The process of power-up initializing is to the detection of host computer and slave computer interface, comprising: RS485 interface, RS232 interface.Judge whether each interface is working properly, detect failure and show failure code by rule, and the work below continuing.Initialization MODEM after interface detects and finishes.2. the Long-distance Control detector reads the air-conditioning initial condition:
If free of data among the EEPROM then signals to the 1# air-conditioning, upload air-conditioning state is set, then do not show failure code if receive data by rule, change the work of " 3. whether the cycle detection host computer has data to transmit " over to.
If among the EEPROM data are arranged, set to air conditioner transmission data according to single two-shipper.If unit is sent out Data Control 1# air-conditioning, whether working properly according to the return data judgement, failure shows failure code by rule, changes the work of " 3. whether the cycle detection host computer has data to transmit " over to.If two-shipper, send out Data Control 1# air-conditioning earlier, whether working properlyly judge according to return data, change the work of " 3. whether the cycle detection host computer has data to transmit " over to, failure shows failure code by rule, then control 2# air-conditioning, failure shows failure code by rule, changes the work of " 3. whether the cycle detection host computer has data to transmit " over to.3. whether the cycle detection host computer has data to transmit:
There is 0# to interrupt detecting the RS485 interface, finishes receiving data and judging the address, if correctly then change the processing of " 4. sending control air conditioner data " over to; If do not have interruption or do not receive data or address and this machine mail returned on ground of incorrect address, then change over to and judge that 1# interrupts.
There is 1# to interrupt detecting the RS232 interface, finishes the reception data, if correctly then change the processing of " 4. sending control air conditioner data " over to; If do not have to interrupt or do not receive the then following work of circular treatment of data: reader machine address, detected temperatures, open interruptions, whether detection has interruption.4. send control air conditioner data:
After receiving valid data, finish the control air-conditioning and the data of returning are sent to host computer.
If unit is sent out Data Control 1# air-conditioning, judge whether working properly, normal then the data of returning are sent to host computer according to return data.
If two-shipper is sent out Data Control 1# air-conditioning earlier, whether working properlyly judge according to return data, normal then the data of returning are sent to host computer, failure shows failure code by rule, then control 2# air-conditioning, failure shows failure code by rule, and the data of returning are sent to host computer.
After the data of returning are sent to host computer, change the work of " 3. whether the cycle detection host computer has data to transmit " over to.
With reference to Fig. 7-1,7-2, the control procedure of remote centralized controller also can be divided into 4 parts: 1. the power-up initializing of remote centralized controller:
The process of power-up initializing is to the detection of host computer and slave computer interface, comprising: RS485 interface, RS232 interface.Judge whether each interface is working properly, detect failure and show failure code by rule, and the work below continuing.Initialization MODEM after interface detects and finishes is provided with plane No..2. whether the cycle detection host computer has data to transmit:
Interruption is opened in reader machine coded address, prepares to receive data.
Interruption (request of data) is arranged, and first connection line receives the RS232 interface data, if failure then reconnects circuit, till receiving data, receives and correctly then writes buffer memory.
Do not have to interrupt (request of data), then according to the processing that data in buffer directly changes follow-up work over to that writes of remote centralized controller.3. circular treatment valid data (send control Long-distance Control detector (air conditioner) data):
(1) circulation is read data cachedly, finishes the setting to each plane No. representative air-conditioning.
(2) send control data: read data cached and the plane No. address is set, send control data, receive the return state data, show or air-conditioning state that storage is returned by plane No. is set; Whether working properly according to the return data judgement, failure shows failure code by rule, changes the follow-up work processing over to.
If the control command that host computer is sent (RS232 interface or MODEM data), then the status data that the Long-distance Control detector is returned sends to host computer (by RS232 interface or MODEM data), and, change " 2. whether the cycle detection host computer has data to transmit " over to the Centralized Controller standby.4. if not the control command that host computer is sent, then change " 3. (2) send control data " circular treatment over to the air-conditioning of plane No. respectively is set, promptly write data being set and the plane No. address cycle is set and handling of buffer memory according to the remote centralized controller.
