Abstract
The utility model discloses an empty-vehicle indicating lamp controller, and belongs to the field of taxi empty-vehicle indicating lamp control. The controller comprises a power supply, a time relay and a passenger detection unit. The passenger detection unit comprises several microswitch with normally closed contacts. One of the microswitches is arranged on the bottom portion of an auxiliary diver seat. The other microswitches are distributed on the bottom portion of the seats of a rear row at equal intervals. The normally closed contacts of the microswitches are sequentially in series connection. The power supply is connected to a coil of the time relay through the passenger detection unit. A normally open contact of the time relay is connected with an empty-vehicle indicating lamp. The empty-vehicle indicating lamp controller of the utility model can control the empty-vehicle indicating lamp according to passenger-carrying conditions in a vehicle, so that a phenomenon that passengers are mislead due to that a driver forget to operate is avoided.
Description
Technical field
The utility model relates to a kind of empty indicating lamp controller, belongs to taxi empty pilot lamp control field.
Background technology
In regular taxi, be all provided with empty indicating lamp, for giving the people's prompting vehicle outside car whether unloaded.In the time that taxi does not have carrying, taxi driver can open empty indicating lamp, to solicit passenger; In the time of taxi carrying, taxi driver should close empty indicating lamp, to prevent people's pushing-off the wagons.But in actual life, some taxi drivers can forget and close empty indicating lamp in the situation that of carrying, these people that can call a taxi to needs cause misleading.
Utility model content
The purpose of this utility model is: propose a kind of empty indicating lamp controller, to realize the automatic switch of empty indicating lamp.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of empty indicating lamp controller, comprises power supply, the time relay and occupant detection unit; Described occupant detection unit comprises several microswitches with normally closed contact, and one of them microswitch is located at the bottom of assistant driver seat, and all the other microswitches are equidistantly distributed in the bottom of back row seats, and the normally closed contact of all microswitches is connected successively; Described power supply is connected with the coil of the time relay by occupant detection unit; The normally opened contact of the described time relay is connected with empty indicating lamp.
Preferably, the described time relay adopts the direct current time relay.
Preferably, described power acquisition alkaline battery.
Technique effect:
1, can automatically control empty indicating lamp according to the carrying situation of taxi, avoid, because driver forgets operation, the people that will call a taxi is caused to misleading.
2, adopt the time relay to control empty indicating lamp, can avoid occurring because passenger leaves situation about seat being lighted by empty indicating lamp the short time.
3, circuit structure is simple, realizes difficulty lower, and application prospect is good.
Accompanying drawing explanation
Fig. 1 is circuit structure block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Circuit structure of the present utility model as shown in Figure 1, comprises power supply, the time relay and occupant detection unit; Described occupant detection unit comprises several microswitches with normally closed contact, one of them microswitch is located at the bottom of assistant driver seat, all the other microswitches are equidistantly distributed in the bottom of back row seats, and for perception seat pressure, the normally closed contact of all microswitches is connected successively; Described power supply is connected with the coil of the time relay by occupant detection unit; The normally opened contact of the described time relay is connected with empty indicating lamp.
The time relay adopts the direct current time relay, and it can be combined and be designed to one with empty indicating lamp; Power acquisition alkaline battery; Occupant detection unit is for detecting the carrying situation in car: in the time having passenger to be sitting in assistant driver seat or back row seats, the button of being located at the microswitch of corresponding seat bottom can be depressed, the normally closed contact of microswitch can disconnect, now, occupant detection unit is equivalent to the switch of a disconnection, the power supply of time relay coil is cut off, and the normally opened contact of the time relay disconnects, and empty indicating lamp extinguishes; When assistant driver seat and back row seats are during all without passenger (zero load), the button of all microswitches is not all depressed, so the normally closed contact of each microswitch is all closed, now, occupant detection unit is equivalent to a closed switch, and timing can be connected and start to the power supply of time relay coil, in the time of the setting-up time (as 10 seconds) of relay time of arrival, the normally opened contact of the time relay can be closed, and empty indicating lamp can be lit.
Claims (3)
1. an empty indicating lamp controller, is characterized in that: comprise power supply, the time relay and occupant detection unit; Described occupant detection unit comprises several microswitches with normally closed contact, and one of them microswitch is located at the bottom of assistant driver seat, and all the other microswitches are equidistantly distributed in the bottom of back row seats, and the normally closed contact of all microswitches is connected successively; Described power supply is connected with the coil of the time relay by occupant detection unit; The normally opened contact of the described time relay is connected with empty indicating lamp.
2. a kind of empty indicating lamp controller according to claim 1, is characterized in that: the described time relay adopts the direct current time relay.
3. a kind of empty indicating lamp controller according to claim 1, is characterized in that: described power acquisition alkaline battery.
