Description

Technical Field

[0001] This application relates to the field of signal lights, and specifically relates to a signal light that is convenient for expansion and can realize information collection and display. Background Art

[0002] Signal lights are the most common devices used for traffic indication. Traffic signal lights are generally used in conjunction with traffic signal controllers. With the progress of digital and Internet of Things technologies, existing traffic signal lights are gradually connected to the municipal management system, which can realize remote control and remote modification of the lighting program of signal lights. Moreover, with the increasing richness of urban life, more and more information needs to be displayed on the road, and there is also more traffic indication information. And after a period of time, the traffic indication information may also change. Therefore, it is necessary to replace the external signs of traffic lights, etc. In addition, visibility has a relatively large impact on traffic indication. After many existing traffic signal lights are installed, it is very inconvenient to externally replace or add facilities, and it cannot meet the needs of using modern traffic signal lights. However, if a traffic signal light that can be easily externally connected to devices can be set up, so as to collect information, display information, install and replace traffic indication signs, it will greatly increase the multifunctionality of the use of signal lights and also better meet the needs of expansion use.

[0022] By installing sensors, information around the signal lamp can be collected. For example, according to the visibility at the installation position of the signal lamp, the brightness of the signal lamp can be adjusted, so as to achieve a clearer indication.

[0023] The display unit, the temperature sensor, the humidity sensor and the visibility sensor can adopt existing display units and sensors. And they are installed at the strip-shaped mounting through grooves on the mounting substrates of the present application through corresponding structures. Installing corresponding devices through the strip-shaped mounting through grooves is a common mounting and connecting structure in the mechanical field, and can be realized by using existing technologies.

[0024] Further, a touch screen is mounted on the panel, and the touch screen is connected to the control unit.

[0028] Further, the back plate is fixedly connected to the first side plate, the second side plate, the top plate and the bottom plate by bolts.

The two rubber pressing blocks 4.3.4 can press against the movable sleeve 5.6.3. The lifting unit can be in a first height, a second height, a third height, and a fourth height. When the lifting unit is in the first height, all the mounting substrates 4 are in the initial state, and each mounting substrate 4 is surrounded by the convex edge portion 5.2 of the corresponding pressing unit, and the convex edge portion 5.2 of each pressing unit abuts against the corresponding horizontal bearing plate 3. When the lifting unit is in the second height, for the mounting substrate 4 in the first state, the second state, or the third state, its upper surface is abutted by the convex edge portion 5.2 of the corresponding pressing unit. When the lifting unit is in the third height, the movable sleeve 5.6.3 clamped by the two rubber pressing blocks 4.3.4 stays between the two rubber pressing blocks 4.3.4, and the second spring 5.6.2 corresponding to the movable sleeve 5.6.3 is stretched. The lower surface of the movable sleeve 5.6.3 not clamped by the two rubber pressing blocks 4.3.4 is higher than the upper surface of the corresponding mounting substrate 4. When the lifting unit is in the fourth height, the lower surfaces of all the movable sleeves 5.6.3 are higher than the upper surfaces of the corresponding mounting substrates 4. The first height, the second height, the third height, and the fourth height increase in sequence. The first slider 4.1 and the second slider 4.2 are both cylindrical sliders.

[0051] As shown in the figure, the signal lamp of the present application has the function of directing traffic of a general signal lamp, and can perform remote communication. The information collected by the signal lamp can be remotely transmitted, and the execution program of the signal lamp can be modified remotely at the control center. As shown in the figure, the signal lamp of the present application has a plurality of mounting substrates in the lamp post box body, and the mounting substrates can be drawn out from the front panel, the back panel or the first side panel, so as to realize the installation of external expansion devices by drawing out from a suitable direction according to needs. For example, when a display needs to be installed, the mounting substrate is drawn out from the direction of the first side panel for installation, and the sensor can be installed by drawing out the mounting substrate from the direction of the front panel or the back panel. The mounting substrate has a strip-shaped mounting through groove, so the installation is very convenient, and any required display device, traffic sign or sensor can be installed. When temperature, humidity and visibility sensors are installed, the brightness of the signal lamp can be adjusted according to the information of the sensors, so as to better direct traffic.

[0052] As shown in the figure, it is only necessary to raise the lifting unit to the third height, and then the mounting substrate can be pulled out in the required direction. After pulling out, lower the lifting unit to the second height to press the mounting substrate. The lifting of the lifting unit can be achieved by a motor, and after adjusting to the corresponding height, it can be locked by a lock nut, so that the pressing unit at the lifting unit presses and fixes each mounting substrate. And two pressure sensors are provided at each pressing unit. When the mounting substrate is in the third state, the movable blocks of the two pressure sensors abut against the mounting substrate. When the mounting substrate is in the first or second state, one of the movable blocks abuts against the mounting substrate, and the other movable block abuts against the horizontal bearing plate. When the lifting unit and each mounting substrate are stably installed and there is no strong wind, the measured values of each pressure sensor should be stable and unchanged. When the measured value of the pressure sensor corresponding to the movable block abutting against the horizontal bearing plate shows a certain degree of jitter change, especially when the measured values of the pressure sensors corresponding to multiple movable blocks abutting against the horizontal bearing plate show a certain degree of jitter change, it indicates that the lifting unit is not firmly installed; when the measured value of the pressure sensor corresponding to the movable block abutting against the mounting substrate shows a certain degree of jitter change, it indicates that this mounting substrate is not stably installed (for example, the mounting substrate shakes to a certain extent due to unstable installation in the case of strong wind). In either case, the control unit can control an alarm to the remote control center to remind maintenance. And theoretically, the measured value of the pressure sensor corresponding to the movable block abutting against the mounting substrate is much larger than that of the pressure sensor of the mounting substrate abutting against the horizontal bearing plate. Therefore, it is very easy for the control unit to identify which sensor's movable block abuts against the mounting substrate and which pressure sensor's movable block abuts against the horizontal bearing plate.

[0053] In addition, when not all the mounting substrates are initially used and only a part of the mounting substrates are used, and additional mounting substrates are to be added later, it is only necessary to raise the lifting unit to the third height, and then the mounting substrates that need to be added can be pulled out. However, at this time, the movable sleeves inserted into the limiting jacks (the first limiting jack, the second limiting jack or the third limiting jack) of the mounting substrates that have been used still remain in the limiting jacks and are tightly pressed by two rubber pressing blocks, and the second spring of the movable sleeve is stretched and elongated. When the lifting unit descends and returns to the second height, the limiting jacks and the inserting limiting units of the mounting substrates that have been used before do not need to be repositioned, so that the operation of adding mounting substrates is more convenient.

[0054] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
