Description

Technical Field

[0001] The present invention relates to the technical field of ETC devices, and particularly to a protective chassis for an ETC control terminal installed outdoors. Background Art

[0002] The ETC control terminal is the core device in the highway electronic toll collection system (ETC), mainly responsible for functions such as vehicle automatic identification, rapid toll calculation, data transmission, and lane device control.

[0003] Existing ETC control terminal devices are generally directly installed in the outdoor open environment through a protective chassis, and are exposed to harsh climate conditions such as high temperature, high humidity, condensation, and dust for a long time.

[0004] Traditional protective chassis mostly adopt passive heat dissipation (such as ventilation holes) or simple heating and dehumidification devices. However, in summer, the internal temperature of the device can reach above 70°C. Traditional heat dissipation only relies on the cooling fan to achieve air convection, and the cooling efficiency is insufficient. Furthermore, if the water-cooling method is used, the use and maintenance costs need to be greatly increased. If the simple spraying method is used for cooling, the humidity inside the chassis may be greatly reduced, which may easily affect the normal use of the internal components of the ETC control terminal. Therefore, this application proposes a protective chassis for an ETC control terminal installed outdoors. Summary of the Invention

[0040] The present invention discloses an ETC control terminal protection chassis for outdoor installation, and its beneficial effects are as follows:

[0041] 1. For the ETC control terminal protection chassis for outdoor installation, through the design of the inner and outer boxes of the outer box and the inner box, the ETC device is directly installed in the inner box, the outer box forms an isolation layer, and the heat dissipation cavity between the two serves as a heat exchange channel. Physical isolation reduces external interference. The directional airflow in the heat dissipation cavity improves the heat dissipation efficiency through spraying and moisture discharge. Moreover, the processor controls the condensation unit, the spraying unit, and the dehumidification unit to work according to the temperature and humidity detected by the temperature and humidity sensors. When the temperature exceeds the standard, spraying for cooling and dehumidification start. When the humidity exceeds the standard, moisture discharge is enhanced and spraying is weakened. If the humidity does not recover after three times, an alarm is given and the machine stops.

[0042] 2. The outdoor-mounted etc control terminal protection chassis generates condensed water using a condensation unit, stores the condensed water in a water storage tank, and uses a temperature and humidity sensor to detect the temperature and humidity inside the inner box, and checks whether the temperature inside the inner box is within the threshold value. If the temperature exceeds the upper threshold, the spraying unit is started, and the condensed water in the water storage tank is used to spray and cool in the heat dissipation cavity between the outer box and the inner box, and the dehumidification unit is turned on for dehumidification, and the hot and humid air evaporated by the spray due to high temperature is discharged outwards. It also checks whether the humidity inside the inner box is within the threshold value. If the humidity exceeds the upper threshold, the power of the dehumidification unit is increased to accelerate the discharge of the hot and humid air, and the intensity of the spraying unit is reduced.

[0043] 3. In the outdoor-mounted etc control terminal protection chassis, a liquid level sensor connected to the processor is installed inside the water storage tank. Using the liquid level sensor, when the liquid level sensor detects the condensed water level in the water storage tank and sends the data to the processor, when the liquid level in the water storage tank is too low, the power of the condensation unit is increased to improve the condensation speed, and when the liquid level in the water storage tank is too high, the condensation work of the condensation unit is suspended.

[0044] 4. In the outdoor-mounted etc control terminal protection chassis, with the provided condensation unit, the hot end of the thermoelectric cooler is actively cooled through heat dissipation fins and a cooling fan, and the cold end of the thermoelectric cooler generates condensed water through a microchannel radiator. Then, the condensed water drops into the water storage tank under the action of gravity. At the same time, V-shaped grooves that divide the aluminum plate into multiple channels are used to increase the contact area, forming a microchannel structure to improve the condensation efficiency.
