FIELD: measurement equipment.
SUBSTANCE: integrated system of reserve instruments, comprising an orientation unit with a liquid-crystal screen connected to it. Also the following components are added: a device of battery recharge, a device of board grid voltage control, a device of battery voltage control, a device of short circuit protection, a voltage switchboard, a battery, the output of which is connected via the device of battery recharge to the board grid, via the device of battery voltage control to the first input of the orientation unit and via the device of protection to the first power input of the voltage switchboard, the second power input of which is connected to the board grid, and the power output - to the bus of the orientation unit power supply, the second input of which is connected to the control input of the voltage switchboard and the output of the board-grid voltage control, the input of which is connected to the board grid. Besides, the unit of orientation by signals of the first and second inputs generates information for a liquid-crystal screen, which displays the battery condition with symbols.
EFFECT: reliability improvement.
