[0053] In the POE switch system, the device that provides power is called the power supply equipment (PSE, Power Sourc ingEquipment), and the device that uses the power is called the powered device (PD, Power Device, i.e. load). The main device for Ethernet power supply is PSE, which is responsible for the detection, classification, power-on, and circuit break detection of PD. Once a PD is loaded, PSE will immediately detect the access of PD and cut off the power supply when it is removed. PSE also provides overcurrent protection to prevent PSE and PD from being damaged. The power supply equipment PSE can only provide one usage, but the powered device PD must be able to adapt to two situations at the same time.

[0054] In order to meet the above requirements, this application combines the automation of temperature box control, power supply equipment control, and flow instrument control, and uses POE power supply technology. Through specific testing processes and technical means, it can conduct comprehensive and efficient reliability testing of POE switches. By adopting an automated approach, human intervention and operating errors can be reduced, various actual application scenarios can be accurately simulated, the performance of switches under harsh climatic conditions and special power supply environments can be detected, and potential problems and hidden faults of POE switches can be discovered in a timely manner, providing strong support for the quality assurance and performance optimization of POE switches. In other words, this application provides a set of methods for comprehensively detecting the reliability and stability of POE switches, which can accurately, efficiently, and comprehensively carry out automated testing to ensure that POE switches can maintain reliable performance in different application scenarios.

Exemplarily, the automated testing system of the POE switch includes: a flow meter, a temperature and humidity control box, a controller, a power supply device and an electronic device; the controller controls the connection between the flow meter, the temperature and humidity control box and the power supply device; the power supply device is used to provide the power supply voltage required by different test networks; specifically responds to the voltage control instruction of the controller to control the power supply voltage of the power supply device; the flow meter is used to set the flow parameters; responds to the parameter control instruction of the controller to control the flow parameters of the flow meter; the temperature and humidity control box is used to provide an environment with a certain temperature and / or humidity required by different test networks, responds to the temperature and humidity control instruction of the controller The controller is used to control the temperature and / or humidity in the temperature and humidity control box; the electronic device includes at least one POE switch; the electronic device is placed in the temperature and humidity control box, responds to the configuration instructions of the controller, and configures the test conditions of the electronic device, the test conditions include different combinations of no-load / load, serial / parallel, single machine / multiple machines; the controller sets up a variety of different test networks according to the power supply voltage, flow parameters, temperature and / or humidity and test conditions, and performs long-term flow test through the automated test system of the POE switches of different test networks; and analyzes the serial port data of the electronic device to obtain the test results.

[0057] The present application automatically controls the temperature and humidity control box, flow meter, and power supply equipment, and determines different test conditions according to the power supply voltage, flow parameters, temperature and / or humidity, and test conditions to match different test networks; the POE switch prototype is subjected to long-term flow tests and switch tests such as no-load, loaded, serial, parallel, and multi-machine tests under different climatic environments, thereby improving the reliability of POE switch testing and the diversity of test functions.

[0058] The present application determines different test conditions according to the power supply voltage, flow parameters, temperature and / or humidity and test conditions, that is, at least six tests can be performed, namely, a no-load serial flow test of a POE switch under a reliability climate environment (dual temperature and dual pressure), a no-load dual-machine serial flow test of a POE switch under a reliability climate environment (dual temperature and dual pressure), a no-load parallel flow test of a POE switch under a reliability climate environment (dual temperature and dual pressure), a serial flow test of a POE switch under a reliability climate environment (alternating humidity and heat), a load parallel flow test of a POE switch under a reliability climate environment (temperature cycle), and a POE switch power on and off test under a reliability climate environment (temperature cycle).

The present application can perform long-term flow testing and power-on and power-off automation testing on POE switches under different climatic environments, such as no-load, loaded, serial, parallel, and multi-machine. The flow meter adopts Spirent Communications' instrument for network communication convergence testing. The POE switches placed in the temperature and humidity control box have 1-24 ports of GE Gigabit ports and 25-28 ports of XS 10 Gigabit ports. The operating ambient temperature of the POE switch is 0℃-45℃. Therefore, the high temperature is the upper working temperature limit of the POE switch +10℃ (i.e. 55℃), and the low temperature is the lower working temperature limit of the POE switch -10℃ (i.e. -10℃); the operating voltage range of the POE switch is 100-240V, therefore, the low voltage is the lower working voltage limit of the POE switch -10% (i.e. 90V), and the high voltage is the upper working voltage limit of the POE switch +10% (i.e. 264V).

[0060] Specifically, a POE switch is placed in a temperature and humidity control box. According to the temperature and humidity control instructions of the controller, the temperature and humidity control box is automatically controlled to achieve a high temperature of +10°C as the upper limit of the working temperature and a low temperature of -10°C as the lower limit of the working temperature; according to the voltage control instructions of the controller, the power supply equipment is automatically controlled to achieve a low voltage of -10% of the lower limit of the working voltage of the POE switch and a high voltage of +10% of the upper limit of the working voltage of the POE switch; an implementation method of the configuration instructions, such as Figure 2 As shown, the VLAN setting method is used to directly connect the POE switch interface up and down through the network cable, that is, use a 100-meter network cable to connect the interface 1 and interface 2 of the POE switch up and down, and the interface 3 and interface 4 up and down, and so on. Configure interface 2 and interface 3 as VLAN2, interface 4 and interface 5 as VLAN3, interface 6 and interface 7 as VLAN4, and so on; the first interface 1 and the last interface 10 are respectively connected to the sending port and the receiving port of the running flow meter; another implementation method of the configuration instruction, such as Figure 3 As shown, the VLAN setting method is used to directly connect the POE switch interface diagonally through a 100-meter network cable. For example, use a 100-meter network cable to diagonally connect interface 2 and interface 3 of the POE switch, and diagonally connect interface 4 and interface 5, and so on; configure interface 1 and interface 2 as VLAN2, interface 3 and interface 4 as VLAN3, interface 5 and interface 6 as VLAN4, and so on; the first interface 1 and the last interface 10 are respectively connected to the sending port and receiving port of the flow meter, and according to the parameter control instructions of the controller, the flow meter's message length, type and other parameters are automatically controlled, the second layer flow is played without speed limit, and the flow meter is controlled to send packets to realize serial flow. The interfaces of the POE switch are connected up and down or diagonally, and a flow loop is obtained. Press Figure 2 Connect 1-28 interfaces up and down and configure as shown in Table 1. Figure 3 The oblique connection mode is used to connect interfaces 1-28 obliquely and configure them as shown in Table 2; among them, ports 1 and 24 are connected to the Test Center Gigabit port, and ports 25 and 28 are connected to the 10 Gigabit port of the flow meter. The controller controls the flow meter to set parameters such as fixed 64 bytes and type UDP.

[0067] Step 2: Control the temperature of the temperature and humidity control box to the lower limit operating temperature of the POE switch -10°C.

[0072] Step 7, configure the POE switch for no-load serial oblique connection, that is, use a 100-meter network cable to connect the interfaces of the POE switch obliquely, interface 2 and interface 3 obliquely, interface 4 and interface 5 obliquely, and so on; configure interface 1 and interface 2 as VLAN2, interface 3 and interface 4 as VLAN3, interface 5 and interface 6 as VLAN4, and so on; the first interface 1 and the last interface 10 are respectively connected to the sending port and receiving port of the flow meter, and the controller automatically controls the flow meter to set the message length to random bytes, the type to UDP and other parameters, and repeat steps 2-6.

[0073] In this application, when the POE switch is tested under dual temperature and dual pressure, the temperature control of the low temperature is as follows: Fig.11 As shown, the low temperature is -10℃, and the test time is 24h; in the low temperature environment, 64 bytes are used for running flow test when the serial up and down are connected without load as shown in Table 3, and random bytes are used for running flow test when the serial bevel is connected without load in the low temperature environment as shown in Table 4.

[0078] Under dual temperature and dual pressure, when the POE switch is tested automatically with no-load serial flow, the high temperature control is as follows: Fig.12 As shown, the high temperature is 55°C and the test time is 24h. Similar to the low temperature test, 64 bytes are used for flow testing when the serial connection is unloaded in the high temperature environment, and random bytes are used for flow testing when the serial connection is unloaded in the low temperature environment. According to the test results, the frame loss rate, loss rate and standard are all 0, the test results are all passed, and reliable automated testing is also achieved.

According to the temperature and humidity control instructions of the controller, the temperature and humidity control box is automatically controlled to achieve temperature cycling, that is, the high temperature (+55°C) and the low temperature (-10°C) work for a period of time and the absolute value of the temperature change slope is 1 when the temperature changes; the VLAN setting method is used to realize the load parallel setting between the POE switch and the flow meter, that is, the upper interface and the lower interface of the POE switch are connected to the sending port and the receiving port of the flow meter respectively, and the upper interface of the POE switch is connected in series with the sending port of the flow meter. The load is connected in series between the load, the lower interface of the POE switch and the receiving port of the flow meter; more specifically, the interface 1 and interface 2 of the POE switch are connected to the flow meter through a 100-meter network cable + PD load to form a flow loop; interface 3 and interface 4 are connected to the flow meter through a 100-meter network cable + PD load to form another flow loop; and so on, to form multiple flow loops, the POE switch needs to supply power to the load (PD), configure interface 1 and interface 2 as VLAN2, interface 3 and interface 4 as VLAN3, interface 5 and interface 6 as VLAN4, and so on. The controller automatically controls the flow meter to run in parallel, that is, each flow loop runs at the same time. The automated main control PC controls the flow meter to set parameters such as message length and type, and plays the second layer flow without speed limit; based on the parameter setting, the flow meter is automatically controlled to implement single-machine serial flow.

[0114] The automated testing system of the POE switch of the present application has the following automated testing process for the POE switch under load parallel flow model under temperature cycling:

[0115] Step 100, load parallel setting.

[0116] Specifically, interface 1 and interface 2 of the POE switch are connected to the flow meter through a 100-meter network cable + PD load to form a flow loop; interface 3 and interface 4 are connected to the flow meter through a 100-meter network cable + PD load to form another flow loop; and so on, multiple flow loops are formed, and interface 1 and interface 2 are configured as VLAN2, interface 3 and interface 4 are configured as VLAN3, interface 5 and interface 6 are configured as VLAN4, and so on.

[0117] Step 200: The controller controls the temperature and humidity control box to make the working environment of the POE switch a temperature cycle.

[0118] In the example of this application, the temperature cycle is shown in 9; Th represents high temperature, and TI represents low temperature; the cycle works for a period of time at high temperature (+55°C) and low temperature (-10°C), and the absolute value of the temperature change slope is 1 when the temperature changes.

[0119] Step 300, based on the settings of the main controller on the parameters such as the length and type of the flow meter message, the flow meter is automatically controlled to run in parallel (each flow loop runs at the same time).

[0120] The POE switch of the present application supplies power to the PD load (with load + 100-meter network cable), connects the network interfaces of a switch in parallel in pairs and connects each to the flow meter, implements the switch port pair-by-pair running to fully detect the performance of the POE switch, and uses the flow meter to perform an automated test method for long-term stable flow, that is, to achieve automated testing of the POE switch with load and parallel flow model under a reliability climate environment (temperature cycle). In this embodiment, according to Fig. 9 The temperature curve shown in the figure was used for flow testing. According to the test results, the frame loss rate, loss rate and standard were all 0, the test results passed, and reliable automated testing was achieved.

[0121] In an embodiment of the present application, when the power supply voltage of the automated testing system is dual-voltage, the temperature in the temperature and humidity control box is dual-temperature, the test condition is no-load serial, and there is a POE switch, a no-load serial power on / off test is performed on the POE switch under dual-temperature and dual-voltage; wherein, the dual-voltage includes the upper limit of the working voltage of the POE switch and the lower limit of the working voltage of the POE switch; the dual temperature includes the upper limit temperature of the working of the POE switch and the lower limit temperature of the working of the POE switch; the serial adopts the VLAN setting method, and the first interface and the last interface of the POE switch are respectively connected to the sending port and the receiving port of the flow meter, and all the interfaces of the POE switch are connected up and down.

[0122] Specifically, Fig.10 As shown, a POE switch is placed in a temperature and humidity control box, and the automatic control box realizes dual temperature and dual pressure: the POE switch is in a constant climate environment of high temperature (upper limit temperature +10℃) and low temperature (lower limit temperature -10℃), under high pressure (upper limit voltage +10%) and low pressure (lower limit voltage -10%). When serially connected without load, the POE switch interface is directly connected up and down through the network cable by using the VLAN setting method. Specifically, the interface of the POE switch is connected up and down using a 100-meter network cable, interface 1 and interface 2 are connected up and down, interface 3 and interface 4 are connected up and down, and so on. Interface 2 and interface 3 are configured as VLAN2, interface 4 and interface 5 are VLAN3, interface 6 and interface 7 are VLAN4, and so on; the first interface 1 and the last interface 10 are respectively connected to the sending port and the receiving port of the flow meter; the first interface and the last interface are respectively connected to the flow meter, and the first interface and the last interface are used to check the flow performance after startup.

[0123] In some embodiments, a power supply device is used to power on and off the POE switch to perform a power on / off test, including a power on / off Ton test and a power on / off Toff test; the power on / off Ton test is used to detect the startup status of the functional modules of the POE switch after a sudden power outage and restart before completing normal startup; the power on / off Toff test is used to detect the startup status of the functional modules of the POE switch after a power outage and a quick power on.

[0124] Among them, the Ton test of power on and off is to detect the impact of power off after the POE switch is powered on normally but before the startup is completed, and then the power is turned on again on the startup of the functional modules of the POE switch. After the power is turned on, the POE switch is started up, and the POE switch interface check and flow check are implemented; Ton refers to the time interval between the power off of the POE switch after the POE switch is powered on normally but before the startup is completed;

[0125] Among them, the power on / off Toff test is to detect the impact of powering on the functional modules of the POE switch shortly after the switch is normally powered off. After power on, the POE switch is started, and the POE switch interface check and flow check are implemented; Toff refers to the time interval between the POE switch being powered off and being powered on again.

[0126] This application uses an automated tool to set a large number of test times or test durations to cyclically test the startup stability and reliability of the POE switch.

[0127] The automated testing system of the POE switch of the present application has the following automated testing process for the POE switch on and off under dual temperature and dual pressure conditions:

[0128] Step 1), connect the interfaces of the POE switch up and down, and configure the interfaces of the POE switch using VLAN settings.

[0129] Use a 100-meter network cable to connect the interfaces of the POE switch up and down, interface 1 and interface 2 up and down, interface 3 and interface 4 up and down, and so on, configure interface 2 and interface 3 as VLAN2, interface 4 and interface 5 as VLAN3, interface 6 and interface 7 as VLAN4, and so on; the first interface 1 and the first interface 10 are respectively connected to the sending port and receiving port of the flow meter; among them, the first interface and the last interface are used for flow function inspection after startup.

[0130] Step 2), the controller automatically controls the temperature of the temperature and humidity control box to a high temperature environment (working upper limit temperature + 10°C).

[0131] Specifically, the controller automatically controls the power supply equipment to achieve high voltage power supply (working upper limit voltage + 10%).

[0132] Step 3), use the power supply equipment to power on and off the POE switch to perform a power on and off test.

[0133] Power on / off Ton test: EUT is powered on, and then powered off within the Ton time. Then it waits for the normal time (default 1 second, which can be set) to be powered on, and then waits for the Tboot time (Tboot indicates the total time required for the POE switch to start up from power on to completion). After that, the POE switch starts up normally, and the running flow checks the functional modules of the POE switch; the cycle test is completed according to the number of power on / off Ton tests set automatically.

[0134] Step 4), use the power supply equipment to power on and off the POE switch to perform a power on and off test.

[0135] Power on / off Toff test: after the POE switch starts normally, cut off the power, and then power on again within the Toff time. After the POE switch starts normally, run the flow to check the POE switch function module; complete the cycle test according to the number of power on / off Toff tests set automatically.

[0136] Step 5), automatically control the power supply equipment to achieve low voltage power supply (working lower limit voltage -10%), and repeat steps 3) and 4).

[0137] Step 6), automatically control the temperature box to achieve a low temperature environment (working lower limit temperature -10°C), automatically control the power supply equipment AC Source to achieve high voltage power supply (working upper limit voltage +10%), and repeat steps 3)-5).

[0138] The POE switch of the present application works under high voltage (working upper limit voltage +10%) and low voltage (working lower limit voltage -10%) conditions in a high temperature (working upper limit temperature +10°C) and low temperature (working lower limit temperature -10°C) climate environment, and uses a power supply device to perform power-on and power-off tests to detect the impact of the POE switch being powered on and then powered on again after power-off is triggered before the startup is completed, and the impact of the POE switch being powered on again in a very short time after the POE switch is powered off on the startup of the functional modules of the POE switch. By increasing the number and duration of tests, an automated test of the startup stability of the POE switch is performed, that is, automated testing of the POE switch power-on and power-off model is achieved under a reliable climate environment (dual temperature and dual pressure); in this embodiment, according to the power-on and power-off test results under a high temperature and high pressure environment, the switch test results under a high temperature and low pressure environment, the test results under a low temperature and high pressure environment, and the test results under a low temperature and low pressure environment, the port rate, flow detection, network performance and test results are all passed, and reliable automated testing is also achieved.

[0139] The present application automatically controls a temperature and humidity control box, a flow meter, and a power supply device, so that different test conditions are determined according to the power supply voltage, flow parameters, temperature and / or humidity, and test conditions to match different test networks; the POE switch is subjected to long-term flow tests such as no-load, loaded, serial, parallel, and multi-machine tests, as well as automatic power-on and power-off tests under different climatic environments; it supports a variety of test frame lengths (fixed frame lengths such as 64 bytes, 1518 bytes, and random frame lengths), a variety of test models (VLAN mode, port mutual message mode), a variety of product interfaces (electrical port, optical port), and a variety of network port rates (10M / 100M / 1000M / 2.5G / 10G); the automatic main control PC controls the temperature adjustment of the incubator and the power supply voltage adjustment of the power supply device, controls the flow meter to adjust the flow parameters and record the throughput data and packet loss rate, configures the POE switch, and records the serial port data of the POE switch.
