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 core of the invention is to provide a vehicle safety alarm method and system, so as to realize the purpose of smoothly identifying that an alarm trigger object is in a vehicle in summer and further reminding a driver of paying attention to the alarm trigger object missing on the vehicle.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 shows a flowchart of a vehicle safety warning method provided by an embodiment of the present invention, where the method specifically includes the following steps:
step S100, detecting whether an alarm triggering object exists on a seat by using a seat sensor of a vehicle; and when the alarm triggering object is determined to be on the seat, the step S101 is carried out, otherwise, the step is returned to continuously detect whether the alarm triggering object is on the seat.
The execution main body of the method provided by the embodiment of the invention is a vehicle safety alarm system, the vehicle safety alarm system can be realized through a vehicle body controller, and in order to facilitate the technical scheme of the invention to be understood by the technical personnel in the field, the vehicle body controller is taken as the execution main body for explanation.
In specific implementation, referring to fig. 2, the vehicle body controller 201 is connected to the plurality of seat sensors 200 through wires, and is connected to the air conditioning control system 202 and the mobile data transmitting device 203 through a network bus. In order to avoid false alarm or frequent alarm, the vehicle body controller 201 starts the system when determining that the vehicle is in a locked state, and then judges whether an alarm triggering object exists on the seat by using the seat sensor 200. Alternatively, the system can be started when the driver does not operate the vehicle for a certain time and the temperature in the vehicle exceeds a preset threshold value, wherein the preset threshold value is a temperature value which is too hot or too cold for human or animals. The in-vehicle temperature can be obtained by the air conditioning control system 202. Of course, the two start conditions may be combined to set the system start condition, and are not limited to this.
The seat sensor 200 is a pressure-sensitive sensor, and specifically, may be a multi-way contact switch, where contacts of the sensor are uniformly distributed on a force-bearing surface of the seat, and a trigger signal is generated when the seat sensor 200 is subjected to a pressure from the outside. In conjunction with the actual scenario, the contacts on the seat sensor 200 are closed when there is an item in the seat, a passenger is seated, or a pet is lying down. When the seat sensor 200 detects a signal of contact, it sends a detection signal to the body controller 201.
And step S101, sending an alarm signal aiming at the alarm trigger object on the seat to a client of the driver so as to remind the driver that the object needing attention is in the vehicle.
Specifically, the body controller 201 may repeatedly send the warning signal to the client of the driver according to a preset period, and request the driver to perform an operation of confirmation or omission at the client, and may only release the warning and stop sending the warning signal to the client of the driver when receiving the feedback information sent by the driver through the client.
Further, referring to fig. 2, the vehicle body controller 201 sends an alarm signal to the backend server 204 through the mobile data sending device 203 in the vehicle, and the backend server 204 associates the obtained alarm signal with the mobile phone number of the driver, and then sends the alarm signal to the client 205 of the driver through the network and sends out an alarm prompt. The client 205 transmits the operation of the driver back to the vehicle body controller 201 according to the transmission path, and the vehicle body controller 201 stops the operation of the system, so as to save the electric energy loss of the vehicle.
In conclusion, the alarm triggering object is determined through pressure sensing, so that the condition that the detection result of the infrared temperature sensor is influenced by high temperature in summer is effectively avoided, and the aims of smoothly identifying the alarm triggering object in the vehicle in summer and reminding a driver of paying attention to the alarm triggering object missed on the vehicle are fulfilled.
Based on the technical solution disclosed in the above embodiment of the present invention, in this embodiment, a detailed description is given to the specific implementation process of the step S101, in which an alarm signal for an alarm trigger object on a seat is sent to the client 205 of the driver to remind the driver that an object needing attention is located in the vehicle, with reference to fig. 3, the specific implementation process specifically includes the following steps:
step S300, acquiring a detection signal of the seat sensor 200, and determining the change condition of the detection signal in a continuous preset time period;
s301, determining the object type of an alarm triggering object on the seat according to the change condition of the detection signal;
wherein, the object type of the alarm triggering object comprises static objects, moving people and/or pets.
Specifically, since the seat sensor 200 is pressed from the outside, the contact points thereof are turned on, and when the seat sensor 200 detects a signal of the contact points, a detection signal is sent to the body controller 201. Based on this, when the detection signal received by the vehicle body controller 201 is a persistent signal, the object type of the alarm triggering object is considered as a static article; when the detection signal is a change signal, determining that the object type of the alarm triggering object is a moving person and/or pet. It should be noted that the stationary object is not a stationary object in a strict sense, and includes a person or a pet who is stationary on the seat or does not move much (the contact of the seat sensor 200 cannot be made to contact and break back and forth); meanwhile, a moving person and/or pet generally refers to any living thing that can make and break the contact points of the seat sensor 200 to and from.
Step S302, sending an alarm signal corresponding to the object type of the alarm trigger object on the seat to the client 205 of the driver for the object type of the alarm trigger object on the seat.
Specifically, when the object type of the alarm triggering object on the seat is a static object, the driver is reminded of the static object needing attention in the vehicle in a text message mode; when the object type of the alarm triggering object on the seat is a moving person and/or pet, the driver is reminded of the moving person and/or pet needing attention in the vehicle in a voice mode.
For example, if the client 205 of the driver receives that the seat has an article missing, a simple message prompt is performed (for example, "you have an article missing on the vehicle") to request the driver to perform a confirmation or an ignore operation; if the client 205 receives a person or a pet in the seat, it performs a sound + vibration alarm (for example, "person or pet is locked in your vehicle and please go to process immediately to ensure safety"), and requests the driver to perform a confirmation or an ignore operation on the mobile phone, so as to release the alarm.
