Type DF 8B diesel locomotive adopts logic control element circuit (being called for short LCU), realizes system without deaerator, thus improve the reliability of locomotive electric apparatus control circuit in appliance circuit.LCU utilizes modern electronic technology and micro-computer technology to form non-contact control circuit and instead of traditional contactor control circuit, the instruction Direct driver contactor even load sent with microcomputer, avoid the mode of current multiple drive power, greatly can simplify the contactor control circuit of locomotive like this, reduce aerial lug, improve the reliability of control system, reach the versatility of control system, LCU can also be connected with vehicle-mounted microcomputer communication control by data bus, realize resource sharing, achieve the relation of switching value and analogue enlargement, locomotive microcomputer display screen can demonstrate the situation that logic control exports.The impact of mechanical vibration, temperature, frequency interferences is subject to because locomotive is in operation; unit plug plug-in unit produces virtual connection to cause LCU logic control element to occur in the course of the work, occurs that fuel pump does not burn oil, diesel engine stop, auxiliary generator do not generate electricity, main generator is without phenomena of the failure such as stream are with no pressure.The condition of work of LCU must have input instruction signal, and input instruction signal, by exporting control signal after the process of system, makes appliance circuit normally work.So when handling failure, cannot differentiate the problem of external fault or LCU electronic package itself, blindly change LCU electronic package, its fault still exists, and even phenomenon of the failure is complicated.
Utility model content
In order to overcome above-mentioned technical matters, the utility model provides a kind of diesel locomotive microcomputer and the logic control device analog detection testing table that meet LCU electronic package following items measuring ability, EXP electronic package following items measuring ability and complete machine measuring ability, and the technical scheme of employing is as follows:
Diesel locomotive microcomputer and logic control device analog detection testing table, comprise master control borad, master control borad connects tablet and output board respectively, tablet comprises command signal input circuit and the first communicating circuit, output board comprises driving circuit and the second communicating circuit, described first communicating circuit and the second communicating circuit are linked in sequence LCU, microcomputer and display, and supply unit gives LCU, microcomputer and monitor power supply respectively.
Further, described LCU connects contactor.
Further, the input voltage of described supply unit is alternating current 220V, and output voltage is direct current 110V.
Adopt above-mentioned testing table according to practical operation Simulations on locomotive on ground, spatial dimension reduces, logical block LCU, microcomputer EXP, display DID and contactor working condition can be seen intuitively, and strong support and foundation are provided to the maintenance of some electronic cards and judgement, better determine that the scope point of locomotive failure is searched and processed, raising professional qualities are very helpful simultaneously, there is cost of manufacture low, applicability is strong, the advantages such as convenient operation.
