Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a charging loop detection system, which is applied to rail transit vehicles and comprises the following components in part by weight as shown in figure 2:
and the ground charging module 11 is used for detecting whether a conduction loop which is conducted between the charging cabinet and the vehicle-mounted charging socket works normally or not, and if the conduction loop works normally, starting a high-voltage charging program of the charging cabinet.
Specifically, the ground charging module 11 determines whether the conducting loop works normally by detecting the conducting condition and/or the voltage range of the conducting loop, for example, the ground charging module 11 provides a voltage to detect whether the conducting loop is conducted, if the conducting loop works normally, and if the conducting loop does not work normally, the conducting loop works abnormally; the ground charging module 11 may further detect whether the circuit voltage is within a preset range, if so, it indicates that the conduction loop is working normally, and if not, it indicates that the conduction loop is working abnormally.
The conduction loop can be a closed loop formed by connecting the charging cabinet in the warehouse, the charging cable and the vehicle-mounted charging socket in series; the ground charging module 11 may provide a voltage of 110V as the turn-on voltage, and at this time, the preset voltage range may be 77V to 135V.
The ground charging module 11 may be disposed in the charging cabinet, so as to drive a high-voltage charging program of the charging cabinet.
It can be understood that, when the ground charging module 11 detects that the charging circuit works abnormally, the high-voltage charging program of the charging cabinet is not started, so as to avoid that the user cannot detect the actual charging failure because the charging program is still started when the charging cabinet has a fault such as poor contact in the charging circuit, thereby ensuring the reliability and timeliness of the charging operation.
And the vehicle-mounted charging module 12 is used for detecting whether a conduction loop for realizing conduction between the charging cabinet and the vehicle-mounted charging socket works normally or not, and if the conduction loop works normally, starting a high-voltage charging program of the vehicle-mounted charging socket.
Specifically, the vehicle-mounted charging module 12, like the ground charging module 11, may determine whether the conduction loop is working normally by detecting the conduction condition and/or the voltage range of the conduction loop, and after obtaining the detection result that the conduction loop is working normally, the vehicle-mounted charging module 12 starts the high-voltage charging program of the vehicle-mounted charging socket to prepare for charging the charging cabinet and the vehicle-mounted charging socket.
The vehicle-mounted charging module 12 may be disposed in a vehicle to control the vehicle-mounted charging socket to start a high-voltage charging program of the vehicle-mounted charging socket.
It can be understood that, when it is detected that the charging circuit works abnormally, the vehicle-mounted charging module 12 does not start the high-voltage charging program of the vehicle-mounted charging socket, so as to avoid the situation that the user cannot detect the actual charging failure because the charging program is still started when the vehicle-mounted charging socket has a fault such as poor contact in the charging circuit, and thus, the reliability and timeliness of the charging operation are ensured.
It should be noted that the vehicle-mounted charging socket enters the charging state only when the ground charging module 11 and the vehicle-mounted charging module 12 respectively start the corresponding high-voltage charging programs.
The invention uses the ground charging module 11 to detect whether the conducting loop between the charging cabinet and the vehicle charging socket works normally, if the normal detection result is obtained, the ground charging module 11 starts the high-voltage charging program of the charging cabinet, then uses the vehicle charging module 12 to detect whether the conducting loop between the charging cabinet and the vehicle charging socket works normally, if the normal detection result is obtained, the vehicle charging module 12 starts the high-voltage charging program of the vehicle battery, when the vehicle charging module 12 and the ground charging module 11 start the respective high-voltage charging program at the same time, the charging function of the charging cabinet to the vehicle battery is realized, if the vehicle charging module 12 and/or the ground charging module 11 detects that the conducting loop between the charging cabinet and the vehicle charging socket works abnormally, the corresponding module does not start the high-voltage charging program, therefore, the working personnel can know that the charging between the vehicle-mounted battery and the charging cabinet is failed, and therefore the timeliness and the reliability under the charging mode are guaranteed.
The embodiment of the invention discloses a specific charging loop detection system, and compared with the previous embodiment, the technical scheme is further explained and optimized in the embodiment. Specifically, the method comprises the following steps:
in practical application, work is unusual when detecting the charging circuit, and when unable realization charges the function of charging between cabinet and the on-vehicle socket that charges, for reminding as early as possible the staff to overhaul work such as, for this reason, charging circuit detecting system can also include: the charging cabinet alarm module and/or the vehicle-mounted alarm module; wherein,
and the charging cabinet alarm module is used for alarming when the ground charging module detects that the work of a conduction loop which is conducted between the charging cabinet and the vehicle-mounted charging socket is abnormal.
Specifically, cabinet alarm module charges can adopt bee calling organ to report to the police, or adopt the warning light to report to the police, certainly also can combine, can also send alarm information to staff's cell-phone, or show fault information through the display screen, or adopt other warning modes that can in time remind the staff to overhaul again, do not do the restriction here.
And the vehicle-mounted alarm module is used for alarming when the vehicle-mounted charging module detects that the work of a conduction loop which is conducted between the charging cabinet and the vehicle-mounted charging socket is abnormal.
Specifically, the vehicle-mounted alarm module can adopt a buzzer to give an alarm, or adopt a prompt lamp to give an alarm, and can also be combined with the buzzer, and can also send alarm information to a mobile phone of a worker, or display fault information through a display screen, or adopt other alarm modes which can prompt the worker to overhaul in time, and the alarm mode is not limited here.
In the embodiment of the invention, the ground charging module can be specifically used for detecting whether the first detection loop works normally or not, and if the first detection loop works normally, starting a high-voltage charging program of the charging cabinet; the vehicle-mounted charging module can be specifically used for detecting whether the second detection loop works normally or not, and starting a high-voltage charging program of the vehicle-mounted battery if the second detection loop works normally; the first detection loop and the second detection loop are respectively a conduction loop for realizing conduction between the charging cabinet and the vehicle-mounted charging socket.
In practical application, when the charging cabinet needs to charge the vehicle-mounted battery, high-voltage charging is needed, therefore, a high-voltage-resistant charging loop is needed, if high voltage is still used as detection voltage during detection, energy waste is caused, and because the high-voltage charging programs of the charging cabinet and the vehicle-mounted charging socket are respectively and independently operated, the ground charging module and the vehicle-mounted charging module need to respectively obtain detection results so as to realize that the charging cabinet and the vehicle-mounted charging socket both start the high-voltage charging program and complete the charging process.
For example, the interface of the detection circuit and the interface of the charging circuit are arranged side by side to ensure that when the interface of the detection circuit is tightly connected with the charging cabinet and the vehicle-mounted charging socket interface respectively, the interface of the charging circuit is also tightly connected with the charging cabinet and the vehicle-mounted charging socket interface, so that the charging module and the vehicle-mounted charging module can judge whether the interface of the charging circuit is tightly connected with the charging cabinet and the vehicle-mounted charging socket interface respectively by detecting whether the first detection circuit works normally.
Specifically, the ground charging module judges whether to start the high-voltage charging program of the charging cabinet according to the detection result by detecting whether the first detection circuit works normally, the vehicle-mounted charging module judges whether to start the high-voltage charging program of the vehicle-mounted charging socket according to the detection result by detecting whether the second detection circuit works normally, and the ground charging module and the vehicle-mounted charging module start respective corresponding high-voltage charging programs, so that the vehicle-mounted charging socket enters a charging state.
Referring to fig. 3, the first detection loop may be connected such that the first connection point a1 of the charging cabinet is connected to the first connection point b11 of the first cable of the charging cable, the second connection point b12 of the first cable of the charging cable is connected to the first connection point c1 of the vehicle-mounted charging socket, the first connection point c1 of the vehicle-mounted charging socket is connected to the second connection point c2 of the vehicle-mounted charging socket, the second connection point c2 of the vehicle-mounted charging socket is connected to the second connection point b22 of the second cable of the charging cable, the first connection point b21 of the second cable of the charging cable is connected to the second connection point a2 of the charging cabinet, and the first connection point a1 and the second connection point a2 of the charging cabinet are respectively connected to the ground charging module; the second detection loop may be connected in series with the vehicle-mounted charging socket third connection point c3, the charging cable third connection point b32, the third cable first connection point b31, the charging cabinet third connection point a3, the charging cabinet fourth connection point a4, the charging cable fourth connection point b41, the fourth cable second connection point b42 and the vehicle-mounted charging socket fourth connection point c4, and the vehicle-mounted charging socket third connection point c3 and the vehicle-mounted charging socket fourth connection point c4 are connected with the vehicle-mounted charging module.
Furthermore, in the embodiment of the present invention, the ground charging module may be further specifically configured to detect whether the detection circuit is working normally; the vehicle-mounted charging module is specifically used for detecting whether the detection loop works normally; wherein, the detection return circuit is the switch-on return circuit between cabinet and the on-vehicle socket that charges.
It can be understood that, by designing a detection loop, the ground charging module and the vehicle-mounted charging module jointly use the detection loop to obtain a test result, so as to respectively start the high-voltage charging programs and complete the charging program of the vehicle-mounted charging socket, thereby further simplifying the system structure.
Correspondingly, the embodiment of the invention also discloses a charging loop detection method, which is applied to rail transit vehicles, and as shown in fig. 4, the method comprises the following steps:
