Abstract
The utility model discloses a traffic accident collision alarm circuit, which comprises a singlechip U2, a wireless module U1 and a gyroscope chip U3, wherein the singlechip U2 is respectively connected with the wireless module U1 and the gyroscope chip U3 in a signal manner; the gyroscope chip U3 collects X, Y and Z-axis direction included angles and acceleration values, and the frequency of signals collected by the gyroscope chip U3 is 20-30 times/second. The alarm circuit of this structure can gather in real time and judge the collision condition of current device to judge whether report to the police through the severity of preset threshold judgement being bumped. The singlechip sends on-line handshake information to the management and control platform with the wireless module at regular intervals, thereby realizing real-time management and alarm.
Description
Technical Field
The utility model relates to a traffic accident alarming circuit, in particular to a collision traffic accident alarming circuit applied to road equipment such as guardrails, telegraph poles, traffic lights and the like.
Background
Because the topography of China is complex and changeable, the places where vehicles pass are on the cliff side, traffic accidents are easy to be caused, or accidents such as guardrail collapse and the like caused by geological disasters can not be timely saved, and larger casualties and property loss are caused. If the intelligent monitoring alarm device is arranged at the key point which is easy to cause traffic accidents, the occurrence of the accidents is found in time, and the alarm is given out early, so that the wounded is ensured to be rescued at the first time.
Disclosure of Invention
The utility model solves the technical problem that the accident-prone area is not found in time, and provides an alarm circuit capable of accurately positioning the accident-prone area and giving an alarm in time.
The technical scheme adopted by the utility model is as follows: the traffic accident collision alarm circuit comprises a singlechip U2, a wireless module U1 and a gyroscope chip U3, wherein the singlechip U2 is respectively connected with the wireless module U1 and the gyroscope chip U3 in a signal manner; the gyroscope chip U3 collects X, Y and Z-axis direction included angles and acceleration values, and the frequency of signals collected by the gyroscope chip U3 is 20-30 times/second.
As a further improvement of the utility model, pins CS, SCL and SDA of the gyroscope U3 are respectively connected with a power supply through resistors, the resistors are used as pull-up resistors to enhance driving signals, and the pins SDX and SCX of the gyroscope U3 are grounded. The structure ensures that the alarm circuit does not need to be connected with the ground of an external expansion sensor to prevent noise from interfering communication.
As a further improvement of the utility model, the wireless module U1 adopts an NB-IOT wireless module.
The utility model has the beneficial effects that: the alarm circuit of this structure can gather in real time and judge the collision condition of current device to judge whether report to the police through the severity of preset threshold judgement being bumped. The singlechip sends on-line handshake information to the management and control platform with the wireless module at regular intervals, thereby realizing real-time management and alarm.
Drawings
FIG. 1 is a schematic diagram of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in the figure, the traffic accident collision alarm circuit comprises a singlechip U2, a wireless module U1 and a gyroscope chip U3, wherein the singlechip U2 is respectively connected with the wireless module U1 and the gyroscope chip U3 through signals; the gyroscope chip U3 collects X, Y and Z-axis direction included angles and acceleration values, the frequency of signals collected by the gyroscope chip U3 is 20-30 times/second, collected information is transmitted to the singlechip U2, the singlechip U2 analyzes the current state in real time, and when the gyroscope chip is impacted, the values can be changed suddenly.
In embodiment 1, a safety barrier is provided in an accident-prone area, and an alarm circuit of the structure is assembled in the barrier. The GPS coordinates of the accident-prone section are configured to the singlechip, the singlechip receives the guardrail state information sent by the gyroscope chip in real time, and meanwhile, the singlechip sends on-line handshake information to the management and control platform through the NB-IoT wireless module at regular intervals to indicate that the place is currently in a safe state. When the guardrail is collided and a traffic accident occurs, the gyroscope chip immediately transmits information to the singlechip, and the singlechip judges whether the amplitude exceeds a preset threshold value, and if the amplitude exceeds the threshold value category, the gyroscope chip judges that an alarm is required. If alarm is needed, the address of the unit, namely the GPS information and the bumped data, are packaged and sent to the management and control platform through the NB-IoT wireless module, and the management and control platform sends alarm information to the on-duty personnel, so that timely alarm is guaranteed.
The alarm circuit of the structure can be applied to traffic accident multiple places, and can also be applied to geological disaster multiple places, such as mountain landslide easy places, mud-rock flow easy places and the like. And adjusting the different set thresholds to adapt to each application scene.
It should be understood by those skilled in the art that the protection scheme of the present utility model is not limited to the above embodiments, and various arrangements and modifications can be made on the basis of the above embodiments, and various modifications of the present utility model fall within the protection scope of the present utility model without departing from the spirit of the present utility model.
