Description

Technical Field

[0002] After the production and assembly of electrical products such as industrial equipment AC three-phase power supply voltage and current collectors are completed, the collectors need to be powered on and tested for aging. Power-on testing is to test whether the collector works normally and whether the three-phase voltage and current are measured accurately when the collector circuit is powered on and a three-phase AC signal is applied. Aging testing is to place the collector in a high-temperature environment and continuously power it on to test whether it still works normally after being powered on for a long time in a high-temperature environment.

[0003] Traditionally, power-on testing is to manually operate a multimeter to test the circuit board function. The computer is used to read the three-phase AC voltage and current values ​​through the collector communication port to determine whether the collector is working normally. This method is very inefficient and is prone to failure to detect abnormal data from the collector due to human negligence, resulting in missed detection. Traditional aging is to power on the equipment in a high-temperature aging room, and then manually access the communication line one by one to read the data to determine whether it is normal. The process is relatively cumbersome, wiring is prone to errors, and the efficiency is very low. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] This embodiment provides a device aging detection device, such as Figure 1 As shown, it includes: a constant temperature box 1, multiple controllers 2, a heater 3, a temperature sensor 4 and an industrial computer 5.

[0029] like Figure 1As shown, the device to be detected, each controller 2, the temperature sensor 4 and the heater 3 are all arranged in the constant temperature box 1, and the industrial computer 5 is arranged outside the constant temperature box 1; the input end of each device to be detected inputs the same test signal, the output end of each device to be detected is respectively connected to the first end of a controller 2, and each device to be detected is used to start working based on the test signal; the second end of each controller 2 is connected to the first end of the industrial computer 5, and the controller 2 is used to store the working data of the corresponding device to be detected when it is working.

[0030] like Figure 1 As shown, the second end of the industrial computer 5 is connected to the heater 3, and the output end of the industrial computer 5 outputs the detection result; the temperature sensor 4 is connected to the third end of the industrial computer 5, which is used to collect temperature information in the constant temperature box 1 and send the temperature information to the industrial computer 5; the industrial computer 5 is used to control the heater 3 to heat the inside of the constant temperature box 1, and adjust the temperature of the heater 3 based on the temperature information so that the inside of the constant temperature box 1 maintains a constant temperature, and after the first preset time, each controller 2 obtains the working data of each device to be detected, and then generates a detection result.

[0031] Specifically, Figure 1 In the process, the industrial computer 5 controls the heater to start heating the inside of the thermostat 1 according to the preset temperature. When the temperature information returned by the temperature sensor to the industrial computer reaches the preset temperature, each device to be tested is powered on based on the test signal and starts to work continuously at the current temperature for the first preset time. Each controller 2 respectively collects and stores the state information and working state data of the corresponding device to be tested when it is working. After the first preset time, the industrial computer obtains the working state information and working state data of each device to be tested at the current temperature and within the first preset time through each controller 2, thereby determining the aging degree of each device to be tested and generating the test results.

[0032] For example, Figure 1 In the above, the industrial computer 5 can collect the current, voltage, temperature, output power, vibration frequency and other data of the equipment to be tested when working in the constant temperature box 1 through each controller 2, and compare them with the pre-stored standard working data of the equipment to be tested when it leaves the factory, and infer the aging degree of each equipment to be tested according to the comparison result. The above detection method is only described by taking a detection method in the prior art as an example, and is not limited to this.

[0033] For example, Figure 2 As shown, the detection equipment can be a collector for measuring the AC three-phase power supply voltage and current of industrial equipment. At this time, the test signal is a three-phase AC signal. Each collector is evenly arranged in the constant temperature box 1, with regular arrangement and compact structure. Multiple controllers are also arranged in the constant temperature box 1, and one controller is connected to one collector.

[0034] It should be noted that the method in which the industrial computer 5 obtains the working data of the device to be detected through the controller 2 and adjusts the temperature of the heater 3 according to the temperature information returned by the temperature sensor 4 are both prior arts and will not be described in detail here.

[0035] Exemplarily, the detection result can be output to an external device through the industrial computer 5, or can be displayed on the industrial computer.

[0036] Exemplarily, the second end of each controller 2 is connected to the first end of the industrial computer 5 via a 485 communication bus.

[0037] In the equipment aging detection device provided in this embodiment, the industrial computer controls the heating of the heater and adjusts the temperature of the heater through the temperature data returned by the temperature sensor, so that a constant temperature is maintained in the constant temperature box; the industrial computer can obtain the working status data of a device to be detected under the test signal and the set temperature through multiple controllers, thereby improving the degree of automation of the test, improving the test efficiency, avoiding missed detection and false detection due to manual detection, and improving the accuracy of the detection.

[0038] In some optional embodiments, such as Figure 3 As shown, the equipment aging detection device also includes: a constant temperature controller 6, a first end of which is connected to the second end of the industrial computer 5, and a second end of which is connected to the heater 3. It is arranged outside the constant temperature box 1. The industrial computer 5 uses the constant temperature controller 6 to adjust the temperature of the heater 3 based on the temperature information, so that the inside of the constant temperature box 1 maintains a constant temperature.

[0039] Specifically, Figure 3 In the process, the industrial computer 5 controls the heater to maintain a constant temperature through the thermostat controller 6, so that the temperature in the thermostat box 1 is maintained at a preset value. The industrial computer 5 does not need to repeatedly adjust the temperature of the heater 3 to keep the temperature of the thermostat box 1 constant, thereby improving the degree of automation of the device and making the detection process more convenient.

[0040] For example, Figure 3 In the embodiment, the industrial computer 5 can calculate the difference between the preset temperature and the actual temperature in the thermostat box 1 by reading the temperature information returned by the temperature sensor 4, and then input the difference into the thermostat controller 6, so that the thermostat controller 6 outputs a temperature adjustment signal according to the difference to adjust the output temperature of the heater, so that the thermostat box 1 is maintained at the preset temperature. The above thermostat adjustment method is only described by taking a temperature adjustment method in the prior art as an example, and is not limited thereto.

[0041] It should be noted that the operator can manually set the temperature on the thermostatic controller 6 or set the temperature of the thermostatic controller 6 through an industrial computer.

[0042] In some optional embodiments, such as Figure 3As shown, the device aging detection device also includes: a humidity detector 7 and a signal source 8, wherein the humidity detector 7 is connected to the fourth end of the industrial computer 5, and is arranged in the constant temperature box 1, and is used to detect the humidity in the constant temperature box 1; the signal source 8 is connected to the input end of each device to be detected, and is used to provide a test signal for each device to be detected.

[0043] Specifically, Figure 3 In the process, the industrial computer 5 monitors the humidity in the constant temperature box in real time through the humidity detector 7. When the humidity is too high, the operator performs dehumidification treatment in the constant temperature box to prevent the insulation degree of the equipment to be tested from being reduced when the humidity is too high, thereby affecting the test results. The signal source is used to provide working power for the equipment to be tested.

[0044] It should be noted that the signal source can output various forms of power supply signals such as AC signals and DC signals, and the specific output signal form is consistent with the demand of the device to be detected for working power supply.

[0046] For example, Figure 3 In the process, the communication device can send the test results to the terminal, and the operator can remotely receive the test results or remotely control the industrial computer 5 through the terminal. The control content includes: controlling the power on or off of the equipment to be tested, controlling the printer 9 to print the test results, adjusting the preset temperature of the constant temperature box 1, etc.

[0047] It should be noted that those skilled in the art can connect display devices, sound devices and other equipment to the output end of the industrial computer according to actual needs, so as to display, broadcast and other processing the detection results of the industrial computer.

[0048] This embodiment provides a detection system, such as Figure 4 As shown, it includes: an industrial computer 5 of the first aspect and multiple constant temperature boxes 1, multiple controllers 2, multiple heaters 3 and multiple temperature sensors 4, wherein the industrial computer 5 has a first end connected to the second end of each controller 2, a second end connected to each heater 3, and a third end connected to each temperature sensor 4; the industrial computer 5 is used to set the temperature in the corresponding constant temperature box 1 through each heater 3, and adjust the temperature of the corresponding heater 3 based on the temperature information returned by each heater 3, so that a constant temperature is maintained inside each constant temperature box 1, and after obtaining the working data of each device to be detected after a first preset time, a detection result is generated.

[0049] Specifically, Figure 4 In the present invention, the detection system includes multiple constant temperature boxes 1, each constant temperature box 1 includes multiple controllers 2, multiple devices to be detected, a heater 3 and a temperature sensor 4. When the devices to be detected start to work based on the test signal, the industrial computer 5 can perform aging detection on the devices to be detected in multiple constant temperature boxes 1 at the same time through each controller 2.

[0050] In the detection system provided in this embodiment, the industrial computer can perform aging tests on the devices to be detected in multiple constant temperature boxes without manual intervention, thereby improving the degree of automation of the detection and improving the detection efficiency.
