[0028] CAN属于工业现场总线的范畴,是一种有效支持分布式控制和实时控制的串行通信网络,其优点为数据传输具有较好的实时性、可靠性和灵活性,接线简单,方便施工,同时总线上可挂控制单元的节点数量多,易于扩展。 [0028] CAN bus belonging to the category of the industrial field, is an effective and supports distributed real-time control of the serial communication network, the advantage of having better real-time data transmission, reliability and flexibility, wiring, easy number of construction, while the control unit can be linked to nodes on the bus, easy to expand. 本系统中可以设置通信速率2501A/S,在此速率下总线中的任意两节点间最大通信距离为270米,能够满足产业化生产的需要。 This system may be provided communication rate 2501A / S, in which the rate between any two nodes in the bus a maximum communication distance of 270 m, to meet the needs of industrial production.

[0029] 在总控制器11中保存了各反应器14中的藻类的相关信息,如藻类的名称、特性等,并结合当前实际的条件,如生产场地的温度和产品的需要等,确定每种藻类在反应器中生产时所需的至少一个环境参数。 [0029] stored in the overall controller 11 of each reactor is 14 information algae, algae such as the name, characteristics, and the current actual conditions, such as temperature and production space required products and the like, determine whether each the at least one environmental parameter required for algal species produced in the reactor. 由于在培养藻类时,藻类的实际生长环境与理想的生长环境即使存在比较小的误差也能够较好地培养藻类,因此,本发明实施例可以确定每个环境参数的理想值后,为每个环境参数设置一个包含理想值的范围值,该范围值的上限是可用的环境参数的最大值,下限是可用环境参数的最小值。 After culturing the algae due to algae growth actual environment and the ideal environment for the growth, even if the presence of a relatively small error can be better cultivation of algae, thus, the ideal value may be determined for each embodiment of the present invention the environmental parameters, for each environment parameter setting a range of values ​​comprising desired values, the upper limit of the range is the maximum value of the environmental parameters available, the lower limit is a minimum value available for the environmental parameters.

[0030] 当确定的环境参数对应的范围值发生变化时,可以通过管理员手动修正或计算机自动修正的方式确定更新后的环境参数,并将更新后的环境参数对应的范围值发送给子控制器13。 [0030] When the ambient parameter value changes corresponding to the determined range, the determined environment parameter updated manually by an administrator or the computer automatically correcting correction mode, transmission environment and the value of the updated parameters corresponding to a range of control of 13.

[0032] 针对总控制器11确定的环境参数不同,系统中的子控制器13的工作过程也不同, 下面针对不同的环境参数,分别说明子控制器13的工作过程。 [0032] The total environmental parameters for the controller 11 determines the different sub-systems during operation of the controller 13 is different, the following parameters for different environments, each operation will be described the sub-controller 13.

[0033] 实施例二: [0033] Example II:

[0034] 本发明实施例二是接收到的以环境参数中的一个环境参数是反应溶液温度为例, 来说明子控制器13对反应器14中藻类环境的监控。 Example [0034] Second, the present invention received in one environmental parameter of the environment parameter is the temperature of the reaction solution for example, the controller 13 for the seed 14 to monitor the algae reactor environment. 如图2所示,为一组控制子系统12中, 子控制器13、反应器14和各种传感器、执行器之间交互工作,完成温度监控的结构示意图, 假设涉及的子控制器13和反应器14是属于同一控制子系统12中的设备。 2, for a group control subsystem 12, the sub-controller 13, the interworking between the reactor 14 and the various sensors, actuators, monitoring the completion of the schematic structure of the temperature, according to the sub-controller 13 and assume 14 belonging to the same reactor control subsystem 12 of the device.

[0035] 下面对反应溶液温度控制过程进行说明: [0035] Next, the reaction solution temperature control process will be described:

[0036] 由于藻类都有一个最佳的生长温度,不同藻类的最佳生长温度可能存在差异,因此,总控制器11要根据不同的藻类确定各自对应的理想反应溶液温度和反应溶液温度对应的范围值,并将反应溶液温度对应的范围值发送给相应控制子系统中的子控制器13,同时还可以发送理想反应溶液温度。 [0036] Since the algae has an optimum growth temperature, optimum growth temperature different algae may differ, and therefore, the overall controller 11 to be determined over the respective corresponding reactions depending on the algae solution and the reaction solution temperature corresponding to the temperature range of values, and the range of the reaction solution temperature to a value corresponding to the respective sub-controller of the control subsystem 13, but also can be transmitted over the temperature of the reaction solution.

[0037] 子控制器13在接收到的至少一个环境参数中,发现存在一个环境参数是反应溶液温度,则子控制器13将通过温度传感器(如温度计)对反应器内的反应溶液温度进行检测,并将检测的反应溶液温度与总控制器11发送的反应溶液温度对应的范围值进行比较, 得到以下两种情况: [0037] In at least one sub-controller 13 receives environmental parameter, the environmental parameter is found a solution, the reaction temperature, the sub-controller 13 detects the temperature of the reaction solution in the reactor by the temperature sensor (e.g., a thermometer) , the temperature of the reaction solution and the reaction solution temperature detected transmitted and the overall controller 11 compares the range of values ​​corresponding to, the following two cases:

[0038] 如果反应器内检测得到的反应溶液温度在接收到的反应溶液温度对应的范围值内,即反应器14中反应溶液温度适合藻类生长,则不必调整反应器14中反应溶液的温度; 否则 [0038] If the reaction solution temperature within the reactor detection obtained in the range of the solution temperature of the reaction corresponding to the received, i.e., the reactor 14 the reaction solution temperature suitable for the growth of algae, it is necessary to adjust the temperature of the reactor in the reaction 14 solution; otherwise

[0039] 表示反应器14中反应溶液温度过高或过低,不适合藻类生长,则调整反应器14内的反应溶液的温度,使反应器14的反应溶液温度在总控制器11发送的反应溶液温度对应的范围值内,较优地,使反应器14的反应溶液温度尽可能地接近理想反应溶液温度。 [0039] The reactor 14 represents the reaction solution temperature is too high or low, is not suitable for the growth of algae, the reactor temperature is adjusted in the reaction solution 14, the reactor temperature of the reaction solution was reacted at 14 sent by the overall controller 11 within the range of values ​​corresponding to the temperature of the solution, and more, the temperature of the reaction solution of the reactor 14 as close as possible over the temperature of the reaction solution.

[0040] 具体地,本实施例二采用温室湿帘风扇设备降低空间温度,进而降低反应器内反应溶液温度,以及通过向温室内板式换热器通热水来升高空间温度,进而升高反应器内反应溶液温度。 [0040] In particular, according to a second embodiment of the present wet curtain fan apparatus in greenhouse space temperature decreased, thereby reducing the temperature of the reaction solution within the reactor, and by-pass to be raised in a greenhouse space temperature hot plate heat exchanger, and thus raised the reaction solution temperature within the reactor. 具体调整过程如下: Specific adjustment process is as follows:

[0041] 子控制器13通过PT100温度传感器测量反应器14中反应溶液温度,如果得到的反应器14内的反应溶液温度大于总控制器11发送的反应溶液温度对应范围值的上限值, 则子控制器13启动温室湿帘风扇设备进行降温。 [0041] The sub-controller 13 is measured by a temperature sensor PT100 reactor 14 the reaction solution temperature, if the temperature of the resulting reaction solution within the reactor 14 is greater than the upper limit value of the reaction solution temperature range corresponding to the total value sent by the controller 11, the the sub-controller 13 starts greenhouse wet curtain fan to cool the device.

[0042] 温室湿帘风扇设备是利用水蒸发降温实现降温目的的,当冷水均勻地淋湿湿帘墙时,通过一组风扇向湿帘墙吹风,由带出的湿冷空气降低空间内的温度,进而降低反应器内反应溶液温度,使得反应器14的反应溶液温度降低至总控制器11发送的反应溶液温度对应的范围值内。 [0042] Greenhouse wet curtain fan apparatus is the use of evaporative cooling to achieve the purpose of cooling the water when the cold water is uniformly wet wet curtain wall, by a set of fan curtain wall to the wet hair, reduce the temperature in the space from the wet out of the cold and further reducing the solution temperature of the reactor within the reactor, the temperature of the reaction solution of the reactor 14 is reduced to a temperature within the range of values ​​of the total reaction solution was sent by the controller 11 corresponds.

[0043] 如果得到的反应器14内的反应溶液温度小于总控制器11发送的反应溶液温度对应范围值得下限值,则子控制器13通过向温室内板式换热器通热水,以提高反应器14内的反应溶液温度,使反应器14的反应溶液温度升高至总控制器11发送的反应溶液温度对应的范围值内。 [0043] If the temperature of the reaction solution within the reactor 14 to obtain the reaction solution temperature is less than the total range corresponding to the transmission controller 11 worth lower limit, the sub-controller 13 of the hot water into the greenhouse through the plate heat exchanger, in order to improve temperature of the reaction solution within the reactor 14, the reactor 14 the temperature of the reaction solution was elevated to a temperature in the range of the total value of the reaction solution was sent by the controller 11 corresponds.

[0044] 板式换热器是由一系列具有一定波纹形状的金属片叠装而成的一种新型高效换热器。 [0044] The plate heat exchanger consists of a series of corrugated metal sheet having a certain shape, stacked together in a new and efficient heat exchanger. 各种板片之间形成薄矩形通道,当热水流过时与外界空气进行热量交换,以达到升温的目的。 It is formed between the thin plates of various rectangular channel, the hot water flow out of date when the outside air for heat exchange, for the purpose of warming.

[0045] 本实施例二中涉及的冷水是指温度小于总控制器11发送的反应溶液温度对应范围值的上限值的液体,热水是指温度大于总控制器11发送的反应溶液温度对应范围值的下限值的液体。 [0045] The present embodiment relates to a cold water Second embodiment refers to a temperature less than the upper limit value of the liquid reaction solution temperature range corresponding to the total value sent by the controller 11, the hot water refers to a temperature greater than the reaction temperature of the total solution, corresponding to the transmission controller 11 liquid lower limit of the range of values.

[0046] 在本实施例二中,为了使温度控制更加准确、响应速度更快,可以采用双闭环串极控制实现对温度的调控。 [0046] Example II In the present embodiment, in order to make temperature control more accurate, faster response, can be employed to achieve dual loop serial control electrode of the regulation temperature. 如图2所示,子控制器13利用温室湿帘风扇设备或板式换热器调节反应器14内的反应溶液温度时,继续通过温度传感器对反应器14中的反应溶液温度进行测量,根据反馈结果调整升温或降温的程度。 As shown, the sub-controller 13 when using the fan apparatus or greenhouse wet curtain plate heat exchanger the temperature of the reaction solution was adjusted in the reactor 14, proceeds through the temperature sensor 2 of the temperature of the reaction solution in the reactor 14 measures, based on feedback the results adjust the degree of heating or cooling. 例如,可以设定第一门限值,该第一门限值大于反应溶液温度对应范围值的上限值。 For example, setting the first threshold value, the first threshold value is greater than the upper limit temperature of the reaction solution corresponding to a range of values. 当反应器14的反应溶液温度高于总控制器11发送的反应溶液温度对应范围值的上限值,且差值大于第一门限值时,表示反应器14的反应溶液温度与适合藻类生长的温度差别较大,需要快速调整,则增大温室湿帘风扇设备的工作效率,进行快速降温;当反应器14的反应溶液温度高于总控制器11发送的反应溶液温度对应范围值的上限值,且差值小于第一门限值时,表示反应器14的反应溶液温度已经接近合适的温度,需要进行精确调整,避免反应器内的温度急剧降得过低,则减小温室湿帘风扇设备的工作效率,进行精确降温,保证温度控制的准确性。 When the reaction solution temperature of the reactor 14 is higher than the upper limit of the reaction solution temperature range corresponding to the total value sent by the controller 11, and the difference is greater than a first threshold value, it indicates the temperature of the reaction solution of the reactor 14 with a suitable algal growth large temperature differences need to quickly adjust, work efficiency is increased greenhouse wet curtain fan device for rapid cooling; the temperature of the reactor when the reaction solution 14 is higher than the temperature of the reaction solution is sent by the controller 11 corresponding to the total range of values limit value, and the difference is less than the first threshold value, indicates the temperature of the reaction solution is close to the reactor 14 has a suitable temperature, requires precise adjustment, to avoid a sharp temperature drop in the reactor is too low, the greenhouse is reduced wet curtain fan efficiency device for precise cooling, to ensure the accuracy of temperature control.

[0047] 升温的过程与上述降温的过程类似。 [0047] The above-described heating process and cooling process are similar.

[0048] 在本发明实施例二的系统中,主控制器11向各控制子系统12中的子控制器13发送了反应溶液温度对应的范围值,则每个子控制器13对反应器14的反应溶液温度进行调整,使反应器14内的反应溶液温度保持在对应的范围值内,保证培养的藻类有合适的生长环境。 [0048] In the present invention, the system according to the second embodiment, the main controller 11 controls the respective sub-controller subsystem 1213 transmits the range value corresponding to the temperature of the reaction solution, then the controller 13 for each sub-reactor 14 the reaction temperature was adjusted so that the temperature of the reaction solution within the reactor 14 is maintained within a corresponding range of values ​​to ensure proper culture of algae growth environment. 同时,采用闭环串极控制,使温度调整的响应速度更快,温度控制更准确。 At the same time, closed loop control electrode string, the temperature adjustment response speed faster, more accurate temperature control.

[0049] 实施例三: [0049] Example III:

[0050] 本发明实施例三是以接收到的环境参数中的一个环境参数是反应溶液酸碱度和反应溶液溶氧度为例,来说明子控制器13对反应器14中藻类环境的监控。 Example [0050] Third, the present invention is one environmental parameter of the environment parameter is received by the reaction solution of pH and dissolved oxygen of the reaction solution, for example, the controller 13 is Akiko reactor 14 monitoring environment algae. 如图3所示,为一组控制子系统12中,子控制器13、反应器14和各种传感器、执行器之间交互工作,完成酸碱度和溶氧度监控的结构示意图,假设涉及的子控制器13和反应器14是属于同一控制子系统12中的设备。 As shown, for a group control subsystem 12, the sub controller 13, various sensors and the reactor 14, the interworking between the actuator, pH and dissolved oxygen to complete the monitoring of a schematic structure of assumptions regarding sub 3 the controller 13 and 14 belonging to the same reactor control subsystem 12 of the device.

[0051] 培养液的pH值(即酸碱度)和溶解氧浓度(溶氧度)是影响藻类生长的重要因素之一,通过向反应器14中通入酸碱性物质调节pH值,使反应器14中的反应溶液的酸碱度符合藻类培养的需求。 [0051] The pH (i.e., pH) and dissolved oxygen concentration of the culture medium (dissolved oxygen level) is one of the important factors that affect the growth of algae, the pH is adjusted by the acid material passed through the reactor 14, the reactor pH of the reaction solution 14 in line with the needs of the algae culture. 另外,由于光合作用不断产生氧气,反应溶液的中的氧气很容易达到过饱和状态,而氧气浓度过高会抑制藻类生长,通过向反应器14通入气体可以使空气与反应溶液的界面接触不断更新,使多于饱和浓度的溶氧逸入空气中,降低溶解氧浓度。 Further, since the continuous photosynthesis produces oxygen, oxygen in the reaction solution is easily reached saturation, while the oxygen concentration is too high will inhibit the growth of algae, can interfacial contact with the air through the reaction solution continuously into the reactor 14 through the gas update the saturation concentration of dissolved oxygen than escape into the air, reducing the dissolved oxygen concentration.

[0052] 总控制器11首先根据藻类生长所需的理想环境确定反应溶液酸碱度和反应溶液溶氧度的理想值和对应的范围值,并将反应溶液酸碱度和反应溶液溶氧度对应的范围值发送给相应的子控制器13,较优地,还可以发送理想值。 [0052] The controller 11 first determines the total value and a corresponding reaction over the range pH value of the solution and the solution of dissolved oxygen in the reaction according to ideal environment needed for growth of algae, and the reaction pH range of the solution of dissolved oxygen and the reaction solution corresponding to transmitted to the respective sub-controller 13, and more, the ideal value may also be transmitted.

[0053] 子控制器13通过酸碱度检测传感器(如pH电极)对反应器14中的反应溶液的酸碱度进行测量,并将测量结果与总控制器11发送的反应溶液酸碱度对应的范围值进行比较,根据比较结果有以下两种可能的情况: [0053] The sub-controller 13 pH 14 reaction solution in the reactor was measured by a pH detecting sensor (e.g., pH electrode), and the pH of the reaction solution was measured result corresponding to the total range of values ​​sent by the controller 11 compares, there are two possible scenarios based on the comparison:

[0054] 如果检测后得到的反应器14内的反应溶液酸碱度在总控制器11发送的反应溶液酸碱度对应的范围值内,则反应器14内的反应溶液符合藻类培养的条件,不需要调整酸碱度; The reaction solution in the [0054] pH of the reaction solution within 14 detects if the reactor is obtained in the range pH value of the reaction solution was sent by the controller 11 corresponding to the total, the reactor 14 matches the algal culture, not necessary to adjust pH ;

[0055] 否则,需要向反应器14内通入酸性或碱性物质,以调整反应器内的反应溶液的酸碱度,使反应器14的反应溶液酸碱度在总控制器11发送的反应溶液酸碱度对应的范围值内。 [0055] Otherwise, it is necessary acidic or alkaline substances into the reactor 14, to adjust the pH of the reaction solution in the reactor, the reactor 14 corresponds to the reaction solution pH of the reaction solution pH in the overall controller 11 transmits within a range of values.

[0056] 另外,子控制器13还通过溶氧检测传感器(如溶氧电极)对反应器14中的反应溶液的溶氧度进行测量,并将测量结果与总控制器11发送的反应溶液溶氧度对应的范围值进行比较,根据比较结果有以下两种可能的情况: [0056] Further, the sub-controller 13 further measures the dissolved oxygen of the reaction solution in the reactor 14 through the oxygen detection sensor (e.g., oxygen electrode), and the measurement results of the total reaction solution was dissolved the transmission controller 11 range of values ​​corresponding to the degree of oxygen compared, there are two possible cases according to the comparison result:

[0057] 如果检测后得到的反应器14内的反应溶液溶氧度在总控制器11发送的反应溶液溶氧度对应的范围值内,则反应器14内的反应溶液符合藻类培养的条件,不需要通入气体调整溶氧度; [0057] The reaction solution of the dissolved oxygen in the reactor 14 if the detected values ​​obtained in the range of dissolved oxygen of the reaction solution was sent by the controller 11 corresponding to the total, the reaction solution within the reactor 14 matches the algal culture, It does not need to adjust the dissolved oxygen of the gas fed;

[0058] 如果检测后得到的反应器14内的反应溶液溶氧度大于总控制器11发送的反应溶液溶氧度对应范围值的上限值,则需要向反应器14内通入气体,以降低反应器内的反应溶液的溶氧度。 Upper limit value [0058] If the detected reactor obtained reaction solution of dissolved oxygen in the reaction solution 14 is greater than a corresponding range of values ​​of the total oxygen transmitted by the controller 11 is required to the reactor 14 through the gas to reducing the dissolved oxygen of the reaction solution in the reactor. 通入的气体可以为空气或空气与二氧化碳的混合气体。 Feed gas may be air or a mixed gas of air and carbon dioxide.

[0059] 在本实施例中,将反应溶液酸碱度和反应溶液溶氧度同时作为环境参数对反应器中反应溶液的环境进行调整,本实施例也不限于仅将反应溶液酸碱度或仅将反应溶液溶氧度作为环境参数对反应器中反应溶液的环境进行调整。 [0059] In the present embodiment, the reaction solution pH and dissolved oxygen of the reaction solution at the same time as the environment parameter of the environment to adjust the reaction solution in the reactor, the present embodiment is not limited to only the pH of the reaction solution or the reaction solution only dissolved oxygen of the environment parameter of the environment to adjust the reaction solution in the reactor.

[0060] 在调整反应器14内的反应溶液酸碱度时,对反应溶液的PH值过大或过小的具体处理方式为: [0060] When the reaction solution to adjust the pH in the reactor 14, the reaction solution PH value is too large or too small for the particular treatment:

[0061] 如果检测后得到的反应器14内的反应溶液酸碱度大于总控制器11发送的反应溶液酸碱度对应范围值的上限值,则子控制器13向反应器14内通入空气和二氧化碳的混合气体时,增加通入的二氧化碳浓度,使混合气体的酸性增强,降低反应器14的反应溶液的PH值,直到在总控制器11发送的反应溶液酸碱度对应的范围值内。 [0061] If the detection obtained reaction solution pH of reactor 14 is greater than the upper limit value in the pH range corresponding to the total value of the reaction solution was sent by the controller 11, the sub controller 13 through the air and carbon dioxide to the reactor 14 when the mixed gas to increase the concentration of carbon dioxide into the mixed gas acidity, reducing the PH value of reaction 14 solution until the reaction solution in the range pH value of the overall controller 11 corresponding to the transmission. 本发明实施例也不限于通入其他酸性物质。 Embodiments of the present invention is not limited into other acidic substances.

[0062] 由于通入空气和二氧化碳的混合气体的同时能够降低反应器14内的反应溶液溶氧度,因此,对反应溶液酸碱度的检测可以与反应溶液溶氧度的检测同时进行。 [0062] Because simultaneously a gas mixture of air and carbon dioxide, while the reactor can be reduced dissolved oxygen level within the reaction solution 14, and therefore, the detection of the pH of the reaction solution can be detected with the reaction solution dissolved oxygen degrees. 具体地,可以根据图3所示的闭环反馈结构同时调整反应器14的pH值和溶氧度,做法如下: Specifically, while the reactor was adjusted closed-loop feedback structure shown in FIG. 3 pH and dissolved oxygen value of 14, the following approach:

[0063] 如果通入的反应器14是空气和二氧化碳的混合气体,则子控制器13通过pH电极对通入混合气体后反应器14内反应溶液酸碱度进行测量,实时与总控制器11发送的反应溶液酸碱度对应的范围值进行比较,当比较结果为大于对应的范围值的上限值,且差值大于第二门限值时,表示反应器14内反应溶液酸碱度与合适的酸碱度差别较大,需要快速调整,则通过流量计反馈的流量信息,开大空气比例阀和二氧化碳比例阀(这里也可以只开大二氧化碳比例阀),使更多的酸性气体进入混合气体罐后,由曝气比例阀通入反应器14。 [0063] If the reactor 14 through the mixed gas of air and carbon dioxide, the sub-controller 13 by a pH electrode pH of the reaction solution inside of the reactor 14 after the gas mixture is measured, transmitted in real time to the total controller 11 the reaction solution was pH range corresponding to the value, when the comparison result is greater than the corresponding upper limit value of a range of values, and the difference is greater than a second threshold value, the reactor 14 represents the pH of the reaction solution with a suitable pH large difference , need to quickly adjust the flow rate information is fed back through the flow meter, a large open air and carbon dioxide proportional valve proportional valve (here, the carbon dioxide may be only large open proportional valve), so that more acid gas mixture into the gas tank, the aeration proportional valve 14 into the reactor. 当比较结果为大于对应的范围值的上限值,且差值小于第二门限值时,表示反应器14内反应溶液酸碱度与合适的酸碱度差别较小,需要精确调整,则关小空气比例阀和二氧化碳比例阀(这里也可以只关小二氧化碳比例阀),使单位时间内通入反应器14的酸性气体较少, 保证反应器14的反应溶液酸碱度尽可能接近理想反应溶液酸碱度。 When the comparison result is greater than the corresponding upper limit value of a range of values, and the difference is less than the second threshold value, the reactor 14 represents the pH of the reaction solution with a suitable pH difference is small, an accurate adjustment of the air ratio small clearance and carbon dioxide valve proportional valve (here, the carbon dioxide may be only a small proportional valve closed), the acid gas was passed through the reactor 14 per unit time is small, to ensure that the pH of the reaction solution of the reactor 14 as close to the reaction solution over the pH.

[0064] 图3所示的闭环反馈结构还可以调节反应溶液溶氧度,由反应器13通过溶氧电极测量调整后的反应器14的反应溶液溶氧度,如果得到的溶氧度大于总控制器11发送的反应溶液溶氧度对应范围值的上限值,则开大空气比例阀和二氧化碳比例阀,同时,考虑到通入混合气体对酸碱度的影响,可以在二氧化碳比例阀不调整的情况下,仅开大空气比例阀, 则不会对反应器14的反应溶液酸碱度造成影响。 [0064] The closed-loop feedback structure shown in FIG. 3 may also be adjusted dissolved oxygen of the reaction solution, the reaction solution by the dissolved oxygen of 13 by adjusting the dissolved oxygen measuring electrode reactor reactor 14, if the resulting total dissolved oxygen is greater than the reaction solution was the upper limit of dissolved oxygen corresponding to the value of the transmission range of the controller 11, the proportional valve to open large air proportional valve, and carbon dioxide, while taking into account the influence of the gas mixture of pH, carbon dioxide may not be adjusted in the proportional valve case, only the large open air proportional valve, the reaction will not pH 14. the reaction solution was affected. 如果得到的溶氧度大于总控制器11发送的反应溶液溶氧度对应范围值的上限值,且差值小于第三门限值,则关小空气比例阀和二氧化碳比例阀,同时,考虑到通入混合气体对酸碱度的影响,可以在二氧化碳比例阀不调整的情况下,仅关小空气比例阀,则不会对反应器14的反应溶液酸碱度造成影响。 If the upper limit of dissolved oxygen obtained reaction solution was greater than the overall controller of dissolved oxygen corresponding to the range value of the transmission 11, and the difference is less than the third threshold value, the valve off a small proportion of air and carbon dioxide proportional valve, at the same time, consider the Effect of the mixed gas fed to the pH, carbon dioxide may be a case where the proportional valve is not adjusted, and only a small proportion of air valve off, the reaction solution pH will not reactor 14 is affected.

[0065] 如果检测后得到的反应器14内的反应溶液酸碱度小于总控制器11发送的反应溶液酸碱度对应范围值的上限值,则子控制器13向反应器14内通入空气和二氧化碳的混合气体时,降低通入的二氧化碳浓度,使混合气体的酸性减弱,增大反应器14的反应溶液的PH值,直到在总控制器11发送的反应溶液酸碱度对应的范围值内。 [0065] The pH of the reaction solution within the reactor 14 is obtained if the detection is less than the upper limit of the pH range corresponding to the total value of the reaction solution was sent by the controller 11, the sub controller 13 through the air and carbon dioxide to the reactor 14 when mixed gas, reducing the concentration of carbon dioxide into the mixed gas of reduced acidity, increasing the PH value of the reactor 14 the reaction solution until the reaction solution in the range pH value of the overall controller 11 corresponding to the transmission.

[0066] 此时,为了在调整反应溶液溶氧度时避免对酸碱度的影响,子控制器13可以仅开大或关小空气比例阀,不调整二氧化碳比例阀。 [0066] In this case, in order to avoid the influence of pH of the reaction solution in the adjustment of the dissolved oxygen, the sub-controller 13 can start only the proportion of air or closed by a valve, carbon dioxide is not adjusted proportional valve. [0067] 本实施例三通过控制空气和二氧化碳电/气比例阀调节曝气,实现对每个子系统12中的pH值和溶解氧浓度的控制,同时,通过闭环控制系统对通入混合气体的调整,使调整后的反应器14的反应溶液酸碱度、反应溶液溶氧度调整速度快,且调整精确,较好地处于合适的状态。 [0067] Example Three of the present embodiment by controlling the air and carbon dioxide, electric / gas proportional valve regulating the aeration, each subsystem to achieve control of the pH and dissolved oxygen concentration of 12, while closed-loop control system of a gas mixture adjusted so that the reactor was adjusted to pH 14 reaction solution, the reaction solution to adjust the speed of dissolved oxygen, precisely adjusted and, preferably is in the appropriate state.

[0068] 考虑到藻类在生长过程中需要利用反应溶液中的二氧化碳进行光合作用,本发明实施例三中通入的二氧化碳除了对反应溶液的酸碱度进行调节,还可以作为藻类光合作用的原料。 [0068] Taking into account the growth of algae in the process requires the reaction solution with carbon dioxide for photosynthesis, into three in the embodiment of the present invention, in addition to the embodiment of the carbon dioxide the reaction solution was adjusted pH, it may also be used as raw material for photosynthesis of algae. 如果通过向反应溶液通入二氧化碳和氧气的混合气体使得反应溶液的酸碱度适宜藻类的生长,则此时通入的二氧化碳气体足以供给藻类的光合作用。 If the gas mixture through a carbon dioxide and oxygen so that the growth of algae in a suitable pH of the reaction solution to the reaction solution, this time into the carbon dioxide gas supply sufficient photosynthesis algae. 当藻类生长过程中消耗掉反应溶液中大量的二氧化碳时,反应溶液的酸碱度很可能会高于总控制器11发送的反应溶液酸碱度对应范围值的上限值,则根据本发明实施例三的方案将大量地向反应器中通入二氧化碳,在保证酸碱度适宜的情况下也保证了藻类的光合作用对二氧化碳的需求。 When algae growth process a large amount of carbon dioxide consumed in the reaction solution, the pH of the reaction solution is likely to be higher than the upper limit of the pH range corresponding to the total value of the reaction solution was sent by the controller 11, in accordance with the present invention according to a third embodiment the large amount of carbon dioxide into the reactor, in a case where a suitable pH to ensure the photosynthesis of algae also ensures that the demand for carbon dioxide.

[0069] 实施例四: [0069] Example IV:

[0070] 本发明实施例四是以接收到的环境参数中的一个环境参数是反应溶液液位和反应溶液内藻类浓度为例,来说明子控制器13对反应器14中藻类环境的监控。 Example [0070] The present invention is based on a four parameter ambient environment parameter is received in a reaction solution level and concentration of algae within the reaction solution, for example, the controller 13 is Akiko reactor 14 monitoring environment algae.

[0071] 本实施例四中的任一组控制子系统12中,子控制器13、反应器14和各种传感器、 执行器之间交互工作,完成反应溶液液位和反应溶液内藻类浓度监控的结构示意图,假设涉及的子控制器13和反应器14是属于同一控制子系统12中的设备。 [0071] In the present embodiment according to any one of a set of four control subsystem 12, the sub-controller 13, the interworking between the reactor 14 and the various sensors, actuators, to the reaction solution to complete the algae concentration level and the reaction was monitored structure diagram, according to the sub-controller 13 is assumed and 14 belonging to the same reactor control subsystem 12 of the device.

[0072] 总控制器11首先根据藻类生长所需的理想环境确定反应溶液液位和反应溶液内藻类浓度的理想值和对应的范围值,并将反应反应溶液液位和反应溶液内藻类浓度对应的范围值发送给相应的子控制器13,较优地,还可以发送理想值。 [0072] The master controller 11 over the first algae growth environment determination required for the reaction solution over the value of the level and concentration of algae in the reaction solution and the corresponding range of values ​​according to the reaction and the concentration of algae in the reaction solution, and the reaction solution corresponding to the liquid level the range of values ​​corresponding to a sub-controller 13, and more, the ideal value may also be transmitted.

[0073] 子控制器在确定接收到的环境参数中的一个是反应溶液液位和反应溶液内藻类浓度后,通过浓度检测传感器对反应器中反应溶液内藻类浓度进行检测,并将检测结果与接收到的反应溶液液位对应的范围值进行比较,得到以下两种比较结果: [0073] In a sub-controller determines that the received ambient parameter is the concentration of algae after the reaction solution and the reaction solution level, detects a concentration of algae in the reaction solution within the reactor by the concentration detecting sensor, and the detection result the reaction solution was level range corresponding to the received value, to obtain two comparison results:

[0074] 如果检测后得到的反应器的反应溶液内藻类浓度在总控制器发送的藻类浓度对应范围值内时,表示反应器内藻类还需继续培养,不能进行收集。 [0074] The concentration of algae in the reaction solution in the reactor is obtained if the detection of the total concentration of algae is within a corresponding range value sent by the controller, indicates the need to continue the culture of algae in the reactor can not be collected.

[0075] 如果检测后得到的反应器的反应溶液内藻类浓度高于总控制器发送的藻类浓度对应范围值的下限值,表示反应器内藻类需要收集,则排除反应器内的包含藻类的反应溶液。 [0075] If the concentration of algae in the reaction solution in the reactor is higher than that obtained after the detection lower limit value of the range corresponds to the concentration of algae overall controller transmits, showing the reactor needs to be collected algae, the algae contained in the excluded reactor The reaction solution. 在排除藻液后,由于液位降低,并且降低至反应溶液液位对应范围值的下限值时,需要向反应器中添加反应溶液,使反应器的反应溶液内藻类浓度低于总控制器发送的藻类浓度对应范围值的下限值,且反应器的反应溶液液位在总控制器发送的反应溶液液位对应的范围值内。 After the reaction solution when alginate was negative, due to the reduced level, and the level was reduced to a lower limit value corresponding to a range of values ​​of the reaction, the reaction solution needs to be added to the reactor, the reactor is lower than the total concentration of algae controller the reaction solution was within the level corresponding to the lower limit of the range of values ​​of the concentration of algae is transmitted, and the reaction solution in the reactor level controller sends the total range of values ​​corresponding to.

[0076] 在实施例四的闭环反馈系统中,需要根据调整的各个阶段选择合适的排除流量和添加流量。 [0076] In an embodiment, four closed loop feedback system, it is necessary to select the appropriate negative and add traffic flow in accordance with various stages of adjustment. 具体做法如下: Specifically, the following:

[0077] 子控制器排除部分藻液后,利用浓度检测传感器对反应器中反应溶液内藻类浓度进行实时检测,由于排除藻液并添加了反应溶液,则反应器中反应溶液内藻类浓度已经在一定程度上降低,低于总控制器发送的藻类浓度对应范围值的下限值时,表示不需要再收集藻类,而应该继续培养。 After the [0077] sub-controller exclude some algae solution, using the density detection sensor in the concentration of algae in the reactor the reaction was detected in real time, due to the elimination of the algae solution and the reaction solution was added, the algae concentration in the reaction solution in the reactor has been when a certain degree of reduction, below the lower limit concentration of algae corresponding to the total range of values ​​sent by the controller, do not need to represent the collection of algae, but the culture should continue.

[0078] 实施例五: [0078] Example Five:

[0079] 本发明实施例五是以接收到的环境参数中的一个环境参数是光照度为例,来说明子控制器13对反应器14中藻类环境的监控。 Example [0079] Fifth, the present invention is one environmental parameter of the environment parameter is the received light level as an example, the controller 13 is Akiko reaction vessel 14 to monitor the environment of algae.

[0080] 总控制器11首先根据藻类生长所需的理想环境确定光照度的理想值和对应的范围值,并将光照度对应的范围值发送给相应的子控制器13,较优地,还可以发送理想值。 [0080] The controller 11 first determines the total value over the range of values ​​corresponding to light intensity required for growth of algae according to an ideal environment, and transmitted to the respective sub-controllers 13, more of the light corresponding to a range of values, can also send the ideal value.

[0081] 子控制器在确定需要对光照度进行调控时,可以通过照度计(数字式光照度传感器)对反应器周围的光照进行检测,并将检测结果与接收到的光照度对应的范围值进行比较,有以下两种比较结果: [0081] The sub-controller when determining the need for illumination regulate, can be detected illumination around the reactor by a luminometer (digital light level sensor), the detection result is compared with the light intensity corresponding to the received range of values, there are two comparison results:

[0082] 如果检测后得到的反应器周围的光照度在总控制器发送的光照度对应的范围值内,表示当前反应器周围的光照度满足藻类生长需求,不需要进行光照度调整。 [0082] If the detected light intensity obtained around the reactor in the range of light intensity values ​​corresponding to the total transmission controller, indicates that the current illuminance around the reactor to meet the growth requirements of algae, the light adjustment is not required.

[0083] 如果检测后得到的反应器周围的光照度不在总控制器发送的光照度对应的范围值内,则需要调整反应器周围的光照度,使反应器的光照度在总控制器发送的光照度对应的范围值内。 The [0083] range values ​​illumination if detection obtained illuminance around the reactor is not always sent by the controller corresponding to the need to adjust the light level around the reactor, the reactor illuminance in the illumination within the overall controller transmits the corresponding value within.

[0084] 具体地,在需要调整反应器周围的光照度时,调整的方式如下: [0084] Specifically, when the need to adjust the light level around the reactor, adjusted as follows:

[0085] 子控制器通过照度计检测后确定:反应器周围的光照度大于总控制器发送的光照度对应范围值的上限值时,则可以通过利用遮挡物遮挡反应器周围的光照,使反应器的光照度在总控制器发送的光照度对应的范围值内。 [0085] After detected by the sub-controller determines illuminometer: when illuminance around the reactor is greater than the upper limit value of the light intensity corresponding to the total range of values ​​sent by the controller, may be light shielding around the reactor by using a shield, the reactor illuminance in the light of the overall controller transmits the corresponding range of values. 在反应器周围的光照度小于总控制器发送的光照度对应范围值的下限值时,可以去除用于遮挡反应器周围光照的遮挡物。 When the light level around the reactor is less than the lower limit of the overall controller transmitted light illumination corresponding to a range of values, the covering can be removed for blocking illumination around the reactor.

[0086] 本实施例中涉及的遮挡物可以是电动遮光帘,在需要遮光时,把遮光帘拉到指定位置,到位时机械限位开关状态改变,控制电机停转。 [0086] according to the present embodiment may be an electric shield shade, when the light-shielding required, the shade pulled specified position, when the mechanical limit switch state change place, the control motor is stopped. 当需要采光时,控制电机再把遮光帘拉回原位。 When you need lighting, motor control blinds then back to its original position.

[0087] 在某些情况下光照度太弱,可以通过定波长LED光源对反应器补光。 [0087] In some instances the light intensity is too weak, it can be given wavelength LED light source to fill the reactor.

[0088] 本发明实施例二至实施例五是分别以一种环境参数为例来说明藻类反应控制过程,本发明实施例也不限于将实施例二至实施例五涉及的环境参数结合在一起,由子控制器并行根据多个环境参数对藻类反应控制过程进行处理。 Example [0088] Example embodiments of the present invention is two to five, respectively, in an environmental parameter is an example to illustrate the reaction of algae control process, embodiments of the present invention is not limited to two environmental parameter according to a fifth embodiment relates to an embodiment in conjunction with the , parallel processing by the sub-controller of the control procedure according to the reaction algae plurality of environmental parameters.
