Detailed description of the invention
Embodiment 1.
Fig. 1 ~ Fig. 3 is the figure representing embodiment 1 of the present utility model.
Fig. 1 is the skeleton diagram of the formation of the service data storage device of the equipment represented in present embodiment 1.
In addition, in present embodiment 1, enumerate cooling and heating machine and carry out devices illustrated.This situation is also identical in following embodiment 2 with embodiment.
As shown in Figure 1, cooling and heating machine 1 is formed primarily of compressor 2, cross valve 3, condenser 4, expansion valve 5, evaporimeter 6, refrigerant piping 7 and sensor 8.Compressor 2 is connected by refrigerant piping 7 with cross valve 3.
Compressor 2 sucks cold-producing medium, and discharges after refrigerant compression to cross valve 3.Sensor 8 is arranged in the mode be connected with compressor 2, detects pressure and the temperature of the cold-producing medium of discharging from compressor 2, and detects the data (hereinafter referred to as " service data ") of the electric current of the drive motors of compressor 2 further.
The service data storage device 10 of equipment, primarily of formations such as CPU11, the first ~ three service data 16bit (position) memory 12,12a, 12b, the first ~ three differential data 8bit memory 13,13a, 13b, backup of memory 14, exceptional value file 15 and timers 16, records the service data of cooling and heating machine 1.
Sensor 8 obtains the various service datas of cooling and heating machine 1, and sends service data to CPU11.
In exceptional value file 15, preserve in advance for judging the data whether service data is abnormal.
Timer 16 sets 15 seconds as the sampling period, sends signal every the sampling period to CPU11.Here, the sampling period is the cycle of recording service data in the first service data 16bit memory 12 grade described later.
In addition, CPU11 receives service data with the cycle shorter than the sampling period from sensor 8, carries out the judgement whether service data is abnormal.This situation is also identical in embodiment 2 described later with embodiment 3.
Every 1 data are set to the capacity of 16bit by the first service data pressure data of 16bit memory 12 in order to blotter cold-producing medium, receive service data, line item of going forward side by side from CPU11.Equally, the second service data temperature data of 16bit memory 12a record-keeping system cryogen, the 3rd service data data of the electric current of the drive motors of 16bit memory 12b recording compressed machine 2.
Every 1 data, in order to the differential data of the pressure data of blotter cold-producing medium described later, are set to the capacity of 8bit by the first differential data 8bit memory 13, receive differential data, line item of going forward side by side from CPU11.Equally, the second differential data differential data of the temperature data of 8bit memory 13a record-keeping system cryogen, the 3rd differential data differential data of the data of the electric current of the drive motors of 8bit memory 13b recording compressed machine 2.
