Specific embodiment
Electri forklift stopping brake warning system is as shown in figure 1, including key switch 30, OPS seat switch 20, power supply 70
With parking switch 40, it is characterised in that the OPS（There is sensing in Operating Presence Sensing, operation）Seat
Chair switch 20 is built-in with the pressure sensor whether detection OPS seats are taken, and the power supply 70 is powered to electri forklift
Battery, the input of parking switch 40 is connected with power supply 70, and the output end of parking switch 40 is connected with relay 50, after
The coil of electrical equipment 50 simultaneously connects controller 10, and the output end of relay 50 is connected with the input of alarm 60, alarm 60 it is defeated
The output end for going out end ground connection, OPS seat switch 20 and key switch 30 is connected with the input port of controller 10, works as key switch
During 30 closure, controller 10 is adapted to detect for OPS seat switch 20 and the signal of key switch 30 and according to the signal control for being detected
The break-make of relay 10, alarm 60 in response to relay 50 and the break-make of parking switch 40, when key switch 30 disconnects,
Relay 50 is in normally off, break-make of the alarm 60 in response to parking switch 40.The controller 10 is that single-chip microcomputer is micro-
Controller.The alarm 60 includes following at least one：Buzzer, alarming horn and indicator lamp alarm.
Operation principle of the present utility model：
Referring to Fig. 1, when key switch 30 is closed, car load has electricity；Driver on the seat when, OPS switch closure.Control
Device 10 is in normal operating condition according to the signal determining car load of key switch 30 and OPS seat switch 20 for detecting, and thus controls
The output voltage of device processed 10 gives the coil of relay 50, makes the coil of relay 50 obtain electric, and the normal-closed end for making relay 50 disconnects.Now without
Whether on-position is in by parking switch 40, alarm 60 is all without work.
Referring to Fig. 2, when key switch 30 is closed, car load has electricity；When driver leaves seat, OPS is switched off.Control
Device 10 is in off position according to the signal determining car load of key switch 30 for detecting, and thus controller 10 disconnects relay 50
The voltage of coil-end, the coil of relay 50 is without electricity.When the coil of relay 50 is without electricity, the normal-closed end of relay 50 is in closes all the time
Conjunction state, now parking switch 40 be not on on-position（I.e. parking switch 40 is closed）When, alarm 60 is from power supply
70 ends obtain electric through parking switch 40, then through the normal-closed end of relay 50, and alarm 60 is started working.Until parking switch
40 are in on-position.Referring to Fig. 3, when driver is by the pull-up of parking switch 40（I.e. parking switch 40 disconnects）When, report to the police
The unpowered power supply 70 of device 60, does not work.
Referring to Fig. 4, when key switch 30 disconnects, when car load is without electricity, controller 10 and OPS seat switch 20 do not rise and appoint
What is acted on.Now parking switch 40 is not on on-position（I.e. parking switch 40 is closed）When, alarm 60 is from electric power storage
Chi Duan obtains electric through parking switch 40, again through the normal-closed end of relay 50, and alarm 60 is started working.Until parking switch
40 are in on-position.Referring to Fig. 5, when driver is by the pull-up of parking switch 40（I.e. parking switch 40 disconnects）When, report to the police
The unpowered power supply 70 of device 60, does not work.
