Description

Portable control device and wireless sensor control system

Technical Field

The present invention relates to the field of wireless sensor network technologies, and in particular, to a portable control device and a wireless sensor control system using the same.

Background

In the era of wired sensors, when a wired sensor product is installed and used on site, an engineer only needs to use a matched cable to directly connect a sensor and a collector, and the connection topological structure is visual and clear.

After the wireless sensor era, cables are not needed, so that the trouble of wiring is avoided, the arrangement depth of the sensors is prolonged, and the places where the traditional wired sensors cannot reach due to the limitation of the cables can be monitored by the wireless sensors.

However, the wireless sensor is extremely troublesome when networking in the field. Since the communication distance of the wireless sensor node can reach 100 meters to 1000 meters generally, in the communication distance range of the scale, the wireless sensor node can be connected to any gateway which complies with the same standard within the wireless coverage radius range, and in most of the time, due to the complexity of the field condition, the field engineering staff can be out of the visual field range between the wireless sensor node and the wireless gateway, and in addition, most of the wireless sensor nodes are small in size and possibly lack of indicator lamps, so that the wireless sensor node which is not connected with the wireless gateway can be in any state, the field staff is often confused and embarrassed, and furthermore, the application popularization and further popularization of the wireless product are often hindered due to the difficulty in networking.

Meanwhile, with the development of wireless sensor network technology and the mass installation and practical use of wireless sensor node products in industrial fields, the situation that a plurality of wireless sensor network systems may exist simultaneously in a limited space area is increased remarkably in practical construction, and in this situation, because necessary display and input keys are lacked on the wireless sensor nodes, the task of adding the current wireless sensor nodes to a specified wireless gateway in field application becomes very troublesome and is very easy to cause problems.

In practical engineering application, in order to solve the grouping of wireless sensor network products, the following grouping methods are common in engineering:

the first grouping method is a multi-bit toggle switch. The wireless gateway and the wireless sensor nodes are provided with the dial switches, when wireless grouping is carried out on an engineering site, as long as the dial switches of the wireless gateway and the wireless nodes are dialed to be the same value, the dial switches can be the same value and are worth dividing the wireless gateway and the wireless sensor nodes into a group, and therefore a plurality of networks with different values of the dial switches can coexist in the same space and cannot be confused. However, the problem of this implementation is that the number of bits of the dial switch is generally not too long, and is usually 4 bits, and if there is the same product in the wireless coverage area for other users, the same code is likely to cause the cross-talk between devices. According to the existing constraint conditions, the communication distance of the wireless sensor network can reach 1 km, and some wireless sensor networks are even longer, so that a wireless network can cover an area of about 3 to 4 square kilometers or more, and in the area, finding out similar wireless products used by other users is obviously very difficult. Secondly, as dial switches are mostly designed in the equipment, operation procedures such as shell removal and the like need to be carried out on the wireless gateway and the wireless sensor node by using the mode, and the problems that the internal circuits of the wireless gateway and the wireless sensor node are damaged and the waterproof performance of the wireless sensor node is reduced and the like due to the fact that the field environment is much worse than the production environment and the field removal and the installation can cause different degrees are solved; in addition, if the dial is designed outside the equipment, the dial is easy to be operated by mistake and the problems of water resistance and the like are difficult to solve; if the dial switch is arranged in an independent protection bin, the structure of the wireless sensor node becomes complicated; moreover, the field personnel can also have the situation that two or more groups of wireless gateways adopt the same dial codes due to work errors or construction by multiple persons.

The second grouping method is by way of wired configuration of the computer. The computer may also be a cell phone, tablet, or other customized portable screen-equipped device. On the industrial application site, an engineer connects a computer with a wireless gateway (or a wireless sensor node) through a wired cable, then runs corresponding configuration software at the computer end, and writes specified networking grouping parameters into the wireless gateway and/or the wireless sensor node through a series of read-write operations. Because the related networking grouping parameters are obtained and more parameters can be set, the networking selection of the product can be limited through the user identification information. In the technical aspect, the parameters are configured directly through wires, which is a better implementation mode, but most small wireless sensor nodes have no relevant interfaces, and need to be disassembled on site, and some sites have limitations on using computers.

The third grouping method is to perform wireless configuration grouping through a special read-write device. The dedicated read-write device may be a customized development device, such as a coder, a handsheet device, or a device that is only used to complete a certain specified function, or a device that is developed by a computer, a mobile phone, a tablet computer, or other device with a screen and is equipped with a wireless component to implement a corresponding function. The wireless configuration parameters are adopted to solve a great problem, namely how to wake up the wireless sensor node in the dormancy to quickly connect the special read-write equipment, and in practical engineering, two ways are adopted to wake up the wireless sensor node in the dormancy to quickly connect the special read-write equipment: one is that a key with a pre-reserved function is designed on a wireless sensor node, and the wireless sensor node is immediately awakened and re-accessed to the network by triggering the key; for a wireless sensor node with waterproof requirements and keys which are inconvenient to design, magnetic sensing elements such as reed pipes are often arranged in the wireless sensor node, in engineering application, the wireless sensor node is awakened by a magnet passing through the wireless sensor node or other similar modes, the function is equivalent to the keys, and the design such as hole opening is not carried out on the appearance of the wireless sensor node, so that the waterproof requirements are met. Through the two modes, the wireless sensor node is accessed to the special read-write equipment by utilizing the network establishment characteristic of the equipment within a short time after being started. However, there are many problems in this way, for example, in the case of no priority, after the wireless sensor node wakes up, there is a possibility that another dedicated read-write device or another gateway in the same area may join; if the priority of the special read-write equipment is set to be higher than that of the wireless gateway which is actually used, the gateway can be preferentially added into the special read-write equipment, however, when a plurality of special read-write equipment exist in a wireless coverage area of a few square kilometers, the wireless sensor node still can be added into the special read-write equipment which is far away and has higher priority, and the special read-write equipment which the engineering personnel hope to be added into is not added; if the special read-write equipment closest to the special read-write equipment is judged by using information such as field intensity, other special read-write equipment can be added due to the fact that a wireless link of the special read-write equipment has problems or temporary interference, and it can be seen that defects and loopholes still exist in the mode of performing parameter configuration in a wireless mode.

The fourth grouping method is a manual automatic grouping method. The method does not need additional equipment, and various implementation modes exist in engineering application, for example, by simultaneously pressing keys of a gateway and wireless sensor nodes or other similar operations, the operation enables the gateway to be changed from a conventional network access permission mode of prohibiting the wireless sensor nodes from accessing the network into a network access permission mode within a short time, at the moment, if the wireless sensor nodes immediately request networking, under the condition that the time is matched correctly, the specified wireless sensor nodes can be added into the corresponding gateway, but if the network access permission time reserved by the gateway is longer, the wireless sensor nodes which are close to the gateway and are currently in a power-on state are likely to be added into the gateway; if the allowed network access time reserved by the gateway is short, the triggering networking has higher requirement on time coordination during operation.

In addition, with the development of advanced manufacturing processes, the size of the wireless sensor node is smaller and smaller, and some auxiliary structures are more and more difficult to integrate into the wireless sensor node, for example, structures for performing a switching function, and with the reduction of the size of the wireless sensor node, the button-type structure is less and more difficult to design on the surface of the wireless sensor node, and although the screw-type switch combined with the housing of the wireless sensor node can have the button-type structure, the wireless sensor node may be installed in a position difficult to reach by a worker, which results in difficulty in operating the screw-type switch. Meanwhile, no matter the switch is a screw-on switch or a key-press switch, the waterproof requirement of the wireless sensor node is difficult to guarantee.

Therefore, how to realize the convenient and fast control of the on-off of the wireless sensor node in the field application, and establish the connection and grouping of the wireless sensor node and the wireless gateway, so as to avoid the connection grouping of the wireless sensor node and other wireless gateways by mistake, becomes a problem to be solved urgently.

The first embodiment of the present invention may be used for connection and networking between a wireless node and a wireless gateway in a wireless sensor network, where the wireless node device 2 may be a wireless sensor node, a wireless router, a wireless relay node, etc. in the wireless sensor network.

In the wireless sensor system according to the first embodiment of the present invention, a fast touch grouping technology is adopted, and a dedicated grouping circuit for fast touch is added to an existing wireless gateway and an existing wireless node device, so that a novel wireless gateway and a wireless node device are formed, and the wireless node device and the wireless gateway have a fast touch grouping capability. In practical industrial field application, after the wireless node device 2 approaches or bumps a designated position (i.e. the sensing part 11) on the wireless gateway 1, the wireless node device can be waken up quickly and join the current wireless gateway no matter what the original state of the wireless node device is, so as to realize quick grouping of the wireless sensor network. The specific flow is described below.

In the first step, in the industrial field, when the wireless node device 2 approaches or contacts the sensing part 11 of the wireless gateway 1, the proximity touch sensing unit 12 in the wireless gateway 1 immediately detects the behavior, and the proximity touch sensing unit 12 informs the gateway networking processing unit 15 in the wireless gateway 1 that the wireless node device 2 needs to be quickly networked with the wireless gateway 1.

And secondly, immediately starting the awakening signal transmitting unit 13 after the gateway networking processing unit 15 learns that the wireless node device 2 and the wireless gateway 1 are close to touch, wherein the awakening signal transmitting unit 13 transmits wireless electromagnetic wave energy outwards in a low-frequency, high-frequency or ultrahigh-frequency mode through a wireless transmitting coil, and simultaneously, networking data information such as a networking identification code, a gateway channel, a gateway group number, a check code and the like which is transmitted outwards by taking electromagnetic waves as a carrier can be transmitted continuously and repeatedly at regular time until the networking data information is stopped after being overtime.

Thirdly, because the wireless node device 2 and the wireless gateway 1 are in a close or contact state, the wireless transmitting coil of the wireless gateway 1 and the wireless receiving coil of the wireless node device 2 are very close, the wireless receiving coil of the wireless node device 2 receives corresponding electromagnetic energy and informs the wake-up signal receiving unit 21, the wake-up signal receiving unit 21 firstly performs self-gain adjustment, adjusts the amplification gain of the received signal to a proper value, then wakes up the node networking processing unit 22 in a sleep period, and then sends the received networking data information to the node networking processing unit 22.

Fourthly, after the node networking processing unit 22 is awakened, analyzing the received networking data information, distinguishing whether the networking identification code is correct or not, and if the networking identification code is incorrect, entering the sleep again to avoid power consumption caused by interference signals; if the networking identification code is correct, the node networking processing unit 22 continues to receive all networking data information, and acquires the wireless radio frequency networking information including, but not limited to, a channel number, a gateway group number, and the like, which is sent by the wireless gateway 1, under the condition that the check code is correct. In an alternative embodiment, the node networking processing unit 22 may be powered independently, and the power control circuit 23 for powering the entire wireless node device 2 is not required to be turned on when the node networking processing unit 22 is awakened. In an alternative embodiment, the wake-up signal receiving unit 21 may be powered by the electromagnetic wave received by the wireless receiving coil, and in an alternative embodiment, the wake-up signal receiving unit 21 may be powered independently, and when the wake-up signal receiving unit 21 operates, the power control circuit 23 for powering the whole wireless node device 2 to operate does not need to be turned on.

Fifthly, the node networking processing unit 22 detects whether the power control circuit 23 is turned on or not under the condition that the correct gateway channel, group number and other information is obtained, if the power control circuit 23 is not turned on, the node networking processing unit 22 controls the power control circuit 23 to turn on power supply, and if the power control circuit 23 is turned on, the node networking processing unit 22 sends the current gateway channel, gateway group number and other networking information to the node radio frequency communication unit 24 and requests immediate networking.

Sixthly, the node radio frequency communication unit 24 can rapidly request to access the wireless gateway 1 and establish bidirectional networking with the wireless gateway 1 because the current channel and gateway group number of the wireless gateway 1 are known, and meanwhile, the wireless node device 2 writes the related information of the wireless gateway 1 into the nonvolatile memory 25 thereof so as to rejoin the wireless gateway 1 after the next power failure or reset.

Seventhly, the gateway radio frequency communication unit 14 informs the gateway networking processing unit 15 after networking is successful, the gateway networking processing unit 15 controls the wakeup signal transmitting unit 13 to be closed and reminds a user of successful networking through the state display unit 16, and otherwise, the wakeup signal transmitting unit 13 prompts failure through the state display unit 16 after transmitting the wireless electromagnetic wave energy overtime.
