Detailed description of the invention
Core of the present invention is to provide a kind of warning, and when car door is not locked, remind navigating mate to process in time, to ensure that in compartment, temperature stabilization is in allowed band, another core of the present invention is to provide a kind of van cooler with this warning.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in figs 1 to 6, the invention discloses a kind of warning of van cooler, comprise: the loop of warning device 101, compartment single pole double throw switch 103 and power supply 104 composition, wherein, the car door state mechanical linkage of compartment single pole double throw switch 103 and van cooler, and the not moved end of the car door of van cooler compartment single pole double throw switch 103 when being closed condition is connected with the first contact of moved end, when the car door of van cooler is open mode, the not moved end of compartment single pole double throw switch 103 is connected with the second contact of moved end; Warning device 101 is connected with the not moved end of the second contact of compartment single pole double throw switch 103.By increasing warning device 101, and set the circuit loop be connected with warning device 101, when car door is not closed, whole loop forms closed circuit, warning device 101 is worked, thus reminds navigating mate car door not close, can effectively avoid because car door does not close the quality of temperature fluctuations affect chilled products in the compartment caused, the oil consumption of refrigerating transport vehicle can also be reduced, economize energy.
Above-mentioned device can be connected formation loop, concrete, one end of warning device 101 all can be connected with two moved ends of compartment single pole double throw switch 103, the not moved end of compartment single pole double throw switch 103 is connected with power supply 104, and the other end of power supply 104 is connected with the other end of warning device 101.
In further embodiment, this warning also comprises the alarm button 102 be connected on loop, and the not moved end of this alarm button 102 is connected with warning device 101, and first of the moved end of warning device 101 is connected with the second contact of the moved end of compartment single pole double throw switch 103, the second point of alarm button 101 moved end is connected with the first contact of the moved end of compartment single pole double throw switch 103, and during this alarm button 102 of button, moved end is not connected with second point by first connected being switched to.By arranging alarm button 102, when there being people to be locked in compartment, the not moved end of compartment single pole double throw switch 103 is connected with the first contact of moved end, and the not moved end of alarm button 102 is connected with first, now loop is open circuit, by lock personnel by pressing alarm button 102 to make the not moved end of alarm button 102 by first to second point, thus it is electric to make loop obtain, warning device is reported to the police, people is had to be locked in compartment to remind navigating mate, personnel are succoured, prevents personal safety accident.
In preferred embodiment, this warning also comprises the motoring condition switch 105 be connected on loop, and when van cooler runs, the not moved end of motoring condition switch 105 is connected with the first point of connection of moved end; When van cooler is static, the not moved end of motoring condition switch 105 is connected with the second point of connection of moved end.Be connected with one end of gang switch 106 by second point of connection of the moved end of motoring condition switch 105 in the application, the first point of connection of the moved end of motoring condition switch 105 is connected with warning device 101.Wherein, gang switch 106 and compartment single-pole double throw (SPDT) 103 switch gearing, when car door is opened, gang switch 106 disconnects, and when car door is closed, gang switch 106 closes.Can detect the running state of van cooler by arranging motoring condition switch 105, and according to above-mentioned connection mode, to ensure when van cooler does not run, time namely static, opening car door warning device can not report to the police, to reduce energy dissipation.Arranging gang switch 106 object is: when vehicle stops, if open car door unloading, gang switch 106 disconnects, and warning device 101 can not obtain electric alarm; If car door is closed condition, gang switch 106 closes, and now have trapped personnel to push for emergency button 102 in compartment, warning device 101 can obtain electric alarm.
Further in embodiment, warning also comprises and being connected with above-mentioned motoring condition switch 105, for detecting the car speed instrument 107 of van cooler state of kinematic motion.Detected the speed of current van cooler by car speed instrument 107, and be running state or quiescence according to the velocity estimated detected, and control the motion of the not moved end travelling mode switch 105.By arranging car speed instrument 107, can the automation of implement device.When car speed instrument detects that van cooler speed is 0, motoring condition switch disconnects, and when car speed instrument detects that van cooler speed is not 0, motoring condition switch closes.
On the basis of technique scheme, one end of warning device 101 in the application is connected with the not moved end of alarm button 102, and the not moved end of compartment single pole double throw switch 103 is connected with power supply 104, the other end of power supply 104 is connected with the not moved end of motoring condition switch 105.This provides the complete connection mode of this warning, and this connection mode is simple.
According to the above-mentioned connection mode provided, the circuit theory being in different operating shape body is as follows:
As shown in Figure 1, for the normal condition in refrigerating transport vehicle traveling, now car speed instrument 107 detects that the speed of refrigerating transport vehicle is not 0, car speed instrument 107 makes motoring condition switch 105 be connected with the first point of connection (in figure, e holds), particularly, this car speed instrument 107 can be to link with motoring condition switch 105 and arranges, without personnel in compartment, alarm button 102 is not pressed, the not moved end of alarm button is connected with the first point (in figure, b holds), refrigerating transport vehicle car door is closed condition, compartment single pole double throw switch 103 is connected with the first contact (in figure, c holds), coordinated signals makes gang switch 106 connect, namely moved end is not held with g in figure and is connected.The loop of whole warning is off state, warning device 101 not electric, can not alerting signal be sent.
