Description
Technical field
The utility model relates to a kind of special-purpose UPS of electric power of the MODBUS of satisfying agreement, it is a kind of alternating current-direct current dual input, the supply unit that exchanges output, satisfy the designing requirement of power industry power plant system fully, have characteristics such as safe and reliable, intelligent degree height, improved the automatic management level of power plant.
Background technology
The MODBUS agreement is that MODICON company under the Schneider is used for electronic controller in invention in 1978 a kind of and controls communications protocol with communication.By this agreement, controller each other, controller is via communicating between network (for example Ethernet) and the miscellaneous equipment.Its opening, expandability and standardization make it become a universal industrial standard.It has been arranged, and the control appliance that different vendor produces can be linked to be industrial network simple and reliablely, carries out the centralized monitor of system, thereby makes it become one of procotol of most popular industrial control unit (ICU).China adopts this standard at present in the power plant system of power industry.After adopting this standard, the various control appliances in the power plant just can clog-free access power plant DCS system, and the automatization level that this has just improved the power plant greatly realizes the unattended operation and the remote monitoring of power plant equipment.The special-purpose UPS of common electric power has only communications protocol and RS-232 or the RS-485 communication interface of oneself, can only use special bitcom to carry out the communication of point-to-point or point-to-multipoint when needing communication.Owing to do not satisfy the MODBUS agreement, so can't insert in the power plant DCS system.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of special-purpose UPS of electric power that satisfies the MODBUS agreement is proposed, this UPS adopts dual-cpu structure, and 485 interfaces that satisfy the MODBUS agreement that link to each other with the external world can be provided, thereby in can clog-free access power plant DCS system.
The purpose of this utility model is achieved through the following technical solutions: the special-purpose UPS of electric power that satisfies the MODBUS agreement; be provided with housing; circuit board; it is characterized in that: described circuit board is provided with by input unit; the input filter unit; the input isolated location; rectification unit; inversion unit; the output isolated location; the output filter unit; the bypass switch unit; the mains supply line that output unit connects to form successively; also be provided with on the described circuit board by the bypass input unit; voltage regulation unit is isolated in bypass; the inferior supply line that the bypass switch unit connects to form successively; mains supply line switches power supply with time supply line by the bypass switch unit; the bypass switch unit is by feedback unit and protection control unit control connection, rectification unit; inversion unit; the bypass switch unit respectively with protection control unit control connection.
The execution mode that the utility model further improves and replenishes:
Described protection control unit is connected with the communication unit data by telecommunication cable.
Described protection control unit is connected with complete machine monitoring display data by data wire.
Employing dual-cpu structure of the present utility model, single chip computer AT MAGA128 links to each other with rectification unit, inversion unit, bypass switch unit, feedback unit, complete machine monitoring display unit, links to each other with the MSP430F147 single-chip microcomputer by 232 interfaces.The MSP430F147 single-chip microcomputer reads operational factors such as the input voltage, input current, output voltage, output current, direct voltage, frequency of UPS according to the agreement of UPS itself, change accordingly according to the data format of MODBUS agreement again, the data that will satisfy the MODBUS agreement at last output to 485 interfaces that link to each other with the external world, improve the automatization level in power plant greatly, realized the unattended operation and the remote monitoring of power plant equipment.
