[0023] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0024] See Figures 1-5 As shown, it is an intelligent dynamic loop host device, which includes a housing 6 and a switching power supply 2 and a PCB board 1 installed in the housing 6.

[0025] On the PCB board 1, there are a first power input terminal 11, a second power input terminal 12, a dual-power switching module 3, a protection module 4, a communication module 5, two built-in temperature and humidity interfaces 13, an RS485 interface 14, an RS232 interface 15, a DI interface 16, a DO interface 17, a water leakage detection interface 18, a network interface 19, a power output interface 10, and an analog output interface 101; among them, the switching power supply 2 is connected to the second power input terminal 12 and can output a main power supply 102; the switching power supply 2 is connected to the first power input terminal 11 and can output a backup power supply 103; the dual-power switching module 3 is connected to the switching power supply 2 to control the output of the main power supply or the backup power supply; one path of the output main power supply or backup power supply is connected to the built-in temperature and humidity interface 13 and the communication module 5 for power supply; the other path of the output main power supply or backup power supply is connected to the protection module 4, and then the protection module 4 is connected to the RS485 interface 14, the RS232 interface 15, the DI interface 16, the DO interface 17, the water leakage detection interface 18, the power output interface 10, and the analog output interface 101 for power supply. The RS485 interface 14, the RS232 interface 15, the DI interface 16, the DO interface 17, the water leakage detection interface 18, the power output interface 10, and the analog output interface 101 are all exposed on the outer surface of the housing 6 and are used to connect to external devices / devices.

[0026] In this embodiment, the first power input terminal 11 is a DC input terminal, and the second power input terminal 12 is an AC input terminal.

[0027] The utility model has various different types of interfaces, such as RS485 interface 14, RS232 interface 15, DI interface 16, DO interface 17, water leakage detection interface 18, power output interface 10, and analog output interface 101, which are used to connect with various devices or apparatuses, and are extremely convenient to use. And the utility model adopts two power supply modes of the first power input end 11 and the second power input end 12, and outputs the main power supply 102 and the standby power supply through the switching power supply 2, and then the dual-power switching module 3 is connected to the switching power supply 2 to control the output of the main power supply or the standby power supply. When an abnormal power failure or other abnormal states occur at the second power input end 12, the dual-power switching module 3 switches to the standby power supply for power supply, thereby ensuring that the intelligent dynamic environment monitoring host device of the utility model can work normally, making the intelligent dynamic environment monitoring host device of the utility model work more stably and reliably, and not affecting the monitoring of the entire computer room working environment. Furthermore, the output main power supply or standby power supply is connected to the protection module 4 on the other path, and then the protection module 4 is connected to the RS485 interface 14, RS232 interface 15, DI interface 16, DO interface 17, water leakage detection interface 18, power output interface 10, and analog output interface 101 for power supply. When short circuit or overcurrent phenomena occur to the devices connected to the RS485 interface 14, RS232 interface 15, DI interface 16, DO interface 17, water leakage detection interface 18, power output interface 10, and analog output interface 101, the protection module 4 will cut off the subsequent current output to prevent other subsequent devices from being burned out. Since the output main power supply or standby power supply is connected to the built-in temperature and humidity interface 13 and the communication module 5 for power supply on one path, and it does not need to pass through the protection module 4, that is, the system power supply is before the protection module 4, so even if short circuit and overcurrent abnormalities occur in the subsequent circuit of the protection module 4, it does not affect the normal operation of the utility model. When the abnormal phenomena are removed, the subsequent circuit continues to supply power, ensuring the stability and safety of the system. That is to say, the utility model separates the external power supply and the internal power supply through the protection module. Even if problems such as short circuit and overload occur to the externally connected devices, the utility model can still work stably.

[0028] The subsequent circuit continues to supply power means that the RS485 interface 14, RS232 interface 15, DI interface 16, DO interface 17, water leakage detection interface 18, power output interface 10, and analog output interface 101 can supply power to the devices they are connected to.

[0029] In addition, due to the large number of interface types of the utility model, users can independently select and purchase corresponding function modules to dock with the utility model according to personalized needs. Once installed, the utility model will periodically establish communication connections with the connected devices and perform data collection work. These collected data will then be used to realize data exchange with the external system through the built-in communication module.

[0030] The communication module 5 includes a wireless communication module and / or a wired communication module, and is communicatively connected to an external system through the wireless communication module or the wired communication module to exchange data with the external system; the external system obtains various data recorded by the current device through a query method. When it is detected that the set monitoring parameters exceed or are lower than the preset threshold range, the external system will automatically push notifications through the web page, or send reminders in the form of text messages or phone calls to ensure that the user can timely master the status of each device and take corresponding measures; specifically, for the convenience of real-time monitoring and management of data, the external system (also called the external platform) provides a communication protocol, and can easily obtain various data recorded by the current device through a query method. More intelligently, when it is detected that the set monitoring parameters exceed or are lower than the preset threshold range, the external system will automatically push notifications through the web page, or send reminders in various forms such as text messages and phone calls to ensure that the user can timely master the device status and take corresponding measures.

[0031] The wireless communication module includes any one of zigbee, LORA, wifi, Bluetooth, 2G / 4G / 5G / 6G communication modules, and the wired communication module includes any one of RS485, RS422, LINE, CAN, power bus modules.

[0032] Among them, two built-in temperature and humidity interfaces 13 are placed inside the housing. The front and rear ends of the housing 6 are respectively provided with a first temperature and humidity sensor 61 and a second temperature and humidity sensor 62 that are respectively connected to the two built-in temperature and humidity interfaces 13 one by one. After the housing is installed in the cabinet, the first temperature and humidity sensor 61 is placed in the cold aisle of the cabinet, and the second temperature and humidity sensor 62 is placed in the hot aisle of the cabinet to directly and real-time monitor the temperature in the cold aisle and the aisle of the cabinet. That is to say, when the present utility model is specifically used, after it is installed in the U position of the cabinet, the first temperature and humidity sensor 61 is placed in the cold aisle of the cabinet, and the second temperature and humidity sensor 62 is placed in the hot aisle of the cabinet to directly and real-time monitor the temperature in the cold aisle and the aisle of the cabinet. By real-time monitoring of the temperature, problems can be timely discovered and the heat dissipation strategy can be adjusted to ensure the normal operation of other devices assembled in the cabinet.

[0033] The switching power supply 2 has both AC to DC function and DC to DC function. It is a relatively mature product and will not be elaborated in detail here.

[0034] The dual - path power supply switching module 3 includes voltage - dividing resistors R5 and R7, voltage - dividing resistors R11 and R12, MOS transistors Q1 and Q2, MOS transistors Q4 and Q5, MOS transistors Q6 and Q7, operational amplifier U1, first inverter U2, and second inverter U3; the voltage - dividing resistors R5 and R7 are sequentially connected to the main power supply 102; the MOS transistors Q1 and Q2 are sequentially connected to the main power supply 102; the voltage - dividing resistors R12 and R12 are sequentially connected to the backup power supply 103; the MOS transistors Q6 and Q7 are sequentially connected to the backup power supply 103; both the voltage - dividing resistors R7 and R11 are grounded, and the connection lines between the voltage - dividing resistors R5 and R7 and between the voltage - dividing resistors R11 and R12 are respectively connected to the inverting terminal and non - inverting terminal of the operational amplifier U1; the output terminal of the operational amplifier U1 is connected to the input terminal of the first inverter U2, the output terminal of this first inverter U2 is respectively connected to the input terminals of the MOS transistor Q4 and the second inverter U3, the output terminal of this second inverter U3 is connected to the MOS transistor Q5, this MOS transistor Q4 is connected to the MOS transistors Q1 and Q2 to control the on - off of the MOS transistors Q1 and Q2, this MOS transistor Q5 is connected to the MOS transistors Q6 and Q7 to control the on - off of the MOS transistors Q6 and Q7, and both the MOS transistors Q2 and Q7 are connected to the power output terminal 100. A Schottky diode D5 is also connected between the output terminal of the operational amplifier U1 and the input terminal of the first inverter U2. The D - pole of the MOS transistor Q1 is connected to the main power supply 102, the S - pole of the MOS transistor Q1 is connected to the S - pole of the MOS transistor Q2, the G - poles of both the MOS transistor Q1 and the MOS transistor Q2 are connected to the D - pole of the MOS transistor Q4, the G - pole of the MOS transistor Q4 is connected to the output terminal of the first inverter U2, the S - poles of both the MOS transistor Q4 and the MOS transistor Q5 are grounded, the G - pole of the MOS transistor Q5 is connected to the output terminal of the second inverter U3, the G - poles of both the MOS transistor Q6 and the MOS transistor Q7 are connected to the D - pole of the MOS transistor Q5, the S - pole of the MOS transistor Q6 is connected to the S - pole of the MOS transistor Q7, the D - pole of the MOS transistor Q6 is connected to the backup power supply 103, and the D - poles of both the MOS transistor Q2 and the MOS transistor Q7 are connected to the power output terminal 100.

[0035] Both the main power supply 102 and the backup power supply 103 are 12V. The main power supply 102 and the backup power supply 103 are connected to a first step - down voltage - regulating chip 104, the first step - down voltage - regulating chip 104 is connected to a second step - down voltage - regulating chip 105, the output terminal of the first step - down voltage - regulating chip 104 is connected to a +9V terminal 106, and the output terminal of the second step - down voltage - regulating chip 105 is connected to a +5V terminal 107.

[0036] The working principle of the dual - path power supply switching module 3 is as follows:

[0037] After the first power input terminal 11 and the second power input terminal 12 pass through the switching power supply 2, the main power supply 102 of 12V and the standby power supply 103 are obtained.

[0038] The 12V main power supply 102 is divided by the voltage dividing resistors R5 and R7, and the 12V standby power supply 103 is divided by the voltage dividing resistors R12 and R11, and R7 > R11. Therefore, under the condition of the same voltage U R7 >U R11 . U R7 and U R11 are respectively connected to the inverting terminal and the non-inverting terminal of the operational amplifier U1. The V+ terminal of the operational amplifier U1 is connected to the 9V power supply, and the V- terminal of the operational amplifier U1 is connected to the system ground. The output of the operational amplifier U1 is connected to the inverter U2. One output of the inverter U2 is connected to the MOS transistor Q4, and one output passes through the inverter U3 and is connected to the MOS transistor Q5.

[0039] Under normal circumstances, since U R7 >U R11 , the operational amplifier U1 outputs a low level, which is output to the gate of the MOS transistor Q4 through the inverter U2, and the MOS transistor Q4 conducts. The drain of the MOS transistor Q1 is connected to the 12V power supply. Ignoring the body diode voltage drop of the MOS transistor, the sources of the MOS transistors Q1 and Q2 are both 12V. Since the gates of the MOS transistors Q1 and Q2 are both 0V, V gs meets the turning-on condition, so the MOS transistors Q1 and Q2 conduct. The low level output by the operational amplifier U1 is output to the MOS transistor Q5 through U3, so the MOS transistor Q5 is turned off. The gate voltage of the MOS transistor Q5 is equal to the source voltage of the MOS transistors Q6 and Q7, and the MOS transistor Q7 is turned off, so the main power supply voltage is output.

[0040] When the main power supply is abnormally powered, the voltage U R7 <U R11 , the operational amplifier U1 outputs a high level, which outputs a high level after passing through the inverters U2 and U3, and the MOS transistor Q5 conducts. The drain of the MOS transistor Q6 is connected to the 12V power supply. Ignoring the body diode voltage drop of the MOS transistor, the sources of the MOS transistors Q6 and Q7 are both 12V after passing through the body diode. Since the gates of the MOS transistors Q1 and Q2 are both 0V, V gs meets the turning-on condition, so the MOS transistors Q6 and Q7 conduct. The high level output by the operational amplifier U1 is output to the MOS transistor Q4 through the inverter U2, so the MOS transistor Q4 is turned off. The gate voltage of the MOS transistor Q2 is equal to the source voltage of the MOS transistors Q1 and Q2, and the MOS transistors Q6 and Q7 are turned off, so the standby power supply voltage is output.

[0041] The protection module 4 is an overcurrent protection module, which includes a current limiting switch chip 41. The IN pin of the current limiting switch chip 41 is connected to the main power supply 102 and the backup power supply 103. The OUT pin of the current limiting switch chip 41 is connected to the RS485 interface 14, the RS232 interface 15, the DI interface 16, the DO interface 17, the water leakage detection interface 18, the power output interface 10, and the analog output interface 101. When short circuit or overcurrent occurs in the devices connected to the RS485 interface 14, the RS232 interface 15, the DI interface 16, the DO interface 17, the water leakage detection interface 18, the power output interface 10, and the analog output interface 101, the overcurrent protection module will cut off the subsequent current output to prevent other subsequent devices from being burned. Since one path of the output main power supply or backup power supply is connected to each module on the PCB board 1 such as the built-in temperature and humidity interface 13 and the communication module 5 to supply power to each module on the PCB board 1, and it does not need to pass through the overcurrent protection module, that is, the system power supply is before the overcurrent protection module. Therefore, even if short circuit and overcurrent anomalies occur in the subsequent circuit of the overcurrent protection module, it does not affect the normal operation of the present invention. When the abnormal phenomenon is removed, the subsequent circuit continues to supply power, ensuring the stability and safety of the system.

[0042] The RS485 interface 14 is connected to the UART to RS485 module 141 and then connected to the overcurrent protection module and the embedded system 7; the DI interface 16 is connected to the optocoupler isolator 161 and then connected to the overcurrent protection module and the embedded system 7; the DO interface 17 is connected to the relay 171 and then connected to the overcurrent protection module and the embedded system 7; the water leakage detection interface 18 is connected to the isolated DC-DC chip 181 and connected to the overcurrent protection module and the embedded system 7.

[0044] The embedded system 7 is also connected to an RTC module 73, and the RTC module 73 can provide an accurate clock in the network offline state.

[0045] One path of the output main power supply or backup power supply is also connected to the RTC module 73 and the disk interface 71 for power supply.

[0046] The present invention is equipped with an access control system, and the access control system can be used in combination with the analog output interface. The access control system can use the connected LED lights to indicate different states of the door.

[0047] In summary, the present utility model provides a dynamic environment host device that has multiple interfaces, is convenient for deployment, convenient for device docking, convenient for memory expansion, can operate for a long time, and can notify alarms through text messages, phone calls, etc. Moreover, the power supply system of the present utility model adopts dual-power supply. Even when one power supply fails, it can still continue to work stably relying on the other power supply. At the same time, the external power supply and the internal power supply are separated by a protection module. Even if problems such as short circuit and overload occur in the externally connected devices, the present utility model can still work stably.
