A communication management machine of monitoring system for enterprise substation comprises a host computer; a CPU processor, an LED display unit, a power processing unit and a device configuration unit are arranged inside the host computer; the host computer is also provided with an expansion interface unit which is provided with a plurality of RS 232 or RS 485 interfaces and is connected with a plurality of electricity instruments through the RS 232 or RS 485 interfaces; the host computer also comprises an Ethernet processing unit and is connected with at least two HMI computers through the Ethernet processing unit. A single device can be allocated with 20 expanded RS 232 or RS 485 interfaces at most and the amount of the interfaces is optional; the protocol of each interface is optional; thereby the problem of product compatibility of different enterprises is solved. The machine has Ethernet interfaces, uniformly supports the Modbus TCP function and can connect with at least two HMI computers.
Description
Technical field
The present invention relates to communication management machine of monitoring system for enterprise substation.
Background technology
The data acquisition system (DAS) ubiquity acquisition speed of the transformer station that has much built up in the present transformer station of enterprise is slower, and the data and the warning that cause the user to see are delayed retardation time.There is the restriction of the equipment of type selecting equally for newly-built system, the equipment great majority that can cause the user to select all are the equipment of the half-duplex agreement of RS485, because the cost that updates is too high, so most of user for the consideration of cost, has to stand data long shortcoming retardation time.Refresh Data makes the demonstration of data have slowly must hysteresis quality, can cause the user can be with reference to the property variation to data, and the delay of warning can cause the possibility of device damage to strengthen more.
Existing systems also has a shortcoming, owing to be that semiduplex equipment can cause the user simultaneously a main frame monitoring data can only be arranged.After going offline, monitoring host computer can cause loss of data, many HMI machine communication monitoring simultaneously.At present domestic this transformer station has and much builds up, and newly-built needs, and the user mainly needs to gather voltage, electric current, signals such as electric energy.And for the situation of the transformer station that transforms, the user does not wish to change all instrument.And the function of cheap instrument can not be broken away from the situation of this embarrassment.Also there is the trouble of this respect in transformer station of newly-built enterprise.
Our device design can solve at present above these problems:
(1), system adopts many RS485/RS232 mouth while and issues device talk, communication data is stored in the memory field of this machine, transmit into Ethernet ModbusTCP and give machine, so just by the high speed communication performance of concurrent communication simultaneously and Ethernet solved the problem of the data rate of host computer.
(2), because our communication manager is to adopt ethernet communication concurrent at least two each and every one communications simultaneously to connect, and the user can connect 2 above HMI computer equipments simultaneously like this, the while can be passed to interior any remote monitoring computer equipment.
(3), the solution that differs for the instrument communications protocol.The driving of our equipment contains the communications protocol of great majority electric instrument commonly used.For special rare communications protocol we can by after the exploitation more New Deal address this problem.
Equipment possesses good equipment compatibility, is applicable to the transformation of most old systems, and the type selecting of transformer station of newly-built enterprise needs get everything ready very big market outlook and promotional value.
Our communication manager can not transformed under the situation of original ammeter the user, adds some communication cables and original software is carried out some transformations can finish, and expense is low, construction volume is little, construction period is short.The at present domestic communication manager of also not transforming at the user of transformer station of enterprise, our product also are that newly-built transformer station addresses the aforementioned drawbacks a selection is provided.
Summary of the invention
The purpose of this invention is to provide a kind of communication management machine of monitoring system for enterprise substation, fill up domestic blank, can use for enterprise's monitoring system of electric substation upgrading communication apparatus.
Technical scheme of the present invention:
Communication management machine of monitoring system for enterprise substation, comprise main frame, inner CPU processor, led display unit, power supply processing unit, the equipment disposition unit installed of main frame, also be provided with extended interface unit on the main frame, described extended interface unit is provided with some RS232/RS485 interfaces, is connected with some electric instruments by the RS232/RS485 interface.
Described main frame further comprises Ethernet processing unit, and main frame is connected with at least two HMI computing machines by Ethernet processing unit.
Single device can be expanded 20 RS232/RS485 ports at most, can select port number; The communications protocol of each port can be selected, and can solve the problem of different manufacturers Products Compatibility like this; Contain Ethernet interface, the unified Modbus TCP function of supporting can connect at least 2 HMI machines simultaneously.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structured flowchart of communication management machine of monitoring system for enterprise substation of the present invention.
Among the figure: 1, main frame; 2, electric instrument; 3, HMI machine.
Embodiment
With reference to figure 1, communication management machine of monitoring system for enterprise substation of the present invention, comprise main frame 1, main frame 1 inner CPU processor, led display unit, power supply processing unit, the equipment disposition unit installed, also be provided with extended interface unit on the main frame, described extended interface unit is provided with some RS232/RS485 interfaces, is connected with some electric instruments by the RS232/RS485 interface; Led display unit can show the operation conditions of each monitored electric instrument 2 in the whole monitoring system, is breaking down or data transmission can be reported to the police when going wrong.
Described main frame 1 further comprises Ethernet processing unit, and main frame 1 is connected with at least two HMI computing machines 3 by Ethernet processing unit, adopts in parallel between the HMI machine 3.
Single device can be expanded 20 RS232/RS485 ports at most, can select port number arbitrarily; The communications protocol of each port can be selected, and can solve the problem of different manufacturers Products Compatibility like this; Contain Ethernet interface, the unified Modbus TCP function of supporting can connect at least 2 HMI machines 3 simultaneously, when the damage of section H MI machine can not be played supervisory function bit to instrument, can realize by other HMI machines 3 like this.
We adopt 1 ARM CPU processor as can be seen as shown in the figure, contain the Linux embedded system, are used for system protocol and transmit and internal system work.The communications protocol forwarding capability.That adopts embedded system is that a little the secondary development difficulty reduces greatly, and the compatibility of system is strengthened greatly.
Main chip adopts: LPC3180, MAX232, MAX485 etc.
