[0045] The technical solution of the present utility model will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0046] In one embodiment, a multi-link control system for a cold storage is provided. Please refer to Figure 1 , which includes: a pre-module 1 and a control module 2. The pre-module 1 and the control module 2 are arranged at different positions. The pre-module is arranged at a first position; the control module is arranged at a second position, and the distance between the second position and the cold storage is farther than the distance between the first position and the cold storage. The pre-module 1 can realize the control of the refrigeration device 3 of the cold storage.

[0047] However, whether the front-end module can control the refrigeration device is subject to the control of the control module. The control module 2 is communicatively connected to the front-end module 1 and is used to control the front-end module 1 to switch between a first state and a second state. When switched to the first state, the front-end module connects to the refrigeration device of the cold storage and can control the refrigeration device of the cold storage. When switched to the second state, the front-end module disconnects from the refrigeration device of the cold storage and cannot control the refrigeration device of the cold storage. The control module is also used to control the refrigeration device 3 of the cold storage.

[0048] Implementably, the first position can be located around the cold storage. For example, the front-end module 1 can be installed on the wall of the cold storage door or on the cold storage door. The control module 2 can be installed in the machine room.

[0049] Implementably, the front-end module can include: an operation unit 11 and a control unit 12. Please refer to Figure 2 ; The operation unit is connected to the control unit, and the control unit is directly or indirectly communicatively connected to the refrigeration device. By operating on the operation unit, the refrigeration device can be controlled through the control unit. The operation unit can be in the form of an operation screen or in the form of operation buttons.

[0050] Implementably, the control of the state of the front-end module can be achieved by a controllable switch provided in the front-end module. The controllable switch can be set between the operation unit and the control unit, such as Figure 2 the a position in, or can be set between the control unit and the refrigeration device, such as Figure 2 the b position in, or both positions can be set, as long as the connection between the front-end module and the refrigeration device can be controlled. Whether the connection between the operation unit and the control unit is disconnected or the connection between the control unit and the refrigeration device is disconnected, the front-end module cannot control the refrigeration device. In the first state, the controllable switch is turned on, making the connections between the operation unit, the control unit and the refrigeration device connected. In the second state, the controllable switch is turned off, making the connections between the operation unit, the control unit and the refrigeration device disconnected.

[0051] Implementably, the control module can control the state of the front-end module by means of a remote switch provided on the control module. The remote switch is located at one position and can control the front-end module to switch to the first state; when the remote switch is switched to another position, it can control the front-end module to switch to the second state. The remote switch can be a rotary remote switch or a left-right toggle switch. By selecting a position-switching type remote switch, the state of the front-end module can be judged by the position of the remote switch, which facilitates the understanding of the state.

[0052] Of course, in different embodiments, the control module can also control the state of the front-end module through a chip integrated in the control module, and can realize the switching between the first state and the second state of the front-end module through different inputs.

[0053] When the front-end module switches to the first state, not only can the control module set at the second position be used to control the refrigeration device, but also the front-end module set at the first position can be used to control the refrigeration device, realizing the linkage control of the control module and the front-end module.

[0054] In addition, the control module can control the state of the front-end module, and can open or close its control function, which is convenient for management.

[0055] The control of the refrigeration device by the front-end module can include the adjustment of the refrigeration device, such as the adjustment of temperature, etc.; it can also include the opening and closing of the refrigeration device. The control of the refrigeration device by the control module can also include the adjustment of the refrigeration device and can also include the opening and closing of the refrigeration device.

[0056] In one embodiment, the front-end module 1 further includes: a status indicator light, please refer to the figure, which is used to indicate whether the front-end module is in the first state or the second state.

[0057] Implementably, the status indicator light can indicate the first state and the second state in the form of on and off; it can also indicate the first state and the second state in the form of different colors.

[0058] In one embodiment, the multi-linkage control system of the cold storage further includes: a warehouse temperature probe 4, which can be set in the warehouse and is used to collect the temperature of the cold storage and upload it to the front-end module 1, please refer to Figure 3 . The front-end module can also transmit the temperature to the control module or transmit the temperature to the control module after processing it, which is convenient for the control module to also understand the temperature in real time. The reception of the temperature by the front-end module can be realized through a central processor 13, and this central processor can also realize the processing of the temperature. The control unit can also be integrated in this central processor, please refer to Figure 4 , for example, it can be realized through the same chip, such as: 1#NF8835.

[0059] In one embodiment, the front-end module includes a communication unit 14, please refer to Figure 5 , which can realize the communication between the control module and the front-end module, such as: the control module's control of the state switching of the front-end module, the transmission of information such as temperature from the front-end module to the control module. The communication unit can be realized by a communication chip, such as: RS485.

[0060] In addition, the connection between the front-end module and the refrigeration device can also be realized through a communication unit, which is not shown in the figure.

[0061] In addition, the control signal of the controllable switch of the front-end module by the control module can also be transmitted through the communication unit, which is not shown in the figure.

[0062] In one embodiment, multiple library temperature probes can be provided, and the temperatures of multiple library temperature probes can be averaged, resulting in more accurate results; moreover, when one of the library temperature probes fails, the other library temperature probes can still continue to work, and it is still convenient to understand the temperature of the cold storage, with a low failure rate.

[0063] In one embodiment, the front-end module further includes: a temperature display for displaying the temperature.

[0064] Implementably, the displayed temperature can be the temperature directly transmitted by the library temperature probe. When there are multiple library temperature probes, the displayed temperatures can also be multiple. The user can make their own judgments based on the multiple temperatures. For example, when the multiple temperatures are basically the same and meet the expectations, it indicates that the temperature is accurate; when the multiple temperatures vary greatly, it is possible that a library temperature probe has failed and can be checked.

[0065] In different embodiments, the displayed temperature can also be the processed temperature. For example, when there are multiple library temperature probes, the average value of the multiple temperatures can be displayed, so that the given temperature is more accurate.

[0066] In one embodiment, the control module further includes: an emergency stop module and a fault indication module. The emergency stop module is used to control the opening and closing of the control module; the fault indication module is used to give an indication when the control module fails.

[0067] In one embodiment, the front-end module can further include: a power switch for connecting or disconnecting the power supply of the front-end module. After the power supply is disconnected, even if the front-end module is in the first state, it is impossible to control the refrigeration device.

[0068] In one embodiment, the front-end module can further include: a heater for heating the front-end module to prevent it from condensing in a low-temperature environment and ensuring the safe use of internal electrical components.

[0069] The multi-link control system of the cold storage in the above embodiments can be applied to a food cold storage. Since the goods in the cold storage need to be taken in and out daily, the dual control operation of the refrigeration device allows the operator to switch the cold storage on and off at any time by using the front-end module around the cold storage, saving the time cost of the journey and improving the labor efficiency; reducing the opening duration of the cold storage and saving electricity energy consumption.

[0070] The utility model mainly provides a multi-link control system for a cold storage with an improved structure, where each part can be realized through circuits or electronic devices, and the software part that may be involved during the use process is not an improvement of the utility model.

[0071] In the description of this specification, the descriptions referring to terms such as "an implementation manner", "an embodiment", "a specific implementation process", "an example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the utility model.
