The embodiment provides a control method of a refrigerating unit, which can remotely control the refrigerating unit, so that the abnormity of the refrigerating unit can be timely found and solved, and the damage of goods in the refrigerating unit is prevented.
As shown in fig. 1, the control method of the refrigerating unit includes the following steps:
and S1, receiving the monitoring information of the refrigerating unit in real time, and transmitting the monitoring information to the control panel and the remote control module.
The monitoring information includes temperature information and pressure information in a refrigerator case of the refrigerator unit. In step S1, the temperature sensor may be used to monitor the temperature information in the freezer compartment and transmit the real-time monitored temperature information to the control panel and the remote control module, and the pressure sensor may be used to detect the pressure information in the freezer compartment and transmit the real-time monitored pressure information to the control panel and the remote control module. Alternatively, the monitoring information of the refrigerating unit may be received by a receiving module, which may be a CAN bus.
And S2, displaying the monitoring information by the control panel.
After the control panel receives the monitoring information, the monitoring information is displayed, so that a driver can see the pressure and temperature conditions in the freezer at any time. For example, the control panel may be a touch display panel on a refrigerator car carrying a freezer unit, and an outer shell of the control panel is made of an acrylonitrile-butadiene-styrene copolymer material, which has the characteristics of high strength, good toughness and easiness in processing and forming. The control panel may be mounted on the right side of the refrigerated vehicle driver's cab, which may employ a liquid crystal touch screen. The control panel has functions of interface mode selection, set temperature adjustment, user setting, use information inquiry, standby mode and the like, and virtual touch keys. A physical power switch key and the like can be arranged on the left side of a display screen of the control panel, and operation setting and information query of each device in the refrigerating unit can be realized by arranging the virtual touch key and the physical power switch key.
And S3, the remote control module transmits the monitoring information to a remote server.
The remote control module transmits the received monitoring information to the remote server through the antenna, and the remote server can store or analyze the monitoring information so as to remotely control the temperature adjusting device or the pressure adjusting device.
S4, determining whether to provide control signals to a temperature adjusting device and a pressure adjusting device of the refrigerating unit through a control panel, if so, executing a step S5; if not, step S6 is executed.
When the control panel and the remote control module receive the monitoring information, it is not determined whether the driver operates the control panel, and therefore it is necessary to determine whether to provide a control signal to the temperature adjusting device and the pressure adjusting device of the refrigerating unit through the control panel. For example, when the control device of the refrigeration unit is just started, characters of "whether to provide a control signal through the control panel", "yes" and "no" may be displayed on the display panel, and the driver is prompted to pay attention to the selection of yes or no, and when the driver selects "yes", which indicates that the driver has the ability to handle the abnormality of the refrigeration unit, step S5 may be executed; if the driver selects "no", which indicates that the driver is unable to handle the abnormality of the refrigerating unit, step S6 may be executed.
And S5, providing control signals to the temperature adjusting device and the pressure adjusting device through the control panel.
When the control panel displays that the refrigerating unit is abnormal or has faults, the driver solves the abnormity of the refrigerating unit through the virtual key on the control panel.
And S6, providing control signals to the temperature adjusting device and the pressure adjusting device by the remote server according to the monitoring information.
The remote control module sends the monitoring information to the remote server, and after the driver selects 'no', the remote server analyzes and processes the monitoring information, if the temperature information is compared with the preset temperature information, the pressure information is compared with the preset pressure information, whether the refrigerating unit is abnormal or fails is determined, the abnormal equipment is remotely controlled, and then the refrigerating unit is ensured to recover to normal operation.
In the control method of the refrigerating unit provided by this embodiment, the monitoring information is transmitted to the control panel and the remote control module, then the monitoring information is displayed on the control panel, and the monitoring information is transmitted to the remote server by the remote control module, then, it is determined whether to provide a control signal to the refrigerating unit through the control panel, so as to determine to provide a control signal to the refrigerating unit through the control panel or the remote server.
Optionally, the monitoring information may include not only temperature information and pressure information, but also fault information. As shown in fig. 2, before step S4, the method for controlling a refrigeration unit further includes: s7, determining whether there is fault information in the monitoring information obtained in real time, if yes, executing step S6, that is, if it is determined that there is fault information in the monitoring information, not executing step S4, but directly executing step S6, that is, directly providing a control signal from the remote server to the refrigerating unit; if not, step S4 is executed, that is, if it is determined that the monitoring information does not include the fault information, step S4 needs to be executed to determine whether the control signal can be provided to the refrigeration unit through the control panel.
Further, when there is failure information in the monitoring information, a failed device is determined by the remote server according to the failure information in the monitoring information and a failure control signal is transmitted to the failed device to remove the failure of the failed device in step S6. When the monitoring information includes both temperature information, pressure information, and failure information, the remote server transmits a control signal to the temperature adjustment device and the pressure adjustment device, and also transmits a failure control signal to the failure device. The fault device comprises a compressor, a condenser, an evaporator, a temperature sensor or a pressure sensor and the like.
In this embodiment, after step S3, that is, after the remote control module transmits the monitoring information to the remote server, the method for controlling the refrigeration unit further includes storing, by the remote server, the received monitoring information so as to record parameters of the refrigeration unit and facilitate later checking, and when there is fault information in the monitoring information, the method may further determine a device that is prone to fault occurrence according to the fault information stored by the remote server and analyze the reason, so as to avoid at an initial stage of design, thereby providing a strong basis for improving quality of refrigeration unit products and improving design. For example, the fault rates of the refrigerating unit in the operation process can be determined according to the stored monitoring information, and therefore improvement of the refrigerating unit can be effectively improved.
Optionally, in step S1, after the receiving module receives the monitoring information in the refrigerating unit, the receiving module may classify, encode and compress the monitoring information to obtain one or more monitoring information groups, and then transmit the monitoring information groups to the control panel and the remote control module. After the monitoring information is compressed, the data space occupied by the monitoring information can be reduced, the transmission speed can be further improved, and the timeliness of the control method of the refrigerating unit is improved. For example, the detection information may be classified into temperature information and pressure information, and the fault information may be classified into one category.
