The inclination angle sensor 2 senses the inclination angle of the highway indicating board in the vertical direction and sends inclination angle data to the edge calculating unit 1, and the edge calculating unit 1 processes the data and obtains a processing structure. If the expressway sign plate is obviously inclined, and the inclination threatens the driving safety of the coming and going vehicles, the coming and going vehicles are warned through the road test unit 3, and the technical effect of facilitating the drivers of the coming and going vehicles to judge risks in time is achieved.
The edge computing unit only has a data processing function, and a person receiving and interpreting data is not beside the highway sign but in a corresponding command center, after the inclined data processing is completed, in order to solve the problem of how to send out data information on the intelligent detection terminal 10 and to timely warn drivers of vehicles coming and going, as shown in fig. 3, the intelligent detection terminal 10 provided by embodiment 2 of the invention further comprises a communication unit 4 for sending data; the communication unit 4 is in data communication connection with the edge calculation unit 1.

In embodiment 2 of the present invention, a 4G or 5G technical scheme may be selected for data transmission, and a wired communication scheme, for example, an optical fiber may be selected in addition to a wireless scheme.
Highway signs are known to be made of alloys, as well as illuminated signs. The luminous sign has more light emitting module than ordinary sign on, and light emitting module includes LED and relevant circuit etc.. These light emitting modules also have a certain probability of failure, such as aging of electronic devices, or infiltration of rainwater. In the prior art, most of the methods are to detect whether a light-emitting module of a highway indicator board has a fault in a manual inspection mode, so that the highway is required to employ more operation and maintenance personnel, and the efficiency is low.

In embodiment 2 of the present invention, a photovoltaic panel on a solar module absorbs light energy of the sun in the daytime, a part of the light energy is converted into electric energy to power the intelligent detection terminal 10, and the other part of the light energy is stored in a battery in the form of chemical energy, so that the power can be supplied to an inclination warning system for a highway sign in rainy days or at night. If the solar module is not used, wires are additionally pulled out from a power distribution room near the highway indicating board, pipelines are dug underground, and the construction is complex and consumes money. The solar module provided by the embodiment 2 of the invention achieves the technical effects of cost saving, simplicity and stability.
Traffic accidents occur in a certain proportion, and even under the condition that the highway sign is not inclined, a driver collides with the sign on the roadside due to drunk driving or tired driving and the like. An alarm device is needed to make the operation and maintenance personnel know that the indication board is knocked down at the first time. The smart detection terminal 10 itself does not have an alarm device built therein, and the smart detection terminal 10 may need to extend other functions in addition to the alarm device.
In order to solve the problem that the intelligent detection terminal 10 can expand functions, as shown in fig. 3, the intelligent detection terminal 10 provided in embodiment 2 of the present invention further includes an expansion interface 7; the expansion interface 7 is connected in data communication with the edge computing unit 1. The expanded equipment can be only provided with a plurality of sensors, the data to be collected is sensed through the sensors and is sent to the edge calculation unit 1 on the intelligent detection terminal 10 through the expansion interface for processing, and the processed data can be sent out through the communication unit 4. By adding the expansion interface 7, the function expandability of the intelligent detection terminal 10 is improved, and meanwhile, the expansion equipment can directly use the edge calculation unit 1 and the communication unit 4 on the intelligent detection terminal without a built-in calculation unit and a built-in communication unit 4, so the intelligent detection terminal is light and small in size and can be manufactured with low cost.
The highway sign has much information, except that the information with too large inclination needs to prompt the driver of the passing vehicle, other information passing drivers do not care, but the operation and maintenance personnel of the highway pay attention to the smooth traffic on the road section which is maintained by the operation and maintenance personnel all the time. Some operation and maintenance personnel work in a command center and in various places on the highway, and some operation and maintenance personnel may need to know the real-time condition of the highway when going on a business trip.
In order to solve the problem that the relevant state information of the highway signboard can be sent and transmitted to operation and maintenance personnel on a relevant road section, as shown in fig. 3, the inclination early warning system for the highway signboard provided by the embodiment 2 of the invention further comprises a cloud server 8 and a plurality of display terminals 9; the cloud server 8 is in data communication connection with the intelligent detection terminal 10; the cloud server 8 is in data communication connection with a number of display devices 9. Through a wireless communication technology, the 4G or 5G technology adopted in embodiment 2 of the present invention sends the relevant information of the highway sign to the cloud server 8, and the cloud server 8 collects and processes the data and distributes the data to relevant persons who need to know the data, for example, if the inclination angle of the highway sign is too large and normal vehicle driving is affected, the information is sent to the vehicle-mounted unit of the coming vehicle; in order to avoid that the automobile without the vehicle-mounted unit can obtain relevant data, the information is sent to a variable information board of the expressway; the expressway sign needs to be repaired, and the data are sent to the monitoring screen of the command center and the mobile phone screen of the maintenance personnel, so that the expressway sign is quick and timely, redundant communication between the maintenance personnel and the dispatching personnel of the command center is saved, and the unclear condition caused in the communication is avoided. The technical effect of quickly and accurately transmitting information is achieved.
