SUMMERY OF THE UTILITY MODEL
Unexpected removal leads to dangerous chemicals to leak when solving above-mentioned industrial enterprise vehicle loading and unloading goods to cause the problem of explosion danger and casualties, the utility model provides a vehicle movement monitoring alarm system can whether real-time supervision vehicle is in quiescent condition, and set up on-the-spot audible-visual alarm, and output interlocking trigger signal, plays fine guarantee personal safety's effect.
The vehicle movement monitoring alarm system is used in cooperation with a vehicle, and is characterized by comprising: a reflection plate fixed to a side surface of the vehicle; the optical signal sensor is arranged right opposite to the reflecting plate, and is used for emitting a light source signal and receiving reflected light of the reflecting plate; the audible and visual alarm is used for giving out alarm sound; and the relay is connected with the optical signal sensor and the audible and visual alarm, and amplifies the optical signal into an electric signal when the optical signal received by the optical signal sensor meets the alarm condition.
The vehicle movement monitoring and alarming system is characterized in that a strong magnet is arranged on the back surface of the reflecting plate and used for being quickly fixed on a vehicle metal body.
The vehicle movement monitoring and alarming system is characterized in that output signals of the relay are divided into two paths.
The vehicle movement monitoring and alarming system is characterized in that one path of output signal of the relay is used for controlling the audible and visual alarm, and the other path of output signal is used for providing the PLC for safety interlocking.
The reflecting plate is attached to the side face of the vehicle, the light spot is located in the center of the reflecting plate, and the reflecting plate reflects the light signal back to the light signal sensor according to a reverse light path, so that a working circuit is formed. When the vehicle moves within a certain range, the light deviates from the range of the reflector plate, and then the light signal with enough intensity cannot be reflected to the light signal sensor, the output signal of the light signal sensor is amplified by the relay, one path of the output signal of the relay is used for controlling the work of the on-site audible and visual alarm, the other path of the output signal is used for providing the PLC for corresponding safety interlocking, the audible and visual alarm gives an alarm, and the safety interlocking device is started for interlocking.
The utility model discloses a beneficial effect is:
1) and (3) real-time monitoring and alarming: after the vehicle movement monitoring and alarming system is put into use, the vehicle movement condition can be monitored in real time, and when the vehicle movement distance exceeds a limit value, on-site sound and light alarming is timely carried out to prevent the connecting pipeline of the vehicle loading and unloading vehicle from being damaged or leaking.
2) And (4) overrun active safety protection: after the vehicle movement monitoring and alarming system is put into use, the vehicle movement condition can be monitored in real time, an interlocking protection signal is output when the vehicle movement distance exceeds a limit value, the material inlet and outlet valves are closed in an interlocking manner through a basic process control system in a factory or a field batch loading controller, and the material delivery pump is stopped in an interlocking manner, so that the liquid chemicals are prevented from leaking out in large quantity.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1, it is a schematic diagram of the vehicle movement monitoring and warning system in a normal state: the reflecting plate 2 is attached to the side face of the vehicle 5 through a strong magnet on the back face of the reflecting plate, the optical signal sensor 1 emits a light source signal to the reflecting plate 2 after being started, and the reflecting plate 2 reflects the light source to the receiving end of the optical signal sensor 1 to form a working loop.
As shown in fig. 2, it is a schematic diagram of the vehicle movement monitoring alarm system in an alarm state: after the vehicle 5 moves, the reflecting plate 2 leaves the effective range of the light source emitted by the optical signal sensor 1, reflected light cannot return to the receiving end of the optical signal sensor 1, the output signal of the optical signal sensor 1 is amplified by the relay 3, one path of output signal of the relay 3 is used for controlling the work of the on-site audible and visual alarm 4, one path of output signal is used for providing corresponding safety interlock for the PLC, the audible and visual alarm 4 starts to give out alarm sound, and meanwhile safety interlock is triggered.
As shown in fig. 3, is a schematic diagram of the electrical principle of the vehicle movement monitoring and alarming system: vehicle movement monitoring alarm system needs external 24VDC working power supply, under normal condition, light signal sensor 1 output signal is normally open contact (N.O), when the vehicle moved, reflecting plate 2 left the effective range of light signal sensor 1 transmitting light source, then the reverberation can't get back to light signal sensor 1's receiving terminal, normally open contact is closed, relay 3 is in the excitation state, light signal sensor 1 output signal is through the amplifying back of relay 3 this moment, relay 3 output signal all the way is used for the work of control scene audible-visual annunciator, output signal all the way is used for providing PLC and carries out corresponding safety interlocking.
As shown in fig. 4, a deviation corresponding curve of the vehicle movement monitoring alarm system shows a relationship between the distance between the vehicle 5 and the optical signal sensor 1 and the deviation alarm curve, and within a certain distance range, the smaller the deviation Y value, the shorter the detectable movement distance X, and the more sensitive the corresponding detection. (the kind of the reflecting plate is H85:80mmx80 mm; C110_2: phi =84 mm; H60: 60mmx40 mm; F2000: 100mmx100 mm; H160: 60mmx18 mm).
