Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-5, a system for remotely updating a control program mainly comprises a control motherboard, a 485-to-232 module, and a DTU module.
The control mainboard is a core control component of the heating equipment, a control IC (CPU) is arranged in the control mainboard, and a program for controlling the operation of the heating equipment is burnt in the control IC. The control mainboard is also provided with a data input port, an output port and a communication port, and the control IC is respectively connected with the data input port, the signal output port and the communication port. The data input port is used for connecting temperature, pressure and other signal sensors of heating and heat supply equipment, the control IC receives temperature data, pressure data and abnormal information of the equipment in the operation of the heating and heat supply equipment through the data input port, the temperature information generally acquired by the heating and heat supply equipment comprises fin temperature, exhaust temperature, suction temperature, temperature after a valve, hot water temperature, ambient temperature and system evaporation and return temperature, and the pressure data comprises water pump pressure and press pressure. When the equipment has the problems of temperature, pressure abnormity or power failure and the like, the control IC regulates the working states of the water pump, the press and the electric heating element through the output port so as to solve the problem of data abnormity, and controls the heating equipment to stop and warn when the fault which can not be regulated occurs. The communication port of the control mainboard is used for carrying out data interaction with an external computer platform and feeding back the working state of the heating equipment in real time, and the communication port has the purpose of remotely updating programs. The communication port adopts RS485 bus, uses the agreement of standard MODBUS, for the function of realizing long-range update procedure, and control IC is connected with the communication port electricity in the control mainboard, and the communication port carries out communication connection through 485 commentaries on classics 232 module and DTU module.
The DTU module is provided with an antenna, a flow card, a FLASH memory, a CPU control port and a power supply port. The DTU module is in wireless connection with an external computer platform through an antenna and a flow card, and the computer platform downloads program data to be updated into a FLASH memory of the DTU module through wireless data transmission. The DTU module has an ID with unique identification, and when the computer platform is connected with the DTU modules, the corresponding DTU modules can be uniquely identified. The power supply port is connected with an external power supply, the power supply port adjusts the input voltage of the power supply through the power adapter, and the range of the input voltage is +9VDC to +36VDC so as to meet the normal use requirement of the DTU module. The CPU control port is connected with a 485-to-232 module, and the 485-to-232 module is connected with a communication port of the control mainboard. In the system for remotely updating the control program, a control mainboard with the model number of LK55528A, a 485-to-232 module with the model number of GW123B and an industrial DTU module with the model number of H7710C can be adopted.
