When the PLC controller determines that the area around the high temperature sensor 46 is a high water temperature but determines that the area around the low temperature sensor 45 is a non-low water temperature, the PLC controller compares the detection information of the low temperature sensor with the detection information of the high temperature sensor.
If the difference between the detection information of the low-temperature sensor and the detection information of the high-temperature sensor is not less than the set value, after the PLC determines that the periphery of the high-temperature sensor 45 is at a high water temperature, the PLC sequentially gives instructions to a third valve body 44, a fourth valve body 47 and a hot water circulating pump 48, the third valve body 44 and the fourth valve body 47 are opened first, then the hot water circulating pump 48 starts to work, hot water flows into the heat exchange energy storage water storage tank 41 from a water inlet pipe of the heat exchange energy storage water storage tank 41, after the set working time is reached, the PLC sequentially gives instructions to the hot water circulating pump 48, the third valve body 44 and the fourth valve body 47, the hot water circulating pump 48 stops working first, and then the third valve body 44 and the fourth valve body 47 are closed; the hot water flow in the solar heat collector 42 by the solar energy is led into the heat exchange and energy storage water storage tank 41, so that the utilization rate of the heat energy is improved, and the phenomenon that the water temperature in the solar heat collector 42 by the solar energy is too high and the equipment is damaged is prevented.
The working principle of the efficient heat dissipation unit 5 is as follows:
starting the efficient heat dissipation unit 5 in the winter period:
the PLC controller has a cycle timing function. When the PLC controller determines that the time is within a set time period of a winter period (i.e., a set month), the PLC controller sequentially instructs the fifth valve 521 and the circulating water pump 21 to be reached, the fifth valve 521 is opened first, then the circulating water pump 21 starts to operate, hot water flows from the hot water main pipe 1 into the efficient heat dissipation group, and heat is dissipated to passengers waiting in the bus stop 92 through the efficient heat dissipation group;
when the PLC controller determines that the time is not within the set time period of the winter period (i.e., the set month) or determines that the time enters the summer period (i.e., the set month), the PLC controller sequentially instructs the fifth valve 521 and the circulating water pump 21 to stop working, and then the fifth valve 521 is closed, so that the high-efficiency heat dissipation unit 5 is deactivated.
Identification of the vehicle 93:
when a vehicle 93 enters a stop section behind a bus stop 92, infrared rays reflected by the infrared ray sensors after being shielded by the vehicle 93 are received by the infrared ray sensors, the distance between the vehicle 93 and the road surface of a road 91 is measured through the time when the infrared ray sensors receive reflected light, the measured distance information is transmitted to the PLC, no less than four pieces of distance information with adjacent positions are simultaneously transmitted to the PLC, the PLC judges that the distance information is effective after the distance information is stably output for 0.3s to 0.8s, and at the moment, the vehicle 93 stops in front of the bus stop 92; the PLC controller obtains the average distance between the vehicle 93 and the road surface of the road 91 after calculation, wherein the distance information smaller than 5cm does not take the original data for calculating the average distance into account, and the PLC controller judges that the vehicle 93 is the target vehicle when the average distance is higher than 22 cm; issuing a first instruction to the corresponding tail gas treatment units 7, namely the tail gas treatment units 7 corresponding to the infrared sensors which are not shielded and are close to the tail of the bus, and starting to work the corresponding tail gas treatment units 7; after the first instruction is given for 1s to 5s, the corresponding tail gas processing unit 7 receives the instruction to stop working;
after the PLC controller issues a first instruction, when the effective distance information is eliminated from a stable output state, the PLC controller judges that the vehicle 93 starts, the PLC controller issues a second instruction to the corresponding tail gas treatment unit 7, the corresponding tail gas treatment unit 7 starts to work, and the corresponding tail gas treatment unit 7 stops working after issuing the second instruction for 1s to 5 s.
The working principle of the tail gas treatment of the vehicle 93 is as follows:

the sewage flows into the small-diameter pipe 82 through the sewage outlet 81 and is stored at the bottom of the large-diameter cylinder 83, and when the height of the sewage level in the large-diameter cylinder 83 is higher than the lower end surface of the small-diameter pipe 82, the water layer isolates the large-diameter cylinder 83 and the sewage pipe 85 from the area outside the small-diameter pipe 82, so that the odor in the sewage pipe 85 can be prevented from diffusing to the area outside the small-diameter pipe 82;
the water level sensing member 86 detects the sewage in the large-diameter cylinder 83 and transmits information to the PLC in real time; when the PLC receives the no-water information sent by the water level sensing piece 86, namely the height of the sewage level in the large-diameter cylinder 83 is lower than the height of the water level sensing piece 86, the PLC judges that the sewage discharging and deodorizing unit 8 is lack of water, the water reaches the second valve body 84 under the instruction, the second valve body 84 is opened, and the cold water flows into the sewage discharging and water inlet pipe 87 from the cold water main pipe 2 through the second valve body 84 to supplement the water in the large-diameter cylinder 83; when the water level sensor 86 is over the height, the PLC controller receives the detection information sent by the water level sensor 86 and then sends a closing instruction to the second valve body 84, so that the water replenishing to the pollution discharge and deodorization unit 8 is completed, and the pollution discharge and deodorization unit 8 has the deodorization function again.
Supplementing water in the heat exchange and energy storage water storage tank:
the cable float switch 414 transmits the water level information to the PLC controller in real time, and when the PLC controller determines that the received information is lower than the lowest set value, the PLC controller sequentially sends instructions to the water replenishing valve 22 and the circulating water pump 21, the water replenishing valve 22 is opened first, then the circulating water pump 21 starts to work, and water flows into the cold water main pipe 2 from the municipal water replenishing pipe 23 and finally enters the heat exchange energy storage water tank 41; when the information received by the PLC is higher than the highest set value, the PLC sends instructions to the circulating water pump 21 and the water replenishing valve 22 in sequence, the circulating water pump 21 stops working firstly, and then the water replenishing valve 22 is closed, so that the water in the heat exchange and energy storage water storage tank is replenished.
