Example Embodiment

[0033] The present invention will be further described below in conjunction with specific embodiments.
[0034] Such as figure 1 with figure 2 Shown is a guardrail cleaning vehicle attitude prompt control system, including a first ultrasonic sensor 1, a second ultrasonic sensor 2, a controller 3, a buzzer 4, a left front indicator light 5, a left rear indicator light 6, and a right front indicator light 7. The right rear indicator light 8. It is characterized in that the AI ​​input port of the controller 3 is respectively connected to the first ultrasonic sensor 1 and the second ultrasonic sensor 2, and the DO output port of the controller 3 is respectively connected to the buzzer 4, the left front indicator light 5, and the left rear indicator light 6, respectively. The right front indicator light 7 and the right rear indicator light 8 are connected.
[0035] The AI ​​input port of the controller is used to receive signals from the first ultrasonic sensor and the second ultrasonic sensor to detect the distance between the front and rear of the vehicle and the guardrail, and the DO output port of the controller is used to output control signals to the buzzer , Left front indicator, left rear indicator, right front indicator, right rear indicator.
[0036] The working process of the present invention is as follows:
[0037] Before the show: Set the maximum and minimum distances from the guardrail and the maximum allowable difference between the front and rear of the vehicle body and the guardrail. The connection of the four indicator lights in the cab indicates the body attitude. When the left side line of the vehicle body is outside the range of the vehicle allowed to be displayed, the indicator light representing the corresponding position is always on; when the left side line of the vehicle body is in the allowed vehicle display range If the distance between the front and rear of the vehicle body and the guardrail exceeds the allowable range, the indicator lamp of the corresponding position will flash; when the left side line of the vehicle body is within the range of the allowable display, the difference between the distance between the front and rear of the vehicle body and the guardrail is within the allowable range. When it is within the allowable range (that is, the vehicle meets the conditions of the show), all four indicator lights are off.
[0038] During cleaning and driving: detect the distance between the front and rear of the body and the guardrail. When the difference between the front and rear of the body and the guardrail exceeds the allowable range (the body deviates from a certain range), the indicator lamp representing the corresponding position flashes and the buzzer sends out an alarm signal. , Prompt the driver to make the corresponding steering action to make the body back to the center.

[0042] (2) Set the minimum Lmin and maximum Lmax of the vehicle’s distance from the guardrail when the vehicle is allowed to be exhibited. Set the distance L1′ from the left front edge of the vehicle to the guardrail when the vehicle is within the allowable display range. The maximum difference D of the distance L1″ between the side line and the guardrail.
[0043] (3) When the distance L1′ between the left front edge of the guardrail cleaning vehicle and the guardrail and the distance L1″ between the left rear edge and the guardrail are both greater than the maximum allowable display car Lmax, such as image 3 As shown in (a), the left front indicator is off, the left rear indicator is off, the right front indicator is always on, and the right rear indicator is always on.
[0044] (4) When the distance L1′ from the left front edge of the guardrail cleaning vehicle to the guardrail is within the allowable range of exhibition vehicles, and the distance L1″ from the left rear edge of the guardrail cleaning vehicle to the guardrail is greater than the maximum allowable exhibition vehicle Lmax, such as image 3 As shown in (b), the left front indicator light is flashing, the left rear indicator light is off, the right front indicator light is off, and the right rear indicator light is always on.
[0045] (5) When the distance L1′ from the left front edge of the guardrail cleaning vehicle to the guardrail is less than the minimum allowable display car Lmin, and the distance L1″ from the left rear edge of the guardrail cleaning vehicle to the guardrail is greater than the maximum allowable display car Lmax, such as image 3 As shown in (c), the left front indicator light is always on, the left rear indicator light is off, the right front indicator light is off, and the right rear indicator light is always on.
[0046] (6) When the distance L1′ between the left front edge of the guardrail cleaning vehicle and the guardrail is greater than the maximum allowable display car Lmax, and the distance L1″ from the left rear edge of the guardrail cleaning vehicle to the guardrail is within the allowable display range, such as image 3 As shown in (d), the left front indicator is off, the left rear indicator is flashing, the right front indicator is always on, and the right rear indicator is off.
[0047] (7) When the distance L1′ from the left front edge of the guardrail cleaning vehicle to the guardrail is greater than the maximum allowable display car Lmax, and the distance L1″ from the left rear edge of the guardrail cleaning vehicle to the guardrail is less than the minimum allowable display car Lmin, such as image 3 As shown in (e), the left front indicator is off, the left rear indicator is always on, the right front indicator is always on, and the right rear indicator is off.
[0048] (8) When the distance L1′ from the left front edge of the guardrail cleaning vehicle to the guardrail and the distance L1″ from the left rear edge to the guardrail are both within the allowable display range, but the distance between the left front edge of the guardrail cleaning vehicle and the guardrail The difference between the distance L1′ and the distance L1″ between the left rear edge and the guardrail is greater than the maximum difference D, and the distance L1′ from the left front edge of the guardrail cleaning vehicle to the guardrail is greater than the distance L1 from the left rear edge to the guardrail "When image 3 As shown in (f), the left front indicator light is off, the left rear indicator light is flashing, the right front indicator light is flashing, and the right rear indicator light is off.
