Even.Wherein, linked switch 106 and 103 switch gearing of compartment single-pole double throw, linked switch 106 disconnects when car door is opened, compartment
Linked switch 106 is closed when door is closed.By setting the operating statuses of 105 detectable refrigerator cars of transport condition switch, and according to
Above-mentioned connection mode, to ensure when refrigerator car is not run, i.e., when static, opening compartment door alarm device will not alarm, with
Reduce energy waste.Set 106 purpose of linked switch be：When vehicle stops, if opening car door unloading, linked switch 106
It disconnects, warning device 101 will not obtain electric alarm；If car door is in off state, linked switch 106 is closed, and is had at this time in compartment
Trapped person presses alarm button 102, and warning device 101 can obtain electric alarm.
In further embodiment, alarm system is further included to be connected with above-mentioned transport condition switch 105, cold for detecting
Hide the car speed instrument 107 of vehicle motion state.The speed of current refrigerator car is detected by car speed instrument 107, and according to detection
Velocity estimated be operating status or stationary state, and control the movement of the non-moving end of transport condition switch 105.Pass through setting
Car speed instrument 107 is, it can be achieved that the automation of device.When it is 0 that car speed instrument, which detects refrigeration vehicle speed, transport condition is opened
Shut-off is opened, and when car speed instrument detects that it is not 0 to refrigerate vehicle speed, transport condition switch is closed.
Based on the above technical solutions, one end of the warning device 101 in the application and alarm button 102 is motionless
End is connected, and the non-moving end of compartment single-pole double-throw switch (SPDT) 103 is connected with power supply 104, and the other end and the transport condition of power supply 104 are opened
The non-moving end of pass 105 is connected.This provides the complete connection mode of the alarm system, and the connection mode is simple.
According to the connection mode of above-mentioned offer, the circuit theory in different operating shape body is as follows：
As shown in Figure 1, the normal condition in being travelled for refrigerating transport vehicle, car speed instrument 107, which detects, at this time refrigerates fortune
The speed of defeated vehicle is not 0, and car speed instrument 107 makes transport condition switch 105 be connected with the first tie point (e ends in figure), specifically
Ground, the car speed instrument 107 and transport condition switch 105 can be that linkage is set, without personnel in compartment, alarm button 102 not by
It presses, the non-moving end of alarm button is connected with first point (b ends in figure), and refrigerating transport vehicle car door is in off state, compartment list
Double-pole double throw switch 103 is connected with the first contact (c ends in figure), and coordinated signals connect linked switch 106, i.e., in non-moving end and figure
G ends connect.The circuit of entire alarm system is off-state, warning device 101 not it is electric, alarm signal will not be sent.
As shown in Fig. 2, being not turned off state for car door in refrigerating transport vehicle traveling, car speed instrument 107 detects at this time
The speed of refrigerating transport vehicle is not 0, and coordinated signals make transport condition switch 105 be connected, compartment with the first tie point (e ends in figure)
Interior no personnel, alarm button 102 are not pressed, and therefore, first point (b ends in figure) of the non-moving end moved end of alarm button 102 is even
It connects.Since refrigerating transport vehicle car door does not close so that compartment single-pole double-throw switch (SPDT) 103 is to be not turned off state, compartment single-pole double throw
The non-moving end of switch 103 and the second contact (d ends in figure) of moved end connect, and coordinated signals disconnect linked switch 106, i.e., motionless
End is separated with g ends.The circuit of entire alarm system is connected state, and warning device 101 must be electric, sends alarm signal.
As shown in figure 3, to press alarm button state by lock personnel in compartment in refrigerating transport vehicle traveling, vehicle is fast at this time
Degree instrument 107 detects that the speed of refrigerating transport vehicle is not 0, and coordinated signals make transport condition switch 105 and the first tie point (in figure
E ends) it connects, have in compartment by lock personnel, when alarm button 102 is pressed, the non-moving end of alarm button 102 and the second of moved end
Point (a ends in figure) connects, and refrigerating transport vehicle car door is in off state, the non-moving end of compartment single-pole double-throw switch (SPDT) 103 and first
Contact (c ends in figure) connects, and coordinated signals connect linked switch 106, i.e., non-moving end is connected with g ends.Entire alarm system
Circuit is connected state, and warning device 101 must be electric, sends alarm signal.
As shown in figure 4, normal condition when stopping for refrigerating transport vehicle, car speed instrument 107, which detects, at this time refrigerates fortune
The speed of defeated vehicle is 0, and coordinated signals connect the non-moving end of transport condition switch 105 and the second tie point (f ends in figure) of moved end
It connects, is not pressed without personnel, alarm button 102 in compartment, therefore, first point (b ends in figure) connection of non-moving end and moved end is cold
It hides transport vehicle car door to be in off state, the non-moving end of compartment single-pole double-throw switch (SPDT) 103 and the first contact (c ends in figure) of moved end
Connection, coordinated signals make linked switch 106 be connected with g ends.The circuit of entire alarm system is off-state, warning device 101
Not it is electric, alarm signal will not be sent.
As shown in figure 5, pressing alarm button state by lock personnel in compartment when stopping for refrigerating transport vehicle, vehicle is fast at this time
Degree instrument 107 detects the speed of refrigerating transport vehicle as 0, coordinated signals make transport condition switch 105 non-moving end and moved end the
Two tie points (f ends in figure) connect, and have in compartment by lock personnel, when alarm button 102 is pressed, alarm button 102 it is motionless
End is connected with the second point (a ends in figure) of moved end, and refrigerating transport vehicle car door is in off state, compartment single-pole double-throw switch (SPDT) 103
Non-moving end and the first contact (c ends in figure) of moved end connect, coordinated signals make linked switch 106 be connected with g ends.Entire alarm
The circuit of system is connected state, and warning device 101 must be electric, sends alarm signal.
It carries out unloading loading state as shown in fig. 6, opening car door when for refrigerating transport vehicle stopping, at this time car speed instrument
107 detect the speed of refrigerating transport vehicle as 0, and coordinated signals connect the non-moving end of transport condition switch 105 and the second of moved end
Contact (f ends in figure) connects, and alarm button 102 is not pressed in compartment, therefore the of the non-moving end of alarm button 102 and moved end
A bit (b ends in figure) connection, refrigerating transport vehicle car door to be not turned off state, the non-moving end of compartment single-pole double-throw switch (SPDT) 103 with
The second contact (d ends in figure) connection of moved end, coordinated signals make linked switch 106 be separated with g ends.The circuit of entire alarm system
For off-state, warning device 101 not it is electric, alarm signal will not be sent.
In order to further optimize the technical solution of the application, warning device 101 can be arranged to light crossing-signal or for sound
Sound alarm can also be arranged to the alarm 101 with light alarm and audible alarm simultaneously.It can root for the sound of light crossing-signal
It is set according to actual needs, such as may be set to red.The sound that voice guard may be configured as buzzing may be alternatively provided as it
His sound.
For the ease of reminding driver that warning device 101 can be mounted in driver's cabin, to facilitate driver can
The situation of refrigerator car is learnt at any time.Alarm button 102 is mounted in compartment.
In addition, present invention also provides a kind of refrigerator car, which has the alarm system disclosed in above-described embodiment,
Therefore, the refrigerator car with the alarm system is also with above-mentioned all technique effects, and this is no longer going to repeat them.
