The big data service system 104 may be implemented by a separate server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, there is provided an operation control method of a vehicle, which is described by taking the method as an example applied to the wireless terminal 102 in fig. 1, and includes the following steps:
in step S201, historical operating data of the carrier device is acquired.
The historical operation data of the carrier device may include data, such as a load rate, a flow rate of a carrier passage opening, an operation speed, and an energy-saving operation mode of the carrier device, recorded in the operation of the carrier device before the current operation of the wireless terminal 102. The historical operation data may be corresponding operation data of each day and each time period in the past year, or operation data of working days, weekends and holidays processed and analyzed by the wireless terminal 102.
After the wireless terminal 102 processes the historical operating data, the historical operating data is uploaded to the big data service system 104 through a wireless network, or may be directly stored in a storage module of the wireless terminal 102. The energy-saving operation mode may be that the operation speed of the carrier device in the next operation period is determined according to the load factor of the carrier device in the previous operation period, the flow rate of the carrier passage opening and the operation speed, and the current operation speed of the current operation period is determined according to the flow rate of the carrier passage opening in the current operation period. The operation speeds comprise a minimum operation speed, a first operation speed closest to the minimum operation speed, a rated operation speed and a second operation speed which is greater than the first operation speed and less than the rated operation speed. The minimum operation speed is an operation speed closest to the operation stop speed and less than the rated operation speed or an operation speed at the operation stop, and for example, the minimum operation speed may be 0 speed. The first operating speed is the speed closest to the minimum operating speed, for example, the first operating speed may be 0.2 times the nominal operating speed. The second operation speed can be a speed interval corresponding to the load factor and the operation speed of the carrying equipment in a specific period, so that the carrying equipment can have more operation speed options between the first operation speed and the rated operation speed, and a refined energy-saving control effect is realized. The normal running speed of the carrier equipment with the rated running speed can be determined according to factory settings and industry standards of the carrier equipment or actual conditions of a putting area of the carrier equipment.
In a specific implementation, according to the current operation cycle data, the wireless terminal 102 retrieves the historical operation data of the historical operation cycle corresponding to the current operation cycle from its storage module or from the big data service system 104.
Step S202, according to the running speed of the carrying equipment in the historical running period corresponding to the current running period in the historical running data, the initial running speed of the current running period of the carrying equipment is determined.
The historical operating cycle corresponding to the current operating cycle may be a cycle corresponding to each time interval every day in the past year, or may be a cycle of holiday arrangement issued by the past year government corresponding to holiday arrangement issued by the present year government. The initial running speed is the running speed executed when the carrying equipment starts running in the current running period, and the initial running speed is determined according to the running speed in the historical running period corresponding to the current running period. When the carrying equipment is put into use for the first time, the first running speed is used as the initial running speed.
In a specific implementation, the wireless terminal 102 may use the operation speed in the historical operation data of the carrier device in a certain period of time in the previous year on a certain date as the initial operation speed in the same period of time on the same date in the current year. The wireless terminal 102 may use the operation speed in the historical operation data of the carrier during the period scheduled on a holiday of a certain previous year as the initial operation speed during the period scheduled on the same holiday of the current year. Generally, the load rate of the carrying equipment in the current annual operation period of the same carrying equipment, the flow of the carrying channel port and historical operation data of the previous annual corresponding operation period have relevance and consistency in the change rule, the historical operation data of the historical operation period corresponding to the current operation period is taken as a basis, a reliable basis is provided for determining the initial operation speed of the current operation period, and the accuracy of obtaining the current operation speed of the carrying equipment and the operation control efficiency are improved.
Step S203, obtaining the current carrying channel port flow of the carrying device.
Wherein the carrying passage opening of the carrying device may comprise an inlet and an outlet. The flow of the carrying channel of the carrying device may be the flow of the carrying object at the entrance and exit of the carrying device measured by the sensing module 108 at the entrance and exit of the carrying device, and the wireless terminal 102 determines the operation speed adjustment scheme of the carrying device according to the flow of the carrying channel, so as to avoid congestion at the entrance and exit of the carrying device.
In a specific implementation, the wireless terminal 102 may sense a moving direction of a carrying object at an entrance of a carrying device from the sensing module 108, determine whether the carrying object is to enter the carrying device, respond to the carrying object about to enter the carrying device, and not respond to the carrying object passing through the entrance and exit of the carrying device and not entering the carrying device. The wireless terminal 102 may sense the movement of the carrying object at the outlet of the carrying device from the sensing module 108, determine that a congestion occurs, and the carrying device may respond and adjust the operation speed.
Step S204, when the flow of the carrying channel port is larger than a preset flow threshold value of the carrying channel port, adjusting the initial running speed based on the inlet and outlet attributes corresponding to the flow of the carrying channel port to obtain the current running speed of the carrying equipment.
The flow threshold of the carrying channel port is a threshold used for indicating that the carrying channel port is in a congestion state, and may be determined according to historical operating data, actual observation data or industry standard data. The current running speed is the running speed of the carrying equipment obtained after the initial running speed is adjusted according to the flow of the carrying channel port.
In a specific implementation, when the traffic of the carrying channel port obtained by the wireless terminal 102 from the sensing module 108 is greater than the corresponding traffic threshold, it is determined that the carrying channel port is in a congestion state, and an initial operation speed needs to be adjusted to ensure operation safety. Specifically, the initial operation speed is raised or the operation is performed at the rated operation speed to increase the number of the carried objects transported per unit time when the entrance of the carrying passage is congested, and the initial operation speed is lowered or the operation is performed at the minimum operation speed to decrease the number of the carried objects reaching the exit of the carrying passage when the exit of the carrying passage is congested. When the traffic of the carrying channel port acquired by the wireless terminal 102 from the sensing module 108 is less than or equal to the corresponding traffic threshold, controlling the carrying device to maintain the initial running speed to run.
And step S205, controlling the carrying equipment to operate according to the current operation speed in the current operation period.
In a specific implementation, the wireless terminal 102 controls the carrying device to operate according to the current operating speed determined in step 204, so as to solve the congestion situation at the exit and entrance of the carrying channel.
After acquiring the operation data of the carrier device in the current operation period, the wireless terminal 102 saves and updates the operation data to the storage module of the wireless terminal 102 in units of years or any other suitable statistical period, and uploads the operation data to the big data service system 104, where the operation data in the current operation period includes an operation speed, a corresponding date, a traffic of a carrier channel port, and the like.
In the operation control method of the carrying equipment, by acquiring the historical operation data of the carrying equipment, determining the initial running speed of the current running period according to the running speed of the carrying equipment in the historical running period corresponding to the current running period in the historical running data, when the current carrying channel port flow of the carrying equipment is greater than the carrying channel port flow threshold value, adjusting the initial running speed according to the inlet-outlet attribute corresponding to the flow of the carrying channel port to obtain the current running speed of the carrying equipment, and controls the carrying equipment to operate according to the current operating speed, so that the carrying equipment can determine the current initial operating speed according to historical operating data corresponding to historical operating periods, the accuracy and the efficiency of determining the operating speed of the carrying equipment are improved, and simultaneously, when the channel port of the carrying equipment is jammed, the running speed is adjusted in time, and the running safety and the running control efficiency of the carrying equipment are improved.
In one embodiment, the carrying port traffic may include an inlet traffic of the carrying port, and step S204 includes:
and when the inlet flow is greater than the inlet flow threshold value and the initial running speed is less than the rated running speed, the initial running speed is increased to obtain the current running speed.
In the present embodiment, the inlet flow threshold value is a flow value indicating inlet congestion at the carrying channel port.
The wireless terminal 102 obtains the entrance flow of the carrying channel port measured by the sensing module 108, and when the entrance flow is greater than an entrance flow threshold, it is determined that the entrance of the carrying channel port is in a congestion state, so as to avoid an accident caused by entrance congestion, the wireless terminal 102 may adjust an initial operation speed to increase the number of carried objects transported in unit time, and alleviate entrance congestion. Specifically, when the initial operating speed of the carrying device is less than the rated operating speed, the initial operating speed may be increased. When the initial operating speed of the carrying device is equal to the rated operating speed, the rated operating speed is maintained to operate.
According to the embodiment, when the inlet flow of the carrying channel port is larger than the inlet flow threshold, the running speed of the carrying equipment is increased, so that the running speed of the carrying equipment is adjusted in time when the carrying equipment is jammed at the inlet, and the running safety and the running control efficiency of the carrying equipment are improved.
In one embodiment, the carrier port traffic may include outlet traffic of the carrier port, and step S204 includes:
and when the outlet flow is greater than the outlet flow threshold value and the initial running speed is greater than the minimum running speed, reducing the initial running speed to obtain the current running speed.
In the present embodiment, the outlet flow threshold is a flow value indicating outlet congestion at the carrying channel port.
The wireless terminal 102 obtains the outlet flow of the carrying channel port measured by the sensing module 108, and when the outlet flow is greater than an outlet flow threshold, it is determined that the outlet of the carrying channel port is in a congestion state, so as to avoid an accident caused by outlet congestion, the wireless terminal 102 may adjust an initial operating speed to reduce the number of transported carrying objects reaching the outlet in unit time, and alleviate the outlet congestion. Specifically, when the initial operating speed of the carrier is greater than the minimum operating speed, the initial operating speed may be reduced. When the initial operating speed of the carrier is equal to the minimum operating speed, the minimum operating speed operation is maintained.
According to the embodiment, when the outlet flow of the carrying channel port is larger than the outlet flow threshold, the running speed of the carrying equipment is reduced, so that the running speed of the carrying equipment is reduced in time when the outlet is jammed, and the running safety and the running control efficiency of the carrying equipment are improved.
In one embodiment, after controlling the vehicle to operate at the current operating speed in the current operating period, the method further includes:
acquiring the load rate of the carrying equipment in the current operation period; comparing the load rate to a load rate threshold of the vehicle; and determining the running speed of the carrying equipment in the next running period according to the comparison result and the current running speed.
In this embodiment, as shown in fig. 3, the wireless terminal 102 obtains the load rate of the carrying device within a certain time through the speed adjusting module 106, obtains the pedestrian volume at the carrying passage opening within a certain time through the sensing module 108, and sets a corresponding operating speed and an energy-saving operating mode according to the load rate and the pedestrian volume, so as to achieve an optimal energy-saving effect. The operating speeds may include a minimum operating speed, a first operating speed closest to the minimum operating speed, a nominal operating speed, and a second operating speed greater than the first operating speed and less than the nominal operating speed. Corresponding to different running speeds, a load rate threshold value is set, wherein the load rate threshold value is a monitoring standard value indicating the human flow of the carrying equipment in a certain period and can be determined through historical running data, empirical data or an industry standard of the carrying equipment. The load rate threshold can be used for determining the running speed of the carrying equipment when a carrying object enters in the next running period according to the load rate L of the current running period, so that the running control efficiency of the carrying equipment is improved.
The load rate L of the carrying device in the current operation cycle may be counted by the load rate in the transport time T of one complete carrying object. Assuming that the carrying equipment is started for the first time and has no historical operation data, the carrying equipment starts to operate at a first operation speed, when the wireless terminal 102 detects that the flow of a carrying channel opening exists, the carrying equipment enters the carrying object to carry time to be timed and accelerates to a rated operation speed, and after the timed time reaches T, the 1 st load rate L is obtained 0 . Cumulative over time, load factor L 0 Calculating a plurality of L in the current operation cycle by obtaining in the latest T time period 0 The average value of the load values is obtained to obtain the load rate L of the carrying equipment in the current operation period. The load rate L is used as a basis for determining the operation speed when the wireless terminal 102 detects that the carrying device has the carrying channel port traffic in a future period.
The comparison result of the load rate L and the load rate threshold value of the current operation period is used for judging the flow rate of the carrying object in the current operation period, and when the load rate is greater than or equal to the load rate threshold value, the flow rate of the carrying object of the carrying equipment in the current operation period is judged to be large; and when the load rate is smaller than the load rate threshold value, judging that the flow of the carrying object of the carrying equipment in the current operation period is small.
In specific implementation, the wireless terminal 102 obtains the load rate of the carrying device in the current operating period recorded by the speed regulation module, compares the load rate with the load rate threshold of the carrying device, determines the variation trend of the current pedestrian volume, and determines the operating speed of the carrying device in the next operating period by combining the current operating speed. When the load rate and the load rate threshold in the current period are different, the wireless terminal 102 predicts the traffic of the carrying object of the carrying equipment in the next period, and adjusts the running speed of the carrying equipment when the carrying object enters in the next running period, so as to dynamically adjust the running speed according to the actual traffic environment of the carrying object of the carrying equipment, so as to match the need of carrying object transmission under different load rates, and improve the running control efficiency of the carrying equipment. When the load factor is greater than the load factor threshold, the wireless terminal 102 updates the stored historical operation data of the historical operation cycle corresponding to the current operation cycle of the carrying device as the operation data of the corresponding operation cycle of the current year. The wireless terminal 102 may upload the updated historical operating data to the big data service system 104.
According to the embodiment, the running speed of the next running period when the carrying object enters is determined according to the comparison result of the load rate and the load rate threshold value in the current running period of the carrying equipment and the current running speed, and the running control efficiency of the carrying equipment is improved.

and when the load rate is greater than or equal to the maximum load rate threshold, controlling the carrying equipment to operate at the rated operation speed when the carrying channel port flow is detected in the next operation period.
In this embodiment, the first operating speed is the operating speed closest to the minimum operating speed of the vehicle. The wireless terminal 102 detects the traffic of the carrying channel port, which means that a carrying object enters the carrying channel port. The load factor minimum threshold may be 0 or a value closest to 0 and smaller than the load factor maximum threshold.
In specific implementation, when the load rate L of the carrying equipment in the current operation period is greater than or equal to the maximum load rate threshold value L 2 During the next operation period, when the wireless terminal 102 detects that the traffic of the carrying passage opening is present, the wireless terminal operates at a rated operation speed. When the wireless terminal 102 is not checkedWhen the flow of the carrying channel opening is measured, the carrying equipment maintains the first running speed to run so as to realize energy conservation. The wireless terminal 102 updates the stored historical operation data of the historical operation period corresponding to the current operation period of the carrier as the operation data of the corresponding operation period of the current year. The wireless terminal 102 may upload the updated historical operational data to the big data service system 104.

and when the load rate is smaller than the maximum load rate threshold and larger than the minimum load rate threshold, controlling the carrying equipment to operate at a second operation speed when the next operation period detects that the flow of the carrying channel port exists.
In this embodiment, the second operating speed is greater than the first operating speed and less than the rated operating speed. When the load rate L in the current operation period is larger than the maximum load rate threshold value L 2 And is less than the minimum threshold L of the load factor 1 Meanwhile, the wireless terminal 102 determines that the traffic of the carrying object in the current operation period is general, and then the probability that the traffic of the carrying object in the next operation period is also general is higher, and the operation speed in the next operation period needs to be increased on the basis of the first operation speed to achieve the carrying object transportation efficiency. Meanwhile, the load rate of the carrying equipment does not exceed the maximum load rate threshold L 2 The transportation requirement of the carrying object can be met by operating at the speed lower than the rated operation speed, and meanwhile, the energy-saving effect is achieved.
In the above embodiment, when the load rate is less than the maximum load rate threshold L 2 And is greater than the minimum load factor threshold L 1 When it is time, control the movementAnd the carrying equipment runs at a second running speed when detecting that the flow of the carrying channel port exists in the next running period, so that the running control efficiency and the energy-saving efficiency of the carrying equipment are improved.

In this embodiment, when the load rate in the current operation period is less than or equal to the minimum load rate threshold L 1 Meanwhile, the wireless terminal 102 determines that the traffic of the carrying object in the current operation period is small, and then the probability that the traffic of the carrying object in the next operation period is small is high, so that the first operation speed is used for maintaining the operation, the carrying object transportation efficiency can be met, and the energy-saving effect is achieved.
In the above embodiment, when the load factor is less than the minimum load factor threshold L 1 And meanwhile, the carrying equipment is controlled to run at the first running speed in the next running period, so that the running control efficiency and the energy-saving efficiency of the carrying equipment are improved.
