Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, those of ordinary skill in the art obtained under not making creative work premise all other
Embodiment, broadly falls into the scope of protection of the invention.
As in figure 2 it is shown, the invention provides a kind of Power Supply Monitoring data parallel based on modbus agreement transmission system, bag
Including concentration battery-type inversion host control panel and supervising device, wherein, panel uses dsp chip as core processing core
Sheet, supervising device uses 51 series monolithics as kernel processor chip, passes through parallel data between panel and supervising device
Transmission channel carries out data transmission.
Parallel data transmission mode is the transmission having multiple data bit simultaneously to carry out between devices in the transmission.One volume
The character of code is typically to be represented by some bits, and the symbol as encoded with ASC I I code is by 8 bit tables
Show, then parallel transmission ASC I I coded identification is accomplished by 8 transmission channels, makes all data potential energies of one symbol of expression
Simultaneously along the transmission side by side of respective channel.The speed of parallel transmission is more faster than the speed of serial transmission.
Panel is provided with the A0 interface reading in and writing out control signal for Access Control plate data, is used for accessing judgement
Panel reads in or writes out the A1 interface of data validity signal, reads in and write out the D0-D7 Parallel I/O of data for panel
Interface.
Supervising device is provided with for accessing the P1.0 interface that supervising device data are read in and write out control signal, is used for connecing
Enter to judge that supervising device reads in or writes out the P1.1 interface of data validity signal, read in for supervising device and write out data
P0.0-P0.7 Parallel I/O Interface.RXD, TXD serial data port of supervising device, transmits port as external data.
Wherein, AO interface connects P1.0 interface, controls panel and the reading of supervising device data or writes out；A1 interface is even
Connect P1.1 interface, control panel and supervising device reads in or writes out the effectiveness of data；D0-D7 Parallel I/O Interface connects respectively
Connect P0.0-P0.7 Parallel I/O Interface, it is achieved the parallel transmission of data between panel and supervising device.
The control signal that the operation principle of the present invention: A0/P1.0 reads in as panel and supervising device data and writes out
Line, P1.1/A1 reads in as panel and supervising device or writes out data valid signal line；As it is shown on figure 3, when A0 low level,
During P1.0 high level, panel data are read in, and supervising device data are write out, and supervising device writes data into P0.0-P0.7 interface,
It is transferred to D0-D7 interface by parallel transmission channels, panel reads in data；Now, if P1.1 high level, represent that data have
Effect, if P1.1 low level, represents data invalid, by controlling the high/low level of P1.1, it is achieved panel reads in the change of data；
As shown in Figure 4, when A0 high level, P1.0 low level, panel data are write out, and supervising device data write, and panel is by number
According to write D0-D7 interface, it is transferred to P0.0-P0.7 interface by parallel transmission channels, supervising device reads in data；Now,
If A1 high level, represent that data are effective, if A1 low level, represent data invalid, by controlling the high/low level of A1, it is achieved control
Plate writes out the change of data.
The Data Transport Protocol of the panel of supervising device and main frame follows general modbus agreement, uses principal and subordinate's question and answer
Mode, carry out the quick transmission of data.Modbus agreement includes ASCI I, RTU, TCP etc., does not specify physical layer.
The rtu protocol of Modbus uses CRC check, this protocol defines the message structure that controller can recognize and use, regardless of
They through which kind of network communicate.The ASCI I of Modbus, rtu protocol define message, the structure of data, order
The mode just answered, data communication uses Maser/Slave mode, and Master end sends data request information, and Slave end receives
Master end just can be sent data to respond request after correct message；Master end can also directly messaging amendment
The data of Slave end, it is achieved two-way read-write, Modbus agreement uses catechetical communication mode, have simple, hardware cheap,
Highly versatile, advantage easy to use, easily exploitation and realization, follow modbus agreement outside supervising device with power supply and carry out
During serial data communication, supervising device can directly use with the transmission data of the panel of main frame.
The present invention is by using parallel transmission mode between the panel concentrating battery-type inversion main frame and supervising device
Transmission data, owing to panel is shorter with supervising device spacing, meet parallel transmission required distance, and solve power supply prison
Control device and the Data transmission by serial communication problem slowly of the panel of main frame, improve the ability that power supply controls in real time；Pass
Transmission protocol follows general modbus agreement, it is ensured that the accuracy of data transmission.
