Description

Technical Field

[0001] The present application relates to the field of traffic signal control, and in particular to a time calibration method, system and device for a voice controller. Background Art

[0002] The so-called voice controller can be a device for playing the status of traffic lights by voice. The voice controller can be a traffic bell for the blind, for example. Deploying a voice controller such as a traffic bell for the blind at an intersection can help visually impaired people understand the changes in traffic lights at the intersection and ensure that they can cross the road safely. The traffic lights here are the lights that direct traffic operations, and generally show red, green, yellow, etc. A red light means no passage, a green light means passage is allowed, and a yellow light means a warning.

[0003] One of the biggest functions of the voice controller is that it can be controlled adaptively. For example, from 8 pm to 8 am the next day, the voice controller does not work, that is, the device does not play the traffic light status through voice, and works normally at other times, such as the device playing the traffic light status through voice. Based on this, the processor in the voice controller implements the above settings based on the local clock of the voice controller to achieve that from 8 pm to 8 am the next day, the voice controller does not work, that is, the device does not play the traffic light status through voice, and works normally at other times, such as the device playing the traffic light status through voice.

[0004] However, the local clock in the voice controller will deviate after long-term use. Often, the longer the clock is used, the greater the time deviation will be. This time deviation will affect the original settings. For example, the device that originally set the voice controller not to work at 8 pm, that is, not to play the traffic light status through voice, but due to the above time deviation, the voice controller works at 8 pm, that is, the device that plays the traffic light status through voice.

[0005] The conventional solution at present is to manually go to the intersection to dial the clock in the voice controller to calibrate the time, but this manual method is more troublesome. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present application and to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0046] See also Figure 1 , Figure 1 A flow chart of a method provided in an embodiment of the present application. As an embodiment, the method is applied to a signal machine (also called a road traffic signal controller). The signal machine here can change the order of road traffic signals, adjust the timing of traffic lights, and control the state of road traffic lights.

[0047] In a specific application, there is a connection channel between the signal machine and each traffic light at the intersection for directing traffic operation, such as a 220V live and neutral wire (i.e., a live wire and a neutral wire, collectively referred to as a light control output wire). The embodiment of the present application does not change the connection structure between the existing signal machine and the traffic light.

[0048] As an embodiment, if there is a pedestrian passage in the above-mentioned intersection, a voice controller associated with at least one traffic light for controlling traffic on the pedestrian passage is also deployed at the above-mentioned intersection. The voice controller here is such as the blind clock described in the background technology, which is used to play the state of the associated traffic light by voice.

[0049] In this embodiment, the connection structure between the voice controller and each associated traffic light can be an existing connection structure, and no additional devices such as physical devices or logical devices are required. For example, the voice controller is connected to the connection channel between the signal machine and each traffic light associated with the voice controller, such as the above-mentioned light control output line. Figure 2 As shown; for another example, the voice controller is connected to each associated traffic light, as shown Figure 3 Such a connection structure between the voice controller and each associated traffic light, for example, the signal machine directly connects the voice controller through the 220V live and neutral wires of each traffic light associated with the voice controller, without the need for additional means such as network cables, serial cables, wireless or power carriers to achieve the connection of the voice controller.

[0050] Based on the above structure, the voice controller can sense the signal output by the signal machine through the connection channel between any traffic light associated with the voice controller, such as powering on 220V, or powering off.

[0051] Based on the above description, the method provided in the embodiment of the present application is described below:

[0052] like Figure 1As shown, the process may include the following steps:

[0053] Step 101, when it is determined that the first agreed time under the target date has arrived, identify whether the state of a traffic light associated with the voice controller at the intersection is in a flashing state, if not, execute step 102, if yes, execute step 103.

[0054] Here, the first agreed time under the target date refers to the agreed time for calibrating the local clock of the voice controller. Optionally, the target date can be set as the first agreed time of each day or the first agreed time every T days according to actual needs, such as the clock accuracy required by the voice controller, which is not specifically limited in this embodiment. T is greater than 1.

[0055] As for the first agreed time here, it can be agreed in advance by the signal machine and the voice controller and set through the program. For example, it is set through the program before both parties leave the factory. Preferably, the first agreed time can be, for example, 1 a.m. or a time point when the frequency of pedestrians crossing the street is extremely low, to reduce the impact of continuous triggering output on pedestrians' senses. For example: The first agreed time can be set at 1 a.m. or 2 a.m.

[0056] According to the national standard, when a traffic light for directing pedestrian traffic on a pedestrian passage is green, the green light has a duration and a green flashing time. Based on this, identifying whether a state of a traffic light associated with a voice controller at an intersection is in a flashing state includes: identifying whether a state of a traffic light associated with a voice controller at an intersection is in a green flashing state.

[0057] Step 102: Send N consecutive trigger signals through a connection channel of one of the traffic lights associated with the voice controller, so that the voice controller calibrates the time of the local clock to the second agreed time after sensing the N consecutive trigger signals.

[0058] In specific implementation, if N is 1, it may conflict with the defined countdown validity logic, and if N is too large, it will cause too many trigger signals to be sent, causing visual confusion to pedestrians. Based on this, after experiments, this embodiment recommends that N is 3. It should be noted that N is 3 for example only and is not intended to be limiting.

[0059] In addition, the time interval between two adjacent trigger signals here is different from any flashing time of the traffic light in the flashing state. For example, referring to the above green flashing time, the time interval between two adjacent trigger signals is different from the green light flashing time. If the green flashing time is 500ms, the time interval between two adjacent trigger signals is 250ns.

[0060] It should be noted that the trigger signal here is also the time for triggering the traffic light to flash, which can be a pulse signal.

[0061] In specific implementation, since the time it takes for the signal machine to continuously send N trigger signals is not too long, this error will not have a significant impact on the actual use of the local clock in the voice controller. At this time, the second agreed time can be the same as the first agreed time.

[0062] Alternatively, considering the clock accuracy requirement, as an embodiment, the second agreed time may be a time after the first agreed time and satisfying a first set time difference with the first agreed time. The first set time difference here can be set according to actual needs, such as the time of N consecutive trigger signals, etc., which is not specifically limited in this embodiment.

[0063] Step 103, wait until the status of any traffic light associated with the voice controller at the intersection is not flashing, and then send N consecutive trigger signals through the connection channel of one of the traffic lights associated with the voice controller, so that the voice controller calibrates the local clock time to the third agreed time after sensing N consecutive trigger signals.

[0064] That is to say, if the state of the traffic light associated with the voice controller at the intersection is flashing, it will wait until the flashing state ends. In specific implementation, the duration of the traffic light in the flashing state is generally not too long. Such an error has a great impact on the actual use of the local clock in the voice controller. Under this premise, the third agreed time can be the same as the first agreed time.

[0065] As another embodiment, the third agreed time may also be a time after the first agreed time and satisfying a second set time difference with the first agreed time; the second set time difference is different from the first set time difference. For example, the second set time difference is determined based on the above-mentioned waiting time and the first set time difference (optionally, the second set time difference may be the sum of the above-mentioned waiting time and the first set time difference).

[0066] So far, completed Figure 1 The process shown.

[0067] pass Figure 1 As can be seen from the flow, in this embodiment, a continuous N-time trigger signal is sent through the connection channel between the signal machine and one of the traffic lights associated with the voice controller, so that the voice controller can calibrate the time of the local clock after sensing the continuous N-time trigger signal, which can automatically realize the time calibration of the clock in the voice controller. According to this method, the time error of the clock in the voice controller can be controlled within 1 minute.

[0068] Furthermore, this embodiment automatically realizes the time calibration of the clock in the voice controller with the help of the existing connection structure between the signal machine and the voice controller. There is no need to use high-precision clock crystal oscillators, additional 4G, GPS, wireless devices, and no need to add any new hardware equipment. It has strong scalability.
