图1为传统大棚的温控方式，其中1为大棚结构框架，框架外部有主热源6为整个大棚进行加热，框架上有结构7，结构7为通风装置，对大棚内部的空气进行置换，结构2为温度传感器，结构3为大棚的加热管路，结构4和5为整个大棚加热的管路进出口装置，传统大棚的加热方式为当温度计检测到大棚的温度低于农作物适宜生长所需的温度时，人工启动或者自动启动加热装置，对整个大棚进行加热，此时主热源产生的热量通过介质，如热水或者蒸汽或者空气，通过送热管路进行到大棚中，对整个大棚进行加热，使大棚内温度达到或者维持在农作物适宜生长的温度，其具有明显的缺点，温度检测装置往往设置一个，分布在大棚的边缘或者大棚中心位置，不能够对大棚整体的温度进行有效反映，而且其加热时，需对整个大棚进行加热，可能有些局部温度已经过高，但是还存在继续加热的情况，会导致农作物受损，而且需要主热源长时间进行工作，造成能源的消耗和费用的增加。Figure 1 shows the temperature control method of a traditional greenhouse, in which 1 is the structural frame of the greenhouse, and there is a main heat source 6 outside the frame to heat the entire greenhouse. There is a structure 7 on the frame, and the structure 7 is a ventilation device, which replaces the air inside the greenhouse. The structure 2 is a temperature sensor, structure 3 is the heating pipeline of the greenhouse, and structures 4 and 5 are the pipeline inlet and outlet devices for heating the entire greenhouse. The heating method of the traditional greenhouse is when the thermometer detects that the temperature of the greenhouse is lower than the temperature required for the suitable growth of crops. When the temperature is high, manually start or automatically start the heating device to heat the entire greenhouse. At this time, the heat generated by the main heat source passes through the medium, such as hot water or steam or air, and enters the greenhouse through the heat delivery pipeline to heat the entire greenhouse. Making the temperature in the greenhouse reach or maintain the temperature suitable for the growth of crops has obvious disadvantages. One temperature detection device is often installed and distributed at the edge of the greenhouse or at the center of the greenhouse, which cannot effectively reflect the overall temperature of the greenhouse. When heating, the entire greenhouse needs to be heated, and some local temperatures may be too high, but there is still a situation of continuing heating, which will cause damage to the crops, and the main heat source needs to work for a long time, resulting in increased energy consumption and cost.
本发明的方案为分段测量温度和分段控制热源，从而实现对大棚分段式控制，其结构图如图2所示，其中1为大棚结构框架，6为主热源，负责为整个大棚提供热量来源，7为通风装置，负责为大棚进行换气，2为温度传感器，大棚被分为多个区域，每个区域根据农作物的种植的疏密程度，布置温度传感器2，每个分段区域至少有一个温度传感器2，温度传感器2置于大棚顶部下方的1/2-1/3甚至更低处，用于准确检测农作物周围的温度，8为分热源的结构装置，负责为此温度传感器所检测范围提供加热，保证此区域的温度在农作物适宜生长的范围之内，9为控制阀门，其受温度传感器2控制，当农作物周围的温度低于适宜生长温度时，主热源工作，此区域阀门打开，进行对此区域加热。The solution of the present invention is to measure the temperature in sections and control the heat source in sections, so as to realize the sectioned control of the greenhouse. Heat source, 7 is a ventilation device, responsible for ventilation for the greenhouse, 2 is a temperature sensor, the greenhouse is divided into multiple areas, and each area is arranged according to the density of crops. Temperature sensors 2, each segmented area There is at least one temperature sensor 2, and the temperature sensor 2 is placed at 1/2-1/3 or even lower under the top of the greenhouse to accurately detect the temperature around the crops. The detection range provides heating to ensure that the temperature in this area is within the suitable growth range of crops. 9 is a control valve, which is controlled by the temperature sensor 2. When the temperature around the crops is lower than the suitable growth temperature, the main heat source works. This area The valve opens to heat the area.
结构4为热源管路进口，其长度可覆盖大棚整个长度，其上有多个并联的分支结构，分别单独连接独立的分热源装置。结构5为热源管路出口，其长度可覆盖大棚的整个长度，其上也有多个并联的分支管路，用于联通热量的回收。Structure 4 is the inlet of the heat source pipeline, and its length can cover the entire length of the greenhouse. There are multiple parallel branch structures on it, which are respectively connected to independent sub-heat source devices. Structure 5 is the outlet of the heat source pipeline, and its length can cover the entire length of the greenhouse. There are also multiple parallel branch pipelines on it for the recovery of heat.
结构6为主热源，传统的方案为对热水进行加热，用热水作为主要传热媒介，特别要提到的是本方案不限于热水，当媒介为热水时，需要热水的进入和出口的管路装置，当期媒介为热空气时，不需要热源管路出口5，只需要加快结构7的排气，从而实现对大棚内部温度的调控。Structure 6 is the main heat source. The traditional solution is to heat hot water, using hot water as the main heat transfer medium. It should be mentioned that this solution is not limited to hot water. When the medium is hot water, hot water is required And the pipeline device of the outlet, when the current medium is hot air, the outlet 5 of the heat source pipeline is not needed, and only the exhaust of the structure 7 needs to be accelerated, so as to realize the regulation of the temperature inside the greenhouse.
图3为温控装置工作的控制方式，将大棚分割成多个独立的温控控制区域，当此区域的温度低于农作物的生长温度时，电脑根据预先设定好的程序，启动主热源6工作，同时打开此区域的分热源的开关，并启动分热源的风机进行工作，从而对此区域进行加温，当温度传感器检测到周围环境温度达到目标温度后，此时关闭主热源，关闭分热源的开关，同时停止风机工作，从而完成一个温度控制循环。Figure 3 shows the working control mode of the temperature control device. The greenhouse is divided into multiple independent temperature control control areas. When the temperature in this area is lower than the growth temperature of the crops, the computer will start the main heat source 6 according to the preset program. At the same time, turn on the switch of the sub-heat source in this area, and start the fan of the sub-heat source to heat the area. When the temperature sensor detects that the ambient temperature reaches the target temperature, turn off the main heat source and close the sub-heat source. The heat source is switched on and off, and the fan is stopped at the same time, thus completing a temperature control cycle.
图4为分热源的横截面图，分热源由部分大棚结构801，风机结构802以及分热源散热结构803组成，其中风机结构802为加快强制对流换热，热源管路为蛇形结构，为了美观，可在其上加上可透气的格栅结构，为了进一步理解分热源结构，图5为分热源的结构，管路为蛇形环形管路，其上有较多的金属翅片11。金属翅片11的存在提高了换热面积，可以有效提升换热效率，缩短主热源的工作时间，从而降低能耗消耗和维护成本。Figure 4 is a cross-sectional view of the sub-heat source. The sub-heat source is composed of a part of the greenhouse structure 801, a fan structure 802 and a sub-heat source heat dissipation structure 803. The fan structure 802 is for accelerating forced convection heat transfer, and the heat source pipeline is a serpentine structure for aesthetics. , a breathable grid structure can be added thereon. In order to further understand the sub-heat source structure, FIG. The existence of the metal fins 11 increases the heat exchange area, which can effectively improve the heat exchange efficiency and shorten the working time of the main heat source, thereby reducing energy consumption and maintenance costs.
本发明通过设置分段温度传感器2和独立并联的热源装置，将大棚分割成多个独立的区域，温度传感器可以根据农作物环境的温度，自动感应温度变化，然后与农作物的最适宜生长的温度对比，进而控制热源装置的开合，从而对此区域进行加热，实现分段精准控制，避免传统加热方式的缺陷，传统加热方式由于温度传感器和加热装置的限制，加热时对这个大棚进行加热，可能导致局部温度过高，导致农作物受损，除此之外，本发明通过分段精准控制，避免传统主热源长期工作，带来的成本和维护费用较高的问题，本发明可以控制主热源的开停，减少主热源的工作时间，从而减少能耗消耗和降低成本。总之，本方案可以有效提升传统大棚的温控效率，改善大棚对农作物的温控条件，从而提供更有利于农作物生长的条件。The present invention divides the greenhouse into multiple independent areas by setting segmental temperature sensors 2 and independent parallel heat source devices. The temperature sensor can automatically sense temperature changes according to the temperature of the crop environment, and then compare it with the optimum growth temperature of the crops. , and then control the opening and closing of the heat source device, so as to heat the area, realize segmental and precise control, and avoid the defects of the traditional heating method. Due to the limitation of the temperature sensor and the heating device, the traditional heating method heats the greenhouse during heating. The local temperature is too high and the crops are damaged. In addition, the present invention avoids the problem of high cost and maintenance costs caused by the long-term operation of the traditional main heat source through precise control in sections. The present invention can control the temperature of the main heat source. Start and stop, reduce the working time of the main heat source, thereby reducing energy consumption and cost. In short, this solution can effectively improve the temperature control efficiency of traditional greenhouses, improve the temperature control conditions of crops in greenhouses, and provide conditions that are more conducive to the growth of crops.
