Description
技术领域technical field
本发明属于粮仓设备测试领域,具体涉及一种粮仓设备耐熏蒸测试装置和方法。The invention belongs to the field of granary equipment testing, and in particular relates to a granary equipment fumigation resistance test device and method.
背景技术Background technique
在粮食储藏过程中,受多种因素影响,经常会发生储粮虫害现象,每年因粮食霉变及虫害等造成的损失占很大比重,如果不有效控制和杀灭这些储量害虫,不仅会引起储粮的大量损失,还会严重影响储粮的品质,危害非常大。因此,在粮食储藏过程中,必须进行有效的控制并杀灭储粮害虫。In the process of grain storage, due to the influence of various factors, the phenomenon of stored grain insect pests often occurs, and the annual losses due to grain mildew and insect pests account for a large proportion. If these stored pests are not effectively controlled and killed, it will not only cause A large loss of stored grain will also seriously affect the quality of stored grain, which is very harmful. Therefore, in the process of grain storage, it is necessary to effectively control and kill stored grain pests.
现在防治储粮虫害的主要手段是采用化学熏蒸法进行熏蒸杀虫,化学熏蒸法是采用化学熏蒸剂在密闭的储粮仓库中杀死储粮害虫、病菌等的一种技术,可以迅速地大规模地歼灭害虫。目前国际上在储粮领域主要采用的化学熏蒸剂是磷化氢,磷化氢是一种无色、剧毒、易燃的气体,它扩散性好、挥发性好、易于向粮堆下层渗透,是一种性能良好的熏蒸剂,广泛应用于在我国粮食仓储企业的日常杀虫作业中。磷化氢一般是通过采用磷化铝片、磷化锌、磷化钙等和空气中的水分子发生反应来产生获取,最常用的是磷化铝。At present, the main means of preventing and controlling insect pests in stored grains is to use chemical fumigation to fumigate and kill insects. Chemical fumigation is a technology that uses chemical fumigants to kill stored grain pests and germs in closed grain storage warehouses. Exterminate pests on a large scale. At present, the main chemical fumigant used in the field of grain storage in the world is phosphine. Phosphine is a colorless, highly toxic and flammable gas. It has good diffusivity, good volatility, and is easy to penetrate into the lower layer of grain pile , is a fumigant with good performance, and is widely used in the daily insecticide operations of grain storage enterprises in my country. Phosphine is generally produced by using aluminum phosphide, zinc phosphide, calcium phosphide, etc. to react with water molecules in the air, and the most commonly used one is aluminum phosphide.
磷化氢具有一定的腐蚀性,容易与铜或铜合金等金属产生反应导致金属被腐蚀。金属铜作为电子设备和装置的主要材料之一,其应用非常广泛,因此磷化氢对于电子设备的腐蚀性较强。随着粮食仓储智能化和信息化的不断发展,粮仓设备也不断增多,粮仓设备主要是指粮仓内的电子设备和装置,有些设备因气密性不好而无法耐磷化氢气体的熏蒸,在粮仓进行磷化氢杀虫熏蒸作业后会失效或损坏,给监测带来困难,也造成了成本的提高。Phosphine is corrosive to a certain extent, and it is easy to react with metals such as copper or copper alloys to cause metal corrosion. As one of the main materials of electronic equipment and devices, metal copper is widely used, so phosphine is highly corrosive to electronic equipment. With the continuous development of grain storage intelligence and informatization, the granary equipment is also increasing. The granary equipment mainly refers to the electronic equipment and devices in the granary. Some equipment cannot withstand the fumigation of phosphine gas due to poor air tightness. After the phosphine insecticide fumigation operation is carried out in the granary, it will fail or be damaged, which will bring difficulties to monitoring and increase the cost.
基于上述原因,粮食仓储中所使用的电子设备和装置有必要在使用前进行耐熏蒸性的测试,确保电子设备在入仓前满足对熏蒸剂的耐受要求,以避免在使用过程中因为储粮熏蒸操作而造成失效或损坏。另外,对于电子设备和装置的生产厂家,也需要这样的测试装置对产品进行检测,确定产品是否耐熏蒸,以确定产品的防熏蒸研究方向。Based on the above reasons, it is necessary for the electronic equipment and devices used in grain storage to undergo a fumigation resistance test before use to ensure that the electronic equipment meets the fumigant resistance requirements before entering the warehouse, so as to avoid the fumigant during use. Failure or damage caused by grain fumigation operation. In addition, for manufacturers of electronic equipment and devices, such test devices are also needed to test products to determine whether the products are resistant to fumigation, so as to determine the research direction of product fumigation resistance.

为了便于理解本发明,下面结合附图和具体实施例,对本发明进行更详细的说明。附图中给出了本发明的较佳的实施例。但是,本发明可以以许多不同的形式来实现,并不限于本说明书所描述的实施例。相反地,提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
需要说明的是,除非另有定义,本说明书所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是用于限制本发明。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field of the present invention. Terms used in the description of the present invention are only for the purpose of describing specific embodiments, and are not used to limit the present invention. The term "and/or" used in this specification includes any and all combinations of one or more of the associated listed items.
如图1所示,本实施例中该测试装置包括一个测试箱,该测试箱包括一个一端开口的箱体1,开口处装配有与箱体密封配合的盖体2。在测试时,要先将被测设备和熏蒸试剂放入到箱体1内,再将箱体1与盖体2密封装配构成一个测试用的密闭空间,以维持测试所需的浓度,这里的密闭空间能尽量避免在测试过程中由于箱体的气密性不好引起熏蒸气体外泄,从而导致箱体内熏蒸气体浓度不够而在测试过程中需要再往箱体内补充熏蒸试剂的情况出现。当然,该装置还包括用于监测箱体内测试环境信息的测试监测系统,该测试监测系统至少可以监测熏蒸气体的浓度,以实时监测测试过程中是否有熏蒸气体外泄,一旦检测到箱体内有熏蒸气体泄露,造成箱体内熏蒸气体的浓度达不到测试要求,就要及时地往箱体内补充熏蒸试剂。As shown in FIG. 1 , the test device in this embodiment includes a test box, which includes a box body 1 with one end open, and a
本实施例主要是优选目前粮仓熏蒸法中最常用的磷化氢气体来对被测设备进行耐熏蒸测试,密闭空间内磷化氢气体的浓度大于等于500mL/m3。这里的被测设备包括摄像头、粮情系统采集器、湿度传感器、气体传感器、害虫传感器等,由于磷化氢气体对电子设备的腐蚀性较强,因此该测试具有实际意义,也比较实用。In this embodiment, the most commonly used phosphine gas in the granary fumigation method is selected to carry out the fumigation resistance test on the equipment under test. The concentration of phosphine gas in the confined space is greater than or equal to 500mL/m 3 . The tested equipment here includes cameras, grain condition system collectors, humidity sensors, gas sensors, pest sensors, etc. Since phosphine gas is highly corrosive to electronic equipment, this test has practical significance and is more practical.
由于在实际应用中磷化氢气体主要是通过采用磷化铝、磷化锌、磷化钙等和空气中的水分子发生反应来产生获取,本实施例的熏蒸试剂优选磷化铝,而磷化铝一般为固体的粉剂或者片剂,且在反应完成后会留下残渣,为便于处理,可以将磷化铝与被测设备分隔开来,将磷化铝放置在一个独立的小空间内。因此,本实施例在测试箱上设置一个专用于投放磷化铝的投放孔14,且这个投放孔要远小于箱体开口的尺寸,在测试箱的内部再设置一个与该投放孔对应的专用于放置磷化铝的放置盒5,在放置盒的盒壁上设置气体扩散孔6。这里的气体扩散孔6既可以是直径较大的至少一个大孔,也可以是纱网状的多个小孔,其具体结构不受描述方式所限,只要使磷化氢气体能够扩散至整个箱体即可。当然,为了保持箱体内部空间的气密性,投放孔处还装配有与其密封配合的孔盖4。由于磷化氢有剧毒,在箱体内部浓度降低到需要补充磷化铝时,通过这个投放孔进行操作远比打开测试箱的盖体进行操作引起磷化氢气体外泄的量要小的多,那么相对的对人的伤害也就会更小一些,保证操作人员的安全性。Since phosphine gas is mainly generated and obtained by reacting with water molecules in the air by using aluminum phosphide, zinc phosphide, calcium phosphide, etc. in practical applications, the fumigating agent of this embodiment is preferably aluminum phosphide, and phosphorus Aluminum phosphide is generally a solid powder or tablet, and will leave a residue after the reaction is completed. For the convenience of handling, the aluminum phosphide can be separated from the equipment under test, and the aluminum phosphide can be placed in a small independent space. Inside. Therefore, in the present embodiment, a
这里的投放孔14及配套的孔盖4、放置盒既可以设置的箱体1上,也可以设置在盖体2上,其设置的位置不影响测试空间的密封性。另外,用于放置磷化铝的放置盒的结构也是多种多样的,方形结构、圆形或其他不规则的形状均可。Here, the
本发明的测试装置在一个密闭空间内充入测试所需的磷化氢气体(本实施例中磷化氢气体是通过磷化铝与空气中的水分反应而产生的),将被测设备在该密闭空间内放置一段时间,这个时间可以根据测试内容及实际情况而定,达到测试时间后再取出被测设备进行检测,判断其性能参数是否达标。在测试过程中必须实时监测箱体内的测试环境信息,这里主要是磷化氢气体的浓度信息,使其始终保持在测试要求的范围内,一旦发现浓度下降不满足测试所需的浓度要求,就必须立即补充,以保持测试的可靠性。该装置能够很好地模拟粮仓在熏蒸杀虫时的实际环境(主要是浓度环境),对一些易被磷化氢气体腐蚀的设备(包括传感器、采集器等)进行耐熏蒸测试,且在测试时的磷化氢气体浓度比实际粮仓环境的浓度还要高,测试可靠性高,测试结果可信度高。The test device of the present invention is filled with the phosphine gas required for the test in a closed space (in this embodiment, the phosphine gas is produced by the reaction of aluminum phosphide and moisture in the air), and the tested equipment is Place it in the confined space for a period of time. This time can be determined according to the test content and the actual situation. After the test time is reached, the device under test is taken out for testing to determine whether its performance parameters meet the standards. During the test process, the test environment information in the box must be monitored in real time. Here is mainly the concentration information of phosphine gas, so that it is always kept within the range required by the test. Once the concentration drops and does not meet the concentration requirements required for the test, the It must be replenished immediately to maintain the reliability of the test. The device can well simulate the actual environment (mainly concentration environment) of the granary during fumigation and insecticide, and conduct fumigation resistance tests on some equipment (including sensors, collectors, etc.) that are easily corroded by phosphine gas, and in the test The concentration of phosphine gas at the time is higher than the concentration of the actual granary environment, the test reliability is high, and the test results are highly credible.
进一步地,为了更进一步在补加磷化铝时避免磷化氢气体向外扩散,该装置还设置有一个封堵和打开气体扩散孔的封堵机构,该封堵机构在从投放孔向放置盒添加磷化铝时避免使箱体内的磷化氢气体向箱体外泄露。Further, in order to further avoid the outward diffusion of phosphine gas when adding aluminum phosphide, the device is also provided with a blocking mechanism for blocking and opening the gas diffusion hole. When adding aluminum phosphide to the box, avoid the leakage of phosphine gas in the box to the outside of the box.
本实施例磷化铝的投放孔14及与其密封配合的孔盖4是设置在箱体1上的;放置盒5优选一端开口一端封闭的圆筒形结构,其开口端与磷化铝的投放孔14对应,该放置盒5与测试箱1固定连接。如图2所示为封堵机构实施例的结构图(放大图),由该图可知,本实施例的封堵机构包括用于进行转动操作的圆环15和圆环上所设的朝箱体1内部延伸并与放置盒5的侧壁转动吻合装配的堵片,圆环的中心有一个圆孔18,这个圆孔与磷化铝的投放孔14对应,圆环与孔盖4密封配合以保证箱体的气密性;堵片包括连续的圆筒部16和用于在转动到设定位置时覆盖封堵气体扩散孔6的延伸部17,圆筒部16的一端与圆环15一体设置,另一端与延伸部17一体设置。该封堵机构一方面可以实现在添加时防止磷化氢气体外泄;另一方面,该封堵机构的圆环15和圆筒部16相互配合,可以在对箱体密封时进一步增加密封效果。The
本实施例的堵片既可以是与放置盒5的内壁转动吻合装配的结构,也可以与放置盒5的外壁转动吻合装配的结构,两种结构均能够起到在转动时覆盖封堵气体扩散孔6的作用。The blocking piece of this embodiment can be a structure that is rotated and assembled with the inner wall of the
另外,放置盒5与测试箱是固定连接的,其连接的方式也比较多,比如可以通过两个连杆将放置盒5与测试箱的箱体1固连,连杆的一端固定在箱体1的内壁上,另一端与放置盒5下部的侧壁固连(需要避开堵片的位置)。In addition, the
采用上述结构的封堵机构时,为达到封堵目的,需将放置盒5侧壁上所设的气体扩散孔6也进行吻合设计,即气体扩散孔不能全部覆盖放置盒的侧壁,需要在封堵机构转动到一定的位置时能够完全覆盖封堵气体扩散孔。When adopting the blocking mechanism of the above-mentioned structure, in order to achieve the purpose of blocking, the
封堵机构的工作原理:测试过程中一旦监测到箱体内磷化氢气体的浓度下降达不到测试要求的情况,操作人员往箱体1中添加磷化铝时,先操作圆环将其转动到一定的位置,利用堵片封堵住气体扩散孔6,将放置盒5与箱体1的内部空间隔离,此时打开孔盖4添加相应剂量的磷化铝,此时由于箱体内的磷化氢不会通过放置盒5向外扩散,那么泄露出的气体就非常少,这样的结构进一步保障了操作人员的人身安全。The working principle of the plugging mechanism: Once the concentration of phosphine gas in the box is monitored to drop and cannot meet the test requirements during the test, when the operator adds aluminum phosphide to the box 1, first operate the ring to rotate it To a certain position, utilize the blocking sheet to block the
另外,这里的封堵机构不限于上述给出的结构,也可以采取其他的形式,比如将气体扩散孔设置于放置盒侧壁的下部区域内,在上部设置一个通道阀门,在熏蒸测试过程中将通道阀门关闭,阻断磷化氢气体向外溢出,但当从投放孔添加磷化铝并盖设密闭封盖后,通道阀门可以打开使得磷化铝落在放置盒的底部,然后再关闭。采用与上述机构类似的封堵结构均能够实现在补加磷化铝时避免箱体内的磷化氢气体外泄,这里不再一一列举。In addition, the blocking mechanism here is not limited to the structure given above, and other forms can also be adopted, such as setting the gas diffusion hole in the lower area of the side wall of the storage box, and setting a channel valve at the upper part, during the fumigation test process Close the channel valve to prevent the phosphine gas from overflowing, but when aluminum phosphide is added from the delivery hole and the airtight cover is set, the channel valve can be opened so that the aluminum phosphide falls to the bottom of the storage box, and then closed . The use of a plugging structure similar to the above mechanism can prevent the leakage of phosphine gas in the box when aluminum phosphide is added, and will not be listed here.
进一步地,本实施例的测试监测系统包括用于监测箱体内测试环境信息的检测传感器、检测传感器的输出端连接的数据采集模块11,以及数据采集模块11的输出端连接的数据传输模块10,数据传输模块10的输出端用于与监控终端通信互联。这里的检测传感器至少包括设置在箱体内部以检测磷化氢气体浓度值的气体传感器8,数据采集模块11采集气体传感器感应的磷化氢气体浓度值,数据传输模块10将数据采集模块11采集的磷化氢气体浓度数据通信传输至监控终端。Further, the test monitoring system of this embodiment includes a detection sensor for monitoring the test environment information in the cabinet, a
除了气体传感器以外,该测试监测系统的检测传感器还包括设置在箱体内部以检测箱体内部温度值的温度传感器以及检测箱体内部相对湿度值的湿度传感器,以便于测试时实时观察测试环境的温、湿度值。温度传感器和湿度传感器的输出端均与数据采集模块11连接;数据采集模块11还进一步采集温度传感器感应的温度值以及湿度传感器感应的相对湿度值,数据传输模块10对温度值和相对湿度值通信传输至监控终端。In addition to the gas sensor, the detection sensor of the test monitoring system also includes a temperature sensor installed inside the box to detect the temperature inside the box and a humidity sensor to detect the relative humidity inside the box, so as to observe the test environment in real time during the test. temperature and humidity values. The output terminals of the temperature sensor and the humidity sensor are all connected with the
为便于安装及更便于箱体密封,本实施例的温度传感器、湿度传感器采用同时具有两种功能的集成的温湿度传感器7。当然,这里的温度传感器和湿度传感器可以根据实际需要选择,既可以都选用,也可以择一选用。气体传感器8、温湿度传感器7的探测头均固定于箱体1的内侧壁上,输出端通过侧壁上所设的穿孔与箱体外壁上所设的信号采集模块11连接。For the convenience of installation and sealing of the box body, the temperature sensor and the humidity sensor of this embodiment adopt the integrated temperature and
这里的数据采集模块11的输出接口为RS232串口;数据传输模块10采用串口服务器,串口服务器具有串口信号转网络信号的功能,能够将信号采集模块的RS232串口转换成TCP/IP网络接口,实现RS232串口与TCP/IP网络接口的数据双向透明传输,使得信号采集模块能够立即具备TCP/IP网络接口功能,连接网络与监控终端进行数据通信,极大的扩展了气体传感器采集信号的传输距离。监控终端既可以是上位机,也可以是手机、IPAD等移动终端,本实施例的监控终端优选上位机,这里的上位机是指可以直接发出操控命令的监控计算机,屏幕上显示各种信号变化(如浓度,温度,相对湿度)。The output interface of the
进一步地,该测试装置还可以包括对测试箱体内部温度进行调控的温控机构、对测试箱体内部湿度进行调控的干湿调控机构,采用上述机构可以更方便地改变测试的环境条件,比如测试温度和相对湿度,以便更真实地模拟实际使用环境,增加测试的可靠性,也使得测试装置的适用范围更广。这里的温控机构、干湿调控机构实现形式很多,比如温度调节机构可以采用水管调温的方式,在箱体内贯穿穿设一根水管,水管与箱体的结合处进行密封处理,或者在箱体的底部盘设水管组件,利用在水管中通入热水或冷水的方式进行温度调节;湿度调节机构采用在箱体内设置雾化喷头,箱体外设置与雾化喷头连通的加压装置的结构,当需要增加湿度时,将水通入加压装置,再将加压后的水通过雾化喷头喷到箱体内,以增加箱体内的空气湿度,当然也可以采用类似于家用加湿器之类的结构,具体结构这里不再赘述。Further, the test device may also include a temperature control mechanism for regulating the internal temperature of the test box, and a dry-humidity control mechanism for regulating the humidity inside the test box. Using the above-mentioned mechanism can change the environmental conditions of the test more conveniently, such as Test temperature and relative humidity in order to more realistically simulate the actual use environment, increase the reliability of the test, and also make the application range of the test device wider. There are many ways to realize the temperature control mechanism and dry-humidity control mechanism here. For example, the temperature regulation mechanism can adopt the method of water pipe temperature adjustment, and a water pipe is penetrated through the box body, and the junction of the water pipe and the box body is sealed, or in the box. The bottom plate of the body is equipped with a water pipe assembly, and the temperature is adjusted by passing hot water or cold water into the water pipe; the humidity adjustment mechanism adopts the configuration that an atomizing nozzle is installed inside the box, and a pressurizing device connected with the atomizing nozzle is installed outside the box structure, when the humidity needs to be increased, the water is passed into the pressurizing device, and then the pressurized water is sprayed into the box through the atomizing nozzle to increase the air humidity in the box. Of course, it can also be used similar to a household humidifier. The structure of the class, the specific structure will not be repeated here.
进一步地,本实施例的测试监测系统还可以包括对磷化氢浓度值、温度值和/或相对湿度值进行实时显示的监测显示模块,该监测显示模块与数据采集模块电连接,可以设置在测试箱体的外部,将数据采集模块采集的磷化氢浓度值、温度值和/或相对湿度值实时动态地加以显示,增加了测试过程中数据显示和监测的直观性。Further, the test monitoring system of this embodiment may also include a monitoring and display module for real-time display of the phosphine concentration value, temperature value and/or relative humidity value, the monitoring and display module is electrically connected with the data acquisition module, and can be set at On the outside of the test box, the phosphine concentration, temperature and/or relative humidity values collected by the data acquisition module are dynamically displayed in real time, which increases the intuitiveness of data display and monitoring during the test.
另外,该测试装置还包括一个电源12以及用于指示电源模块是否通电的电源指示灯9,电源模块上外置一个与供电电源连接的插头13。本实施例的电源模块优选开关电源,能够将220V的交流电转换为直流电,给装置中的用电设备如气体传感器、信号采集模块、串口服务器等供电,且具有体积较小、重量轻和转换效率高的优点。当然,为了便于直观地观察电源是否通电,该可以设置对应的电源指示灯,有交流电接入时工作指示灯点亮显示。In addition, the test device also includes a
另外,在盖体上设置有手柄3,对盖体的操作更方便。测试箱的箱体采用透明有机玻璃材料制成,重量轻,可直观查看内部情况。箱体1的开口、熏蒸试剂的投放孔14、侧壁上所设的穿孔、封堵机构圆环的中心孔等部位均有橡胶密封圈(图中未示出),以保证装置整体良好的气密性。当然,为了扩展其它功能,也可以根据需要增加相应的功能模块。In addition, a
基于同一构思,本发明还提供了一种使用上述粮仓设备耐熏蒸测试装置的测试方法。如图3所示为本发明提供的粮仓设备耐熏蒸测试方法实施例的流程图,由图3可知,该方法包括如下步骤:Based on the same idea, the present invention also provides a test method using the above-mentioned fumigation test device for granary equipment. As shown in Figure 3, it is a flow chart of an embodiment of the granary equipment fumigation resistance test method provided by the present invention. As can be seen from Figure 3, the method includes the following steps:
步骤S1:测试准备,对被测设备进行性能检测,确定被测试设备的性能参数符合该设备设定指标要求,设备能够正常运转,将性能参数符合设定指标要求的被测设备放入测试箱的箱体1内,将相应剂量的熏蒸试剂投入放置盒内,并密封箱体以确保箱体的气密性。Step S1: Test preparation, perform performance inspection on the equipment under test, confirm that the performance parameters of the equipment under test meet the set index requirements of the equipment, and the equipment can operate normally, put the tested equipment whose performance parameters meet the set index requirements into the test box In the casing 1, put the fumigation reagent of the corresponding dose into the placement box, and seal the casing to ensure the airtightness of the casing.
本实施例中的熏蒸气体优选为为磷化氢气体,熏蒸试剂优选为为磷化铝,磷化铝通过与箱体内空气中的水分反应生成磷化氢气体,本测试中磷化氢浓度的测试要求为大于等于500mL/m3。这里的磷化铝的具体剂量是根据箱体的实际空间大小和测试对浓度的要求进行计算的。另外,本实施例中所进行的测试是对被测设备的不加电测试。The fumigation gas in the present embodiment is preferably phosphine gas, and the fumigant reagent is preferably aluminum phosphide, and aluminum phosphide generates phosphine gas by reacting with moisture in the air in the box, and the concentration of phosphine in this test The test requirement is greater than or equal to 500mL/m 3 . The specific dose of aluminum phosphide here is calculated according to the actual space size of the box and the concentration requirements of the test. In addition, the test performed in this embodiment is a test without power on the device under test.
在测试开始前,首先将装置的电源插头13与220V交流电源接通,通电后电源指示灯9正常显示,测试监测系统正常工作,打开监控终端进行测试箱体内环境数据的采集和实时显示,确保磷化氢气体浓度在安全浓度范围内,本实施例的安全浓度范围为0~0.2mL/m;Before the test starts, at first the
然后,将被测试设备放入测试箱体1内,盖紧盖体2,读取箱体1内的磷化氢气体浓度数据和温湿度数据,记录初始数据;Then, put the device under test into the test box 1, close the
之后,打开投放孔的孔盖4,按照计算浓度要求(不小于500mL/m),投入相应剂量的磷化铝,迅速盖上孔盖4,将投放孔14与箱体1进行密封。Afterwards, open the lid 4 of the injection hole, according to the calculated concentration requirement (not less than 500mL/m), drop into the corresponding dose of aluminum phosphide, cover the lid 4 quickly, and seal the
步骤S2:在测试准备完成后开始测试,通过测试监测系统实时监测箱体1内的测试环境信息,尤其磷化氢气体的浓度信息,以保证测试过程中箱体内的环境信息达到测试要求,并对相关测量数据进行存储记录。Step S2: start the test after the test preparation is completed, and monitor the test environment information in the box 1 in real time through the test monitoring system, especially the concentration information of phosphine gas, so as to ensure that the environment information in the box during the test meets the test requirements, and Store and record related measurement data.
在实际的粮仓环境中,熏蒸杀虫的持续时间一般为一个月,但是进行试验测试时,由于测试的浓度要求较高,就不需要这样长的时间,一般测试5~15天的时间就可以保证测试的准确性了。In the actual granary environment, the duration of fumigation and insecticide is generally one month, but when conducting experimental tests, due to the high concentration requirements of the test, it does not need such a long time, generally 5 to 15 days of testing is enough Guaranteed the accuracy of the test.
本实施例中测试的温度范围为-10℃~40℃,湿度范围为20~80RH。The temperature range tested in this embodiment is -10°C-40°C, and the humidity range is 20-80RH.
在测试过程中对箱体1内的磷化氢气体浓度进行实时监测,一旦发现箱体内的气体浓度达不到测试要求,就需要及时补加磷化铝。补加的过程如下:首先操作封堵机构将放置盒5与箱体1进行气流隔离,然后将所要添加的设定剂量的磷化铝从投放孔14投入放置盒5,之后再将孔盖4与投放孔14密封配合,然后再操作封堵机构将放置盒与箱体实现气流连通,完成磷化铝的补加。During the test, the phosphine gas concentration in the box 1 is monitored in real time. Once it is found that the gas concentration in the box does not meet the test requirements, it is necessary to add aluminum phosphide in time. The supplementary process is as follows: first operate the blocking mechanism to isolate the
步骤S3:达到设定的测试时间后,测试结束,此时首先切断电源12,再打开测试箱的盖体2,并开启实验室的通风装置进行通风散气;Step S3: After the set test time is reached, the test ends. At this time, the
步骤S4:通风一段时间后,在磷化氢气体浓度降至安全浓度范围内后,取出被测设备进行检测,检查其性能参数是否符合设定指标要求,如符合,则认为被测设备耐受磷化氢的熏蒸测试,如不符合,则认为被测设备不耐受磷化氢的熏蒸测试。Step S4: After ventilating for a period of time, after the concentration of phosphine gas drops to the safe concentration range, take out the device under test for testing, and check whether its performance parameters meet the requirements of the set indicators. If so, the device under test is considered to be resistant The fumigation test of phosphine, if it is not met, it is considered that the equipment under test is not resistant to the fumigation test of phosphine.
上述过程中,对箱体内的磷化氢气体浓度数据和温湿度进行实时监测是通过对应的气体传感器8以及温湿度传感器7进行的,各传感器的输出端连接有数据采集模块11,数据采集模块11通过数据传输模块10与上位机连接,这里的数据传输模块优选串口服务器,监控终端优选上位机。In the above process, the real-time monitoring of the phosphine gas concentration data and temperature and humidity in the box is carried out by corresponding gas sensors 8 and temperature and
如图4所示为测试环境信息实时监测流程图,由该图可知,该方法通过软件实现对箱体测试环境的实时监控,利用上位机软件通过TCP/IP网络连接测试装置,首先进行连接测试,确定是否建立连接,连接建立后,实时监测过程如下:As shown in Figure 4 is the flow chart of real-time monitoring of test environment information. It can be seen from the figure that the method realizes real-time monitoring of the test environment of the box through software, and uses the host computer software to connect the test device through the TCP/IP network. First, the connection test is performed. , to determine whether to establish a connection. After the connection is established, the real-time monitoring process is as follows:
上位机发送信号采集指令给串口服务器,再由串口服务器将TCP/IP协议的指令内容转换为RS232接口协议的内容后,再传输给数据采集模块11;The upper computer sends signal acquisition instructions to the serial server, and then the serial server converts the instruction content of the TCP/IP protocol into the content of the RS232 interface protocol, and then transmits it to the
数据采集模块11接收到信号采集指令后,采集气体传感器8和温湿度传感器7感应到的对应信号,再由数据采集模块将采集到的测试环境信号通过串口服务器传输给上位机;After the
上位机对采集到的信号进行解析,得到对应的磷化氢气体浓度数据和温、湿度数据,并对解析出的数据进行显示和记录。The upper computer analyzes the collected signals, obtains the corresponding phosphine gas concentration data and temperature and humidity data, and displays and records the analyzed data.
判断程序是否退出,如果没有则继续上述过程直到用户退出程序。Determine whether the program exits, if not, continue the above process until the user exits the program.
本发明的粮仓设备耐熏蒸测试装置通过测试箱的箱体及与其密封配合的盖体构建了一个局部密封的熏蒸气体环境,该环境模拟实际粮仓内的熏蒸杀虫作业环境,对装置内的被测试设备进行熏蒸测试,该熏蒸气体环境中的熏蒸气体的浓度大于实际的熏蒸杀虫作业环境,并将被测设备在高浓度环境中放置一段足够长的测试时间,取出后进行性能参数检测以确定其耐熏蒸性,保证了测试的可信度。另外,在测试过程中通过测试监测系统实时监测箱体内的测试环境信息,如果出现浓度下降需要补充熏蒸试剂的情况,就从投放孔将熏蒸试剂投入到放置盒内,减少添加过程中熏蒸气体外泄,同时放置盒的使用也避免了熏蒸试剂的反应残渣对箱体内部被测设备的污染,也减少了测试后对测试装置的清理过程,使用较为方便。The granary equipment fumigation resistance test device of the present invention constructs a partially sealed fumigation gas environment through the box body of the test box and the cover body sealingly matched with it. The fumigation test is carried out on the test equipment. The concentration of the fumigant gas in the fumigation gas environment is greater than the actual fumigation and insecticidal operation environment, and the tested equipment is placed in a high-concentration environment for a long enough test time, and the performance parameters are tested after taking it out. Determining its fumigation resistance ensures the reliability of the test. In addition, during the test process, the test environment information in the box is monitored in real time through the test monitoring system. If the concentration drops and the fumigant reagent needs to be replenished, the fumigant reagent is put into the placement box from the delivery hole to reduce the amount of fumigant outside the body during the addition process. At the same time, the use of the placement box also avoids the pollution of the test equipment inside the box by the reaction residue of the fumigation reagent, and also reduces the cleaning process of the test device after the test, which is more convenient to use.
