The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and 2, an embodiment of the present invention provides a humidity building system, including: environmental test chamber 1 and a steam generating mechanism for supplying steam into environmental test chamber 1.
The environmental test chamber 1 may take any suitable existing configuration, and embodiments of the present invention are not limited in this regard.
The steam generation mechanism includes: metal block 2, heating element 3 and water supply pipe 4.
The metal block 2 is arranged on the environment test box 1, and a steam delivery blind hole 201 and a water bearing hole 202 communicated with the steam delivery blind hole 201 are arranged in the metal block 2. The steam delivery blind hole 201 is communicated with the inner space of the environment test chamber 1, and the water bearing hole 202 is positioned outside the environment test chamber 1.
The metal block 2 is made of a material with better heat conduction performance. Furthermore, in order to allow the water in contact therewith to evaporate, the metal block 2 has a melting point at least higher than the evaporation temperature of the water (typically 100 ℃ under normal atmospheric pressure) so as to maintain its physical form when its temperature reaches or even exceeds the evaporation temperature of the water.
The aluminum block, the copper block or the iron block can better meet the two requirements. Therefore, in the present embodiment, the metal block 2 may preferably be any one of an aluminum block, a copper block, or an iron block.
Of course, the embodiment of the invention is not limited thereto. Other metal blocks 2 made of a metal material that can meet the above two requirements are also possible, and the embodiment of the present invention is not limited thereto.
In one embodiment, the metal block 2 is disposed on the environmental test chamber 1 and the steam delivery blind hole 201 is communicated with the internal space of the environmental test chamber 1 in such a manner that the sidewall of the environmental test chamber 1 may be provided with the steam delivery hole 101. The end face of the metal block 2 is attached to the outer wall of the environment test box 1, and the steam delivery blind hole 201 is correspondingly communicated with the steam through hole 101. The set end surface is the end surface where the opening end of the steam delivery blind hole 201 is located.
In this embodiment, the metal block 2 and the environmental test chamber 1 are bonded and fixed face to face. And the steam delivery blind hole 201 is communicated with the setting end surface and corresponds to the steam delivery hole 101 arranged on the side wall of the environment test box 1. Thereby, the communication between the blind steam delivery hole 201 and the internal space of the environmental test chamber 1 is realized.
Thus, the entire metal block 2 is located outside the environmental test chamber 1. So that the water receiving holes 202 provided in the metal block 2 are also located outside the environmental test chamber 1.
In another embodiment, the metal block 2 is disposed on the environmental test chamber 1 and the blind vapor delivery hole 201 may be in communication with the internal space of the environmental test chamber 1 in such a manner that the sidewall of the environmental test chamber 1 may be provided with a mounting hole (not shown). The metal block 2 is arranged in the mounting hole in a penetrating way, and the opening end of the steam transmission blind hole 201 is positioned in the environment test box 1.
In this embodiment, the mounting hole provided on the side wall of the environmental test chamber 1 is adapted to the cross-sectional shape of the metal block 2, so that the metal block 2 is inserted into the mounting hole and fixed. In this way, part of the metal block 2 extends into the interior space of the environmental chamber 1, and another part is located outside the environmental chamber 1. And the water receiving hole 202 is provided in a portion of the metal block 2 located outside the environmental test chamber 1.
The heating assembly 3 is inserted into the metal block 2 and is used for heating the metal block 2 to be heated to a temperature higher than the evaporation temperature of water. The heating assembly 3 may take any suitable existing configuration, such as an electric heating tube, etc., and embodiments of the present invention are not limited in this regard. The heating assembly 3 may be connected to a power source through a relay, and the heating assembly 3 is controlled to start or stop operation by opening or closing the relay.
The metal block 2 may be in a cube shape and be arranged horizontally, and the steam delivery blind hole 201 extends horizontally along the axial direction in the inside. Also, the heating means 3 may be provided in plural to improve the heating efficiency of the metal block 2. Furthermore, a plurality of heating elements 3 surrounds the blind vapour delivery holes 201. Therefore, heat generated by the heating assemblies 3 can be intensively supplied to the steam delivery blind holes 201, and the heat utilization rate is improved.
Further, the plurality of heating assemblies 3 are arranged in a ring-shaped or rectangular array, and the steam delivery blind hole 201 is positioned at the center of the array of the plurality of heating assemblies 3. In this way, the uniformity of heat generation by the plurality of heating elements 3 can be improved.
One end (water outlet end) of the water supply pipe 4 is inserted into the water receiving hole 202, and the other end (water inlet) is used for communicating with a water source. With the above description in mind, the water receiving bore 202 is located outside the environmental test chamber 1. Therefore, the water supply pipe 4 matched with the water bearing hole 202 is also positioned outside the environment test box 1, so that the problem that the water supply pipe 4 is interfered with the environment test box 1 in position is avoided, and the water supply pipe 4 can be smoothly assembled with the metal block 2.
As shown in fig. 2, the water receiving hole 202 is opened upward, its axial direction is perpendicular to the axial direction of the steam delivery blind hole 201, and the water receiving hole 202 is provided at a position away from the open end of the steam delivery blind hole 201. Thus, the water injected into the steam delivery blind hole 201 through the water supply pipe 4 can traverse the steam delivery blind hole 201 as much as possible, so that the water is fully contacted with the metal block 2 to generate steam.
Further, the number of the steam generating mechanisms may be plural, and the plural steam generating mechanisms are uniformly arranged on the environmental test chamber 1. Therefore, the steam generating mechanisms which are uniformly arranged can uniformly supply steam into the environment test chamber 1, so that the cluster phenomenon of the steam in the environment test chamber 1 is reduced, the uniform distribution of the steam in the environment test chamber 1 is improved, and the humidifying uniformity is further improved.
Further, a temperature detecting element 5 may be provided in the metal block 2 for detecting the current actual temperature of the metal block 2. The environment test chamber 1 may be provided with a humidity detection element for detecting the current actual humidity in the environment test chamber 1 in real time.
The temperature detecting element 5 and the humidity detecting element may be of any suitable present construction, and for example, a thermocouple, a humidity sensor, and the like may be used, and the embodiment of the present invention is not limited thereto.
In order to control the humidity in the environmental test chamber 1, the embodiment of the invention also provides a humidity control method which comprehensively considers two factors of the temperature of the metal block 2 and the humidity in the environmental test chamber 1. Thereby, the heating element 3 is prevented from being damaged due to the excessively high temperature of the metal block 2 while controlling the humidity in the environmental test chamber 1.
Specifically, as shown in fig. 3, the humidity control method according to the embodiment of the present invention includes:
First PID calculation: and performing first PID calculation on the humidity deviation value of the set humidity SP_humidity and the current actual humidity PV_humidity in the environment test chamber 1, and outputting a first parameter PID_Out1.
The current actual humidity pv_humidity in the environmental test chamber 1 can be measured by the humidity detection element described above, and the humidity sp_humidity is set in advance and stored locally.
The first PID calculation may be performed by a first PID Controller pid_controller 1. The proportional coefficient Kp, the differential coefficient Ki and the integral coefficient Kd involved in the proportional, integral and differential control process in the first PID calculation are suitable for adjustment and setting according to practical situations, which is not limited in the embodiment of the present invention.
Second PID calculation: and performing second PID calculation on the set maximum temperature SP_temperature of the metal block 2 and the temperature deviation value of the current actual temperature PV_temperature of the metal block 2 to obtain a second parameter PID_Out2.
Likewise, the current actual temperature pv_temperature of the metal block 2 can be measured by the temperature detection element 5 described above. The set maximum temperature sp_temperature of the metal block 2 is a temperature value selected from the temperature range defined above that of the evaporation temperature of water but below the melting temperature thereof.
Since this second PID calculation is mainly used to prevent the temperature of the metal block 2 from being too high to cause damage to the heating element 3, the maximum temperature of the metal block 2 is set not to be higher than the withstand limit temperature of the heating element 3. For example, the heating assembly 3 is an electric heating tube, the withstand limit temperature of which is 250 ℃. The set maximum temperature SP_temperature of the metal block 2 is arbitrarily selected within the temperature range of 100-250 ℃.
The current actual temperature pv_temperature of the metal block 2 is set, i.e. it can be stored locally. After the temperature detecting element 5 measures the current actual temperature pv_temperature of the metal block 2, the set maximum temperature sp_temperature of the metal block 2 is called, and the second PID calculation can be performed.
Likewise, the second PID calculation may be performed by a second PID Controller PID_Controler2. The proportional coefficient Kp, the differential coefficient Ki and the integral coefficient Kd involved in the proportional, integral and differential control process included in the second PID calculation are suitable for adjustment and setting according to practical situations, which is not limited in the embodiment of the present invention.
Selecting target parameters: the minimum value of the output of the two PID calculations is selected by using a function Min (PID_Out1, PID_Out2), and the relatively smaller value of the first parameter PID_Out1 and the second output parameter PID_Out2 is assigned to the target parameter PID_OutMin.
PWM pulse output: according to the value of the target parameter pid_out_min, a PWM pulse train of a corresponding width is output and supplied to a relay controlling the connection with the heating assembly 3. The relay is driven by the PWM pulse train to turn on or off the connection between the heating assembly 3 and the power supply.
In this embodiment, the target parameter pid_out_min may be a duty cycle of PWM (Pulse Width Modulation) pulse trains, which is combined with the signal period T of the PWM pulse trains to obtain the width of the PWM pulse trains. For example, if the target parameter pid_out_min is 0.5 and the signal period T of the PWM pulse train is 4s, the width of the PWM pulse train is 0.5×4s=2s.
The PWM pulse train controls the on-off of the relay so as to control the actual working time of the heating component 3, thereby realizing the control and adjustment of the output power of the heating component 3.
Therefore, through the operation and output of the two PIDs, on one hand, normal humidity control is ensured, and on the other hand, the heating component 3 is also protected to prevent damage caused by overhigh temperature.
Based on the same conception, the embodiment of the invention also provides a humidity control device, as described in the following embodiment. Because the principle of the humidity control apparatus for solving the problem and the technical effect that can be obtained are similar to those of the humidity control method, the implementation of the humidity control apparatus can be referred to the implementation of the humidity control method, and the repetition is not repeated. The term "module" used below may be implemented on a software basis, may be implemented on a hardware basis, or may be implemented in a combination of software and hardware.
As shown in fig. 4, the humidity control apparatus according to the embodiment of the present invention includes:
The first PID calculation module 100 is configured to perform a first PID calculation on the humidity deviation value of the set humidity and the current actual humidity in the environmental test chamber 1, and output a first parameter;
the second PID calculation module 200 is configured to perform a second PID calculation on the set maximum temperature of the metal block 2 and a temperature deviation value of the current actual temperature of the metal block 2, so as to obtain a second parameter; the set maximum temperature of the metal block 2 is not higher than the tolerance limit temperature of the heating component 3;
A target parameter selection module 300, configured to take a relatively smaller value of the first parameter and the second output parameter as a target parameter;
The PWM pulse output module 400 is configured to output a PWM pulse train with a corresponding width according to the target parameter, and provide the PWM pulse train to a relay connected to the heating assembly 3, where the relay is driven by the PWM pulse train to turn on or off the connection between the heating assembly 3 and the power supply.
The humidity control device in the embodiment of the present invention corresponds to the above humidity control method, and may have the same technical effects as those of implementing the humidity control method, and will not be described herein.
It should be noted that, in the description of the present invention, the terms "first," "second," and the like are used for descriptive purposes only and to distinguish between similar objects, and there is no order of preference between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
