Brief description of the drawings
Fig. 1 is present system composition figure；
Fig. 2 is passage switch unit schematic diagram of the present invention；
Fig. 3 is present system workflow.
Embodiment
As shown in figure 1, a kind of changeable insulation monitoring and warning device of multichannel, including MCU controls and arithmetic element, communication unit
Member, measuring unit, passage switch unit and input interface unit；
Described input interface is made up of multiple measurement interfaces in parallel, and all measurement interfaces are both connected to passage switching
On unit；
Described passage switch unit is made up of multiple high-voltage relays in parallel, high-voltage relay control pin and load
Pin electrical isolation.Multiple high-voltage relays in parallel are controlled with MCU and the control port of arithmetic element is connected, multiple in parallel
High-voltage relay is by controlling pin and the input of multiple measurement interfaces in parallel to be connected；
The signal acquisition terminal of described measuring unit is connected with the output end of multiple measurement interfaces in parallel, measuring unit
Signal output part is controlled with MCU and arithmetic element is connected, and signal sending end and the communication unit of MCU controls and arithmetic element connect
Connect.
Measuring unit described in the utility model is unbalanced bridge observation circuit.
Communication unit described in the utility model includes CAN communication interface, RS232 interface and RS485 interfaces.
Referring to Fig. 2, a kind of passage switch unit operation principle of the changeable insulation monitoring and warning device of multichannel is that MCU passes through control
CH1+ processed, CH1-, CH2+, CH2-, CH3+, CH3- output level can control the input CH1_DC+, CH1_ of Measurement channel
DC-, CH2_DC+, CH2_DC-, CH3_DC+, CH3_DC- are connected to the input DC+ and DC- of measuring unit.If necessary to survey
One passage of flow control, control port CH1+ and the CH1- pin of respective channel is put into high level, now high-voltage relay RLY1 and
RLY2 pin is in normally off, CH1_DC+ and DC+ conductings, and CH1_DC- and DC- conductings, DC+ connect insulating monitoring with DC-
The measuring unit of device, CH1_DC+ and CH1_DC- now connect with DC- with the measuring unit of insulation monitoring and warning device.It is similarly controllable
Passage 2 and passage 3 processed turn on measuring unit.
Referring to Fig. 3, a kind of workflow of the changeable insulation monitoring and warning device of multichannel is carried out first after electricity on device
Initialization, initialization include the initialization of hardware and software, and wait first detects whether to need into row of channels after initializing successfully
Switching, enters row of channels switching if desired, starts passage switching first, corresponding logical by controlling the conducting of high-voltage relay to gate
Road waits passage just to proceed by real time data measurement after switching successfully, MCU starts after DATA REASONING success to collecting unit
Measurement result is calculated by computing, after measurement result comes out, MCU is uploaded measurement result by communication unit, measurement result
Upload this measurement that succeeds terminates, and device will start the measurement of next passage.
