GPRS communication module and ethernet communication module, reseting module, display module, memory module and power module are and centralized control
Unit connection, central control unit are connect by GPRS communication module with server, and central control unit passes through ethernet communication
Module is connect with PC host.
5. a kind of transmission method of single type multiple terminals described in any one of Claims 1-4 low-consumption wireless Transmission system,
Characterized by the following steps:
The second wireless communication module of each terminal node unit is set node mode by the first step；
Second step, mode decision and switching module switch application scenarios according to order, and by the work of the first wireless communication module
Pattern switching is at operating mode corresponding with the application scenarios switched；
Third step, central control unit are communicated with multiple terminal node units, are sent and are controlled to multiple terminal node units
With read write command；
4th step, each terminal node unit receive and execute control and read write command, and operation knot is uploaded after completing order
Fruit and request data.
6. the transmission method of list type multiple terminals according to claim 5 low-consumption wireless Transmission system, it is characterised in that
In second step, mode decision and the process that switching module carries out application scenarios switching are as follows:
(1) according to order switching application scenarios, application scenarios include program renewal model, online tune for mode decision and switching module
Die trial formula and low power mode of operation；
(2) the application scenarios phase that the operating mode of the first wireless communication module is switched to and switched with switching mould by mode decision
Corresponding operating mode, specific as follows:
If a, application scenarios are switched to program renewal model, the operating mode of the first wireless communication module is switched to full speed work
Operation mode；
If b, application scenarios are switched to on-line debugging pattern, the operating mode of the first wireless communication module is switched to quickly logical
Road mode；
If c, application scenarios are switched to low power mode of operation, the operating mode of the first wireless communication module is switched to low function
Work consuming operation mode, i.e. center mode.
7. the transmission method of list type multiple terminals according to claim 5 low-consumption wireless Transmission system, it is characterised in that
In third step, central control unit is communicated with multiple terminal node units, to multiple terminal node units send control with
Detailed process is as follows for read write command:
(1) when central control unit is communicated with multiple terminal node units, command sending module judges multiple terminal nodes
Whether unit executes the same order, if multiple terminal node units execute the same order, enters second step, if multiple ends
When end segment dot element executes different command, then command sending module sends unit/terminal node orders to corresponding terminal node list
Member；
(2) command sending module judges whether the energy consumption of a multiple terminals node orders is less than multiple unit/terminal node orders
Energy consumption, if so, command sending module sends a multiple terminals node orders to each terminal node unit, if it is not,
Then command sending module sends multiple unit/terminal node orders to corresponding terminal node unit.
8. the transmission method of list type multiple terminals according to claim 5 low-consumption wireless Transmission system, it is characterised in that
In third step, communicated between central control unit and multiple terminal node units using proprietary protocol, the proprietary protocol packet
Include multiple terminals node orders processing data frame, unit/terminal node orders processing data frame, terminal node unit upload data frame or
Acknowledgement frame；Data frame includes receiving end address, command code, sends byte number, order data, cyclic redundancy check；Multiple terminals node orders
The receiving end address of data frame is broadcast address, and unit/terminal node orders data frame and terminal node unit upload the receiving end of data frame
Address is counterpart terminal node unit address.
9. the transmission method of single type multiple terminals low-consumption wireless Transmission system, feature according to claim 5 or 8 exist
In further including terminal node unit after completing to order upload operation result and request data, central control unit is according to each end
The reply frame of end segment dot element retransmits data into retransmission module, specific as follows:
(1) retransmission module judges whether to need to retransmit according to the reply frame of each terminal node unit, in response to needing to retransmit,
Then all data frames that need to be retransmitted are packaged to generate and retransmit data；
(2) end time executed according to the previous command, at the beginning of setting retransmits and time interval, transmission retransmit data
Packet；
(3) judge whether normally to have sent re-transmission data packet, send if normal, stop retransmitting, if there are the data not sent normally
Frame then goes successively to retransmission module for not normal data frame；
(4) retransmission module judges whether number of retransmissions is greater than threshold number, if more than then reducing priority, being transferred to week for a long time
The heartbeat packet of phase is inquired, if being not more than, repeats (2) to (3) step.
