Description

Technical Field

[0001] The present application relates to the technical field of temperature control in computer rooms, and in particular to a ventilation, filtration and energy-saving system based on an ARM architecture. Background Art

[0002] The highway computer room is an important part of the highway toll collection system. It is mainly located in the highway toll station to provide a stable and safe working environment for the toll collection system. The computer room is equipped with advanced servers, network equipment and security systems, which are responsible for real-time processing and storage of traffic flow data, toll amount and other information passing through the toll station to ensure the accuracy, integrity and security of the data. Therefore, a large amount of heat will be generated, so each computer room will be equipped with a cooling system. The general computer room cooling system is implemented by traditional air conditioning, that is, an internal unit is set in the computer room, and an external unit is set outside the computer room, and the temperature in the computer room is maintained by air conditioning.

[0003] However, since the indoor unit in the computer room is set to the same temperature all year round, the cooling work will be performed in the same way regardless of the status of the equipment in the computer room. The computer room must adopt a 24-hour uninterrupted operation of the air conditioner to maintain the room temperature to meet the standard and ensure the operation of the equipment. As a result, the refrigeration system consumes a lot of energy, resulting in unnecessary energy waste.

[0004] Therefore, how to flexibly select the temperature control method for the computer room according to the temperature inside and outside the computer room is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] In order to solve the above technical problems, this application proposes the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a ventilation, filtration and energy-saving system based on an ARM architecture, comprising: an ARM controller arranged in a computer room, the ARM controller being electrically connected to a temperature monitoring device and an air ventilation device, the ARM controller monitoring the temperature inside and outside the computer room through the temperature monitoring device, and controlling the air ventilation device to perform ventilation and lower the temperature in the computer room according to preset judgment conditions.

[0007] In a possible implementation, the temperature monitoring device includes a main control chip, a first temperature sensor and a second temperature sensor electrically connected to the main control chip, the first temperature sensor is arranged in the machine room, and the second temperature sensor is arranged outside the machine room; there are multiple second temperature sensors, and the multiple second temperature sensors are arranged at different positions outside the machine room. The first temperature sensor is used to realize temperature collection in the machine room, and the second temperature sensor is used to realize temperature collection outside the machine room. The temperature information collected by the temperature sensor is directly sent to the main control chip. The second temperature sensors are arranged at different directions of the machine room to realize dynamic monitoring of the outdoor temperature.

[0008] In a possible implementation, a pull-up resistor is provided between the first temperature sensor and the main control chip, and two ends of the pull-up resistor are electrically connected to a data output port of the first temperature sensor and a data receiving port of the main control chip, respectively. The measurement current is adjusted by the pull-up resistor to ensure that the collected indoor temperature data is accurate.

[0009] In a possible implementation, the main control chip is also connected to a display and a buzzer, respectively. The display is used to display temperature data and system status, and the buzzer is used to send an alarm. Once the temperature in the computer room exceeds a preset threshold, a buzzer alarm is immediately triggered to promptly remind the user to take corresponding measures. The display displays indoor and outdoor temperature information and system operation status in real time, providing users with an intuitive system monitoring interface.

[0010] In a possible implementation, the air ventilation device includes a fan arranged outside the machine room, an air duct embedded in the wall of the machine room, and an air outlet of the air duct is arranged in the machine room.

[0011] In a possible implementation, a first filtering device is provided at the air inlet of the fan, and a second filtering device is provided in the air duct. The first filtering device performs a primary filter on the cold air entering the fan, and the second device performs a secondary filter on the air blown into the air duct by the fan.

[0012] In one possible implementation, the air ventilation device is controlled to perform ventilation to lower the temperature in the computer room according to preset judgment conditions, including determining whether the outdoor temperature is lower than the indoor temperature of the computer room, and whether the outdoor temperature meets the set temperature for the equipment in the computer room. If so, the air ventilation device is controlled to operate.

[0013] In a possible implementation, a cloud system is constructed to communicate data with the ARM controller, so as to realize online temperature monitoring and historical data recording in the cloud, and monitor and record the temperature changes of the computer room through two interactive pages, namely, the PC and the APP.

[0014] In one possible implementation, the cloud system includes an API interface layer, a basic service layer, a data layer and a cloud database. The API interface layer implements the API KEY and load balancing of the cloud system. The basic service layer implements real-time temperature viewing, real-time humidity viewing, temperature historical data query, humidity historical data query, message push service and log recording; the data layer implements data caching, read and write database, cache expiration control, file reading and writing and data synchronization, and the transport library includes an SQL database and a file system.

[0015] In an embodiment of the present application, the temperature inside and outside the computer room is monitored by a temperature monitoring and control device, and the acquired temperature information is sent to an ARM controller. After the ARM controller compares the received temperature information inside and outside the computer room, if temperature control is required, a control instruction is sent to the air ventilation device to achieve temperature control of the computer room, and the computer room is cooled by cold air from the outside, thereby reducing energy waste.
