一种车载多蓄冷箱集中智能监控系统A centralized intelligent monitoring system for vehicle-mounted multiple cold storage boxes

技术领域technical field

 本发明涉及一种蓄冷箱温湿度监控系统，具体地讲，涉及一种车载多蓄冷箱集中智能监控系统。The present invention relates to a temperature and humidity monitoring system for a cold storage box, in particular to a centralized intelligent monitoring system for multiple cold storage boxes on a vehicle.

背景技术Background technique

用蓄冷箱运输产品，铁别是鲜活农产品时，需记录运输途中蓄冷箱温湿度对鲜活农产品品质的影响；了解冷藏运输车中不同位置的蓄冷箱，运输途中他们温湿度的不同变化。这都需要实时记录下多个蓄冷箱温湿度数据。When using cold storage boxes to transport products, especially fresh agricultural products, it is necessary to record the influence of temperature and humidity of cold storage boxes on the quality of fresh agricultural products during transportation; understand the different changes of temperature and humidity of cold storage boxes in different positions in refrigerated transport vehicles during transportation. This requires real-time recording of the temperature and humidity data of multiple cold storage boxes.

目前的温湿度监控系统大都是一台温湿度记录仪仅监控一个蓄冷箱，不能同时监控多个蓄冷箱，造成监控多个蓄冷箱时成本很高。目前的温湿度记录仪与温湿度传感器大都是一体的，维修更换不方便。温湿度监控系统都需要将监控数据传输给计算机，目前的温湿度监控系统，要么采用无线方式，要么采用有线方式。显然有线方式，对于车载的蓄冷箱，不太合适或很不方便，因为这要么需要一台车载计算机，要么必须将整个温湿度记录仪搬到计算机处。对于无线方式，一方面，无线发送多个蓄冷箱的温湿度实时数据，数据量大，能耗高通信费用高；另一方面，蓄冷箱的温湿度通常在规定的范围内，也没有必要实时发送给远程的计算机。Most of the current temperature and humidity monitoring systems use a temperature and humidity recorder to monitor only one cold storage box, and cannot monitor multiple cold storage boxes at the same time, resulting in high costs for monitoring multiple cold storage boxes. Most of the current temperature and humidity recorders and temperature and humidity sensors are integrated, which is inconvenient for maintenance and replacement. All temperature and humidity monitoring systems need to transmit monitoring data to the computer. The current temperature and humidity monitoring systems either use wireless or wired methods. Obviously, the wired method is not suitable or very convenient for the vehicle-mounted cold storage box, because it either requires an on-board computer, or the entire temperature and humidity recorder must be moved to the computer. For the wireless method, on the one hand, the real-time temperature and humidity data of multiple cold storage boxes are sent wirelessly, the data volume is large, the energy consumption is high, and the communication cost is high; on the other hand, the temperature and humidity of the cold storage boxes are usually within the specified range, and it is not necessary sent to a remote computer.

仅有基于zigbee或射频芯片的无线温湿度监控系统，可同时监控多个蓄冷箱，但zigbee或射频模块收发端都需要，成本很高；且车载环境，噪声大，无线通信很不稳定，能耗大；对控制器的能力要求高，成本高。他们同样在将监控数据传输给计算机时，存在上述的不适宜车载或者能耗高通信费用高的缺点。There are only wireless temperature and humidity monitoring systems based on zigbee or radio frequency chips, which can monitor multiple cold storage boxes at the same time. High consumption; high requirements on the capability of the controller and high cost. They also have the above-mentioned shortcomings of being unsuitable for vehicles or high energy consumption and high communication costs when transmitting monitoring data to computers.
