Through this monitoring, it can be ensured that the environmental parameters in the cold channel remain within the appropriate range, thereby ensuring the normal operation of the equipment in the computer room.

[0003] At present, the commonly used cold channel monitoring method is to place a monitoring and acquisition host in the cold channel, and the monitoring and acquisition host has multiple host interfaces.

[0035] Reference Figure 1-Figure 3 An embodiment of the present application provides a computer room cold channel environment control device, including a cold channel control module and an installation module.

[0037] In the embodiment of the present application, the control unit is connected to the sensor interface unit, the detection interface unit, the interface of the sunroof electromagnet, the display screen, the button, the communication interface and the RGB light strip interface. The control unit is used to connect to the channel monitoring host, upload the data and status of the sensor interface unit, the detection interface unit, the sunroof electromagnet, etc., for the channel monitoring host to monitor, and the channel monitoring host can also control the control unit. Optionally, the control unit is a single-chip microcomputer, model STM32G030C8T6.

[0038] In one embodiment, the sensor interface unit includes a temperature and humidity sensor interface, an air pressure sensor interface, and a smoke alarm interface. Therefore, the sensing elements connected to the sensor interface unit may include a temperature and humidity sensor, an air pressure sensor, and a smoke alarm. Other embodiments may include one or more of a temperature and humidity sensor interface, an air pressure sensor interface, and a smoke alarm interface.

[0039] In one embodiment, the detection interface unit includes an infrared detector interface and a sunroof door magnet interface (sunroof status door magnet monitoring interface). The infrared detector interface is connected to the infrared detector and can be used to detect objects. The sunroof door magnet interface is connected to the sunroof door magnet and can detect whether the sunroof is illegally opened or moved. Therefore, the detection element can include a sunroof door magnet and an infrared detector.

[0040] Among them, when an alarm is triggered in abnormal situations such as fire fighting, the management and control unit can control the skylight electromagnet to open the skylight, allowing fire fighting gas and the like to enter the passage to extinguish the fire. In order to meet the fire fighting requirements of opening the skylight when the power is off, the skylight electromagnet is usually used for adsorption and is in a closed state. When an alarm is triggered, the power is cut off, and then the skylight will drop and open.

[0041] In the embodiment of the present application, the installation module includes at least one installation part, and the installation part has an installation position, and the installation position is used to install the cold channel control module, the sensor element connected to the sensor interface unit, the detection element connected to the detection interface unit, and the skylight electromagnet.

For example, the sensor element includes a temperature and humidity sensor, an air pressure sensor, and a smoke alarm, then it includes mounting holes corresponding to the temperature and humidity sensor, the air pressure sensor, and the smoke alarm respectively; the detection element may include a skylight door magnet and an infrared detector, then it includes mounting holes corresponding to the skylight door magnet and the infrared detector respectively; and it also includes mounting holes corresponding to the cold channel control module and the skylight electromagnet respectively. In the embodiment of the present application, the mounting hole is also provided with a snap-fit ​​structure, so that the element installed in the mounting hole can be snap-fitted and fixed, which is convenient for fixing and subsequent disassembly and maintenance.

[0043] It should be noted that the number of skylights, sensor elements, detection elements, skylight electromagnets, etc. can be set based on actual conditions, so the number of cold channel control modules and mounting parts can be determined based on actual conditions, and one cold channel control module corresponds to one mounting part.

[0044] Optionally, the communication interface is an RS485 interface, and the number of communication interfaces can also be based on actual settings. The RS485 interface is used to connect to the channel monitoring host and / or connect to other cold channel control modules. In some embodiments, if only one cold channel control module is involved, the communication between the cold channel control module and the channel monitoring host can be achieved through an RS485 interface, or when multiple cold channel control modules are involved, the communication between the cold channel control module and the channel monitoring host is achieved through their respective RS485 interfaces. In an embodiment of the present application, each cold channel control module can be provided with two RS485 interfaces (recorded as a first RS485 interface and a second RS485 interface), for example Figure 4 As shown, there are two cold channel control modules, namely cold channel control module 1 and cold channel control module 2. The power cord of the channel monitoring host is connected to the power interface of the cold channel control module 1, and the power interface of the cold channel control module 1 is connected to the power interface of the cold channel control module 2 to realize power supply; the first RS485 interface of the cold channel control module 1 is connected to the channel monitoring host for communication, and the second RS485 interface of the cold channel control module 1 is connected to the first RS485 interface of the cold channel control module 2, and the second RS485 interface of the cold channel control module 2 can be connected to the cold channel control module 3 (not shown). Similarly, when multiple cold channel control modules are involved, they only need to be connected in series to realize communication, which can reduce the connection cables of the channel monitoring host and the occupancy of the port of the channel monitoring host, save the RS485 interface resources of the channel monitoring host, and facilitate the transmission of the collected data to other monitoring devices through the monitoring host.

[0045] like Figure 5 As shown, optionally, the cold channel control module also includes a display screen interface circuit, including a resistor RT1 and a first resistor R1, the resistor RT1 and the first resistor R1 are connected to a display screen JLCD, model LCD1602, and the voltage output by the power interface is used to power the display screen interface circuit.

The temperature and humidity sensor interface JTH is connected to resistors R7 and R8; the temperature and humidity sensor interface JTH is connected to resistors R13 and R14.

[0049] like Fig. 9 As shown, it is a circuit diagram of the interface CON2 of the sunroof electromagnet, which has a resistor R15, a transistor T1, a diode D1, and a relay K1. The control unit controls the state of the relay K1 by controlling the level of the transistor T1 to achieve control of the sunroof electromagnet.

[0050] like Fig.10 As shown, it is a circuit diagram of the RGB light strip interface JRBG, which has the RGB light strip interface JRBG connecting resistors R16, R17, R18, and field effect transistors QR1, QB1, and QG1.

[0052] The embodiment of the present application saves manpower and consumables on-site by providing a cold channel control module and mounting parts. Even if multiple cold channel control modules are involved, the channel monitoring host only needs one set of power lines and one set of communication lines connected in series to achieve power supply and communication, which is conducive to lowering the entry threshold for installation and maintenance personnel. There are various special interfaces such as sensor elements and detection elements on the cold channel control module. The access status and actual working status of the sensor elements and detection elements can be seen on the display screen, which is convenient for on-site personnel to assist in installation and troubleshooting. Through key input, the alarm threshold and control logic can be set, such as setting the upper limit of the temperature threshold to 30 degrees, directly opening the movable skylight when the alarm is triggered, and the RGB light strip turning red when the alarm is triggered, etc., and installation, use and troubleshooting are extremely convenient and easy.

[0053] In addition, the cold channel control modules and mounting parts can achieve product standardization and can be pre-installed in the factory. The distance between each sensor element and detection element and the interface is standard, and the length of the connecting wires and connectors are also standard. The length of the connecting wires can also be calculated and produced in advance. The factory can pre-install all sensor elements and detection elements on the mounting parts. At the project site, you only need to connect the connecting wires between the cold channel control modules to complete the installation.

[0054] The embodiment of the present application also provides a control system, including a channel monitoring host and the above-mentioned computer room cold channel environment control device.
