Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described further:
Please refer to Fig. 1, it is the schematic diagram of structure function experimental control device of the present invention.Described structure function experimental control device comprises signal input module, signal conversion module, control circuit.Wherein, signal input module receives external signal, and is connected with signal conversion module, and signal conversion module connects control circuit, and control circuit controls hydraulic pump by the output of some parallel connections and valve is realized the control to testpieces.
Please refer to Fig. 2, described control circuit comprises power supply, holding circuit and executive circuit.Holding circuit is relay, and with the power output end that is connected external signal and is connected, is arranged on control circuit, the relay group that executive circuit is some parallel connections, is connected to output, and connecting fluid press pump Ji Fa class topworks, comprises interlocking output circuit in relay group respectively.
Described control protection module is a relay, is connected with external system, is all connected with signal conversion module and control circuit simultaneously.Under control system normal operating condition, this unit protection circuit receives system signal, protective relay action, each circuit normal power supply of assurance device, work; Otherwise device quits work.
Described executive circuit is the relay group of some parallel connections, is connected to output, and connecting fluid press pump Ji Fa class topworks, comprises interlocking output circuit in relay group respectively.Its input receives the information from system, by the relay group that conversion and control is different, moves, and corresponding output end output matching voltage, controls the respective execution mechanisms actions such as hydraulic pump, completes the folding and unfolding of test specimen is controlled.
The principle that structure function experimental control device of the present invention is simplified in line with refining, the information relevant to control and safeguard protection that only receiving control system is exported, other scene or system information conform to the principle of simplicity to process.Reduce like this component number, also reduced connectivity port, and made control panel short and sweet; According to systematic parameter index, reasonable standard input and output parameter, reduces Power supply and intermediate circuit simultaneously, makes configuration compact, installs light.
Please refer to Fig. 3, take undercarriage control as example, the whole process of its folding and unfolding is divided into four steps, is respectively to receive, load transfer in receipts, put down, put down load transfer, often executes this four steps undercarriage and completes one and rise and fall.Such as, when undercarriage stowage, first complete down lock release action, structure function control device receiving control system signal, after its internal signal conversion, determines the actuating of relay in the executive circuit in control circuit, control hydraulic pump and open corresponding oil circuit, complete down lock release; Meanwhile, interlock circuit assurance device is not carried out down lock locking order, prevents control system false triggering and performs an action and make mistakes.
