Description
Technical Field
The invention relates to the technical field of heating ventilation air conditioners, in particular to a method for improving data acquisition quality of air conditioner time type metering equipment.
Background
The metering charging mode of the air conditioner is generally divided into two modes: energy type and time type. Energy-based metering devices are typically rarely used by small-scale owners because of air conditioning design, higher cost, and limited installation conditions. Therefore, the time-based metering is suitable for office buildings, small shops, business apartments, residential districts and other business conditions.
The main advantages of time-based metering are: the manufacturing cost is low, and the construction cost is low; the electronic system has small influence of external interference and long service life; the air conditioner water system is not related, and the installation, debugging and maintenance are very convenient; the operation of the air conditioning unit and the normal use of other users are not influenced; the fan coil at the tail end is used as a measuring object, the applicability is wide, and the influence of the change of the house type structure and the room interval is avoided. Especially, when the time type metering equipment adopting wireless communication is adopted, only the power is needed to be taken at the fan coil, the equipment is installed, the data is transmitted back to the metering system in a wireless mode, and the convenience is brought, and the laying of power supply and communication cables is omitted.
However, two situations are often encountered when using wireless metering devices: firstly, the owner closes the main electric brake of the house, and the metering equipment cannot work after being powered off because the metering equipment takes power from the fan coil pipe in the owner; and secondly, due to the fault of the wireless router, although the metering equipment can work when power is supplied, the metering data cannot be transmitted back to the platform software of the metering system.
In the first case, the power of the owner is cut off, the fan coil cannot work, so that the energy cost for air conditioning cannot be generated, and the owner can easily explain that the stop code of the metering equipment is not changed during the power-off period, and only intermediate data is lost.
The second situation will bring a great obstacle to the operator because although the end code of the metering device cannot be collected, if the user uses the air conditioner, the end code of the metering device will increase all the time, and as a result, the end code displayed by the upper computer will not change within a period of time, and a sudden rising end code will appear after the wireless route is normal. On the one hand the owner may be confused about the data and on the other hand it is not possible to implement a step charge for the time period.

step 1: when the communication is normal, the data is directly transmitted back to the metering system platform for display and storage;
step 2: once the singlechip detects that the communication is not up, starting to store the metering stop code with the timestamp in a timing storage area of a singlechip memory according to a specified time interval;
and step 3: and after the communication is recovered, uploading one stored stop code to the metering system platform according to the timestamp.
Further, the logic of the real-time storage of the stop code is to update the stop code of the real-time storage area every 1-5 seconds on the premise that the stop code is changed.
Further, the logic of storing the stop codes at regular time is that the stop codes in the real-time storage area are copied to the regular storage area every 10-30 minutes, and meanwhile, a time stamp is added, so that the stop codes are still stored at regular time even if the fan coil is not used and the stop codes are not changed; storing data table contents includes: time stamp, low-grade stop code, middle-grade stop code, high-grade stop code and zone bit.

step 1: starting metering;
step 2: recording to a real-time storage area in real time;
