[0033] The embodiment of the present invention provides a temperature control system. Figure 1 is a structural diagram of a temperature control system provided by an embodiment of the present invention, such as Figure 1 As shown, the temperature control system 100 includes a fan M, a sensor component 110, a control module 120 and a ventilation component 130, and the fan M, the sensor component 110, the control module 120 and the ventilation component 130 are installed on the outdoor cabinet; the sensor component 110 is used to collect the measured environmental parameters and output the measurement signal according to the measured environmental parameters; the control module 120 is connected to the sensor component 110, and the fan M is connected to the control module 120, and the control module 120 is used to detect the measurement signal, and when the measurement signal is greater than a first preset value, the fan M is controlled to start, and the fan M is used to drive the ventilation component 130 after starting; the control module 120 is also used to start timing when the measurement signal is less than or equal to the first preset value, and to turn off the fan M when the timing duration meets the first preset duration.

[0034] In this embodiment, the temperature control system 100 is a system for controlling and adjusting temperature, which can monitor and adjust the temperature of the environment or equipment through various sensors and actuators to ensure that the equipment operates within a set temperature range. The fan M increases the gas pressure and discharges the gas according to the input mechanical energy. For example, the fan M includes a ventilator, a blower, etc. The sensor assembly 110 is a component composed of sensitive elements, conversion elements, and signal processing circuits, etc., which can convert the collected physical quantities into electrical signals that are easy to be processed by humans or computers. The control module 120 is a module for data processing such as data reading and data transmission. The ventilation assembly 130 includes various components that constitute the ventilation system, for example, including air inlets, air outlets, etc.

[0035] In this embodiment, the sensor component 110 collects the measured environmental parameters inside and outside the outdoor cabinet. For example, the measured parameter is a temperature signal. The sensor component 110 outputs a measurement signal according to the temperature difference between the inside and outside of the outdoor cabinet. When the measurement signal is greater than the first preset value (that is, the temperature difference exceeds the set threshold), the control module 120 controls the fan M to start, and the fan M drives the ventilation component 130, and the ventilation component 130 dissipates heat to the outdoor cabinet. When the measurement signal is less than or equal to the first preset value (that is, the temperature difference does not exceed the set threshold), the control module 120 starts timing, and turns off the fan M when the timing duration meets the first preset duration, and the ventilation component 130 no longer dissipates heat to the outdoor cabinet.

[0036] The technical solution of this embodiment provides a temperature control system, in which the fan, sensor assembly, control module and ventilation assembly are installed on an outdoor cabinet; the sensor assembly collects the measured environmental parameters and outputs the measurement signal according to the measured environmental parameters, and the control module controls the fan to start and controls the fan to be shut down with delay, and the fan is used to drive the ventilation assembly after starting. The temperature control system can avoid fan failure by controlling the fan to be shut down with delay, and the control module controls the fan operation at the same time, which can realize automatic control of the fan. Compared with the air conditioning control circuit and the heat exchanger control circuit in the prior art, the control circuit of the temperature control system is simple in structure and easy to maintain, which solves the problem of complex structure and inconvenient maintenance of the temperature control system in the prior art.

[0037] Figure 2 is a circuit diagram of a temperature control system provided by an embodiment of the present invention, such as Figure 2 As shown, the control module 120 includes a monitoring unit and a starting unit, the monitoring unit is connected to the first power supply V1, the sensor assembly 110 and the fan M, the starting unit is connected to the second power supply V2, the monitoring unit and the fan M, the monitoring unit is used to monitor the measurement signal, and connect the fan M and the first power supply V1 when the measurement signal is greater than a first preset value, start timing when the measurement signal is less than or equal to the first preset value, the starting unit is used to start the fan, and turn off the fan when the timing duration of the monitoring unit meets the first preset duration.

[0038] In this embodiment, the monitoring unit is a unit that monitors the measurement signal output by the sensor assembly, and the starting unit is a unit that starts or shuts down the fan. On the basis of the above embodiment, when the monitoring unit detects that the measurement signal is greater than the first preset value, the fan M is connected to the first power supply, the starting unit connects the fan M and the second power supply V2, and the fan M starts and drives the ventilation assembly 130. When the monitoring unit detects that the measurement signal is less than or equal to the first preset value, the fan M is disconnected from the first power supply and the timing is started. When the timing duration meets the first preset duration, the starting unit disconnects the fan M and the second power supply V2, and the fan M is turned off.

[0039] Exemplarily, the sensor assembly 110 includes a temperature sensor, a smoke sensor and a hydrogen sensor. The temperature sensor is used to collect temperature signals, the smoke sensor is used to collect smoke concentration signals, and the hydrogen sensor is used to collect hydrogen concentration signals. The temperature sensor is used to collect the temperature inside and outside the outdoor cabinet, and the first preset value includes the threshold of the temperature difference between the inside and outside of the outdoor cabinet. The smoke sensor is used to collect the smoke concentration inside the outdoor cabinet, and the first preset value also includes the smoke concentration threshold inside the outdoor cabinet. The hydrogen sensor collects the hydrogen concentration inside the outdoor cabinet, and the first preset value also includes the hydrogen concentration threshold inside the outdoor cabinet. The monitoring unit determines whether the temperature difference, smoke concentration or hydrogen concentration is greater than the corresponding system setting threshold, and the starting unit controls the fan M to start and stop, so as to achieve the purpose of ventilation, cooling, energy saving and efficiency improvement.

[0040] Specifically, the monitoring unit includes a first switch QF1, a monitoring host P and a relay KT, wherein a first end of the first switch QF1 is connected to the positive electrode of the first power source V1, a second end of the first switch QF1 is connected to the first end of the monitoring host P, a second end of the monitoring host P is connected to a first end of the coil of the relay KT and a first end a of the fan M, a second end of the coil of the relay KT is connected to a second end b of the fan M and a negative electrode of the first power source V1. The starting unit includes a contactor KM and a fuse FU, a first end of the coil of the contactor KM is connected to a first end of the contact of the relay KT, a second end of the coil of the contactor KM is connected to a negative electrode of the second power source V2, a first end of the contact of the contactor KM is connected to a positive electrode of the second power source V2 and a second end of the contact of the relay KT, a second end of the contact of the contactor KM is connected to a first end of the fuse FU, a second end of the fuse FU is connected to a third end c of the fan M, and a second end b of the fan M is connected to a negative electrode of the second power source V2.

[0041] In this embodiment, the relay KT can be a power-off time relay. The power-off time relay is used for the contacts to act instantaneously when the coil is energized, and the contacts are in a delayed setting working state after the coil is de-energized. When the set delay is reached, the delayed contacts return to the initial state. The contactor KM is an intermediate relay that transmits intermediate signals in the control circuit. Referring to the above embodiment, the first switch QF1 is closed, the monitoring host P is connected to the sensor component, and when it is detected that the measurement signal is greater than the first preset value, the terminal COM and the terminal NO are connected, the first terminal a and the second terminal b of the fan M are connected to the first power supply V1, the coil of the relay KT is energized, the contacts of the relay KT are closed, the coil of the contactor KM is energized, the contacts of the contactor KM are closed, the third terminal c of the fan M is connected to the second power supply V2, and the fan M is started. When it is detected that the measurement signal is less than or equal to the first preset value, the terminal COM and the terminal NO are disconnected, the first end a and the second end b of the fan M are disconnected from the first power supply V1, the coil of the relay KT loses power and starts timing. When the timing duration of the relay KT meets the first preset duration, the contacts of the relay KT are disconnected, the coil of the contactor KM loses power, the contacts of the contactor KM are disconnected, the third end c of the fan M is disconnected from the second power supply V2, and the fan M is turned off. For example, the first preset duration is 30s. When the fan is still slowly stopping to zero speed, the second power supply and the third end c of the fan are directly disconnected, and the fan is at risk of burning out. By setting a power-off delay time relay, fan failure can be avoided.

[0042] Continue to refer Figure 2 The monitoring unit further includes a second switch QF2 and a lighting lamp HR, wherein a first end of the second switch QF2 is connected to the positive electrode of the first power source V1, a second end of the second switch QF2 is connected to the first end of the lighting lamp HR, and a second end of the lighting lamp HR is connected to the negative electrode of the first power source V1. When the second switch QF2 is closed, the lighting lamp HR is turned on, and lighting can be provided inside the outdoor cabinet.

[0043] Figure 3 is a physical picture of an outdoor cabinet provided by an embodiment of the present invention. Figure 4 is a cross-sectional view of an outdoor cabinet provided by an embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the ventilation assembly includes an air inlet assembly and an air outlet assembly. The air inlet assembly is installed on the door of the outdoor cabinet, and the air outlet assembly is installed on the top of the outdoor cabinet. The air inlet assembly and the air outlet assembly are driven by a fan. Air outlet means that the fan discharges the hot air inside the cabinet out of the cabinet through the air outlet assembly, and air intake means that when the fan is running, the air pressure inside the cabinet is reduced, and the natural cold air outside the cabinet enters the cabinet through the air inlet assembly. Among them, the cabinet door is provided with 8 air inlets, which can provide sufficient air intake.

[0044] Specifically, the air inlet assembly includes a filter A, a first louver B and a first damper C. The air outlet assembly includes a second damper D and a top compartment air outlet E, wherein the filter A and the first louver B in the air inlet assembly have a dual waterproof function, the first louver B is designed to be 45 degrees, and can block most of the water, the filter A has a dustproof and waterproof function, and the dustproof level is relatively high, the first damper C can also play a waterproof and dustproof role, and the second damper D has the functions of preventing insects, leaking cold air, and preventing water from flowing back. Referring to the above embodiment, when the fan M is started, the air pressure in the cabinet is reduced, prompting the first damper C and the second damper D to open, and the natural cold air enters from the first louver B, is filtered by the filter A for dust prevention, and then flows through the heating equipment inside the cabinet, and is drawn out by the fan to the top compartment air outlet E, and the top compartment air outlet E is downward to prevent rainwater from flowing back. When the fan M is turned off, the first damper C and the second damper D naturally droop and close, and the cabinet is isolated from the external environment, providing a closed environment for the standby refrigeration system.

[0045] The present invention also provides a control method, which is executed by the temperature control system in any of the above embodiments. Figure 5 is a flow chart of a control method provided by an embodiment of the present invention, such as Figure 5 As shown, the control method includes:

[0046] S10, the sensor component collects the measured environmental parameters and outputs a measurement signal;

[0047] S20, when the control module detects that the measurement signal is greater than a first preset value, the control module controls the fan to start;

[0048] S30, the fan drives the ventilation component after starting;

[0049] S40, the control module starts timing when it detects that the measurement signal is less than or equal to a first preset value, and turns off the fan when the timing duration meets the first preset duration.

[0050] In this embodiment, the sensor component collects the measured environmental parameters of the outdoor cabinet. For example, the measured environmental parameters are temperature signals. The sensor component outputs a measurement signal according to the temperature signal. When the measurement signal is greater than a first preset value, the control module controls the fan to start, and the fan drives the ventilation component, and the ventilation component dissipates heat to the outdoor cabinet. When the measurement signal is less than or equal to the first preset value, the control module starts timing, and turns off the fan when the timing duration meets the first preset duration, and the ventilation component 130 no longer dissipates heat to the outdoor cabinet. When the monitoring unit detects that the measurement signal is less than or equal to the first preset value, it disconnects the fan M from the first power supply and starts timing. When the timing duration meets the first preset duration, the starting unit disconnects the fan M and the second power supply V2, and the fan M is turned off.

[0051] For example, Figure 6 is a flow chart of another control method provided by an embodiment of the present invention, such as Figure 6As shown, the sensor component includes a temperature sensor, a smoke sensor and a hydrogen sensor. The temperature sensor collects the temperature inside and outside the outdoor cabinet, the smoke sensor collects the smoke concentration inside the cabinet, and the hydrogen sensor collects the hydrogen concentration. The measurement signal output by the sensor component is transmitted to the monitoring host. If the hydrogen concentration is greater than the set value, the temperature difference between the inside and outside of the cabinet is greater than the set value, or the smoke concentration is greater than the set value, the 12V fan control power supply (i.e., the first power supply) is powered on, the 48V fan starting power supply (i.e., the second power supply) is powered on, the first damper and the second damper are opened, the air duct flows, and the temperature difference between the inside and outside of the cabinet, the smoke concentration or the hydrogen concentration decreases. If the hydrogen concentration is not greater than the set value, the temperature difference between the inside and outside of the cabinet is not greater than the set value, and the smoke concentration is not greater than the set value, the 12V fan control power supply is powered off, and it is determined whether the 12V fan control power supply is powered off for more than 30S. When it is greater than 30S, the 48V fan starting power supply is powered off, the fan stops, the first damper and the second damper are closed, the air duct stops, and the temperature difference between the inside and outside of the cabinet, the smoke concentration or the hydrogen concentration increases.

[0052] The fan, ventilation components, and control module in the temperature control system provided in this embodiment work closely together. The control module can monitor and control the temperature, smoke concentration, and hydrogen concentration in real time, and can achieve remote control according to preset instructions to reduce on-site maintenance costs. The fan operation is controlled by the control module, and automatic control of the fan can be achieved. At the same time, compared with the temperature control system using air conditioning and heat exchangers, the cost of the fan is lower.

[0053] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0054] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
