Description

一种粮仓设备耐熏蒸测试装置和方法A granary equipment fumigation resistance test device and method

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.

具体实施方式Detailed ways

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 cover body 2 sealingly fitted with the box body at the opening. During the test, the device under test and the fumigation reagent should be put into the box 1 first, and then the box 1 and the cover 2 are sealed and assembled to form a closed space for testing to maintain the concentration required for the test. Here The confined space can avoid the leakage of fumigant gas due to the poor airtightness of the box during the test, resulting in insufficient fumigant gas concentration in the box and the need to replenish fumigation reagents into the box during the test. Of course, the device also includes a test monitoring system for monitoring the test environment information in the box. The test monitoring system can at least monitor the concentration of fumigant gas, so as to monitor in real time whether there is leakage of fumigant gas during the test. If the fumigant gas leaks, causing the concentration of the fumigant gas in the box to fail to meet the test requirements, it is necessary to replenish the fumigant reagent in the box in time.

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 delivery hole 14 dedicated to putting in aluminum phosphide is set on the test box, and this delivery hole will be far smaller than the size of the opening of the box body, and a dedicated delivery hole corresponding to the delivery hole is set inside the test box. For the placement box 5 where aluminum phosphide is placed, gas diffusion holes 6 are provided on the box wall of the placement box. The gas diffusion hole 6 here can be at least one large hole with a larger diameter, or a plurality of small holes in gauze shape, and its specific structure is not limited by the description, as long as the phosphine gas can be diffused to the entire Just the box. Of course, in order to maintain the airtightness of the inner space of the box body, a hole cover 4 sealingly fitted with the delivery hole is also equipped. Because phosphine is highly toxic, when the concentration inside the box is reduced to the point where aluminum phosphide needs to be supplemented, the amount of phosphine gas leakage caused by the operation through this injection hole is much smaller than that of opening the lid of the test box. , then the relative harm to people will be smaller, ensuring the safety of operators.

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 injection hole 14 and the supporting hole cover 4 and the placement box can be arranged on the casing 1 or the cover body 2, and the position of the arrangement does not affect the airtightness of the test space. In addition, the structure of the placement box for placing aluminum phosphide is also various, and square structure, circle or other irregular shapes are all available.

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 insertion hole 14 of the aluminum phosphide of the present embodiment and the hole cover 4 that is sealingly matched with it are arranged on the casing 1; Corresponding to the hole 14 , the placement box 5 is fixedly connected with the test box 1 . As shown in Figure 2, it is a structural diagram (enlarged view) of the embodiment of the blocking mechanism. As can be seen from this figure, the blocking mechanism of the present embodiment includes a circular ring 15 for rotating operation and a facing box set on the circular ring. The inside of the body 1 is extended and rotated to coincide with the side wall of the storage box 5. There is a round hole 18 in the center of the ring. This round hole corresponds to the injection hole 14 of aluminum phosphide. The ring is sealed with the hole cover 4. To ensure the airtightness of the box; the blocking piece includes a continuous cylindrical portion 16 and an extension portion 17 for covering and blocking the gas diffusion hole 6 when it is rotated to the set position, and one end of the cylindrical portion 16 is connected to the ring 15 It is integrally arranged, and the other end is integrally arranged with the extension part 17 . On the one hand, the blocking mechanism can prevent the leakage of phosphine gas when adding; on the other hand, the ring 15 and the cylindrical part 16 of the blocking mechanism cooperate with each other to further increase the sealing effect when sealing the box.

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 storage box 5, and can also be a structure that is rotated and assembled with the outer wall of the storage box 5. Both structures can cover the diffusion of blocking gas during rotation. The role of hole 6.

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 placement box 5 is fixedly connected to the test box, and there are many ways to connect it. For example, the placement box 5 and the box body 1 of the test box can be fixedly connected by two connecting rods, and one end of the connecting rod is fixed on the box body. 1, the other end is fixedly connected with the side wall of the placement box 5 bottom (need to avoid the position of the blocking sheet).

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 gas diffusion hole 6 set on the side wall of the storage box 5 must also be designed in accordance with each other, that is, the gas diffusion hole cannot completely cover the side wall of the storage box, and it needs to When the blocking mechanism rotates to a certain position, it can completely cover the blocking gas diffusion hole.

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 gas diffusion hole 6, and place the box 5 to isolate the inner space of the casing 1, and open the hole cover 4 to add corresponding doses of aluminum phosphide. Hydrogen hydride will not diffuse outwards through the placement box 5, so the leaked gas is very little, and such a structure further ensures the personal safety of operators.

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.

The detection sensor here at least includes the gas sensor 8 that is arranged inside the box to detect the phosphine gas concentration value, the data acquisition module 11 collects the phosphine gas concentration value induced by the gas sensor, and the data transmission module 10 collects the phosphine gas concentration value by the data acquisition module 11. The phosphine gas concentration data communication is transmitted to the monitoring terminal.

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 data acquisition module 11; the data acquisition module 11 further collects the temperature value sensed by the temperature sensor and the relative humidity value sensed by the humidity sensor, and the data transmission module 10 communicates the temperature value and the relative humidity value transmitted to the monitoring terminal.

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 humidity sensor 7 which has two functions at the same time. Of course, the temperature sensor and the humidity sensor here can be selected according to actual needs, both can be selected, or one can be selected. The detection heads of the gas sensor 8 and the temperature and humidity sensor 7 are all fixed on the inner wall of the box body 1, and the output ends are connected with the signal acquisition module 11 set on the outer wall of the box through the perforation provided on the side wall.

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 data acquisition module 11 here is an RS232 serial port; the data transmission module 10 adopts a serial port server, and the serial port server has the function of converting a serial port signal to a network signal, and can convert the RS232 serial port of the signal acquisition module into a TCP/IP network interface to realize RS232 The two-way transparent transmission of data between the serial port and the TCP/IP network interface enables the signal acquisition module to immediately have the TCP/IP network interface function, connect the network and the monitoring terminal for data communication, and greatly expand the transmission distance of the gas sensor acquisition signal. The monitoring terminal can be a host computer, or a mobile terminal such as a mobile phone or an IPAD.

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 power plug 13 of the device is connected to the 220V AC power supply. After power-on, the power indicator light 9 normally displays, and the test monitoring system works normally. The concentration of phosphine gas is within the safe concentration range, and the safe concentration range of this embodiment is 0~0.2mL/m;

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 storage box 5 from the box body 1 by air flow, then put the aluminum phosphide of the set dose to be added into the storage box 5 from the delivery hole 14, and then place the hole cover 4 It is sealed and matched with the delivery hole 14, and then the blocking mechanism is operated to realize airflow communication between the placement box and the box body, and the addition of aluminum phosphide is completed.

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 power supply 12 is first cut off, and then the cover 2 of the test box is opened, and the ventilation device in the laboratory is turned on to ventilate and disperse air;

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.
