raspberry pi3にて、温度、湿度、気圧を計測し、ｍilkcocoaにpushするプログラムを作成し、 crontabにて5ヶ月ほど運用してきましたが、ここ数日、安定して計測できなくなり、直接コマンドを入力した所、数回に一度、[Errno 32] Broken pipeと表示され、 milkcocoaにpushできていません。原因はなんでしょうか。どうやら、以下のプログラムでエラーになっているようです。 def on_push(e): print(e) エラー場所1 push_start on_push_end temp_end on_push_end humid_end [Errno 32] Broken pipe on_push_end pressure_end エラー場所2 push_start on_push_end temp_end [Errno 32] Broken pipe on_push_end humid_end on_push_end pressure_end ```python #coding: utf-8 import sys import smbus import time import datetime import milkcocoa.milkcocoa as milkcocoa milkcocoaClient = milkcocoa.Milkcocoa.connectWithApiKey("****", "****", "***", useSSL=False,blocking=True) temp = milkcocoaClient.datastore("temp") humid = milkcocoaClient.datastore("humid") pressure = milkcocoaClient.datastore("pressure") bus_number = 1 i2c_address = 0x76 bus = smbus.SMBus(bus_number) digT = [] digP = [] digH = [] t_fine = 0.0 sensor_data = {'temp':'0.0', 'pressure':'0.0','humidity':'0.0'} def on_push(e): print(e) def writeReg(reg_address, data): bus.write_byte_data(i2c_address,reg_address,data) def get_calib_param(): calib = [] for i in range (0x88,0x88+24): calib.append(bus.read_byte_data(i2c_address,i)) calib.append(bus.read_byte_data(i2c_address,0xA1)) for i in range (0xE1,0xE1+7): calib.append(bus.read_byte_data(i2c_address,i)) digT.append((calib[1] << 8) | calib[0]) digT.append((calib[3] << 8) | calib[2]) digT.append((calib[5] << 8) | calib[4]) digP.append((calib[7] << 8) | calib[6]) digP.append((calib[9] << 8) | calib[8]) digP.append((calib[11]<< 8) | calib[10]) digP.append((calib[13]<< 8) | calib[12]) digP.append((calib[15]<< 8) | calib[14]) digP.append((calib[17]<< 8) | calib[16]) digP.append((calib[19]<< 8) | calib[18]) digP.append((calib[21]<< 8) | calib[20]) digP.append((calib[23]<< 8) | calib[22]) digH.append( calib[24] ) digH.append((calib[26]<< 8) | calib[25]) digH.append( calib[27] ) digH.append((calib[28]<< 4) | (0x0F & calib[29])) digH.append((calib[30]<< 4) | ((calib[29] >> 4) & 0x0F)) digH.append( calib[31] ) for i in range(1,2): if digT[i] & 0x8000: digT[i] = (-digT[i] ^ 0xFFFF) + 1 for i in range(1,8): if digP[i] & 0x8000: digP[i] = (-digP[i] ^ 0xFFFF) + 1 for i in range(0,6): if digH[i] & 0x8000: digH[i] = (-digH[i] ^ 0xFFFF) + 1 def readData(): data = [] for i in range (0xF7, 0xF7+8): data.append(bus.read_byte_data(i2c_address,i)) pres_raw = (data[0] << 12) | (data[1] << 4) | (data[2] >> 4) temp_raw = (data[3] << 12) | (data[4] << 4) | (data[5] >> 4) hum_raw = (data[6] << 8) | data[7] compensate_T(temp_raw) compensate_P(pres_raw) compensate_H(hum_raw) def compensate_P(adc_P): global t_fine pressure = 0.0 v1 = (t_fine / 2.0) - 64000.0 v2 = (((v1 / 4.0) * (v1 / 4.0)) / 2048) * digP[5] v2 = v2 + ((v1 * digP[4]) * 2.0) v2 = (v2 / 4.0) + (digP[3] * 65536.0) v1 = (((digP[2] * (((v1 / 4.0) * (v1 / 4.0)) / 8192)) / 8) + ((digP[1] * v1) / 2.0)) / 262144 v1 = ((32768 + v1) * digP[0]) / 32768 if v1 == 0: return 0 pressure = ((1048576 - adc_P) - (v2 / 4096)) * 3125 if pressure < 0x80000000: pressure = (pressure * 2.0) / v1 else: pressure = (pressure / v1) * 2 v1 = (digP[8] * (((pressure / 8.0) * (pressure / 8.0)) / 8192.0)) / 4096 v2 = ((pressure / 4.0) * digP[7]) / 8192.0 pressure = pressure + ((v1 + v2 + digP[6]) / 16.0) # print "pressure : %7.2f hPa" % (pressure/100) sensor_data['pressure'] = pressure/100 def compensate_T(adc_T): global t_fine v1 = (adc_T / 16384.0 - digT[0] / 1024.0) * digT[1] v2 = (adc_T / 131072.0 - digT[0] / 8192.0) * (adc_T / 131072.0 - digT[0] / 8192.0) * digT[2] t_fine = v1 + v2 temperature = t_fine / 5120.0 # print "temp : %-6.2f 邃・ % (temperature) sensor_data['temp'] = temperature def compensate_H(adc_H): global t_fine var_h = t_fine - 76800.0 if var_h != 0: var_h = (adc_H - (digH[3] * 64.0 + digH[4]/16384.0 * var_h)) * (digH[1] / 65536.0 * (1.0 + digH[5] / 67108864.0 * var_h * (1.0 + digH[2] / 67108864.0 * var_h))) else: return 0 var_h = var_h * (1.0 - digH[0] * var_h / 524288.0) if var_h > 100.0: var_h = 100.0 elif var_h < 0.0: var_h = 0.0 # print "hum : %6.2f ・・ % (var_h) sensor_data['humidity'] = var_h def setup(): osrs_t = 1 #Temperature oversampling x 1 osrs_p = 1 #Pressure oversampling x 1 osrs_h = 1 #Humidity oversampling x 1 mode = 3 #Normal mode t_sb = 5 #Tstandby 1000ms filter = 0 #Filter off spi3w_en = 0 #3-wire SPI Disable ctrl_meas_reg = (osrs_t << 5) | (osrs_p << 2) | mode config_reg = (t_sb << 5) | (filter << 2) | spi3w_en ctrl_hum_reg = osrs_h writeReg(0xF2,ctrl_hum_reg) writeReg(0xF4,ctrl_meas_reg) writeReg(0xF5,config_reg) setup() get_calib_param() if __name__ == '__main__': try: readData() time_str = datetime.datetime.today().strftime("%Y/%m/%d %H:%M:%S") temp_str = str(sensor_data['temp']) humid_str = str(sensor_data['humidity']) pressure_str = str(sensor_data['pressure']) #milkcocoa縺ｫ繝・・繧ｿ繧恥ush縺吶ｋ縲・ print("push_start");
