Problems solved by technology

During the operation of the system, the air conditioner was cut off due to power failure, and the centralized control center was far away, and the maintenance personnel failed to restore the operation of the air conditioner in time, causing the temperature in the computer room to be too high
[0003] In the absence of monitoring equipment, the staff cannot know the situation of the computer room in the station from a distance. Usually, after some electrical equipment fails, the maintenance personnel arrive at the scene and find that the air conditioner has stopped working. The failure of the equipment is caused by the failure of the air conditioner to work normally
If this situation is to be avoided, it is usually necessary to send some manpower to inspect the operation of the air conditioners at each station, but this is undoubtedly a great waste of manpower, material resources, and financial resources, and even this may not be timely. avoid abnormal situations

Embodiment Construction

[0010] The present invention uses the digitized temperature sensor DS1820 of Dallas Semiconductor Company to collect the temperature. DS18B20 can be programmed to set a resolution of 9~12 bits, with an accuracy of ±0.5°C. Optional smaller package, wider voltage range. The resolution setting and the alarm temperature set by the user are stored in EEPROM, and they will still be saved after power off.

[0011] The digital thermometer reflects the temperature value of the device DS1820 in the form of 9 digits. The DS1820 sends or receives information through a single-wire interface, so only one connection wire (plus ground) is required between the central microprocessor and the DS1820. Power for reading and writing and temperature conversion can be obtained from the data line itself, no external power supply is required. Because each DS1820 has a unique chip serial number, multiple DS1820s can be connected to a single-wire bus at the same time, allowing temperature sensors to b...

Abstract

The invention discloses a remote monitoring system for an air conditioner in a substation machine room, and relates to a monitoring system. The system comprises a temperature sensor, a digital thermometer, an infrared emission sensor and related software, wherein the temperature sensor has warning temperatures of a resolution setting and a user setting, stored in an EEPROM (Electrically Erasable Programmable Read-Only Memory); the digital thermometer is used for reflecting the temperature value of a device in a nine-digit quantity mode and sending/receiving information via a single-wire interface and is connected with a central microprocessor; the infrared emission sensor and an infrared receiving sensor are used in a matching way to form an infrared remote control system, an infrared remote control signal is a series of binary pulse codes and is firstly modulated on a specified carrier frequency, and the on/off of the air conditioner can be controlled by the software when the infrared remote control signal is matched with the current air conditioner. The remote monitoring system is suitable for an unmanned substation, monitoring of the operation of an air conditioner device without a special channel, detection on the temperature and the humidity of an environment and remote switching of the air conditioner device.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a remote monitoring system for an air conditioner in a computer room. Background technique [0002] The computer room of the centralized control center of the power supply company is set up in a 220kV substation. The air conditioners in the computer room are 4 sets of KFRd-72LW / Z5 and 4 sets of KFRd33CW E3-S5. The computer room of the centralized control center is the operating place of the core equipment of the centralized control center monitoring system. The temperature and humidity conditions of its operating environment are the key to ensure the stable operation of the system and prolong the service life of the equipment. During the operation of the system, the air conditioner was cut off due to power failure, and the centralized control center was far away, and the maintenance personnel failed to resume the operation of the air conditioner in time, causing the temperature in the compu...
