The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides an aging test apparatus for a photoelectric coupler, including a control module 110 and an aging box 120, the aging test system further includes: the temperature sensor 130 is disposed in the burn-in box 120 and connected to the control module 110, and the temperature sensor 130 is configured to acquire temperature data of a designated area in the burn-in box 120 and send the temperature data to the control module 110. A data transmission module 140, wherein the data transmission module 140 is connected to the control module 110. And the cooling device 190 is arranged on the aging box 120, and the cooling device 190 is connected with the control module 110. The remote terminal 150, the remote terminal 150 includes a remote display unit 151, a remote data processing unit 152, a remote interaction unit 153 and a remote storage unit 154, the remote display unit 150 is connected to the remote data processing unit 152, the remote interaction unit 153 is connected to the remote data processing unit 152, the remote storage unit 154 is connected to the remote data processing unit 152, and the remote data processing unit 152 is in communication connection with the control module 110 through the data transmission module 140. The remote display unit 150 is used to display the data information received and transmitted by the remote data processing unit 152. The remote interaction unit 153 is used for interacting with the remote data processing unit 152. The remote storage unit 154 stores data information and the like received by the remote data processing unit 152. The remote data processing unit 152 is used for receiving data information and transmitting data information, and processing related data information. The control module 110 includes a temperature-rise-rate calculation unit 111, a comparison unit 112, and an instruction processing unit 113, where the temperature-rise-rate calculation unit 111 is configured to calculate a temperature-rise rate according to temperature data. The rate of temperature rise can be calculated using existing algorithms. For example, the temperature increase rate can be calculated from the temperature difference per unit time. The comparing unit 112 is configured to compare the temperature data with a threshold temperature, and compare the temperature-rising rate with a threshold speed, and when the temperature-rising rate is greater than or equal to the first threshold speed and the temperature data is less than the threshold temperature, the instruction processing unit 113 of the control module 110 sends alarm information to the remote terminal 150 through the data transmission module 140, and turns on the cooling device 190.
When the system is in use, the control module 110 acquires temperature data of a designated area in real time through the temperature sensor 130, compares the acquired temperature data with a threshold temperature, when the temperature of some areas in the aging box 120 of the system is abnormal, the control module 110 sends alarm information to the remote terminal 150 through the data transmission module 140, and an attendant can acquire relevant information through the remote terminal 150 and can take measures to avoid fire.
The system not only simply judges whether to alarm according to the threshold temperature. But rather a combination of both threshold temperature and rate of rise. Because if the temperature rise rate of some area is abnormal under the condition of less than the threshold temperature, the temperature data detected by the temperature sensor 130 may not exceed the threshold temperature, but at this time, the area is in a dangerous state. If no action is taken, or close observation is made, a fire may be triggered. At this time, it is necessary to send alarm information to the remote terminal 150 to attract the attention of the relevant person.
The designated region is a region near the sample of the photocoupler. That is, the temperature sensor 130 is installed near the photocoupler sample for monitoring the temperature of the area. The number of temperature sensors 130 may be determined according to the number of samples and the distribution area.
The cooling device 190 may be a ventilator, such as a fan. Other types of cooling devices are also possible. The effect of cooling is achieved.
The remote terminal 150 may be various types of terminal devices such as a mobile phone, a tablet computer, and a desktop computer. The remote terminal 150 is used to obtain and display information sent by the data transmission module 140. Further, the control command may also be sent to the control module 110 through the data transmission module 140.
The data transmission module 140 may be a wired data transmission module or a wireless data transmission module. For example, a WIFI module, a GSM module, etc.
The threshold temperature may be selected according to actual conditions, and for example, the threshold temperature may be set to 75 ℃. It will be appreciated that the threshold temperature may be set to other temperatures.
The form of the alarm information may take the form of information in the prior art. For example, when the remote terminal 150 is a mobile phone, the alarm information may be sent to the mobile phone in a short message.
In this embodiment, the aging test system further includes a human-computer interaction module 160, where the human-computer interaction module 160 is connected to the control module 110 and configured to interact with the control module 110. For example, the threshold temperature may be set by the human interaction module. Further, the human-computer interaction module 160 may have an operation interface, and control the aging test system through the human-computer operation interface, and may perform data interaction in a form of a graph or the like.
In this embodiment, when the temperature data is greater than or equal to the threshold temperature, the instruction processing unit 113 sends a power-off instruction to the power supply 180. Or, when the temperature data is greater than or equal to the threshold temperature, continuously determining whether the temperature-increasing speed is greater than or equal to a second threshold speed, and only when the temperature-increasing speed is greater than or equal to the second threshold speed, the instruction processing unit 113 sends the power-off instruction to the power supply 180. By the arrangement, when the power supply 180 receives the power-off signal, the power can be automatically cut off. Thereby avoiding the occurrence of fire. The threshold temperature, the second threshold speed and the first threshold speed can be set according to actual conditions.
Further, during the above setting, when the temperature data is greater than or equal to the threshold temperature, it is continuously determined whether the temperature rising speed is greater than or equal to the second threshold speed, and only when the temperature rising speed is greater than or equal to the second threshold speed, the instruction processing unit 113 sends the power-off instruction to the power supply 180. This arrangement can prevent the power-off operation from being performed without power-off in some cases. For example, when the threshold temperature is set to be less reasonable, such as relatively low, even if the temperature data is greater than the threshold temperature, a dangerous situation such as a fire may not occur in the event of activation of the temperature lowering device. At this time, it is necessary to determine whether the temperature data is greater than the threshold temperature, and the cooling device can control the temperature so that the temperature does not rise rapidly, or steadily falls after rising for a period. If the effect can be achieved, power-off is not needed, so that the experiment can be ensured to be continuously carried out, and meanwhile, dangerous conditions such as fire disasters can be avoided.
The following illustrates the above two cases.
For example, the temperature rise speed and the current temperature need to be considered comprehensively, when the measured temperature does not exceed the threshold temperature, if the temperature rise speed is greater than 10 degrees/second, early warning and ventilation are needed, the temperature rise is displayed to be too fast, meanwhile, information is sent to workers, the current temperature is monitored in real time, and once the temperature exceeds the threshold temperature, the power supply is cut off immediately.
For example, when the measured temperature exceeds the threshold temperature, it can be determined whether the power needs to be cut off by determining whether the temperature rise speed is greater than a second threshold speed, for example, when the temperature rise speed is less than 5 degrees/second, which indicates that no fire occurs, the ventilation device can be turned on to reduce the temperature, and the temperature rise speed is monitored in real time, and when the temperature rise speed cannot be controlled by ventilation, that is, when the temperature rise speed is greater than or equal to 5 degrees/second, the power should be cut off immediately.
Furthermore, on the basis, a camera device can be arranged and used for shooting the condition in the aging box, and the camera device can be connected with the control module. When the temperature is abnormal or the temperature rise speed is abnormal, the camera device can be started to capture a picture of the abnormal area, and the picture is sent to the remote terminal.
In this embodiment, the aging test system further includes an alarm module 170, the alarm module 170 is connected to the control module 110, when the temperature data is greater than or equal to the threshold temperature, or when the temperature data is greater than or equal to the threshold temperature and the temperature rise speed is greater than or equal to a second threshold speed, the second threshold speed is greater than the first threshold speed, the instruction processing unit 113 sends a trigger instruction to the alarm module 170, and the alarm module 170 starts an alarm mode after receiving the trigger instruction. The alarm module 170 may be a sound and light alarm module 170. The alarm module 170 can give an alarm to attract the attention of the relevant personnel. By means of the arrangement, on one hand, the remote terminal 150 of the attendant can receive alarm information, and on the other hand, auxiliary measures such as sound and light alarm can be taken to attract the attention of the relevant attendant. The safety of the aging test system is effectively improved by combining the dual measures.
In this embodiment, the control module 110 receives a power control instruction sent by the remote terminal 150 through the data transmission module 140, and controls the power supply 180 to be turned on or off according to the control instruction. Thus, the person on duty can be given the option. Whether the power supply needs to be turned off or not can be judged according to the related alarm information, and if the power supply needs to be turned off, a control instruction can be sent by the remote terminal 150 to turn off the power supply. After power is turned off, remote terminal 150 may also send a command to turn power back on. It can be understood that, when the remote terminal 150 is a mobile phone, the sending of the control instruction can be realized by a mobile phone short message or an APP on the mobile phone. Specifically, according to a pre-programmed program instruction, a short message with corresponding content may be sent to the remote terminal 150 according to a test condition, that is, the content of the short message has an interactive function. Meanwhile, the operator on duty can reply according to the short message content, the control module 110 can execute corresponding instructions according to the reply content and the current state of the test system, and when the reply content is incorrect, the short message can prompt that the reply content is wrong. Thereby correctly realizing the action of remotely switching on and off the power supply.
In this embodiment, the control module 110 sends the test data and the test status of each sample in the burn-in box 120 to the remote terminal 150 through the data transmission module 140. The test state refers to whether the test sample is in the test or is out of the test after the test is finished. The test data and test status may be transmitted to remote terminal 150 in various forms. For example, the message can be sent to the mobile phone of the person on duty in a short message mode. Further, the test data and the test status may be transmitted to the remote terminal 150 of the attendant in the form of a chart or the like.
In this embodiment, when the sample reaches the test ending condition, the control module 110 sends the test completion information to the remote terminal 150 through the data transmission module 140. By the arrangement, the operator on duty can know which samples are tested at first time. So that the person on duty can take the next operation at the first time.
It will be appreciated that the above information may also be transmitted to remote terminal 150 in a variety of ways. For example, the message may be sent by a short message. Or may be sent in a graphical or other manner.
