the second thermostat 3 to the corresponding resistance of the preset temperature and place them at the detection position;

[0062] The second step is to close the neutral and live wire switches, and the first thermostat 2 will be powered.

[0063] In the third step, after the first thermostat 2 is powered on, if the temperature of the detection part is lower than the set temperature, the RS of the first thermostat 2 will be closed, the first control circuit 10 loop will be closed, and the second control circuit 20 loop will be disconnected, causing the first relay 5 to be connected and the second relay 6 to be disconnected. The effect is that the heating module is powered on and starts to heat, and the second thermostat 3 loses power. If the first thermostat 2 fails at this time and causes the RS to be disconnected, the first control circuit 10 loop will be disconnected, the second control circuit 20 loop will be closed, and LED1 will light up, activating the second thermostat 3, and the RS of the second thermostat 3 will be closed, and the third control circuit 30 loop and the first control circuit 10 loop combination will be closed and LED2 will light up, ensuring that the first relay 5 continues to be closed and the heating module heats normally.

[0064] In the fourth step, after the first thermostat 2 is powered on, if the temperature of the detection part is greater than the set temperature, the RS of the first thermostat 2 will be disconnected, the second control circuit 20 loop is connected, LED 1 lights up, and the second thermostat 3 is powered on. However, because the temperature of the detection part is greater than the set temperature, it will remain disconnected, the heating module will not be powered on, and the temperature of the detection part will naturally drop.

[0065] Step 6. Under normal circumstances, when heated to the predetermined temperature, the RS of the first thermostat 2 is disconnected, the first control circuit 10 circuit is disconnected, the second control circuit 20 circuit is closed, and LED1 lights up. The RS of the second thermostat 3 is disconnected, the third control circuit 30 circuit is disconnected, the first relay 5 loses power, and the heating module loses power and shuts down. When the first thermostat 2 fails, its RS is disconnected, the first control circuit 10 circuit is disconnected, the second control circuit 20 circuit is closed, and LED1 lights up. The second thermostat 3 detects that the temperature has reached the predetermined temperature, its RS is disconnected, the third control circuit 30 circuit is disconnected, and the heating module loses power and shuts down.
