The purpose of the present invention is directed to the relatively low problem of batch inspection automation degree, devises a kind of underground coal mine D.C. regulated power supply automatic detection device.
The technical solution adopted for the present invention to solve the technical problems is：
Underground coal mine D.C. regulated power supply automatic detection device is made up of AC voltage adjusting unit, information gathering and control unit, test product selection control unit, 4 parts of fictitious load and voltage x current collecting unit.
Described AC voltage adjusting unit uses three groups of pressure regulators, and interlocking break-make is carried out to its AC220 V input by relay is controlled, and realizes three groups of switchings of pressure regulator, and interlock function is realized by PC control software.
Described information gathering and control unit are using 3 sets of coal science and technology research institute Coal Mine Safety Monitoring Systems substation mainboard, often set mainboard can realize 16 road analog inputs, 8 tunnel controlled quentity controlled variable outputs, while can realize being communicated with host computer by RS485 buses.The system uses the tunnel of analog input signal 26 altogether, and the tunnel of controlled quentity controlled variable output signal 19 can meet use demand and extend demand in the future using 3 sets of Coal Mine Safety Monitoring Systems substation mainboards.
The purpose of design of described test product selection control unit is, to realize that 10 10 tunnel direct current outputs of test product are connected with " fictitious load and voltage x current collection display unit " in turn, and then to realize the display of detection voltage current data and upload host computer.
Described fictitious load unit uses various its load forms such as " electronic load " simulation short circuit, open circuit, full load, using the voltage with analog output, ammeter display information, and measurement data is uploaded to host computer in analog quantity form through " signal acquisition and controlling unit ".
The beneficial effects of the invention are as follows：
The design of underground coal mine D.C. regulated power supply automatic detection device, the collection for realizing voltage x current data shows and uploads, it is achieved thereby that the switching of the electronization of inspection data, automatic Regulation and automatic test product, improves the automaticity of device.The design of this device, fundamentally solves the present situation that underground coal mine D.C. regulated power supply lacks efficient, portable Aulomatizeted Detect means, while improve detection efficiency and accuracy.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is hardware General layout Plan figure.
Fig. 2 is AC voltage adjusting unit conceptual schematic drawing.
Fig. 3 is test product selection control principle drawing.
Specific embodiment
As shown in figure 1, system design is divided into AC voltage adjusting unit, information gathering and control unit, test product selection control unit, 4 parts of fictitious load and voltage x current collecting unit.After the completion of design, can realize that 10 automatic imitation AC networks of test product fluctuate, various its load forms such as simulation short circuit, open circuit, full load, while the electronic measurement data that electronic instrument is detected, by information gathering and control unit to upper computer software, for data analysis provides basic data.10 test products can realize automatic change detection in turn.By fully demonstration, the design is using RS485 buses and analog input, the second order hierarchical distributed network structure of controlled quentity controlled variable output.Information gathering communicates using RS485 bus modes with control system with host computer, and information gathering communicates by the way of analog input and controlled quentity controlled variable output with control system with AC voltage adjusting unit, test product selection control unit and fictitious load and voltage x current collecting unit.Network structure uses stelliform connection topology configuration, and transmission medium is two core twisted-pair feeders between mobile communication device.Systems soft ware is based on coal science and technology research colliery Safety monitoring systems soft ware, perfect in shape and function is carried out on this basis, realize voltage, the collection of current data, display, the output function of form, the mutual lock control in three tunnels to ACVV system and the control of automatic Regulation signal are realized simultaneously, realize the interlocking switching control to 10 road test products.Systems soft ware has operator's privilege feature simultaneously, can realize recording the operation note of different inspectors, and then meets the requirement of ISO9001 systems, realizes inspection recorded electronic.
As shown in Fig. 2 the design realization exchange input of this unit AC127V, 380V, 660V fluctuate in the range of 75% ~ 110%, while realizing three groups of voltages interlocking power supplies, and the voltage of pressure regulation output, current signal are sent to host computer and shown.This unit uses three groups of pressure regulators, and interlocking break-make is carried out to its AC220 V input by relay is controlled, and realizes three groups of switchings of pressure regulator, and interlock function is realized by PC control software.Pressure regulator selects electronic pressure controller, and every group by two Controls, pressure regulation is realized in its rotating.Pressure regulation result is shown by volometer, and is uploaded to host computer through " signal acquisition and controlling unit " by 4 ~ 20mA of analog quantity signals, and for detection, operator confirms to pressure regulation result.
As shown in Figure 3, test product selection control unit this unit purpose of design is, to realize that 10 10 tunnel direct current outputs of test product are connected with " fictitious load and voltage x current collection display unit " in turn, and then to realize the display of detection voltage current data and upload host computer.Design uses " information gathering and control unit " controlled quentity controlled variable output control relay, relay to control handover module again, and the 10 tunnel direct current outputs to 10 test products are switched over.Upper computer software is interlocked to 10 groups of controlled quentity controlled variables, to ensure examined for 1 in tested 10 unit of the product times.
